ObjectiveTo assess the clinical application of supraclavicular flap in postoperative defect repair of hypopharyngeal carcinoma.MethodsClinical data of 5 patients receiving postoperative defect repair of hypopharyngeal carcinoma with pedicled supraclavicular flap at Sun YatSen University Cancer Center between July 2017 and Jan 2019 were analyzed retrospectively. The sizes of the flaps were measured in (6~20) cm×(4~6.5) cm．The harvesting time of the flap, the amount of intraoperative blood loss, the time of postoperative tube drainage, the outcome of the flap and the healing of the donor site were recorded.ResultsHarvesting time for the supraclavicular flap ranged from 25 to 35 minutes with an average of 30 minutes．The amount of intraoperative blood loss ranged from 50 to 80 ml, averaging 56 ml．The time of postoperative tube drainage ranged from 5 to 10 days, averaging 6.6 days．All flaps survived and all donor area defects were directly sewed and stitched without complications.ConclusionWith advantages of simple preparation technique, reliable repair of defects, no need for microvascular anastomosis, and aesthetic satisfication of wound as well as mild local function impairment, the supraclavicular flap can be used for postoperative defect repair of hypopharyngeal carcinoma.
