Thulium laser stapedotomy is safe and effective for improving hearing in otosclerosis patients. This study found no inner ear impairment, demonstrating its efficacy in both multiple and single-shot techniques.

Area of Science:

  • Otolaryngology
  • Surgical Technology
  • Audiology

Background:

  • Concerns exist regarding Thulium laser's thermal effects and acoustic shock waves during stapedotomy.
  • Potential for permanent complications necessitates safety and efficacy evaluation.

Purpose of the Study:

  • To assess the efficacy and safety of Thulium laser in stapedotomy.
  • To evaluate long-term clinical and audiological outcomes.

Main Methods:

  • Retrospective randomized case-series study involving 148 otosclerosis patients.
  • Patients divided into two groups: Group A (multiple Thulium laser shots, n=62) and Group B (single shot with manual perforator, n=86).

Main Results:

  • Significant air-bone gap (ABG) improvement in both groups; ABG closure (<10 dB) achieved in 87.1% (Group A) and 89.5% (Group B).

  • Higher intraoperative complications in Group B (p=0.038).
  • Higher postoperative complications in Group A (p=0.017).

    • Conclusions:

    • Thulium laser is a safe and effective tool for stapedotomy.
    • Both multiple-shot and single-shot techniques with Thulium laser improve functional hearing without inner ear impairment.
