BackgroundThe postoperative ventricular adhesion after resection of central nervous system tumors can obstruct physiologic cerebrospinal fluid (CSF) circulation and cause temporal horn entrapment. The surgical goal is to restore physiologic flow of CSF. The authors reviewed their database to report their experience with endoscopic fenestration for treating entrapped temporal horn caused by atrial adhesions. All endoscopic operations performed from February 2015 to December 2016 were reviewed.Case DescriptionThree patients developed temporal horn entrapment after tumor resection. Fenestration was successful in all patients, with a subsequent stomy of the septum pellucidum. Follow-up magnetic resonance imaging 1 year later showed a patent reduction of the entrapped horn.ConclusionsEndoscopic fenestration is an option in the treatment of entrapped temporal horns. However, more experience is required to recommend it as the treatment of choice.Copyright © 2018 Elsevier Inc. All rights reserved.
