This page provides all possible meanings and translations of the word otoscope
otoscope, auriscope, auroscope(noun)
medical instrument consisting of a magnifying lens and light; used for examining the external ear (the auditory meatus and especially the tympanic membrane)
An instrument used for examining the eardrum and interior of the outer ear.
An Otoscope or auriscope is a medical device which is used to look into the ears. Health care providers use otoscopes to screen for illness during regular check-ups and also to investigate when a symptom involves the ears. With an otoscope, it is possible to see the outer ear and middle ear. Otoscopes consist of a handle and a head. The head contains a light source and a simple low-power magnifying lens, typically around 8 diopters. The distal end of the otoscope has an attachment for disposable plastic ear specula. The examiner first straightens the ear canal by pulling on the pinna and then inserts the ear speculum side of the otoscope into the external ear. It is important to brace the hand holding the otoscope against the patient's head to avoid injury to the ear canal by placing the index finger or little finger against the head. The examiner can then look through a lens on the rear of the instrument and see inside the ear canal. In many models, the lens can be removed, which allows the examiner to insert instruments through the otoscope into the ear canal, such as for removing earwax. Most models also have an insertion point for a bulb capable of pushing air through the speculum which is called pneumatic otoscope. This puff of air allows an examiner to test the mobility of the tympanic membrane.
