Many of my friends who come to me for scar excision ask me after surgery why the skin at the suture site is raised after the use of hyper-reduced tension fine sutures. In other words, what is hypertonic fine suture. Ultra-decreasing fine suture is to make a distant anchor point in the dermis and then use suture to make a deep suture, which is very particular about the site and level of the incoming suture, the route of the thread in the tissue, the site and level of the outgoing suture, the tightness of the thread knot and the distance between the stitches, and the distance between the edges. These threads, on the other hand, are even more delicate. Generally, 3-0# absorbable sutures are used in the muscle layer, 5-0# absorbable threads are used in the subcutaneous tissue layer, and 6-0# or 7-0# non-absorbable sutures are used in the skin layer. With this type of suture the skin on the surface of the suture will be easy to lean together and in the body epidermis so that he protrudes a part of the bulge, with the extension of time, the bulge slowly flatten, but the wound will not be stretched wider. Many people do not understand, thinking that the skin bulge is a sign of suture failure, in fact, is not, this bulge, precisely the key to reduce tension, it can be said that the longer the bulge, the better the final result. Therefore, the bulging of the skin surface after suturing is the most significant feature and the biggest advantage of the hypertonic fine suture. The recovery of a wound closed in this way is a very fine line, and with proper aftercare, it is very inconspicuous from a normal social distance. At present, the ultra-reduced tension fine suture technique has been widely used in small scar excision, small tattoo excision, nevus excision and other high requirements for the recovery of the appearance of the patient’s satisfaction is high, the postoperative effect is remarkable, in some of the need for suture in the operation has been gradually replaced by the past traditional surgical suture.
