腭侧入路改良 Le Fort Ⅰ型截骨术矫正唇腭裂继发上颌骨发育不足的临床初步应用
Transpalatal modified Le Fort Ⅰ osteotomy for correction of maxillary hypoplasia in cleft lip and palate patients:a preliminary clinical application
摘要
Abstract
Objective:To evaluate the surgical corrective results of maxillary hypoplasia in patients with cleft lip and palate withtranspalatal modified Le Fort Ⅰ osteotomy.Methods:In the study,1 1 patients (4 women,and 7 men)with maxillary hypoplasia secondary to cleft lip and palate underwent transpalatal modified Le Fort Ⅰ osteotomy at Peking University School of Stomatology from Jan.201 2 to Dec.201 3, with the mean age of 21 years (from 1 8 to 27 years),Bilateral sagittal split ramus osteotomy (BSSRO) and genioplasty were performed simultaneously in 9 of them for better appearance and functional occlu-sion.Lateral cephalometric radiographs were taken and traced before surgery,immediately after surgery and 6 months after surgery.The position of subspinale (A)on horizontal direction,the angle of sella-na-sion-subsipmale (SNA)and the angle of sella-nasion-supramental (SNB)were collected and analyzed to evaluate the results.Results:All the patients were uneventful with transpalatal modified Le Fort Ⅰosteotomy.All of them had a better profile and a satisfactory occlusionafter operation.The position of A was moved forward (6.6 ±1 .1 )mm on average in horizontal direction when surgery was completed,and maintained (6.0 ±1 .2)mm on average 6 months after surgery.The average of SNA was 75.9°±2.8° before surgery,81 .6°±8.6°immediately after surgery,and maintained 81 .0°±2.6°6 months after sur-gery.The average of SNB was 82.6°±3.7°before surgery,78.0°±2.4°immediately after surgery,and maintained 78.5°±2.4°6 months after surgery.Conclusion:The maxillary hypoplasia in cleft lip and palate patients can be successfully corrected with transpalatal modified Le Fort Ⅰ osteotomy and the func-tional occlusion can be achieved simultaneously.The effect of deformity correction was satisfactory. Transpalatal modified Le Fort Ⅰ osteotomy can move maxilla more sufficiently,especially applicable for the patient with severe palatal scars preoperatively.关键词
