title: [Long-term results after operation of otosclerosis with the use of partial stapedectomy technique after Heermann].
abstract: BACKGROUND
  One of the best method for restoring hearing in otosclerosis is partial stapedectomy according to Heermann's proposition.
  
  
  METHODS
  The retrospective study is refering to 98 patients with otosclerosis who underwent in 1987 year partial stapedectomy after Heermann. The assessment of long-term hearing results was based on audiometric examination after a lapse of 7 years and 15 years.
  
  
  RESULTS
  7 years after the operation we found the improvement of hearing in 90,6% of the patients with the air bone gap (ABG) < 10 dB and in 9,4% of them with ABG 11-20 dB. After 15 years the results were as follows: 23 patients with ABG 0-10 dB, 8 patients ABG 11-20 dB, 1 patients ABG 21-30 dB and 2 patients ABG > 30 dB. Any complications were noted.
  
  
  CONCLUSIONS
  Partial stapedectomy is not only the safe method, but also very cheap with good results.
