  1. Advanced Suturing Techniques Bucky Boaz, ARNP-C

  2. Subcutaneous Stitch • Deeper wounds or wounds under tension. • Inverted knot. • Begin at bottom of wound edge and come up. • Go straight across incision and down.

  3. Running Stitch • Indicated for low risk repairs. • Tie knot at one end, do not cut until repair complete. • Faster technique. • Plastic surgery quality.

  4. Running Locked Stitch • Modified running stitch. • Used to prevent slippage of loops as running stitch continues. • Allows for continuing stitch along irregular laceration.

  5. Vertical Mattress Stitch • Promotes eversion of the skin. • Tension or very thick skin. • Enter wound on one side, pierce other side twice, and exit on side entered.

  6. Horizontal Mattress Stitch • Needle is introduced in normal fashion. • Second bite is placed ½ cm adjacent to exit site. • Brought back next to original insertion. • Tie knot.

  7. Intracuticular running suture • Used to close linear wounds that are not under much tension. • Yields an excellent cosmetic result. • The ends of the suture do not need to be tied. • Taping under slight tension will preserve approximation.

  8. Three-point or half-buried mattress suture • Closure of the acute corner of a laceration without impairing blood flow to the tip.

  9. Three-point or half-buried mattress suture • Needle is inserted into nonflap portion of the wound at the mid-dermis level; and then at the same level, the suture is passed transversely through the tip and returned on the opposite side of the wound paralleling the point of entrance.

  10. Three-point or half-buried mattress suture • The suture is tied, drawing the tip snugly into place in good opposition. This same approach can be utilized in closing a stellate 4- or 5-point laceration, drawing the tips together in a purse-string fashion.

  11. Parallel Lacerations • The horizontal technique is used to cross all lacerations • Wound tapes can be used if low tension • If island in middle is wide enough, interrupted sutures can be used

  12. Special Anatomic Sites

  13. Extramarginal Lid Lacerations • Upper lid lacerations are usually closed with simple interrupted • Intramarginal lid lacerations are best left to plastics

  14. Eyebrow lacerations • Most eyebrow lacerations can be closed without tissue debridement • If devitalized, excise tissue parallel to hair shaft

  15. Ear • 72-hr window to drain perichondral hematoma • Simple noncartilaginous lacerations are closed with interrupted or running sutures • Lacerations involving cartilage

  16. Lip • Must approximate vermilion border • Through and through lacerations involve orbicularis oris muscle • Repair muscle first • Then, vermillion border • Then, rest
