What is the location of the external ear?

The external ear is defined as the outer part of the ear that is visible externally. It consists of the pinna (or auricle) and the external auditory canal, leading up to the eardrum. This structure plays a crucial role in collecting sound waves and funneling them into the ear canal, where they eventually reach the eardrum.

Understanding the anatomy of the ear is essential in medical coding and documentation, as it assists in accurately coding procedures or diagnoses related to ear conditions. The internal and middle ear structures serve different functions and are not considered part of the external ear. This distinction is key in both anatomy and in practical applications like coding, where precise terminology is vital.
