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

In the surgical management of oral cavity squamous cell carcinoma (OCSCC), radical resection with adequate margins is paramount in achieving local control. To obtain microscopically clear margins >0.5 cm, additional resection of normal tissue >1.0–1.5 cm from the gross tumor border is recommended [1,2]. Therefore, defect size is always significantly larger than the tumor itself, and reconstruction is commonly required to establish form and function in the resected organ, with the exception of some T1 and T2 OCSCCs.
