It is necessary to consider that since it is a congenital deformity, surgical management must consider the patient’s growth process, as well as the healing itself from the surgery. The present study aims to evaluate an alternative solution to secondary rhinology, aesthetic, and functional alterations to unilateral or bilateral cleft lift palate to minimize deformities and ensure good results. 11 patients were studied between 1995 to 2002, ten male and one female. In 8 cases, the patients had a history of cleft lip and palate on the left side, 2 patients with cleft lift palate on the right, and 1 patient with bilateral cleft lip and palate. 100% of the patients increased their naso-labial angle. This improved their appearance and structure, starting from a preoperative arithmetic mean of 39 degrees to a postoperative arithmetic mean of 96 degrees. Such intervention increased the naso-labial angle by 57 degrees. At the base of the nose, it was possible to improve the inclination of the alar line (line B) in 10 of the cases with a variation of 2 to 3 mm in relation to the perpendicular line A and only one case remained with the same inclination.展开更多

Individuals with UCLP;32 clefts were on the left side and 18 clefts were on the right side. Permanent third molar teeth deficiency was excluded from the study. <strong>Results: </strong>In 50 individuals with UCLP;35 (70%) upper lateral incisors were congenitally deficient in the cleft area, while 15 (30%) missing lateral teeth were found in the non-cleft side. In control group, 12 (24%) of 50 patients had congenital lateral incisor deficiency. Congenital deficiency of upper lateral incisor in UCLP;the cleft area was higher than the non-cleft side (p < 0.01). The difference was statistically important when compared with the control group (p < 0.001). In 50 individuals with UCLP;while 27 (54%) of second premolar teeth were congenitally deficient in cleft side, 23 (46%) were missing in non-cleft side. In control group, 18 (36%) congenital second premolar deficiency was detected. However, second premolar congenital deficiency was higher in UCLP group when compared to control group (p < 0.01). <strong>Conclusion:</strong> The deficiency of the lateral incisors in the cleft side is more often congenitally deficient than upper second premolar teeth and this should be considered in the treatment planning from an early age.展开更多

Materials and Methods: Seven patients with repaired cleft lip and palate (CLP) presented with severe maxillary hypoplasia. They were examined initially at T1 predistraction phase. Records taken included radiographs (orthopantograms OPG, lateral cephalometric, posteroanterior). Cephalometric analysis was done to evaluate the upper airway. Mean age is 17 years and the reverse overjet > 6 mm. They underwent maxillary Le Fort I distraction using external rigid distracters (RED). Cephalometric analysis to evaluate the upper airway was repeated at the end of the consolidation phase T2 and twelve months after distractor removal T3. Results: The range of maxillary advancement was between 8 - 15 mm (mean 9 mm). The anteroposterior distance of the superior velopharynx (PPS) and middle velopharynx (SPPS) increased at T2. A small amount of reduction in these values was recorded at T3. The inferior velopharynx (MPS) and the oropharynx (IPS, EPS) showed minimum increase in anteroposterior distance in only two patients at T2 and no change at T3. Conclusion: All seven patients showed clinical improvement in the upper airway and an increase in the upper airway values on lateral cephalometric radiographs.展开更多

Orofacial Clefts (OFCs) are among the causes of perinatal death in Ghana. The children often experience difficulties in swallowing, feeding, and speaking. These children often face problems in cognition, education, and communication. Caregivers’ ignorance of treatment, poverty, and noncompliance with follow-up schedules are obstacles to optimal cleft care. Most studies focus on the incidence of cleft, but not much is known about caregivers’ expectations. Methodology: An exploratory qualitative study design was used for this research between October and November 2020. The study site was the Komfo Anokye Teaching Hospital, (KATH), Kumasi, Ghana. The respondents were recruited from the oral health clinic. Included in the study were all CLP caregivers attending the cleft clinic for the first time. Purposive sampling was used to select fifteen caregivers who met the inclusion criteria. Face-to-face interviews with a semi-structured interview guide were used to collect data. The data were analyzed using NVivo software. Three major themes and six sub-themes emerged from the data analysis using thematic analysis. Ethical clearance was obtained for data collection. Results: Most caregivers were expecting their babies to be operated on, and they were certain that the cleft would be repaired at the end of the treatment, but they were unfamiliar with the process and cost of treatment. Less than half of the caregivers reported that they were oblivious to what to expect the first time visiting but had hopes that the healthcare professionals would be able to close the cleft for their babies. Conclusion: The majority of the caregivers expressed fear and disappointment at the diagnosis of their child. Some caregivers were very scared to the level where they had to hide the babies from the public. Others reported being already in financial difficulties, so their children’s conditions would compound them.展开更多

