What is a tensile reducing suture? What are the effects on postoperative scarring?

Tension reduction suture reduces the incision suture tension. The sutures for clinical** sutures are usually closed using a one-line suture. Tension reduction sutures are performed using 10 threads from the peritoneum.

Outer will ** subcutaneous tissue.

The muscles are sutured in full thickness to reduce the tension of the wound and thus ensure the healing of the tissue. Generally, it is suitable for patients with severe abdominal infections and large tissue tension. Or the patient is poorly nourished, accompanied by hypoproteinemia, ascites.

As a result, the intra-abdominal pressure is relatively high, or the patient has serious cardiopulmonary disease, and the ordinary suture tension is relatively small. In patients present with a severe cough.

Increased intra-abdominal pressure caused by sneezing or large amounts of ascites may cause the incision sutures to break and cause the incision to dehisce. Tension-reducing sutures usually take 14 days to remove the stitches. <

Tension-reducing sutures are mostly used in plastic surgery and general surgery.

Surgery. With tensile-reducing sutures, when the wound is sutured, the wound dehiscence tension is released in the subcutaneous layer, and when suturing, the layer does not dehisce due to tension, and does not leave a scar when healing.

The aesthetic results will be better after surgery. The concept of tension-reducing sutures is more important in plastic surgeons. Compared with plastic surgery, tension-reducing sutures may be more common in general surgery, rather than layer-by-layer sutures.

Instead, a larger needle and thread are used to penetrate the ** and subcutaneous tissues throughout the whole process, and the injured skin margins on both sides are pulled together for suturing. And the wound dehiscence tension is evenly distributed under the skin and at the ** level, in the ** healing process, ** bear the wound dehiscence tension, and the wound scar will be wider and more obvious after healing, and it may bulge and form a centipede-like scar. Compared with the reduction suture, the suture is more delicate, and the postoperative suture effect will be more beautiful.

Tenoplastic sutures. The biggest advantage is that the tension is small, and it will not crack due to swelling. It heals without scarring. When applied to facial plastic surgery, some scars are very small and not easy to see. <

As the name suggests, tension reduction suture is a type of suture that reduces the tension of the incidelion, so the needle is deeper and more forceful in order to reduce the tension of the wound.

Scar impact: 1. There will still be scars after this surgery, which need to be removed with a laser.

2. The scar surgery process is long.

Full-thickness sutures or extraperitoneal sutures, i.e., sutures**, subcutaneous and muscular layers. It is to reduce muscle tension and prevent muscle hyperextension that can lead to tears.

This is a term commonly used by surgeons, and simply means that the dehiscence wound is compounded with a tension-reducing suture technique, allowing the subcutaneous tissue to withstand this tension. There is almost no effect on the postoperative scar, which is a new suture technique that leaves a negligible scar.

As the name suggests, tensile suture is a suture method used to reduce the tension of the incision. Generally, it is mostly used for users who are particularly emaciated, have poor constitution, and suspect that the incision will not heal normally after surgery, and may have incision dehiscence, and it is also used for users who have incision dehiscence, incision infection, and secondary surgery after surgery.

Hypotension sutures are generally full-thickness sutures or extraperitoneal sutures, i.e., sutures**, subcutaneous and muscular. The needle length of the suture is relatively wide, generally more than 2cm away from the incision, and the surface of the suture needs to be worn with a rubber tube, such as a red urinary catheter. Because the tension reduction suture routinely requires 14 days to remove the suture and the strength of the tension reduction suture is relatively large, it is possible that the thread knot will be cut into the **, so it should be protected with a rubber tube**.

Everyone wants perfect skin, many people feel inferior because they have unsightly scars on their bodies, and they will be discriminated against by others, so there are many people in life who will remove annoying scars through scar excision, so what are the disadvantages of scar excision and suture surgery?

The disadvantage of scar excision and suturing surgery is that patients with scar constitution are generally not suitable for scar resection.

Postoperative characteristics: It can be basically close to normal**, but the effect of scar excision surgery should be based on the individual's physique, and the effect of surgery is not the same depending on the physique. The superficial scar continues to increase, which not only affects the appearance, but also affects the functional movement of local pain, redness and itching, and scar contraction), and the effect of scar excision surgery will be poor.

Special reminder: Most patients are easily mistaken for thinking that as long as the doctor's medical skills are skillful, the scar can be removed completely without leaving a trace, but the scar excision surgery is only a reduction operation to reduce the original scar to the original state before the scar appears, and it is impossible to completely remove it. It's just a matter of reducing the width of the scar or shifting the direction of the scar to a wrinkle so that others don't notice it right away.

