Abstract
Objective: Mandibulotomy is an important surgical approach to oral cavity and oropharynx. The objective of this study was to evaluate the related complications of 2 common mandibulotomies: midline (osteotomy between 2 central incisors) and paramidline (osteotomy between lateral incisor and canine). Study Design: Ninety-six patients who had cancer in the oral cavity or oropharynx had preoperative evaluation of the mandible with panoramic films. Among them, 42 patients underwent mandibulotomies: midline for 19 patients and paramidline for 23. Results: Twenty (47.6%) of 42 patients had mandibulotomy-related complications, including 9 (21.4%) minor complications and 11 (26.2%) major complications. There were 6 (31.6%) major and 4 (21.1%) minor complications in the midline mandibulotomy and both 5 (21.7%) major and minor complications in the paramidline mandibulotomy. Conclusion: There was no significant difference in the mandibulotomy-related complication rate between midline and paramidline mandibulotomies. Paramidline mandibulotomy, which preserves the geniohyoid and genioglossus muscles, should be a better function-preserving operation than midline mandibulotomy.
