Obstructive sleep apnea (OSA) occurs when the airway collapses during sleep, causing repeated breathing interruptions that fragment sleep and deprive the body of oxygen. While CPAP therapy remains the first-line treatment, many patients cannot tolerate it. For moderate-to-severe OSA with identifiable skeletal contribution, surgical jaw advancement can permanently enlarge the airway — often eliminating the need for CPAP entirely.
Maxillomandibular Advancement (MMA)
MMA is the most effective surgical treatment for obstructive sleep apnea, with published success rates exceeding 85%. The procedure advances both the upper jaw (Le Fort I osteotomy) and lower jaw (bilateral sagittal split osteotomy) forward by 8–12mm, physically enlarging the airway behind the tongue and soft palate. Dr. Kahwach performs MMA using the same virtual surgical planning technology used in orthognathic surgery, ensuring precise advancement with aesthetic facial improvement rather than compromise.
Other Surgical Options
Genioglossus advancement — pulling the tongue base attachment forward to open the lower airway. Hyoid suspension — repositioning the hyoid bone to prevent airway collapse. Tongue base reduction — for patients with macroglossia contributing to obstruction.
Who Is a Candidate?
Patients with moderate-to-severe OSA (AHI above 15) who have failed CPAP therapy, cannot tolerate oral appliances, or have clear skeletal jaw deficiency contributing to airway obstruction. A sleep study (polysomnography) is required before surgical planning. Dr. Kahwach coordinates with your sleep medicine physician throughout treatment.
