“…Aerosol or liquid nitrogen freezing either on a glass slide, plastic plate, or x-ray film is another technique commonly used to flatten tissue. However, in addition to those five methods in the questionnaire, there are other methods used in our survey such as the ''cryoembedder,'' mechanical or hand flattening, Weber's technique, 4 tissue glide, and heat-extractor flattening on a glass slide. Each method of tissue flattening has its own limitations and advantages.…”

“…Most of the techniques focus on reducing the tension intrinsic to the skin to minimize cryocontraction of the dermis, which pulls up the epidermis if not incisionally released [10]. Ideally, if the specimen's size permits, Fig.…”

Accurate, efficient frozen section analysis is important for tumor control. A few studies address the technical issues. More are needed, especially as new technologies become available. The objective of this study is to compare the efficiency of three techniques of flattening tissue for microscopically oriented histologic surgery (MOHS): conventional frozen sectioning, Cryocup, and CryoHist. Conventional chuck/heat sink-frozen section preparation were compared with Cryocup and CryoHist to determine the most efficient technique to examine 100% of the surgical margin of 4-cm diameter, full thickness, fresh autopsy cylinders of anterior abdominal skin, which were marked on their deep and peripheral margins. The specimens were frozen sectioned at 5 microm until all the marking dye was gone from the deep surface, and 95% of the perimeter epidermis could be seen. The conventional chuck required an average of 304 micrometers to clear the deep margin and four fifths did not contain 95% of the epidermal margin. The Cryocup required an average of 284 microm to examine the deep margin and 95% of the epidermal margin. The CryoHist required an average of 104 microm to examine the deep margin and 95% of the epidermal border. The new techniques improve the efficiency and presumably the accuracy of tumor margin analysis.

“…Literally scores of techniques and machines have been created in the past decades to produce complete margins (Table 1). [15][16][17][18][19][20][21][22][23] Most of the mounting techniques apply force to flatten the outside margin, something largely accomplished by relaxing incisions. In our experience, two of the simpler methods, forceps placement followed by a heat extractor and the Miami Special are the most used and most useful.…”
