Medical Specialties

At the Center for Neurosciences, we work together across specialties to provide the best, most comprehensive approach to treatment.

Temporal Bone Trauma

The temporal bones are located on the sides of the head, just above/behind the outer ear and at the temple. It forms our lateral skull base, on which the brain rests. Temporal bone trauma can be blunt or penetrating. Blunt trauma involves a closed injury to the head, such as a motor vehicle accident or falls. Penetrating trauma involves actual puncture to the temporal bone (e.g., a gunshot wound). The level of trauma experienced varies greatly depending on the extent of the injury. Temporal bone trauma may cause problems with hearing, balance or facial nerve function. Hearing loss may be conductive or sensorineural depending on the location of the fracture.

Temporal bone trauma is typically experienced with a number of other injuries, some life-threatening. When determining a course of treatment, prioritizing the severity of other injuries is of primary importance. Once the patient is stabilized, the patient may be referred to Dr. Jacob for evaluation and treatment of otological and/or facial nerve symptoms. A hearing test and CT/MRI scans help determine the extent of injury. If there is evidence of cerebrospinal fluid (CSF) leakage, perilymph fistula, ossicular chain discontinuity (middle ear bones are not aligned properly), tympanic membrane perforation (insert link) or cholesteatoma, surgery may be indicated. Dizziness is commonly experienced following temporal bone trauma and may be due to inner ear concussion or fracture of the otic capsule (inner ear). Typically, no treatment is required, as the brain usually learns to compensate over time. In some patients, however, Benign Paroxysmal Positional Vertigo or Meniere’s syndrome may occur.
