However, mastoidectomy for the PSA can be considered time-consuming and to carry a higher risk of complications due to the anatomical complexity of the region. The authors established a method of minimized mastoidectomy focused on exposing Trautmann\u2019s triangle as the corridor for the PSA while maximizing procedural simplicity and safety and maintaining a sufficient operative view. The authors present their method of minimized mastoidectomy in a cadaver dissection and operative cases, showing potential as a useful option for the PSA.<\/jats:p>","DOI":"10.3171\/2020.1.jns193179","type":"journal-article","created":{"date-parts":[[2020,3,27]],"date-time":"2020-03-27T20:48:31Z","timestamp":1585342111000},"page":"843-847","source":"Crossref","is-referenced-by-count":4,"title":["Trautmann-focused mastoidectomy for a simple, safe presigmoid approach: technical note"],"prefix":"10.3171","volume":"134","author":[{"given":"Kuniaki","family":"Tanahashi","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kenji","family":"Uda","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yoshio","family":"Araki","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kazuhito","family":"Takeuchi","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jungsu","family":"Choo","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lushun","family":"Chalise","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kazuya","family":"Motomura","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Fumiharu","family":"Ohka","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Toshihiko","family":"Wakabayashi","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Atsushi","family":"Natsume","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1754","reference":[{"issue":"4","key":"b1","series-title":"J Neurosurg","doi-asserted-by":"publisher","first-page":"544","DOI":"10.3171\/jns.1997.87.4.0544","article-title":"Cranial base approaches to posterior circulation aneurysms","volume":"87","author":"Day JD","year":"1997","unstructured":"Day JD, Fukushima T, Giannotta SL.
