Summary
The infratentorial-supracerebellar (ITSC) approach offers a safe and effective surgical option for resecting intrinsic brainstem lesions. This method demonstrated successful tumor removal and improved patient outcomes in a study of 16 individuals.
Area of Science:
- Neurosurgery
- Oncology
- Neurology
Background:
- Surgical treatment of intrinsic brainstem lesions presents significant challenges.
- The infratentorial-supracerebellar (ITSC) approach is explored for accessing ponto-mesencephalic lesions.
Purpose of the Study:
- To evaluate the efficacy and safety of the ITSC approach for resecting intrinsic ponto-mesencephalic lesions.
- To assess the impact of the surgical approach on patient neurological function and symptoms.
Main Methods:
- A retrospective review of 16 patients undergoing ITSC approach for intrinsic brainstem lesions.
- Two specific ITSC variations were utilized: transcollicular for mid-brain and infra-trochlear for ponto-mesencephalic lesions.
Main Results:
- Complete resection of all 16 lesions was achieved with no mortality or bleeding recurrence.
- Significant improvement in neurological deficits and ocular symptoms was observed in patients with mid-brain and ponto-mesencephalic lesions.
- Modified Rankin Scale scores improved from 1.8 to 1.3 for mid-brain lesions and 3.75 to 2.5 for ponto-mesencephalic lesions.
Conclusions:
- The ITSC transcollicular and infra-trochlear approaches provide wide operative access to ponto-mesencephalic lesions.
- These ITSC approaches minimize functional damage to surrounding structures, offering a viable surgical strategy.
