The utterance intelligibility test was investigated by a list of 25 monosillables in 70 carcinomas of the oral cavity (59 cases of tongue carcinoma and 11 cases of mouth floor carcinoma) . 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 ;
1) In case of partial glossectomy by laser, postoperative utterance intelligibility was good. There were no problems in the everyday coversation.
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.
3) In cases of partial glossectomy, less than 44mm in anteroposterior length and 15mm in width, there were no problems in everyday conversation.
4) Partial glossectomy including the mouth floor made utterance intelligibility decreased.
