1. NECK TRAUMA
DR SATINDER PAL SINGH

2. Background
 Few emergencies pose as great a challenge
as neck trauma. Because a multitude of organ
systems (eg, airway, vascular, neurological,
gastrointestinal) are compressed into a
compact conduit, a single penetrating wound
is capable of considerable harm.
 Airway occlusion and exsanguinating
hemorrhage pose the most immediate risks to
life. From the time when Ambroise Pare
successfully treated a neck injury in 1552,
debate has continued about the best
approach for particular neck wounds

3.  Neck trauma accounts for 5-10% of all serious
traumatic injuries. Approximately 3500 people die
every year from neck trauma secondary to hanging,
suicide, and accidents.
 Initially missed cervical injuries secondary to neck
trauma result in a mortality rate of greater than 15%.
 10% of neck wounds lead to respiratory compromise.
Loss of the airway patency may occur precipitously,
resulting in mortality rates as high as 33%.
 Zone I injuries are associated with the highest
morbidity and mortality rates.
 Sex-Trauma is more common among males than
among females.
 Age-Most people who experience neck trauma are
adolescents and young adults.

4. PATHOPHYSIOLOGY
A clear understanding of the
anatomic relationships within
the neck and the mechanisms
of injury is critical to devising a
rational diagnostic and
therapeutic strategy.

5. ANATOMY
 Think: vessels, airway, esophagus, spine, spinal cord, nerves,
ducts
 Superficial fascia: covers the platysma just below the skin
 Platysma: b/w the superficial and the deep fascia; violation
increases risk of damage
 Deep Fascia
 Investing layer: surrounds neck and splits to encase the SCM
and trapeziuz
 Pretracheal layer: adheres to cricoid and thyroid cartilage and
travels behind the sternum to attach to the pericardium:
PRETRACHEAL LAYER IS THE REASON THE NECK
CONNECTS TO THE MEDIASTINUM
 Prevertebral: envelops the cervical and prevertebral muscles
and extends to form the axillary sheath Carotid sheath
 Formed by components of all three layers

6. STRUCTURES AT RISK
 With the neck protected by the spine
posteriorly, the head superiorly, and the
chest inferiorly, the anterior and lateral
regions are most exposed to injury.
 The larynx and trachea are situated
anteriorly and are therefore readily exposed
to harm.
 The spinal cord lies posteriorly, cushioned
by the vertebral bodies, muscles, and
ligaments.
 The esophagus and the major blood

8. •Musculoskeletal structures at risk include
the vertebral bodies; cervical muscles,
tendons, and ligaments; clavicles; first and
second ribs; and hyoid bone.
•Neural structures at risk include the spinal
cord, phrenic nerve, brachial plexus,
recurrent laryngeal nerve, cranial nerves
(specifically IX-XII), and stellate ganglion.
•Vascular structures at risk include the
carotid (common, internal, external) and
vertebral arteries and the vertebral,
brachiocephalic, and jugular (internal and

9. •Visceral structures at risk include the
thoracic duct, esophagus and pharynx,
and larynx and trachea.
•Glandular structures at risk include
the thyroid, parathyroid, submandibular,
and parotid glands.
•Associated structures at risk of
intrathoracic injuries include the
esophagus, tracheobronchial tree, lung,
heart, and great vessels.

10. Zone Classification
Anatomy classification is excellent for
describing the static location of
structures
Injury is not static, and an injury to the
neck may enter the anterior triangle
and then pass through the posterior
triangle.
A more useful classification of neck
anatomy for trauma is the Zone
classification developed by Roon and

11. This classification system can guide
the clinician in the diagnostic and
therapeutic management
Based on level of injury to the neck in
a caudal to cranial orientation
Zone 1:
Lower Border = Clavicles
Upper Border = Cricoid Cartilage

12. ANATOMIC ZONES

13. Zones of the Neck
.
Zone I: Thoracic inlet to
Cricoid cartilage
Zone II: Cricoid
cartilage to the Angle

14. CLASSIFICATION

16.  Zone I the base of the neck, is
demarcated by the thoracic inlet
inferiorly and the cricoid cartilage
superiorly.
 Zone II encompasses the midportion
of the neck and the region from the
cricoid cartilage to the angle of the
mandible.
 Zone III characterizes the superior
aspect of the neck and is bounded by
the angle of the mandible and the