Material and Method: The study had been conducted on 80 individuals aged between 14 - 17 years having UCLP and BCLP. 40 of the individuals had UCLP, whereas 40 had BCLP. The maxillary dental models taken from patients before the treatment were scanned using Orthomodel Programme (v.1.01, Orthomodel Inc., Istanbul, Turkey) to obtain 3D imagery. Student’s t-test was used in order to assess the data obtained by using SPSS software version 22.0. Results: In BCLP, the average inter-canine distance was 17.44 ± 1.31 mm, the average inter-molar distance was 36.57 ± 1.12 mm, while inter-canine/inter-molar ratio was 0.47. Whereas in UCLP, it was 25.10 ± 0.63 mm, 42.20 ± 0.53 mm and 0.59. The inter-canine distance in UCLP was found to be large enough to be statistically significant (p 0.05), even though there were differences in inter-molar widths. Conclusion: For the stable orthodontic treatment results, one of the most important points is arch form and widths to be coherent with each other. In our study, the increase of inter-canine distance seen in UCLP indicates that in the cleft region, the maxillary arch is inclined over to the back, while the same situation in BCLP suggests that the maxillary segments are collapsed inside. The difference in the arch is highly affected by the primary surgical treatment.展开更多

Patients and methods: 14 adult cleft lip and palate patients with maxillary hypoplasia were evaluated clinically. Dental models and radiographs including (lateral cephalograms and orthopantographs) were obtained at the initial visit and upon completion of the presurgical orthodontic treatment. Patients with occlusal discrepancies larger than 6 mm and severe palatal scaring underwent Distraction osteogenesis (DO) to advance the maxilla. Patients with an occlusal discrepancy of 6 mm or less, underwent traditional orthognathic surgery including le fort I advancement and Bilateral sagittal split osteotomy (BSSO) to seat the mandible in occlusion. Results: Five patients underwent orthognathic surgery. Two of them underwent double jaw surgery. Three underwent single jaw conventional le fort l advancement. Four patients required bone grafting to repair the residual alveolar defect and to augment the midface deficiency. Nine patients with severe maxillary hypoplasia underwent maxillary advancement using distraction osteogenesis. Conclusion: Patients with a severe maxillary hypoplasia of 6 mm or more and excessive palatal scaring are successfully treated with DO. Conventional le fort I is reserved for patients with less severe maxillary hypoplasia. Both techniques gave promising results providing having followed the proper selection criteria.展开更多

In most cases, gastroschisis is isolated. But in some cases, we find malformations, essentially minor and concern gastrointestinal or genitourinary systems. Association with craniofacial congenital midline defects is uncommon. We report 3 cases of association between gastroschisis and cleft lip and palate for the benefit of the scientific community. Two 0-day-old and a 1-day newborns were admitted in our institution for malformation of face and abdominal wall. The physical examination confirmed the association of gastroschisis and cleft lip and palate. The patients underwent primary closure. Other malformations could not be sought until all patients died.展开更多

Patients and Methods: Eight cleft lip and palate patients with maxillary hypoplasia underwent maxillary distraction osteogenesis using external rigid devise. Lateral cephalometric records were obtained before distraction T1 and after completing active distraction T2. After a three month follow up period a final lateral cephalometric record was evaluated T3. Results: The maxilla was significantly advanced as indicated by the increase in maxillary depth angle and effective maxillary length (median difference, 10 mm). The palatal plane angle showed a significant increase (median difference, 5o), showing clockwise rotation. At T3 there was a slight decrease in maxillary depth angle (median difference, 3o). Effective maxillary length decreased significantly at T3 (median difference, 2 mm). The palatal plane angle decreased (median difference, 3o) and almost returned to its original position, showing a counterclockwise rotation. Conclusion: Maxillary advancement using external rigid distractor resulted in clockwise rotation of maxilla with increase in palatal plane angle and slight increase in mandibular plane angle. The amount of maxillary advancement was slightly reduced during follow up and the palatal plane almost returned to its original position. These changes showed good stable clinical results.展开更多

