The Navigation-Guided Correction of Cranial-Orbital-Facial Fibrous Dysplasia

Background: The correction of fibrous dysplasia involving cranial-orbital-facial is relatively difficult because not only the purpose of cosmetic but the goal of prevention the function of cranial nerves. Cranioal nerve decompression and prevention of injury during surgery are most important for patients with fibrous dysplsia involving the sphenoid wing. Material 20 cases of the cranial-orbital-facial fibrous dysplasia are presented in our series from January 2005 to March 2013. Their average age was 14 ± 2.5 years(10∼18years). 13 of 20 cases involved multiple portions including the foremen of optic nerve.

Method: All cases in this series are diagnoised with three dimentional CT scanning and magnetic resonance imaging. Intracranial procedure was applied for all 20 cases under the guide of computer-assisted navigation for precise correction and recongstruction of cranial base and the orbital also cranial nerve decompression as well. Pre-operative analyzing and designing of the correction is applied.

Result: The cosmetic deformity were corrected and the cranial nerve were decompressed successfully in all cases with excellent result.

Conclusion: Navigation-guided correction of cranial-orbital-facial fibrous dysplasia shows great value in improving the accuracy and reducing operation risk and restoring facial symmetry.
