Abstract

The transoral endoscopic thyroidectomy vestibular approach (TOETVA) can lead to abnormal sensorimotor changes in the lower lip and chin because of its incision design. This study aimed to explore the surgical outcomes of these changes after TOETVA. A total of 122 patients who underwent TOETVA were reviewed. The original incision design was used for the 39 patients in group A and a modified incision design was used for the 83 patients in group B. The sensorimotor changes in the lower lip and chin were compared. Varying degrees of paresthesia of the lower lip and chin (PoLC) were noted in all group A patients. Approximately 20.5% of group B patients did not suffer from PoLC, and the degree of PoLC in group B was significantly lower (P < 0.001). Abnormal motor function of the lower lip was noted for 23.1% of the patients in group A and 2.4% of those in group B. The incision design plays an important role in the morbidity of sensorimotor changes in the lower lip and chin. Our modified incision design seems minimally invasive and feasible for patients who undergo TOETVA.
