Maxillomandibular Progress ( MMA ) or orthognathic surgery, also sometimes called bimaxillary progress ( Bi-Max ), or maxillomandibular osteotomy ( MMO ), is a surgical or sleeping procedure that moves the maxilla (maxilla) and mandible (lower jaw) forward. This procedure was first used to correct facial skeletal deformity to include malocclusions. In the late 1970s, mandibular progress was noted to improve sleepiness in three patients. Furthermore, maxillomandibular progress is used for patients with obstructive sleep apnea ( see Sleep apnea ).
Currently, maxillomandibular advance surgery is often performed simultaneously with the progress of genioglossus (tongue progression). The progress of genioglossus pulls the tongue forward in a way that reduces the amount of tongue blockage during sleep. MMA has proven to be one of the most effective surgical treatments for sleep apnea, due to its high success rate. However, this procedure is often used after other forms of treatment fail (nasal surgery, tonsillectomy, uvulopalatopharyngoplasty, tongue reduction surgery). There is a longer recovery when compared with other sleep apnea surgery, because the facial bones must be recovered to their new position.
