Is robotic surgery an option for treating sleep apnea?
Robotic surgery, specifically transoral robotic surgery (TORS), is a surgical option for obstructive sleep apnea (OSA) when standard treatments like positive airway pressure (PAP) therapy fail or are not tolerated. TORS uses a robotic system to access and remove or modify tissue in the throat, such as the tongue base or epiglottis, that blocks the airway during sleep. It is not a first-line treatment; doctors typically try PAP therapy first. TORS is considered for people with specific anatomical obstructions, like a large tongue base or a curled epiglottis, who have not improved with other treatments.
What the research says
TORS has been shown to be a safe and effective way to address tongue base obstruction in OSA. A 2016 review noted that TORS provides wide-field, high-definition 3D visualization and precise instrumentation, with advantages over open procedures including less operative time, quicker recovery, and no external scars 6. A 2025 prospective study of 110 adults with moderate to severe OSA who underwent TORS tongue base resection found it was feasible without tracheostomy, with a mean hospital stay of 8.5 days, and identified factors that predicted surgical success 7. Another study focused on robotic trimming of a curled epiglottis (omega epiglottis) in 21 patients, showing significant improvement in apnea-hypopnea index (AHI) scores, with 85.71% achieving surgical success and 38% achieving complete relief 8. A systematic review of the DaVinci Single-Port TORS platform also included 37 patients who had tongue-base surgery for sleep apnea, confirming its feasibility across multiple indications 3. However, these studies are mostly small or observational, and TORS is not a cure for everyone. Success depends on the specific site of airway collapse and patient characteristics. Also, a review on bariatric surgery noted that patients with sleep apnea tend to lose slightly less weight after surgery, which is relevant because weight loss is a common treatment for OSA 4.
What to ask your doctor
- What is my specific site of airway obstruction, and is it suitable for robotic surgery?
- What are the success rates and risks of TORS for someone with my anatomy and severity of sleep apnea?
- Are there non-surgical options I should try first, such as PAP therapy or oral appliances?
- How long is the recovery, and what can I expect in terms of pain, swallowing, and voice changes?
- Will I need a follow-up sleep study after surgery to confirm improvement?
