This study compared microdrill and diode laser techniques for endoscopic stapedotomy in otosclerosis patients. Both methods yielded similar hearing improvements, but the microdrill approach offered a significantly shorter surgical time.

Area of Science:

  • Otolaryngology
  • Surgical Techniques
  • Audiology

Background:

  • Otosclerosis treatment often involves stapedotomy.
  • Microdrill and diode laser are utilized in endoscopic stapedotomy.
  • Direct comparative studies of these techniques are limited.

Purpose of the Study:

  • To compare the efficacy and outcomes of microdrill versus diode laser in endoscopic stapedotomy for otosclerosis.
  • To evaluate differences in surgical time, hearing results, and complications between the two techniques.

Main Methods:

  • A randomized clinical trial involving patients with otosclerosis.
  • Patients were allocated to either the microdrill group (n=69) or the diode laser group (n=62).
  • Key outcomes including preoperative and postoperative air-bone gap, surgical duration, and complications were compared.

Main Results:

  • No significant differences were observed in preoperative or postoperative air-bone gap between the microdrill and diode laser groups.
  • Surgical time was significantly shorter in the microdrill group (48 ± 25.62 minutes) compared to the diode laser group (64 ± 31.23 minutes).
  • No significant differences were found in bleeding volume or postoperative dizziness between the groups.

Conclusions:

  • Endoscopic stapedotomy using either microdrill or diode laser provides equivalent hearing improvement for otosclerosis.
  • The microdrill technique offers an advantage due to its significantly shorter operative time.
  • Both methods are safe and effective, with the microdrill being more time-efficient.
