Maxillomandibular advancement (MMA) or orthognathic surgery, also sometimes called bimaxillary advancement (Bi-Max), or maxillomandibular osteotomy (MMO), is a surgical procedure or sleep surgery which moves the upper jaw (maxilla) and the lower jaw (mandible) forward. The procedure was first used to correct deformities of the facial skeleton ...
Currently, surgeons often perform maxillomandibular advancement surgery simultaneously with genioglossus advancement (tongue advancement). The genioglossus advancement pulls the tongue forward to decrease the amount of tongue blockage during sleep. MMA is one of the most effective surgical treatments for sleep apnea, with a high success rate.
Orthognathic surgery (/ ˌ ɔːr θ ə ɡ ˈ n æ θ ɪ k /), also known as corrective jaw surgery or simply jaw surgery, is surgery designed to correct conditions of the jaw and lower face related to structure, growth, airway issues including sleep apnea, TMJ disorders, malocclusion problems primarily arising from skeletal disharmonies, and other orthodontic dental bite problems that cannot ...
The first involves surgery of the soft tissue (tonsillectomy, uvulopalatopharyngoplasty) and the second involves skeletal surgeries (maxillomandibular advancement). First, Phase 1 or soft tissue surgery is performed and after re-testing with a new sleep study, if there is residual sleep apnea, then Phase 2 surgery would consist of jaw surgery.

In the same year, through his research, he presented a surgical protocol utilizing bimaxillary advancement and adjunctive procedures for the treatment of obstructive sleep apnea syndrome (OSAS) in patients affected by facial or mandible retrusion, demonstrating a high success rate in reducing the apnea/hypopnea index and improving patient outcomes.
Genioglossus advancement (GA) is a surgical procedure or sleep surgery in which the base of the tongue is pulled forward. [1] It is usually to increase airway size due to deformity or a sleep breathing disorder. This procedure is frequently performed with either uvulopalatopharyngoplasty or maxillomandibular advancement surgeries. Tongue ...
