    Abstract:
    OBJECTIVE: The objective of this study is to establish which treatment is the best operative intervention for arachnoid cyst. MATERIALS AND METHODS: We reviewed a series of 209 cases with arachnoid cysts focusing on the effectiveness and safety. The cysts were treated with several surgical procedures including open surgery for fenestration, endoscopic fenestration, or cystoperitoneal shunting. RESULTS: Follow-up imaging studies showed that 176 out of 209 arachnoid cysts (84.2%) reduced in size during a mean postoperative follow-up period of 6.9 years (range, 1 to 14 years). Although a cystoperitoneal shunt was the best method for early achieving an obliteration of the sylvian cyst (89%), it had the danger of shunt dependency (42%) in addition to four early complications. Although endoscopic fenestration tended to be less effective in reducing the size of a sylvian cyst, it was safe and particularly effective in completely obliterating a suprasellar, quadrigeminal, and prepontine cyst. CONCLUSION: Although the shunt for arachnoid cyst can get the more rapid good radiological outcome, the shunt-related complication and dependency would be hazardous. We suggest that endoscopic or reduced open procedures offer the advantage of avoiding a large craniotomy or the known complications of a cystoperitoneal shunt in treatment of arachnoid cysts. We could get the nearly same surgical outcome without shunt complications with endoscopic or open procedures.
