What is a common indicator of inflammation in an ear canal exam?

A narrowed ear canal is a common indicator of inflammation during an ear canal exam. Inflammation can lead to swelling and thickening of the ear canal's tissues, which in turn results in a narrowing of the canal. This change is significant as it may restrict airflow and drainage, potentially leading to an accumulation of fluids or discharge within the ear. This narrowing indicates that the body is responding to an irritant or infection, which is characteristic of inflammatory processes.

While other indicators may provide information about ear health, such as the presence of wax, discharge, or odor, they do not specifically point to inflammation. Clear discharge often suggests a non-infectious condition, while strong odors can be associated with bacterial growth, but do not solely indicate inflammation. Therefore, a narrowed ear canal is a distinctive sign emphasizing the inflammation's physical impact on the ear.
