An 18-year-old woman with mild Crouzon syndrome was referred with malocclusion and mandibular protrusion. Examination revealed Class III canine and molar relationships, hypoplastic maxilla, 1-mm overbite, and -2-mm overjet. Analysis showed 69° sella-nasion-A, 73.6° sella-nasion-B, and -4.6° A point-nasion-B point angles. Polysomnography revealed respiratory disturbance and 6.3% oxygen desaturation indices of 5.4/h and 9.0/h. We performed double-jaw surgery using high Le Fort I osteotomy and bilateral sagittal split ramus osteotomy for midfacial deformity correction. Twelve months post-surgery, her measures were 70.8°, 72°, -1.2°, 3.0/h, and 6.1/h, respectively. Esthetics were satisfactory. High Le Fort I osteotomy is effective for midfacial deformity correction in patients with Crouzon syndrome.
