The objective of our study was to complete a review of the literature to compare the EN and OP approaches on multiple levels, notably on safety and effectiveness. Ovid MEDLINE and Embase were used to perform a thorough literature review of all cases of PACG treated by either EN or OP dating from January 1948 to August 2017. In total, 49 articles were selected including 23 for EN (n=76) and 26 for OP (n=210). Differences were found in the incidence of preoperative hearing loss (HL) (EN 18.4%, OP 57.3%; p<\/jats:p>","DOI":"10.5152\/iao.2019.5859","type":"journal-article","created":{"date-parts":[[2019,7,9]],"date-time":"2019-07-09T07:52:27Z","timestamp":1562658747000},"page":"193-199","source":"Crossref","is-referenced-by-count":14,"title":["Cholesterol Granulomas: A Comparative Meta-Analysis of Endonasal Endoscopic versus Open Approaches to the Petrous Apex"],"prefix":"10.65717","volume":"15","author":[{"given":"Paul","family":"Tabet","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Nadim","family":"Saydy","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Issam","family":"Saliba","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"55248","published-online":{"date-parts":[[2019,9,3]]},"container-title":["The Journal of International Advanced Otology"],"original-title":[],"link":[{"URL":"https:\/\/www.advancedotology.org\/index.php\/pub\/article\/download\/1120\/1118","content-type":"unspecified","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/www.advancedotology.org\/index.php\/pub\/article\/download\/1200\/1198","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/www.advancedotology.org\/index.php\/pub\/article\/download\/1200\/1198","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,1,22]],"date-time":"2026-01-22T10:51:41Z","timestamp":1769079101000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.advancedotology.org\/index.php\/pub\/article\/view\/1200"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2019,9,3]]},"references-count":0,"journal-issue":{"issue":"2","published-online":{"date-parts":[[2019,9,3]]}},"URL":"https:\/\/doi.org\/10.5152\/iao.2019.5859","relation":{},"ISSN":["2148-3817"],"issn-type":[{"value":"2148-3817","type":"electronic"}],"subject":[],"published":{"date-parts":[[2019,9,3]]}}}
