In general, women start to have sagging skin on the upper and lower lids after the age of about 30, gradually forming “triangular eyes” and eye bags, and fishtail lines on the outer canthus. 35 to 40 year old women can have mild sagging eyes, fishtail lines and eye bags. After the age of 40, eyelid skin laxity increases, lines deepen, and wrinkles begin to appear between the eyebrows and forehead and gradually worsen. If you have these signs of aging, what should you do if you do not want to undergo extensive wrinkle reduction, but still want an effective procedure with a hidden incision? Can you accept the “serrated small incision wrinkle reduction with hair follicle preservation at the temporal hairline”? It is very effective in reducing crow’s feet, and also has a good effect on cheek sagging and decrepit lines (nasolabial folds) wrinkles, and it is less traumatic, quick recovery, and precise results. Let’s look at the incision first: it is along the hairline design serrated line oblique forward in a 40 ° ~ 45 ° cut the skin to the subcutaneous, retaining part of the hair follicle at the hairline margin. The skin is then incised 40°~45° forward inward to the subcutaneous area according to the distal design line, the flap is excised, the SMAS is separated on the subcutaneous area to the design area, and electrocoagulation is performed to completely stop bleeding. Suspension and fixation: 2~3 stitches of 4-0 absorbable thread were used to suspend the orbicularis oculi muscle in the external canthus with radial pulling sutures to stretch the orbicularis oculi muscle; SMAS fascial lifting and folding sutures were used to fix the lax cheek area. Suture: When closing the incision, first use 4-0 absorbable thread horizontal mattress suture to make the tension moderate, and then use 6-0 nylon thread to perform external suture.
