Depending on the degree of strain and the size of the defect, healthexperts most usually employ the figure of 8 sutureto either diminish or eliminate a defect.
This is a strategy modification for smaller flaws known as the "purse-string approach."
The amount of strain applied to the purse string, together with the size of the imperfection, determines the outcome of this approach, which is similar to the traditional purse-string method in that it may either reduce the size of the defect or eliminate it.
It is a specialized method because it causes a slight puckering in the skin immediately surrounding the treated area.

  • Step 3:Begin the suture in the vicinity of one of the positioning lines on the far side of the laceration on the imitation skin. With the tissue forceps, evert the far side of the laceration and insert the needle between five and ten millimeters (approximately a quarter inch) away from the wound edge.
  • Step 4:Insert the needle into the subcutaneous tissue on the near side, twisting it so that the needlepoint emerges just below the dermis.
  • Step 5:Mirror the bite on the other side, enabling the needle to emerge in the depths of the subcutaneous tissue.
  • Step 6:Insert the last piece of the suture into the tissue on the near side, just below the dermis, with the needle pointing up. Allow the needlepoint to emerge three millimeters distant from the wound's edge on the near side.
  • Step 7:Tie a surgeon's knot or an instrument square knot. Leave at least three millimeters of suture material beyond the knot on both ends of the suture.
  • Step 8:Repeat Steps 4 and 5 to place a second figure-8 suture approximately three millimeters to the right of the first stitch.
  • Step 9:Continue to use figure-8 sutures to seal the wound. When everything is said and done, this is the suture's course. In the top left, then the bottom right, then the bottom left, and finally the top right.
