ENT Swellings Flashcards
State the borders of the anterior and posterior borders of the neck.
What is the carotid bulb/sinus?
Dilation of the common carotid just before it splits into internal carotid and external carotid. Contains baroreceptors to monitor BP.
State each lymph level (I to VI)
I = submental and submandibular II= upper interal jugular III = middle interal jugular IV = lower internal jugular V = posterior triangle VI = anterior
What lymph level does an oral cavity infection go to?
1
What lymph level does a submandibular gland drain?
What lymph level do the tonsils drain to?
II
What is the difference in location of congenital and metastatic masses?
Congenital masses: consistent in location
Metastatic masses: key to primary lesion
What are the clinical signs of quinsy?
Bulging around tonsils (peritonsilar area)
Deviated uvula
Trismus
Pain
How and why do deep space abscesses (quinsy) need to be drained?
Abscess can spread do other neck spaces and cause blockage to airway.
Tx by draining abscess and giving IV antibiotics
Parapharyngeal spce
Skull base to hyoid
Retropharyngeal space
Skull base to T1/T2
Danger space
Skull base to diaphragm. Area between retropharyngeal and prevertebral spaces.
Prevertebral space
Skull base to diaphragm
Lugwig’s angina
Caused from tooth infections
Strep, staph, fusobacterium and actinomycetes
Causes swelling or superior posterior of tongue therefore blockage to airway
Pain, trismus, drooling, fever, neck swelling, tongue protruded
Do BT for inflam markers and OPT
Tx by securing airway, drain abscess, remove infected teeth, IV antibiotics, IV steroids and rehudrate.
What is difference between acute viral and acute bacterial parotitis?
Paramyxovirus vs S.aureus
Bacterial causes abscess but viral does not
Bacterial can cause death
Tx for viral is more monitoring w analgesia and rehydration whereas bacterial also need to drain abscess and give antibiotics
Both show pain, pyrexia, dehydration and swelling
