The vertical mattress stitch is most commonly used in anatomic locations which tend to invert, such as the posterior aspect of the neck, and sites of greater skin laxity such as the closure of lax skin after removing a dermoid cyst or reduced subcutaneous tissue (e.g., the shin) that do not provide adequate subcutaneous tissue for dermal closure. [6]
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.
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.
Blumenthal side cuts are short cuts at the ends of a straight incision which angle obliquely away from the cornea. This induces minimal astigmatism and is used for a wide tunnel. [1] A "smile" incision is parallel to the edge of the cornea. It is an easy incision but induces more astigmatism and is more prone to separation. [1]
Continuation of the 2 continuous sutures from each of their corners results in both sutures meeting at the middle anterior portion of the anastomosis. [6] The suture loops are then tightened and finished with at least 8 knots. [6] In both end-to-side and side-to-side CDD, the anastomosis should have a diameter of at least 14mm. [6]
The suture suspension techniques are described to lift, if necessary to form volume and to correct position of soft tissue without traditional incisions. The techniques consist of passing closed sutures , [ 3 ] by needle perforations only, to lift movable fascias and fix them to non movable skeletal structures [2] in several facial and body areas:

There are several methods that can be implemented to achieve primary closure of a wound, including suture, staples, skin adhesive, and surgical strips. Suture is the most frequently used for closure. [27] There are many types of suture, but broadly they can be categorized as absorbable vs non-absorbable and synthetic vs natural.
