The authors have used since March, 1980 a high-powered carbon dioxide laser surgical unit (MEDILASER-S, MODEL MEL-442, maximum output 60W) for experimental, histomorphological observations and clinical purposes. Up to now, laser surgery has been applied to 19 cases in total. Namely, it was performed in 6 cases for the purposes of radical or quantity-reducing operations of cancer in the head and neck, that is, 2 cases of cancer of the tongue and the oral cavity, 1 case of cancer of the pharynx and 3 cases of cancer of the nasal and paranasal cavities. It was also applied to 3 cases of D-P skin-flap formation, 7 cases of diseases of the oral mucosa such as leukoplakia, papilloma and intractable ulcer and 3 cases of verruca in the external of the auditory meatus and the nasal vestibule. Since laser surgery is often effective for the lesions which are difficult to control by conventional methods and has a mechanism of action quite different from those of conventional operations and X-ray irradiation, it seems to play a unique role especially in the treatment system of head and neck cancer.
