Comparative morphological investigation on the rabbit's auricle after exposure to CO2- and Nd:YAG-laser radiation.
By comparing the effects of CO2- and Nd:YAG-laser radiation (mainly differing in wave-length by a factor of 10), a surgical instrument suitable for Otorhinolaryngology had to be found. The studies were performed on the rabbit's auricle in order to examine the effect of the laser irradiation mainly on the cartilage. The CO2-laser was found to be more efficient in cutting and caused less extended tissue damage than the Nd:YAG-laser. The latter seems to be more suitable for soft tissue surgery.
