What effect does transoral robotic surgery (TORS) base of tongue (BOT) reduction have on sleep-related outcomes in patients with obstructive sleep apnea (OSA)?
Bottom line: TORS BOT reduction decreases AHI and symptoms of sleepiness in adult patients with OSA. It is considered successful in a majority of cases, but further studies must be performed to optimize patient selection criteria to achieve higher rates of success.

Background: The first-line treatment for moderate-to-severe OSA is continuous positive airway pressure (CPAP). Despite the important CPAP benefits, adherence rates range from 50% to 70%. Surgery of the tongue base remains challenging due to difficult surgical access and visualization along with uncertainty with regard to the volume of tissue that can be safely excised.
Study design: Retrospective literature review of six articles with 353 patients treated with TORS BOT reduction.
