ENT: Conductive Hearing Loss: Free MSRA Podcast

⚕️ FREE MSRA PODCAST – Conductive Hearing Loss🎧 A clear, high-yield breakdown of this mechanical hearing problem – perfect for exam prep and real-life clinical scenarios.🧠 Key Learning Points📌 Definition• Conductive hearing loss is caused by problems transmitting sound waves through the outer or middle ear to the inner ear.• Commonly results from obstruction, infection, or ossicle dysfunction.📌 Causes & Risk Factors• Cerumen impaction (earwax)• Otitis media (especially in children)• Tympanic membrane perforation• Otosclerosis (fixation of stapes)• Eustachian tube dysfunction or effusion ("glue ear")• Trauma or congenital defects• Risk ↑ with recurrent infections, trauma, family history of otosclerosis📌 Pathophysiology• Disruption in sound conduction from external ear → tympanic membrane → ossicles → cochlea• Sound energy fails to efficiently reach the inner ear → reduced hearing sensitivity📌 Symptoms• Muffled hearing• Feeling of fullness or pressure in the ear• Tinnitus• Hearing better in noisy environments (Paracusis of Willis)• Otalgia (if infective)• Children may present with speech delay or irritability🎧 Mnemonic: WET POT – Wax, Effusion, Trauma, Perforation, Otosclerosis, Tumour📌 Differential Diagnosis• Sensorineural hearing loss• Mixed hearing loss• Otitis externa• Eustachian tube dysfunction• Ear canal obstruction📌 Diagnosis• Otoscopy (e.g. wax, red drum, perforation, glue ear)• Rinne test: BC > AC (Rinne negative)• Weber test: Lateralises to affected ear• Pure tone audiometry: Air-bone gap• Tympanometry for middle ear function💡 Tip: Rinne = “Reverse” in conductive loss!📌 Management• Treat underlying cause (wax removal, antibiotics, surgery)• Avoid cotton buds• ENT referral for persistent or structural causes• Grommets for glue ear• Stapedectomy for otosclerosis• Hearing aids or bone conduction devices (especially vital in children)• Early intervention in kids prevents speech/language delay📌 Complications• Persistent hearing loss• Social withdrawal, speech/language delay in children• Chronic infections or recurrence• Missed inner ear pathology if misdiagnosed📌 Prognosis• Excellent if cause is treatable (e.g. wax, infections)• Variable with structural issues like otosclerosis• Early detection = better outcomes, especially in paediatric patients📎 More MSRA Resources for Conductive Hearing Loss📝 Revision Notes: https://www.passthemsra.com/topic/conductive-hearing-loss-revision-notes/🧠 Flashcards: https://www.passthemsra.com/topic/conductive-hearing-loss-flashcards/💬 Accordion Q&A Notes: https://www.passthemsra.com/topic/conductive-hearing-loss-accordion-qa-notes/🚀 Rapid Quiz: https://www.passthemsra.com/topic/conductive-hearing-loss-rapid-quiz/🎓 Full Course: https://www.passthemsra.com/courses/ent-for-the-msra/Hashtags#MSRA #MSRARevision #MSRATextbook #MSRAQuiz #MSRAQuestionBank #MSRAFlashcards #MSRAQandANotes #MSRAAccordions #MultiSpecialityRecruitmentAssessment #MSRAOnlineRevision #MSRARevisionWebsite #ENT #ConductiveHearingLoss
