We aim to report our experience in the practice of this surgical technique. <strong>Patients and method:</strong> This was a prospective and descriptive study of penile skin flap urethroplasty indicated for urethral stenosis between January 2014 and December 2019. <strong>Results:</strong> A total of 21 penile skin flap urethroplasties for urethral stenosis were performed. The average age was 38.6 years old. The stenosis was of sclero-inflammatory origin in 15 cases (71.43%). It was of bulbo-perineal, penile, and penile-bulbar topography in about a third each. A history of urethral surgery was reported in 80.95% of the cases. The average length of the stenosis was 6.8 cm. Mundy circular skin flap urethroplasty about 15 cases (71.43%), and Quartey rectangular skin penile flap urethroplasty about 6 cases (28.57%) were the surgical techniques performed. The postoperative follow-up was favorable in 19 cases (90.48%). Two cases of urethral fistula (9.52%) underwent the 2<sup>nd</sup> urethroplasty. Urination at 1 year was satisfactory. No relapse has been reported to date. However, 4 patients (19.04%) reported asthenic ejaculation, and 1 patient (4.76%) a marked decrease in sexual pleasure. <strong>Conclusion:</strong> This surgical technique is effective in terms of voiding when the surgical indications are well chosen. The sexual aspect must be taken into account and the intervention only offered to those who really need it.展开更多

Yet, despite the excellent reported results, the use of DF has not been widespread. Some factors for the less widespread use of DF have been, concern about diaphragmatic function, hesitation to use such a vital muscle for reconstructive purposes, and most importantly, the technical aspects for the preparation of the flap. Methods: Using a cadaveric model, the vascular anatomy of the diaphragm and the steps for the preparation of the DF was defined and illustrated for both the right and left hemidiaphragm. Results: No perioperative mortality with the use of DF has been recorded. Function of the native diaphragm has not been impaired. Bronchopleural fistulas and pericardial defects have healed in all instances. Excellent repair has been achieved in all patients with esophageal lesions. The disruption of the repaired native diaphragm and visceral herniation has been reported but it has been attributed to the learning curve and the technique of repair. Conclusion: With a better understanding of the vascular anatomy of the diaphragm and a formal methodical approach to harvesting the DF, more surgeons will be encouraged to use DF with excellent results.展开更多

Soft tissue reconstruction of the abdominal wall is perf...Large abdominal cutaneous defects may occur in association with complex ventral hernias, trauma, tumor resection, necrotizing infections or septic evisceration. Soft tissue reconstruction of the abdominal wall is performed when there is insufficient adipocutaneous tissue to permit standard, primary closure. A number of reconstructive techniques are available, the choice of which is based on a number of factors, including the size and location of the defect, etiology, and timing of closure. In general, local fasciocutaneous advancement flaps and adjacent tissue rearrangement are the workhorse techniques, followed by regional myocutaneous flaps and free tissue transfers for the most complex and extensive of defects. Herein, we describe our approach to abdominal soft tissue reconstruction, indications, technical nuances, and management of complications.展开更多

The reader will be exposed to the step by step approach to achieving cosmetic enhancement and functional rehabilitation of advanced facial burns. The"keystone"of the autogenous reconstruction is the pre-patterned, sculpted microvascular free flap designed to fit like the"piece of a puzzle"into the aesthetic units of the face to replace disfiguring burn scars. Aggressive intraoperative"sculpting"is employed both"in situ"at the donor site and during the flap transfer to simulate the normal facial contours and planes. Comparisons of the author's approach are made to the whole spectrum of reconstructive modalities ranging from conventional grafting to expanded pre-fabricated flaps and even to CTA face transplants;advantages/disadvantages of each are discussed. The pre-patterned, sculpted microvascular (MV) free flap offers the benefit of a single-stage transfer of composite skin/soft tissue hiding the seams at the junction of facial planes. When harvested from distant donor sites, the donor deformities can easily be concealed. The MV free tissue transfer offers the substrate that can be sculpted into nuanced facial components as well as the"palette"upon which the face can be painted with creative camouflage makeup. The soft contour and texture of the autogenous patterned transfers translates into a"natural"facial appearance while preserving fluid motions of facial expression.展开更多

