Resp 2 Flashcards
what are guttural pouches
mucosal lined air-filled outpouchings of auditory tubes
does pharynx have supportive structures
no, no cartilagenous rings
each guttural pouch connects to the
nasopharynx
are the GPs open or closed during swallowing
open (equalize pressure)
each GP is divided into ___ and ___ compartment. which has more neurovascular structures?
lateral and medial
medial
nerves associated with which action are in the medial GP compartment
swallowing
the common carotid artery diverges into which vessels as going up neck
internal carotid (goes to GP)
external carotid
occipital artery
signs of guttural pouch disease
Epistaxis
Nasal discharge
Dysphagia
Dyspnea
Diseases associated w guttural pouches
mycosis
empyema
tympany
OI, OM
cyst, FB
describe guttural pouch mycosis
fungal plaques form over vessels
why does GPM show epistaxis from both nostrils
caudal to nasal sepctum
c.f. sinus disease will just show on one nostril
why take care doing endoscopy for GPM
not to disrupt clot –> fatal bleed
GPM tx
surgical occlusion of the artery
why don’t occlude just one side?
will cause backlog on other side of circle of willis, must occlude both sides
what is guttural pouch empyaema
purulent material (chondroid) in pouch
what do you want to test for iwth empyaema
strangles
tx for guttural pouch empyaema
flushing +
endoscopic removal
what is guttural pouch tympany? who gets it?
gas distension
foals (failure of pressure normalization)
signs of GP tympany in foals
milk at nostril (also in cleft palate)
gaseous swelling behind mandible
tx for GP tumpany
foley catheter OR surgical fenestration
*allows for pressure equilization
temporohyoid osteoarthropathy
progressive dx of middle ear, painful
temporohyoid osteoarthropathy - signs
head shaking, ear rubbing, not wanting to be ridden
rupture of strap muscles - caused by?
falling over backwards
strap muscle fxn
flexure of neck
