Corner Sutures Minimize Tissue Ischemia
Corner sutures are an underutilized technique for primary wound closure. They have multiple benefits compared with using simple interrupted sutures to close lacerations shaped like a V or Y. They also minimize tissue ischemia to the flap tip, lowering the risk for tissue necrosis and a poor cosmetic outcome. It also “pulls” the flap tip snugly in place, minimizing a potential wound gap.
Have a problem with the laceration knot sitting atop the flap tip? Here are pro tips: Position the laceration so that the flap tip appears as a V from your perspective. Draw an imaginary horizontal line through where the flap tip will be approximated. Start and end your suture inferior to this horizontal line.