文摘<strong>Introduction:</strong> Penile skin flap urethroplasty is a technique for replacing or enlarging an obstructed urethra. We aim to report our experience in the practice of this surgical technique. <strong>Patients and method:</strong> This was a prospective and descriptive study of penile skin flap urethroplasty indicated for urethral stenosis between January 2014 and December 2019. <strong>Results:</strong> A total of 21 penile skin flap urethroplasties for urethral stenosis were performed. The average age was 38.6 years old. The stenosis was of sclero-inflammatory origin in 15 cases (71.43%). It was of bulbo-perineal, penile, and penile-bulbar topography in about a third each. A history of urethral surgery was reported in 80.95% of the cases. The average length of the stenosis was 6.8 cm. Mundy circular skin flap urethroplasty about 15 cases (71.43%), and Quartey rectangular skin penile flap urethroplasty about 6 cases (28.57%) were the surgical techniques performed. The postoperative follow-up was favorable in 19 cases (90.48%). Two cases of urethral fistula (9.52%) underwent the 2<sup>nd</sup> urethroplasty. Urination at 1 year was satisfactory. No relapse has been reported to date. However, 4 patients (19.04%) reported asthenic ejaculation, and 1 patient (4.76%) a marked decrease in sexual pleasure. <strong>Conclusion:</strong> This surgical technique is effective in terms of voiding when the surgical indications are well chosen.

