Paper Abstract

The purpose of this investigation is to determinate the ablation threshold of 1341 nm Nd:YAP laser radiation in the larynx of rabbits. In this study, 30 treatments with the Nd:YAP laser were carried out. The laser power of irradiation on tissue surface was varied from 4 to 12 W, while the duration of the irradiation was changed from 1 to 2.5 s in 0.5 s increments. The irradiated sample's surfaces were examined for visible signs of ablation under a reading microscope. The results reveal that 6.29×103 and 5.03×103 J/cm2 were the ablation threshold for vocal cord and epiglottis cartilage respectively. The trend of damage diameter and ablation diameter with energy density are also presented.
