Sir,

We really appreciate the interest in our article and the comments. [1],[2] Trapped fourth ventricle is mostly seen as a sequela in patients with ventricular shunt placed to treat a posthemorrhagic or postmeningitic hydrocephalus.[3],[4] The endoscopic aqueductoplasty and stent placement treats the isolation enlarged fourth ventricle and resolves the clinical symptomatology in the majority of cases.[5] This procedure also avoids the need for fourth ventricle shunt insertion and the associated complications.[6] However, it cannot restore the physiological reabsorption pattern which is lost in these patients. They need a working ventriculo-peritoneal (VP) supratentorial shunt to treat the hydrocephalus. Even though they usually have less shunt revisions compared with patients harboring a VP shunt and fourth ventricle shunt, they could have supratentorial shunt malfunction as well.
