DIAGNOSTIC TECHNIQUES, TREATMENTS AND PROCEDURES Integumentary System

Diagnostic Techniques, Treatments, and Procedures Allergy testing – Various procedures used to identify specific allergens in an individual by exposing the person to a very small quantity of the allergen Cautery – Heat or caustic substances that burn and scar the skin

Diagnostic Techniques, Treatments, and Procedures Cryosurgery – Noninvasive treatment that uses subfreezing temperature to freeze and destroy tissue Curettage and electrodesiccation – Scraping away of abnormal tissue, followed by destroying the tumor base with a low-voltage electrode

Diagnostic Techniques, Treatments, and Procedures Debridement – Removal of debris, foreign objects, and damaged or necrotic tissue from a wound in order to prevent infection and promote healing Dermabrasion – Removal of the epidermis and a portion of the dermis with sandpaper or brushes in order to eliminate superficial scars of unwanted tattoos

Dermatoplasty – Skin transplantation to a body surface damaged by injury or disease Electrodesiccation – Technique using an electrical spark to burn and destroy tissue – Also known as fulguration Diagnostic Techniques, Treatments, and Procedures

Electrosurgery – Removal or destruction of tissue with an electrical current Escharotomy – Incision made into the necrotic tissue resulting from a severe burn

Diagnostic Techniques, Treatments, and Procedures Liposuction – Aspiration of fat through a suction cannula or curette to alter the body contours Skin biopsy – Removal of a small piece of tissue from skin lesions for examination under a microscope to confirm or establish a diagnosis

Diagnostic Techniques, Treatments, and Procedures Skin graft – Process of placing tissue on a recipient site, taken from a donor site, in order to provide the protective mechanisms of skin to an area unable to regenerate skin Wood’s lamp – Ultraviolet light that is used to examine the scalp and skin for the purpose of observing fungal spores
