Comparative analysis between sutured elliptical excision and shaving of intradermal melanocytic nevi: a Randomized Clinical Trial

Introduction: Although the intradermal melanocytic nevi are benign lesions, many patients seek for dermatologists for their excision. However, there are no studies about the best method for this procedure.
Objective: To compare in a randomized clinical trial the excision of intradermal melanocytic nevi in the face for shaving and elliptical excision with suture
Methods: Patients with intradermal melanocytic nevi on the face were selected for removal by shaving or ellipse, randomly. The results were described regarding patient satisfaction and photographic records evaluated by a blinded physician.
Results: 18 patients underwent excision of intradermal melanocytic nevi. The mean scar size after six months of the procedure was of 8,11mm for the excision in ellipse and 2,92mm for the shaving (p < 0.05). The mean score of the patients after six months was 9.67 (ellipse) and 9.57 (shaving) (p = 0.8). The mean by the blinded physician was of 7.78 (ellipse) and 7.86 (shaving) (p = 0.91). 28.6% of patients undergoing shaving had recurrence of the nevus.
Conclusions: The two forms are of excision are equivalent concerning patients satisfaction and the judgment of medical team about the aesthetic results of the scar. However, ellipse with suture excision has the advantage of having a lower relapse.
