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.

The purpose of this study is to evaluate the relationship of the factors which could be influenced by orthognathic surgery especillay SSRO. We measured the amounts of the maximum opening, lateral movements, maximum velocity and pattern of mandibular path during the opening and closing of mandible at the following times ; preoperative, 1 month after operation, 6 months after operation respectively using MKG. And the results were compared according to the categorized subgroups. Following results were obtained : 1. The change of the amounts of mandibular lateral movement and maximum opening velocity were statistically different between male and female (p<0.05), but the others were not. 2. According to the method of operation, there was no difference in the change of the mandibular movements between the group of SSRO and SSRO plus LeFort I osteotomy (p>0.05). 3. According to the amounts of mandibular movement, the recovery of left lateral movement of the group of 6~10mm was better than the other groups (p<0.05). 4. In the frontal pattern of the opening and closing of the mandible, the complex deflected type (F5), simple deflected type (F4), complex deviated type (F3), simple deviated type (F2), straight type (F1) were obtained in order at the time of preoperative, simple deflected type, simple deviated type, complex deviated type, straight type, complex deflected type in order at the time of 1 month after surgery, and the result at the time of 6 months after surgery was the same with that of the time of preoperative. In the sagittal pattern, non-coincident type (S2) was predominant at the time of preoperative, and coincident type (S1) was predominant at the time of 1 month after surgery. After 6 months, the result was also the same with that of the preoperative in sagittal pattern. 5. There was not a statistical difference in the change of the mandibular movement between group of presence of the preoperative TMJ symptoms and non-presence group (p>0.05). 6. There was not a statistical difference in the change of the mandibular movement between repositioning device applied group and non-applied group (p>0.05). 7. Sixty three percents of the patients who had preoperative TMJ symptoms were improved after surgery and preoperative TMJ symptoms were more improved after operation in the repositioning device non-applied group statistically (p<0.05).
