Which tool is primarily used for direct examination of the external ear structure?

• A. Otoscope
• B. Audiometer
• C. Tympanometer
• D. Acoustic reflectometer

Answer: (A)

The tool that enables direct visualization of the external ear canal and eardrum is the otoscope. It combines a small light and magnification with a short cone (speculum) that sits in the ear canal, allowing you to inspect the canal walls, any cerumen buildup, signs of infection, and the tympanic membrane itself. The other devices serve different purposes: an audiometer checks hearing thresholds, a tympanometer assesses middle-ear pressure and tympanic membrane movement, and an acoustic reflectometer gauges how sound is reflected to infer middle-ear status. For directly examining the external ear structure, the otoscope is the instrument of choice.
