Abstract:
Objective To explore the microsurgical treatment of the fourth ventricular tumors. Methods A total of 29 cases of the fourth ventricular tumors were given microsurgical treatment from January 2000 to June 2003 in this hospital. In 5 cases the tumor was located close to the cortex with the superior vermis involvement and the microsurgical operation was performed through the cerebellar vermis. The remaining 24 cases underwent microsurgical resection of tumor through the cerebellomedullary fissure approach. Results A total resection was achieved in 23 cases, and a subtotal resection in 6 cases. Postoperative complications included 2 cases of hemorrhage of the upper digestive tract, 1 case of mutism, 1 case of hematoma of the fourth ventricular, 1 case of epidural hematoma remote from surgical site, and 1 case of irregular breath. Follow-up surveys in 19 cases for 3~12 months (mean, 5.5 months) revealed no tumor recurrence. Conclusions Preoperative proper differentiating characters of tumors, clarifying the position of tumors' basal part, selecting appropriate surgical approach, and understanding microanatomy of the fourth ventricular are the key to successfully complete the procedure.
