We aimed to compare the differences between free flap and pectoralis major myocutaneous flap (PMMF) for reconstruction in oral cavity cancer patients. Patients who received free flap or PMMF reconstruction after ablation surgeries were eligible for the current study. The patients' demographic data, medical history, and quality of life scores were collected and analyzed. A total of 491 patients' records were obtained. Among them, 100 patients completed a quality of life questionnaire. No significant differences could be found in age, morbidity, stage, and hospitalization between the free flap and PMMF groups. However, there were significant differences between both groups in gender, primary site, peri-operative blood loss, and operation duration. Patients reconstructed with free flap had better speech and shoulder functions as well as better mood status. Data from this study provide useful information for physicians and patients during their discussion of treatment modalities for oral cancers.
