Hypothyroidism After Using Superior Thyroid Artery as A Recipient Artery.

Abstract

Superior thyroid artery (SThA) is a common recipient artery in free tissue transfer even after total pharyngolaryngoesophagectomy (TPLE) with hemithyroidectomy. The aim of this study was to evaluate whether the use of SThA as a recipient vessel affect thyroid function in patients undergoing TPLE with hemithyroidectomy. From 2011 to 2020, 91 patients who underwent free jejunum transfer after TPLE with hemithyroidectomy were divided into two groups. In Group1 (n=47), the contralateral SThA was used for the anastomosis. In Group2 (n=44), other vessels were used. Retrospective chart review was performed comparing postoperative thyroid function between two groups. In group1, 17 patients presented hypothyroidism, 21 presented latent hypothyroidism and 9 presented no thyroid dysfunction comparing 15, 19, and 10 respectively in group 2. There were no significant differences between the two groups. Even after hemithyroidectomy, with inferior thyroid arteries are preserved, the SThA can be used as a recipient vessel. 3 Laryngoscope, 133:557-561, 2023.
