Objective: Decompressive craniectomy is an established method for decreasing intracranial pressure in cases of severe cerebral swelling. This study examines different surgical materials and techniques of repair with regard to inherent cost and surgical risk with a particular focus on infectious complications.

Method: A retrospective analysis was conducted of 296 patients who underwent decompressive craniectomy at our institution between january 2003 and june 2013. Cranioplasty was performed in 286 cases using autologous bone graft in 200, freehand modeled acrylic graft in 73 and industrial PSI acrylic implant in 13 cases. Median follow-up was 43,3 months. 59 patients were additionally treated with a ventricular-peritoneal shunt, 8 of which were performed together with cranioplasty, 51 in a second operation.

Results: In 21% of cases (n= 62) reoperation became necessary for reasons of dislocation, hemorrhage or infection. 20% of the autologous bone grafts, 13% of freehand acrylic and 15% of PSI grafts required revision. Within the follow-up period infectious complications were seen in 8% in all 3 groups. In 48% (n= 18) MR revealed airless paranasal sinuses or mucosal thickening on the trephined side, however microbiological work-up revealed Stapylococcus areus as the main pathogen. The risk of infection showed a tendency to increase when cranioplasty was combined with ventriculoperitoneal shunting (2/8 versus 8/51).

Conclusions: Cranioplasty can be safely performed using all three examined techniques. The rates of infectious complications are comparable between groups. Concomittant VP-shunting shows a tendency towards an increase of infectious complications. Autologous bone grafts are simple to perform and cost effective.
