%X Context: Stapes surgery is the mainstay of treatment for
  otosclerosis. Reported success rates of stapes surgery for
  otosclerosis vary widely, ranging from 63.6% to 94%. The
  pre-operative prognostic factors of hearing outcomes after
  surgery are not well studied.
Objective: To determine the hearing results after stapes
  surgery and analyze the prognostic role of pre-operative
  factors on hearing outcomes.
Design: Retrospective study.
Setting: Tertiary referral center.
Patients: 90 cases of otosclerosis operated on in our
  institute from 2006 to 2016 were included into the study.
Interventions: Stapes surgery was performed for 90 cases of
  otosclerosis (77 stapedotomies, 13 stapedectomies).
Main outcome measures: Audiograms performed just
  before and six months after operation were used. We
  selected several pre-operative variables for analysis- age,
  gender, unilateral/bilateral disease, air (AC) and bone
  conduction (BC) thresholds, air-bone gap (ABG). Our
  outcomes measured were post-operative AC, ABG and
  percentage improvement in air-bone gap (ABGi). The
  associations between these pre-operative predictors and
  outcomes were then analyzed.
Results: We report 80% (n=72) and 84.7% (n=76) of cases
  achieving ideal ABG (¡Ü 10 dB) and AC outcomes (gain in ¡Ý 20
  dB), respectively. The mean post-operative ABG was 8.8 dB.
  The mean ABGi, was 78.8% with 78.9% (n=71) of cases
  attaining ideal ABGi (¡Ý 70%). Pre-operative variables did not
  significantly influence post-operative AC and ABG results.
  However, patients with larger pre-operative ABG (>30 dB)
  had greater ABGi (85.7 vs. 72.5%, p<0.001).
Conclusion: Stapes surgery provides good and predictable
  results independent of disease severity or patient profile. Consequently, patients with larger hearing impairment are
  likely to benefit relatively more from surgery.
