projected part of the external ear
external auditory meatus
external passage for sounds collected from the pinna to the tympanum
waxy substance secreted by glands located throughout the external canal
eardrum; drum-like structure that receives sounds collected in the external auditory meatus and amplifies it through the middle ear
tube connected the middle ear to the pharynx
projection of the temporal bone located behind the ear containing air cells that connect to the middle ear
maze; inner ear consisting of bony and membranous labyrinths
coiled tubular structure of the inner ear that contains the organ of Corti
bleeding from the ear
purulent drainage from the ear
a jingling, ringing or buzzing in the ear
a turning round; dizziness
inflammation of the external auditory meatus
inflammation of the eardrum
inflammation of the middle ear
hardening of the bony tissues in the ear
inflammation of the mastoid process; most commonly seen as a result of the spread of inflammation and infection in otitis media
benign tumor on the auditory nerve that causes vertigo, tinnitus, and hearing loss
disorder of the inner ear due to an excess buildup of endolymphatic causing episodes of vertigo, tinnitus, nausea, vomiting, and hearing; one or both ears can be affected, and attacks vary in frequency and intensity
conductive hearing loss
hearing impairment caused by interference with sound or vibratory energy in the external canal, middle ear, or ossicles
sensorineural hearing loss
hearing impairment caused by lesions or dysfunction of the cochlea or auditory nerve
person who specializes in the study of hearing impairments
use of an otoscope to examine the external acoustic meatus and tympanic membrane
incision into the eardrum, most often for the insertion of a small metal or plastic tube, to keep meatus open, avoiding fluid buildup as that which occurs as a result of otitis media
electronic device implanted in the cochlea that provides sound perception to patients with severe or profound sensorineural hearing loss in both ears
middle part of the inner ear in front of the semicircular canals and behind the cochlea that contains the utricle and saccule
