About the Procedure
Sliding genioplasty is a procedure that moves the chin segment of the lower jaw forward. Because the main muscle of the tongue attaches to the back of this segment, advancing it pulls the tongue base forward and can enlarge the airway behind the tongue.
In sleep surgery, genioplasty (sometimes performed as a genioglossus advancement) targets tongue-base collapse, one common pattern in obstructive sleep apnea. It is often used as part of a multilevel plan rather than alone, and patient selection depends on where the airway collapses.
At Norelle Health, sliding genioplasty for sleep apnea is considered for carefully selected patients, typically after airway evaluation including sleep endoscopy. We discuss how it fits with other treatments and what to expect from recovery and results.
Who may be a candidate
It is considered for patients whose airway evaluation shows tongue-base collapse and who cannot tolerate CPAP or want a surgical option as part of a multilevel approach.
Sleep endoscopy and imaging help confirm that tongue-base advancement is likely to help. Dental health and jawbone anatomy are assessed to plan the procedure safely.
How it is performed
Under general anesthesia, the surgeon makes an incision inside the mouth to access the chin segment of the lower jaw. A controlled cut frees a portion of bone that carries the tongue-muscle attachment, which is advanced forward and secured with a small plate and screws.
Because the incision is inside the mouth, there are no external scars. It may be combined with palate, nasal, or other airway procedures in the same setting.

Recovery and aftercare
Recovery is usually manageable but involves a healing period.
- Expect chin and lip swelling and soreness for the first week or two
- Follow a soft diet and gentle oral hygiene as directed
- Many patients return to light activity within one to two weeks
- Numbness of the lower lip or chin is common and usually improves over time
- Attend follow-up to confirm healing and assess airway response
Risks and alternatives
Risks include swelling, infection, bleeding, temporary or, less commonly, lasting numbness of the lower lip and chin, changes in chin contour, dental or bone-healing issues, and incomplete improvement.
Alternatives include CPAP, oral appliances, upper-airway stimulation, and other tongue-base or jaw procedures such as maxillomandibular advancement, which addresses the airway more broadly.
Results and follow-up
When tongue-base collapse is a key contributor, genioplasty can help reduce airway obstruction, particularly as part of a multilevel plan. Results depend on anatomy and the overall treatment strategy.
Follow-up confirms bone healing and chin contour and usually includes a sleep study after recovery to measure the effect on the apnea.

The tongue's main muscle attaches to the chin segment of the lower jaw. Advancing that segment pulls the tongue base forward, which can enlarge the airway behind the tongue during sleep.
It is most often part of a multilevel plan combined with palate, nasal, or other airway procedures, because sleep apnea frequently involves more than one site of collapse.
No. The procedure is performed through an incision inside the mouth, so there are no external facial scars.
Advancing the chin segment can subtly alter chin contour. This is planned in advance and discussed with you before surgery.
Most patients have swelling and soreness with a soft diet for the first week or two and return to light activity within one to two weeks, while numbness can take longer to resolve.
Genioplasty advances only the chin segment to target the tongue base, while maxillomandibular advancement moves both jaws to enlarge the airway more broadly. The choice depends on anatomy and severity.
Alternatives include CPAP, oral appliances, upper-airway stimulation, and other airway surgeries. A complete evaluation helps determine the best fit.
