[Radiocinematographic assessment of deglutition after surgical treatment for oral and maxillary neoplasms].

The authors report the results of radiocinematographic examinations of 98 patients operated on for oral and maxillary neoplasms with analysis of the disturbances of various phases of deglutition in relation to the site and extent of the operation. Leakage into lower respiratory tract is discussed. Extensive operations in the mouth and on the lower and upper jaws were found to cause disturbances of both deglutition phases, and retention of contrast in postoperative tissue defects limitation of the movements of various anatomical structures were the most frequent disturbances of deglutition.
