EAR EXAMINATION WITH AN OTOSCOPE
When examining with an Otoscope, one may note
1) The Otoscope should be held like a pen.
2) The Otoscope should be held in the hand which side the ear is to be examined i.e. RIGHT for RIGHT and LEFT for LEFT.
3) While examining, the Ring finger and the Little finger of the hand holding the scope should rest on the cheek of the patient to ensure that there is NO inadvertent trauma ( to the Ear).
4) The other hand pulls the pinna to ensure straightening of the pinna.
ADVANTAGE/S
1)Self contained source of illumination..
2) Magnification ..2X (some newer models have more.
3) Facility for Siegeization.
DISADVANTAGE/S
1)Runs on dry battery cells..hence illumination over a period of time will decrease.
2) Uniocular vision....hence compromise of DEPTH OF FIELD.
