Abstract

The purpose of this study is to clarify the usefulness of CO2 laser in Oral and Maxillofacial Surgery. The CO2 laser surgery was performed on 24 patients of oral cancer and 22 patients of oral benign diseases at the Oral Surgery of Hokkaido University Dental Hospital between 1981 and 1984.<BR>The results arc as follows: The CO2 laser surgery seemed to be very effective in Oral and Maxillofacial Surgery because it's hemostatic ability and visualization of the operative field make the operation precisely. For the best application of CO2 laser, <BR>1) Retractors and traction sutures must be used precisely in order to keep the operative field.<BR>2) The operative field must be dry and the vessels larger than 0.5mm in diameter must be coagulated by ligation or electrocauterization.<BR>3) It seems to be the best that the power of laser is set with the range from 5 to 10 watt and the spot size is adjusted to the diameter from 0.5 to 3.0mm as defocused beam.
