means pertaining to the sense of hearing
means relating to sound or hearing
the external portion of the ear; "auricle"
external auditory canal
transmits sound waves from the pinna to the tympanic membrane of the middle of the ear
secreted by ceruminous glands that line the auditory canal, "earwax"
located between outer ear and inner ear, transmits sound across this space
located between the outer and middle ear, "eardrum"
mastoid bone cells
hallow air spaces located in the mastoid process of the temporal bone
three small bones found in the middle ear
known as the hammer
narrow tubes that lead from the middle ear to the nasal cavity and the throat
contains the sensory receptors for hearing and balance
located under the base of the stapes, the membrane that separates the middle ear from inner ear
the snail-shaped, fluid filled structure that forms the inner ear
a fluid filled cavity within the cochlea that vibrates when sound waves strike it
organ of Corti
receives vibrations from the cochlear duct and relays them to the auditory nerve fibers
contains the liquid endolymph and sensitive hair-like cells
transmit this information to the brain, and the brain sends messages to muscles in all parts of the body to ensure that equilibrium is maintained
the process by which sound waves enter the ear through the pinna
occurs as the eardrum vibrates and moves the auditory ossicles
occurs when sound vibrations reach the inner ear
specializes in the measurement of hearing function and in the rehabilitation of persons with hearing impairments
an accumulation of earwax that forms a solid mass by adhering to the walls of the external auditory canal
pain in the ear; "earache"
any inflammation of the ear
a fungal infection of the external auditory canal; "swimmer's ear"
the flow of pus from the ear
bleeding from the ear
pressure-related ear discomfort that can be caused by pressure changes when flying, driving in the mountains, scuba diving, or when the eustachian tube is blocked
inflammation of the eustachian tube
an inflammation of any part of the mastoid bone cells
a contagious inflammation that causes painful blisters on the eardrum
the ankylosis of the bones of the middle ear, resulting in a conductive hearing loss
patulous eustachian tube
dissension of the eustachian tube
an inflammation of the middle ear
acute otitis media
usually associated with an upper respiratory infection and is most commonly seen in young children
serous otitis media
a fluid buildup in the middle ear that can follow acute otitis media or can be caused by obstruction of the eustachian tube
acute purulent otitis media
a buildup of pus within the middle ear due to infection
an inflammation of the labyrinth that can result in vertigo and deafness
a sense of whirling, dizziness, and the loss of balance, that is often combined with nausea and vomiting
a rare chronic disease in which the amount of fluid in the inner ear increases intermittently, producing attacks of vertigo, a fluctuating hearing loss, and tinnitus
a ringing, buzzing, or roaring sound in one or both ears
the complete or partial loss of the ability to hear
a gradual loss of sensorineural hearing that occurs as the body ages
conductive hearing loss
occurs when the sound waves are prevented from passing from the air to the fluid filled inner ear
sensorineural hearing loss
develops when the auditory nerve or hair cells in the inner ear are damaged
noise-induced hearing loss
a type of nerve deafness caused by repeated exposure to extremely loud noises such as a gunshot, or to moderately loud noise that continues for long periods of time
the measurement of the ability to hear and understand speech sounds based on their pitch and loudness
the use of an audiometer to measure hearing acuity
a measure of sound frequency that determines how high or low a pitch is
commonly used as the measurement of the loudness of sound
involves testing with one ear
involves testing with both ears
the use of air pressure in the ear canal to test for disorders of the middle ear
the surgical repair of the pinna of the ear
the surgical removal of mastoid cells
the surgical incision in the eardrum to create an opening for the placement of tympanostomy tubes
tiny ventilating tubes placed through the eardrum to provide ongoing drainage for fluids and to relieve pressure that can build up after childhood ear infections; "pediatric ear tubes"
the surgical correction of a damaged middle ear, either to cure chronic inflammation of to restore function
the surgical removal of the top portion of the stapes bone and the insertion of a small prosthetic device known as a piston that conducts sound vibrations to the inner ear
a surgical procedure in which a new opening is created in the labyrinth to restore hearing
an external electronic device that uses a microphone to detect sounds
the surgical removal of all or a portion of the labyrinth
a surgical incision between two of the fluid chambers of the labyrinth to allow the pressure to equalize
an implanted electronic device that can give a deaf person a useful auditory understanding of the environment and/or hearing and help them to understand speech
