Patient data were collected from initial presentation and subsequent follow\u2010up clinic visits.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Thirty\u2010nine percent of temporal bone fractures and 3.3% of mandible trauma involved the EAC. In particular, 10% of condylar or subcondylar trauma included an EAC fracture (<jats:italic>P<\/jats:italic>\u2009=\u20090.0006). One patient sustained bilateral EAC fractures despite an isolated, unilateral condylar fracture. The most common presenting sign was blood in the external auditory canal. Two patients underwent exam under anesthesia and removal of debris and stenting as treatment, whereas 42% of the patients were placed on otic drops and 5% received packing or a stent. Follow\u2010up data were only available for 16% of the patients. Hearing loss from otic capsule involvement or ossicular chain disruption were follow\u2010up complaints, and one patient had persistent canal stenosis.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>External auditory canal trauma is present in a significant proportion of mandibular and temporal bone trauma, including both condylar and noncondylar fractures with a higher incidence of condylar fractures. One case was seen with bilateral EAC fractures despite a unilateral mandibular fracture. Complications of these fractures can include hearing loss and canal stenosis; however, additional outpatient follow\u2010up is needed to further elucidate long\u2010term complications and shape treatment recommendations.<\/jats:p><\/jats:sec><jats:sec><jats:title>Level of Evidence<\/jats:title><jats:p>4. <jats:italic>Laryngoscope<\/jats:italic>, 125:1579\u20131582, 2015<\/jats:p><\/jats:sec>","DOI":"10.1002\/lary.25246","type":"journal-article","created":{"date-parts":[[2015,3,17]],"date-time":"2015-03-17T00:48:12Z","timestamp":1426553292000},"page":"1579-1582","source":"Crossref","is-referenced-by-count":26,"title":["Trauma patterns, symptoms, and complications associated with external auditory canal fractures"],"prefix":"10.1002","volume":"125","author":[{"given":"Daniela M.","family":"Burchhardt","sequence":"first","affiliation":[{"name":"Department of Otolaryngology\u2013Head and Neck Surgery Wayne State University School of Medicine Detroit Michigan U.S.A."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"John","family":"David","sequence":"additional","affiliation":[{"name":"Department of Oncology, Karmanos Cancer Institute Wayne State University School of Medicine Detroit Michigan U.S.A."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Robert","family":"Eckert","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Natasha L.","family":"Robinette","sequence":"additional","affiliation":[{"name":"Department of Oncology, Karmanos Cancer Institute Wayne State University School of Medicine Detroit Michigan U.S.A."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Michael A.","family":"Carron","sequence":"additional","affiliation":[{"name":"Department of Otolaryngology\u2013Head and Neck Surgery Wayne State University School of Medicine Detroit Michigan U.S.A."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Giancarlo F.","family":"Zuliani","sequence":"additional","affiliation":[{"name":"Department of Otolaryngology\u2013Head and Neck Surgery Wayne State University School of Medicine Detroit Michigan U.S.A."}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2015,3,16]]},"reference":[{"key":"e_1_2_6_2_1","first-page":"271","article-title":"[Auditory canal hemorrhage as a symptom of mandibular trauma].
