Abstract
Transoral endoscopic thyroid surgery has been introduced in a few institutions. The purpose of this study was to present an innovative hybrid space-maintaining method for the tri-vestibular approach. Eighteen consecutive patients underwent transoral endoscopic thyroidectomy. Three incisions were made in the vestibule. The surgical space was maintained with CO2 insufflation along with a suspension device. Thyroidectomy and central neck dissection (CND) were performed safely and effectively. The mean operation time was 124 minutes for a simple lobectomy, subtotal thyroidectomy, and isthmectomy in 8 patients, 172 minutes for hemithyroidectomy with ipsilateral CND in 8 patients, and 205 minutes for total thyroidectomy with ipsilateral CND in 7 patients. Transient superior laryngeal nerve (SLN) injury occurred in 3 patients and transient mental nerve injury was found in 1 patient. No evidence of recurrence or metastasis was found at follow-up. This approach brings satisfactory cosmetic effect along with minimal invasion. Further study is needed to verify its validity.
