Transoral Robotic Surgery (TORS) uses the da Vinci surgical robot to perform precise tissue removal at the base of the tongue and in the throat. The robotic arms provide enhanced visualization and dexterity, allowing surgeons to access difficult-to-reach areas through the mouth without external incisions. For sleep apnea, TORS is primarily used to reduce enlarged lingual tonsils or excess tissue at the tongue base that causes obstruction. The procedure offers advantages over traditional open surgery including less pain, faster recovery, and reduced risk of complications.
The cost of TORS surgery ranges from $15,000 to $40,000, with an average cost of approximately $25,000. These costs can vary significantly based on:
Best for: Tongue base obstruction, lingual tonsil hypertrophy
TORS is typically covered by insurance when deemed medically necessary for obstructive sleep apnea treatment. Most major insurance companies, including Medicare, cover this procedure when patients meet specific criteria.
CPT Code(s): 41530

Without insurance, TORS typically costs between $15,000 and $40,000, depending on the provider, location, and complexity of the case. Many providers offer payment plans or financing options.
Yes, TORS is typically covered by insurance when deemed medically necessary for obstructive sleep apnea. Most patients need to have tried CPAP therapy first. Check with your insurance provider for specific coverage details.
TORS has a success rate of 60-68% in reducing sleep apnea severity. The procedure can reduce AHI (apnea-hypopnea index) by 50-60% on average.
Full recovery from TORS typically takes 2-3 weeks. Most patients can return to work in 2 weeks. Hospital stay is usually 1-2 days.
