Tumor Margin Assessment With Loupe Magnification Enables Greater Histological Clearance of Facial Basal Cell Carcinomas Compared With Clinical Examination Alone.

BACKGROUND: Surgical excision of facial basal cell carcinomas (BCCs) is a balance between oncological clearance and conservation of cosmetic and functionally sensitive tissues. OBJECTIVE: To assess if loupe magnification (LM) can enhance the visual assessment of BCC tumor margins resulting in a greater histological clearance. METHODS AND MATERIALS: This prospective study randomized patients with primary facial BCCs into preoperative tumor margin assessment with LM (study group) or clinical examination alone (control group). Basal cell carcinomas were excised with a predetermined surgical margin of either 2, 3,, or 4 mm. Mean histological margin, incomplete excision rate, and method of closure were recorded and compared between LM and control groups, across a range of surgical margins. RESULTS: Ninety-four BCCs were excised from 93 patients, 47 BCCs in each group. The mean histological margin was larger in the study versus control group for each group (2-mm margin, 1.8 vs 1.4, 3-mm margin, 2.4 vs 2.3, 4-mm margin, and 3.1 vs 2.7), but only statistically significant in the 4-mm group (p = .032). There was no difference in method of closure between LM and control groups. CONCLUSION: Loupe magnification improved tumor margin assessment for facial BCC enabling a greater diameter of histological clearance. The use of LM should become a standard practice for facial BCC excision. (C) 2017 by the American Society for Dermatologic Surgery, Inc. Published by Wolters Kluwer Health, Inc. All rights reserved.
