Suturing – tension relieving suture patterns

Both vertical and horizontal mattress patterns are everting – they force the cut edges outward. NFFN patterns are appositional and bring tissue layers into direct contact with the same layer on the opposite side.

With a mattress suture, you can also place a simple continuous pattern. With this approach, you can remove the larger suture used for the mattress pattern after the skin stretches (3-4 days), leaving the more cosmetic simple continuous suture to finish the job.
