Abstract

The purpose of this article is to investigate the complications associated with mandibulotomies and analyze contributing factors. A total of 103 patients, who had undergone a mandibulotomy for tumors of the oral cavity or oropharynx, were identified and their hospital records, clinical charts, and radiographs retrospectively reviewed. Variables associated with mandibulotomy complications (osteotomy type, osteotomy site, tooth extraction, fixation method, radiation, and chemotherapy) were classified and statistically analyzed. Various complications were encountered in 19 (18.4%) patients, and were classified into 2 categories: intraoperative and postoperative complications. Paramedian (42.7%) stair-step (86.4%) osteotomies had been frequently used. Rigid fixation using one monocortical plate, one bicortical plate, and screws (MCP + BCP [46.6%]) was the main fixation method and showed statistical significance in the complications of mandibulotomy (P < .05). Five (71.4%) out of 7 patients who received preoperative radiotherapy developed postoperative complications, and 3 (60%) out of 5 patients who received preoperative chemotherapy developed complications. Among the complications, nonunion was observed in 7 (6.7%) patients and os...Continue Reading
