Supplementary Material for: Transcortical Transventricular Endoscopic Approach and Ommaya Reservoir Placement for Cystic Craniopharyngioma

The treatment of craniopharyngioma is varied. It ranges from radical excision to direct radiotherapy. As the morbidity of excision is high, more conservative approaches are used. Placement of a catheter and reservoir is one such option for cystic craniopharyngiomas. The positioning of catheters has been performed by various means. A method of endoscopic reservoir catheter placement is described. Three children with ages ranging from 5 to 12 years presented with clinical features of raised intracranial pressure. They did not have vision impairment. Imaging showed a predominantly cystic craniopharyngioma extending into the third ventricle with hydrocephalus. All underwent precoronal burr hole, transcortical transventricular endoscopic biopsy of craniopharyngioma, and Ommaya reservoir placement. There were no complications. All children did well after surgery and did not require further cyst aspiration.
