Anatomical-based classification for transoral base of tongue resection.

Abstract

To propose a classification of transoral base of tongue (BOT) procedures able to provide uniform terminology in order to better define postoperative results. The classification resulted from the consensus of the different authors and is based on anatomical and surgical principles. The classification comprises three types of BOT resections: type 1 is the resection of the entire lingual tonsil to the muscular plane; type 2 is performed by removing the entire lingual tonsil and part of BOT muscles; type 3 is performed by removing the entire lingual tonsil and the entire BOT muscles. Based on the extension of the dissection, we can use the suffix A (contralateral BOT), B (supraglottic larynx), C (lateral oropharynx), and/or D (oral tongue). The proposed classification could allow us to easily compare data from different centers.
