Transoral Robotic Tongue Base Resection in Obstructive Sleep Apnoea-Hypopnoea Syndrome: A Preliminary Report

Abstract

PURPOSE OF THE STUDY: To evaluate the feasibility, tolerability and efficacy of tongue base management by means of transoral robotic surgery (TORS) in patients suffering from the obstructive sleep apnoea-hypopnoea syndrome (OSAHS) primarily related to hypertrophy of the tongue base. PROCEDURE: Seventeen patients with OSAHS principally related to tongue base hypertrophy were managed by means of TORS (Intuitive da Vinci(R)). Patients with a minimum follow-up of 3 months were evaluated. RESULTS: Ten patients [mean preoperative apnoea-hypopnoea index (AHI): 38.3 +/- 23.5 SD] were included in the study. By means of robotic technology, the tongue base and the epiglottis could be managed. The postoperative polysomnographic results were fairly good (mean postoperative AHI: 20.6 +/- 17.3 SD), and the functional results (pain, swallowing and quality of life) are very encouraging; altogether, complications were rare and of minor importance. CONCLUSIONS: Transoral robotic tongue base management in patients with OSAHS primarily related to tongue base hypertrophy is feasible and well tolerable. These preliminary results are encouraging and worthy of further evaluation.
