Orthognathic Surgery—LeFort I Osteotomy

“…Preoperative planning and a comprehensive patient assessment are arguably the most important aspects of orthognathic surgery. 7 Patient assessment should include a detailed medical history as well as a thorough extraoral facial and intraoral examination in both the frontal and profile view. Radiographic evaluation is important to augment and support clinical findings that include cephalometric evaluation in addition to three-dimensional analysis via either conebeam computed tomography or traditional computed tomographic scans 8 (►Fig.…”

“…Additionally, patients with cleft deformities also present with significant asymmetries, general maxillary deficiency, and occlusal cants that often necessitate bimaxillary surgery as opposed to single jaw skeletal correction. 7,10 Certain features that are unique to cleft patients and may impact planning and surgery include the potential need for alveolar cleft grafting, possibility of congenitally missing dentition, and a significant arch-width discrepancy. 7…”

Management of Tooth Discoloration after Orthognathic Surgery Complications: Report of Two Cases

“…The bilateral sagittal split ramus osteotomy is performed through a bilateral intraoral incision in the mandible, creating a fracture that allows mandibular movement, while the Le Fort I osteotomy aims to expose the maxilla, for a subsequent movement to the planned position (Sousa & Turrini, 2012). A variation of Le Fort I osteotomy is the segmental Le Fort I osteotomy, which is useful for the treatment of transverse and vertical jaw discrepancies, such as anterior open bite (Ho et al, 2011).This technique offers good stability (Bauer & Ochs, 2014). The combined maxillary and mandibular orthognathic surgery with counterclockwise rotation of the maxillo-mandibular complex is indicated in patients with long-face pattern, who usually have an altered respiratory pattern with sleep disorders, such as snoring, daytime fatigue, and apnea (Esteves et al, 2014).…”
