    Signs and tests

    A doctor will look into your ear for signs of an outer ear infection (otitis externa). The head around and behind the ear may be tender to touch. A nervous system (neurological) examination may show that the cranial nerves are affected.

    If there is any drainage, the doctor may send it to the lab for a culture. The purpose of the culture is to look for bacteria or fungi, usually the bacteria Pseudomonas.

    To look for signs of a bone infection next to the ear canal, the following tests may be performed:

    • CT scan of the head
    • MRI scan of the head
    • Radionuclide scan
