Ear Pathology MindMap

Presentation · PPTX

What's Inside (4 slides, deep navy theme)

Slide 1 - Title

Bold visual intro with a designed color palette: red center, blue (middle ear), teal (inner ear).

Slide 2 - Middle Ear Pathology Mind Map

Radial layout with 7 branches from a central "Middle Ear Pathology" node:
BranchKey Content
Otitis MediaAOM (S. pneumoniae, H. flu, M. catarrhalis), OME/Glue ear, CSOM (tubo-tympanic/atticoantral), Bullous myringitis
CholesteatomaCongenital vs acquired, pars flaccida/tensa retraction, complications (SNHL, facial palsy, intracranial), CWU vs CWD surgery
TM DisordersPerforation, myringosclerosis/tympanosclerosis, atelectasis/retraction pocket
MastoiditisAcute coalescent, Bezold's abscess, CT findings, IV abx + mastoidectomy
OtosclerosisStapes footplate fixation, AD inheritance, female > male, stapedectomy
ComplicationsIntracranial (meningitis, brain abscess, lateral sinus thrombosis), labyrinthine fistula (10-15% of CSOM)
Eustachian Tube DysfunctionObstructive vs patulous ETD

Slide 3 - Inner Ear Pathology Mind Map

7 branches from central "Inner Ear Pathology" node:
BranchKey Content
Ménière DiseaseEndolymphatic hydrops, the classic tetrad, SP:AP ratio >0.4, IT gentamicin/steroids
Vestibular SchwannomaMost common IAC/CPA tumor, Antoni A & B histology, MRI + Gd gold standard, observe/radiosurgery/microsurgery
BPPVOtolith debris in posterior SCC, Dix-Hallpike test, Epley maneuver
Vestibular Neuritis / LabyrinthitisHSV-1 reactivation, HIT test, VN (no hearing loss) vs labyrinthitis (hearing loss)
SNHLNIHL (4 kHz notch), sudden SNHL (steroids), presbycusis, ototoxicity (aminoglycosides/cisplatin)
Perilymph Fistula & InfectionsRound/oval window tear, suppurative labyrinthitis, autoimmune inner ear disease (AIED)
Tinnitus & OtherSubjective vs objective, cochlear implant indications

Slide 4 - Clinical Quick Reference Table

12-row table covering every disease with: key features, investigations, and treatment - sourced from Cummings Otolaryngology, Scott-Brown's ORL, KJ Lee's Essential Otolaryngology, and Rosen's Emergency Medicine.
