Indications for neck dissection in carcinoma of the lip.
In the past, neck dissections have been recommended only when nodes were clinically palpable or when they became so. A retrospective ten year study of thirty-seven patients with carcinoma of the lip and with an unusually high mortality has allowed reevaluation of indications for neck dissection. (1) Ten of thirty-seven patients died of this disease and nearly all of the ten died with and because of regional metastases. (2) Seven patients with nonpalpable nodes initally had nodal metastases later which, despite neck dissection at that later time, proved lethal. (3) Two patients who, despite nonpalpable nodes, had undergone neck dissections and were found to have occult bilateral nodal metastases were effectively cured with early neck dissection. This suggests that early bilateral supramohyoid neck dissections for small carcinomas of the lip and ipsilateral radical neck dissections for large primaries may yield higher cure rates than currently achieved.
