SURG-40. SINGLE-STAGE RECONSTRUCTION FOLLOWING ONCOLOGIC RESECTION OF BRAIN TUMORS WITH SKULL INVASION

Le résumé fourni par la source

Abstract BACKGROUND: Craniectomies requiring skull reconstruction are indicated following oncological resection of masses involving the underlying brain and/or skull. Immediate cranioplasties have previously been performed using suboptimal hand-bending or molding techniques using ‘‘off – the – shelf’’ products. Today with computer – aided design, customized craniofacial implants have become widely available for personalized reconstruction of resected bone and soft tissue. We present the largest series to date of single stage reconstruction using alloplastic biomaterials in consecutive patient series with oversized customized implants.In total, 56 patients underwent resection of skull neoplasms and subsequent cranioplasty reconstruction using customized implants. The most common neoplasms were meningiomas (39%). The most common complications seen among patients were dehiscence – (7%), and extrusion of implant – (3.5%). There was no significant difference in the incidence of postoperative complications between patients who had postoperative chemotherapy/radiotherapy versus those that did not (22.2% versus 13.1%, P 0.39). One-year follow-up revealed acceptable cranial contour and symmetry in all 56 cases.
