ENT: Ramsay Hunt Syndrome: Free MSRA Podcast

✅ MSRA Deep Dive: Ramsay Hunt SyndromeIn this high-yield ENT episode, we break down Ramsay Hunt Syndrome, a serious complication of varicella-zoster virus (VZV) reactivation. Often misdiagnosed or confused with Bell’s palsy, this deep dive helps you understand the classic signs, crucial differentiators, and why prompt treatment is essential for the best outcomes.🧠 Key Learning Points📌 DefinitionRamsay Hunt Syndrome (RHS) is caused by reactivation of VZV in the geniculate ganglion, affecting cranial nerves VII (facial) and sometimes VIII (vestibulocochlear). It’s essentially shingles involving the ear with facial palsy.📌 Causes & Risk Factors• Reactivation of dormant varicella-zoster virus• Common triggers: age >60, immunosuppression, stress, or post-viral immune dip• Must have had prior chickenpox📌 PathophysiologyThe virus spreads along sensory and motor fibres, causing inflammation, nerve damage, and painful vesicular rash. Affects taste, hearing, balance, and facial motor control.📌 Symptoms• Triad: Severe ear pain, unilateral facial paralysis, and vesicular rash around the ear (herpes zoster oticus)• Additional features:– Hearing loss (sensorineural)– Tinnitus– Vertigo– Hyperacusis– Loss of taste– Dry mouth or eyes• Note: Can present without rash (zoster sine herpete)📌 Key Clinical Clues• Lower motor neuron pattern of facial palsy (entire side affected including forehead)• Pain + rash = suspect RHS over Bell’s palsy• Sudden onset ear pain before rash or paralysis may occur• Keep broad differentials early: Bell’s palsy, stroke, otitis media, Lyme disease, trigeminal neuralgia, neoplasms📌 Investigations• Clinical diagnosis is primary• PCR of vesicle fluid or saliva to confirm VZV• Audiometry for hearing loss• MRI if no clear cause or atypical presentation• Check for immune compromise if recurrent📌 Management• Start early: Ideally within 72 hours• Combination treatment:– Oral aciclovir (or valaciclovir)– Prednisolone (corticosteroids)• Eye protection: Lubricating drops, taping shut at night• Pain control: Carbamazepine or other neuropathic agents• Vestibular suppressants: Antihistamines, anticholinergics• Supportive care: Physio, counselling, recovery monitoring📌 Prognosis• Approx. 75% recover full facial movement• Worse outcomes if: older, diabetic, hypertensive, or present with vertigo• Hearing loss often recovers (only 5% persistently affected)📌 Complications• Post-herpetic neuralgia• Permanent facial weakness• Chronic tinnitus• Corneal damage (from inability to blink)• Vestibular dysfunction• Scarring or secondary infection of lesions🔗 MSRA Ramsay Hunt Syndrome Resources📄 Revision Notes: https://www.passthemsra.com/topic/ramsay-hunt-syndrome-revision-notes/💬 Flashcards: https://www.passthemsra.com/topic/ramsay-hunt-syndrome-flashcards/🧠 Accordion Q&A: https://www.passthemsra.com/topic/ramsay-hunt-syndrome-accordion-qa-notes/📝 Rapid Quiz: https://www.passthemsra.com/topic/ramsay-hunt-syndrome-rapid-quiz/🎯 ENT Quiz Hub: https://www.passthemsra.com/quizzes/ramsay-hunt-syndrome/📚 ENT Course: https://www.passthemsra.com/courses/ent-for-the-msra/🏷️ Hashtags#MSRA #MSRARevision #ENTMSRA #RamsayHuntSyndrome #FacialPalsy #Shingles #VZV #ENTRevision #MSRAFlashcards #MSRAQuestionBank #PassTheMSRA #FreeMSRA #HerpesZosterOticus #MedicalRevision
