Comparison of Free-Beam- and Fiber-Type CO2 Laser Delivery Systems in Stapes Surgery

摘要

Background and ObjectivesA free-beam-type CO2 laser, which use a micromanipulator mounted on a microscope as the delivery system, has the merit of not being affected by hand tremor at the time of shooting. However, this delivery system has several disadvantages, including a restricted operation range and a risk of incorrect focusing. A fiber-type CO2 laser uses a hand-held delivery system and has the opposite merits and demerits. We compared the results of stapes surgery with free-beam and fiber type delivery systems.
