[Possibilities of lymphoscintillography in head and neck surgery (II): results of clinical evaluation].

In order to determine the value of lymphoscintigraphy the clinical results were compared to the lymphoscintigraphic findings. The latter were further compared to the histological results and to the isotope activity of single lymph nodes. The examination was performed in 31 cases of head and neck malignancies before neck dissection (in 29 cases radical neck dissection was done because of palpable lymph nodes; in 2 further cases elective neck dissection was performed on the NO neck). Lymphoscintigraphy yielded evaluable results in 28 cases. Lymphoscintigraphy correlated with the clinical results in 21 cases. Lymphoscintigraphy, histopathology and clinical examination showed correlation in 19 cases. Further application of head and neck lymphoscintigraphy is warranted.
