In the LUMC, a specialized multidisciplinary team treats patients with meningiomas. For patients with a spheno-orbital meningioma, the resection and reconstruction is 3D virtually planned. The resection is performed using a patient specific resection guide that uniquely fits the patient anatomy. Subsequently, the bone defect is reconstructed using a patient-specific implant, reconstructing both the temporal bone and the lateral orbital wall, if indicated.
