In spite of the availability of high-tech devices for wound assessment, plastic surgeons recognize that the color and confluence of granulation tissue are the most important Indicators of open-wound healing. We developed a simple and inexpensive pocket-size scale - the Granulometer - to facilitate a finer assessment and to standardize the documentation of wound healing. This device overcomes limitations set by conditions such as lighting or recent exposure to other wounds that could distort the examiner's perception of the wound in question. In this study we examined the inter- and intraobserver variations in judgment, and the validity of the Granulometer. Our results demonstrate that skin graft viability can be predicted accurately by this eight-grade scale. Since graft survival depends on proper wound healing, we believe that the Granulometer can also be used for fine assessment of wound treatment. The low inter- and intraobserver variations indicate that the Granulometer measurements are both reproducible and accurate.
