title: Technique for histological control of surgical margins in lip cancer.
abstract: To preserve oral function and achieve acceptable cosmetic results, intraoperative control of surgical margins with frozen section evaluation may help to determine surgical technique in lip cancer. However, frozen section analysis is usually limited to suspicious areas and has not been systematically performed among surgeons. The accuracy of such analysis for detecting histological surgical margins is highly dependent on the methods used to obtain and analyze the margins. Improving the pathodiagnostic reliability of conventional intraoperative frozen section evaluation is the most important goal of surgical management in our method. We describe the successful use of the "double-blade method" in lip cancer treatment. The technique we describe has the advantage of histologically confirming clear margins in lip cancer. This method appears to be time-saving and easy to apply with existing surgical systems. In addition, this method may be used as an alternative to complete evaluation of lateral surgical margins that is important in planning a suitable surgical reconstruction procedure in lip cancer at many institutions where Mohs micrographic surgery is difficult to perform.
