What might be a common consequence of untreated otitis externa?

The consequence of untreated otitis externa that is most commonly recognized is hearing loss. This condition, often referred to as swimmer’s ear, involves inflammation and infection of the external auditory canal. As the inflammation progresses, it can lead to swelling that narrows the canal, impeding sound transmission. Moreover, accumulated discharge and debris can contribute to conductive hearing loss.

In the context of untreated otitis externa, the blockage or changes within the external ear canal can significantly affect hearing abilities, especially in more severe or chronic cases. Addressing the infection early through appropriate treatment can help prevent this consequence.

The other possibilities, while they may occur in certain situations involving ear conditions, are less direct consequences of otitis externa. Cerumen impaction typically occurs due to excessive wax build-up or improper cleaning techniques rather than as a direct result of otitis externa. Facial nerve damage is more associated with middle ear issues or specific infections that affect deeper structures of the ear. While a perforated eardrum can be a concern with some ear conditions, it is not the primary outcome associated directly with otitis externa; it is more commonly seen in cases of acute otitis media or trauma.
