smaller = more malignant
MC salivary gland tumor location
PAROTID GLAND
tx mucoepidermoid cancer
resect with MRND +/- postop XRT
preserve CN VII if parotidectomy
tx adenoid cystic cancer
(watch out: invades NERVES)
resect + MRND +/- postop XRT…. VERY SENSITIVE TO XRT
preauricular tumor
must rule out parotid tumor but don’t want to enucleate…
so diagnostic SUPERFICIAL PAROTIDECTOMY

mucoepidermoid
MC tumor overall of salivaries
pleomorphic adenoma
mgmt; superficial partoidectomy (total parotidectomy if malignant degeneration)

mgmt cholesteatoma
resect possibly also mastoidectomy
chemodectomya
vascular tumor of mdidel ear
resect
bleeding from posterior nose
internal maxillary aa or ehtmoid artery - consider angioembolization if hx HTN older patient
peritonsillar abscess mgmt
no airway issues…
needle aspirate and if still bad, drain into mouth (tonsillar bed)
retropharyngeal abscess patient
<10 yearsor Pott’s disease older
retropharyngeal abscess mgmt
AIRWAY (may need intubation) , drain through posterior pharyngeal wall
parapharyneal abscess
mediastinal spread via prevertebral and retropharyngeal spaces
drain through lateral neck to avoid carotid and IJ
ludwig angina
floor of mouth infection involving mylohyoid
neck mass
FNA > panednoscopy > CT scan> excisioanl bx +/- ipsi MRND and tonsillectomy followed by radiation
warthin tumor
benign partoid tumor (smokers, old people) b/l usually
FNA: cyst fluid
mgmt: watchful waiting vs superifial parotidectomy/WLE (not full thing
intraop facial nerve monitoring
helps with decreased transient nerve paralysis; but no change in permanent paralysis
anterior triangle boundaries
SCM, mandible, midline; has carotid sheath
posterior triangle boundaries
SCM, trap, 2nd third of clavicle; has CN XI
RLN function
motor of LARYNX except cricothyroid (SLN)
RLN course
R: ant to SCA loops behind and travels in TE groove
L: ant to aortic arch between Left common carotid and SCA and loops behind arch up in TE groove
H&N melanoma dx
FULL THICKNESS (no shave) bx
mgmt melanoma H&N
resect with same margins as other sites 1 - <1mm, 2 - >2 mm
how do melanomas drain in face
tragus line -
anterior: superfiical partoidectomy (drains to parotid) + selective ant neck dissection
posterior: selective posterior neck dissection without parotidectomy
vocal cord disruption after emergent intubation?
thyroid cartilage fracture
optimal trach placement? to avoid TIF
between 2nd and 3rd cartilage
when to operate on facial N?
within 72 hours… if lateral to lateral canthus
otherwise nonop if medial
vagus N
runs between IJ and carotid artery
how does long thoracic N run?
posterior to the middle scalene muscle

commando procedure
verrucous ulcer
well differentiated SCC…. in cheek from tobacco
rarely mets but
tx: resect full cheek +/- flap (no need for LN dissection)
tonsillar ca course

how does the facial nerve run
main trunk is 8mm deep to tympanomastoid suture line at the level of the digastric mm
