Objective To investigate and evaluate the effectiveness ofneuroendoscopic therapy on patients with cerebral hemispheres convex arachnoid cysts.Methods Thirteen patients with cerebral hemispheres convex arachnoid cysts (close to lateral ventricle or cistern),admitted to and accepted endoscopic cystoventriculostomy or cystocisternotomyin our hospital from September 2007 to July 2011,were chosen in our study; their clinical data,including clinical and neuroradiological presentations,surgical indications,surgical techniques,complications,and clinical and neuroradiological follow-up results,were retrospectively analyzed.Results The cysts were reduced in size in all 13 patients (100%).The symptoms disappeared in 9 and improved in 4 after the operation,with a clinical improvement rate reaching 100%.One patient had asymptomatic subdural hydroma after the operation.Conclusion Endoscopic fenestration is an effective treatment for patients with cerebral hemispheres convex arachnoid cysts close to lateral ventricle or cistern,and can be the first surgical choice for these cysts.

<p><b>OBJECTIVE</b>To investigate and evaluate the effectiveness of neuroendoscopic therapy for arachnoid cysts of middle cranial fossa.</p><p><b>METHODS</b>From January 2004 to June 2009, 32 patients with arachnoid cysts of middle cranial fossa who were treated with endoscopic cystocisternal fenestration were retrospectively analyzed. There were 21 male patients and 11 female patients, aged from 6 months to 39 years. The clinical and neuroradiological presentation, indications, surgical technique, complications, and clinical and neuroradiological follow-up were analyzed.</p><p><b>RESULTS</b>The cysts were reduced in size in 20 patients and completely disappeared in 4 patients. For the 27 patients with symptoms before operation, the symptoms disappeared in 8 cases and improved in 17 cases after operation. There were asymptomatic subdural hydroma in 4 patients, intracranial infection and incision cerebro-spinal fluid leakage in 1 patient respectively. The complication incidence rate was 18.8%.</p><p><b>CONCLUSIONS</b>Endoscopic fenestration is an effective treatment for symptomatic arachnoid cysts of middle cranial fossa and could be performed as the first surgical choice for these patients.</p>
