Nomogram for Predicting Difficult Transoral and Submental Thyroidectomy

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

About This Trial

No prior studies have stratified the difficulty of transoral and submental thyroidectomy (TOaST). The investigators aimed to investigate preoperative factors as indicators of difficult TOaSTs and to develop a predictive model accordingly.

Who May Be Eligible (Plain English)

Who May Qualify: - Clinical diagnosis of differentiated thyroid cancer with a maximum diameter not exceeding 4 cm - Absence of suspicious lateral lymph nodes or distant metastases - Participants with high cosmetic expectations - Participants who underwent total thyroidectomy and central lymph node dissection. Who Should NOT Join This Trial: - Participants with fusion or fixation of lymph nodes in the neck - Participants with history of neck surgery or radiation - Participants with vocal fold fixation by preoperative fibrolaryngoscope - Participants with preoperative examination suggestive of extrathyroidal invasion - Participants with a significantly restricted neck Always talk to your doctor about whether this trial is right for you.
