Cryotherapy Gun Control

May 8, 2009

It can be difficult to regulate the output of a cryotherapy gun-and the extent of freezing that results. Using a disposable ear speculum to direct the spray helps ensure that the liquid nitrogen hits only the wart or other lesion. Bear in mind that the speculum can get very cold when used in this way; holding it with some gauze helps.
