A comparison of the results of KTP and CO2 laser stapedotomy.

Over the last 10 years, lasers have evolved to become an integral part of stapes surgery. Argon, KTP, and CO2 lasers have all been tested for their improved accuracy and safety in the middle ear. Because of the difference in optical properties between visible light (argon, KTP) and infrared (CO2) lasers, discussions have evolved around which laser is better and safer. In an effort to clarify the issues, a prospective comparison was made of 100 consecutive primary stapedotomies by using either the CO2 or KTP laser.
