The tear trough, though small in physical dimensions, sits at the perceptual epicenter of the face. Because small changes here make large changes in how other people interpret one's state of being, it would be beneficial to have a simple way of addressing the area. Despite the complexities of cause, the solution is to level the hollow and smooth the junction between the lid and the cheek.
Hyaluronic acid injections are used to address the tear trough deformity. Very small quantities, 0.2 to 0.4 cc, are used per side, and the placement is in the orbicularis oculi muscle or at the periosteum. The key is to inject deep to the dermis and to massage the injected area smooth.
All patients were improved roughly in proportion to their skin quality. The best patients for the treatment are those with young, thick skin and a definite hollow. The duration of the effect is often more than 1 year at this location. Minor bruising and irregularities were self-limiting or treated with light massage. Large overfills or irregularities are correctable with injection of hyaluronidase.
Tear trough injection with hyaluronic acid products is relatively simple, effective, and safe, and can offer significant improvement in this difficult area. It can be performed for primary deformities or to improve a surgical result.
泪沟虽然在生理尺寸上较小，但却位于面部的感知中心。因为这里的微小变化会在很大程度上改变他人对一个人状态的解读，所以拥有一种简单的方法来处理这个区域会很有帮助。尽管病因复杂，但解决办法是填平凹陷并使眼睑与脸颊之间的交界处变得平滑。
使用透明质酸注射来解决泪沟畸形问题。每侧使用非常少量的透明质酸，即0.2至0.4立方厘米，注射部位在眼轮匝肌或骨膜处。关键是要在真皮深层进行注射并将注射区域按摩至平滑。
所有患者的改善程度大致与他们的皮肤质量成比例。最适合该治疗的患者是那些皮肤年轻、厚实且有明显凹陷的人。在此部位，效果的持续时间通常超过1年。轻微的瘀伤和不平整会自行消退或通过轻度按摩进行处理。大量填充过度或不平整可通过注射透明质酸酶进行纠正。
用透明质酸产品进行泪沟注射相对简单、有效且安全，并且可以在这个棘手的区域带来显著改善。它可用于原发性畸形或改善手术效果。
