Stapedotomy with a teflon loop prosthesis effectively restores hearing in most otosclerosis patients. This surgical procedure for otosclerosis is safe, with uncommon complications.

Area of Science:

  • Otolaryngology
  • Surgical Innovation
  • Audiology

Background:

  • Otosclerosis is a common cause of conductive hearing loss.
  • Stapedotomy is a surgical procedure to improve hearing in otosclerosis patients.
  • Teflon loop prostheses are used to reconstruct the stapes footplate.

Purpose of the Study:

  • To evaluate hearing improvement after stapedotomy using a teflon loop prosthesis for otosclerosis.
  • To assess the efficacy and safety of this surgical technique.

Main Methods:

  • A quasi-experimental study was conducted with 30 diagnosed otosclerosis cases.
  • Stapedotomy was performed using a 4-4.5 mm teflon loop prosthesis on the ear with the larger air-bone gap.
  • Patients were followed up for one year, with postoperative air-bone gap measurements.

Main Results:

  • Good hearing improvement (air-bone gap closure up to 10 dB) was observed in 56.7% of patients.
  • Fair improvement (11-20 dB closure) occurred in 30%, and poor results (>21 dB) in 10%.
  • Mild postoperative vertigo was transient; one patient developed a dead ear.

Conclusions:

  • Stapedotomy with a teflon loop prosthesis is an effective treatment for hearing loss in otosclerosis.
  • The procedure demonstrates a favorable outcome profile with a low complication rate.
