Fiber dissections were additionally performed within the third ventricle along the endoscopic route. Additionally, we present a case of ERTV in a patient with craniopharyngioma extending into the third ventricle.<\/jats:p><jats:p>\n          Results\u2003The ERTV allowed adequate intraventricular visualization along the third ventricle. The extracranial step of the surgical corridor included a bony window in the sellar floor, tuberculum sella, and the lower part of the planum sphenoidale. ERTV provided an intraventricular surgical field along the foramen of Monro to expose an area bordered by the fornix anteriorly, thalamus laterally, anterior commissure anterior superiorly, posterior commissure, habenula and pineal gland posteriorly, and aqueduct of Sylvius centered posterior inferiorly.<\/jats:p><jats:p>\n          Conclusion\u2003The third ventricle can safely be accessed through ERTV either above or below the pituitary gland. ERTV provides a wide exposure of the third ventricle through the tuber cinereum and offers access to the anterior part as far as the anterior commissure and precommissural part of fornix and the whole length of the posterior part. Endoscopic ERTV may be a suitable alternative to transcranial approaches to access the third ventricle in selected patients.<\/jats:p>","DOI":"10.1055\/a-1808-1359","type":"journal-article","created":{"date-parts":[[2022,3,24]],"date-time":"2022-03-24T23:52:27Z","timestamp":1648165947000},"page":"296-306","source":"Crossref","is-referenced-by-count":3,"title":["Endoscopic Endonasal Approach to the Third Ventricle Using the Surgical Corridor of the Reverse Third Ventriculostomy: Anatomo-Surgical Nuances"],"prefix":"10.1055","volume":"84","author":[{"given":"Ali","family":"Karadag","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Health Science University, Tepecik Research and Training Hospital, Izmir, Turkey"},{"name":"Microsurgical Neuroanatomy Laboratory, Department of Neurosurgery, Cerrahpasa Medical Faculty, Istanbul University\u2013Cerrahpasa, Istanbul, Turkey"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mahmut","family":"Camlar","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Health Science University, Tepecik Research and Training Hospital, Izmir, Turkey"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Omer Furkan","family":"Turkis","sequence":"additional","affiliation":[{"name":"Microsurgical Neuroanatomy Laboratory, Department of Neurosurgery, Cerrahpasa Medical Faculty, Istanbul University\u2013Cerrahpasa, Istanbul, Turkey"},{"name":"Department of Neurosurgery, Health Science University, Van Research and Training Hospital, Van, Turkey"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nijat","family":"Bayramli","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Health Science University, Tepecik Research and Training Hospital, Izmir, Turkey"},{"name":"Microsurgical Neuroanatomy Laboratory, Department of Neurosurgery, Cerrahpasa Medical Faculty, Istanbul University\u2013Cerrahpasa, Istanbul, Turkey"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Erik H.","family":"Middlebrooks","sequence":"additional","affiliation":[{"name":"Departments of Neurosurgery and Radiology, Mayo Clinic, Jacksonville, Florida, United States"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Necmettin","family":"Tanriover","sequence":"additional","affiliation":[{"name":"Microsurgical Neuroanatomy Laboratory, Department of Neurosurgery, Cerrahpasa Medical Faculty, Istanbul University\u2013Cerrahpasa, Istanbul, Turkey"},{"name":"Department of Neurosurgery, Cerrahpasa Faculty of Medicine, Istanbul University\u2013Cerrahpasa, Istanbul, Turkey"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"194","published-online":{"date-parts":[[2022,7,6]]},"reference":[{"issue":"03","key":"ref1","doi-asserted-by":"crossref","first-page":"334","DOI":"10.1227\/00006123-198103000-00006","article-title":"Microsurgery of the third ventricle: part I.
