What term describes the outward bulging of the tympanic membrane?

The term used to describe the outward bulging of the tympanic membrane is known as "bulging TM." This condition indicates that fluid or pressure is accumulating in the middle ear, often due to an infection or other underlying issues. In a clinical setting, a bulging tympanic membrane is often associated with otitis media, where it may appear tense and domed due to the increased pressure from the middle ear space. This presentation helps healthcare professionals assess the severity of an ear condition and decide on appropriate interventions.

In contrast, a retracted tympanic membrane occurs when the membrane is pulled inward, which can indicate eustachian tube dysfunction. A normal tympanic membrane would have a flat and translucent appearance, indicating good health without any signs of fluid or other abnormalities. An erythematous tympanic membrane refers to a reddened appearance, often a sign of inflammation or infection, but does not specifically indicate bulging. Hence, "bulging TM" accurately describes the condition where the tympanic membrane protrudes outward due to pressure changes.
