This study analyzes the results of surgical treatment in 39 patients with the Crouzon syndrome. Early frontoorbital advancement and craniectomy were universally successful in relieving raised intracranial pressure and in reducing ocular proptosis. However, definitive cosmetic correction was not achieved, and early cranial surgery was not able to prevent the development of midface hypoplasia.
Thirty-two midfacial advancements have been performed in 30 patients. Sixteen patients had sufficient follow-up data for more than 2 years postoperatively. In all patients, a satisfactory early postoperative result was achieved. In the long-term follow-up group, 11 patients have maintained a satisfactory appearance, while 5 have developed recurrent deformity. Analysis shows this to be associated with a younger age at operation and continued mandibular growth. Frontofacial advancement in adults achieves good long-term results but is associated with a higher incidence of complications.
