Abstract

Abstract: Background: Mandibulotomy helps access posterior oral cavity tumors. If osteotomy designs affect postoperative and postradiotherapy complications, needs to be tested clinically. Methods: Two hundred and eighteen patients who underwent midline mandibulotomy for primary tongue cancer wide excision and flap reconstruction at Chang Gung Memorial Hospital during 2014‐2019. Results: There were 114 straight, 54 notched, and 50 stair‐stepped osteotomy cases. Stair‐stepped osteotomy had less advanced tumor stages ( P = .009) and notched osteotomy more common single‐plate fixations ( P = .012). The former showed higher mandibular heights ( P = .000) and more intact midline teeth ( P = .011) than notched and straight ones. Straight osteotomy cases showed lower early infection rates ( P = .039). Single‐plate fixation was related to more flap dehiscence ( P = .001) and oro‐cutaneous fistulas ( P = .035). Conclusions: Complex osteotomy does not offer long‐term benefits in midline mandibulotomies for primary tongue cancers and has higher early infections. Single‐plate fixation increases postoperative complications.
