title: Hearing results of 1145 stapedotomies evaluated with Amsterdam hearing evaluation plots.
abstract: OBJECTIVE
  To evaluate the hearing results of a large series of primary stapedotomies, according to American Academy of Otolaryngology, Head and Neck Surgery guidelines and Amsterdam hearing evaluation plots.
  
  
  METHODS
  Retrospective chart review.
  
  
  METHODS
  The charts for 1369 consecutive stapedotomy cases were reviewed; 1145 cases of primary stapedotomy were included. Raw data from the audiometric database were evaluated using Amsterdam hearing evaluation plots. The effect on outcomes of using different audiological parameters was analysed.
  
  
  RESULTS
  A significant improvement was demonstrated in mean post-operative air conduction and speech reception thresholds, with no change in bone conduction. Air-bone gap closure of 10 dB or more was achieved in 82 per cent of cases. A 'dead ear' occurred in one patient (0.1 per cent).
  
  
  CONCLUSIONS
  This study reports the largest series of primary stapedotomies evaluated with Amsterdam hearing evaluation plots. This method enables visual identification of successful and unfavourable results, providing more accurate and detailed presentation of surgical outcomes.
