Suturing Techniques Quiz

Which material is not a type of absorbable suture?

• Dacron polyester

• Nylon

• Silk

• Gut

What is the characteristic of a reverse cutting needle?

• It has a flat internal surface

• It is made of organic material

• It is the most popular type of needle

• It is reusable

What is the largest size of suture material?

• No. 3

• No. 5 - 0

• No. 3 - 0

• No. 7 - 0

Which suture material is obtained from deep flexor tendons of cattle?

• Gut

• Collagen

• Nylon

• Polyglycolic acid

What is the principle of suturing that involves passing the needle from the thinner to the thicker side of the tissue?

• The needle should enter the tissue perpendicular to the surface

• The needle should be passed through the tissue following the curve of the needle

• The distance that the needle is passed into the tissue should be greater than the distance from the tissue edge

• The suture should be tied so the tissue is merely approximated, not blanched

Which type of suture method provides rapid closure and even distribution of tension over the entire suture line?

• Continuous structure

• Locking continuous structure

• Interrupted structure

• Mattress structure

What is the advantage of a locking continuous suture?

• The suture is aligned itself perpendicularly to the incision

• It provides more tissue eversion than any other method

• It prevents continuous tightening of the suture as wound closure progresses

• It runs parallel to the blood supply to the edge of the flap

Which suture method is used for intraoral grafting or eversion closure and provides a very smooth and continuous closure?

• Sub cuticular suture

• Figure of 8 suture

• Continuous structure

• Interrupted structure

What is the disadvantage of a figure of 8 suture?

• It provides broad contact with the wound

• It constricts the blood vessels leading to necrosis and dehiscence

• It does not interfere with wound healing

• It limits the blood supply to the flap edge

Which type of needle is most commonly used for skin closure in places with adequate access?

• Eyed needle

• Swaged needle

• Curved needle

• Straight needle
