CLINIC EXAM PART 2 Flashcards
breeds predisposed to “Nauubo every exercise”
Thoroughbreds
- Racing horses
(Most used) imagine technique for awkward breathing during exercise
endoscopy
meaning of LLH
Left laryngeal hemiplegia
what are the aka of LLH
RLN (recurrent laryngeal
neuropathy), laryngeal paralysis, “roaring”
what nerve is affected in LLH if it is not from genetics
Left recurrent larnygeal nerve
which is more predisposed to LLH, left or right nerve
left, 95%
Presents as roaring
LLH
what grade? Full abduction of the arytenoid cartilages
during inspiration
1
Partial abduction of the affected arytenoid cartilage (b/w full and the resting position)
slightly affected abduction, slighlty curved
2
abduction Held at the resting position
3
Collapse into the contralateral half of the
rma glottidis during inspiration
4
tx for LLH
Laryngoplasty
Ventriculocordectomy
Sabay
Nerve implantation
easiest to do for tx for LLH; what are disadvantages
Laryngoplasty; Downside - prone to dumi, irritants, problematic particles
what grade gagawin ang laryngoplasty
3 or 4
this is a tieback method for LLH
Laryngoplasty
called “Hobday” operation”
Ventriculocordectomy
Removal or cut away of laryngeal
ventricle and vocal cord
Ventriculocordectomy
when can sabay 1 and 2 for LLH done
fully anesthetized
Laryngeal reinnervation of the CAD (cricoarytenoideus dorsalis) muscle (move one of the nerves from right to left)
Nerve implantation
what muscle is reinnervated for LLH
CAD (cricoarytenoideus dorsalis) muscle
EE
Epiglottic entrapment
presented as inflamed, broken down larynx
LLH
Loose aryepiglottic folds & mucosa
displace dorsally
EE: Epiglottic entrapment
“Wrapping” over the epiglottis, like a glove
Aryepiglottic fold wraps around the epiglottis
EE
breeds predisposed to EE
throughbreds/racehorses
top 2 meds used for EE
Flunixin Phenylbutazone
Surgical transection for EE
Laryngotomy
bistoury transection
best tx for ee
surgical transection
Remove the entire entrapping tissue for EE
Complete excision
DDSP
Dorsal displacement of the soft palate
Soft palate displaces dorsally; Airway obstruction!
DDSP
produces gurgling noise
DDSP
DDSP pero no sound, just signs
silent displacers; 10-20%
predisposed breeds for DDSP
racehorses
Bulging yung epiglottis under the soft palate
DDSP
tx for DDSP
Antinflamm
Surgical transection (best)
Larnygeal tie-forwards
bbest tx for DDSP
Surgical transection
- Staphylectomy
- laser/cautery assisted
Surgical repositioning of the larynx for DDSP
Larnygeal tie-forwards
- Opposite of tie back
- 2-4 inches removed muscle
