Otoscope or auriscope:
is a medical device which is used to look into
the ears.
Introduction
This is performed in order to examine the ear canal that leads
from the outer ear (pinna) to the eardrum.

Otorhinolaryngology:
The word otorhinolaryngology or its shorter form,
otolaryngology
, is
derived from the Greek root words: otos (ear), rhino (nose), laryngo
(windpipe) and logos (science).Ear, Nose, Throat (ENT).
Also it is a surgical subspecialty within medicine that deals with the
surgical and medical management of conditions of the head and neck.

Examination of the tympanic membrane and middle ear by
otoscopic examination can help providers diagnose a wide variety
of conditions, including:
Clinical Significance (Usage)
It is a painful type of ear infection. It occurs when the area behind
the eardrum, the middle ear becomes inflamed and infected.
1. Acute otitis media
Figure 6: cross-section of the ear shows the acute otitis media

2. Traumatic perforation (ruptured) of the tympanic membrane
This ruptured causes sudden severe pain sometimes followed
by bleeding from the ear, hearing loss, and tinnitus.

3. Cholesteatoma
It is an abnormal growth of skin within the middle ear. It
begins in the middle ear and may spread to the mastoid bone
behind the ear.
