A New Embedding Method for Optimal Tissue Preparation for Mohs Mierographic Surgery
Abstract
-
BACKGROUND: The principle of Mohs micrographic surgery is to examine microscopically the entire peripheral margin of an excised tissue specimen to precisely localize the site of any residual tumor and enable its subsequent removal. In processing in the tissue for frozen horizontal sections, a technical difficulty arises in manipulating the deep and lateral margins into the same flat plane.
OBJECTIVE
Our aim was to develop a new method allowing the optimal tissue preperation for Mohs micrographic smgery and to evaluate the usefulness of this methad.
METHODS
The technique involves conversion of a non-planar surgical margin to a planar surface by applying and freezing the specimen against a flat glass surface. We compared this modified method used in our laboratory with standard methods for tissue preparation of Mohs micrographic surgery.
