Summary
This study presents a surgical technique for spontaneous cerebrospinal fluid (CSF) leaks of the temporal bone, achieving an 87.7% long-term success rate. Comprehensive perioperative management and surgical approaches improve outcomes for this condition.
Area of Science:
- Neurosurgery
- Otolaryngology
- Cerebrospinal Fluid Dynamics
Background:
- Spontaneous cerebrospinal fluid (CSF) leaks of the temporal bone are idiopathic, without trauma or congenital defects.
- Effective management necessitates thorough perioperative risk assessment and surgical strategies addressing all potential leak pathways.
Purpose of the Study:
- To detail a surgical technique for spontaneous CSF otorrhea addressing multiple potential leakage routes.
- To describe perioperative management protocols for patients undergoing CSF leak repair.
Main Methods:
- A middle cranial fossa approach was employed for CSF leak repair in 65 patients.
- Surgical outcomes were evaluated based on the described techniques and perioperative management.
Main Results:
- All 65 patients demonstrated short-term success in CSF leak repair.
- A long-term success rate of 87.7% was achieved with no major complications.
- Preoperative confirmation included beta trace protein-positive CSF otorrhea or encephalocele on imaging.
Conclusions:
- A holistic treatment approach for spontaneous temporal bone CSF leaks is crucial.
- Surgical techniques that encompass all potential CSF leakage routes enhance both short- and long-term outcomes.
