Evaluation of Ear with a Otoscope 

 

 

The otoscopic exam is performed by gently pulling the auricle upward and backward. 

In children, the auricle should be pulled downward and backward. This process will 

move the acoustic meatus in line with the canal. Hold the otoscope like a pen/pencil 

and use the little finger area as a fulcrum. This prevents injury should the patient turn 

suddenly.  

 

Inspect the external auditory canal.  

 

Evaluate tympanic membrane  

o

 

Note the color (red, white, yellow) and translucency (transparent, 

opaque) and position (retracted, neutral or bulging) of the drum
