Abstract

This chapter discusses cryosurgery, which is the process of destruction of the tissues by rapid cooling to a very low temperature and then thawing. It is based upon the Joule-Thompson effect of the cooling of gases where there is sudden rapid expansion of the compressed gas from high to low pressure through a narrow orifice leading thereby to extremely low temperature. In the operative procedure of cryosurgery, no anaesthesia is given, but a local anaesthetic can be used. Cryosurgery has been widely used in various diseases of the ear, nose and throat, because there is no scar formation and no excision is required. Cryosurgery has the following advantages over other surgical procedures, such as usually no anaesthesia is required, and no haemorrhage or very little haemorrhage, so it can be used in patients with blood disorders. Advantages of cryosurgery are minimal discomfort, no scarring, hardly any bleeding, no anaesthesia and it is an OPD procedure.
