ENT: Cholesteatoma: Free MSRA Podcast

🎧 FREE MSRA PODCAST – Cholesteatoma: The Silent Ear DestroyerCholesteatoma may be non-cancerous, but it’s one of ENT’s most destructive middle ear conditions. In this episode, we break down your revision notes into easy-to-remember, high-yield facts—covering definition, causes, symptoms, investigations, management, complications, and the vital pearls you need for exams and practice!📝 Key Learning Points🦻 Definition & Overview• Cholesteatoma = abnormal, destructive growth of keratinising squamous epithelium (skin cells) in the middle ear.• Forms a sac that expands and erodes bone and local structures.👶 Types• Congenital (rare, ~2%): epithelial cells trapped in early development; usually presents as hearing loss in children, often found incidentally.• Acquired (common): linked to chronic ear disease; subdivided into:– Primary (eustachian tube dysfunction → retraction pocket → trapped epithelium)– Secondary (direct entry after perforation/trauma/chronic infection)🚩 Risk Factors• Chronic or recurrent otitis media, poor eustachian tube function, cleft palate, history of ear surgery or trauma, lower socioeconomic status, male sex.⚙️ Pathophysiology• Abnormal skin cells migrate into the middle ear, accumulate keratin, and release enzymes that erode ossicles, mastoid, and nearby bone—can eventually threaten the inner ear and brain!🩺 Clinical Features• Classic: painless, persistent, foul-smelling ear discharge (otorrhoea); unilateral conductive hearing loss.• Other: recurrent infections, tinnitus, dizziness, feeling of fullness, (late) vertigo, facial weakness, headache.• Red flags: vertigo, facial palsy, CNS symptoms—think complications!🔍 Diagnosis• Otoscopy: “attic crust” (keratin debris in upper eardrum), retraction pocket, or visible perforation; granulation tissue possible.• Imaging: CT temporal bones for extent and bony erosion; MRI if intracranial spread or soft tissue involvement suspected.🩹 Management• Surgical removal is the ONLY definitive treatment—usually tympanomastoidectomy (open or closed approach).• Open = better clearance, but lifelong cavity care; closed = better cosmesis, but higher recurrence (may need “second-look” surgery).• Antibiotics for infection only—not curative. Regular follow-up is essential due to recurrence risk (up to 30%!).⚠️ Complications• Permanent hearing loss, mastoiditis, facial nerve palsy, chronic dizziness, meningitis, brain abscess, intracranial spread, neck abscess.• Surgical risks: taste disturbance, ear canal narrowing, persistent dizziness, rare facial nerve injury.🔗 Prognosis• Favourable with early diagnosis and full excision; recurrence or disease in the other ear possible—lifelong follow-up is key.📎 More Cholesteatoma Revision Resources:📝 Revision Notes: https://www.passthemsra.com/topic/cholesteatoma-revision-notes/🧠 Flashcards: https://www.passthemsra.com/topic/cholesteatoma-flashcards/💬 Accordion Q&A: https://www.passthemsra.com/topic/cholesteatoma-accordion-qa-notes/🚀 Rapid Quiz: https://www.passthemsra.com/topic/cholesteatoma-rapid-quiz/🧪 Quiz Bank: https://www.passthemsra.com/quizzes/cholesteatoma/🎓 Full Course: https://www.passthemsra.com/courses/ent-for-the-msra/#MSRA #Cholesteatoma #ENT #MSRARevision #EarDischarge #HearingLoss #Otology #PassTheMSRA #HighYield #ExamPearls #Keratin #NICEGuidelines #MedicalRevision
