Oropharyngeal reconstruction after ablative surgery is a challenge. The results of a retrospective study of 17 patients who underwent total or sub-total soft palate reconstruction with a buccinator myomucosal island flap, between 2008 and 2016, are reported herein. An analysis of flap type and size, harvesting time, and postoperative complications was performed. Patients underwent standardized tests to assess the recovery of sensitivity, deglutition, quality of life (QoL), and donor site morbidity, at >6 months after surgery or the end of adjuvant therapy, if performed. All flaps were transposed successfully. Only minor donor and recipient site complications occurred. The sensitivity assessment showed that touch, two-point discrimination, and pain sensations were recovered in all patients. Significant differences between the flap and native mucosa were reported for tactile (P=0.004), pain (P=0.001), and two-point discrimination (P=0.001) thresholds. The average deglutition score reported was 6.1/7, with only minimal complaints regarding deglutition. The QoL assessment showed high physical (24.6/28), social (25/28), emotional (19.1/24), and functional (24.6/28) scores. No major donor site complications were noted in any patient; the average donor site morbidity score was 8.1/9. Buccinator myomucosal island flaps represent a valuable functional oropharyngeal option for reconstruction, requiring a short operating time and presenting a low donor site morbidity rate.
