Abstract
Recovery of tongue mobility in speech was investigated in 5 partial glossectomy patients. Jaw range of motion used in speech, and tongue contour changes relative to the jaw, were assessed using sequential videofluoroscopic data recorded presurgery, postsurgery, and postradiotherapy. Data from 2 normal controls were included for comparison. Tongue mobility relative to the jaw was found to be restricted postsurgery. Approximately 4 months later, following radiotherapy, tongue mobility increased. Range of jaw motion used in speech was unchanged. Results are interpreted as preliminary evidence that in this small group of cancer patients, radiotherapy following surgery did not prevent continued recovery of tongue function for speech in the early postradiation period.
