[Secondary metastases after neck dissection (author's transl)].

Hundredfourty-eight patients who underwent three types of neck dissection for cervical lymphadenopathy for squamous cell cancer of the head and neck were analysed retrospectively. In patients with no recurrence of the primary tumour the secondary metastases appeared in 44% after suprachyoid neck dissection, in 33% after classical and in 19% after modified neck dissection.