The sample of this retrospective study consisted of 20 UCLP individuals, 12 boys and 8 girls, mean age 10.3 ± 2.4 years at the beginning of orthodontic treatment. All subjects required alveolar bone grafting. CT scans of the cleft area were obtained prior to secondary bone grafting, and were analyzed using Image J. software program. The cleft volume was calculated based on axial cross-sectional CT images by two raters (orthodontist and radiologist) and by the same rater (orthodontist) at two different moments. Linear mixed model, Bland-Altman, Pearson’s and intraclass correlation coefficient (ICC) were used. The mean cleft volume was 7.53 ± 1.55 mm3. The intra- and inter-rater measurements were reproducible (ICC = 0.976 and 0.963, respectively) with no significant difference between them. There were no statistically significant differences in the cleft volume related to age or cleft location. The assessment of cleft volume in UCLP using CT images and a free software program was a reproducible method. There was no significant relation between alveolar defect volume and age or cleft location.展开更多

Out of the one-hundred and thirty million newborns worldwide, 3.6 million identified with a disability, 7.6 million (approximately 5.8%) being born with a congenital anomaly. Additionally, 7.5% of them are registered with having cleft lip palate. In Mongolia, the statistics from the Mongolia Health Department reported that in 2012 cleft lip palate occurred among 1 out of 1072 individuals in Mongolia [1]. Over the years, there have been many measures taken to ameliorate these issues around the world. Recently, the sophisticated three-dimensional ultra-sonography equipment is evaluable in pediatric science. Thanks to this equipment, we are able to detect the orofacial defects and diagnose infants properly in advance. The purpose of this study is to evaluate the lip and palate of a fetus by using three-dimensional ultra-sonography in the second and third trimester of gestational period. Our research aims to detect fetus defects in the early stage of birth and diagnose it in advance [9]. Due to the lack of research on the above-mentioned issues in Mongolia, we decided to conduct this research by using three-dimensional ultra-sonography to detect and diagnose congenital cleft lip palate. By doing this research, we will be able to better assist those suffering from congenital malformation in Mongolia.展开更多

These malformations affect the upper lip, the alveolar bone and the palate. The incidence in Africa ranges from 1/2000 to 1/500 births. Their multidisciplinary management is long and costly. Thus, the help provided by humanitarian organisations during free care campaigns is welcome. Materials and Methods: This is a retrospective descriptive study conducted from August 2014 to July 2016 in the Maxillofacial Surgery and Stomatology Department of the Treichville University Hospital in Abidjan, Côte d’Ivoire. The objective was to describe the epidemiological, clinical and therapeutic aspects of CLPA during a humanitarian campaign for free care. Results: 51 cases of CLPA were operated on. Males were involved in 54.9% of the cases, i.e. a sex ratio of 1.2. The average age of the patients at the time of the operation was 3.44 years with extremes of 3 months and 52 years. Patients with low socioeconomic status represented 84.3% of the cases. Cleft lips (31.4%) and cleft palates (33.33%) predominated. For cleft lips, unilateral forms were the most frequent (73.5%) and the left side was most often affected (59.2%). The most common surgical techniques used were MILLARD cheiloplasty for cleft lips (79.36%) and Dorrance pushback for cleft palates (78.05%). The postoperative course was simple in the majority of cases (80.47%). Patients and/or parents were satisfied with the postoperative results in over 90% of cases. Discussion: Cleft lip and palate are common. Their management by humanitarian missions through mass campaigns allows us to receive a large number of patients affected by this pathology who are treated with a high satisfaction rate. Conclusion: The characteristics of cleft lip and palate in this study are in many respects identical to those described in the literature, but with some differences specific to Africa, notably the absence of antenatal diagnosis and the advanced age at the time of treatment.展开更多

Ultrasonographers involved in the routine 20-wk ultrasound screening could encounter these malformations. The face and palate develop in a very characteristic way. For ultrasonographers involved in screening these patients it is crucial to have a thorough understanding of the embryology of the face. This could help them to make a more accurate diagnosis and save time during the ultrasound. Subsequently, the current postnatal classification will be discussed to facilitate the communication with the CP teams.展开更多

