A type B tympanogram typically indicates which of the following?

A type B tympanogram is characterized by a flat line on the graph, indicating that there is little to no movement of the tympanic membrane in response to changes in air pressure. This typically signals that there is a significant problem affecting the middle ear.

Specifically, a type B reading often indicates the presence of fluid in the middle ear, commonly seen in conditions like otitis media, or it may suggest cerumen blockage in the ear canal. The lack of compliance shown in the type B tympanogram reflects that the transmission of sound is impeded, which aligns with either fluid accumulation or a physical blockage, making this option the correct interpretation of a type B tympanogram.

In contrast, the other options refer to specific conditions that would not produce the same tympanogram results. Discontinuity of the ossicles or otosclerosis typically results in a type A or a type C tympanogram, reflecting more mobility or normal function of the middle ear structure. A normal ear pressure and compliance would correspond with a type A tympanogram, which shows typical movement of the tympanic membrane and indicates a healthy middle ear.
