The infrahyoid myocutaneous flap for reconstruction after oral cancer resection: A retrospective single-surgeon study

Abstract

Objective: To review our experience with infrahyoid myocutaneous flap in reconstruction after oral cancer resection. Methods: Chart reviews were completed for all patients who underwent oral reconstruction with an infrahyoid myocutaneous flap by a single surgeon in the Department of Otolaryngology at Chonburi Cancer Hospital from 2011 to 2017. Characteristics of the patients and postoperative complications were analyzed. Results: Of the 34 patients in the study, 10 (29.4%) developed partial flap loss and 1 (2.9%) developed total flap loss. All cases of partial flap loss resolved with conservative treatment. Apparent cancer involvement of a cervical lymph node was significantly associated with flap failure (odds ratio: 5.0, 95% CI: 1.03–24.28). Conclusions: The infrahyoid myocutaneous flap is a fairly reliable reconstruction method. The flap should be performed with caution in cases with gross lymph node involvement.
