MMA Surgery: The Jaw Procedure That Also Treats Sleep Apnea
Maxillomandibular advancement — MMA, or "bimax advancement" — occupies a unique position in facial surgery. It is one of the most effective surgical treatments for obstructive sleep apnea (OSA), and it happens to produce, as a structural consequence, a stronger jawline and a more projected profile. It is the clearest example of what this practice stands for: function and facial structure are the same architecture.
How moving the jaws opens the airway
The tongue and soft palate are suspended from the mandible and maxilla. When both jaws are surgically advanced, those soft tissues move forward with them, and the airway behind the tongue and palate — where obstruction happens during sleep — becomes structurally larger. Unlike soft-tissue procedures that trim tissue and often relapse, MMA enlarges the corridor itself. In properly selected patients it delivers some of the highest surgical success rates reported for OSA.
Who is a candidate?
- Adults with moderate-to-severe OSA confirmed by a sleep study (polysomnography)
- Patients who cannot tolerate CPAP, or do not want a lifetime of device dependence
- Especially those with retruded jaws — where the anatomy that causes the apnea is the same anatomy weakening the profile
- Patients who failed oral appliances or previous soft-tissue surgery
The decision is made together with a sleep physician; CT-based airway analysis and cephalometrics form the basis of the plan.
Planning: millimetres decided before the OR
How many millimetres of advancement, how the occlusion is preserved, what happens to the airway volume — in our practice all of it is simulated beforehand in AI-assisted 3D planning software developed by Prof. Basa. You review the skeletal plan and the projected airway change before surgery, not after.
Recovery and what to expect
Hospital stay is typically 1–2 nights. Swelling peaks in the first week and a soft diet is kept for the early weeks; most patients return to social life in 2–3 weeks. Many report a difference in snoring and daytime energy early on — but the objective verdict comes from a follow-up sleep study once healing is complete. The profile change is a by-product, and for most patients with retruded jaws, a welcome one: this is the rare surgery where treating a disease and strengthening the jawline are the same operation.
A note on "getting MMA for the jawline"
Some communities discuss MMA purely as an aesthetic upgrade. Our position is consistent: advancement of both jaws is real surgery with real indications. When a skeletal deformity or documented OSA is present, it is an excellent operation. As a casual cosmetic shortcut on normal anatomy, it is not — and a consultation here will tell you honestly which side of that line you are on.
