title: [Sonography in malignant tonsillar tumors].
abstract: In this retrospective study the value of sonography in the preoperative staging of malignant tumours of the tonsils was evaluated in 36 patients. According to our results sonography is indicated in small tumours. In greater tumours, especially if bone destruction could be expected, MR or CT should be performed additionally to sonography. Good results were achieved in assessing the infiltration of the tongue with or without crossing the midline (accuracy 92 to 97%) and the detection of cervical lymph node metastasis (accuracy 94%).
