| Research Abstract |
Tongue movement of articulation was analyzed with ultrasonography on 11 glossectomies (4 underwent direct suture, 2 received split-skin grafts and 5 received reconstruction with free forearm flap).
This study have used a transducer placed submentally, with the beam aimed cephalad toward the tongue. The motion of tongue was clearly described with this application. The amount and the symmetricalness of tongue movement were evaluated in the ultrasonogram and compared with speech intelligibility.
As a result, tongue movement of the glossectomy were smaller in amount and poorer in the symmetricalness than normal. Speech intelligibility is related to the amount and symmetricalness in most of the patients. Especially the symmetricalness influenced speech intelligibility in the rear portion of the tongue.
