Final answer:
The rupture of the tympanic membrane, or a perforated eardrum, can be caused by a head impact or conditions like chronic inflammation and AOM, leading to impaired conductive hearing.
Step-by-step explanation:
The rupture of the tympanic membrane, often referred to as a perforated eardrum, occurs when there is a tear or hole in the thin tissue that separates the ear canal from the middle ear. This condition can be caused by various factors, including diffuse impact to the head, chronic inflammation, or increased pressure due to a buildup of fluid in the middle ear, often associated with acute otitis media (AOM).
AOM is characterized by the formation and accumulation of pus in the middle ear due to an infection, leading to potential hearing loss and requiring medical attention. A healthy tympanic membrane is integral for conductive hearing, as it transports soundwave vibrations through the ossicles in the middle ear. When ruptured, the transfer of sound is impaired, resulting in hearing challenges or loss.
