Suction Blister Grafts
Suction blister epidermal grafting is a low-cost, highly-effective procedure that achieves full repigmentation in 68–70% of instances. The roof is surgically removed and transplanted to the recipient site after a subepidermal bulla is created from the donor site by continuous vacuum application.
Suction blister grafting
Negative pressure is applied to the usually pigmented donor site in suction blister grafting to encourage the production of numerous blisters.
Blisters may be raised using one of the following options:
- Suction pump
- Suction cups
- Negative pressure cutaneous suction chamber system
Vaseline is put to the bases of 10 ml and 20 ml syringes before they are used on the donor site. Blisters commonly appear within 1.5 to 2.5 hours. The blister roofs (grafts) are surgically removed, cut to size and shape, and transplanted onto the prepared recipient site.
With minimal scarring on the donor site and cobblestoning on the recipient site, good cosmetic results can be attained. Suction blister grafting is a relatively safe, simple, and economical procedure with a high success rate. It is, however, time demanding and can only be conducted on limited regions of skin.
Adverse Effects of Suction Blistering Grafts
Complications of suction blister grafting are limited to:
- Hyperpigmentation of the donor site
- Graft rejection
- Depigmentation around the graft
