Stapes surgery effectively corrects conductive hearing loss in children with otosclerosis and congenital stapedial fixation. Juvenile otosclerosis surgery yields excellent hearing results, while congenital fixation and revision surgeries show varied outcomes.

Area of Science:

  • Otolaryngology
  • Pediatric Otology
  • Surgical Audiology

Background:

  • Stapes surgery is a standard treatment for adult otosclerosis-induced conductive hearing loss.
  • The efficacy of stapes surgery in pediatric populations is less documented.
  • Prior studies suggest comparable outcomes between children and adults undergoing stapedectomy.

Purpose of the Study:

  • To evaluate the effectiveness of stapes surgery in children with conductive hearing loss.
  • To compare outcomes between congenital stapedial fixation and juvenile otosclerosis.
  • To identify factors influencing surgical success and complications in pediatric stapedectomy.

Main Methods:

  • Retrospective review of 95 stapedectomies performed on 81 patients under 18 years old (1980-1994).

  • Analysis of patient data including age of onset, family history, surgical findings, and hearing results.
  • Categorization into congenital stapedial fixation and juvenile otosclerosis groups for comparative analysis.

    • Main Results:

    • Overall hearing improvement was observed in 79% of primary and 89% of revision cases.
    • Excellent hearing results (air-bone gap ≤ 10 dB) were achieved in 82% of juvenile otosclerosis cases versus 44% of congenital stapedial fixation cases.
    • Poorer outcomes in congenital fixation and revision surgeries were associated with malleus and incus anomalies.

    Conclusions:

    • Stapes surgery is effective for conductive hearing loss in children, with juvenile otosclerosis showing superior outcomes.
    • Congenital stapedial fixation and revision stapedectomies present unique challenges, often linked to anatomical abnormalities.
    • This study highlights the importance of considering specific etiologies and associated anomalies when performing stapedectomy in children.
