Soft Tissue Injuries

Question 1

What’s abrasion ?

Answer 1

caused by the force of an object rubbing on the surface of the skin


Question 2

What’s Contusions ?

Answer 2

are bruises caused by rupture of blood vessels subcutaneously or deeper within tissue

Question 3

What’s Lacerations ?


Answer 3

are splits in the skin and underlying tissues caused by blunt impact that crushes the tissues over a site of bony prominence

Question 4

What’s Incised wounds ?

Answer 4

These wounds are ‘clean’ incisions through the skin and deeper tissues that are caused by a sharp instrument or object such as a knife or broken glass



Question 5

What’s avulsion ?

Answer 5

In an avulsion injury, tissue at the wound site may be displaced from the underlying tissue layers yet still be partially attached



Question 6

What’s bite wound ?

Answer 6

wounds caused by rapturing skin and underlying tissue with teeth of an animal or human



Question 7

What’s High-velocity missile injuries ?

Answer 7

Injuries caused by a high-velocity object, such as a bullet or shrapnel (which may include biological – human – body parts)


Question 8

What’s hematoma ?

Answer 8

A haematoma is a collection of blood within the soft tissues



Question 9

What’s the key questions must be answered ?

Answer 9

How and where did it happen?
When did it happen?
What is relevant in the medical history? 
Tetanus status?




Question 10

What’s the contraindications in wound exploration and where we should inspect ?

Answer 10


 ■ Do not explore a gaping penetrating wound of the neck (deep to the platysma) outside the operating theatre environment

■ Blood vessels – Identify bleeding vessels and those in spasm 


Question 11

Why you should Always check for other anatomical structures damage and foreign body in the wound area ?

Answer 11

Cause avulsion and skin flap can hide fractured skull and foreign bodies like tooth fragments and schrapnels of metal.


Question 12

In why cleansing serve ?

Answer 12

the most important stage in reducing the risk of infection and in preventing possible ‘tattooing’ of the tissues by debris 


Question 13

What are cleansing solutions available ?

Answer 13


■ Normal saline. 
■ Chlorhexidine 0.5% (aqueous). 
■ Chlorhexidine 0.5% (alcohol based). 
■ Iodine (povidone iodine) 1% (aqueous). 
■ Iodine (povidone iodine) 1% (alcohol based).


Question 14

What’s Wound closure materials of ?


Answer 14

■ Adhesive paper strips (Steri-Strips, Suture Strips). 
■ Tissue glue (Dermabond, Tisseel, and Histoacryl). 
■ Sutures – Resorbable. 
■ Sutures – Nonresorbable. 
■ Staples – These are rarely if ever used on the face.



Question 15

What’s breakage and cutting out ?

Answer 15

■ Breakage – the tensile strength of the suture material is too low or the suture is too small.

■ Cutting out – too fine a suture material is used or the suture is placed in friable tissue. 


Question 16

What’s knot slippage and extruded suture ?

Answer 16

Knot slippage – knot tying is inadequate. Every material other than silk benefits from an extra throw on the conventional surgeon’s knot.

■ Extruded suture – this occurs in combination with infection

Answer 17

Resorption that is too rapid – nonabsorbable or more slowly absorbable suture should have been used. 
■ Removal too early – suture is removed before sufficient healing.

Question 18

What’s Undermining of the skin ?

Answer 18


When tissue loss is not extensive and mainly involves skin, a small border of skin on either side of the wound may be carefully separated from the underlying fat.

This allows advancement of the released elastic skin across the wound



Question 19

What’s drains ?

Answer 19


Deep or extensive wounds may require the insertion of a drain, which lies along the length of the depth of the wound. The purpose of a drain is to remove excessive inflammatory exudate and ‘oozed’ blood from the wound to prevent it from collecting as a focus of infection




Question 20

When we do skin grafting ?

Answer 20

when large areas of skin have been lost. 


Question 21

What’s the difference between local and distant flap ?

Answer 21

The donor area

Question 22

Which Factors affecting wound healing ?

Answer 22


1. Site of the wound (e.g. tissue, blood perfusion, movement). 
2. Timing of treatment. 
3. Nature of treatment (correct or incorrect technique). 
4. Infection. 
5. Systemic factors (e.g. age, health, nutrition, steroids).

Question 23

What’s preoperative wound infection etiology ?

Answer 23

Preoperatively 
■ Wound contamination with organisms at the time of trauma. 
■ Delay in treatment. 


Question 24

Postoperative wound infection etiology ?

Answer 24

Postoperatively 
■ Contamination at the time of injury. 
■ Poor cleansing/wound débridement or poor aseptic operative technique. 
■ Poor closure of the wound. 
■ Failure to administer appropriate prophylactic antibiotics. 
■ Host susceptibility.

Question 25

How to mimize scarring ?

Answer 25

Good wound care, early suture removal, moisturization and massage all help to reduce scarring.

Nonsurgical techniques to improve scars include silicone-based gels for self-application,
silicon pressure dressings, intralesional steroids and steroid-impregnated tape.

Question 26

Scarring operation in how much time done ?

Answer 26

18 months after wound closure
