This guide covers everything your examiner is likely to ask. Here is a quick orientation of what is inside:
What this covers:
  1. ENT Anatomy - Complete breakdown of the external/middle/inner ear (TM layers, middle ear walls, Eustachian tube facts, ossicles), nose (Kiesselbach's plexus, turbinates, paranasal sinus drainage), pharynx, and larynx with nerve supply.
  2. Key ENT Pathology - Rapid-fire tables for common ear, nose, and throat conditions.
  3. Investigations - Tuning fork interpretation (Rinne/Weber), tympanometry types, and audiological tests.
  4. CSOM - Full Deep Dive:
    • Two types: Tubotympanic (safe/central perforation) vs. Atticoantral (dangerous/attic perforation + cholesteatoma)
    • Complete pathogenesis step-by-step from ET dysfunction → mucosal inflammation → retraction pocket → cholesteatoma
    • All symptoms with danger signs explained
    • Detailed local examination findings for both types
    • Medical (aural toilet + topical fluoroquinolones) and surgical (myringoplasty / CWU vs. CWD mastoidectomy) treatment
    • Full complications list: Gradenigo's syndrome, Griesinger's sign, lateral sinus thrombosis
  5. High-Yield Viva Q&A - 12 rapid questions with model answers
Key things to remember for tomorrow:
  • Attic perforation + offensive discharge = cholesteatoma = dangerous = surgery always
  • Otalgia in CSOM = red flag (complication/malignancy)
  • Only fluoroquinolone drops are safe (NOT aminoglycosides) when TM is perforated
  • Prussak's space = where cholesteatoma starts in pars flaccida disease
