What effect does TM scarring have on the tympanic membrane?

Increases resistance to infection
Enhances mobility
Restricts mobility
Promotes healing

The correct answer is: Restricts mobility

Tympanic membrane (TM) scarring, often resulting from repeated infections or trauma, alters the structure of the membrane. In particular, scarring can lead to a thicker and less flexible membrane, which significantly hampers its ability to vibrate freely in response to sound waves. This restriction in mobility affects both hearing and balance, as the tympanic membrane plays a crucial role in transmitting sound energy to the middle ear. Understanding the effects of TM scarring helps in identifying potential complications and treatment options for individuals with a history of ear infections or injuries. While healthy tympanic membranes can move efficiently, scarring disrupts this process, underscoring the importance of maintaining ear health to prevent such conditions.
