Thyroid gland management in total laryngectomy: Meta-analysis and surgical recommendations

Thyroid gland invasion is not a general feature of squamous cell laryngeal carcinoma. When present, it is strongly associated with anteroinferior spread of advanced laryngeal tumors. Thyroidectomy may only be required during total laryngectomy for transglottic tumors, subglottic tumors, and tumors with subglottic extension >10 mm.