Many epidemiologic studies on this deformity have been conducted worldwide, often producing inconsistent results. This study assessed epidemiology and some genetic aspects of cleft lip and palate in a Chinese sample from the Smile Train Program and to compare with other methodologically sound surveys. Methods The general information, family history, classification of cleft and associated malformations of 8000 CL and CP surgery patients were analyzed. Results Of the 8000 cases, 7812 had complete data. The distribution of cleft types is 17.04% with CP, 23.39% with CL and 59.58% with cleft lip and palate (CLP). Unilateral clefts were more common than bilateral, with unilateral to bilateral ratios being 10.4∶1 for CL, and 3.42∶1 for CLP. The overall male: female ratio was 2.01∶1. Left sided defects were more common than right sided regardless of sex, 1.90∶1 for CL and 1.96∶1 for CLP. CLP and CL were more common in males than in females with sex ratios (SR) of 2.88∶1 and 1.85∶1 respectively, whereas CP was more common in females with SR of 0.76∶1. Associated malformations (2.89%), involved 29 CP cases, 41 CL and 156 CLP. The frequency of associated malformations in CLP (3.35%) was higher than CL (2.24%) and CP (2.22%) (P<0.05). Patients with CP or CLP were born less often in the winter than in the summer (P<0.05). A history of family members having clefts occurred in 6.84% of patients. The proportion of CLP cases (7.56%) was significantly higher than that of CL cases (5.64%) (P<0.05). Conclusions The different types of clefts appeared in the highest proportion in CLP and lowest proportion in CP. Males are more common with CL and CLP and less common with CP. These characteristics are the same as those of other Chinese surveys but different from some European reports.展开更多

The present study was designed to explore if genetic variation in the betaine‐homocysteine methyltransferase (BHMT) gene contributes to NSCL/P. Methods DNA was obtained from 166 individuals with NSCL/P and 285 healthy subjects. Three known single nucleotide polymorphisms (SNPs) present in the BHMT gene (rs651852, rs3797546, and rs3733890) were investigated by real‐time PCR‐based TaqMan genotyping. Results Neither allelic nor genotypic association was found between NSCL/P and SNPs rs651852 and rs3733890. SNP rs3797546 did not show allelic association with NSCL/P; however, a higher proportion of NSCL/P patients carry the CC genotype compared with the TT+CT genotype (P=0.020, OR=2.10, 95% CI=1.11‐3.95). Conclusion Our study suggests that polymorphism rs3797546 in the BHMT gene may confer genetic risk of NSCL/P in a recessive manner.展开更多
文摘Various surgical techniques and approaches have been described to repair cleft nose deformities. It is necessary to consider that since it is a congenital deformity, surgical management must consider the patient’s growth process, as well as the healing itself from the surgery. The present study aims to evaluate an alternative solution to secondary rhinology, aesthetic, and functional alterations to unilateral or bilateral cleft lift palate to minimize deformities and ensure good results. 11 patients were studied between 1995 to 2002, ten male and one female. In 8 cases, the patients had a history of cleft lip and palate on the left side, 2 patients with cleft lift palate on the right, and 1 patient with bilateral cleft lip and palate. 100% of the patients increased their naso-labial angle. This improved their appearance and structure, starting from a preoperative arithmetic mean of 39 degrees to a postoperative arithmetic mean of 96 degrees. Such intervention increased the naso-labial angle by 57 degrees. At the base of the nose, it was possible to improve the inclination of the alar line (line B) in 10 of the cases with a variation of 2 to 3 mm in relation to the perpendicular line A and only one case remained with the same inclination.