文摘BACKGROUND Thumb polydactyly is one of the most common congenital hand deformities,and the Bilhaut-Cloquet procedure or a modified one is often used.However,controversy remains over the rare instances in which both thumbs are not of similar length or far apart in distance.AIM To evaluate the clinical outcomes of pedicle complex tissue flap transfer in the treatment of duplicated thumbs with unequal size.METHODS From January 2014 to December 2020,15 patients underwent duplicated thumb reconstruction by pedicle complex tissue flap transfer at our hand surgery center.The technique was used when it was necessary to combine different tissues from both severed and preserved thumbs that were not of similar length or far apart in distance.Subjective parents’evaluations and functional outcomes(ALURRA and TATA criteria)were obtained.The alignment deviation,instability,range of motion(percent of opposite thumb)of the interphalangeal and metacarpophalangeal joints,and the aesthetic aspects,including circumference,length,nail size,and nail deformity,were used to assess the clinical outcomes.RESULTS The average age of patients at the time of surgery was 13 mo,and the mean final follow-up occurred at 42 mo.An appropriate volume with a stable joint and good appearance was obtained in 14 reconstructed thumbs.An unstable interphalangeal joint occurred in one thumb.The flexion-extension arc at the metacarpophalangeal joint was good,while that at the interphalangeal joint was poor.Most of the parents were satisfied with the cosmetic and functional results of the reconstructed thumbs.The mean ALURRA score was 21.8(range:20-24),and the Tada score was 6.9(range:5-8).Compared with the non-operated side,the length of the operated thumb was approximately 95%,the girth was 89%,and the nail width was 82.9%.The mean ranges of motion were 62.1%of that of the unaffected thumb in the interphalangeal joint and 78.3%in the metacarpophalangeal joint.CONCLUSION Harvesting a pedicle flap from a severed thumb is a safe and reliable procedure.Defects of the preserved thumb,such as the skin,nail,and bone,can be effectively restored using the complex tissue flap.
文摘Background: The use of a vascularized pedicle flap of diaphragmatic muscle (DF) for reconstructive procedures in the chest has many advantages. Yet, despite the excellent reported results, the use of DF has not been widespread. Some factors for the less widespread use of DF have been, concern about diaphragmatic function, hesitation to use such a vital muscle for reconstructive purposes, and most importantly, the technical aspects for the preparation of the flap. Methods: Using a cadaveric model, the vascular anatomy of the diaphragm and the steps for the preparation of the DF was defined and illustrated for both the right and left hemidiaphragm. Results: No perioperative mortality with the use of DF has been recorded. Function of the native diaphragm has not been impaired. Bronchopleural fistulas and pericardial defects have healed in all instances. Excellent repair has been achieved in all patients with esophageal lesions. The disruption of the repaired native diaphragm and visceral herniation has been reported but it has been attributed to the learning curve and the technique of repair. Conclusion: With a better understanding of the vascular anatomy of the diaphragm and a formal methodical approach to harvesting the DF, more surgeons will be encouraged to use DF with excellent results.
文摘Objective To report the treatment of perineal hypospadias with one - stage urethroplaty with circumferential vascular pedicle preputial island flap. Methods A circumferential incision was made proximal to the cprona and the urethral plate to correct chordee. A U - shaped skin incision was then made surrounding the meatus。
文摘Objective To report evaluat of division region of abdominal wall large defect after tumors resection and repair methods by tissue flaps with pedicle. Methods Form October 1992 to September 2001, 8 cases large abdominal wall defect after malignant tumors resection(10 × 10 cm-32 cm×32 cm) were reviewed. The defectcontributed:Ⅰ region, 2 cases; twin-Ⅱ region, 2; Ⅲ region, 2; Ⅰ and Ⅱ region of one side, 1 and total abdominal wall,one case, The tissue flaps of transposition included: gracilis myocutaneous flaps, 4; retus abdominal myocutaneous flaps, 2; external abdominal obligue musculo-fascia flaps, 2; latissimus dorsi muscle, tensor fasciae latae muscle and retus femoris muscle flaps each, 1. One patient used MycroMesh also. Results In the course of peroperation, the incisions of 8 cases healed in first time; total tissue flaps survived and all pateints started exercise left the bed in 3 weeks. All 8 patients were followed up average of 2 years and 5 months: the success rate of reconstruction
文摘To report a method of repair facial skin defects with a skin flap of SMAS pedicle.Methods According to the size of defect of skin,design a skin flap with SMAS pedicle for repair of defect.Results The method has been successfully applied for skin defects of eyelid and lip in 14 cases with satisfied results.The area of the largest flap was 5 cm×3 cm.Conclusion Repairing facial defects such as eyelid skin defect or lip skin defect with skin flap of SMAS pedicle is a very good method.The flap has a good blood supporting and satisfactory color and flexibility.5 refs,6 figs.
文摘Objective:To review our experience with infrahyoid myocutaneous flap in reconstruction after oral cancer resection.Methods:Chart reviews were completed for all patients who underwent oral reconstruction with an infrahyoid myocutaneous flap by a single surgeon in the Department of Otolaryngology at Chonburi Cancer Hospital from 2011 to 2017.Characteristics of the patients and postoperative complications were analyzed.Results:Of the 34 patients in the study,10(29.4%)developed partial flap loss and 1(2.9%)developed total flap loss.All cases of partial flap loss resolved with conservative treatment.Apparent cancer involvement of a cervical lymph node was significantly associated with flap failure(odds ratio:5.0,95%CI:1.03e24.28).Conclusions:The infrahyoid myocutaneous flap is a fairly reliable reconstruction method.The flap should be performed with caution in cases with gross lymph node involvement.
文摘Large abdominal cutaneous defects may occur in association with complex ventral hernias, trauma, tumor resection, necrotizing infections or septic evisceration. Soft tissue reconstruction of the abdominal wall is performed when there is insufficient adipocutaneous tissue to permit standard, primary closure. A number of reconstructive techniques are available, the choice of which is based on a number of factors, including the size and location of the defect, etiology, and timing of closure. In general, local fasciocutaneous advancement flaps and adjacent tissue rearrangement are the workhorse techniques, followed by regional myocutaneous flaps and free tissue transfers for the most complex and extensive of defects. Herein, we describe our approach to abdominal soft tissue reconstruction, indications, technical nuances, and management of complications.
文摘The author reviews his pioneering work in aesthetic restoration of the severely disfigured burn face first introduced in 1995 and refined over the past two decades. The reader will be exposed to the step by step approach to achieving cosmetic enhancement and functional rehabilitation of advanced facial burns. The"keystone"of the autogenous reconstruction is the pre-patterned, sculpted microvascular free flap designed to fit like the"piece of a puzzle"into the aesthetic units of the face to replace disfiguring burn scars. Aggressive intraoperative"sculpting"is employed both"in situ"at the donor site and during the flap transfer to simulate the normal facial contours and planes. Comparisons of the author's approach are made to the whole spectrum of reconstructive modalities ranging from conventional grafting to expanded pre-fabricated flaps and even to CTA face transplants;advantages/disadvantages of each are discussed. The pre-patterned, sculpted microvascular (MV) free flap offers the benefit of a single-stage transfer of composite skin/soft tissue hiding the seams at the junction of facial planes. When harvested from distant donor sites, the donor deformities can easily be concealed. The MV free tissue transfer offers the substrate that can be sculpted into nuanced facial components as well as the"palette"upon which the face can be painted with creative camouflage makeup. The soft contour and texture of the autogenous patterned transfers translates into a"natural"facial appearance while preserving fluid motions of facial expression.
