摘要
目的探索单侧唇裂鼻畸形的发生机理和寻找行之有效的手术方法。方法解剖20具成人尸体、1具单侧唇裂胎儿标本和24例临床患者的术中观察,进行对比研究。结果发现外鼻下端存在鼻翼软骨纤维环和鼻翼软骨肌肉环两个维持鼻孔与鼻下部形态的重要解剖结构。而单侧唇裂患者裂侧的这两个环状结构在裂隙处断裂或不全。据此,笔者设计了对裂侧鼻翼软骨环状结构重建的手术修复方法。结论鼻翼软骨纤维环和鼻翼软骨肌肉环是维持外鼻下端形态和鼻孔对称的重要解剖结构。此环状结构的破坏是导致外鼻形态畸形的重要因素之一。在单侧唇裂鼻畸形矫正手术中,重建完善的鼻翼软骨环状结构对形态改善具有重要的临床意义。
Objective To explore the possible pathogenesis and to look for effective reconstructive procedures of unilateral cleft lip nose.Methods The author has had a detailed comparative study by com- paring the cartilaginous skeleton of 20 normal cadaver specimens with that of one unilateral cleft lip still- born,as well as intraoperative findings of 24 clinical patients.Results There are two alar cartilaginous rings,namely alar cartilaginous fibrous ring and alar cartilaginous muscular ring,in external nose.Both rings are hypoplastic in the cleft lip patients.According to the findings,the author designed and applied a new operation procedure to reconstruct alar cartilage ring for 24 patients from 1994 to 1997.An accept- able short-term results were found.Conclusion Alar cartilaginous fibrous ring and alar cartilaginous mus- cular ring are very important anatomic structures to maintain the shape of the lower part of the nose.Hy- poplasia of these rings is an important factor leading to deformities of the nose.It is very important to re- construct alar cartilage ring for the patients with unilateral cleft lip nose.
