Predicting the Surgical Margin of Resection in Periocular Cutaneous Neoplasms and the Significance of Reconstruction Following Mohs Micrographic Surgery

Abstract

Standard 3 mm to 4 mm MOR for BCCAs, and 5 mm MOR for SCCAs could result in an unacceptable risk of tumor recurrence if the surgical margins are not examined histologically. With increasing preoperative tumor size, there is an increase in the MOR required for BCCA and SCCA, supporting that large tumors require a greater MOR.
