Posterolateral neck dissection: technique and results.

Abstract

Posterolateral neck dissection, alone or combined with a modified radical neck dissection, may be an appropriate method of treating occult and clinically manifest nodal metastases of malignant epithelial tumours of the skin of the posterior scalp. The technique and results are described in 21 patients treated between February 1981 and November 1989. Transformation of nodal status from cN0 to pN+ was seen in five of 13 patients treated electively, who may benefit from such a procedure. During a mean follow-up of 47 months the disease was controlled locally in all patients. Three patients suffered regional recurrence of whom only one had a nodal recurrence within the region previously operated on. The results of this limited retrospective study confirm the value of posterolateral neck dissection in posterior scalp lesions.
