Microtic means:

Microtic specifically refers to a condition where there is an abnormal reduction in the size of the pinna, which is the outer part of the ear. This condition is often congenital, meaning that it is present at birth. Individuals with microtia may have a pinna that is smaller than normal or may have developmental anomalies affecting its structure.

This understanding of microtia is critical in audiology practice, as it can impact hearing and may require specialized assessment and management strategies, such as fitting for hearing aids or surgical interventions. The term derives from the Greek "micros," meaning small, and "otia," relating to the ear, further solidifying its definition within medical terminology.
