Maceration of a surgical wound occurs when excessive moisture is trapped beneath the dressing, leading to the softening and whitening of the surrounding skin. This condition impairs the normal wound healing process by breaking down the epidermal barrier and increasing the risk of infection. Proper wound management requires dressings that allow adequate ventilation and moisture control to prevent accumulation of exudate or sweat. Maceration differs from infection or mechanical pressure and is primarily a consequence of prolonged exposure to moisture under occlusive dressings. Hence, controlling moisture balance is essential to avoid maceration and promote optimal wound healing.
