Background:
The resection of the jugum (planum) sphenoidale meningioma (JSM) is challenging, and there is a scarcity of available data in the literature. This study aimed to describe the surgical management and long-term outcome of jugum sphenoidale meningioma.
Methods:
This was a retrospective, single-center, cohort study of 91 JSM patients treated in our department from 2005 to 2022. All the included patients have undergone surgical treatment. Clinical, radiologic, and surgical data were extracted with specific attention to the age at onset, family history, duration from symptoms to diagnosis, clinical presentation, quality of excision, recurrence, and treatment outcome.
Results:
WHO grade I and grade II meningioma were 83.5% (n = 76) and 16.5% (n = 15) respectively. Fronto-lateral 42.9% (n = 39) and pterional approaches 57.1% (n = 52) were the 2 major surgical approaches used for the management of planum sphenoidale meningioma. Twelve patients needed emergency surgical treatment at admission: 4 (4.4%) External CSF Shunt and 8 (8.8%) VP-Shunt. We have found a statistically significant (P = 0.032) association between the quality of excision and the risk of recurrence. The GTR (Hazard ratio = 1) of the planum meningioma protects the patient from recurrence within 60 months of follow-up. Postoperative complications encountered were CSF-Leak in 2.2%, Meningitis 4.4%, surgical site infection 2.2%, and surgical site hematoma 3.3%. The overall postoperative favorable outcome was 68.1% (n = 62).
Conclusions:
The pterional approach has allowed the achievement of GTR for jugum sphenoidale meningioma with protective odds from recurrence risk.
Insights
Surgical resection of jugum sphenoidale meningioma (JSM) is challenging. The pterional approach offers protective odds against JSM recurrence, with gross total resection (GTR) significantly reducing risk within 60 months.
Area of Science:
- Neurosurgery
- Oncology
- Neuropathology
Background:
- Jugum sphenoidale meningioma (JSM) resection presents significant surgical challenges.
- Limited literature exists on the long-term outcomes of JSM management.
Purpose of the Study:
- To describe the surgical management strategies for JSM.
- To evaluate the long-term outcomes following JSM resection.
Main Methods:
- Retrospective, single-center cohort study of 91 JSM patients (2005-2022).
- Data extracted on demographics, clinical presentation, surgical approach, excision quality, recurrence, and outcomes.
- Analysis focused on factors influencing recurrence and overall success.
Main Results:
- 83.5% WHO grade I, 16.5% WHO grade II meningiomas.
- Pterional approach (57.1%) was more common than fronto-lateral (42.9%).
- Gross total resection (GTR) significantly reduced recurrence risk within 60 months (P=0.032).
- Favorable postoperative outcome in 68.1% of patients.
- Complications included CSF-leak (2.2%), meningitis (4.4%), SSI (2.2%), and hematoma (3.3%).
Conclusions:
- The pterional approach facilitates GTR for JSM.
- Achieving GTR is crucial for minimizing recurrence risk in JSM patients.
