Stapedotomy offers superior hearing improvement, especially at high frequencies, and fewer complications compared to stapedectomy for otosclerosis. Modified stapes mobilization may be a future advancement for select patients.

Area of Science:

  • Otolaryngology
  • Neurosurgery
  • Audiology

Background:

  • Otosclerosis causes conductive hearing loss, often treated with stapedectomy or stapedotomy.
  • Both stapedectomy and stapedotomy are established, successful surgical interventions.
  • Long-term stability and high success rates are documented for these procedures.

Purpose of the Study:

  • To compare the short- and long-term outcomes of stapedectomy versus stapedotomy.
  • To evaluate hearing gain, particularly at high frequencies.
  • To assess complication rates associated with each surgical technique.

Main Methods:

  • Comparative analysis of surgical outcomes.
  • Evaluation of audiological results (hearing gain).
  • Assessment of intraoperative and postoperative complications.

Main Results:

  • Stapedotomy demonstrated superior hearing gain at high frequencies compared to stapedectomy.
  • Stapedotomy was associated with lower complication rates.
  • Both procedures showed high rates of success and long-term stability.

Conclusions:

  • Stapedotomy is a preferred surgical option for otosclerosis due to better high-frequency hearing gain and reduced complications.
  • Modified stapes mobilization presents a potential future development in stapes surgery for specific patient groups.
