This investigation was done for each factors ; the way of treatment, the size of removal, and the portion of removal. The results are summarized as follows ;<BR>1) In case of partial glossectomy by laser, postoperative utterance intelligibility was good. There were no problems in the everyday coversation.<BR>2) There was a correlation between the removal size and the utterance intelligibility. The increase in removal size of carcinoma is correlated with the decrease in utterance intelligibility.<BR>3) In cases of partial glossectomy, less than 44mm in anteroposterior length and 15mm in width, there were no problems in everyday conversation.<BR>4) Partial glossectomy including the mouth floor made utterance intelligibility decreased.
