Sensorineural hearing loss is more common in patients with a transverse fracture than those with a longitudinal fracture. Hearing loss is most commonly secondary to injury to the labyrinthine structures, but could also occur from transection of the cochlear nerve, or stapes footplate injury. A transverse fracture is more likely to injure the facial nerve (cranial nerve VII) than a longitudinal fracture.\u003c/p\u003e\u003cp\u003eOn the other hand, ossicles and tympanic membrane are more commonly injured in a longitudinal fracture.\u003c/p\u003e","id":2667,"imageUrl":null,"imageAttribution":null,"imageAttributionCaseInfo":null,"firstQuestionPath":"/questions/2667","nextQuestionPath":"/articles/transverse-temporal-bone-fractures/questions/946","relatedArticles":[],"alsoUsedIn":[{"id":1719,"kind":"Course","title":"2023 Virtual Conference Private Use - page 1719","link":"https://radiopaedia.org/courses/2023-virtual-conference-private-use/pages/1719"},{"id":365,"kind":"LiveSchedule","title":"365","link":"https://radiopaedia.org/admin/live_schedules/365"},{"id":270,"kind":"LiveSchedule","title":"270","link":"https://radiopaedia.org/admin/live_schedules/270"},{"id":267,"kind":"LiveSchedule","title":"267","link":"https://radiopaedia.org/admin/live_schedules/267"},{"id":1472,"kind":"Course","title":"2023 Virtual Conference Private Use - page 1472","link":"https://radiopaedia.org/courses/2023-virtual-conference-private-use/pages/1472"},{"id":1472,"kind":"Course","title":"Head \u0026 Neck Lectures - page 1472","link":"https://radiopaedia.org/courses/head-neck-lectures/pages/1472"}],"stem":"\u003cp\u003eA 55-year-old male presents to the emergency department after being struck by a tree.
