What method uses extreme cold for the destruction of lesions of the vulva?

Cryosurgery is the method that utilizes extreme cold for the destruction of lesions on the vulva. This technique involves the application of liquid nitrogen or other cryogenic substances to freeze and thus destroy abnormal tissues, such as lesions or warts. The extreme cold causes cellular injury and ultimately leads to cell death, effectively removing the undesirable or abnormal growths.

The precision of this technique allows for targeted treatment while minimizing damage to the surrounding healthy tissue. It is particularly useful for treating various skin lesions due to its effectiveness and the relatively low risk of scarring.

In comparison, electrosurgery uses electrical currents to cut or coagulate tissues, while laser surgery employs focused light energy, and brachytherapy involves placing radioactive sources close to or inside the area requiring treatment. Each of these techniques has its own applications, but when it comes to using extreme cold specifically, cryosurgery is the method of choice.
