Description
Summary:The purpose of this study was to evaluate the oncologic safety of submental island flap (SIF) reconstruction in clinically node-negative oral cancer patients. Forty-four clinically node-negative oral cancer patients with tumour size T1–T3 were divided into two groups. The Submental group consisted of 21 patients, who underwent submental island flap reconstruction whereas the control group consisted of 23 patients who underwent reconstruction with other locoregional or free flaps. The locoregional recurrence rate (LRR) and recurrence-free survival (RFS) in these two groups were assessed and compared. The follow-up period in the two groups ranged from six to 28 months, with a median follow-up period of 15 months and 21 months, respectively. Results showed that the LRR in the control and the submental group was 21.7% and 19%, respectively (p = 0.825). Kaplan–Meier curve showed that the difference in recurrence-free survival in the two groups was not statistically significant (p = 0.749). Multivariate and bivariate analyses did not establish any relationship between the predictive parameters and locoregional recurrence. Thus, the Submental island flap is a reliable and versatile locoregional flap for the reconstruction of post-resection defects in oral cancer. It has no predictive influence on locoregional recurrence in clinically node-negative oral cancer patients.
