Summary
Endoscopic keyhole surgery offers a minimally invasive option for intracranial epidermoids, achieving comparable outcomes to traditional methods. This approach provides effective tumor resection with manageable complications for patients.
Area of Science:
- Neurosurgery
- Minimally Invasive Surgery
- Endoscopic Techniques
Background:
- Keyhole endoscopic approaches are increasingly utilized in neurosurgery.
- Intracranial epidermoids are suitable for keyhole surgery due to their encapsulated, avascular nature.
Purpose of the Study:
- To evaluate the efficacy and outcomes of the endoscopic keyhole approach for intracranial epidermoid excision.
- To present experience with this minimally invasive technique across various lesion locations.
Main Methods:
- Retrospective study of 26 patients undergoing keyhole endoscopic epidermoid excision (July 2015 - December 2019).
- Analysis of patient demographics, clinical presentation, imaging, surgical outcomes, and postoperative complications.
- Follow-up assessment of symptom improvement and complication resolution.
Main Results:
- Gross total resection achieved in 73.1% of cases; near total in 19.2%; subtotal in 7.7%.
- Significant symptom improvement noted for trigeminal neuralgic pain (83%) and headache (66.7%).
- Common complications included temporary facial and cranial nerve paresis; no re-surgeries were required.
Conclusions:
- Endoscopic keyhole excision is a viable alternative to conventional microsurgery for intracranial epidermoids.
- Careful patient selection is crucial for optimizing surgical and functional outcomes.
- This minimally invasive approach demonstrates comparable efficacy and safety profiles.
