Abstract
AbstractNasal alar reconstruction with the free auricular helix flap is challenging because the flap is prone to congestion. We report two cases of successful nasal alar reconstruction using free auricular helix flaps utilizing the flow‐through concept. Case 1 was a 37‐year‐old man presented with a basal cell carcinoma in the nasal cavity. After radical excision, we transferred a 20 × 20 mm2 free flow‐through auricular helix flap by interposing the T‐portion of the superficial temporal artery of the flap to the transected facial artery. Case 2 was a 39‐year‐old man presented with neurofibromatosis type I and a nasal alar deformity after multiple excision of the neurofibroma. We corrected the deformity with a 26 × 22 mm2 free auricular helix flap. We used a flow‐through arterial graft of the descending branch of the lateral circumflex femoral artery to bridge the gap between the flap artery and the recipient facial artery of the submandibular region because an appropriate recipient artery was not available around the defect. Both of the flaps survived without vascular compromise and no donor‐site complication occurred. The esthetic results of the nasal ala were satisfactory. The flow‐through arterial anastomosis diverted the arterial flow to the peripheral side of the recipient artery and relieved flap congestion. These physiological properties of flow‐through anastomosis may stabilize the flap circulation and improve the success rate of free auricular helix flap transfer.
