Suture may define as
Any strand of material used to ligate
blood vessels or to approximate
tissue

1. Absorbable: Suture that is completely
broken down
by the body (dissolving suture)
2. Non-absorbable: Suture is not broken
down (permanent suture)

The simple interrupted suture is the gold
standard and the most commonly employed
suture.
same depth on each side of the incision or
wound, otherwise the edges will overlap.
Sutures are usually placed approximately 5
to 7 mm apart and 1 to 2 mm fromthe skin
edge,

Vertical mattress sutures may be used
when eversion of the skin edges is
desired and cannot be accomplished
with simple sutures alone.
Vertical mattress sutures tend to leave
the most obvious and unsightly cross-
hatching if not removed early

Horizontal mattress sutures also
provide approximation of the skin
edges with eversion.
They are particularly
advantageous in thick glabrous
skin (feet and hand).

known as running simple sutures
can be placed rapidly but depend
on the wound edges being more-
or-less approximated beforehand.
A continuous suture is not nearly
as precise as interrupted sutures

Skin staples are particularly useful as a
time saver for long incisions or to
position a skin closure or flap
temporarily before suturing.
Staples must be removed early to
prevent skin marks and are ideal for the
hair-bearing scalp

Skin tapes can effectively approximate
the wound edges, although buried
sutures are often required in addition
to skin tape to approximate deeper
layers.
Skin tapes can also be used after skin
sutures are removed to provide added
strength to the closure

Skin adhesives have been developed,
and may have a role in wound closure,
especially in areas where there is no
tension on the closure, or where
strength of closure has been provided
by a layer of buried dermal sutures.
Adhesives, by themselves, however, do
not evert the wound edges.