17. Zone I

 Spinal accessory nerve (cranial nerve XI):
Inability to shrug a shoulder and to laterally
rotate the chin to the opposite shoulder
 Hypoglossal nerve (cranial nerve XII): Deviation
of the tongue with protrusion

34. DIAGNOSTIC STRATEGIES
 TRIPLE SCOPE + Angiography
 Bronchoscopy
 Esophagoscopy
 Laryngoscopy
 Other: doppler, CTA, MRA

35. Diagnosis
 Imaging studies
 In addition to cervical and chest radiography, the
following supplementary tests may be useful:
 Computed tomography (CT) scanning
 Magnetic resonance imaging (MRI)
 Color flow Doppler ultrasonography
 Contrast studies of the esophagus
 Interventional angiography
 Endoscopy--Laryngoscopy, bronchoscopy,
pharyngoscopy, and esophagoscopy may be useful in
the assessment of the aerodigestive tract. Rigid
endoscopes are superior to flexible scopes.

36. General Indications for Angiography
(assuming patient not unstable)
•Hematoma
• Vascular bruit/thrill
• Decreased pulse in upper extremity
• Signs of CVA
General Indications for TRIPLE SCOPE
• Hematemesis
• Hemoptysis
• Chest tube air leak
• Subcutanoues or mediastinal air
• Oropharyngeal blood

37. Rosen’s signs of injury
SOFT signs HARD signs
 Hemoptysis/hematemesi
s
 Oropharyngeal bleeding
 Dyspnea
 Dyphonia/dysphagia
 SubQ or mediastinal air
 Chest tube air leak
 Nonexpanding
hematoma
 Expanding hematoma
 Severe active bleeding
 Shock unresponsive to
fluids
 Decreased/absent radial
pulses
 Vascular bruits/thrills
 Cerebral ischemia
 Airway obstruction

38. Goals of the Guideline
 Management of penetrating injuries to zone II of the
neck that penetrate the platysma.
1. Is mandatory operative management or selective
operative
management appropriate?
2. Can duplex ultrasonography (US) or CT angiography
rule
out an arterial injury in patients with no hard signs of
vascular injury on physical examination, thereby making
arteriography unnecessary?
3. Are both contrast studies (barium or gastrograffin
swallow)
and esophagoscopy needed to safely rule out esophageal

39. Mandatory versus Elective
Exploration
 Immediately life threatening: massive
bleeding, expanding hematoma,
hemodynamic instability,
hemomediastinum, hemothorax, and
hypovolemic shock.Immediate surgical
exploration
 Hemodynamically stable ,non–life-
threatening features can undergo thorough
imaging investigations to determine the
extent of injury.

40. Initial Management
Initial Management is the same as all trauma
cases
 A : airway with C-spine control
 B : breathing and ventilation
 C : circulation
 D : disability and neurologic status
 E : exposure and evaluation other injury

41. Airway
◦ Securing the airway should be
considered if the patient is going to be
leaving your supervised area
◦ Endotracheal intubation using rapid
sequence technique is the first choice
◦ Cricothyrodotomy is second line
treatment when intubation is not
successful
◦ Care should be taken to when intubating
to avoid an injured trachea

42. • Patients with acute respiratory distress need a
definitive and secure airway
• In neck trauma there is sometimes a debate as to
when to intervene
 Multiple blind intubation attempts will
risk enlarging a lacerated piriform sinus
wound and extending it iatrogenically
into the mediastinum.
• Blood and air from facial and neck injuries can
distort the normal anatomic appearance and
increase the difficulty of intubation
• Tracheal tear may be exacerbated by extending the
neck.

