RESUMO
Until recently, military personnel have had the greatest risk for cold injuries. During the past two decades, however, destitute persons without adequate clothing or shelter, and sports enthusiasts participating in snowmobiling, mountain climbing, and skiing have been responsible for the increased incidence of cold exposure seen in a large civilian population. Consequently, cold injury remains a crippling problem. Although research is opening new avenues of accurate diagnosis and expeditious treatment, the standard against which these methods must be measured continues to be a rational treatment plan that often prevents the sequelae of cold injuries.

Large disposable circular trephines have been developed specially for circular excision biopsy of the skin. This technique is a simple and practical alternative to the traditional method of excision. It has the advantages of aligning the incision in the direction of the maximum skin tensions and reducing the length of the final wound closure.
