Abstract

The infrahyoid flap is a myocutaneous pedicled flap mainly nourished by the superior thyroid vessels through the perforators of theinfrahyoidmuscles. This thin and pliableflap provides a skin island of about 7 by 4cm from the central part of the anterior neck. Theflapcan be transferred on its pedicle of superior thyroid artery and vein to reconstruct medium sized head and neck defects created aftercancer ablation. We have successfully used this flap in a series of 40 cases with no total flap loss and with 1 case of superficial skin necrosis. The aim of this review is to highlight the clinical usefulness of this pedicled flap even in the microvascular free flap era. A comprehensive review of the available literature reporting on the infrahyoid flap has been carried out using a web search. The history of the infrahyoid flap, the surgical technique with technical innovations, the clinical utility and limitations of this flap, are reported and discussed. Among the 7 larger series (cohort larger than 50 cases) a total of 956 flaps were performed, and the global success rate was 91.7\%, with failures being mainly related to partial skin necrosis, as the rate of total (skin and muscle) flap necrosis was only 1\%. This flap is reliable, easy to harvest during neck dissection, oncologically safe, it does carry a negligible donor site morbidity. This paper highlights how the infrahyoid flap can represent an excellent reconstructive solution in selected patients and head and neck sites.
