1

What are the properties of the skin?

tension, shear, and viscoelasticity

2

What is tension determined by?

the pull of collagen and elastin in dermal and hypodermal tissues

3

What is the shear skin property?

mobile areas of skin with forces on either wound edge opposing the other

4

How does viscoelasticity occur?

adaptation to prolonged stress

5

What are the tension relieving techniques?

undermining tissues, tension-relieving sutures, skin stretching, relaxing incisions

6

How do you undermine tissue?

You use metzenbaums to dissect superficial to the muscle

7

What does undermining take advantage of?

the skin's elastic potential

8

What type of dissection does undermining use?

blunt and sharp dissection

9

When should you not use undermining?

when the patient has cancer

10

What are some tension-relieving sutures?

interrupted vertical mattress, interrupted or continuous horizontal mattress, quilled/stented/bolster, far-near-near-far, far-far-near-near, cruciate, and walking sutures

11

What tissues is the vertical mattress used for?

skin, gingiva, fascia, and tissues under tension

12

What bites are used for the vertical mattress suture?

far-far, near-near

13

Which bites in the vertical mattress suture should be deep?

the far bites

14

How far from the incision should the near bites in the vertical mattress suture be?

2 mm

15

If the vertical mattress is tight, what type of suture pattern is it?

everting

16

When does the vertical mattress appose best?

when the near bites are close

17

Is the vertical mattress or horizontal mattress stronger?

vertical

18

In what type of tissue should you use the quilled/stented pattern?

skin under tension

19

What is the quilled/stented suture a modified suture of?

the interrupted vertical mattress that loops over a stent

20

What type of pattern is the quilled/stended suture coupled with?

an appositional pattern at the skin edge

21

What is a potential complication associated with the quilled/stented suture pattern?

ischemia between sutures or under stents

22

When should the quilled/stented suture pattern be removed?

earlier than the remaining sutures

23

In what type of tissue should you use a far-near-near-far pattern?

skin and fascia under tension

24

What is the far-near-near-far pattern a modification of?

a vertical mattress pattern

25

The far-near-near-far suture pattern avoids excess ______ at the wound edge.

tension

26

What is the thickness of the bites in the far-near-near-far suture?

full thickness

27

In what type of tissue should you use a far-far-near-near pattern?

skin and fascia under tension

28

What is the far-far-near-near pattern a modification of?

modified vertical mattress

29

The far-far-near-near suture avoids excess ____ at the wound edge?

tension

30

What is the thickness of the bites in the far-far-near-near pattern?

full thickness
