Association Between Maxillary Segmentation and Perioperative Complications in Le Fort I Osteotomy.

The Le Fort I osteotomy is used to reposition the maxilla to correct numerous maxillofacial and occlusal deformities. The aim of this study was to delineate perioperative complication rates associated with Le Fort I osteotomy and determine whether the number of maxillary segments or bone grafting yielded increased complication rates. Patients undergoing Le Fort I osteotomy from 2012 to 2019 were identified from the multi-institution "National Surgical Quality Improvement Program" database using Current Procedure Terminology codes. The predictor variables of interest included maxillary segmentation defined as 1, 2, or 2 pieces and the presence or absence of bone graft. Perioperative complications were collected as the primary outcome variable, including superficial and deep space infections, wound dehiscence, airway complication, peripheral nerve injury, and hemorrhage. The secondary outcome variables included readmission and reoperation rate within the 30-day postoperative period. Complication rates were compared using multivariate analysis across groups stratified by the number of maxillary segments and inclusion of bone grafting. Of the 532 patients that met the inclusion criteria, 333 (63%) underwent 1-piece, 114 (21%) 2-piece, and 85 (16%) 2-piece Le Fort I osteotomy procedures. A total of 48 patients exhibited complications (9%), with hemorrhage (2.3%) being the most common complication observed. The number of maxillary segments was not a significant predictor of perioperative complications ( P = 0.948) nor was the use of bone grafting ( P = 0.279). Copyright © 2023 by Mutaz B. Habal, MD.
