Q

disphagia: causes and different locations

A

functional: idiopathic, myasthenia, brainstem lesion, intracranial.
structural: masses, mucocele (pharingeal), tyroglossal duct cysts, hyoid bone deformation

pharingeal dysphagia: multiple attemt to swallow, bolus not passing pharingeal constrictor

pharyngoesophageal dysphagia: normal bolus movement through pharynx, fail to pass through cricopharyngeal spinchter

Q

mandibular salivary gland anatomy

A

LATERAL: linguofacial.maxillary vein junction
MEDIAL: medial retropharingeal LN + larynx
CRANIAL: sublingual
VENTRAL: mandibular LN

17
Q

mandibular salivary gland duct: position + opening

A

beetween styloglossus and mylohyoideus

sublingual caruncole (lateral lingual frenulum)

18
Q

sublingual salivary gland duct: openings

A

POLYSTOMATIC: empty directly oral cavity

MONOSTOMATIC (major sublingual duct): courses alongside mandibular duct, exit sublingual caruncole

19
Q

what therapy usally produce improvement in sialoadenosis and sialoadenitis?

A

phenobarbital: 1-2 mg/kg PO BID

theoretically because of limbic epilepsy cause

20
Q

difference between sialoadenosis and sialoadenitis/necrotizing sialometaplasia

A

pain upon palpation and vomiting

21
Q

causes of sialocele

A

trauma
sialoliths
foreign bodies
neoplasia

22
Q

4 main presentation of sialocele

A

EXOPHTALMOS: zigomatic
LABORED BREATHING: Pharyngeal (sublingual-mandibular)
DYSPHAGIA: ranula (sublingual-rostral portion
INTERMANDIBULAR-CERVICAL SWELLING: multiple glands

23
Q

two approaches for sublingual-mandibular sialoadenectomy

A

ventral or lateral

24
Q

most common oral tumors in dogs

A

FOAMS:

fibrosarcoma, osteosarcoma, ameloblastoma anantomatoso, melanoma, squamous cell carcinoma

25
Q

classification of EPULIS

A

CAA-POF-FFH

canine achantomatous ameloblastoma: from odontogenic tissue
peripheral odontogenic fibroma: fibrous and ossifyinng epulides
focal fibrous hyperplasia: reactive lesion from irritation by plaque or calcuclus

26
Q

is it possible to remove mandibula, parotid and medial retropharingeal lymphnodes with a single approach?

A

YES: SMITH 1995

27
Q

what is the major artery to take care during a total mandibulectomy?

A

inferior alveolar artery if caudal mandibulectomy is performed

inferior alveolar artery has to be ligated if rostral mandibulactomy is performed in the mandibular canal

28
Q

major artery to take care during caudal maxillectomies

A

major palatine artery

29
Q

major artery to take care during caudal maxillectomies
