Description: This study aimed to provide a description of the functional consequences of a partial lateral glossectomy. Using ultrasound, the midsagittal tongue movement of 10 patients with tongue cancer and 6 adults with normal speech was analyzed. The midsagittal tongue elevation during speech, the velocity of midsagittal tongue movements, the vowel space, and the speech intelligibility and acceptability were compared. Within-subject comparisons were made for the patients pre- and post-glossectomy. Between-subject comparisons were made for patients with local closure and those with free flaps, and for tongue cancer patients and adults with normal speech. The results indicated that the partial glossectomy patients compensated for the loss of lateral tongue tissue by elevating their midsagittal tongues to a higher level and by increasing the velocity of movement during speech. The results also revealed that the patients with higher tongue velocity had less intelligible speech than those with lower tongue velocity.
