Renovated Prediction Model for Difficult Transoral and Submental Endoscopic Thyroidectomy

Renovated Prediction Model for Difficult. Transoral and Submental Endoscopic Thyroidectomy

Important: This information is not medical advice. Talk to your doctor about whether a clinical trial is right for you.

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.
