The role of parotidectomy in the treatment of nodal metastases from cutaneous melanoma of the head and neck.

Forty-six patients affected by head and neck melanoma were submitted to elective or therapeutic parotidectomy associated with laterocervical dissection from 1980 to 1983 at the National Cancer Institute of Milan. The study showed that parotidectomy is indicated in the presence of clinically palpable nodes or where primaries originate in the temporo-zygomatic area. It also demonstrated that survival is not affected by type of dissection performed and that cervical lymphadenectomy must always be associated with parotidectomy because of the high incidence of occult metastases in other nodal groups in these cases.
