  1. auricle
    little ear; projected part of the external ear.
  2. external auditory meatus
    external passage for sounds collected from the pinna to the tympanum
  3. cerumen
    waxy substsances secreted by glands located throughout the external canal
  4. tympanic membrane
    eardrum; drug-like structure that receives sound collected in the external auditory meatus and amplifies it through the middle ear.
  5. eustachian tubes
    tube connecting the middle ear to the pharynx
  6. mastoid process
    projection of the temporal bone located behind the ear containing air cells that connect to the middle ear.
  7. labyrinth
    maze; inner ear consisting of bony and membranous labyrinths
  8. cochlea
    coiled tubular structure of the inner ear that contains the organ of Corti
  9. vestibule
    middle part of the inner ear in front of the semicircular canals and behind the cochlea that contains the utricle and saccule
  10. semicircular canals
    three canals within the inner ear that contain specialized receptor cells that generate nerve impulses with body movement
  11. aplasia
    condition of absence or malformation of inner ear structures during embryonic development, resulting in hearing loss
  12. otalgia
  13. otorrhagia
    bleeding form the ear
  14. otorrhea
    purulent drainage from the ear
  15. tinnitus
    a jingling; ringing or buzzing in the ear
  16. vertigo
    a turning around; dizziness
  17. otitis externa
    inflammation of the external auditory meatus
  18. tympanitis
    inflammation of the eardrum
  19. otitis media
    inflammation of the middle ear
  20. otosclerosis
    hardening of the bony tissue in the ear
  21. mastoiditis
    inflammation of the mastoid process; most commonly seen as a result of the spread of inflammation and infection in otitis media
  22. acoustic neuroma
    benign tumor on the auditory nerve that causes vertigo, tinnitus, and hearing loss
  23. 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
  24. conductive hearing loss
    hearing impairment caused by interference with sound or vibratory energy in the external canal, middle ear, or ossicles
  25. sensorineural hearing loss
    hearing impairment caused by lesions or dysfunction of the cochlea or auditory nerve
  26. audiologist
    person who specializes in the study of hearing impairments
  27. otoscopy
    use of an otoscope to examine the external auditory meatus (canal) and tympanic membrae.
  28. tympanostomy
    incision into the eardrum, most often for insertion of a small metal or plastic tube to keep the meatus open, avoiding fluid buildup as that which occurs as a result of otitis media.
  29. cochlear implant
    electronic device implanted in the cochlea that provides sound perception to patients with severe or profound sensorineural hearing loss in both ears
