| Research Abstract |
The subjects in this study consisted of 44 mandible, tongue, oral floor tumor patients. Masticatory performance was measured using a testing gummy jelly at five stage: before surgery, and 1, 3, 6, 12 months after surgery. Multiple linear regression analysis for searching factors influencing the recovery of masticatory ability after surgery(p<0.05). Among items on cancer treatment, resection of tongue base, neck dissection, resection of mandibular bone and radiotherapy were chosen as negative factors for the recovery of masticatory ability, in contrast chemotherapy was chosen as a positive factor. These results would enable us to predict the recovery of post-operative masticatory ability which might be useful for the informed consent before surgery as well as for developing effective rehabilitation strategy.
