- Abstract
- Background
The study aimed to evaluate the sensory changes on the chin and neck in transoral thyroidectomy.
Methods
We prospectively assessed the cutaneous sensation of 10 zones of the chin, face, and neck in 43 patients who underwent transoral robotic or endoscopic thyroidectomy using the Semmes-Weinstein monofilaments test, preoperatively and postoperatively at 1 week, 1 month, and 3 months.
Results
The sensation of the chin and lower lip did not differ before and after surgery. However, the pressure threshold of the submental and level VI area increased significantly after surgery, and returned to the preoperative level 1 month and 3 months postoperatively, respectively.
Conclusion
In terms of mental nerve injury, transoral thyroidectomy is safe when performed successfully. However, proper placement of oral vestibular incisions and minimal dissection of the chin is essential to avoid mental nerve injury.
