Abstract
Objective:
We evaluated the long-term outcomes from a single neurosurgeon and otolaryngologist team using a specific operative protocol for repair and postoperative evaluation.
Design:
The charts of patients undergoing endoscopic endonasal repair of meningoencephaloceles (MECs) and cerebrospinal fluid (CSF) leaks were retrospectively reviewed from 2015 - 2023. Intraoperative steps of the repair and reconstruction were analyzed. Patients' postoperative assessments and complications were analyzed.
Setting:
Loyola University Medical Center’s electronic medical record database
Participants:
43 patients (32 female) between 11-81 years old.
Main Outcome Measures:
Long-term outcomes of patients that underwent endoscopic endonasal repair of MECs and CSF leaks by a single team and protocol. We hypothesized that there would be minimal complications and no recurrences, requiring secondary operation.
Results:
The most common site for MECs was the cribriform plate. Lumbar drain opening pressures ranged from 10 to 35 cmH2O with 18 out of 34 patients having the lumbar drain removed immediately postoperatively. The median hospital stay was 3 days. The average length of follow up was 3.8 years. No recurrences or secondary operations were noted in all patients. One patient had a sinonasal infection that was successfully treated. 8 patients were noted to have venous stenosis and underwent further evaluation.
Conclusion: This study represents one of the largest long-term analyses of outcomes by a single team. Our specific protocol for the endoscopic endonasal repair of anterior skull base MECs and CSF leaks is safe and effective. These patients should be evaluated and treated for elevated intracranial pressure following the repair.
期刊介绍:
The Journal of Neurological Surgery Part B: Skull Base (JNLS B) is a major publication from the world''s leading publisher in neurosurgery. JNLS B currently serves as the official organ of several national and international neurosurgery and skull base societies.
JNLS B is a peer-reviewed journal publishing original research, review articles, and technical notes covering all aspects of neurological surgery. The focus of JNLS B includes microsurgery as well as the latest minimally invasive techniques, such as stereotactic-guided surgery, endoscopy, and endovascular procedures. JNLS B is devoted to the techniques and procedures of skull base surgery.
