Example text

The great advantage of face down embedding is that the tissue face which we will be cutting, freezes in a single flat plane. The surface will require less trimming and wastage of tissue before the entire tissue face is available for sectioning. One traditional method of face down embedding of frozen section tissues has been performed using disposable plastic molds, sometimes referred to as boats. Tissue is placed on the floor of a mold which is then filled with medium. 3 Face up embedding on a chuck with a prepared flattened base of frozen embedding medium.

Pre-chilling can be easily accomplished on any small piece of metal or ceramic kept in the refrigerator. Place the tissue on the cold surface for a few seconds on each side to bring the tissue temperature closer to freezing temperature before placing the tissue in the well. 3 Cold Embedding Medium Using well bars, the tissue face rapidly begins freezing on touching the well floor. Small pieces will essentially completely freeze in the first few seconds. However, the tissue is re-warmed when we fill the well with warm embedding medium.

This may make it easier to get the tissue into a position to make such a fine controlled cut. Beware of cysts! It is wise to exert minimal pressure with the fingers and scalpel when cutting tissue that is grossly cystic or may contain small cysts. When we squeeze tissues with our hands and press firmly with a scalpel, we raise the pressure in any cystic components. As the scalpel blade encounters these cysts under pressure the contents will squirt out of the tissue like a pin hole in a water balloon.
