The initial pathogenesis associated with external otitis media, particularly in cases linked to swimming, primarily involves the breakdown of the skin-cerumen barrier. When a person swims, water can enter the ear canal, affecting the delicate balance of moisture and cerumen (earwax) that typically protects the skin lining of the ear canal.

This barrier is important as it serves as a defense mechanism against pathogens and maintains the integrity of the skin. If this barrier is compromised, the skin becomes more susceptible to irritation and infection by bacteria or fungi that may be present in the water, leading to inflammation and symptoms of external otitis media.

Thus, the breakdown of this protective barrier is a significant precursor to developing the condition, making it crucial to understand this aspect in the context of swimming-related external otitis. The other options, while related to ear conditions, do not directly address the initial pathogenesis in the specific context of swimming-related external otitis.
