ENT: Perforated Eardrum: Free MSRA Podcast

⚕️ FREE MSRA PODCAST – Perforated Tympanic Membrane🎧 A clear, high-yield breakdown of this common ENT condition – perfect for exam prep and real-life clinical scenarios.🧠 Key Learning Points📌 Definition• A perforated tympanic membrane (aka ruptured eardrum) is a hole or tear in the eardrum, the membrane separating the outer and middle ear.• Leads to hearing loss and increased risk of middle ear infections.📌 Causes & Risk Factors• Most common cause: Middle ear infection (acute otitis media)• Trauma – e.g. cotton bud injury• Barotrauma – from flying or diving• Acoustic trauma – loud noises• Spontaneous rupture• Risk factors:Cotton bud useRecurrent infectionsLoud noise exposureScuba diving / flyingHistory of ear surgery💡 Mnemonic: “POP EAR” = Pressure, Otitis media, Poke, Exposure (noise), Altitude, Rupture📌 Pathophysiology• Eardrum disruption leads to:Loss of sound vibration → conductive hearing lossEntry point for pathogens → risk of infection• Direct connection forms between external canal and middle ear📌 Symptoms• Ear pain• Hearing loss• Otorrhea (discharge)• Tinnitus (ringing)• Vertigo (sometimes)• Visible perforation on exam💡 Classic case: Sudden hearing loss + ear discharge after infection or trauma📌 Differential Diagnosis• Otitis media (with/without perforation)• Otitis externa• Middle ear effusion• Earwax impaction• Always perform otoscopy to confirm📌 Diagnosis🔍 Otoscopy – visualises perforation🎧 Audiometry – assesses hearing levels📊 Tympanometry – tests middle ear pressure and movement🖼️ CT scan – only if complications suspected💡 Key tip: Always examine the ear – diagnosis is visual📌 Management🩺 Conservative (majority):• Most perforations heal within 6–8 weeks• Avoid water in the ear during healing💊 Antibiotics – only if underlying infection present🔧 Surgical (if not healing):• Myringoplasty – surgical closure of eardrum💡 Core plan: Watch, protect from water, intervene if persistent📌 Complications• Chronic or recurrent otitis media• Persistent hearing loss• Cholesteatoma – abnormal skin growth in middle ear• Tympanosclerosis – scarring of the membrane• Rare: Injury to ossicles or facial nerve💡 Prevention = avoid moisture, follow up for healing📌 Prognosis• Generally excellent• Most cases heal spontaneously• Outcome depends on size/location, presence of infection, and patient factors📎 More MSRA Resources for Perforated Tympanic Membrane📝 Revision Notes:https://www.passthemsra.com/topic/perforated-tympanic-membrane-revision-notes/🧠 Flashcards:https://www.passthemsra.com/topic/perforated-tympanic-membrane-flashcards/💬 Accordion Q&A Notes:https://www.passthemsra.com/topic/perforated-tympanic-membrane-accordion-qa-notes/🚀 Rapid Quiz:https://www.passthemsra.com/topic/perforated-tympanic-membrane-rapid-quiz/🎯 Topic Quiz:https://www.passthemsra.com/quizzes/perforated-tympanic-membrane/🎓 Full Course (ENT):https://www.passthemsra.com/courses/ent-for-the-msra/🎧 Whether you're revising ear conditions or spotting red flags in clinic, this episode gives you all the high-yield facts to master this common yet easily overlooked ENT diagnosis.Hashtags#MSRA #MSRARevisionNotes #MSRAQuiz #MSRAFlashcards #MSRAQuestionBank #MSRAQandANotes #MSRAAccordions #MultiSpecialityRecruitmentAssessment #MSRAOnlineRevision #MSRARevisionWebsite #ENT #PerforatedTympanicMembrane #RupturedEardrum #OtitisMedia #TympanicMembrane #MSRADeepDive
