The closure of any circular or asymmetric wound can result in puckering or an excess of tissue known as a dog ear . Understanding the mechanism of dog ear formation is a fundamental requirement necessary to facilitate an appropriate treatment. Many solutions have been reported in the literature, but in all cases, the correction entails the extension of the scar and the sacrifice of the dermal plexus. Here, we propose a novel technique of dog ear correction by using a three-bite suture that sequentially pierces the deep fascial plane and each dog ear s margin, thus allowing for flattening the dog ear by anchoring the overprojecting tissue to the deep plane. The three-bite technique proved to be a fast, easy, and versatile method of immediate dog ear correction without extending the scar, while maintaining a full and complete local skin blood supply.任何圆形或不对称伤口的闭合都可能导致皱起或组织过剩，称为狗耳。了解狗耳形成的机制是促进适当治疗的基本要求。文献中已经报道了许多解决方案，但在所有情况下，矫正需要扩展疤痕和牺牲真皮神经丛。在这里，我们提出了一种新的狗耳矫正技术，使用三咬缝线，顺序刺穿深筋膜平面和每只狗耳的边缘，从而通过锚定过度突出的组织到深平面，使狗耳变平。三咬技术被证明是一种快速、简单和通用的方法，可以立即纠正狗耳朵，而不会扩大疤痕，同时保持充分和完整的局部皮肤血液供应。