43. Breathing
◦ All patients should receive high-flow oxygen
◦ Based on the zone and the proximity to the
thoracic inlet, there could be simultaneous
injury to the thorax
◦ If you notice any difficulty ventilating then
suspect either upper airway injury or thorax
◦ Evaluate for asymmetric breath sounds
◦ Consider tension pneumothorax if there is
evidence of tracheal deviation

44. Circulation
◦ Active bleeding should be addressed
immediately by direct point pressure
◦ Do not clamp bleeding vessels
because you could cause further
ischemia
◦ Avoid placing IV access where the
flow would head towards the injured
area.
 Extravasation could create more
distortion and compression

45. Disability
◦ Examine and inspect for evidence of
focal neurological deficit
◦ This could suggest direct nerve
injury, or spinal cord injury or
vascular injury leading to ischemia

46. Zone 1 injury
 Below cricoid, dangerous
area
 Protect zone  bony thorax
and clavicle
 Motality rate 12 %
◦ Potential for injury to great
vessel and mediastinum
 Mandatory exploration : not
recommend
 Angiography and esophageal
evaluation: usually suggest
◦ > 1/3 no symptom at
presentation

47. Zone 1 injury
 Esophageal evaluation
endoscopy , contrast
esophagogram
◦ Contrast medium
 Barium- based
 Gastrografin ( meglumine diatrizoate)
◦ Combination tests should not miss an
njury
 CT scan
◦ Determine the path of projectile

48. Zone 2 injury
 Largest zone,most common site of
trauma 60-75%
 Between angle of mandible & inf
border of cricoid cartilage
 Isolate venous injury &
pharyngoesophageal injury most
common structure missed clinically
 All pt. are admitted for observation
and 24 hr re-evaluation
 50% of death  hemorrhage from
vascular structure

◦ Stable pt. who has persistent hemorrhage
◦ Neurodeficit compatible with adjacent vascular structure
damage eg. Horner’s syndrome , hoarseness
 Need exploration
◦ Positive arteriography
◦ Negative arteriography but positive clinical sign
 Asymptomatic in zone 2
◦ Controversy,
 No sig difference btw. Clinical exam & angiography
◦ CTA fast ,minimal invasive in hemostatic stable

59. Technique of vascular repair
 End to end or autogenous graft
reccomended when stenosis is
evident by arteriography
 Ligation of common or internal
carotid a.reserved for
irreparable injury and in pt, who
are in a profound coma state
 Delayed complication from
unrepaired vascular injury
◦ Aneurysm formation
◦ Dissecting aneurysm
◦ AV fistulas

60. Pharynx and esophageal
injury

rigid endoscopy
◦ Exam entire cervial and upper
esophagus
◦ No perforation missed

63. Digestive tract evaluation
 Suspicious pharyngeal perforation

mediastinum
 Repeat endoscopy or neck exploration
◦ Esophageal injury in the early phase
 Two layer closure with wound irrigation

 Surgical approach
◦ Zone 1
 Median sternotomy
 Thoracotomy
◦ Zone 2
 Collar incision
 Apron incision
◦ Zone 3
 Consult neuroSx

67. Blunt neck trauma
 motor vehicle accidents and sports
 result in laryngeal, vascular, and
digestive injury
 easily underdiagnosed because their
onset can be delayed
 occult cervical spine injury
 Strangulation
 Blows from fists or feet
 Excessive manipulation

68. Blunt Neck Trauma
 Blunt trauma to the neck is less
frequent in occurrence
 Mechanism is often related to motor
vehicle collisions
◦ Hyperextension
◦ Rotation
◦ Hyper flexion
◦ Direct blows against a non mobile object
(most commonly seatbelts)

69. Laryngotracheal Injury
 Signs and symptoms:
◦ Difficulty swallowing
◦ Pain with swallowing
◦ Difficulty breathing (feeling breathless)
◦ Hoarseness of voice (or change in voice)
◦ Subcutaneous emphysema
◦ Tracheal deviation
 However signs and symptoms may be
absent even with a major injury

70.  Common to all traumatic mechanisms is the
direct transfer of severe forces to the larynx.
These forces have the potential to produce
many devastating injuries, including mucosal
tears, dislocations, and fractures.
 Edema, hematoma, cartilage necrosis, voice
alteration, cord paralysis, aspiration, and airway
loss may accompany these injuries.
 Common signs of laryngeal injury include
stridor, subcutaneous emphysema, hemoptysis,
hematoma, ecchymosis, laryngeal tenderness,
vocal cord immobility, loss of anatomical
landmarks, and bony crepitus.

