Abstract
In syndromic craniosynostosis, such as Crouzon syndrome, midfacial hypoplasia can

cause exophthalmos and concave facial profile. Though midfacial hypoplasia in

Crouzon syndrome patients can be treated with midface advancement, known as a Le

Fort II or Le Fort III osteotomy, such method can change nasal appearance and

frequently fails to achieve class I occlusion after surgery. This report presents

a case of an aesthetically and functionally successful midfacial augmentation

using rib and cartilage graft along with orthognathic surgery (Le fort I and

bilateral sagittal split ramus osteotomy) for patients with Crouzon syndrome. The

patient was a 21-year-old male with Crouzon syndrome, who had undergone

augmentation rhinoplasty 2 years ago. His main issues were midfacial retrusion

and mild anterior open bite and cross bite and, furthermore, did not want any

change in his nasal appearance. To augment midfacial volume, rib bone graft was

inserted on the inferior orbital rim and costal cartilage graft was done on the

zygomatic area. The costal osteocartilage was fixed with titanium screws.

Additionally, Le Fort I osteotomy and bilateral sagittal split ramus osteotomy

were done to treat the anterior open bite and cross bite. The maxillary segment

was advanced 2 mm and posteriorly impacted 2.5 mm. Then, 5 mm of mandibular

setback was done and the maxillomandibular segment was rotated clockwise.

Finally, genioplasty with 5-mm advancement was done to compensate for the chin

retrusion after performing the mandibular setback. The operation took 425 minutes

and estimated blood loss was 500 mL. After 6 months since surgery, the patient

had convex facial profile and class I occlusion. For the patient with mild

midface hypoplasia, good nasal profile, and malocclusion, rib bone graft along

with Le Fort I and bilateral sagittal ramus osteotomy can be a good surgical

modality.
