The Physical Examination
The first step in diagnosing ear barotrauma is a thorough physical examination. Your doctor will use an otoscope, a special instrument to look inside your ear. They'll check for signs like a red or swollen eardrum, fluid behind the eardrum, or in severe cases, a perforated eardrum. This visual inspection can often confirm the diagnosis.
Hearing Tests
If you're experiencing hearing loss, your doctor may perform simple hearing tests. The Rinne and Weber tests use a tuning fork to assess your hearing. These tests can help determine if your hearing loss is conductive (in the middle ear) or sensorineural (in the inner ear). More comprehensive audiometry tests might be used for a detailed evaluation of your hearing.
Tympanometry
Tympanometry is a test that measures how well your eardrum moves. It can detect fluid in the middle ear, eardrum perforations, or Eustachian tube dysfunction. During the test, a small device is placed in your ear canal, and air pressure is changed to see how your eardrum responds.
Imaging Studies
In severe cases or when complications are suspected, your doctor might order imaging studies. A CT scan can provide detailed images of your middle and inner ear structures. This is particularly useful if there's concern about inner ear damage or to rule out other conditions.
