Expanding bone removal of the petrous apex around the petrous internal carotid artery (ICA), underneath the trigeminal ganglion\/mandibular nerve, and into the lateral component of the clivus can significantly expand the limits of this approach beyond the inferior petrosal sinus and allows for exposure of the midline structures, aspects of the contralateral inferior clival region, and, when high riding, the vertebrobasilar junction. To date, no descriptive techniques for drilling into the lateral clivus in this approach have been published. The authors provide a detailed stepwise description of their complete anterior petrosectomy, in use at their institution, that involves skeletonization of the posteromedial petrous ICA, gentle elevation of the trigeminal ganglion\/mandibular nerve, removal of the infratrigeminal petrous apex, and two techniques for drilling into the lateral clivus along the petroclival fissure. These techniques provide a direct and unobstructed corridor to the midpetroclival region and ventral brainstem with greater maneuverability and enhanced control of the midline structures, which is especially useful for resection of petroclival meningiomas, chondrosarcomas, and giant vascular lesions of the mid- and upper basilar artery and its proximal branches.<\/jats:p>","DOI":"10.3171\/2023.11.jns231303","type":"journal-article","created":{"date-parts":[[2024,1,20]],"date-time":"2024-01-20T01:19:13Z","timestamp":1705713553000},"page":"195-203","source":"Crossref","is-referenced-by-count":6,"title":["The complete anterior petrosectomy: an expanded extended-middle fossa approach with removal of the infratrigeminal petrous apex and drilling of the lateral clivus"],"prefix":"10.3171","volume":"141","author":[{"given":"Collin","family":"Liu","sequence":"first","affiliation":[{"name":"Weill Cornell Medicine, Neurological Surgery, New York, New York;"},{"name":"Deptartment of Neurosurgery, University of Nebraska Medical Center, Omaha, Nebraska;"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Alexander I.","family":"Evins","sequence":"additional","affiliation":[{"name":"Weill Cornell Medicine, Neurological Surgery, New York, New York;"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Travis J.","family":"Atchley","sequence":"additional","affiliation":[{"name":"Weill Cornell Medicine, Neurological Surgery, New York, New York;"},{"name":"Department of Neurosurgery, University of Alabama at Birmingham Health System, Birmingham, Alabama; and"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Daniel L.","family":"Surdell","sequence":"additional","affiliation":[{"name":"Deptartment of Neurosurgery, University of Nebraska Medical Center, Omaha, Nebraska;"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"William E.","family":"Thorell","sequence":"additional","affiliation":[{"name":"Deptartment of Neurosurgery, University of Nebraska Medical Center, Omaha, Nebraska;"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Motonobu","family":"Nonaka","sequence":"additional","affiliation":[{"name":"Weill Cornell Medicine, Neurological Surgery, New York, New York;"},{"name":"Department of Neurosurgery, Kochi University Hospital, Kochi, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Philip E.","family":"Stieg","sequence":"additional","affiliation":[{"name":"Weill Cornell Medicine, Neurological Surgery, New York, New York;"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Antonio","family":"Bernardo","sequence":"additional","affiliation":[{"name":"Weill Cornell Medicine, Neurological Surgery, New York, New York;"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1754","reference":[{"key":"b1","series-title":"Laryngoscope","first-page":"1363","article-title":"Surgical exposure of the internal auditory canal and its contents through the middle, cranial fossa","volume":"71","author":"House WF","year":"1961","unstructured":"House WF.
