Electro cauterization is a surgical procedure that involves the use of electricity to administer heat to a section of tissue. The procedure is recommended for several reasons including prevention of bleeding after an injury or during surgery, removal of abnormal tissue growth and prevention of infections. Electro cautery treatment is generally performed under a general anesthesia. The doctor will use the specialized instrument to administer a mild electric current to the affected tissue. The heat from the instrument seals the blood vessels and cuts off the indicated tissue. Besides various medical applications, electro cauterization can be used for cosmetic considerations. Electro cautery treatment is often recommended for the removal of warts. Warts in any part of the body can distort the appearance of an individual and therefore can be distressing. Facial warts can be particularly irksome as they are easily noticeable and invite reactions and comments. Medications like salicylic acid advised for facial warts as their strong chemical composition and abrasive action may lead to scarring. The most suitable course of treatment for facial warts is electro cauterization. The heat from the instrument gently removes the abnormal tissue, seals the blood vessels of the affected area and sterilizes the site. Stitches are not required. Complete recovery usually takes place within two to four weeks. However, it may depend on the size of the area treated and the amount of tissue removed. Mild side effects may include slight bleeding, infection, pain or mild discomfort. The treatment is not advised for individuals using a pacemaker or prosthetic joint.
