BASIC SURGICAL SKILLS 2023

What is the type of suturing method shown in the diagram?

• Figure of 8

• Simple interrupted

• Horizontal mattress

• Vertical mattress

What is the length of the suture needle based on the packaging label?

• 30cm

• 19mm

• 45mm

• 18mm

Which statement is false?

• The knot should be positioned so that it does not fall directly over the incision line because this causes additional pressure on the incision

• When passing the needle through tissue, the needle should enter the surface of the mucosa at a right angle to the surface

• If a three-cornered flap is used, the vertical end of the incision must be closed separately

• Mucoperiosteal flap should be tied tightly

Which statement is false?

• Soft tissue wounds associated with dentoalveolar trauma are always treated before the management of the hard tissue injury

• If a contusion does not stop expanding, a hemorrhaging artery within the wound is likely

• A contusion generally requires no surgical treatment

• After adequate anesthesia is provided, the surgical management of lacerations involves four major steps: (1) cleansing, (2) debridement, (3) hemostasis, and (4) closure

This fracture characteristically

• Present with bilateral circumorbital ecchymoses and facial edema

• Cause cerebrospinal rhinorrhoea

• Cause infraorbital anaesthesia

• Cause bleeding into the antrum

Below are cleansing agents for laceration wounds except

• Chlorhexidine

• Carnoy’s solution

• Iodine

• Normal saline

Longer periods of IMF can lead to bony ankylosis or fibrosis and severe limited mouth opening

• True

• False

Which statement is false?

• If adequate bony reduction has occurred, IMF may provide adequate stabilization during the initial bony healing phase of approximately 6 weeks.

• Indications for open reduction include unfavorable fractures, as in an angle fracture

• In the case of a fracture of an edentulous patient, the mandibular dentures can be wired to the mandible with circumzygomatic wiring

• The maxillary denture can be secured to the maxilla using bone screws to hold the denture in place

Which of the following is false?

• 
• 
• 
• 

Which of the following suture materials is absorbable?

• PDS
