Maxillomandibular Advancement in the Management of Obstructive Sleep Apnea

الملخص EN

Maxillomandibular advancement (MMA) is a surgical option for obstructive sleep apnea (OSA).

MMA involves forward-fixing the maxilla and mandible approximately 10 mm via Le Fort I maxillary and sagittal split mandibular osteotomies.

We retrospectively reviewed outcomes from 24 consecutive OSA patients who underwent MMA at our institution.

MMA resulted in an 83% reduction in the group mean apnea-hypopnea index (AHI) per polysomnography an average of 6.7 months after surgery.

Forty-two percent of patients achieved a post-MMA AHI of less than 5 events/hour sleep and 71% achieved an AHI less than or equal to 10 events/hour sleep.

The Epworth Sleepiness Scale score decreased by an average of 5 post-surgery.

No parameters predictive of cure for OSA by MMA were identified.
