Oral rehabilitation by prosthetic restoration after maxillectomy for malignant tumors.

In maxillectomy patients, speech intelligibility between before and after insertion of prostheses has been reviewed by many investigators. Speech intelligibility was not related to the size of the defect, but rather to the defect region. Speech intelligibility was considerably improved by the use of prostheses. A great difference could not be found in escape rate from the nasal cavity between before and after insertion of prostheses, but there was a remarkable change in the spirometer. Postmaxillectomy functions are also easily restored by prosthetic oral rehabilitation, necessary to aid surgical procedure.
