A Bulging Tympanic Membrane
With Impaired Mobility is
Diagnostic of Acute Otitis Media
Middle Ear Effusion is
Demonstrated Here by The
Presence of Bubbles. An Effusion
Must Be Present to Diagnose Acute
Otitis Media or Otitis Media With
Effusion
A Tympanic Membrane That Is
Restricted as The One Shown Here,
May Be Painful; However, It Is
Unlikely to Be Caused By a
Bacterial Infection
