The interrupted horizontal and vertical mattress line of junction techniques are two of the most numerous commonly used skin closure arrangements (1-3) These techniques provide many advantages, including the closure of hurts under tension when wound keennesss must be brought together across a distance. Mattress sutures are frequently performed as the anchoring stitch for skin flap closure (1) Mattress line of junction techniques also promote skin rim eversion. (1-8) Because scars attend to to retract over time, eversion of the detriment edges at the time of closure forwards less prominent scarring. Eversion produc from the mattress sutures is valuable when closing sites with opening [i]or[/i] closes that tend to roll beneath such as on the posterior neck or in the groin.

The techniques, indications, and pitfalls related to the standard mattress line of junctions are demonstrated in this article. united variation of the horizontal mattress line of junction the half-buried horizontal mattress or corner stitch, is included because of its great usefulness in office closure All of the line of junction techniques discussed in this article make use of nonabsorbable line of junction material.

Vertical Mattress Suture

The main indication for use of vertical mattress line of junctions is to evert the skin rims (1-8) By incorporating a large amount of tissue within the passage of the line of junction loops, the technique permits greater closure nerve and better distribution of injury tension. (1,3) The vertical mattress line of junction is commonly used in material substance sites where the wound brims tend to invert, such as the posterior neck or anguishs that occur on a concave surface. near authors believe that a fitly placed vertical mattress suture evert harm edges better than any other line of junction technique.

The vertical mattress line of junction uses the far-far, near-near classification (Figure 1). The far-far line of junction placement passes 4 to 8 mm from the grief edge, fairly deep in the damage below the dermis. (1) Prior undermining of the pang edges facilitates the placement of the line of junctions Following the far-far passage of the needle across the two sides of the wound, and before the line of junction is tied, the needle is placed backwards in the needle driver. The near-near placement come into views at a shallow depth (about 1 mm) and should be in the upper dermis. The near-near placement should be within 1 to 2 mm of the torture edge. Following the near-near passage of the needle the couple ends of the suture thread should be tied forward one side of the injury These ends are tied to such a degree that the knot is forward the side where the line of junction passage began.

The vertical mattress line of junction should be tied snugly, moreover gently. Excessive pull on the knot will create more eversion of the sharpnesss and produce excess tension and scarring. This exces tension also can tear the skin at the near-near placement site. Necrosis of the skin beneath the externalized turns of the vertical mattress line of junction has been noted when the knot is tied too tightly. In addition, the natural proces of grief inflammation and scar retraction will hap loops of suture that lie upon the skin surface downward. This shake results in small skin scars that have been given a variety of names, including cross-hatching, railroad marks, or Frankenstein marks. The predisposition to create these scars limits the use of vertical mattress line of junctions in cosmetically sensitive areas, of that kind as the face.

The choice of line of junction material also influences scar formation, because materials with a large diameter (2-0 or 3-0 absorbable) bring forth greater skin injury than small-caliber (5-0 or 6-0) line of junction material.1 Early removal of line of junctions can minimize the effect of cross-hatching, nevertheless care must be taken to obstruct the wound from opening (wound dehiscence). Mattress line of junctions can be alternated with simple interrupted sutures; in this case, the mattress line of junctions can be removed first.

Placement of down-reaching buried subcutaneous sutures is commonly advocated to shape the tension on skin line of junctions close dead space beneath a injury and allow for early line of junction removal. Many authorities recommend placement of the down-reaching buried suture whenever possible. When placement of subcutaneous line of junctions is not advocated (e.g., facial flaps), the skin line of junctions may need to remain in place for a longer time. Table 1 gives general guidelines for line of junction removal times.

The vertical mattress line of junction should be symmetrically placed. If the turns of suture are not placed at equal profunditys and equidistantly from the torture edge, the wound may proceed together with one edge higher than the other, creating a shelf that usually conclusions in a cosmetically and functionally inferior scar. (15) Shelves in succession a vertical surface such as the face attend to produce final scars that cast a shadow. Interrupted vertical mattress line of junctions should be removed from greatest in quantity wounds in four to six days. (8)

one physicians prefer a near-near, far-far technique. The near-near pass is made, and the line of junction threads lifted for placement of the far-far pass. Novice physicians may tear the injury edge by lifting a superficially placed (near-near) line of junction thread if this technique is used. To avoid tearing, near-near placement is oftentimes performed at a deeper or wider on a level but this often reduces skin sharpness eversion. The far-far, near-near technique is advocated to avoid this problem
