The set-back dermal suture
The set-back dermal suture
This approach is frequently used in areas under significant tension, and as an alternative to the buried vertical mattress as a standard buried technique.3 Since it is easier to place than a buried vertical mattress suture, this technique may be used by budding surgeons, medical students, and residents as the workhorse technique for deep tension-relieving sutures (Figs. 13-4 through 13-6).
Figure 13-4. The needle is inserted through the underside of the dermis, exiting again through the underside of the dermis set back from the wound edge.
Figure 13-5. This is repeated on the contralateral wound edge.
