Adoption Of The Transoral Endoscopic Vestibular Approach By Head And Neck Surgeons Without Prior Laparoscopic/Robotic Experience

Background Transoral endoscopic vestibular approach (TOEVA) for thyroidectomy (TOETVA) and parathyroidectomy (TOEPVA) is gaining popularity, yet knowledge is based on a limited number of studies, mostly performed by surgeons experienced in laparoscopic\robotic surgery. Methods All patients who underwent TOEVA at our institution between February 2018 and October 2019 were followed prospectively. Main outcomes were ability to accomplish surgery endoscopically (failure defined as conversion to open approach) and complications. Results Seventy-one patients (52 TOETVA and 19 TOEPVA) were included. 98% (51/52) and 100% (19/19) of TOETVA and TOEPVA surgeries were accomplished endoscopically, respectively. Transient vocal cord and mental nerve injuries rates were 8.4% (6/71) and 2.8% (2/71), respectively. Thyroid carcinoma was diagnosed in 27 patients (51.9%), all completely excised with clean margins. Conclusions Adoption of the TOEVA suggested framework by head and neck surgeons without prior experience in laparoscopic/robotic techniques is feasible resulting in nearly 100% of surgeries accomplished endoscopically.