The difference in the arch is highly affected by the primary surgical treatment.
文摘Objectives: We report our experience and the protocol we used in managing maxillary hypoplasia in cleft lip and palate patients. Patients and methods: 14 adult cleft lip and palate patients with maxillary hypoplasia were evaluated clinically. Dental models and radiographs including (lateral cephalograms and orthopantographs) were obtained at the initial visit and upon completion of the presurgical orthodontic treatment. Patients with occlusal discrepancies larger than 6 mm and severe palatal scaring underwent Distraction osteogenesis (DO) to advance the maxilla. Patients with an occlusal discrepancy of 6 mm or less, underwent traditional orthognathic surgery including le fort I advancement and Bilateral sagittal split osteotomy (BSSO) to seat the mandible in occlusion. Results: Five patients underwent orthognathic surgery. Two of them underwent double jaw surgery. Three underwent single jaw conventional le fort l advancement. Four patients required bone grafting to repair the residual alveolar defect and to augment the midface deficiency. Nine patients with severe maxillary hypoplasia underwent maxillary advancement using distraction osteogenesis. Conclusion: Patients with a severe maxillary hypoplasia of 6 mm or more and excessive palatal scaring are successfully treated with DO. Conventional le fort I is reserved for patients with less severe maxillary hypoplasia. Both techniques gave promising results providing having followed the proper selection criteria.
文摘Gastroschisis is a malformation of the abdominal wall like omphalocele. In most cases, gastroschisis is isolated. But in some cases, we find malformations, essentially minor and concern gastrointestinal or genitourinary systems. Association with craniofacial congenital midline defects is uncommon. We report 3 cases of association between gastroschisis and cleft lip and palate for the benefit of the scientific community. Two 0-day-old and a 1-day newborns were admitted in our institution for malformation of face and abdominal wall. The physical examination confirmed the association of gastroschisis and cleft lip and palate. The patients underwent primary closure. Other malformations could not be sought until all patients died.
文摘Purpose: To evaluate the skeletal changes associated with maxillary advancement using the external rigid distractor in cleft lip and palate patients after distraction and to assess the stability of these changes. Patients and Methods: Eight cleft lip and palate patients with maxillary hypoplasia underwent maxillary distraction osteogenesis using external rigid devise. Lateral cephalometric records were obtained before distraction T1 and after completing active distraction T2. After a three month follow up period a final lateral cephalometric record was evaluated T3. Results: The maxilla was significantly advanced as indicated by the increase in maxillary depth angle and effective maxillary length (median difference, 10 mm). The palatal plane angle showed a significant increase (median difference, 5o), showing clockwise rotation. At T3 there was a slight decrease in maxillary depth angle (median difference, 3o). Effective maxillary length decreased significantly at T3 (median difference, 2 mm). The palatal plane angle decreased (median difference, 3o) and almost returned to its original position, showing a counterclockwise rotation. Conclusion: Maxillary advancement using external rigid distractor resulted in clockwise rotation of maxilla with increase in palatal plane angle and slight increase in mandibular plane angle. The amount of maxillary advancement was slightly reduced during follow up and the palatal plane almost returned to its original position. These changes showed good stable clinical results.
文摘The purpose of this study was to assess the alveolar defect volume in unilateral cleft lip and palate (UCLP) subjects using computed tomography (CT) and a free software program to evaluate the intra- and inter-rater measurements, and to compare the cleft volume between age and affected side. The sample of this retrospective study consisted of 20 UCLP individuals, 12 boys and 8 girls, mean age 10.3 ± 2.4 years at the beginning of orthodontic treatment. All subjects required alveolar bone grafting. CT scans of the cleft area were obtained prior to secondary bone grafting, and were analyzed using Image J. software program. The cleft volume was calculated based on axial cross-sectional CT images by two raters (orthodontist and radiologist) and by the same rater (orthodontist) at two different moments. Linear mixed model, Bland-Altman, Pearson’s and intraclass correlation coefficient (ICC) were used. The mean cleft volume was 7.53 ± 1.55 mm3. The intra- and inter-rater measurements were reproducible (ICC = 0.976 and 0.963, respectively) with no significant difference between them. There were no statistically significant differences in the cleft volume related to age or cleft location. The assessment of cleft volume in UCLP using CT images and a free software program was a reproducible method. There was no significant relation between alveolar defect volume and age or cleft location.
