Otosclerosis


  1. General information
    1. Formation of new spongy bone in the labyrinth of the ear causing fixation of the stapes in the oval window; this prevents transmission of auditory vibration to the inner ear
    2. Found more often in females
    3. Cause unknown, but there is a familial tendency
  2. Medical management: stapedectomy is the procedure of choice.
  3. Assessment findings
    1. Progressive loss of hearing
    2. Tinnitus
    3. Diagnostic tests
      1. Audiometry: reveals conductive hearing loss
      2. Weber's and Rinne's tests: show bone conduction is greater than air conduction
  4. Nursing interventions: see Stapedectomy.
