Mastoiditis (ReelDx)
ReelDx Virtual Rounds (Mastoiditis )
Patient will present as → a 10-year-old boy with otalgia, worsening over the last 5-days and associated with nasal congestion. The patient is afebrile with a temperature of 98 ° F. Examination reveals edema of the external auditory canal producing an anterior and inferior displacement of the auricle with percussion tenderness posteriorly. 

A complication of acute otitis media. Fever, otalgia, pain & erythema posterior to the ear, and forward displacement of the external ear

  • Organisms: S. pneumoniae, H. influenzae, M. catarrhalis, S. aureus, S. pyogenes

DX: clinical; CT scan temporal bone with contrast for complicated/toxic appearing

TX: IV antibiotics (ceftriaxone), drainage of middle ear fluid

Meniere disease
ReelDx Virtual Rounds (Foreign body in ear)
Patient will present as → 41 yo female presents with intermittent episodes of vertigo, tinnitus, nausea, and hearing loss over the past week.

Vertigo attacks lasting hours, classic triad of low-frequency hearing loss, tinnitus with aural (ear) fullness, and episodic vertigo

"Meniere's disease is associated with EPISODIC vertigo and NOT associated with viral infections. This differentiates it from Labyrinthitis which is associated with CONTINUOUS vertigo along with hearing loss +/- tinnitus and is usually associated with an upper respiratory infection."

DX: Although audiometric testing is a required part of the diagnostic evaluation, there is no specific diagnostic test for MD

  • Imaging ( MRI with gadolinium enhancement), although not required for the diagnosis of MD, is frequently performed to exclude important disorders that can present with similar symptoms.

A clinical diagnosis of MD is made based upon the following criteria:

  • Two or more spontaneous episodes of vertigo, each lasting 20 minutes to 12 hours
  • Audiometrically documented low- to mid-frequency sensorineural hearing loss in the affected ear
  • Fluctuating aural symptoms (reduced or distorted hearing, tinnitus, or fullness) in the affected ear
  • Symptoms not better accounted for by another vestibular diagnosis

TX: Low salt diet, diuretics (HCTZ + triamterene) to reduce aural pressure

Patient will present as→ a 70-year-old female who states that her children and grandchildren have asked her to seek medical attention as she seems to be losing her hearing.  She also describes an occasional ringing, buzzing, and hissing sound. She is in generally good health and her only medications are a multivitamin along with calcium and vitamin D. You examine her ears and find the external auditory canals to be free of cerumen and the tympanic membranes to be normal in appearance.

A perceived sensation of sound in the absence of an external acoustic stimulus; often described as a ringing, hissing, buzzing, or whooshing.

  • 90% are associated with sensorineural hearing loss – caused by loud noise, presbycusis, medications (aspirin, antibiotics, aminoglycosides, loop diuretics, and CCBs), Meniere's disease, acoustic neuroma

DX: All patients with significant tinnitus should be referred for comprehensive audiologic evaluation to determine the presence, degree, and type of hearing loss.

  • In patients with unilateral tinnitus and hearing loss, acoustic neuroma should be ruled out by gadolinium-enhanced MRI
  • In patients with unilateral tinnitus and normal hearing and physical examination, MRI is not necessary unless tinnitus persists > 6 mo

TX: No pharmacologic agent has been shown to cure or consistently alleviate tinnitus

  • The goal is to try to identify the cause, i.e remove ototoxic medications, hearing aids