文摘Congenital cleft lip palate occurs heterogeneously worldwide. Out of the one-hundred and thirty million newborns worldwide, 3.6 million identified with a disability, 7.6 million (approximately 5.8%) being born with a congenital anomaly. Additionally, 7.5% of them are registered with having cleft lip palate. In Mongolia, the statistics from the Mongolia Health Department reported that in 2012 cleft lip palate occurred among 1 out of 1072 individuals in Mongolia [1]. Over the years, there have been many measures taken to ameliorate these issues around the world. Recently, the sophisticated three-dimensional ultra-sonography equipment is evaluable in pediatric science. Thanks to this equipment, we are able to detect the orofacial defects and diagnose infants properly in advance. The purpose of this study is to evaluate the lip and palate of a fetus by using three-dimensional ultra-sonography in the second and third trimester of gestational period. Our research aims to detect fetus defects in the early stage of birth and diagnose it in advance [9]. Due to the lack of research on the above-mentioned issues in Mongolia, we decided to conduct this research by using three-dimensional ultra-sonography to detect and diagnose congenital cleft lip palate. By doing this research, we will be able to better assist those suffering from congenital malformation in Mongolia.
文摘Introduction: Cleft lip, palate and alveolar (CLPA) are congenital malformations of the face due to a defect in the fusion of embryonic buds during the first weeks of embryogenesis. These malformations affect the upper lip, the alveolar bone and the palate. The incidence in Africa ranges from 1/2000 to 1/500 births. Their multidisciplinary management is long and costly. Thus, the help provided by humanitarian organisations during free care campaigns is welcome. Materials and Methods: This is a retrospective descriptive study conducted from August 2014 to July 2016 in the Maxillofacial Surgery and Stomatology Department of the Treichville University Hospital in Abidjan, Côte d’Ivoire. The objective was to describe the epidemiological, clinical and therapeutic aspects of CLPA during a humanitarian campaign for free care. Results: 51 cases of CLPA were operated on. Males were involved in 54.9% of the cases, i.e. a sex ratio of 1.2. The average age of the patients at the time of the operation was 3.44 years with extremes of 3 months and 52 years. Patients with low socioeconomic status represented 84.3% of the cases. Cleft lips (31.4%) and cleft palates (33.33%) predominated. For cleft lips, unilateral forms were the most frequent (73.5%) and the left side was most often affected (59.2%). The most common surgical techniques used were MILLARD cheiloplasty for cleft lips (79.36%) and Dorrance pushback for cleft palates (78.05%). The postoperative course was simple in the majority of cases (80.47%). Patients and/or parents were satisfied with the postoperative results in over 90% of cases. Discussion: Cleft lip and palate are common. Their management by humanitarian missions through mass campaigns allows us to receive a large number of patients affected by this pathology who are treated with a high satisfaction rate. Conclusion: The characteristics of cleft lip and palate in this study are in many respects identical to those described in the literature, but with some differences specific to Africa, notably the absence of antenatal diagnosis and the advanced age at the time of treatment.
文摘Importance:Cleft lip and palate(CLP)is globally among the most common childhood malformations.This disorder impacts childhood development,including speech and language,and affects children worldwide.Objective:To analyze child development skills(adaptive fine motor,gross motor,personal-social,and language)in preschool children with isolated CLP compared with children without this malformation.Methods:The participants included an experimental group of 27 children with isolated CLP and a comparison group of 27 children without CLP aged between 48 and 59 months.The groups were evaluated using two instruments:the Denver Developmental Screening Test II(DDST-II)and the Avaliapao do Desenvolvimento da Linguagem(ADL-Language Development Assessment).Data were analyzed by descriptive and inductive analyses,using the Student’s Mest and the Mann-Whitney test,at a significance level of P<0.05.Results:All children in the comparison group performed within normal standards for their age range in the DDST-II and the ADL.The worst performance in the experimental group was observed in language skills,followed,in declining order,by adaptive fine motor,personal-social,and gross motor as measured by the DDST-II.Children with isolated CLP also performed poorly in receptive,expressive,and global language in the ADL.No statistically significant differences were observed in the experimental group’s scores for the ADL and the DDST-II.Interpretation:Developmental skill levels were below expectations for children of this age with isolated CLP.

