International Licensing Examination (ILE) Practice Test

Anotia specifically refers to the congenital condition where there is a complete absence of one or both external ears. This may occur as a result of developmental issues during pregnancy and can vary in severity. Understanding this medical term is essential, particularly in fields related to audiology, otology, or pediatrics, where such conditions may significantly impact the patient’s quality of life and require early intervention.

The other choices relate to various ear conditions but do not define anotia. Inflammation of the external ear refers to conditions like otitis externa, which involves swelling and redness due to infection or irritation. The narrowing of the ear canal, known as external auditory canal stenosis, can cause hearing problems but is distinctly different from anotia. A bony growth in the external ear canal, often referred to as exostosis, pertains to abnormal bone growth rather than absence. Each of these conditions has its distinct characteristics and implications, clearly differentiating them from anotia.
