maxillary advancement
Surgical procedure to move the upper jaw forward to correct midface deficiency and improve facial balance.
Full Definition
Maxillary advancement is an orthognathic surgical procedure typically performed through a Le Fort I osteotomy to move the maxilla anteriorly, correcting midface retrusion and Class III malocclusion. The procedure may be combined with bone grafting to fill gaps created by advancement and is often performed in conjunction with mandibular surgery for optimal facial balance. Advancement distances typically range from 4-10mm, with larger movements requiring careful consideration of soft tissue tension and airway effects.
Usage
Usage note: Specify measurement when documenting surgical movements for accuracy.
