Sonographische Halsanatomie und ihre Bedeutung beim Lymphknotenstaging von Kopf-Hals-Malignomen

Our experience with sonography of the neck (about 1,500 examinations) indicates that most of the structures that are of therapeutic importance can be demonstrated by ultrasound. The cervical nerves, however, cannot be differentiated sonographically from perivascular fat because there is insufficient impedance difference presented by the myelin sheaths. The typical sonographic anatomy of the anterior and lateral cervical muscles, of the major vessels, the thyroid and parathyroid and salivary glands has been analysed. The structures that can be shown by sonography have been related to dissections of the neck.
