What is thiersch skin graft?

The Thiersch graft is essentially a partial-thickness, semitransparent skin graft that is used to re-epithelialize portions of a newly created mastoid cavity or a surgically altered external auditory canal. This highly effective technique allows for a significantly shorter postoperative recovery time.

What is tissue cultured skin?

Abstract. Current tissue-culture techniques enable keratinocytes from a small piece of skin to be grown into sheets of epithelium, or cultured keratinocyte grafts, that are suitable for treating wounds.

What is skin meshing?

Meshing involves running the donor skin through a machine that makes small slits that allow expansion similar to fish netting. In a meshed skin graft, the skin from the donor site is stretched to allow it to cover an area larger than itself. Healing occurs as the spaces between the mesh fill in with new skin growth.

When does vitiligo get stable?

Stable vitiligo was defined as having no new lesions and no progression of existing lesions for at least 2 years, while unstable vitiligo was defined as new lesions or progression of existing lesions over the past 6 weeks.

What is a full-thickness skin graft?

Full-thickness skin grafts (FTSGs) consist of complete epidermis and dermis, whereas partial-thickness skin grafts (PTSG) include the entire epidermis and only partial dermis. One should try to match, as closely as possible, the skin at the recipient site.

Is artificial skin available in medicine?

There are several synthetic skin substitutes available for wound coverage commercially. These include Biobrane®, Dermagraft®, Integra®, Apligraf®, MatriDerm®, OrCel®, Hyalomatrix®, and Renoskin® (Halim et al., 2010).

What is a full thickness skin graft?

Where is cadaver skin from?

Cadaver skin is removed from donors shortly after their deaths, then processed and distributed by skin and tissue banks. It has long been the preferred option for a patient with the most severe burns until a graft of the patient’s own skin can be applied.

What are the four types of skin grafts?

Free skin grafts for soft tissue reconstruction can be classified into four types: full-thickness skin grafts, split-thickness skin grafts, composite grafts, and free cartilage grafts. The indications, techniques, donor site considerations, and postoperative complications of each type of skin graft are reviewed.

How long does vitiligo stay active?

It spreads very quickly, faster than the other forms, but only for about 6 months (sometimes up to a year). It’s such a rapid pace that patients assume it will soon cover their entire body, but it stops abruptly and usually remains stable, without changing, forever after that.

How do you know if vitiligo is active?

Reported clinical signs in relation to active vitiligo were as follows: Koebner’s phenomenon, confetti-like depigmentations, tri- and hypochromic lesions (including poorly defined borders), inflammatory borders/areas, itch and leukotrichia.
