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.任何圓形或不對稱傷口的閉合都可能導致皺起或組織過剩，稱為狗耳。了解狗耳形成的機制是促進適當治療的基本要求。文獻中已經報道了許多解決方案，但在所有情況下，矯正需要擴展疤痕和犧牲真皮神經叢。在這里，我們提出了一種新的狗耳矯正技術，使用三咬縫線，順序刺穿深筋膜平面和每只狗耳的邊緣，從而通過錨定過度突出的組織到深平面，使狗耳變平。三咬技術被證明是一種快速、簡單和通用的方法，可以立即糾正狗耳朵，而不會擴大疤痕，同時保持充分和完整的局部皮膚血液供應。
