Robotic transoral vestibular parathyroidectomy: Two case reports and review of literature.

Advances in preoperative localization studies and demands for scarless surgery have promoted the investigation for remote techniques in parathyroid surgery. Transoral vestibular approach seems to provide the most comfortable and safest access to the neck. In this paper, we report our initial experience with robotic transoral vestibular parathyroidectomy (RTVP) in four patients with primary hyperparathyroidism. The surgery was performed with the Da Vinci system through three trocars introduced from the lower lip vestibule. The procedure was converted to open in two patients due to inappropriate preoperative localization. The mean operative time was 169 min. No postoperative complications were seen. Patients were discharged on postoperative day 1. RTVP is a feasible and safe technique, which allows better surgical exposure and manipulation of the instruments. The advantages of transoral vestibular approach can be enhanced by robotics. Further studies are needed to analyze complications and costs.
