Transoral endoscopic thyroidectomy vestibular approach: Results after 53 first cases

Introduction: Transoral endoscopic thyroidectomy through vestibular approach allows access to the thyroid with the best cosmetic results as there are no visible scars. Methods: Here we present a prospective observational study of 53 patients which underwent transoral endoscopic thyroidectomy from July 2017 to June 2021. Results: Fifty-two cases (98.1%) were women (median age 44 years old). Thyroid nodule was the main surgical indication accounting 73.6% of cases. We performed 42 lobectomies and 11 total thyroidectomies; 4 left central neck dissection were also associated. The median surgical time for port placement was 14 min, and for lobectomy, total thyroidectomy and left central neck dissection were 80, 140 and 30 min, respectively. The median of hospital stay was 2 days. Dysphonia was present in 4 patients (7.5%); however, laryngoscopy only confirmed laryngeal nerve impairment in 2 cases, one of them classified as permanent (1.6%). In those patients that underwent total thyroidectomy, the rate of transient hypoparathyroidism was 18.2% whereas permanent was 0%. Regarding complications associated to the new approach, transient chin numbness appeared in all patients with a variable degree of intensity. Conclusions: Transoral surgery is a recent approach in our unit. Our results, based on the first 53 patients, show that it is a safe and effective approach when performed in appropriately selected patients offering the best cosmetic result. Besides, new complications associated to the approach has been shown to be transient.
