What is this test?
CT (Computed Tomography) imaging of the temporal bone is a specialized scan that provides high-resolution cross-sectional images of the bones surrounding the ear, including the middle and inner ear structures. This test uses X-rays to capture detailed views of the complex anatomy of the temporal bones, which house critical components responsible for hearing and balance.
What is it used for?

• Diagnosing chronic or acute ear infections that may involve bone erosion or complications
• Detecting fractures of the temporal bone following trauma to the head or ear region
• Identifying tumors or cysts in the temporal bone or adjacent areas
• Evaluating causes of hearing loss, tinnitus (ringing in the ears), or dizziness related to inner ear disorders
• Assessing structural abnormalities such as otosclerosis or congenital malformations
• Planning surgical interventions involving the ear or temporal bone

Who should get this test?

• Patients experiencing persistent ear pain, hearing loss, or recurrent infections
• Individuals with a history of head trauma affecting the ear or temporal bone region
• Patients with symptoms of vertigo or balance disturbances suspected to originate from the inner ear
• Those with suspected temporal bone tumors or abnormal growths
• Candidates for ear surgery requiring detailed anatomical imaging

Preparation Required:

• No special preparation or fasting is required prior to the scan
• Patients should inform the technician about any previous ear surgeries or implants
• Removal of any metallic objects near the head, such as jewelry or hearing aids, is necessary before scanning

How is the procedure performed?
The CT temporal bone scan is a quick procedure, typically lasting 5 to 10 minutes. The patient lies on a motorized table that slides into the CT scanner. Multiple thin-slice X-ray images are taken in rapid succession to create detailed, 3D-like views of the temporal bones. The scan is painless and non-invasive, with the patient needing to remain still for optimal image quality.
Risks & Safety:
This procedure involves exposure to ionizing radiation, which is generally low but should be considered, especially in younger patients or those requiring repeated scans. The risk is outweighed by the diagnostic benefits in most cases. There are no contrast dyes used for this scan, so allergic reactions are not a concern.
Results:
A radiologist analyzes the images to identify abnormalities in the temporal bone, middle ear, and inner ear structures. The report details any evidence of infection, bone fractures, tumors, or other pathological changes affecting hearing or balance. The findings help guide treatment decisions or surgical planning.
Short Statement:
A precise CT scan of the temporal bones near the ears — essential for diagnosing chronic ear infections, fractures, tumors, or structural causes of hearing and balance problems.
