[Choice of tools for ambulatory uvulopalatoplasty on the basis of experimental and clinical studies].

We studied interaction of a radiofrequency scalpel and a semiconductor laser with the tissue phantom. The heated part of the phantom can be easily removed and measured for size of the coagulated area. We investigated to what extent the width of the coagulation necrosis along the incision is influenced by the power and speed of each instrument used for incision.
