Damage to the tympanic membrane can be caused by?

Damage to the tympanic membrane can be caused by?

• A. Chronic otitis media
• B. Excessive exposure to high-amplitude sounds
• C. Chronic otitis media or excessive exposure to high-amplitude sounds
• D. Aging of the tympanic membrane

Answer: (C)

The tympanic membrane is a delicate structure that can be damaged by two main pathways: chronic infection/inflammation and strong mechanical stress from loud sounds. Chronic otitis media keeps the middle ear inflamed and can erode the edge of the membrane or cause scarring and perforation, weakening its integrity. Exposures to high-amplitude sounds deliver large pressure waves to the membrane, which can tear it outright or cause rupture from acoustic trauma. Aging can alter its properties to some extent but is not a common direct cause of acute damage like perforation. So both chronic infection and loud noise are established ways the tympanic membrane can be damaged.
