[Significance of the hemostatic effect of lasers in oral surgery]

The authors summarize the operative experiences performed with CO2 laser in 352 cases of oral surgery with special regard to the hemostatic effect. One of the patients suffered from hemophilia, 5 from thrombocytopenia and 5 from hypoprothrombinemia. Of the alterations to be eliminated 128 were especially inclined to hemorrhage (hemangioma, epulis, granuloma fissuratum). The operations were carried out with out-patients in local anesthesia. Due to the hemostatic effect of the laser the surgery could be performed in dry operative areas, the laser knife coagulates in the course of cutting the small vessels. Both in the group of patients with hemorrhagic diathesis and in the group of operation of alterations inclined to bleeding the experiences were highly favourable. No significant differences were found between the group of patients with hemorrhagic diathesis and other patients in the respect of the duration of operation, degree of bleeding, healing of the wound and complication. CO2 laser of high energy was found to be well applicable in the field of oral surgery owing to its excellent hemostatic effect, especially in operations where the patient or the alteration to be removed (possibly both) are disposed to bleeding.
