Laser-assisted myringoplasty uses a KTP-532 laser to fuse collagen fibers, enabling tissue growth. This minimally invasive technique offers advantages for eardrum repair, particularly in anterior perforations.

Area of Science:

  • Otolaryngology
  • Biomedical Engineering
  • Laser Surgery

Background:

  • Traditional myringoplasty involves open surgical techniques.
  • Laser technology offers potential for minimally invasive tissue welding.
  • Collagen fiber fusion by lasers creates strong tissue bonds.

Purpose of the Study:

  • To evaluate the applicability of laser technology in myringoplasty procedures.
  • To assess the efficacy and safety of KTP-532 laser for eardrum repair.

Main Methods:

  • Outpatient myringoplasty using a KTP-532 laser.
  • Laser delivery via micromanipulator or silica fiber.
  • Perichondrium grafts from the tragus used as transplant material.
  • Laser settings: 2-4 W for perforation margin evaporation, 0.2-1.5 W for graft welding.

Main Results:

  • Successful tissue fusion and bonding observed.
  • Minimally invasive approach with no ossicle manipulation.
  • Advantages noted for anterior perforations, enabling endoscopic procedures.
  • Surgical failures linked to thermal damage; fiber delivery preferred for better control.

Conclusions:

  • Laser-assisted myringoplasty is a viable, minimally invasive alternative to traditional methods.
  • The fiber delivery system is preferred for enhanced control and reduced thermal damage.
  • This technique shows promise for treating eardrum perforations, especially anterior ones.
