ENT: Presbycusis - Age-Related Hearing Loss: Free MSRA Podcast

🎧 FREE MSRA PODCAST – Presbycusis (Age-Related Hearing Loss): Causes, Diagnosis & ManagementExplore presbycusis—the most common cause of hearing loss in older adults. This high-yield revision episode covers the underlying causes, clinical features, diagnosis, management, and the wider impacts of age-related hearing loss. Essential listening for exam revision or practical ENT knowledge!🧠 Key Learning PointsDefinition• Presbycusis = progressive, bilateral, sensorineural hearing loss due to ageing• Affects high-frequency sounds first; gradual onsetCauses & Risk Factors• Natural ageing of the auditory system• Family history and genetic predisposition• Lifetime noise exposure (occupational, recreational)• Cardiovascular disease, arteriosclerosis• Diabetes (accelerates vascular damage)• Smoking• Ototoxic drugs (e.g. aspirin, some chemotherapy)• Oxidative stressPathophysiology• Degeneration of cochlear hair cells (especially high-frequency)• Atrophy of auditory nerve fibres• Reduced blood supply to inner ear structuresSymptoms• Difficulty hearing high-pitched sounds• Trouble understanding speech, especially in noisy places• Need to increase TV/radio volume• Speech sounds muffled/distorted• Tinnitus (ringing/buzzing)• Rarely, hyperacusis (increased sensitivity to sound)Diagnosis• Clinical: History, otoscopy (usually normal)• Audiology: Pure tone audiometry (high-frequency sensorineural loss), speech audiometry• Tympanometry (normal in presbycusis)• Blood tests only if another cause suspected• Rule out: conductive causes (wax, middle ear disease), central processing issuesManagement• Hearing aids (mainstay)• Assistive listening devices (amplified phones, TV systems)• Communication strategies (face-to-face, clear speech, minimise background noise)• Auditory rehabilitation and support• Cochlear implants for severe/profound cases• Manage modifiable risk factors (cardiovascular health, noise exposure, avoid ototoxins)Complications• Social isolation and withdrawal• Depression, anxiety• Communication difficulties affecting relationships and work• ↑ Risk of falls and accidents• Reduced quality of life📎 More Presbycusis Revision Resources:📝 Revision Notes: https://www.passthemsra.com/topic/presbycusis-revision-notes/💬 Flashcards: https://www.passthemsra.com/topic/presbycusis-flashcards/🧠 Q&A Notes: https://www.passthemsra.com/topic/presbycusis-accordion-qa-notes/📝 Rapid Quiz: https://www.passthemsra.com/topic/presbycusis-rapid-quiz/🎯 Quiz Portal: https://www.passthemsra.com/quizzes/presbycusis/📚 ENT Course: https://www.passthemsra.com/courses/ent-for-the-msra/🏷️ Hashtags#MSRA #Presbycusis #ENTRevision #AgeRelatedHearingLoss #MSRAENT #MSRAFlashcards #MedicalRevision #SensorineuralHearingLoss #PassTheMSRA #FreeMSRA #HearingHealth #MedicalPodcast #HealthyAging
