Abstract
The applications of cryosurgery take place among others for causing a local
necrosis of a tissue, the detachment of the bloodless tissue, the destruction of the
cancer cells etc. and these methods of treatment are used in dermatology,
gynecology, proctology, oncology, laryngology and also oral surgery. The
cryoprobe being in thermal contact with the biological tissue causes that the
freezing process proceeds in the domain considered. In this place one can
consider the internal or external cryoprobe.
The problem belongs to the group of moving boundary ones because the shape
and dimensions of frozen region are time-dependent. In the paper the
mathematical model of the process considered and the methods of solution are
presented. Next, the examples of computations are shown.
