Parotidectomy in patients with head and neck cutaneous melanoma with cervical lymph node involvement.

BACKGROUND

Parotidectomy in melanoma of the coronal scalp and face with clinically involved cervical lymph node metastasis is based on predicted cervical lymphatic drainage described by O'Brien.

METHODS

In total, 40 parotidectomies with en bloc therapeutic neck dissection were retrospectively analyzed.

RESULTS

Lymphatic spread of melanoma to the parotid lymph nodes was observed in 10 of 40 specimens (25%). Eight of the 10 parotid-positive patients developed a recurrence vs 17 of the 30 parotid-negative patients (P = 0.28). There were no differences in overall survival, melanoma-specific survival, and disease-free survival between the parotid-positive and parotid-negative patients.

CONCLUSION

Although in this series no survival differences were found, parotidectomy still merits a sustained role in therapeutic neck dissection procedures to improve regional control and to prevent facial nerve damage after surgery for a second relapse from occult metastases in the parotid.
