[Cervical dissection in laryngeal cancer: our experience of 15 years].

A retrospective study was made of surgery with cervical dissection in 640 patients with laryngeal carcinoma treated from 1976 to 1991. Cervical dissection was carried out in 386 of 640 patients with laryngeal carcinoma treated surgically. Of a total of 496 cervical dissections performed, there were 173 unilateral functional, 88 bilateral functional, 67 unilateral block, 13 bilateral block, and 27 bilateral block dissections with contralateral functional dissection. The relations between tumor stage (T) and nodal involvement (N), type of dissection and T, type of dissection and N, laryngeal surgery and neck dissection, clinical and histological N, N+ and histologic type, extracapsular spread, number of recurrences, and their relation with T and N, and the relation between N+ and type of neck dissection were studied.
