Laser surgery is an excellent surgical technique. We employed CO2 laser to remove the recurrent small cancerous tissue that developed in the post cricoidal area. The laser beam was irradiated via an operative microscope. At first, the focused beam was used for cutting the tumor and the defocused beam was employed subsequently to reduce the quantity of the tumor. Vaporization was useful for getting rid of the deeper part of the tumor.No significant hemorrhage was observed during the operation.However, because of delayed healing course of wound, a progressive necrotizing lesion occured after surgery. When the coating of necrotic tissue was detached spontaneously from the wound, massive bleeding happened and the patient died from shock. We discussed indications for laser surgery and pointed out factors which have close relations in healing of the wound.
