Which procedure destroys tissue by burning with an electric spark?

Electrodesiccation is the procedure that effectively destroys tissue by using an electric spark to generate heat, which in turn causes tissue to dry out and be ablated. This technique is commonly used in dermatologic surgeries for the removal of warts, tumors, and other skin lesions. The electric current is precisely applied, allowing for controlled destruction of the targeted tissue while minimizing damage to surrounding structures.

In the context of this procedure, the utilization of an electric spark makes it distinct from other options, which do not involve this specific method of tissue destruction. Exudative refers to fluid that leaks from blood vessels into the surrounding tissues, which is unrelated to tissue ablation. Keratolytic refers to substances or processes that break down keratin in the skin, primarily used in treating conditions like acne or psoriasis, but it does not involve tissue destruction through burning. Keratosis describes a condition where there is an overgrowth of keratin on the skin, and while it may require treatment, it does not itself refer to a procedure for destroying tissue.

Thus, electrodesiccation stands out as the correct procedure that employs electricity to safely and effectively remove tissue through thermal destruction.
