Welcome to der-nerv.com. On the following pages, you will find comprehensive information regarding neurosurgically relevant diseases, injuries, diagnostic pathways, and surgical management of the nervous system, including:
- The Brain & Cranium (Neurocranium)
- The Spinal Cord & Spine
- Peripheral Nerves & Brachial Plexus (in Adults and Children)
- Facial Nerve Palsy, Facial Hemispasm, and Trigeminal Neuralgia
We present selected clinical examples from our practice in anonymized form. The objective is to provide patients and colleagues with an overview of neurosurgical conditions and contemporary, evidence-based management strategies. Every patient requires individual evaluation to tailor the optimal treatment plan.
