Cryosurgery (with cryo from the Ancient Greek κρύο ' icy cold ') is the use of extreme cold in surgery to destroy abnormal or diseased tissue; [1] thus, it is the surgical application of cryoablation. Cryosurgery has been historically used to treat a number of diseases and disorders, especially a variety of benign and malignant skin ...
Mohs surgery is the gold standard method for obtaining complete margin control during removal of a skin cancer (complete circumferential peripheral and deep margin assessment - CCPDMA) using frozen section histology. [1] CCPDMA or Mohs surgery allows for the removal of a skin cancer with very narrow surgical margin and a high cure rate.
The use in prostate and renal cryoablation are the most common. Although sometimes applied in cryosurgery through laparoscopic or open surgical approaches, most often cryoablation is performed percutaneously (through the skin and into the target tissue containing the tumor) by a medical specialist, such as an interventional radiologist.
Donor site 8 days after a skin graft. Skin grafting is a surgical procedure where a piece of healthy skin, also known as the donor site, is taken from one body part and transplanted to another, often to cover damaged or missing skin. [12] Before surgery, the location of the donor site would be determined, and patients would undergo anesthesia. [13]
Soon, the tall cryotherapy tank is filling with a cloud of super-chilled gas: evaporated liquid nitrogen, one of the coldest substances on Earth. “Okay,” the technician says. “Get in.”
Both cryosurgery and electrosurgery are effective choices for small areas of actinic cheilitis. Cryosurgery is accomplished by applying liquid nitrogen in an open spraying technique. Local anesthesia is not required, but treatment of the entire lip can be quite painful. Cure rates in excess of 96% have been reported.
Cryosurgery is an old modality for the treatment of many skin cancers. When accurately utilized with a temperature probe and cryotherapy instruments, it can result in very good cure rate. Disadvantages include lack of margin control, tissue necrosis, over or under treatment of the tumor, and long recovery time.
Cryotherapy is applied using ice, cold water, or gel packs, sometimes in specialized devices that surround the skin and surgical site (but keeps the surgical site clean). [27] Evidence from clinical trials regarding the effectiveness of cryotherapy is weak and because of this, the use of cryotherapy may not be justified. [ 27 ]
