1

Signs and symptoms

Asymmetry, crepitus, dental malocclusion, displacement of nasal septum, ecchymosis, lacerations and bleeding, limited movement of jaw, limited ocular movement, numbness, pain, swelling, visual disturbances

2

Mandibular Fractures

usually through blow to chin
Misaligned bite
Unable to open mouth

3

Mid-Face Fractures

when the face is struck with force from the front the bones collapse

4

Le Fort 1

fracture runs across lower face including hard palate and alveolus

5

Le Fort 2

pyramidal, extending variably upwards in the midline to involve the ethmoids

6

Le Fort 3

more transverse but uniformly higher than le fort 1
separates the face from skull

7

Management of middle face fracture

Mobilise front of face
Marked swelling and bruising
Marked bleeding
Often CSF leak
Normally assoc with spinal injuries
Requires constant suctioning of airways
NPA contraindicated

8

Zygoma (Malar) Fractures

strong bone transmits force to: orbit, zygomaticofrontal suture, may present with subcutaneous emphysema due to fracture of air sinus

9

Nose Fractures signs and symptoms

epistaxis, swelling, deformity, often accompanied by ecchymosis

10

Dental Trauma

assoc with facial and mandibular trauma
Get pt to run tongue around teeth
Broken or jagged teeth may cause excessive bleeding

11

Ear Trauma treatment

direct pressue to control bleeding
cold compress to reduce swelling
irrigate
avulsed pinna can be kept in moistened gauze

12

Orbit Fractures and Blunt Trauma signs and symptoms

contusion injury - black eye
traumatic hyphaema - bleeding
globe or scleral rupture

13

Penetrating Eye injuries signs and symptoms

dispacement of pupil
prolapse of intraocular content
evidence of intraocular foreign body or infection
reduced visual activity
hyphaema

14

Chemical burns to eye

alkali: reacts with proteins in the eyes to produce destruction of cells and softening of tissue, penetrates eye
acids: immediate and severe pain, destruction of surface tissue

15

Burns to eyes

arc eye from welders or skiers:
may affect both eyes, painful, weeping, red, sensation of foreign body, dye reveals tiny corneal abrasions

16

Retinal Haemorrhage caused by:

hypertension, occluded retinal vein, diabetes, shaken baby syndrome

17

Assessment and treatment of eye injuries

examine with pen torch, look for asymmetry and irregularity, assess eye movement, anterior chamber may contain blood

18

Scalp Lacerations

Skin
Connective tissue
Aponeurosis - loose muscular layer
Loose connective tissue
Pericranium

19

Nerve Damage

Facial nerve - motor supply to face and scalp,
Trigeminal nerve - cutaneous supply of face and scalp
