Normal Right Tympanic Membrane

Description : Note the "cone of Light" which is located on the anteroinferior quadrant of the tympanic membrane.

The cone of light is the only portion of the tympanic membrane that lies at right angles to the long axis of the external auditory canal and which therefore reflects the light of otoscope directly back towards the examiners eye.
