Summary

Laser surgery for cholesteatoma may help prevent recurrence but does not improve hearing outcomes. This systematic review found a safe hearing profile and a residual/recurrent cholesteatoma rate between 0% and 33%.

Area of Science:

  • Otolaryngology
  • Surgical Technology
  • Medical Laser Applications

Background:

  • Cholesteatoma treatment primarily involves surgery to remove squamous epithelium.
  • Laser technology offers potential for disease eradication and hearing preservation in middle ear surgery.

Purpose of the Study:

  • To systematically review studies on laser application in cholesteatoma treatment.
  • To evaluate laser's outcomes regarding disease eradication and hearing results.

Main Methods:

  • Systematic literature review conducted on MEDLINE and Cochrane Library.
  • Adherence to PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidance.
  • Inclusion of 12 papers reporting on 536 participants.

Main Results:

  • Laser surgery did not demonstrate hearing improvement or deterioration in cholesteatoma cases.
  • Residual/recurrent cholesteatoma rates ranged from 0% to 33%.
  • The complication rate, specifically facial palsy, was reported as 0.6%.

Conclusions:

  • Current literature suggests laser may aid in preventing or minimizing residual cholesteatoma.
  • Laser application in cholesteatoma surgery appears to have a safe hearing outcome profile.
  • Further large-cohort prospective comparative studies are warranted.
