An instrument used to examine the ear canal and tympanic membrane is called what?

• A. Stethoscope
• B. Endoscope
• C. Otoscope
• D. Ophthalmoscope

Answer: (C)

An otoscope is designed specifically to visualize the ear canal and tympanic membrane. It combines a light, a magnifying lens, and a disposable speculum that fits into the ear canal, allowing you to illuminate and closely inspect the drum and surrounding structures. This setup helps assess the drum’s color, contour, and integrity, and to detect signs of infection, fluid behind the drum, or perforation. Some models also have a pneumatic feature to test tympanic membrane mobility. The stethoscope is for listening to heart and lung sounds and isn’t used for visualizing the ear. An endoscope is a general instrument for examining internal passages in various parts of the body, not the standard tool for routine ear exams. The ophthalmoscope is used to examine the eye.
