In this BoardsCast episode, we continue Tobias Chapter 123 — Middle and Inner Ear with the highest-stakes clinical transition in otitis:

The disease didn’t change. The ZIP code did.

A patient walks in with “an ear infection”… and suddenly has a head tilt, facial droop, Horner syndrome, and ataxia. That’s not because the bacteria got smarter — it’s because middle ear disease lives next to critical neurologic real estate. 

You’ll learn:

  •  Why the facial nerve (CN VII) is vulnerable in otitis media (including the “incomplete canal” problem) — and why loss of blink becomes a corneal emergency 
  •  How chorda tympani involvement can reduce tear production and worsen exposure injury 
  •  Why ventral bulla inflammation can create Horner syndrome (miosis, ptosis, enophthalmos, third eyelid protrusion) 
  •  How otitis media crosses the round/oval window to become otitis interna → vestibular dysfunction, nystagmus, ataxia, hearing loss 
  •  When it becomes a true neuro case: intracranial extension (central signs, altered mentation, seizures) — and why MRI is the tool when brain tissue is involved 

Key takeaway: Once neurologic signs appear, this is no longer “just an ear.”