71. Laryngotracheal Injury
 Blunt trauma to neck with swelling and
subcutaneous emphysema

involved in a motor vehicle

73. CT scan (A) revealing a paramedian fracture (see arrow) from an acute blunt laryngeal
trauma . This young man presented 1 week after being struck on the left side of the neck
with a hockey stick. Note that the 3D reconstruction (B) provides valuable information as
to the shape of the fracture and demonstrates that the anterior commissure has been
displaced

74. Laryngeal injuries vary by
anatomical location
 Supraglottis: Traumatic forces commonly
produce horizontal fractures of the
thyroid alae and disruption of the
hyoepiglottic ligament with subsequent
superior and posterior displacement of
the epiglottis.
 Repositioning of the epiglottis may result
in the creation of a false lumen anterior
to the epiglottis. This lumen may tunnel
into the larynx or pass anterior to the
thyroid cartilage and cause cervical

75.  Glottis: Traumatic force results in cruciate
fractures of the thyroid cartilage near the
attachment of the true vocal cords.
 Subglottis: Crushing forces to the cricoid
cartilage cause injury to the cricothyroid joint
and may result in bilateral vocal cord paralysis
from recurrent laryngeal nerve damage.
 Hyoid bone: Found more commonly in women,
hyoid fractures tend to occur in the central part
of the hyoid bone because of the inherent
strength of the cornua.

76. Cricoarytenoid joint: Traumatic forces that
displace the thyroid alae medially or cause
compression of the larynx against the cervical
vertebrae often result in cricoarytenoid
dislocation. This injury generally occurs
unilaterally.
Cricothyroid joint: Injury occurs when traumatic
forces to the anterior portion of the neck cause
the inferior cornu of the thyroid cartilage to be
displaced posterior to the cricoid cartilage. This
dislocation limits cricothyroid muscle function and
therefore pitch control. Injury to the recurrent
laryngeal nerve may also contribute to vocal cord
paralysis

78. Laryngotracheal Injury
 Management:
◦ High index of suspicion is required to
diagnose these types of injuries especially in
the absence of classic symptoms
◦ Securing an airway is the initial focus.
 Endotracheal intubation should be attempted by the
most experienced person
 Other authors suggest immediate tracheostomy to
avoid creating a false path or further injury to the
unstable airway
 Cricothyrodotomy should be avoided as this may
worsen the injury

 Aphonia
 Dysphonia
 Odynophagia
 Dysphagia
 Postoperative
complications (eg,

 Vocal cord injuries (eg,
paralysis, fixation)
 Fistula

esophageal, or
pharyngocutaneous)
 Cosmetic deformity
 Chronic aspiration

89.  Subglottic stenosis is a difficult
complication to treat effectively.
Incomplete ring and weblike subglottic
stenosis can be treated with laser
excision or incision and dilation.
 More significant stenosis may require
anterior or posterior cricoid splits with
cartilage grafting.

90. McCaffrey system of
laryngotracheal stenosis
classlficatlon.

91.  The most common problem in the immediate
postoperative period is the development of
granulation tissue and ulceration from exposed
cartilage.
 The main concern with granulation tissue
formation is the potential for the development of
fibrosis and eventually stenosis.
 Many techniques have been used to slow the
formation of granulation tissue, including
systemic and intralesional administration of
corticosteroids, long-term splinting, and low-
dose radiation.
 Debulking granulation tissue through
endoscopy is probably the most effective
alternative treatment currently available.

92. Laryngeal trauma complications can manifest as
inadequate voice and failure to decannulate. These can
be prevented or treated in the following ways
Granulation tissue
 Covering all exposed
cartilage to prevent
 Avoiding stents when
possible
 Careful excision
Laryngeal stenosis
 Excision with mucosal
coverage
 Stenting selected
cases
 Laryngotracheoplasty
 Tracheal resection
with reanastomosis
Vocal fold immobility
 Observation
 Vocal fold injection
 Thyroplasty-type vocal
fold medialization
 Arytenoidectomy and
vocal fold lateralization
for bilateral paralysis
