What does cryosurgery mean?
Cryosurgery generally refers to a surgical procedure that uses the low temperature of cryogenic agents to destroy certain diseased tissues and achieve therapeutic purposes.
In clinical practice, cryosurgery typically employs cryogens such as liquid nitrogen to generate extremely low temperatures. This causes ice crystals to form within the cells of the affected tissue, leading to cellular dehydration, denaturation of lipoprotein complexes, and local circulatory disturbances. These changes result in gradual necrosis, scabbing, and shedding of the diseased tissue, thereby achieving the desired treatment outcome. This method is commonly suitable for superficial benign skin tumors, pigmented lesions, molluscum contagiosum, and similar conditions.
After undergoing cryosurgery, patients are advised to pay attention to proper local wound care to prevent secondary infections caused by adverse factors, which could impair recovery.
