Head and Neck I Note Card Set Flashcards
salivary gland found in cats but not in dogs
molar
salivary duct opening caudal to the upper 4th premolar
parotid papilla
salivary duct opening caudal to the parotid papilla
zygomatic ducts (major and minor)
salivary duct opening for the mandibular and sublingual glands (may share a common opening)
sublingual caruncle
contrast radiography of the salivary system
sialography
subcutaneous (or submucosal) accumulation of saliva within a nonepithelial, nonsecretory lining
sialocele
most common dz of the salivary system in dogs and cats
sialocele (salivary mucocele)
salivary gland most commonly affected with sialocele
sublingual
the ______ portion of the sublingual salivary gland is the portion most often associated with sialocele
rostral (polystomatic)
________ is intermandibular or cervically located sialocele; most common accumulation site
cervical mucocele
________ is a sublingually located sialocele
ranula
________ is a pharyngeal wall located sialocele; least common accumulation site
pharyngeal mucocele
_______ gland mucocele causes periorbital accumulation of saliva; can lead to exophthalmos
zygomatic
salivary gland always removed with the sublingual gland
mandibular
to determine which side a sialocele is originating from, place the animal in ______ recumbancy and see which side the bulk of the swelling falls to
dorsal
ranula is typically a ____lateral process and can be used to determine whether a left or right salivary gland is the cause of the problem
uni
do salivary gland ducts need to be ligated during sx?
no
recurrence of sialocele after sublingual gland resection is typically d/t _______
inadequate excision
parotid fistula is thought to occur as a result of ______ to the parotid duct
trauma
tx of partoid fistula is __________ proximal to the defect that is causing the fistula
parotid duct ligation
parotid duct ligation to treat parotid fistula leads to ________ of the gland
atrophy
salivary duct stones
sialoliths
gland most commonly affected with sialoliths
parotid
sialoliths are removed through _____ incision over the duct at the site of the sialolith
oral
inflammation of salivary glands that can be primary or secondary to trauma or systemic viral infection
sialadenitis
salivary gland most commonly affected by sialadenitis; can lead to retrobulbar abscess
zygomatic
tx for canine necrotizing sialometaplasia
sx and phenobarb
breed disposition to canine necrotizing sialometaplasia
terriers
painful inflammation of salivary gland leading to rapid increase in mandibular gland size w/in its tight capsule, resulting in necrosis
CNS (canine necrotizing sialometaplasia)
gland affected by canine necrotizing sialometaplasia
mandibular
nonpainful enlargement of mandibular or zygomatic salivary glands
canine sialadenosis
canine sialadenosis is theorized to be d/t increased _________ activity that induces excessive production of saliva
parasympathetic
canine sialadenosis of the _______ gland can lead to exophthalmos
zygomatic
tx for canine sialadenosis
phenobarb
breed predisposed to salivary gland neoplasia
spaniels
glands most commonly affected by salivary gland neoplasia
parotid, mandibular
traditional approach to mandibular and sublingual salivary gland excision is a ______ incision just below the mandible
lateral