文摘Cleft lip and/or palate(CLP)are the most common craniofacial malformations in humans.Speech problems often persist even after cleft repair,such that follow-up articulation training is usually required.However,the neural mechanism behind effective articulation training remains largely unknown.We used fMRI to investigate the differences in brain activation,functional connectivity,and effective connectivity across CLP patients with and without articulation training and matched normal participants.We found that training promoted task-related brain activation among the articulation-related brain networks,as well as the global attributes and nodal efficiency in the functional-connectivity-based graph of the network.Our results reveal the neural correlates of effective articulation training in CLP patients,and this could contribute to the future improvement of the post-repair articulation training program.

文摘This case report aimed to present the course of surgically combined comprehensive orthodontic treatment of a male adult with cleft lip and palate,showing a left alveolar cleft,lateral deviation of the major segment of the maxilla,and palatal transposition of the lateral incisor.Preoperatively,the midline of the upper central incisors was shifted by 7.0 mm to the right,the right lateral incisor showed palatal transposition,and the residual alveolar cleft was 6.5 mm.Segmental Le Fort I osteotomy of the major segment,and simultaneous bone grafting into the extended alveolar bone and former cleft region were performed at 18 years and 4 months of age.Thus,midline correction,alignment of the right lateral incisor,and cleft closure were achieved;no further prosthetic treatment was required.
文摘Cleft lip with or without cleft palate(CP) is one of the most common congenital malformations. Ultrasonographers involved in the routine 20-wk ultrasound screening could encounter these malformations. The face and palate develop in a very characteristic way. For ultrasonographers involved in screening these patients it is crucial to have a thorough understanding of the embryology of the face. This could help them to make a more accurate diagnosis and save time during the ultrasound. Subsequently, the current postnatal classification will be discussed to facilitate the communication with the CP teams.
文摘Background Cleft lip (CL) and cleft palate (CP) are two of the most frequent congenital malformations. Many epidemiologic studies on this deformity have been conducted worldwide, often producing inconsistent results. This study assessed epidemiology and some genetic aspects of cleft lip and palate in a Chinese sample from the Smile Train Program and to compare with other methodologically sound surveys. Methods The general information, family history, classification of cleft and associated malformations of 8000 CL and CP surgery patients were analyzed. Results Of the 8000 cases, 7812 had complete data. The distribution of cleft types is 17.04% with CP, 23.39% with CL and 59.58% with cleft lip and palate (CLP). Unilateral clefts were more common than bilateral, with unilateral to bilateral ratios being 10.4∶1 for CL, and 3.42∶1 for CLP. The overall male: female ratio was 2.01∶1. Left sided defects were more common than right sided regardless of sex, 1.90∶1 for CL and 1.96∶1 for CLP. CLP and CL were more common in males than in females with sex ratios (SR) of 2.88∶1 and 1.85∶1 respectively, whereas CP was more common in females with SR of 0.76∶1. Associated malformations (2.89%), involved 29 CP cases, 41 CL and 156 CLP. The frequency of associated malformations in CLP (3.35%) was higher than CL (2.24%) and CP (2.22%) (P<0.05). Patients with CP or CLP were born less often in the winter than in the summer (P<0.05). A history of family members having clefts occurred in 6.84% of patients. The proportion of CLP cases (7.56%) was significantly higher than that of CL cases (5.64%) (P<0.05). Conclusions The different types of clefts appeared in the highest proportion in CLP and lowest proportion in CP. Males are more common with CL and CLP and less common with CP. These characteristics are the same as those of other Chinese surveys but different from some European reports.

文摘Objective Convincing evidence suggests a link between increased risk of nonsyndromic cleft lip with or without cleft palate (NSCL/P) and low intake of folic acid by the mother during pregnancy. The present study was designed to explore if genetic variation in the betaine‐homocysteine methyltransferase (BHMT) gene contributes to NSCL/P. Methods DNA was obtained from 166 individuals with NSCL/P and 285 healthy subjects. Three known single nucleotide polymorphisms (SNPs) present in the BHMT gene (rs651852, rs3797546, and rs3733890) were investigated by real‐time PCR‐based TaqMan genotyping. Results Neither allelic nor genotypic association was found between NSCL/P and SNPs rs651852 and rs3733890. SNP rs3797546 did not show allelic association with NSCL/P; however, a higher proportion of NSCL/P patients carry the CC genotype compared with the TT+CT genotype (P=0.020, OR=2.10, 95% CI=1.11‐3.95). Conclusion Our study suggests that polymorphism rs3797546 in the BHMT gene may confer genetic risk of NSCL/P in a recessive manner.
