Abstract

Objective : Authors analyzed clinical outcomes of cranioplasty according to the materials used for covering defects of the skulls. Methods : From January 1997 to February 2000, there were forty one patients undergone cranioplasty at our institution. We used refrigerated autogenous bone flaps in 19 cases(group A) and methyl methacrylate(MMA) in 22 cases(group B). The medical records and plain skull radiographs of the patient were reviewed. Results : There were thirty men and eleven women. Mean follow up period was 12 months(From operation to last Outpatient department follow up). The mean operative time of the group A($136.8{\pm}3$ minutes) was shorter than the group B($172.7{\pm}2$ minutes, Mann-Whitney test, p=0.001). In group A, the degree of satisfaction was good in 8 cases, fair in 10, and poor in 1. In the group B, there were fair in 13 and poor in 9. So the cosmetic result was superior in the group A(Chi-square test, p=0.00). The complications were occured in one case of flap infection in the group A and 6 in the group B(one stitch abscess, 4 infected flaps, one subgaleal hematoma). Conclusion : Cranioplasty using refrigerated autogenous bone flap showed shorter operative time, better cosmetic results, and less complication rate than those using MMA.
