Interest of the Cone-beam Computed Tomography in the Imagery of the Middle Ear

Cone beam computed tomography (CBCT), is a recent medical imaging technique where the X-rays are divergent, forming a cone.

As a result, this technique is less irradiating that the scanner. The purpose of this exploratory study is to compare the performance of the scanner and the cone beam in the detection of anatomical structures of the ear.

Inclusion Criteria:

• Adult patient
• Indication of a CT scan of the ear
• Written and signed informed consent by the patient to participate in the study

Exclusion Criteria:

• Pregnancy
• Breast feeding
• Patient under a legal protection procedure
• Lack of affiliation to a social security system