Scars vary depending on the cause, depth, direction, etc., which has an impact on the difficulty and outcome of the surgery.

Scar formation is very closely related to suturing techniques. There are many reasons for the formation of scars, such as personal constitution, race, injury location, timing, method and suture technique and other factors can affect scar formation, among them, the timing, method and suture technology are medical reasons, and the proper method will greatly reduce the formation of scars. Suturing techniqueFirst of all, the suture must be strictly aseptic, complete hemostasis and debridement, leave no dead space, and suture the tissues of the same layer with each other.

When the tension of the incision edge is large, it should be sutured with silk threads from the superficial fascia layer first, and the tension should be reduced layer by layer, and finally the epidermal layer should be completely tension-free. It mainly includes many factors such as suture method, suture material and suture tightness, which are related to the formation of scars.

1) Suture method: In different cases, different closed wound suture methods should be used, such as intermittent suture, mattress suture, intradermal interrupted suture, tension reduction suture, etc., in order to obtain the best healing and the smallest scarring. Among them, intermittent sutures can make the first wound margin fit neatly, and the height and thickness of the tissues on both sides of the wound margin tend to be consistent after adjustment, and it is conducive to sequential suture removal; The advantage of continuous suture is that it saves time, and the disadvantage is that it must be removed centrally; Mattress suture has the effect of increasing the amount of tissue in contact with the wound and reducing tension to a certain extent, so it is conducive to wound healing.

In order to avoid pinhole marks on the surface, intradermal suturing can be performed, and the epidermis is therefore self-aligned, which is called intradermal suture, and the surface can be externally reinforced with adhesive glue.

2) Suture material: There are two kinds of suture materials: absorbent and non-absorbent. At present, absorbable sutures are mostly gut threads, chrome gut threads and synthetic materials, and the advantage is that they can be absorbed by themselves without removing sutures after deep sutures, and the sutures made of synthetic fibers have good operability, strength and light tissue response.

Non-absorbing sutures, commonly used are silk threads, synthetic polymer nylon threads, polyester threads, etc., the latter two sutures are better, although they do not absorb but cause a very slight reaction in the tissue, currently commonly used. The thickness of the sutures should be selected according to the size and location of the wound tension, and usually the suture trauma caused by small needles and fine threads is small, and the scar reaction is of course small. At present, some scholars use biological and synthetic adhesive materials to replace sutures, which have a certain effect on the prevention of scar hyperplasia.

3) Suture tightness: ** Suturing requires moderate tightness, so that the wound is completely in contact and neatly aligned. Tightness, hinder the blood supply to the wound, is not conducive to healing, and enhances scar hyperplasia.

Insufficient strength, or loose knots that prevent the wound from being fully connected and neatly aligned, also affect healing and aggravated scarring.

The selection of surgical incision is very important for surgical scar, which is also an important topic in medicine, and the selection of a good surgical incision is not only conducive to the surgeon's operation, but also minimizes the formation of ** damage and surgical scar.

The choice of incision is related to the exposure of the surgical field, which is a prerequisite for surgery. The ideal incision should have access to and easy exposure of the surgical site, perfect geometry, appropriate length, easy opening and closing, minimal trauma and little blood loss.

Generally, a gripping or bow-holding scalpel is used. These two methods have a wide field of vision, can ** the entire path of the incision from the starting point to the end point, the movement is free, the amplitude is large, and it is suitable for cutting long incisions. The pen holding style is suitable for delicate cutting and dissection, but the field of vision is not wide enough, the predetermined cutting behavior is often blocked by the hand holding the knife, and it is necessary to pause to observe and correct the direction of the incision, which is prone to offset and pause, and the action is not stretched enough, so it is not suitable for larger cutting.

It is also not conducive to the formation of small surgical scars.

The scalpel is incised at 45° to the tissue plane and the blade is perpendicular to the abdominal wall, so that the two edges of the incut are symmetrical. The surgeon and assistant should use symmetrical force to pull the tissue, otherwise the incision will bend to the contralateral side of the overtraction. The lower part of the straight incision is often bent to the side of the surgeon because the elbow is always bent inward.

To make a straight incision, it is necessary to overcome this innate inclination. The incised layers of the abdominal wall should be in the same plane. This requires that the abdominal wall be incised vertically, otherwise the layers of the abdominal wall of the incision will be shifted.
