Extending the Inferior Limits of Supracricoid Partial Laryngectomy: A Clinicopathological Correlation

Abstract

Preoperative assessment of arytenoid mobility and extent of subglottic extension are reliable predictors of cricoid invasion by glottic squamous cell carcinoma. Organ preservation surgery is oncologically safe in the setting of glottic squamous cell carcinoma with subglottic extension of 15 mm or less and without arytenoid fixation.
