title: Choice of recipient vessels for nasal ala reconstruction using a free auricular flap.
abstract: Starting in 2010, we experienced seven cases of full-thickness nasal ala defects reconstructed with free auricular flaps. We modified previous methods using retrograde free auricular flaps by including both retrograde and antegrade superficial temporal vessels to enhance the venous drainage of the flap. Based on our experience and the findings of previous reports, we developed an algorithm to insert free auricular flaps for use in nasal ala reconstruction, and to select the recipient vessels. Eight free auricular flaps were transferred in seven cases. In all cases, one artery anastomosis and two venous anastomoses were performed. The facial artery was used as the recipient artery at the nasolabial fold in five cases, and the proximal stump of the superficial temporal artery was used as the recipient vessel via a vein graft in two cases. The facial vein at the nasolabial fold was used in six cases, and the facial vein at the mandible via a vein graft was used in one case. In all cases, the angular vein at the medial canthus was available and used as the second recipient vein. The key to success with free auricular flap transfer for nasal ala reconstruction is to select the proper recipient vessel. We believe that our algorithm and procedure will increase the rate of successful operations.
