Abstract
Negative-pressure dressings have been used in the treatment of a variety of open wounds, and as a bolster for skin grafts. The benefits of these dressings include increased oxygen tension in the wound, decreased bacterial counts, increased granulation formation, and the prevention of shear force on wounds. Also, by virtue of the diminished need for daily dressing changes, there are the additional advantages of enhancing patient comfort, decreasing nursing work, and diminished cost of wound care. Hidradenitis suppurativa (HS) is a chronic infection of the apocrine sweat glands. Treatment options range from oral isotretinoin to radical excision. Wound closure may be achieved by secondary intention, skin grafting, or flap closure. Complications may still arise and include disease progression and squamous cell carcinoma. Radical excision yields the best results in terms of disease eradication. The authors describe using the negative-pressure dressing in two cases of bilateral axillary HS to secure skin grafts firmly to the wound bed after radical excision of all involved tissues. Patient comfort and acceptance was high, and skin graft take was excellent. The dressings themselves are simple to apply and are highly effective.
