Background: Caniopharyngiomas in spite of being benign tumors they have a high rate of recurrence of which cysts constitute major component. Ommaya Reservoir System (ORS) is a simple manoeuvre for percutaneous drainage of cysts. Aim of Study: To evaluate the efficacy of using C-arm as a guiding tool for placement of Ommaya reservoir tube in predominantly cystic recurrent craniopharyngiomas. Patients and Methods: This study included 8 patients with clinically symptomatic and radiologically confirmed recurrent craniopharyngioma with significant cystic part. These patients were treated by C-arm guided insertion of Ommaya reservoir tube. The technique is described in details. CT brain was obtained in the first post-operative night to assess the position of the tube. Post-operative clinical and radiological evaluations were compared to the pre-operative. Results: This study included 6 males and 2 females, ranging in age from 5 years to 38 years with mean age of 18.4 years. Headache was the most common presenting complaint, followed by visual impairment. All surgeries were performed with C-arm guidance and post-operative CT brain documented satisfactory position of the tube in 7 cases and only one case required second look surgery for repositioning of the tube with the same technique. Significant post-operative improvement of headache and visual symptoms were encountered in all cases due to decompression of the optic chiasm by cyst drainage. Conclusion: C-arm assisted insertion of Ommaya reservoir tube is a reliable method that can minimize the errors of free hand technique and of special value in low facility centers.
