Skull Defect Repairing - Cranioplasty | Neurosurgical Clinic of University Hospital Rechts der Isar Munich

The cranioplasty program at the University Hospital Rechts der Isar (MRI) in Munich is defined by its fusion of high-level neuro-reconstructive surgery and advanced material science. At this academic center, repairing a skull defect is approached as a critical restoration of cerebral homeostasis, normalizing the intracranial pressure and blood flow that is often disrupted when a portion of the skull is missing. The clinic specializes in treating complex defects resulting from previous trauma, decompressive craniectomies, or tumor resections, utilizing a symptom-oriented philosophy that aims to alleviate the syndrome of the trephined (dizziness, headache, and cognitive decline) alongside aesthetic restoration. A cornerstone of the methodology is the use of patient-specific implants (PSI) designed via computer-aided design and manufacturing (CAD/CAM). Before the procedure, the patient undergoes a high-resolution, thin-slice CT scan, which is transformed into a 3D digital model of the skull. This allows the neurosurgical team to pre-plan the exact curvature and thickness of the implant to achieve perfect symmetry. Depending on the patient's biological requirements and the location of the defect, the clinic uses a range of biocompatible materials, including polyetheretherketone (PEEK), which mimics the elasticity of human bone, and titanium mesh, or, in specific cases, specialized bioactive ceramics that promote the integration of surrounding tissue. The surgical execution at the Munich clinic is aided by 3D neuronavigation, allowing for the precise positioning of the implant relative to the underlying brain tissue and the meninges. This is particularly crucial in secondary cranioplasties, where extensive scarring from previous operations is present. Surgeons here prioritize the meticulous dissection of the scalp layers to preserve blood supply and ensure optimal wound healing, often working in tandem with the hospital’s plastic surgery specialists for complex soft-tissue coverage. The use of piezo-surgical tools, which use ultrasonic vibrations to cut bone while sparing soft tissue, ensures that the margins of the existing skull are prepared for the implant with minimal trauma. Post-operative recovery at University Hospital Rechts der Isar is managed through a sophisticated neuro-monitoring protocol. Patients are monitored for changes in intracranial pressure and cerebrospinal fluid (CSF) dynamics, ensuring that the brain adapts correctly to the restored rigid enclosure. Because the clinic is part of a leading University Hospital, patients benefit from a multidisciplinary environment where neurosurgeons, neuroradiologists, and specialized rehabilitation therapists collaborate. This ensures that the structural repair of the skull is coupled with a functional recovery plan that focuses on resolving neurological symptoms and protecting the brain's delicate environment in the long term.
