Diagnosis Diagnosis begins with a detailed history, including possible related injuries, such as upper respiratory infections or head injury. The examination may involve nasal endoscopy for obstructive factors such as polyps or swelling. A nervous system examination is performed to see if the cranial nerves are affected. On occasion, after head traumas, there are people who have unilateral anosmia. The sense of smell should be tested individually in each nostril.
