New Anatomical Point of View of Alar Cartilage in Cleft Lip Nose Deformity and the Effects of Removal of Intercartilagenous Soft Tissue on Relocaton of Alar Cartilage

Abstract

Previous anatomic concepts in cleft lip nose deformity have following characteristics: 1. Obtuse angle between medial and lateral crus in affected alar cartilage; and 2, Cleft side alar cartilage is hypoplastic. The purpose of this study was to review the anatomy of alar cartilage in cleft lip nose deformity and to find out the effects of removal of intercartilagenous soft tissue on the effects of removal of intercartilagenous soft tissue on relocation of alar cartilage. There were 97 cleft lip nose corrections from Oct. 1996 to March When the affected alar cartilage was dissected, redundant intercartilagenous fibro-fatty tissue was found. After removing this redundant soft tissue, we found that the cleft side alar cartilage was better adjusted to the normal position. In addition, the plicavestibularis was more improved. Alar cartilage suture fixation was subsequently performed. Alar cartilage suture fixation was subsequently performed. After this procedure, we found that subsequently performed. After this procedure, we found that the affected side of alar cartilage was more normally positioned than before. The summary of the author's view on affected alar cartilage is as follows: 1. An acute angle between the medial and lateral crus was noted in affected alar cartilage; 2. Redundant intercartilagenous fibro-fatty tissue was present in cleft lip nose deformity;3.The terminal portion of the lateral crus of alar cartilage makes a plica vestibularis in the cleft side; 4. The position of the medial crus of alar cartilage was lower in the cleft side with the lateral crus was lower and cephalic in the cleft side; 5. The cleft side of alar cartilage is not hypoplastic.
