Abstract:
Objective To summarize the clinical effect of individualized cranioplasty with different materials. Method The clinical data of 75 patients with skull defect were analyzed retrospectively. Ultrathin cranial CT and three-dimension reconstruction were done to delineate the shape and contour of cranial defect. The templet for repair was fabricated with methyl silicone rubber, bone cement or titanium mest according to the condition of the bone defect with laser rapid prototyping technique. With patient's consent, the individualized templet was implanted to repair the cranial defect. Results Methyl silicone rubber or bone cement were used for 40 of 75 patients to fill the defects, and in the other 35 patients titanium mesh was used to cover the defects with overlapping edges. The patches matched cranial defect perfectly without the necessity of revision. The average operation time was 45 minutes. Perfect or excellent cosmetic results was obtained in 63 of the 75 patients (84%). Postoperative complications were as follows: 5 patients complained of headache, which disappeared in there months. Collection of fluid under the scalp was found in 12 patients, among them the fluid was Absorbed 10 days after operation in 8 cases without any treatment, while in 3 patients it disappeared after suction for 1-4 times. In the remaining one patient, the bone cement templet was removed due to infection, and a titanium mesh was implanted one year later. Loosening and displacement of the templet occurred in 2 patients, and silk sufures were used for fixation in both patients. In these two patients, the templet became stable 3 months later, and in the other titanium was used for repair one year later. The incidence of complications was signifieantly different between inlay and onlay methods of repair (P
