In the present study, we retrospectively investigated states of occult metastases and recurrent nodes of laryngeal cancer to find appropriate mode of neck dissection for laryngeal cancer. One hundred and eleven patients with laryngeal cancer received treatment at this department from 1989 to 1998 and 30 patients who had undergone neck dissection were available for the present study. As a result, we found 1 case with recurrent node at level N in NO glottic cancer, while two cases of occult metastasis were observed at level II in NO supraglottic cancer. Neither occult metastases nor recurrent node were observed at level V in NO and N1 laryngeal cancer. On the other hand, we experienced some case with occult metastases at level V in N2 glottic and supraglottic cancer. Consequently, we conclude that neck dissection is not exactly essential for NO glottic cancer, but we should perform level II and III neck dissection for NO supraglottic cancer. Level II to N neck dissection is thought to be appropriate for N1 laryngeal cancer. We thought it necessary to perform radical neck dissection or modified neck dissection just for N2 laryngeal cancer.
