Lower eye bags are a well-known manifestation of aging under the eyes for almost everyone, but below the protruding fat of the lower eye bags, an oblique sunken groove can usually be observed. This groove is the tear trough, which is now receiving increasing attention from doctors and patients. At the same time, the treatment of the tear trough has largely overturned traditional lower eyebag surgery, making lower blepharoplasty a much more refined and rational procedure. When tear troughs are present, patients usually feel a shadow under their eyes. This is especially noticeable when light shines on the eye from a specific angle. The presence of tear troughs also adds to the feeling of prominence of orbital septal fat and aggravates the appearance of aging under the eyes. There are several methods of tear trough treatment, each with its own characteristics: 1. Hyaluronic acid filling tear trough Advantages: simple and convenient. There is no recovery period. Immediate effect after injection, does not affect work and study. Disadvantages: the maintenance time is short, about six months to a year. The cost is relatively expensive. 2.Autologous fat transplantation to fill the tear trough Advantages: autologous tissue, no foreign body effect. The effect can be maintained for a long time after the fat becomes viable. Disadvantages: It may be necessary to repeat the injection several times, and the local area is easy to be uneven, the operation is tedious and there are more complications. 3.Surgical filling of tear trough (i.e. lower eye bags orbital fat release transfer surgery) Advantages: once completed, the effect is maintained for a long time. Safe and effective. Disadvantages: for patients with insufficient amount of orbital septal fat, other auxiliary treatments are required. In short, there are various ways to treat the tear trough, and the specific method to be used needs to be considered in conjunction with their own situation.
