Antegrade Bipedicled Submental Island Flap for Anterior Oropharyngeal Defect Reconstruction after Ablative Surgery

Background: The submental island flap (SIF) can be easily and safely harvested in a single stage operation. Although the flap has a good blood supply, for patients who have undergone preoperative radiation or laryngeal suspension, a more reliable flap with a robust blood supply is necessary.

Objective: The aim of this study is to evaluate the outcomes of a bipedicled SIF for anterior oropharyngeal defect reconstruction after ablative surgery.

Methods: Five patients with anterior oropharyngeal cancer who underwent surgical resection followed by immediate reconstruction with anterograde bipedicled submental island flap from July 2009 to February 2012 were ob-served.

Results: Of the 5 patients, aged from 65 to 77 years, in 2 cases there was recurrence after radiation therapy. The mean operation time was 255 mins and blood loss was 149cc (40-350 cc).The patients could consume food orally 11.4 days (mean time)after surgery. The function of swallowing was excellent in all cases and there were no cases of flap complication. Follow up ranged from 15 to 56 months, during which time none of the patients developed recurrence.

Conclusion: The antegrade bipedicled SIF for anterior oropharyngeal defect is a valid surgical option because of its high success rate, ease of harvesting and good swallowing function after operation.
