Fenestration methods for Sylvian arachnoid cysts--endoscopy or microsurgery

Area of Science:

• Neurosurgery
• Cranial Surgery
• Minimally Invasive Surgery

Background:

• Sylvian arachnoid cysts (SACs) are the most common intracranial arachnoid cysts.
• Fenestration is a primary treatment for SACs, with endoscopic and microsurgical techniques available.
• Comparative data on the safety and efficacy of these fenestration methods are crucial for clinical decision-making.

Purpose of the Study:

• To compare the clinical outcomes, safety, and efficacy of microsurgical versus endoscopic fenestration for Sylvian arachnoid cysts.
• To evaluate complication rates and the need for reoperation between the two surgical approaches.

Main Methods:

• Retrospective study of 29 patients undergoing cysto-cisternostomy for SACs.
• Patients were treated by the same surgical team using either microsurgical or neuroendoscopic fenestration.
• Clinical and radiological success, along with complication rates, were assessed for both techniques.

Main Results:

• Thirteen patients underwent microsurgery, and 16 had endoscopic fenestration.
• Both groups achieved full clinical and radiological success with no need for reoperation.
• Complication rates were 23% for microsurgery and 47% for endoscopic fenestration, with no statistically significant difference.

Conclusions:

• Neither microsurgical nor endoscopic fenestration demonstrated superiority in terms of efficacy for SACs.
• Microsurgical fenestration appears to be a safer option, with a lower complication rate observed in this study.
• Further analysis suggests microsurgical fenestration may offer a more controlled and safer approach compared to endoscopic methods for SACs.
