Restoration of broken cytology slides and creation of multiple slides from a single smear preparation.

: A technique was developed for restoring broken cytology slides so that they are close to their original condition and for making multiple slides from a single smear preparation. The method is applicable to both cytologic preparations and histologic sections. In this study the fragmented smear preparation was treated with Pro-Texx, which penetrated, impregnated and solidified the full thickness of the pieces of the smear, enabling them to be lifted from the pieces of the broken slide. The removed pieces of the smear preparation were reassembled onto a new slide, which was then restained and coverslipped. In preparing multiple teaching slides, the treated smear preparation was divided as planned, with each portion mounted onto a separate slide, which was then restained and coverslipped. Ten other fine needle aspiration cases with broken slides have been restored, and more teaching slides were prepared from a single smear preparation using the same technique. All were equally successful. This technique provides an excellent method of smear transfer in cases of broken slides and creation of multiple slides from a single smear preparation for cytology teaching. This is particularly useful for unusual cases.
