[Sonographic, clinical and surgical correlations in the diagnosis and control of the course of tongue infiltrations].

With a high-resolution sonographic system, anatomical details in the area of the floor of the mouth and tongue are visualized. The value of sonography in the pretherapeutic assessment of suspicious palpation findings was investigated. 22 patients' tumors were examined during radiation, to document the course of therapy. 55 sonograms were evaluated and confirmed the excellent applicability of this procedure in the precise pretherapeutic determination of the size of the lesions and their relation to the surrounding structures. The tumors are readily detected even during radiotherapy.
