Anatomical‐based classification for transoral base of tongue resection

BACKGROUND To propose a classification of transoral base of tongue (BOT) procedures able to provide uniform terminology in order to better define postoperative results. METHODS The classification resulted from the consensus of the different authors and is based on anatomical and surgical principles. RESULTS 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). CONCLUSION The proposed classification could allow us to easily compare data from different centers.
