The proximity of head and neck (HN) melanomas to critical anatomical structures requires that surgeons achieve a balance between adequate margins of excision and the functional and cosmetic needs of patients. This study sought to determine the risk associated with reducing margins of wide local excision (WLE) in HN melanoma and to identify risk factors of recurrence.Seventy-nine cases of primary, invasive HN melanoma were treated by WLE and followed prospectively for local recurrence. Forty-two WLEs were performed according to current practice guidelines (1cm for lesions1.0 mm thick, 1-2 cm for lesions 1.01-2.0 mm thick, and 2 cm for lesions2.0 mm thick). Reduced margins (0.5 cm for lesions ≤1.0 mm thick, 0.5-1.0 cm for lesions 1.01-2.0 mm thick, and 1.0 cm for lesion2.0 mm thick) were utilized in 37 cases to preserve critical anatomical structures such as the eyelid, nose, mouth and auricle.Overall local recurrence rate was 8.9% over a mean follow-up period of 71.3 months and a minimum of 60 months. Reducing margins of WLE did not increase local recurrence rates as demonstrated by local recurrence-free survival (90.4% vs. 91.9%, P = 0.806).Margins of WLE may be safely reduced in melanomas in close proximity to structures of the HN without affecting local recurrence rates. |
