We discuss the technical nuances of a modified MPT approach, the extradural MPT approach (eMPTa), for the treatment of a giant intracranial aneurysm (GIA) arising from the paraclinoid carotid artery.<\/jats:p>\n<\/jats:sec>\n\nCase Description: <\/jats:title>\nA 44-year-old female presented with facial hypoesthesia and third cranial nerve palsy. Further investigations revealed the presence of a 27 mm aneurysm arising from the communicating segment of the internal carotid artery. The patient underwent surgical clipping through an extradural MPT craniotomy and combined anterior clinoidectomy. Postoperative angio-computed tomography demonstrated complete aneurysm occlusion and patency of the parent vessels. The patient recovered fully from her previous deficits.<\/jats:p>\n<\/jats:sec>\n\nConclusion: <\/jats:title>\nThe skull base drilling, interdural dissection, and anterior clinoidectomy are key steps during the eMPTa that optimizes the use of the extradural corridor. Such adaptations are enough to improve the surgical maneuverability along the paraclinoid region and adapt the MPT suitability for the treatment of complex GIA.<\/jats:p>\n<\/jats:sec>","DOI":"10.25259\/sni_368_2020","type":"journal-article","created":{"date-parts":[[2020,11,11]],"date-time":"2020-11-11T06:19:25Z","timestamp":1605075565000},"page":"382","update-policy":"https:\/\/doi.org\/10.25259\/crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Extradural minipterional approach for giant intracranial aneurysms"],"prefix":"10.25259","volume":"11","author":[{"given":"Rafael","family":"Martinez-Perez","sequence":"first","affiliation":[{"name":"Department of Neurosurgery, University of Colorado, Aurora, Colorado, United States"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Asterios","family":"Tsimpas","sequence":"additional","affiliation":[{"name":"Department of Surgery, Advocate Illinois Masonic Center, Chicago, Illinois, United States,"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Holger","family":"Joswig","sequence":"additional","affiliation":[{"name":"Department of Cerebrovascular and Skull Base Surgery Neurosurgery, Instituto de Neurocirug\u00eda Dr. Alfonso Asenjo, Providencia, United States."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Victor","family":"Hernandez-Alvarez","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Universidad de Santiago de Chile, Chile, Santiago, United States."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jorge","family":"Mura","sequence":"additional","affiliation":[{"name":"Department of Cerebrovascular and Skull Base Surgery Neurosurgery, Instituto de Neurocirug\u00eda Dr. Alfonso Asenjo, Providencia, United States."}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"10894","published-online":{"date-parts":[[2020,11,11]]},"reference":[{"key":"10.25259\/SNI_368_2020\/ref-1","doi-asserted-by":"crossref","first-page":"S7","DOI":"10.1227\/NEU.0000000000000193","article-title":"Advances in open microsurgery for cerebral aneurysms","volume":"74","author":"Davies","year":"2014","journal-title":"Neurosurgery"},{"key":"10.25259\/SNI_368_2020\/ref-2","first-page":"256","article-title":"The minipterional craniotomy: Technical description and anatomic assessment","volume":"61","author":"Figueiredo","year":"2007","journal-title":"Neurosurgery"},{"key":"10.25259\/SNI_368_2020\/ref-3","doi-asserted-by":"crossref","first-page":"125","DOI":"10.1055\/s-0033-1359302","article-title":"The meningo-orbital band: Microsurgical anatomy and surgical detachment of the membranous structures through a frontotemporal craniotomy with removal of the anterior clinoid process","volume":"75","author":"Fukuda","year":"2014","journal-title":"J Neurol Surg B Skull Base"},{"key":"10.25259\/SNI_368_2020\/ref-4","doi-asserted-by":"crossref","first-page":"295","DOI":"10.2176\/nmc.22.295","article-title":"Surgical approaches to the cavernous sinus.
