Temporary tinnitus can be caused by blockages in the middle ear, including:

Occasionally these items can damage the eardrum, causing permanent tinnitus.

Tinnitus can also be caused by medications, including certain:

  • Aspirin
  • Antibiotics
  • Diuretics
  • Quinine drugs
  • Chemotherapy drugs

Diagnosing tinnitus

The type of sound associated with your tinnitus can help your physician determine its cause. Another technique is to examine how various movements impact the sound you hear.

Diagnostic tests include:

  • Hearing test: A traditional hearing test is used to determine if you are experiencing hearing loss.
  • Computed tomography (CT) scan: This test combines X-ray and computer technology to produce detailed cross-sectional images.
  • Magnetic resonance imaging (MRI) scan: This test creates detailed images using a large magnet, a computer and radiofrequencies. Unlike computed tomography (CT or CAT) scans or X-rays, MRI does not use radiation.
