What is Neurofibroma?
Neurofibromas are benign tumors of peripheral nerves. They arise from the cells that form and support the nerve sheath: Schwann cells, fibroblasts, and perineural cells.
These tumors infiltrate the nerve and disrupt the sheaths of individual fibers. The most commonly affected nerve is the vestibulocochlear nerve, which transmits sound and balance information to the brain from the inner ear.
Neurofibromas can be single or multiple. When multiple, they are associated with neurofibromatosis type I, a genetic disorder also known as von Recklinghausen disease.
Symptoms depend on the location and size of the tumor. Neurofibromas typically are painless, slow-growing masses, and may cause no symptoms.
At UPMC, the preferred surgical treatment for neurofibroma of the skull base is the Endoscopic Endonasal Approach (EEA). This innovative, minimally invasive technique uses the nose and nasal cavities as natural corridors to access hard-to-reach or previously inoperable tumors. Benefits of EEA treatment include:
- No incisions to heal
- No disfigurement
- Faster recovery time
