P Orthognathic surgery
Orthopedic orthognathic procedures often require a sagittal splitting of the mandible to move the lower jaw either forward or back. A Le Fort I or Le Fort II osteotomy may be performed to move the maxilla in any direction to correct anomalies. Many of these patients have anomalies of the mandible and maxilla, small mouth openings, and appliances that make intubation difficult and airway management challenging.
