Chapter 122 - Part B: Different Causes, Same Disease: Otitis Externa
Use Left/Right to seek, Home/End to jump to start or end. Hold shift to jump forward or backward.
In this BoardsCast episode, we continue Tobias Chapter 122 — Pinna and External Ear Canal with the key clinical truth that stops the endless “drops → better → relapse” cycle:
Otitis externa is one disease with many triggers — and the trigger isn’t the same thing as the mechanism.
The mechanism is always the same: The ear stops cleaning itself.
Once airflow, drainage, and epithelial migration (the “conveyor belt”) fail, normal organisms become opportunists, inflammation amplifies, and the canal begins remodeling into stenosis, fibrosis, and mineralization.
This episode gives you the board's framework that makes chronic ear disease predictable:
- Primary causes light the match (allergy, mites, foreign body, keratinization disorders)
- Predisposing factors pour gasoline (pendulous ears, narrow canals, hair, moisture)
- Perpetuating factors keep it burning (stenosis, fibrosis, mineralization, chronic infection)
Key takeaway: Cytology tells you who’s partying. Your job is figuring out why the building flooded.
