Diagnosis
The doctor will ask about your symptoms and medical history, and perform a physical exam. Tests may include:
- Weber test—a tuning fork is sounded and placed on your forehead or teeth. This can help distinguish conductive from sensorineural hearing loss.
- Rinne test—a tuning fork is sounded and placed in front and then behind of the ear. This can help distinguish conductive from sensorineural hearing loss.
- Audiometric tests—these involve listening to tones in a soundproof room, and reporting whether or not you hear the tones.
- Tympanometry—this test measures the pressure in the middle ear and examines the middle ear's response to pressure waves.
- CT or MRI scan of the head —a type of imaging study that uses a computer to make pictures of the inside of the head. This may be done to check for a tumor or bone injury.
- Brain stem auditory evoked responses—in this test, electrodes are attached to the scalp and used to measure the electrical response of the brain to sound.
- Electrocochleography—this tests the cochlea and the auditory nerve.
