The Microvascular Basis of the Superior Thyroid Artery Perforator Flap

Abstract

BACKGROUND: The superior thyroid artery perforator flap has been presented previously in this Journal as a locoregional flap that provides an excellent tissue match with minimal donor morbidity for lateral face and temple defects. In the current study, the authors aimed to describe the microvascular anatomy of this flap. METHODS: The authors used in vivo computer tomographic angiography, cadaveric dissection, and ex vivo angiography in order to improve surgical safety and application of this technique. RESULTS: The authors provide a detailed map of the microvasculature that is critical to success in this technique, in addition to useful surface anatomical landmarks for ready application in t..
