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.
