Supraclavicular Artery Island Flap for Head and Neck Oncologic Reconstruction: 15-year Experience, Past, Present, Future

Background:. Head and neck reconstruction poses unique challenges due to the complex structure of the region. Primary goals include soft-tissue coverage, adequate color and texture match, and minimal donor-site morbidity. Local and musculocutaneous regional flaps have largely been replaced with fasciocutaneous free flaps (FFF) over recent years. The supraclavicular artery island flap (SCAIF), a locoregional, fasciocutaneous, axially-based flap, has been shown to produce similar outcomes to FFF. We present our 15-year experience using the SCAIF for head and neck reconstruction, discuss its evolution, and provide case examples for its range of indications. Methods:. Retrospective chart review identified 128 patients who underwent reconstruction of the head and neck with the SCAIF between the years 2006-2021 at Tulane University Medical Center. Patient demographics, lengths of stay, operative times, surgical indications, and complications were recorded. Results:. The cohort mean age was 66.9 years. Mean lengths of stay and follow-up times were 6.9 days and 9.1 months, respectively. The most common indications for SCAIF reconstruction were recurrent radiated neck disease (n=27, 21.1%), pharyngeal wall defects (n=23, 18.0%), and parotidectomy defects (n=21, 16.4%). Overall complication rate was 17.2%. Partial thickness flap loss (5.5%), contained pharyngeal leak (3.2%), and distal tip necrosis (2.4%) were the most common complications. No functional donor site morbidity was encountered. Conclusions:. The SCAIF is a versatile, fasciocutaneous, axially-based flap able to produce similar outcomes to FFF in the reconstruction of the head and neck region while reducing costs, lengths of stay, operative times, and donor site morbidity
