Summary
Reinforcing multilayer repairs for skull base cerebrospinal fluid leaks with autologous bone grafts is effective. Harvesting a monocortical mastoid cortex graft is simple and does not increase patient morbidity.
Area of Science:
- Neurosurgery
- Otolaryngology
- Skull Base Surgery
Background:
- Cerebrospinal fluid (CSF) leaks and encephaloceles in the lateral skull base pose significant surgical challenges.
- Multilayer repair techniques are commonly employed but may require reinforcement for optimal outcomes.
