[Application of computer-aided surgery in fibrous dysplasia of cranio-maxillofacial bone].

PURPOSE: To evaluate the effect of computer-aided surgical techniques in surgical treatment of cranio-maxillofacial fibrous dysplasia.

METHODS: Twenty-two patients from January 1999 to December 2012 with cranio-maxillofacial fibrous dysplasia were treated in our department. According to the patients' specific conditions, surgeons designed surgical programs, and used computer-assisted surgical techniques to produce skull model and navigation template individually. The effects after surgery were evaluated.

RESULTS: Twenty-two patients with resection of the bone lesions restored facial symmetry partially. The patients were followed up for 3 to 36 months, and the treatment effects were satisfactory.

CONCLUSIONS: With preoperative planning, intraoperative navigation and postoperative prediction, computer-aided surgery shows its great value in improving the accuracy of cranio-maxillofacial surgery, shortening operating time and restoring facial symmetry. It is regarded as a valuable and safe surgical technique in cranio-maxillofacial surgery. Supported by Beijing Natural Science Foundation (7112124).
