Traumatic and nontraumatic causes have been demonstrated. This study was performed to determine the prevalence and outcomes of bilateral traumatic FNP.Subjects and Methods: We retrospectively reviewed temporal bone fracture (TBF) cases from 2010 to 2019. Number of patients and each patient\u2019s characteristics were obtained using the hospital coding system.Results: A total of 336 TBF cases were identified, among which 316 (94%) were unilateral and 20 (6%) were bilateral. Among these 20 cases, five (25%) developed bilateral FNP, all resulting from bilateral TBF and accounting for 1.5% of all TBF cases. Four of these five patients experienced delayedonset bilateral FNP, and one patient experienced immediate onset on one side and delayed onset on the other. All five patients developed incomplete FNP, with the most severe case scored House\u2013Brackmann grade IV. Longitudinal TBF was the cause in all but one case, which resulted from mixed fractures on one side. All five patients were treated conservatively with oral steroids and physiotherapy.Conclusions: Although bilateral traumatic FNP is rare, it should be suspected in all cases of bilateral TBF, and close follow-up is required to achieve rapid diagnosis and enhance management. Because bilateral TBF strongly tends to be longitudinal, incomplete FNP is typical.<\/jats:p>","DOI":"10.7874\/jao.2025.00150","type":"journal-article","created":{"date-parts":[[2025,7,20]],"date-time":"2025-07-20T23:43:26Z","timestamp":1753055006000},"page":"214-218","update-policy":"https:\/\/doi.org\/10.7874\/crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Traumatic Bilateral Facial Nerve Palsy: A 10-Year Retrospective Study"],"prefix":"10.7874","volume":"29","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-4802-2260","authenticated-orcid":true,"given":"Vshakri","family":"Ehdam","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5056-6446","authenticated-orcid":true,"given":"Mohd Khairi Md","family":"Daud","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"4621","reference":[{"key":"ref1","doi-asserted-by":"publisher","DOI":"10.1080\/0269905031000149489"},{"key":"ref2","first-page":"201","volume-title":"Bilateral simultaneous Bell\u2019s palsy: a clinical note","author":"Daud","year":"2012"},{"key":"ref3","doi-asserted-by":"publisher","DOI":"10.1007\/s12070-018-1371-y"},{"key":"ref4","doi-asserted-by":"publisher","DOI":"10.1097\/scs.0000000000004569"},{"key":"ref5","doi-asserted-by":"publisher","DOI":"10.1016\/j.otohns.2005.01.027"},{"key":"ref6","doi-asserted-by":"publisher","DOI":"10.7860\/jcdr\/2015\/11255.5841"},{"key":"ref7","first-page":"306950","volume-title":"Bilateral facial paralysis caused by bilateral temporal bone fracture: a case report and a literature review","author":"Eli\u00e7ora","year":"2015"},{"key":"ref8","doi-asserted-by":"publisher","DOI":"10.1067\/mhn.2001.116182"},{"key":"ref9","first-page":"239","volume-title":"Bilateral post-traumatic facial palsy: a case report and literature review","author":"Parrino","year":"2022"},{"key":"ref10","doi-asserted-by":"publisher","DOI":"10.1016\/s0973-0508(05)80008-5"},{"key":"ref11","doi-asserted-by":"publisher","DOI":"10.1016\/s0030-6665(20)32849-8"},{"key":"ref12","volume-title":"","author":"Diamond","year":"1979"},{"key":"ref13","doi-asserted-by":"publisher","DOI":"10.1288\/00005537-198408000-00005"},{"key":"ref14","first-page":"262","volume-title":"Traumatic intratemporal facial nerve injury: management rationale for preservation of function","author":"Coker","year":"1987"},{"key":"ref15","doi-asserted-by":"publisher","DOI":"10.13004\/jknts.2006.2.2.136"},{"key":"ref16","doi-asserted-by":"publisher","DOI":"10.18203\/issn.2454-5929.ijohns20202209"},{"key":"ref17","doi-asserted-by":"publisher","DOI":"10.1097\/00129492-200200001-00155"},{"key":"ref18","doi-asserted-by":"publisher","DOI":"10.1097\/ta.0b013e318236b21f"},{"key":"ref19","doi-asserted-by":"publisher","DOI":"10.1097\/scs.0000000000004641"}],"container-title":["Journal of Audiology and Otology"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/ejao.org\/upload\/pdf\/jao-2025-00150.pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/ejao.org\/journal\/view.php?doi=10.7874\/jao.2025.00150","content-type":"unspecified","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/ejao.org\/upload\/pdf\/jao-2025-00150.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,7,28]],"date-time":"2025-07-28T02:16:18Z","timestamp":1753668978000},"score":1,"resource":{"primary":{"URL":"http:\/\/ejao.org\/journal\/view.php?doi=10.7874\/jao.2025.00150"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2025,7,20]]},"references-count":19,"journal-issue":{"issue":"3","published-print":{"date-parts":[[2025,7]]}},"URL":"https:\/\/doi.org\/10.7874\/jao.2025.00150","relation":{},"ISSN":["2384-1621","2384-1710"],"issn-type":[{"value":"2384-1621","type":"print"},{"value":"2384-1710","type":"electronic"}],"subject":[],"published":{"date-parts":[[2025,7,20]]},"assertion":[{"value":"2025-03-06","order":0,"name":"received","label":"Received","group":{"name":"publication_history","label":"Publication History"}},{"value":"2025-04-15","order":1,"name":"accepted","label":"Accepted","group":{"name":"publication_history","label":"Publication History"}},{"value":"2025-07-18","order":2,"name":"published","label":"Published online","group":{"name":"publication_history","label":"Publication History"}},{"value":"2025-07-20","order":3,"name":"published","label":"Print publication","group":{"name":"publication_history","label":"Publication History"}}]}}
