What describes the characteristic of otorrhea?

Otorrhea refers specifically to a discharge from the ear, particularly the outer ear, which is often a result of an underlying infection such as otitis externa or otitis media. This discharge can vary in appearance and consistency, depending on the nature and severity of the infection, and it may include pus, blood, or clear fluid. Understanding this term is crucial for identifying and managing ear-related health issues, as it indicates the presence of an inflammatory process or infection in the ear region.

Fluid buildup in the inner ear pertains to a different condition, typically associated with inner ear disorders rather than discharges from the outer ear. Congenital absence of ear structures refers to developmental anomalies rather than a symptomatic discharge. Lastly, blockage of the ear canal does not describe a discharge; it indicates an obstruction that may lead to infection but does not by itself result in otorrhea. Thus, the option about discharge due to infection aligns perfectly with the definition of otorrhea.
