Many authors have attempted to identify prognostic factors for successful hearing preservation, and many have suggested alternative procedures for preserving serviceable hearing. Few have mentioned hearing improvement with skull base surgical procedures. In this article we present the hearing results of 25 surgical procedures for primary petrous apex lesions. These Include 13 cholesterol granulomas, 5 cholesteatomas, 4\u00a0mucoceles, and 3 eosinophilic granulomas. Surgical approaches included 14 transmastoid\/infralabyrinthine, 6 transphenoid, 3 suboccipital, and 2 transmastoid\/translabyrinthine. Hearing was maintained In 14 patients (56%), Improved in 9 patients (36%), and worse in 1 patient with nonserviceable hearing before surgery (4%); 1 patient had profound hearing loss before surgery (4%). Results of this review should have significant implications on the choice of surgical approach for petrous apex lesions. Additionally, the standard method of determining salvageable hearing for most skull base procedures may not apply for this specific group of lesions. Implications for future treatment plans will be discussed in detail.<\/jats:p>","DOI":"10.1177\/01945998941113p114","type":"journal-article","created":{"date-parts":[[2015,11,25]],"date-time":"2015-11-25T06:54:07Z","timestamp":1448434447000},"page":"250-257","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Hearing Results in Surgery for Primary Petrous Apex Lesions"],"prefix":"10.1002","volume":"111","author":[{"given":"Gerard J.","family":"Gianoli","sequence":"first","affiliation":[{"name":"Department of Otolaryngology\u2010Head and Neck Surgery Tulane University Medical Center New Orleans Louisiana"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ronald G.","family":"Amedee","sequence":"additional","affiliation":[{"name":"Department of Otolaryngology\u2010Head and Neck Surgery Tulane University Medical Center New Orleans Louisiana"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2016,11,8]]},"reference":[{"key":"e_1_2_1_2_1","doi-asserted-by":"publisher","DOI":"10.1055\/s-2008-1058982"},{"key":"e_1_2_1_3_1","first-page":"13","article-title":"Lesions of the petrous apex","volume":"142","author":"Gianoli GJ","year":"1990","journal-title":"J La State Med Soc"},{"key":"e_1_2_1_4_1","doi-asserted-by":"publisher","DOI":"10.1177\/0003489475084S1801"},{"key":"e_1_2_1_5_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0030-6665(20)30965-8"},{"key":"e_1_2_1_6_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0030-6665(20)31943-5"},{"key":"e_1_2_1_7_1","first-page":"561","article-title":"Radiographic differential diagnosis of petrous apex lesions","volume":"13","author":"Jackler RK","year":"1992","journal-title":"Am J Otol"},{"key":"e_1_2_1_8_1","doi-asserted-by":"publisher","DOI":"10.1288\/00005537-198506000-00005"},{"key":"e_1_2_1_9_1","first-page":"203","article-title":"Primary mucocele of the petrous apex: MR appearance","volume":"13","author":"Larson TL","year":"1992","journal-title":"AJNR Am J Neuroradiol"},{"key":"e_1_2_1_10_1","first-page":"121","article-title":"CT and MRI findings in patients with chordomas of the petrous apex","volume":"11","author":"Brown RV","year":"1990","journal-title":"AJNR Am J Neuroradiol"},{"key":"e_1_2_1_11_1","doi-asserted-by":"publisher","DOI":"10.1177\/000348948809700605"},{"key":"e_1_2_1_12_1","doi-asserted-by":"publisher","DOI":"10.1288\/00005537-198909000-00003"},{"key":"e_1_2_1_13_1","doi-asserted-by":"publisher","DOI":"10.1001\/archotol.1989.01860330111030"},{"key":"e_1_2_1_14_1","doi-asserted-by":"publisher","DOI":"10.1017\/S0022215100097024"},{"key":"e_1_2_1_15_1","first-page":"48","article-title":"Cholesterol granuloma of the petrous apex","volume":"8","author":"Amedee RG","year":"1987","journal-title":"Am J Otol"}],"container-title":["Otolaryngology\u2013Head and Neck Surgery"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1177\/01945998941113P114","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/aao-hnsfjournals.onlinelibrary.wiley.com\/doi\/pdf\/10.1177\/01945998941113P114","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,10,20]],"date-time":"2025-10-20T12:11:34Z","timestamp":1760962294000},"score":1,"resource":{"primary":{"URL":"https:\/\/aao-hnsfjournals.onlinelibrary.wiley.com\/doi\/10.1177\/01945998941113P114"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[1994,9]]},"references-count":14,"journal-issue":{"issue":"3P1","published-print":{"date-parts":[[1994,9]]}},"alternative-id":["10.1177\/01945998941113P114"],"URL":"https:\/\/doi.org\/10.1177\/01945998941113p114","archive":["Portico"],"relation":{},"ISSN":["0194-5998","1097-6817"],"issn-type":[{"value":"0194-5998","type":"print"},{"value":"1097-6817","type":"electronic"}],"subject":[],"published":{"date-parts":[[1994,9]]},"assertion":[{"value":"1993-10-03","order":0,"name":"received","label":"Received","group":{"name":"publication_history","label":"Publication History"}},{"value":"1994-01-31","order":2,"name":"accepted","label":"Accepted","group":{"name":"publication_history","label":"Publication History"}},{"value":"2016-11-08","order":3,"name":"published","label":"Published","group":{"name":"publication_history","label":"Publication History"}}]}}
