Since 1979, 120 patients suffering from head and neck malignant tumors have been treated by means of CO2 laser at the laser clinic of Kobe University Hospital. They were divided into two groups. One hundred and four patients were treated for radical treatment and 14 for palliation. Two patients were unknown cases. The equipment employed was a Medilaser S produced by Mochida Co. A special manipulator with 4 joints was manufactured and used as a trial. To utilize the laser as easily as possible, all patients except one were macrosurgically treated under local anesthesia. To exhaust the smoke resulting from laser irradiation, a big vacuum cleaner was used.For the purpose of radical treatment, three methods were applied for fresh and recurrent cases: 1) laser only: All of 21 cases could be locally controlled after the primary therapy. Satisfactory results were obtained using the laser scalpel in tongue cancer. 2) a) combined therapy with cryosurgery: 14 of the 17 cases could be locally controlled after the primary therapy. b) combined therapy with radiotherapy: 9 of the 10 cases could be locally controlled after the primary therapy. This combined therapy was effective for those recurring after ordinary operations. 3) multidisciplinary treatment with radiotherapy, chemotherapy, hyperthermia and cryosurgery. This treatment was applied to the most advanced cases. Forty-one of the 49 cases could be locally controlled after the primary treatment (except the cases of under treatment). In this treatment antrostomy, vaporizing tumor tissues, enlargement of the fenestra, and excision of hard and soft palates invaded by tumor were easily performed by laser surgery. Satisfactory results were obtained in maxillary sinus carcinoma. Laser was effective for prolongation of life and reducing pain in palliative cases. The side effects were negligible.
