Vertical Mattress Suture

Vertical Mattress Suture Used if skin eversion is required and not possible with simple sutures Leaves obvious cross hatching Remove early

Horizontal Mattress Suture Good eversion Useful in thick glaborous skin (feet and hand) More ischaemia of wound edges

Subcuticular Suture Interrupted or running Superficial Dermis Place all sutures at same level No Suture marks Absorbable or non absorbable

Half buried Horizontal Mattress Suture Less Strangulation of flap edges Leave Knots on one side of wound only (eg. On areola for nipple suturing)

Other Closure Techniques Over and Over suture Quick Haemostatic Useful on scalp Beware ischaemia

Other Closure Techniques Skin staples Quick Temporary use to approximate skin Use forceps to evert edges and prevent inversion Remove early to prevent skin marks

Other Closure Techniques Skin tapes Approximate wound edges Use dermal sutures to take tension & prevent wound inversion
