Currently, we use dissolvable monofilament stitches with special hooks for most body surgeries (stomach, arms, thighs, breasts, buttocks). They are also known as barbed stitches. These sutures distribute the stretching of the skin more evenly and are less likely to cause infections.
Incisions after liposuction are stitched with dissolvable multifilament sutures which dissolve within 7-14 days.
Non-dissolvable stitches are usually used for eyelid surgery and rhinoplasty, as the skin is very thin in these areas and suture resorption can lead to a very strong reaction. Such sutures need to be removed after 7-10 days.
