Das Verhalten der Tränenwege nach Kryotherapie von Lidtumoren

Abstract
The advantage of cryotherapy of human eyelid tumors is that it does not destroy the lacrimal points or lacrimal canaliculi. Their patency is kept despite freezing temperatures near to fluid N2 boiling point. To explain this phenomenon, thermoelectrical measurements during, and histological examinations after experimental cryotherapy were performed. Epithelial lesions lasting a few days were noted and the lumen of canaliculi always remained open.
