First case report of benign subcutaneous thyroid tissue implantation following transoral endoscopic thyroidectomy vestibular approach (TOETVA)

Following the era of remote access thyroid surgery in the 1990s, several techniques were developed including transoral endoscopic thyroidectomy vestibular approach (TOETVA), which was invented in 2016. TOETVA has gained acceptance and proven comparable results to the conventional open thyroidectomy. Despite the potential complications that may occur as a result of remote access thyroid surgery, such as nerve, vascular, and tracheal injury, seroma, and hypoparathyroidism, there was an extremely rare late complication of a benign subcutaneous thyroid implantation, which have not been reported following TOETVA.
