Background Circumferential hypopharyngeal defect with simultaneous skin defect can pose complicated reconstructive challenge for reconstructive microsurgeons. Our experience with the versatile inverted‐omega flap tubing design is proposed to accommodate such problem. Methods From 2012 to 2015, 13 anterolateral thigh (ALT) flaps and one anteromedial thigh (AMT) flap were harvested for reconstruction of circumferential hypopharyngeal defects with skin defects in 14 patients. All patients were males except one. Patient age ranged from 42 to 67 years (average, 53.1 years). Fifty‐seven percent were recurrent cases. All but one patient received preoperative chemoradiotherapy. Results The average flap size was 29 × 8 cm (range: 25–31 × 6–10 cm 2 ). An average of 2.6 perforators was included in each flap (2–4 perforators/flap). All flaps survived. One venous thrombosis was noted and salvaged after thrombolectomy and vein graft. The mean follow‐up period was 25 months. The fistula rate was 21.4% (three patients). One fistula never healed because of early recurrence; one fistula healed after surgical intervention; and one fistula need a loco‐regional flap for secondary reconstruction. Three postoperative strictures were noted (21.4%). Conclusion For the circumferential hypopharyngeal defect with simultaneous neck skin defect, this inverted‐omega ALT tubing design offers an alternative choice for such complicated reconstruction. © 2016 Wiley Periodicals, Inc.
