Carcinoma of the floor of the mouth. Successful results with monoblock resection and suprahyoid dissection in early lesions.

In 33 cases of carcinoma of the floor of the mouth, the lesions were classified according to the extent of invasion and involvement and a plan of surgical procedure was followed that fitted the operation to the classification.A monoblock resection plan for early intraoral lesions appeared to be quite satisfactory. It was used in two cases in which node involvement was not known until discovered in the pathologic specimen, but in neither case was there recurrence in a period of six years.
