Kulak zarı, also known as the eardrum, is a thin membrane located in the ear that separates the outer ear from the middle ear. It plays a crucial role in hearing by vibrating in response to sound waves, which then transmit these vibrations to the tiny bones in the middle ear. When the kulak zarı is damaged, it can lead to hearing loss or infections. Common causes of damage include loud noises, infections, or physical trauma. Treatment options vary depending on the severity of the damage and may include medication or surgical procedures to repair the membrane.
