Area of Science:

  • Otolaryngology
  • Surgical Innovation
  • Audiology

Background:

  • Otosclerosis is a common cause of conductive hearing loss.
  • Stapedotomy is a surgical procedure to restore hearing in otosclerosis patients.
  • Traditional microdrilling carries risks to delicate ear structures.

Purpose of the Study:

  • To compare the efficacy and safety of piezoelectric device-assisted stapedotomy versus traditional microdrilling.
  • To evaluate the impact of the piezoelectric device on surgical precision and patient outcomes.

Main Methods:

  • A prospective, randomized, controlled trial involving 100 otosclerosis patients undergoing primary stapedotomy.
  • Fifty patients were treated with a piezoelectric device, and 50 with a microdrill.
  • Comprehensive audiological and otomicroscopic evaluations were performed pre- and post-surgery at 1 and 12 months.

Published on: March 2, 2018

Main Results:

  • All patients (100%) using the piezoelectric device achieved significant air-bone gap reduction (within 10 dB).
  • 88% of patients undergoing traditional microdrilling achieved similar air-bone gap reduction.
  • The piezoelectric device demonstrated excellent safety and cutting precision.

Conclusions:

  • The piezoelectric device is a safe and effective tool for stapedotomy.
  • It offers superior cutting precision and protection of the middle and inner ear structures.
  • The device is applicable and beneficial for stapedotomy procedures in otosclerosis treatment.
