The scutum-CP and scutum\u2013promontorium distances were measured. Facial canal dehiscence (FCD) in the tympanic segment and mastoid pneumatization were also evaluated.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>The distances between scutum-CP and scutum\u2013promontorium were not different between males and females and between right and left sides. Facial canal dehiscence in the tympanic segment was detected: 5.6% (right) and 7.8% (left) in males and 5.5% (right) and 10.0% (left) in females. Grade 4 (100%) pneumatization was detected mainly in 55.6% to 57.8% of the patients in both genders. Grade 0 (0%) pneumatization (sclerosis) was detected in 22.2% to 28.2% of both males and females. In more pneumatized mastoids, the scutum-CP and scutum\u2013promontorium distances increased. In sclerotic mastoids, the scutum-CP and scutum\u2013promontorium distances decreased. Facial canal dehiscence rates were not related to the mastoid pneumatization levels.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion:<\/jats:title>\n                    <jats:p>Cochleariform process is an important landmark to localize the tympanic segment of the facial canal. In sclerosed mastoids, scutum-CP and scutum\u2013promontorium distances decreased. There was no relationship between FCD rates and mastoid pneumatization levels. It may be due to the development of FCD that occurs during the intrauterine period. In endoscopic and classic ear surgeries, mastoid pneumatization must be evaluated preoperatively to avoid facial nerve injuries.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1177\/0145561319879528","type":"journal-article","created":{"date-parts":[[2019,10,4]],"date-time":"2019-10-04T02:03:02Z","timestamp":1570154582000},"page":"497-503","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":5,"title":["Can MDCT Scan of the Temporal Bone Looking at Pneumatization Predict Surgical Vulnerability of the Facial Nerve?"],"prefix":"10.1177","volume":"100","author":[{"given":"Mikail","family":"Inal","sequence":"first","affiliation":[{"name":"Radiology Department, Faculty of Medicine, K\u0131r\u0131kkale University, K\u0131r\u0131kkale, Turkey"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3602-9289","authenticated-orcid":false,"given":"Nuray Bayar","family":"Muluk","sequence":"additional","affiliation":[{"name":"ENT Department, Faculty of Medicine, K\u0131r\u0131kkale University, K\u0131r\u0131kkale, Turkey"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mehmet Hamdi","family":"\u015eahan","sequence":"additional","affiliation":[{"name":"Radiology Department, Faculty of Medicine, Gaziantep University, Gaziantep, Turkey"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ne\u015fe","family":"Asal","sequence":"additional","affiliation":[{"name":"Radiology Department, Faculty of Medicine, K\u0131r\u0131kkale University, K\u0131r\u0131kkale, Turkey"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"G\u00f6k\u00e7e","family":"\u015eim\u015fek","sequence":"additional","affiliation":[{"name":"ENT Department, Faculty of Medicine, K\u0131r\u0131kkale University, K\u0131r\u0131kkale, Turkey"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Osman K\u00fcr\u015fat","family":"Ar\u0131kan","sequence":"additional","affiliation":[{"name":"ENT Clinics, VM Mersin Medical Park Hospital, Mersin, Turkey"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2019,10,3]]},"reference":[{"key":"bibr1-0145561319879528","doi-asserted-by":"publisher","DOI":"10.1016\/j.anl.2007.09.012"},{"key":"bibr2-0145561319879528","doi-asserted-by":"publisher","DOI":"10.1177\/000348941112000408"},{"key":"bibr3-0145561319879528","doi-asserted-by":"publisher","DOI":"10.1002\/lary.21819"},{"issue":"2","key":"bibr4-0145561319879528","first-page":"243","volume":"51","author":"M\u0103ru N","year":"2010","journal-title":"Rom J Morphol Embryol"},{"key":"bibr5-0145561319879528","doi-asserted-by":"publisher","DOI":"10.1258\/00222150260293600"},{"key":"bibr6-0145561319879528","doi-asserted-by":"publisher","DOI":"10.2214\/ajr.139.4.739"},{"key":"bibr7-0145561319879528","doi-asserted-by":"publisher","DOI":"10.3109\/00016480902922752"},{"key":"bibr8-0145561319879528","doi-asserted-by":"publisher","DOI":"10.1097\/SCS.0000000000002129"},{"key":"bibr9-0145561319879528","doi-asserted-by":"publisher","DOI":"10.1001\/archotol.1981.00790370003001"},{"key":"bibr10-0145561319879528","first-page":"105","volume-title":"Interatemporal Facial Nerve Paralysis, Pathophysiology and Treatment","author":"Yanagihara N","year":"1985"},{"key":"bibr11-0145561319879528","doi-asserted-by":"publisher","DOI":"10.3109\/00016489.2013.816443"},{"issue":"4","key":"bibr12-0145561319879528","first-page":"1","volume":"90","author":"Ge XX","year":"1982","journal-title":"Ann Otol Rhinol Laryngol Suppl"},{"key":"bibr13-0145561319879528","doi-asserted-by":"publisher","DOI":"10.1288\/00005537-199309000-00018"},{"issue":"4","key":"bibr14-0145561319879528","first-page":"395","volume":"77","author":"Ezzat WE","year":"2009","journal-title":"Med J Cairo Univ"},{"key":"bibr15-0145561319879528","doi-asserted-by":"publisher","DOI":"10.1177\/000348949610500609"},{"key":"bibr16-0145561319879528","doi-asserted-by":"publisher","DOI":"10.1097\/00129492-200109000-00007"},{"key":"bibr17-0145561319879528","doi-asserted-by":"publisher","DOI":"10.1097\/00129492-200103000-00002"},{"key":"bibr18-0145561319879528","doi-asserted-by":"publisher","DOI":"10.1097\/01.mao.0000247824.90774.22"},{"key":"bibr19-0145561319879528","doi-asserted-by":"publisher","DOI":"10.1016\/j.otohns.2004.02.054"},{"key":"bibr20-0145561319879528","doi-asserted-by":"publisher","DOI":"10.1007\/s12070-011-0159-0"},{"key":"bibr21-0145561319879528","doi-asserted-by":"publisher","DOI":"10.1148\/radiology.199.3.8637972"},{"key":"bibr22-0145561319879528","doi-asserted-by":"publisher","DOI":"10.32412\/pjohns.v23i1.775"},{"key":"bibr23-0145561319879528","doi-asserted-by":"publisher","DOI":"10.1007\/s00405-013-2479-z"}],"container-title":["Ear, Nose &amp;
