[involves application of an extremely cold chemical (eg: liquid nitrogen)]
dermabrasion
surgical removal of frozen epidermis using wire brushes & emery papers to remove scars, tattoos, and/or wrinkles
[aerosol spray is used to freeze skin]
debridement
removal of dead tissue from a wound or burn site to promote healing & prevent infection
curettage
to clean; scraping of a wound using a spoon-like cutting instrument
[called a curette; this technique is used in debridement]
electrosurgical procedures
use of electric currents to destroy tissue
electrosurgical procedures:
1- electrocautery
use of instrument heated by electric current (cautery) to coagulate bleeding areas by burning the tissue
(eg: to sear blood vessel)
electrosurgical procedures:
2- electrodesiccation
use of short, high-frequency, electric currents to destroy tissue by drying
[--active electrode makes direct contact with skin lesion

[an instrument that concentrates high frequencies of light into a small, extremely intense beam that is precise in depth & diameter; it is applied to body tissues to destroy or for dissection (cutting of parts for study)]
Mohs surgery
technique used to excise tumors of the skin by removing fresh tissue layer by layer until tumor-free plane is reached
skin grafting
transfer of skin from one body site to another to replace skin lose through burns or injury
skin grafting:

transfer to a new position in body of same person
skin grafting
2- homograft (allograft)
donor transfer between indviduals of same species
[such as human to human (homo=same)(allo=other)]
skin grafting
3- xenograft (heterograft)
graft transfer from one animal species to one of another species
(xeno=strange) (hetero=different)
