    This study details using an argon laser during tympanoplasty (eardrum repair) to control bleeding and secure grafts. The laser offers a precise method for improving surgical outcomes in eardrum reconstruction.

    Area of Science:

    • Otolaryngology
    • Surgical Technology
    • Biomedical Engineering

    Background:

    • Tympanoplasty involves eardrum repair, often facing challenges with bleeding control and graft fixation.
    • Minimally invasive techniques are sought to improve surgical precision and patient outcomes.

    Purpose of the Study:

    • To evaluate the efficacy of an argon laser in human tympanoplasty procedures.
    • To assess the dual application of argon laser for hemostasis and graft welding.

    Main Methods:

    • Argon laser utilized for hemostasis of small vessels in the external auditory canal and tympanic membrane remnants.
    • Argon laser employed for precise spot-welding of the eardrum graft into its correct anatomical position.
    • Seven tympanoplasty operations were conducted using these laser techniques.

    Main Results:

    • The argon laser effectively controlled bleeding from small vessels during surgery.
    • Precise graft fixation was achieved using the laser's spot-welding capability.
    • Successful outcomes were observed in the seven performed operations.

    Conclusions:

    • Argon laser application is a viable and effective method in tympanoplasty.
    • The laser provides benefits for both intraoperative hemostasis and graft securement.
    • This technique holds promise for advancing eardrum repair surgery.
