What does "ad" or "AD" refer to in ear examinations?

In the context of ear examinations, "ad" or "AD" stands for "auris dextra," which is a Latin term meaning "right ear." This terminology is commonly used in medical settings to specify the ear that is being referenced in examinations, prescriptions, or procedures. Understanding this abbreviated form is important for accurate communication among healthcare providers concerning patient care.

In contrast, alternatives such as "au" signify both ears, while "as" or "AD" indicate the left ear (auris sinistra). Distinguishing between these terms is vital to avoid confusion in the administration of treatments and medication, which can significantly impact patient safety and outcomes. Knowing that "AD" refers to the right ear enables healthcare providers to document and communicate effectively about patient assessments and interventions.
