Versatility of Supraclavicular Artery Island Flap in Head and Neck Reconstruction of Vessel-Depleted and Difficult Necks

Abstract

The advent of microvascular free tissue transfer has given reconstructive surgeons a vast repertoire of treatment options for reconstruction of head and neck defects. However, the success of free flaps in head and neck reconstruction depends on the presence and quality of the recipient vessels in the neck for microvascular anastomosis. The supraclavicular artery island flap can be used to reconstruct a variety of head and neck defects, allowing the reconstructive surgeons to circumvent some of the problems inherent in vessel-depleted necks. The present study reports the use of the supraclavicular artery flap (SCAF) in the reconstruction of vessel-depleted neck and in difficult necks. The present study was a retrospective study of patients who had undergone reconstruction with an SCAF and who also had a difficult neck or vessel-depleted neck in the head and neck surgery section from 2011 to 2012. Our inclusion criteria were patients treated at our institution with an SCAF who also had undergone multiple previous neck surgeries or patients with severely restricted donor options for soft tissue reconstruction. We excluded any patient for whom we did not have adequate follow-up or if the flap procedure was not performed by the faculty of the head and neck section. We identified 8 patients with a total of 9 SCAFs. One patient received bilateral SCAFs. Of the 8 patients, 6 were men and 2 were women. With the exception of 1 patient, all had received previous radiotherapy to the head and neck region. All the patients had undergone multiple surgical procedures. The flap survival was 100%. However, 2 patients had partial loss of the flap, and 2 had partial donor site wound dehiscence. Our overall complication rate was 38%, including dehiscence of the flap and partial loss of the flap. The SCAF is a sound option for reconstructing defects in the head and neck region in patients with previous radiotherapy and in multiple neck surgeries. The surgeon and patient should be aware of the high incidence of complications associated with this reconstructive option.
