When evaluating for possible otitis media, which of the following is of the LEAST diagnostic value?
A. History of a new onset of ear pulling starting several days after URIB. Presence of the light reflex
C. Translucency of the tympanic membrane (TM)
D. Mobility in response to pneumatoscopy
Answer. B. Presence of the light reflex
The light reflex
can often be visualized in an abnormal ear. Gauging decreased translucency of
the TM and evaluating for the presence of a fluid level behind the TM requires
experience, but these are good indicators of infection when detected. Mobility
in response to pneumatoscopy is also quite sensitive in practiced hands.
New-onset ear pulling after URI is frequently associated with otitis media.
