The authors have studied the prosthetic treatment of cases of speech disorder caused by the operation of maxillary cancer.
33 cases, applied gauze pack or prosthesis to the resected maxilla, were estimated the grade of speech disorders with pronunciation test. They also were examined the decrease ratio of vital capacity and the relationship between the soft palate on the operated side and the degree of speech accuracy.
The prosthesis was most effective to cure a patient of speech disorder, although some nasalization still remained. The obturator of prosthesis occupying the resected maxilla exerted a delicate influence upon pronunciation. When it occupied about 70% of the defect, pronunciation was best. But the prosthesis has to be improved in its form, hardness and elsewhere.
The wider the remaining area adjacent to the choanae of the soft palate on the operated side, the better was pronunciation. But its width on the buccal side seemed to have little to do with pronunciation.
