auditory
Pertaining to the sense of hearing
aural
pertaining to the ear
auricle
External portion of the ear; also known as the pinna
binaural
Pertaining to both ears
cholesteatoma
Tumor-like mass filled with epithelial cells and cholesterol
deafness
Complete or partial loss of the ability to hear. Hearing impairment is often used to describe a minimal loss of hearing as compared to the use of the word deafness when there is complete or extensive loss of hearing.
electrocochleography
Recording of the electrical activity produced when the cochlea is stimulated
endaural
Pertaining to within the ear
endolymph
Clear fluid contained within the labyrinth of the ear
equilibrium
State of balance
fenestration
Surgical operation in which a new opening is made in the labyrinth of the inner ear to restore hearing
labyrinth
The inner ear; made up of the vestibule, cochlea, and semicircular canals
labyrinthectomy
Surgical excision of the labyrinth
labyrinthitis
Inflammation of the labyrinth
labyrinthotomy
incision of the labyrinth
malleus
Largest of the three ossicles; also called the hammer
mastoiditis
Inflammation of one of the mastoid bones; characterized by fever, headache, and malaise
meunière disease
n abnormality of the inner ear causing a host of symptoms, including vertigo (sensation of spinning), tinnitus (a ringing or roaring sound in the ears), fluctuating hearing loss, and the sensation of pressure or pain in the affected ear. Symptoms are associated with a change in fluid volume within the labyrinth and can occur suddenly and arise daily or as infrequently as once a year.
monaural
pertaining to one ear
myringectomy
Surgical excision of the tympanic membrane
myringoplasty
Surgical repair of the tympanic membrane
myringoscope
Medical instrument used to examine the eardrum
myringotome
Surgical instrument used for cutting the eardrum
myringotomy
Surgical incision of the tympanic membrane to remove unwanted fluids from the ear
otalgia
Pain in the ear, earache
otic
pertaining to the ear
otitis
inflammation of the ear
otitis media
Inflammation of the middle ear. Most middle ear infections are a result of an upper respiratory infection (URI) that has spread through the eustachian tube
otolaryngologist
Physician who specializes in the study of the ear and larynx (voice box)
otolaryngology
Study of the ear and larynx (voice box)
otolith
ear stones
otomycosis
Fungal infection of the ear
otoneurology
Specialized diagnosis and treatment of the ear and its neurological association
otopharyngeal
Pertaining to the ear and pharynx
otoplasty
Surgical repair of the ear
otopyorrhea
pus in the ear
otorhinolaryngology
Study of the ear, nose, and larynx (voice box). The medical specialty is often referred to as ENT (ear, nose, throat); in this case, throat is used in a broad sense instead of larynx.
otosclerosis
Hardening (stiffening) condition of the ear structures characterized by progressive deafness
otoscope
Medical instrument used to examine the ear.
perilymph
Serum fluid of the inner ear
presbycusis
Impairment of hearing that occurs with aging
stapedectomy
Surgical excision of the stapes in the middle ear to improve hearing, especially in cases of otosclerosis. The stapes is replaced by a prosthesis.
tinnitus
The sensation of ringing or roaring sounds in one or both ears is a symptom associated with damage to the auditory cells in the inner ear. It can also be a symptom of other health problems.
tuning fork
nstrument used medically in a hearing test, which, when struck at the forked end, vibrates, producing a musical tone, and thus can be heard and felt. A metal instrument with a handle and two prongs or tines, tuning forks can be made of steel, aluminum, or magnesium alloy.
tympanectomy
Surgical excision of the tympanic membrane (eardrum)
tympanic
Pertaining to the eardrum (tympanic membrane)
tympanitis
Inflammation of the eardrum (tympanic membrane)
tympanoplasty
Surgical repair of the tympanic membrane (eardrum)
vertigo
Sensation of instability and loss of equilibrium; patients feel like they are spinning in space or objects around them are spinning. Caused by a disturbance in the semicircular canal of the inner ear or the vestibular nuclei of the brainstem.
