  1. Approach to Ear Problems By Stacey Singer-Leshinsky R-PAC

  2. Includes: • Disease of the external ear • Disease of the middle ear • Disease of the inner ear

  3. Normal TM

  4. External Auditory CanalOtitis Externa • Defenses include cerumen which acidifies the canal and suppresses bacterial growth.

  5. External Auditory CanalOtitis Externa • Cerumen prevents water from remaining in canal and causing maceration. • Etiology: Pseudomonas aeruginosa and staphylococcus aureus, strep

  6. External Auditory CanalOtitis Externa • Risk factors for Otitis Externa include: • Swimming, perspiration, high humidity, insertion of foreign objects, • Eczema, psoriasis, seborrheic dermatitis

  7. External Auditory CanalOtitis Externa-Clinical manifestations • Otalgia/otorrhea • Fever • Pain • Canal edematous and obscured with debris, discharge, blood, or inflammation • Lymphadenopathy

  8. External Auditory CanalOtitis Externa- • Complications • malignant otitis externa caused by pseudomonas • Differential diagnosis • basal cell carcinoma • squamous cell carcinoma

  9. External Auditory CanalOtitis Externa-Management • Topical antibacterial drops such as Neomycin otic, polymyxin, Quinolone otic • Otic steroid drops containing polymyxin-neomycin and a topical corticosteroid. • Analgesics

  10. External Auditory CanalOtitis Externa-Management • Discuss patient education issues such as: • Swimmer prophylaxis contains acid and alcohol

  11. External Auditory CanalChronic Otitis Externa • Duration of infection greater than four weeks, or greater than 4 episodes a year • Risks: inadequate treatment of otitis externa, persistent trauma, inflammation or malignant otitis externa. • Etiology: Bacterial,fungal or dermatologic such as candida or Aspergillus, pseudomonas or psoriasis

  12. External Auditory Canal Chronic Otitis Externa • Purulent discharge • Dry or scaly. • Pruritus • Conductive hearing loss • Diagnosis:

  13. External Auditory CanalChronic otitis externa-Management • Cover fungi with clotrimazole(Lotrimin) • Systemic antifungal include ketoconazole • Cortisporin • Wick with few drops of Domeboro’s astringent • Differential diagnosis to include basal cell or squamous cell carcinoma, Foreign bodies, otitis media

  14. External Auditory CanalMalignant Otitis Externa • Inflammation and damage of the bones and cartilage of the base of the skull • Occurs primarily in immunocompromised • Most common etiology is pseudomonas aeruginosa.

  15. External Auditory CanalMalignant Otitis Externa • Otorrhea: yellow green, foul smelling. • Granulation tissue in external auditory canal • Trismus • Fever • Facial and cranial nerve palsies

  16. External Auditory CanalMalignant Otitis Externa • Diagnosis: Culture of ear secretions and pathological examination of granulation tissue, CT • Complications include sepsis, cranial nerve palsies, meningitis, brain abscess, osteomyelitis of the temporal bone and skull • Differential diagnosis to include basal cell or squamous cell carcinoma

  17. External Auditory CanalMalignant Otitis Externa • Need IV antibiotics • Might need surgical debridement. • If treatment interrupted rate of recurrence is 100%

  18. External Auditory CanalCerumen Impaction • Cerumen is produced by apocrine and sebaceous glands in external ear canal. • Often caused by attempts to clean the ear, or water in canal • Cerumen is pushed down

  19. Cerumen ImpactionClinical Manifestations • Hearing loss • Stuffed or full feeling to ear • Pain if cerumen touches TM

  20. External Auditory CanalCerumen Impaction • Be sure TM is intact prior to lavage • Irrigate ear with one part peroxide, and one part water • Debrox and Cerumenex drops • Ear irrigation and manual cerumen removal

  21. External Auditory CanalForeign body • Can include toys, beads, nails, vegetables or insects. • Damage depends on amount of time object has been in ear.

  22. External Auditory CanalForeign body-Clinical Manifestations • Might present with purulent discharge • Pain • Bleeding • Hearing loss

  23. External Auditory CanalForeign body • Complications include internal injury • Differential diagnosis to include cholesteatoma, cerumen impaction, otitis externa

  24. External Auditory CanalForeign body- Management • Irrigation is best provided the TM is not perforated • Destroy insect with lidocaine or mineral oil. • Irrigate and suction liquid. • For inanimate objects suction or use alligator forceps.

  25. Tympanic MembraneBullous Myringitis • Vesicles develop on the TM second to viral infections or bacterial infection • Usually associated with middle-ear infection • May extend into canal.

