[Sonographic diagnosis of head and neck tumors in association with therapy]

Basing on the experience with 558 patients suffering from tumours or suspicious lesions in the head and neck region, sonographic pointers that have been inadequately noted so far, are pointed out to improve diagnosis, follow-up, and post-therapeutic care. Among the possibilities offered by sonography are: to confirm or exclude bony involvement of the mandible in tumours of the oral cavity and the oropharynx, to objectify the results of antineoplastic chemotherapy, to offer possibilities to optimize radiotherapy, as well as to show criteria for the early detection of a relapse under consideration of the primary therapy.
