Concerns about visible light lasers potentially harming the inner ear exist. However, this study shows the KTP-532 laser is safe and effective for stapedotomy surgery, achieving good hearing results.

Area of Science:

  • Otolaryngology
  • Surgical Technology
  • Auditory Medicine

Background:

  • Debate exists regarding the safety of visible light lasers for inner ear surgery.
  • Alternative laser types, such as CO2 lasers, have been proposed.
  • Declining numbers of otosclerosis surgery candidates raise concerns about surgical efficacy.

Observation:

  • The KTP-532 laser was used in 80 primary and revision stapedotomies over three years.
  • The author presents personal experience with this laser system.
  • Surgical outcomes included low morbidity and high air-bone gap closure rates.

Findings:

  • The KTP-532 laser demonstrated a low incidence of complications.
  • No apparent cochlear injury was observed in patients undergoing stapedotomy.

  • Effective hearing improvement was achieved, comparable to other methods.

    • Implications:

    • Properly utilized KTP-532 laser systems appear safe for stapedotomy.
    • This technology offers a viable option for stapes surgery, even with fewer eligible patients.
    • The findings support the continued use of KTP lasers in otologic procedures.
