  23. Conductive hearing disorder
    Affects the bone in the middle ear; sound waves are blocked as they move thru the auditory canal or middle ear and cant reach the inner ear. (cause by disease or malformation/damage to outer or inner ear).

    s/s: muffle or faint sound, may have earache or discharge.
  24. Sensorineural hearing disorder
    Sound waves are conducted normally, but the messages are not transmitted properly to the brain. (caused by head injuries, old age, loud noises, hereditary, etc.)

    s/s: sounds are muffled or distorted, high tones are inaudible, dizziness or nausea and ringing or buzzing noise.
  25. Central hearing disorders
    Sound signals are transmitted normally but interupted incorrectly by the brain (caused by damage or malfuction to the brain).

    s/s: communication difficulties, difficulty hearing speech in a noisy enviroment
  26. Ear irrigation
    temp is 98.6; aseptic technique unless tympanic membrane is damaged

    pt should lie on the affected side for 5 minutes (excess fluid should flow by gravity)

    • Tx: Antibiotics, antifungals, ear plugs
    • Prevention: Acetic Acid (Alcohol/Vingear solution)
  29. Fungal infections
    Occurs in warm, damp climates especially when auditory canal hasn't been completely dried; fungus grows

    Tx: ear drops, antifungal meds, alcohol and glycerin, long term treatment
  30. Perforated tympanic membrane
    caused by extremely loud noises, internal infection and increased pressure.

    Tx: depends on the amount of damage, heals spontaneously or myringotomy
  31. Serous otitis media
    Fluid collects in the middle ear as a result of obstruction of Eustachian Tube (infection, allergy, tumor or change in altititude)

    s/s: crackling sensation, fullness in ear or hearing loss

    Tx: myringotomy
  32. Acute purulent otitis media
    Pus collects in the tympanic membrane

    s/s: inflamed or bulging tympanic membrane, fever, HA, hearing impaired.

    Tx: myringotomy to prevent rupture of eardrum.
  33. Complications of purulent otits media
    • 1. otitis media
    • 2. mastoiditis
    • 3. meningitis
    • 4. brain abscess
  34. Chronic otitis media
    Associated with punctured ear drum or complications of acute otitis media.

    s/s: ringing of the ear, drainage, HA, N/V, pain, increased temp, chills and dizziness.

    Tx: antibiotics and mastoidectomy may be necessary
  35. Myringectomy
    A surgical incision is made into the tympanic membrane to drain the fluid from the ear and tubes are placed in the ear to drain excess fluid which releases pressure and pain.

    Post op: small cotton ball in ear (do not plug tightly), antibiotics, rest and adequate diet
  36. Polyethyline tubes (PE tubes)
    placed in eardrums and allows continuous drainage from the middle ear.

    post op: do not put water into ears.
  37. Tympanoplasty
    Reconstruction of the middle ear to preserve vital parts with less impairment of hearing (reconstruction of bones).

    done instead of radical mastoidectomy
  38. Otosclerosis
    bony fixations of stapes which interfers with vibrations of stapes.

    s/s: tinnitus, slow loss of hearing

    Tx: surgery (stapidectomy)
  39. Stapedectomy
    Stapes removed and replaced by a small piece of wire or plastic piston

    post op: watch for injury potential, do not blow nose violently, no water in ears, back to normal activity in 2 weeks.
  40. Mastoidectomy
    Removal of infected mastoid cells and to ensure drainage.

    (mastoid bone contains facial nerve and inner ear).
  41. Fenestration
    Constructing a new window to replace natural window that connects the middle ear to the inner ear so that vibrations can be carried.

    post op: instruct pt to move slowly (may have N/V), hearing takes 4-6 weeks to improve and avoid blowing nose.
  42. Meniere's syndrome
    Disturbance of semi-circular canals in the inner ear (cause is excess fluid).
