[Heat conductivity measurements on different tissues and their significance for laser surgery of the larynx (author's transl)].
The heat conductivity of different tissues (cartilage, muscle, extirpated tissue) was measured and compared under continuous application of CO2 and Neodym-Yag laser treatment. After every laser application a continuous rise of the physiological temperature results in the analyzed tissue. The temperature influence on the tissue periphery is much lower in CO2 laser application than using the Neodym-Yag laser. Similarly it is found that the temperature maximum of the CO2 laser is much below that of the Neodym-Yag laser. The CO2 laser seems to be better for larynx surgery of non-malignant tumors, whereas the Neodym-Yag laser seems better for the therapy of malignant tumors, even though the general application in these cases is still questionable.
