a technique for restoring wrinkled, scarred, or blemished skin by applying an acid solution to "peel" away the top layers of the skin

2

cryosurgery

destruction of tissue by freezing with application of an extremely cold chemical (e.g., liquid nitrogen)

3

dermabrasion

surgical removal of the epidermis frozen by aerosol spray using wire brushes and emery papers to remove scars, tattoos, and/or wrinkles

4

debridement

removal of dead tissue from a wound or burn site to promote healing and to prevent infection

5

curettage

cleaning; scraping a wound using a spoon-like cutting instrument called a currette; used for debridement

6

electrosurgical procedures

use of electric current to destroy tissue; the type and strength of the current and method of application vary

7

electrocautery

use of an instrument heated by electric current (cautery) to coagulate bleeding areas by burning the tissue (e.g., to sear a blood vessel)

8

electrodesiccation

use of high-frequency electric currents to destroy tissue by drying it; the active electrode makes direct contact with the skin lesion (desiccate = to dry up)

9

fulguration

to lighten; use of long, high-frequency, electric sparks to destroy tissue; the active electrode does not touch the skin

10

incision and drainage (I & D)

incision and drainage of an infected skin lesion (e.g., an abscess)

11

laser

12

laser surgery

surgery using a laser in various dermatologic procedures to remove lesions, scars, tattoos, etc.

13

Mohs surgery

a technique used to excise tumors of the skin by removing fresh tissue, layer by layer, until a tumor-free layer is reached

14

skin grafting

transfer of skin from one body part to another to replace skin that has been lost through a burn or injury

15

autograft

graft transfer to a new position in the body of the same person (auto = self)

16

heterograft; xenograft

graft transfer between different species, such as from animal to human (hetero = different, xeno = strange)

17
