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.
