The purpose of this paper is to describe my experiences in the staining of cervical lymphatic nodes in cases of malignant tumors of the upper respiratory tracts with direct sky blue to facilitate the radical neck dissection.
It is a well-known fact that malignant tumors of the upper respiratory tracts, including the oral cavity, form metastasis in cervical lymphatic nodes. In spite of this fact, it cannot be denied that the treatment of cervical lymphatic nodes in the surgery of malignant tumors in our field has been rather conservative. Almost all surgeons who are engaged in treating malignant tumors of the upper respiratory tracts would have seen, if they had neglected unpalpable cervical lymphatic nodes or if they had extirpated only a few palpable ones, that metastasis following the operation was often fatal for patients. This is the reason why radical neck dissection has been advocated. Indeed, we can often
