The outer ear lies in a recess which can be closed tightly by a dorsal flap of skin.
While in place, the tubes keep the incision from closing, forming an open channel between the middle ear and the outer ear.
Tympanic membrane-The eardrum, a thin disc of tissue that separates the outer ear from the middle ear.
A perforated eardrum (tympanum perforation) is an opening or rupture in the eardrum (tympanic membrane), the thin membrane that separates the outer ear canal from the middle ear.
The eardrum (tympanic membrane) is a thin, semi-transparent membranous wall that stretches across the ear canal and separates the outer ear from the middle ear.
Although earwax, produced by glands in the outer ear canal, normally works its way out of the ear, sometimes excessive amounts build-up and harden in the outer ear canal, gradually impairing hearing.
The outer ear should be cleaned wiped with a clean washcloth.
Impaction-A condition in which earwax has become tightly packed in the outer ear to the point that the external ear canal is blocked.
Deep within the outer ear canal is the eardrum, which is a thin, transparent membrane that vibrates in response to sound.
