Others modified this shield and began using instruments that produced a crushing action. Still used in many parts of the world, bone cutters are used to shield the glans, crush the foreskin tissue and guide the scalpel for a clean incision. The Mogen clamp is a refinement of these ancient techniques. [2]
The horizontal mattress stitch is a suture technique used to close wounds.It everts skin well and spreads tension along the wound edge. [1] [2] [3] This makes it ideal for holding together fragile skin [4] as well as skin under high tension such as the distant edges of a large laceration or as the initial holding suture in complicated repairs.
Other stitches or suturing techniques include: Purse-string suture, a continuous, circular inverting suture which is made to secure apposition of the edges of a surgical or traumatic wound. [13] [14] Figure-of-eight stitch; Subcuticular stitch. A continuous suture where the needle enters and exits the epidermis along the plane of the skin.
New knots have been described. Other commonly employed knots are surgeon's knot, modified surgeon's knot, single-double other side knot, strangle knot and modified miller's knot. The Surgeon's knot has been a standard ligature but in one study it demonstrated slippage. [4] While the suture is being put in place a knot is used to secure the suture.
Reconstructive surgery may be performed to restore what was lost, often with techniques similar to those used in gender-affirming surgery. [ 14 ] During childbirth , an episiotomy (cutting part of the tissue between the vagina and the anus) is sometimes performed to increase the amount of space through which the baby may emerge.
They tend to absorb this suture at a higher rate. Special precautions should be taken in elderly patients and patients with history of anemia and malnutrition conditions. As with any suture material, adequate knot security requires the accepted surgical technique of flat and square ties. The PDS suture knots must be properly placed to be secure.
The surgeon's knot is a surgical knot and is a simple modification to the reef knot.It adds an extra twist when tying the first throw, forming a double overhand knot.The additional turn provides more friction and can reduce loosening while the second half of the knot is tied. [1]
This antihelix plastic surgery is performed with the incision-suture technique. A long incision is made on the back of the ear and a strip of skin is removed. The cartilage is completely cut through in several places. With thick cartilage, the back of the antihelix is made thinner by using a scalpel to remove cartilage.
