Which of the following can cause vertigo due to inner ear abnormalities?

The choice regarding the otic capsule violating temporal bone fractures is correct in the context of vertigo due to inner ear abnormalities. The otic capsule houses important structures of the inner ear, including those responsible for balance and spatial orientation, such as the cochlea and the vestibular apparatus. When a temporal bone fracture occurs and violates the otic capsule, it can disrupt the delicate structures within the inner ear, potentially leading to vestibular dysfunction. This dysfunction manifests as vertigo, characterized by the sensation of spinning or losing balance.

Other options do not directly relate to inner ear abnormalities linked to vertigo. Inflammation of the auditory canal primarily affects the outer ear and is typically associated with ear pain rather than balance issues. Allergies to certain medications may result in various side effects, but they are not a direct cause of inner ear abnormalities leading to vertigo. Declining hearing age, although related to changes in auditory function, does not directly imply the inner ear abnormalities that would result in vertigo.
