Summary
The extreme lateral transcondylar/transfacetal approach effectively treated complex skull base lesions in 22 patients. This surgical technique demonstrated positive outcomes and manageable complications for challenging pathologies.
Area of Science:
- Neurosurgery
- Skull Base Surgery
Background:
- Complex skull base lesions pose significant surgical challenges.
- The extreme lateral transcondylar and transfacetal approaches offer access to difficult-to-reach pathologies.
Observation:
- Twenty-two patients with diverse complex lesions underwent treatment using these extreme lateral approaches.
- Lesions included basilar invagination, vertebral artery pathologies, aneurysms, fistulas, meningiomas, chordomas, chondrosarcomas, and paragangliomas.
- The approach was utilized independently or combined with other surgical techniques.
Findings:
- Refinements in operative technique and treatment strategies were implemented.
- Complications such as CSF leakage, meningitis, neurological deficits, and vertebral artery injury were observed and managed.
- Significant neurological deficit resolution occurred in five patients.
- The Karnofsky scores improved substantially in surviving patients, indicating enhanced functional status.
Implications:
- The extreme lateral surgical approach is a viable option for complex skull base pathologies.
- Careful surgical planning and technique are crucial for optimizing outcomes and minimizing complications.
- Further research into refining these techniques can improve patient prognosis.
