Procedures Performed by Dermatologists

Dermatologists in India are trained in performing various procedures to diagnose, treat, and manage dermatological conditions. Here are some common procedures performed by dermatologists:

Electrosurgery

Electrosurgery involves the surgical use of a high-frequency electric current to cut, coagulate, or remove tissue. Dermatologists may utilize electrosurgery for procedures such as removing skin tags, warts, or benign lesions, as well as for electrodessication of certain skin growths.

Cryosurgery

Cryosurgery involves the use of extreme cold, typically using liquid nitrogen, to freeze and destroy abnormal or unwanted tissue. Dermatologists commonly employ cryosurgery to treat conditions like warts, actinic keratoses (precancerous skin lesions), and some types of skin cancers.

Laser surgery

Dermatologists use laser surgery for various purposes, including skin resurfacing, tattoo removal, scar reduction, hair removal, and treatment of vascular lesions like birthmarks or spider veins. Different types of lasers are employed depending on the specific condition being treated.

Excision surgery
