It is generally accepted that the formation of the blepharoplasty line is dependent on the presence of some fibers in the levator muscle and the upper eyelid skin, but the author goes beyond this and argues that the amount of subcutaneous soft tissue in the upper eyelid directly determines the view of having a blepharoplasty line. There are several interesting questions: 1. Why is no obvious fibrous connection found between the levator aponeurosis and the dermis of the eyelid skin? 2. Why is it possible to obtain a temporary lid line by pressure or lid patching? 3. Why do eyelids that are formed with a buried liner tend to disappear? 4. Why do some people get heavy eyelids by chance when they get older? 5. Why does the eyelid line have to be formed through the connection between the levator aponeurosis and the skin, but not through the connection with the orbicularis oculi muscle? 6. Why do some people who have had blepharoplasty before and then have upper lid surgery to remove the connection between the levator muscle and the skin still have a blepharoplasty? The author has done some surgery as if it were a fake surgery for double eyelids. It’s a case of cutting along the heavy eyelid line, removing some of the orbicularis muscle under the skin, then or removing some of the orbital fat, and then just sewing the skin on. In 48 cases, there was only 1 case where the eyelid line disappeared during the 1-2 year follow up period. Here are his answers to those questions: 1. In theory, but in practice it is very difficult. 2, It is possible to move the intraorbital fat or soft tissue upward by pressure or tape, so a heavy lid is formed. 3. The softening of the scar adhesions formed by the buried liner method causes the soft tissue to enter again between the levator aponeurosis and the upper lid skin. This is why often the buried eyelid line disappears after 1-2 years. 4. The intraorbital fat tissue or the soft tissue between the levator muscle and the skin has atrophied and the amount of tissue has decreased. 5, It is true that the blepharoplasty line can be formed by establishing a connection between the levator aponeurosis and the orbicularis oculi muscle. 6. It is clear that the fixation of the levator aponeurosis and the skin is not necessary for blepharoplasty, and that the reduction in the amount of tissue at the blepharoplasty line after the previous surgery is the primary cause.
