Abstract
Utilization of a posterior neck dissection in the treatment of nine patients with malignant melanoma of the posterior scalp is presented. Seven of nine patients presented with metastatic disease present in the posterior neck after initial treatment elsewhere. Four of the seven patients developed regional disease 4 months to 4 years following initial diagnosis. Variables dictating surgical treatment included the Clark's level, Breslow depth of invasion of original lesion, evidence of metastatic disease, and type of melanoma. The surgical technique of the posterior neck dissection is graphically depicted and the indications outlined. The posterior neck dissection is mandatory to adequately resect the primary lymphatics of the posterior scalp. Controlled studies are urged to determine the efficacy of prophylactic surgical lymphadenectomy in malignant melanoma of the head and neck.
