43
The palatine tonsils are contained within the ?
tonsillar fossa
44
What tissue do palatine tonsils contain?
Lymphoid
45
Blood to the tonsils is supplied by the ? artery?
tonsillar artery
46
Where does the tonsillar artery originate from?
Lingual a
47
In cats, where is the palatine tonsil located?
Same as dogs (tonsillar fossa)
48
In cats, where is the lingual tonsil located?
Base of tongue
49
In cats, where is the pharyngeal tonsil located?
on roof of nasopharynx.
50
In cats, where is the paraepiglottic tonsil located?
located craniolateral to the base of epiglottis.
51
Role of the tonsil?
To recognise, process and modulate an immunogenic response to antigens entering the oral and nasal cavity.
52
Where do the efferent lymphatics of the tonsils drain? (2)
To mandibular and retropharyngeal lymph nodes.
53
What disease is one of the most common causes of enlarged/everted tonsil?
Upper respiratory tract
54
What breed is enlarged/everted tonsils seen in?
BOAS
55
What age does primary tonsilitis effect?
Young - <1 year
56
What is seen on exam with tonsilitis?
Red + friable tonsils
57
Clinical signs of primary tonsilitis? (6)
Cough Gagging Dysphagia Fever Depression Anorexia
58

59
When is surgery recommended for tonsiltiits?
Recurrent signs
60
How common is tonsilitis in cats?
Rare
61
Most common neoplasia of canine tonsils?
SCC
62
How common and what is the most common tumour of feline tonsil?
RARE SCC
63
Met rate of SCC?
Highly
64
Treatment of tonsil SCC?
Bilateral tonsilectomy
65
Median survival time of SCC and tonsilectomy?
2mo
66
Tonsillectomy: How to approach?
The tonsil is grasped and removed from the tonsillar crypt. A stay suture is useful to assist with manipulation if necessary.
67
Tonsillectomy; once held; how to remove?
The base is ligated and transected – bleeding from the tonsillar artery can be a concern so suture ligation or electrocautery are recommended.
68
How to close tonsillar crypt after tonsillectomy?
The crypt mucosa is closed using 2M (3.0) or 1.5M (4.0) absorbable suture in a continuous pattern.
