If both ears are affected, what term is typically used?

The term that is typically used when both ears are affected is "bilateral." This term is derived from the Latin "bi-" meaning "two" and "latus," meaning "side." Therefore, bilateral conditions involve both sides of the body. In a medical context, when a patient presents with issues or conditions in both ears, it is accurately described as bilateral involvement.

In contrast, the term "unilateral" refers to conditions that occur on only one side of the body, which would not apply in this scenario. The terms "single" and "parallel" are not commonly used in this context. "Single" generally indicates one item or instance, while "parallel" does not pertain specifically to affliction or condition but rather refers to things that are similar or occur in a comparable manner. Thus, the use of "bilateral" clearly captures the description of a condition affecting both ears.
