Complex, Computer Assisted Skull Reconstruction Using Patient Specific Implants after Resection of an Intraosseous Meningioma – A Case Report

Background: Resection defects of the skull have long been reconstructed using autogenously and alloplastic materials[1]. Complex reconstructions of the orbit have been reported to benefit from patient specific implants [2].Due to new algorithms planning procedures for these implants have recently improved significantly. Rapid production methods such as selective laser melting and rapid prototyping have now been introduced into the clinical routine[3]. Case Report: We report a case of a 49-year old woman presenting with a recurrence of a previously surgically resected meningioma. The lesion had grown from the lateral sphenoidal bone towards the orbit and compromised her appearance and vision. The surgical procedure included resection and alloplastic reconstruction using a patient specific implant (PSI) planned by our department and manufactured by selective laser melting (SLM). We focus on the process of implant planning and its interaction with the production process. Conclusion: Patient specific implants provide the treating surgeons with a superior method of anatomically correct, alloplastic skull reconstruction, which is able to contribute to an improved clinical outcome.
