Single-port endoscopic thyroidectomy via a submental approach: report of an initial experience.

BACKGROUND Based on our experience of trans-areola single-site endoscopic thyroidectomy and a preclinical study in the porcine model, we attempted to develop a new approach called trans-submental single-port endoscopic thyroidectomy (TSSPET). METHODS Two female patients (43 and 27 years old, respectively) were selected for TSSPET. Both were preoperatively diagnosed with benign thyroid nodule by ultrasonography and fine-needle aspiration cytology (FNAC). Two mini-incisions were made in the submental area. The isthmectomy was performed for 1 patient and a right lobectomy for the other. RESULTS This procedure was successfully accomplished in 2 cases. The operative time was 108 minutes and 150 minutes, respectively. No complications occurred. Postoperative hospital stay was 2 days. After 3 months, cosmetic result was satisfactory. CONCLUSION Our initial experience demonstrates that the TSSPET is feasible and safe for selected patients. Nevertheless, large series and comparative studies could be necessary to further confirm its effectiveness.
