-ACUSIS (ADDITIONAL SUFFIX)
hearing condition
EXTERNAL EAR - PINNA
auricle (little ear); projected part of the external ear (pinna = feather)
EXTERNAL EAR - EXTERNAL AUDITORY CANAL
external passage for sounds collected from the pinna to the tympanum
EXTERNAL EAR - CERUMEN
a waxy substance secreted by glands located throughout the external canal
MIDDLE EAR - TYMPANIC MEMBRANE (TM)
eardrum; drumlike structure that receives sound collected in the external auditory canal and amplifies it through the middle ear
MIDDLE EAR - MALLEUS
hammer; first of the three auditory ossicles of the middle ear
MIDDLE EAR - INCUS
anvil; middle of the three auditory ossicles of the middle ear
MIDDLE EAR - STAPES
stirrup; last of the three auditory ossicles of the middle ear
EUSTACHIAN TUBE
AUDITORY TUBE
tube connecting the middle ear to the pharynx (throat)
OVAL WINDOW
membrane that covers the opening between the middle ear and inner ear
INNER EAR
structures and liquids that relay sound waves to the auditory nerve fibers on a path to the brain for interpretation of sound
INNER EAR - LABYRINTH
maze; inner ear consisting of bony and membranous passages
INNER EAR - COCHLEA
coiled tubular structure of the inner ear that contains the organ of corti (cochlea = snail)
INNER EAR - PERILYMPH
fluid that fills the bony labyrinth of the inner ear
INNER EAR - ENDOLYMPH
fluid within the cochlear duct of the inner ear
ORGAN OF CORTI
organ located in the cochlea; contains receptors (hair cells) that receive vibrations and generate nerve impulses for hearing
VESTIBULE
middle part of the inner ear in front of the semilunar canals and behind the cochlea that contains the utricle and the saccule
UTRICLE
larger of two sacs within the membranous labyrinth of the vestibule in the inner ear (uter = leather bag)
SACCULE
smaller of two sacs within the membranous labyrinth of the vestibule in the inner ear (sacculus = small bag)
SEMICIRCULAR CANALS
three canals within the inner ear that contain specialized receptor cells that generate nerve impulses with body movement
ANACUSIS
total hearing loss
OTALGIA
OTODYNIA
earache
OTORRHAGIA
bleeding from the ear
OTORRHEA
purulent drainage from the ear
PARACUSIS
impaired hearing
TINNITUS
a jingling; ringing or buzzing in the ear
VERTIGO
a turning round; dizziness
OTITIS EXTERNA
inflammation of the external auditory canal
CERUMEN IMPACTION
excessive buildup of wax in ear, often reducing hearing acuity, especially in elderly persons
MYRINGITIS
TYMPANITIS
inflammation of the eardrum
OTITIS MEDIA
inflammation of the middle ear
AEROTITIS MEDIA
inflammation of the middle ear from changes in atmospheric pressure; often occurs in frequent air travel
EUSTACHIAN OBSTRUCTION
blockage of the eustachian tube usually as a result of infection, as in otitis media
LABYRINTHITIS
inflammation of the labyrinth (inner ear)
OTOSCLEROSIS
hardening of the bony tissue in the ear
DEAFNESS
general term for partial or complete hearing loss
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
PRESBYACUSIS
PRESBYCUSIS
hearing impairment in old age
AUDIOMETRY
process of measuring hearing
AUDIOMETER
instrument to measure hearing
AUDIOGRAM
record of hearing measurement
AUDIOLOGIST
the health professional who specializes in the study of hearing impairments
AUDITORY ACUITY TESTING
physical assessment of hearing; useful in differentiating between conductive and sensorineural hearing loss
TUNING FORK
two-pronged, forklike instrument that vibrates when struck; used to test hearing, especially bone conduction
OTOSCOPY
use of an otoscope to examine the external auditory canal and tympanic membrane
TYMPANOMETRY
measurement of the conductibility of the tympanic membrane and ossicles of the middle ear by monitoring the response to external airflow pressures
MICROSURGERY
surgery with the use of a microscope used in delicate tissue such as the ear
MYRINGOTOMY
incision into the eardrum, most often for insertion of a small polyethylene (PE) tube to keep the canal open and prevent fluid buildup, such as occurs in otitis media
OTOPLASTY
surgical repair of the external ear
STAPEDECTOMY
excision of the stapes to correct otosclerosis
TYMPANOPLASTY
vein graft of a scarred tympanic membrane to improve sound conduction
EAR LAVAGE
irrigation of the external ear canal, often to remove excessive buildup of cerumen
EAR INSTILLATION
introduction of a medicated solution into the external canal, usually administered by drop (gt) or drops (gtt) in the affected ear or ears:
AD auris dextra - right ear
AS auris sinistra - left ear
AU aures unitas - both ears
ANTIBIOTIC
drug that inhibits the growth of or destroys microorganisms; used to treat diseases caused by bacteria (e.g., otitis media)
ANTIHISTAMINE
drug that blocks the effects of histamine
HISTAMINE
a regulatory body substance released in allergic reactions, causing swelling and inflammation of tissues; seen in hay fever and urticaria (hives)
ANTI-INFLAMMATORY
a drug that reduces inflammation
DECONGESTANT
a drug that reduces congestion and swelling of membranes, such as those of the nose and eustachian tube in an infection
