Overview
Otalgia is caused by pathology either in the primary source which involves the ear itself or a distance source which causes referred pain to the ear. Computed tomography (CT) scan is of great help in evaluating both the possible causes. CT with contrast is indicated when the goal is to determine the extent of the disease. It is also used in evaluating temporal bone trauma.
Computed tomography scan
CT scan can be used to assess the complications of:
- Otitis media
- Cholesteatoma
- Otitis externa
- Mastoiditis
- Ear Trauma
- Acoustic neuroma [1]
- Sinusitis
- Upper aerodigestive tract tumors - to determine the extent, spread and involvement of organs.
- Cervical adenopathy
- Eagle's syndrome (elongation of styloid process)[2]
Involvement and erosion of the temporal bones can be well assessed using Computed tomography scan. [3]
