Currently, endoscopic surgery to break up arachnoid cysts of cerebrospinal fluid is the most important treatment method. This surgical method is minimally invasive and effective because people use endoscopy to open the cyst wall to communicate with the subarachnoid space, or with the ventricles.

Cerebrospinal fluid arachnoid cysts are benign tumors, accounting for about 1% of intracranial lesions. Laryngeal mask anesthesia is the anesthesia technique used in endoscopic surgery to remove cerebrospinal fluid arachnoid cysts.
