Reconstruction of oral cavity defect using versatile buccinator myomucosal flaps in the treatment of cT2–3, N0 oral cavity squamous cell carcinoma: Feasibility, morbidity, and functional/oncological outcomes

OBJECTIVES: To evaluate the results of oral cavity reconstruction using various types of buccinator myomucosal flap (BMMF) for the treatment of cT2-3 oral cavity squamous cell carcinoma (OCSCC). MATERIALS AND METHODS: Twenty-two consecutive patients who underwent surgical management for OCSCC and reconstruction using various types of BMMF were enrolled. Surgical results, complications, speech/swallowing outcomes, and recurrence were evaluated. RESULTS: The mean flap harvest time was 28.6 min. Complete flap necrosis occurred in one (4.5%) patient in whom an island flap was used. There were no other major complications. All patients demonstrated normal speech and swallowing functions, with articulation correctness >90% and a mean swallowing satisfaction score of 9.6. Occult neck lymph node metastasis was found in three (13.6%) patients; however, no recurrence at level I was observed. CONCLUSIONS: Reconstruction of the oral cavity using various types of BMMF is feasible for treatment of cT2-3 OCSCC, and yields favorable outcomes with minimal morbidity.
