head and neck surgery Flashcards
pinna laceration tx
clip/clean, debride, explore, flush
tell O about cosmetic defects
what layer to suture to for ear repair
perichondrium
blood supply to pinna
runs vertically, need to suture vertically
aural hematoma
self trauma-> separation of skin from cartilage-> blood accumulates-> fibrosis/contraction (permanent deformation)
tx- serpentine incision for drainage, meshing incisions
nasopharyngeal polyps
pedunculated non-neoplastic mass in ear canal/nasopharynx
young cats-> otitis externa, stertor, sneezing, head shaking
dx- scope, imaging, histopath
tx- traction/avulsion (most common)
endoscopic curettage
CO2 laser
ventral bullae osteotomy (33%- best option)e
end stage otitis externa
recurrent ear infections, head shaking, scratching
dx w PE, aural exam, neuro exam LN, check skin for allergies, neoplasia
end stage ear surgeries
lateral canal ear resection- cut down vertical canal and expose horizontal canal opening
vertical canal ablation- remove vertical canal and create opening at base of ear
TECA-BO- remove ear canal and open lateral bulla/tympanic cavity
sialocele
cranioventral neck swelling, non painful.
dx w FNA, ddx: abscess, neoplasia, sialolith
palate vs lip defect
cleft lip is cosmetic only, plate= risk of aspiration
cleft palate tx
nursing care, tube feeding
congenital- 3-4m sx
acquired- wait for injury to declare itself
close w well vascularized tissue, no tension. use flaps
feline hyperthyroid
benign tumour, polyphagia weight loss, PU/PD
sx, IL131
canine thyroid tumour
malignant cervical mass, highly vascular40% have mets at diagnosis
need advanced imaging
more mobile= better prognosis
canine hyperparathyroid
hematuria, stranguria
hyper ca, ca stones
HIGH iCA AND NORMAL PTH
sx removal of parathyroid, excellent prognosis
