Objective:
The object of this study was to analyze the therapeutic effects of microsurgical excision in cases with the large or giant cerebellopontine angle meningioma.
Methods:
We retrospectively analyzed the 56 patients who suffered from the large or giant cerebellopontine angle meningioma and underwent the microsurgical therapy, for which the suboccipital-retrosigmoidal approach was adopted in 38 cases, the temporal-occipital craniotomy, presigmoidal approach in 6 cases, the temporal-occipital craniotomy, inferotemporal tentorium cerebelli approach in 8 cases, and the temporal-occipital craniotomy, supratentorial or infratentorial allied approach in 4 cases.
Results:
The tumors of 44 cases were all resected (Simpson I, II), with a total resection rate of 78.6%, and there was no operative mortality. After surgery, symptoms improved in 40 cases and remained unchanged in 10 cases. Among 54 cases, recrudescence was seen in 2 cases (3.7%) and being able to take care of themselves in 50 cases (92.6%) at 6 months through 6 years follow-up after surgery.
Conclusion:
A rationally selected surgical approach, a microscopic technology applied in the operation to appropriately treat and protect vein, nerve and brain stem, which can ideally excise the tumors, together can increase the survival ability of patients.
Insights
Microsurgical excision effectively treats large or giant cerebellopontine angle meningiomas, achieving high resection rates and improving patient outcomes with minimal recurrence. This approach enhances survival and quality of life.
Area of Science:
- Neurosurgery
- Oncology
Background:
- Large or giant cerebellopontine angle meningiomas pose significant surgical challenges.
- Microsurgical techniques are crucial for managing complex brain tumors.
Purpose of the Study:
- To evaluate the therapeutic efficacy of microsurgical excision for large or giant cerebellopontine angle meningiomas.
- To analyze surgical approaches and patient outcomes.
Main Methods:
- Retrospective analysis of 56 patients with large or giant cerebellopontine angle meningiomas.
- Utilized various microsurgical approaches including suboccipital-retrosigmoidal and temporal-occipital craniotomies.
- Assessed tumor resection rates, operative mortality, symptom improvement, and long-term outcomes.
Main Results:
- Achieved a total resection rate of 78.6% (Simpson I, II) in 44 cases.
- No operative mortality was observed.
- Symptom improvement in 40 cases; 92.6% of patients were self-sufficient at follow-up (6 months to 6 years).
Conclusions:
- Rationally selected surgical approaches combined with microscopic technology are key to successful tumor excision.
- Microsurgical techniques protect vital neurovascular structures, improving patient survival and quality of life.
