  1. E.N.T. – (Illustrated!) Dr Katie Bleksley GPST1

  2. Aims • To recognise and proficiently manage common ear conditions presenting to GP • Be aware of the some of the red flags to look out for wrt ear problems.

  3. Objectives • To be able to recognise infections of the ear: OE, furunculosis, HZV, OM. Understand the use of antibiotics in treating ear infections • Understand what to do with foreign bodies in the ear, and which substances require urgent removal. • Understand the risks/complications of ear trauma and how lacerations/haematomas and bites should be managed. • Assess deafness and appreciate the importance of sudden deafness. • Brief coverage of DDx for vertigo and tinnitus

  4. Primary Otitis Externa Otitis Media Furuncle Secondary/Referred pain TMJ Dental Throat pathology Sinuses LNs Facial Nerve Otalgia No obvious cause

  5. The normal TM • Long process of the incus • Handle of the malleus • pars tensa • Long arm of the malleus • pars flaccida G D A E F

  6. Otitis Externa

  7. Otitis Externa • Features • Pain – on movement of pinna • Itching • Deafness • Swollen / Inflamed canal • Discharge / Debris

  8. Otitis Externa • Management • Aural toilet needed in all but mild cases • Keep ear dry • Topical Antibiotic / Steroid: • Analgesia • Preventative advice: keep dry when swimming/bathing, no FBs in ear..

  9. Otitis Externa: ABx • Locorten vioform (flumethasone and clioquinol and iodine) 2-3drops bd 7-10days • Sofradex (dex and framycetin and gramicidin) 2-3drops tds/qds or Otomize (dex and neomycin): 1 spray tds or Ciloxan eye drops (cipro 0.3%) • Treat for > 7days • Swab before starting any second line treatment (?candida/aspergillus) and check sensitivities • For fungal OE use Clotrimazole 1% (canesten) drops tds for 14d after the infection has resolved.

  10. Caution, OE in diabetics…. Malignant OE • Infection of the EAC with pseudomonas • Infection can spread to soft tissues and bones Caution – Diabetics – Malig OE

  11. Furunculosis • Infection of hair follicles in outer third of ear canal. • Severe pain • O/E: Boil in the ear canal • Need to r/o DM • Rx: analgesia, gentisone HC drops 3 drops qds 7 days. Oral fluclox 7days if cellulitis

  12. Ramsey Hunt Synd (HZV) • Severe pain in ear precedes facial palsy • vesicles in the EAC/around the ext ear and on the soft palate. • +/- dizziness / vertigo • Aciclovir 800mg 5x/day for 1 wk if Dx <24h • Postherpetic neuralgia can be a problem

  13. Otitis Media

  14. Acute Otitis Media • Infection of the middle ear. • Bacterial/viral but impossible to distinguish clinically • Presentation: Pain, Deafness, URTI Sxs • O/E: Red, Bulging TM, +/- perforation and discharge

  15. Acute Otitis Media • Management • Analgesia • Consider oral antibiotics: amoxil tds (pen all.: erythro qds) for 5days if…. • Age <2 with bilat acute OM • If perforation present • ?? If >3days duration ?? • If sig. comorbidities • Or give a delayed script • Refer ENT if.. • Signs of complications/spread of infection • OM recurs/fails to respond give augmentin and refer. • acute perf. fails to heal within 1 month.

  16. Otitis Media – red flags 1 SIGNS OF COMPLICATIONS - mastoid tenderness / swelling - sudden deafness - dizziness with nystagmus - malaise / headache

  17. Mastoiditis Refer Immediately

  18. Otitis Media – red flags 2 • LOOK FOR A PERFORATION IN ANY DISCHARGING EAR • Acute central perf. is okay (but needs review in 1 month), • Attic perf. suggests cholesteatoma and merits referral. • If you can’t visualise the drum review the patient.

  19. Tympanic Perforation • Left TM central perforation Attic perforation with cholesteatoma

  20. Problematic OM • Recurrent acute OM: • Trimethoprim 1-2mg/kg od for 3months • Chr supp. OM If ear d/c in presence of chr (central) perforation treat as OE: • Gentisone HC 2 drops qds or Cipro 0.3% eye drops 2 drops tds • Red flags: persistent discharge despite the above or deafness/vertigo/attic perf. -> Refer ENT.

  21. Ear Injuries • Pinna Lacerations • Refer all but the most trivial • Human Bites • Refer all • Haematoma of the Pinna • Refer urgently to prevent cartilage necrosis

  22. Ear Injuries

  23. Deafness • Temporary deafness is common due to OM • Persistent hearing problems: • Hx and Ex • pay attention to developmental assessment in children, • take seriously and refer for audiology (formal audiometry possible if >3y) • Refer to ENT if: • Sudden onset deafness • Conductive hearing loss with no obvious cause • Asymmetrical deafness Sudden onset SN deafness is an ENT emergency

  24. Persistent Deafness - causes • Conductive: • Wax / FB • OME • Chr supp OM and cholesteatoma • Otosclerosis (bilat may be a FH, refer for surgery) • Sensorineural: • Presbyacusis (gradual bilat symm high freq loss in ppl >50y) • Acoustic neuroma (unilat/asymmet deafness)

  25. Wax in the ear • Olive oil tds for 5d • microsuction

  26. Foreign Bodies in the Ear

  27. What needs urgent removal? • Batteries • Biological material (eg dead insect*) • Signs of secondary infection • Urgent = same day • Non-urgent = within 3days * insects can be drowned in oil and then suctioned out

  28. OME

  29. OME • Hearing loss, +/- earache, developmental delay • Dull retracted drum with visible peripheral vessels, fluid level/air bubbles may be visible behind the drum • 75% resolve in <3months • Refer if persistent esp if causing speech/lang delay • Grommets: can swim/bathe, but avoid diving. If dicharge from ear treat with aural toilet and AB/steroid drops as for OE.

  30. Tinnitus • Severe tinnitus affects 2% of pop • DDx: may accompany hearing loss, meniere’s, noise exposure, head injury, HTN, drugs (loop diuretics, TCAs, aminoglycosides, aspirin, NSAIDs) but often no cause found. • Ix: audiometry if deafness • Rx: reassure, +/- refer to hearing therapist and tinnitus support group, masking. Unilat tinnitus (?acoustic neuroma), objective/pulsatile tinnitus (?vasc malformation)

  31. Vertigo – Hx gives Dx, Neuro Ex (esp cerebellar ex) essential to r/o pathol • Secs-mins : BPPV (postural, dix hallpike +ve) • Reasssure. Don’t give labyrinthine sedatives. Epley’s, usually self limiting, • Mins-hours: meniere’s (vertigo, SN deafness, tinnitus, aural fullness) • overdiagnosed so refer all suspected cases to ENT to confirm the diagnosis • >24h • peripheral lesion: trauma / viral labyrinthitis (URTI, sudden onset vertigo, n+v, prostration, hearing normal, TM normal). Rx = cyclizine/prochlorperazine • Central pathol: CVA/tumour/MS… • On neck extension and rotation in elderly: VB insuff

  32. Summary • We have covered: • infections of the ear: OE, furunculosis, HZV, OM and know when ABx are appropriate plus other measures which maybe required. • Understand which foreign bodies require urgent removal. • Understand the risks/complications of ear trauma and how lacerations/haematomas and bites should be managed. • Know how to assess/investigate deafness and understand that sudden deafness merits urgent ENT review. • Brief insight into the common DDx for tinnitus and vertigo.
