Lymphoscintigraphy in the head and neck in normals diagnostic value.

The lymphoscintigraphic pattern in the head and neck lymphatics was studied in 45 healthy subjects. After submucous injection of Lymphoscint-solco in the oral cavity there was visualization of regional lymph nodes immediately after food intake. There was an extreme variation in the number of visualized lymph nodes and a lack symmetry between right and left side of the neck. The accumulated radioactivity in subsequent lymph nodes showed an extreme variation. Accordingly no characteristics of diagnostic value could be evaluated from this study.
