[A new classification for standardizing nomenclature in wound closure by microvascular flap-plasty]

The profusion of terms currently used to describe microvascular flap wound closure according to the time of reconstruction makes reliable comparisons of outcomes between institutions difficult if not impossible. To address the issue, a consistent terminology applicable to microvascular flap wound closure in general was formulated with respect to our experience with a total of 197 microvascular tissue transplantations. The nomenclature presented divides microvascular flap closure into three categories: "primary microvascular flap closure" (within 24 hours). "delayed primary microvascular flap closure" (two to seven days), and "secondary microvascular flap closure" (after seven days). This is consistent with known biological, microbiological, and surgical principles of wound closure in general and should provide a simple basis for classifying microvascular flap wound closure. Sample cases are selected to illustrate the categories within this new classification scheme.
