Mandibulectomy, or "mandibular swing" osteotomy, is routinely used, to access the deep tumors in the posterior oropharynx and oral cavity. However, a study suggests that complex osteotomy does not offer long-term benefits in midline mandibulotomies for primary tongue cancers and has higher early infections.

Two hundred and eighteen patients who underwent midline mandibulotomy for primary tongue cancer-wide excision and flap reconstruction were included in the study.

There were 114 straight, 54 notched, and 50 stair?stepped osteotomy cases.

--Stair?stepped osteotomy had less advanced tumor stages and notched osteotomy more common single?plate fixations.

--The former showed higher mandibular heights and more intact midline teeth than notched and straight ones.

--Straight osteotomy cases showed lower early infection rates. Single?plate fixation was related to more flap dehiscence and oro?cutaneous fistulas.

Overall, 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.
