Cryotherapy
Cryotherapy is the targeted use of extreme cold to destroy unhealthy or unwanted tissue. The doctor applies the cold on the skin or injects it through a needle to reach the inside of the body, where it freezes away the problem tissue. Cryotherapy is often used to remove minor skin problems such as warts or skin tags, and it is also used to treat some small tumors.
To achieve the cold temperatures needed for cryotherapy, liquid nitrogen or argon gas is passed through a tube, which becomes cold enough to freeze cells on contact. Alternatively, liquid nitrogen can be swabbed directly onto the skin or via a spray, which applies only a specific, small amount to the skin at a time.
Because the area treated is typically very small, cryotherapy is not usually painful. There may be a sensation of cold and possibly some slight discomfort. Cryotherapy is very fast and can easily be performed in a doctor's office. It also doesn't require stitches, because there is no cutting involved. These benefits make cryotherapy a good choice for many issues, including:
Depending on the procedure, it usually takes three to four weeks to heal after cryotherapy. If it was done internally, patients may feel sore or have a small amount of swelling the first day afterwards. If cryotherapy was performed on the skin, patients will have a scab where their tissue was removed. Keep it clean and dry so it can heal.
Debridement (Removal of Unhealthy Tissue)
Debridement is a procedure that removes damaged skin to help the body heal a chronic wound, acute injury, or burn. Several layers of skin surrounding a chronic wound can include foreign debris, dead (necrotic) tissue, infected tissue, and calloused (hyperkeratotic) skin. If left untreated, these damaged skin layers can spread infection to other parts of the body and may aggravate the wound and delay its healing.
Debriding (removing) this damaged and diseased skin encourages the growth of healthy new tissue, impeding infection by triggering the body's natural cycle of tissue renewal. For this reason, debridement functions both as a wound treatment and as a preventative measure against more complex consequences of infected skin, such as sepsis and amputation. In some circumstances, debridement provides additional aesthetic benefits such as decreased scarring. Debridement also permits doctors to retrieve tissue samples for testing, such as to determine whether patients need antibiotic treatment.
Wounds that frequently require debridement include:
Debridement can be performed either surgically or nonsurgically; some methods are less invasive than others. Doctors select the appropriate debridement technique by considering the location, cause, and size of a patient's wound and may also weigh the patient's overall wellbeing, age, and risk of infection.
Surgical debridement is performed by cutting away dead, infected, and hyperkeratotic skin with a surgical scalpel. For deep wounds that tear away the skin and go into the muscle, skin from another region of a patient's body may be grafted onto the wound, which may then be periodically assessed and rebandaged until fully healed.
Non-surgical debridement is achieved with water or a dissolvent gel. Water softens the damaged skin and affected tissue, allowing doctors to remove it with wet-to-dry dressing. When wet tissue dries, it adheres to the dry dressing or bandage and comes off when the dressing is pulled away. In contrast, dissolvent gel deconstructs tissue, which can be cleaned off of the wound. Nonsurgical debridement is less invasive than surgical techniques; however, it can entail repeat treatments, slowing wound recovery.
While the prospect of stripping away skin may seem jarring, debridement can be critical to the treatment and healing of wounds which cannot not heal independently.
