During an otoscope examination, what should you ensure you can visualize?

In an otoscope examination, the primary focus is to visualize the tympanic membranes. The tympanic membrane, commonly known as the eardrum, is a crucial structure in the ear that plays a significant role in hearing by vibrating in response to sound waves. Observing the tympanic membranes allows the examiner to assess their integrity, appearance, and any signs of disease or infection, such as fluid accumulation, perforations, or inflammation.

In contrast, eardrum migration refers to changes in the positioning or movement of the membrane, which is not typically assessed directly during an otoscopic exam. The external ear structure is also important, but it serves more as an entry point for the otoscope rather than the primary focus of the examination. Additionally, the parotid gland is unrelated to otoscopic examination; it is a salivary gland located near the ear but does not pertain to the examination of the tympanic membranes or inner ear structures. Focusing on the tympanic membranes is essential for determining the health and function of the auditory system.
