The goal of this study was to describe the outer arachnoid envelope around the olfactory bulb, which plays a significant role in approach-related injury of the nerve.<\/jats:p><jats:p>\n          Methods\u2003A total of 20 fresh human cadaveric heads were examined. Five cadaveric heads were used to describe a gross overview of the topographic anatomy of the outer arachnoid cover of the olfactory bulb. In 15 cadaveric heads, endoscopic surgical approaches were performed to examine the in situ undisrupted anatomy of the outer arachnoid around the olfactory bulb. Four cadaveric heads were used for the lateral subfrontal approach, 5 heads for the medial subfrontal approach, 3 heads for the median subfrontal approach, and 3 heads for the anterior interhemispheric approach.<\/jats:p><jats:p>\n          Results\u2003The outer arachnoid membrane of the frontal lobe attaches the olfactory bulb strongly to the above lying olfactory sulcus. Only the most rostral portion of the olfactory bulb became slightly detached from the frontal lobe. The outer arachnoid forms a decent protrusion around the tip of the olfactory bulbs. The fila olfactoria have their own outer arachnoid cover as a continuation of the same layer of the olfactory bulb. The effect of brain retraction and manipulation forces on the olfactory bulb and the role of the arachnoid membranes located here were visually analyzed and described in detail through the four different neurosurgical approaches we performed.<\/jats:p><jats:p>\n          Conclusion\u2003The results of our observations provide important anatomical details for preserving the sense of smell during neurosurgical procedures.<\/jats:p>","DOI":"10.1055\/a-2249-7710","type":"journal-article","created":{"date-parts":[[2024,1,19]],"date-time":"2024-01-19T23:59:13Z","timestamp":1705708753000},"page":"169-176","source":"Crossref","is-referenced-by-count":0,"title":["Anatomy and Microsurgical Relevance of the Outer Arachnoid Envelope around the Olfactory Bulb Based on Endoscopic Cadaveric Observations"],"prefix":"10.1055","volume":"86","author":[{"given":"Peter","family":"Kurucz","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Friedrich-Alexander-University Erlangen-Nuremberg, Erlangen, Germany"},{"name":"Department of Neurosurgery, Katharinenhospital, Klinikum Stuttgart, Stuttgart, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Oliver","family":"Ganslandt","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Katharinenhospital, Klinikum Stuttgart, Stuttgart, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Michael","family":"Buchfelder","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Friedrich-Alexander-University Erlangen-Nuremberg, Erlangen, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sasan Darius","family":"Adib","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, University of Tuebingen, Tuebingen, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Laszlo","family":"Barany","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Friedrich-Alexander-University Erlangen-Nuremberg, Erlangen, Germany"},{"name":"Laboratory for Applied and Clinical Anatomy, Department of Anatomy, Histology and Embryology, Semmelweis University, Budapest, Hungary"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"194","published-online":{"date-parts":[[2024,7,8]]},"reference":[{"issue":"02","key":"ref1","doi-asserted-by":"crossref","first-page":"133","DOI":"10.1007\/BF01627573","article-title":"Blood supply of the olfactory nerve.
