About this trial
The investigators have previously proposed a prediction model for difficult transoral and submental thyroidectomy through a retrospective study. In order to better promote transoral and submental endoscopic approach for thyroid surgery and to set up an appropriate training course, the investigators aim to renovate and validate the prediction model through a prospective study.
