Random Neck Flashcards
what are some causes of cervical pain?
- inflamed lymph nodes
- muscle strain
- protruding IV discs
what causes most chronic cervical pain?
- bony abnormalities - cervical osteoarthritis
- trauma
what can fractures and dislocations of the cervical vertebra cause?
injure spinal cord and/or vertebral arteries and sympathetic plexuses passing through transverse foramina
what fractures occur in people who are manually strangled by compression of the throat?
fracture of the hyoid or of the styloid process of the temporal bone
what can fracture of the hyoid result in?
difficulty swallowing and maintaining separation of alimentary and respiratory tracts -> can cause aspiration pneumonia
what does paralysis of the platysma cause?
causes skin to fall away from neck in slack folds
what happens if surgeons don’t carefully suture the skin and edges of platysma?
skin wound will be distracted (pulled in diff directions) by the contracting platysma
what contains the spread of abscesses/infections in the neck?
investing layer of deep cervical fascia
if you have infection in each of these places, where will it spread:
- b/w investing and muscular part of pretracheal
- b/w investing and visceral part of pretracheal
- posterior to prevertebral layer
- just to superior edge of manubrium
- into thoracic cavity anterior to pericardium
- laterally - swelling posterior to SCM or go through the prevertebral fascia into retropharyngeal space
what can a retropharyngeal abscess cause?
dysphagia and dysarthria (difficulty speaking)
what is pneumomediastinum?
air from a ruptured trachea, bronchus, or esophagus - can pass superiorly into neck
cervicothoracic ganglion block
- blocks transmission of stimuli through the cervical and superior thoracic ganglia
- relieves vascular spasms involving brain and upper limb
what does a lesion of a cervical sympathetic trunk cause?
horner’s syndrome
describe horner’s syndrome
- miosis (constriction of pupil from paralysis of dilator pupillae)
- ptosis (drooping of superior eyelid from paralysis of tarsal mm)
- enophthalmos (sinking in of eye from paralysis of smooth mm in floor of orbit)
- anhydrosis (vasodilation and absence of sweating on face/neck from lack of sym nerve supply to vessels/glands)
what is removed in radical neck dissections?
- deep cervical lymph nodes and tissues around them
- most cutaneous branches of cervical plexus
