From November 2013 to November 2018, 112 patients with oral cavity squamous cell carcinoma (SCC), 79 men and 33 women, underwent infrahyoid flap reconstruction after tumor ablation procedures. The age of patients ranged from 29 to 76 years, with median of 58 years. The primary sites of patients in the series were oral tongue (68), floor of mouth (31), and alveolar ridge (13) (table 1).
The functional capacity of reconstructed patients was subsequently evaluated by three doctors (head and neck surgeon, radiation oncologist, physiatrist) with the scores averaged (table 23,34). This assessment was conducted at 3 months after reconstructive operation (28 patients not require adjuvant radiotherapy) or after radiotherapy (84 patients).