  26. Tympanic MembraneBullous Myringitis- Clinical Manifestations • Sudden onset of severe pain • No fever usually • No hearing impairment • Bloody otorrhea possible • Inflammation to TM • Multiple reddened inflamed blebs possibly blood filled

  27. Tympanic Membrane Bullous Myringitis • Differential diagnosis to include squamous or basal cell carcinoma, acute otitis media • Complications

  28. Tympanic Membrane Bullous Myringitis-Management • Antibiotics • If pain is severe, rupture the vesicles with a myringotomy knife • Analgesics

  29. Tympanic MembranePerforated TM • Etiology is direct trauma, infection, pressure build up • Bacteria can travel into middle ear and lead to secondary infection

  30. Tympanic MembranePerforated TM- Clinical Manifestations • Sudden severe pain • Hearing loss • Drainage • Otoscope exam reveals puncture in TM, might be able to see bones of middle ear • Purulent otorrhea may begin in 24-48 hours post perforation

  31. Tympanic MembranePerforated TM • Differential diagnosis to include acute and chronic otitis media • Complications include secondary infection into inner ear

  32. Tympanic MembranePerforated TM-Management • Antibiotics to prevent infection or treat existing infection • Surgical repair

  33. Middle EarAcute Otitis Media • Viral respiratory infections cause inflammation of ET • When ET is blocked, fluid collects in the middle ear.

  34. Middle EarAcute Otitis Media • Common in fall, winter or spring • ET in child is shorter and more horizontal in infants/children. • Bacterial Etiology : S.pneumoniae, H.influenzae, and M.Catarrhalis. • Risks include URI,smoking at home, allergies, cleft palate, adenoid hypertrophy, bottle feeding, barotrauma

  35. Middle EarAcute Otitis Media • Otalgia. • Conductive hearing loss • URI symptoms • Vomiting, diarrhea • Fever • TM bulging and erythematous with decreased or poor light reflex. • Decreased TM mobility on pneumatic insufflation

  36. Middle EarAcute Otitis Media -Diagnosis • Tympanometry • Differential diagnosis to include TM perforation, Tympanosclerosis, recurrent AOM, mastoiditis

  37. Middle EarAcute Otitis Media -Management • Analgesics/ Antipyretics • Auralgan • Antibiotics • Trimethoprim-sulfamethoxazole or Azithromycin • Decongestants: • Avoid antihistamines

  38. Middle EarAcute Otitis Media –Patient Education • Myringotomy in patients with hearing loss, poor response to therapy or intractable pain • Discuss patient education issues including breast feeding, no smoking in homes, pneumococcal vaccine

  39. Middle EarAcute Otitis Media -Complications • TM perforation/ Tympanosclerosis • Recurrent AOM or chronic OM • Persistent middle ear effusion • Mastoiditis • Bacteremia

  40. Middle EarAcute Otitis Media -Recurrent OM • Three episodes of AOM in 6 months or 4 episodes in 12 months • Diagnosis • Prevent by antibiotic prophylaxis, pneumovax, tympanostomy tubes, adenoidectomy

  41. Middle EarOtitis Media with Effusion • Fluid accumulation behind TM in middle ear • Build up of negative pressure and fluid in eustachian tube • Common in children because of anatomy, cleft palate, allergies, barotrauma.

  42. Middle EarOtitis Media with Effusion • Hearing loss • Fullness, pressure • TM neutral or retracted. Gray or pink. • Landmarks visible or dull. • Decreased TM mobility

  43. Middle EarOtitis Media with EffusionDiagnosis • Tympanometry- most accurate, • Audiometry- • Differentials to include: Acute Otitis Media, malignant tumors to nasal cavity, cystic fibrosis

  44. Middle EarOtitis Media with Effusion Management • Decongestants/Oral steroids • Antibiotics • Myringotomy with or without tubes • Adenoidectomy • Complications:

  45. Middle EarChronic Otitis Media • Recurrent or persistent otitis media due to dysfunctional eustachian tube • Risks: allergies, multiple infections, ear trauma, swelling to adenoids. • Bacteria: P aeruginosa, proteus species, Staphylococcus aureus, and mixed anaerobic infections.

  46. Middle EarChronic Otitis Media • Causes long term damage to middle ear due to infection and inflammation including • Severe retraction of TM due to prolonged negative pressure • Scaring or erosion of small conducting bones of middle ear and inner ear • Erosion of mastoid • Thickening of mucous secretions in ET • Cholesteatoma • Persistent OME

  47. Middle EarChronic Otitis Media • Ear pain • Fullness to ears • Purulent discharge • Hearing loss • Dullness, redness or air bubbles behind TM

  48. Middle EarChronic Otitis Media • Diagnosis: clinical, audiometry, tympanometry, CT, MRI • Differential diagnosis to include AOM, cholesteatoma • Complications include bony destruction or sclerosis of mastoid air cells, facial paralysis, sensineural hearing loss, vertigo

  49. Middle EarChronic Otitis Media-Management • Antibiotics , steroids, placement of tubes. • Myringotomy • Surgical tympanoplasty, mastoidectomy

  50. Cholesteatoma • Epithelial cyst consists of desquamating layers of scaly or keratinized skin. • Erosion of ossicles common. As more material is shed, the cyst expands eroding surrounding tissue. • Two types: congenital and acquired. • Acquired due to tear in ear drum, infection
