Early attempts to expose this region consisted primarily of an extended suboccipital craniectomy, with opening of the tentorium and ligation of the sigmoid sinus for additional exposure. During the 1960s, technological innovations including the surgical microscope and the pneumatic drill allowed surgeons to gain additional exposure by removing more bone from the base of the skull. This let surgeons define combined infra- and supratentorial approaches, which rely less on brain retraction to resect these difficult tumors successfully. These approaches rely on a combined posterior mastoid approach with an anterior petrosectomy. The evolution of this approach is discussed in this paper.<\/jats:p>","DOI":"10.3171\/2012.6.focus12141","type":"journal-article","created":{"date-parts":[[2012,8,1]],"date-time":"2012-08-01T09:10:27Z","timestamp":1343812227000},"page":"E8","source":"Crossref","is-referenced-by-count":23,"title":["The history of the combined supra- and infratentorial approach to the petroclival region"],"prefix":"10.3171","volume":"33","author":[{"given":"Peter M.","family":"Grossi","sequence":"first","affiliation":[{"name":"Duke Raleigh Hospital and"},{"name":"Department of Surgery, Division of Neurosurgery, Duke University, Durham, North Carolina"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yoichi","family":"Nonaka","sequence":"additional","affiliation":[{"name":"Carolina Neurosciences Institute, Raleigh; and"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kentaro","family":"Watanabe","sequence":"additional","affiliation":[{"name":"Carolina Neurosciences Institute, Raleigh; and"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Takanori","family":"Fukushima","sequence":"additional","affiliation":[{"name":"Duke Raleigh Hospital and"},{"name":"Department of Surgery, Division of Neurosurgery, Duke University, Durham, North Carolina"},{"name":"Carolina Neurosciences Institute, Raleigh; and"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1754","reference":[{"key":"b1-0330008","series-title":"Zentralbl Neurochir","first-page":"1","article-title":"Concerning the technique of operation for acoustic neurinoma","volume":"4","author":"Bailey","year":"1939"},{"key":"b2-0330008","series-title":"Klin Wochenschr","first-page":"1033","article-title":"Zur Operation der Tumoren des Kleinhirn-Br\u00fcckenwinkels","volume":"42","author":"Borchardt","year":"1905"},{"key":"b3-0330008","series-title":"Surg Clin North Am","first-page":"1427","article-title":"The management of tumors of the posterior fossa by a transtentorial approach","volume":"10","author":"Fay","year":"1930"},{"key":"b4-0330008","series-title":"Ann Surg","first-page":"293","article-title":"I.
