Nomogram for Predicting Difficult Transoral and Submental Thyroidectomy
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.
Inclusion: 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.
Exclusion: Participants with history of neck surgery or radiation; Participants with fusion or fixation of lymph nodes in the neck; Participants with vocal fold fixation by preoperative fibrolaryngoscope; Participants with preoperative examination suggestive of extrathyroidal invasion; Participants with a significantly restricted neck.
