    2. Observation Protocol for Acute Otitis Media Management
    3. Otitis Media Acute Treatment
  2. Symptoms (reference to Incidence in Otitis Media cases)
    1. Ear Pain (Otalgia) (40-60%)
      1. Predicts <50% of Otitis Media
      2. Predicts 80% of Otitis Media in presence of URI
      3. Only 12% of children "pulling ear" have Otitis Media
      4. Other causes of Otalgia
        1. Upper Respiratory Infection
        2. Cerumen Impaction
        3. Sterile effusion
    2. Rhinitis (90%)
    3. Cough (78%)
    4. Constitutional symptoms (60-80%)
      1. Ill Child
      2. Poor appetite
      3. Irritable
    5. Low-grade fever (22-69%)
      1. Temperature under 101 degrees for <24 hours
    6. Difficult sleeping in infants (35-50%)
    7. Ear Drainage (5%)
      1. Liquefied cerumen from fever or
      2. Pus from perforated Tympanic Membrane
    8. Unilateral Hearing Loss
    9. Upper Respiratory Infection
      1. Incidence of Otitis Media after 5 days of URI: 40%
  3. Signs: Tympanic Membrane Findings by Otoscopy
    1. Color
      1. Cloudy, opacified Tympanic Membrane
        1. Positive Predictive Value: 80%
      2. Red Tympanic Membrane
        1. Multiple causes (Nonspecific finding)
          1. Crying
          2. Viral illness
        2. Positive Predictive Value
          1. Distinctly Red Tympanic Membrane: 65%
          2. Slightly Red Tympanic Membrane: 16%
    2. Position
      1. Tympanic Membrane bulging
        1. Positive Predictive Value: 89%
        2. First occurs in posterosuperior quadrant
        3. TM most compliant in posterosuperior quadrant
      2. Loss of landmarks (Cannot see Umbo) (80% PPV)
      3. Light reflex may be absent from bulging TM
    3. Mobility
      1. TM Immobile by Pneumatic Otoscopy
        1. Positive Predictive Value: 78%
      2. Tympanometry
        1. Normal Tympanogram
          1. No Acute Otitis Media
        2. Middle Ear effusion
          1. Test Sensitivity: 90%
          2. Test Specificity: 80%
          3. Negative Predictive Value: 77%
        3. Precaution
          1. Only Otoscopy can distinguish Acute Otitis Media (AOM) from Otitis Media with Effusion (OME)
