Revision of stapedectomy or Stapedotomy6966290
  1. History (in addition to hearing loss, list all appropriate)
    1. Hearing loss – age of onset, duration, progression, and disability. Also see tests.
    2. Otosclerosis in opposite ear – not suspected, suspected or confirmed.
    3. Family history of otosclerosis – none, suspected, confirmed.
    4. Tinnitus – present or absent. Describe severity and frequency.
    5. Vertigo – present or absent. Severity and frequency.
    6. Prior stapedectomy – outcome for hearing, post-op vertigo?
  2. Physical Examination (all required)
    1. Absence of acute or chronic infection.
    2. Description of both ear canals and tympanic membranes (the tympanic membrane should be intact on the side scheduled for surgery).
  3. Tests (all required)
    1. Audiometry
      • Pure Tone Average – air 25 dB or greater
      • Pure Tone – bone – 10-15 dB air bone gap of 0.5 – 2kH. May add 10 dB at 2.0 kH to allow for effect of Carhart notch. In case of profound loss and bone testing not valid, provide rationale for suspecting otosclerosis.
      • Speech and discrimination of both ears
    2. Tuning fork – 512 cps Weber and Rinne lateralization to ear for proposed surgery and reversal of Rinne (Bone > Air) strongly support diagnosis and decision to operate at lower Air/Bone gap.
    3. * Tympanogram and Acoustic Reflex – normal pressure and absent reflex support diagnosis.
      *Guideline Reviewers generally placed more confidence in 512 tuning fork than tympanometry

Postoperative Observations

  1. Vertigo–notify surgeon if unresponsive to medication. Severe symptoms could justify decision to keep patient overnight.
  2. Bleeding–reinforce dressing.
  3. Facial weakness on side of surgery.
  4. Emesis

Outcome Review

  1. One Week
    1. Healing–Are there signs of infection such as discharge, pain or swelling?
    2. Inner ear–Are there signs of inner ear reaction such as vertigo?
    3. Untoward reaction to any medications
  2. Beyond One Month
    1. Hearing–document with audiogram.
    2. Tinnitus–none, same, better, worse.
    3. Vertigo–none, same, better, worse.

Patient Information

Stapedectomy/Stapedotomy is a middle ear operation to restore hearing related to a frozen bone or
bones in the middle ear. This allows improvement of hearing by restoring vibration of the middle ear
bones to the fluid of the middle ear.

Complications from stapedectomy are infrequent and are usually related to uncommon variations in anatomy or birth defects. The likelihood of total hearing loss is rare. Facial paralysis is extremely rare for stapedectomy. Loss of taste on the side of the tongue is a common complaint that usually resolves within a few months. Some dizziness after surgery is normal and may last several days or weeks. Severe or disabling dizziness is less common and could be a symptom of inner ear disturbances. Tinnitus that was present before surgery commonly persists, but could disappear or diminish. On the other hand, tinnitus may develop as a result of surgery.

Failure to improve hearing occurs in about 2% of cases. If there is deterioration of hearing after successful surgery and adequate nerve function remains, it may be possible to restore that hearing by additional surgery. The likelihood of success in those cases has been estimated at 60-80%. A hearing
aid may be a reasonable alternative to surgery and that option should be discussed. Unless otherwise
advised by your surgeon, stapedectomy for otosclerosis is an elective procedure.
