Bimaxillary or maxillomandibular orthognathic surgery

In most candidates to orthognathic surgery , it is necessary to reposition both jaws to achieve proper occlusion and facial harmony, this procedure is known as maxillomandibular surgery, double jaw surgery or bimaxillary orthognathic surgery.

Bimaxillary orthognathic surgery is used to treat malformations such as Class 2 bite, Class 3 bite, facial asymmetry, or open bite or crossbite, among other malocclusions when a monomaxillary surgery is not enough to repair the patient's problems. This procedure is carried out by means of a Le Fort I osteotomy, which allows to move the maxilla (or upper jaw) in three dimensions (lengthen/shorten, move forward/backward and rotate), combined with a Bilateral Sagittal Split Osteotomy (BSSO), which allows to move the lower jaw forward or backward. In this way, the maxillofacial surgeon can harmonize the entire lower third of the patient's face, achieving an adequate function, in addition to a correct proportion of the facial features.

Thanks to our 3D planning system and our minimally invasive approach, maxillomandibular surgery at the Maxillofacial Institute takes between 90 and 120 minutes, and patients can go home the day after the intervention. Learn more by calling +34 933933185 or write to
