- pinna
- auricle (little ear) projected part of the external ear
- external auditory meatus
- external passage for sounds collected from the pinna to the tympanum
- cerumen
- waxy substance secreted by glands located throughout the external canal
- tympanic membrane
- eardrum; drum-like structure that receives sound collected in the external auditory meatus and amplifies it through the middle ear
- malleus
- hammer; first of the three auditory ossicles of the middle ear
- incus
- anvil; middle of the three auditory ossicles of the middle ear
- stapes
- stirrup; last of the three auditory ossicles of the middle ear
- eustachian tube
- tube connecting the middle ear to the pharynx
- mastoid process
- projection of the temporal bone located behind the ear containing air cells that connect to the middle ear
- oval window
- membrane that covers the openng between the middle ear and the 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
- labyrinth
- maze; inner ear consisting of bony and membranous labyrinths
- cochlea
- coiled tubular strcuture of the inner ear that contains the organ of Corti
- perilymph
- fluid that fills the bony labyrinth of the ear
- endolymph
- fluid within the cochleaer duct of the inner ear
- organ of Corti
- organ located in the cochlea that contains receptors that receive vibrations and generate nerve impulses for hearing
- vestibule
- middle part of the inner ear in front of the semicircular canals and behind the cochlea that contains the utricle and saccule
- utricle
- larger of two sacs within the membranous labyrinth of the vestibule in the inner ear
- saccule
- smaller of two sacs within the membranous labyrinth of the vestibule in the inner ear
- semicircuar canals
- three canals within the inner ear that contain specialized receptor cells that generate nerve impulses with body movement
-
otalgia
otodynia - earache
- otorrhagia
- bleeding from the ear
- otorrhea
- purulent drainage from the ear
- tinnitus
- a jingling; ringing or buzzing in the ear
- vertigo
- a turning round; dizziness
- otitis externa
- inflammation of the external auditory meatus

-
myringitis
tympanitis - inflammation of the eardrum
- otitis media
- inflammation of the middle ear
- aerotitis media
- inflammation of the middle ear from changes in atmostpheric pressure; often occurs in frequent air travel
- otosclerosis
- hardening of the bony tissue in the ear
- mastoiditis
- inflammation of the mastoid process; most commonly seen as a result of the spread of inflammation and infection in otitis media
- eustachian obstruction
- block of the eustachian tube usually as a result of infection, as in otitis media
- acousitc neuroma
- benign tumor on the auditory nerve (8th cranial nerve) that causes vertigo, tinnitus, and hearing loss
- aplasia
- condition of absence of malformation of inner ear structures during embryonic development, resulting in hearing loss
- labyrinthitis
- inflammation of the labyrinth
- Meniere disease
- disorder of the inner ear due to an excessive buildup of endolymphatic fluid causing episodes of vertigo, tinnitus, nausea, vomiting, and hearing loss; one or both ears can be affected, and attacks vary in frequency and intensity
- deafness
- genereal term for partial or complete hearing loss
- conductive hearing loss
- hearing impairment caused by intereference with sound or vibratory energy in the external canal, middle ear, or ossicles
- sensorineural hearing loss
- hearing impairment caused by lesions or dysfunction of te cochlea or auditory nerve
- mixed hearing loss
- combination of sensorineural and conductive hearing loss
-
presbyacusis
presbycusis - hearing impairment of old age
- audiometry
- process of measuring hearing
- audiometer
- instrument to measure hearing
- audiogram
- record of hearing measurement
- audiologist
- person 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, fork-like instrument that vibrates when stuck; used to test for hearing, especially bone conduction
- otoscopy
- use of an otoscope to examine the external auditory meatus (canal) and tympanic membrane
- pneumatic otoscopy
- otoscopic observation of the tympanic membrane as air is released into the external auditory meatus; immobility indictes the presence of middle ear effusion as occurs as a result of otitis media
- tympanometry
- measurement of the compliance and mobility of the tympanic membrane and ossicles of the middle ear by monitoring the response after exposure to external airflow pressure
- microsurgery
- surger with the use of a microscope used in procedures involving delicate tissue such as the ear
-
myringotomy
tympanostomy - incision into the eardrum most often for insertion of a small metal or plastic tube to keep the meatus open avoiding fliud builup as that which occurs as a result of otitis media
- otoplasty
- surgical repair of the external ear
- stapedectomy
- excision of the stapes to correct ososclerosis
- tympanoplasty
- vein graft of a scarred tympanic membrane to improve sound conduction
- auditory prosthesis
- any internal or external device that improves or substitues for natural hearing
- hearing aid
- external amplifying device designed to improve hearing by more effective collection of sound into the ear
- cochlear implant
- electronic device implaned in the cochlea that provides sound preceptio to patients with severe or profound sensorineural hearing loss in both eyes
