FIELD: surgery; oncology. SUBSTANCE: method is based on following fundamental premises: while practising classical or functional dissection of neck, during excision of tissue to be removed, jugular lymphatic trunk is unavoidably dissected from below, since this trunk is not identified in wound. As result, as tissues to be removed are drawn into wound, lymph flows out. This fact creates real threat for implantation of cancer metastases and constitutes, probably, main reason for appearance of metastases on neck after technically correctly performed surgical operation. What is more, even if jugular lymphatic trunk is identified and ligated, conditions are created during surgeon's work with tissues to be removed for further propagation and retrograde penetration of cancer metastasis along lymphatic viae. Method is inventively novel and resides in that, in order to prevent possibility for development of implanted metastases during dissection of neck, jugular lymphatic trunk is identified and catheterized, followed by applying ligatures onto trunk below catheter so as to keep catheter in portion of lymphatic trunk associated with block of tissues to be removed. Lymph excreted during work with block of tissues if directed beyond limits of operative wound. EFFECT: method can be recommended for use in surgical treatment of malignant tumors in maxillofacial area.
