Cytospray fixation of frozen intraoperative sections.

Preservation of cellular morphologic features is well known to be a limit of intraoperative frozen sections. Various techniques have been proposed to improve tissue details, the most common being ethanol immersion of cryostatic slide. We tested fixation with spray formulation for cytology smears on intraoperative frozen section from different organs to obtain a quick alcoholic fixation and a ready-to-use method. Our results of comparative study showed that cytospray fixation of frozen sections provide a significant improvement of cellular details, that it is quick, simple, economic, and that it does not require preorganization.
