Maxillomandibular advancement for treating obstructive sleep apnea

Maxillomandibular advancement is an invasive but effective surgical option in the treatment of obstructive sleep apnea (OSA) for patients who have severe AHI index or with OSA that has been refractory to other surgical methods. Maxillomandibular advancement achieves enlargement of the nasopharyngeal, retropalatal, and hypopharyngeal airway by physically expanding the facial skeleton through Le Fort I maxillary and mandibular sagittal split osteotomies. Although MMA is known to be reserved for patients with craniofacial dysmorphism, patients with normal osseous structure are often surgical candidates and have similarly good outcomes.
