48. Chronic Inflammation Of Salivary Glands Flashcards
1
Q
Primary characteristics of sialadenitis
A
- Painful swelling of the affected salivary gland
- Can affect large and small glands
- If large=> more extensive clinical symptoms
2
Q
Factors contributing to sialadenitis
A
- General factors=>Lower general resistance and immunity
- Local factors=>Changes in saliva secretion and tract system
3
Q
Main differences between acute and chronic sialadenitis
A
- Acute sialadenitis=> bacterial and viral infections
- Chronic sialadenitis=>secretion disturbances and immunopathologic reactions
Chronic Sialadenitis- pathogens rarely observed in microbiology, making antibiotic treatment generally ineffective
4
Q
Characteristics of chronic bacterial sialadenitis
A
- Mostly affects parotid gland
- Secondary development=> acute purulent inflammation, stone formation, or radiotherapy complications
- Painful, recurrent swelling=>
- Decreased saliva flow
5
Q
Chronic bacterial sialadenitis treatment
A
- Same as Acute bacterial sialadenitis
- Gland removal or radiotherapy =>if recurrences occur
6
Q
Necrotizing sialometaplasia
A
- Reactive, nonneoplastic inflammatory process=>
- Minor salivary glands of palate
- Origin is unclear=>vascular infarction of the salivary gland lobules.
-Can also occur in minor salivary glands in any location
7
Q
Clinical features of necrotizing sialometaplasia
A
- Large (1 to 4 cm), deeply ulcerated areas
- Lateral to the palatal midline and near the junction of the hard and soft palate
- Unilateral but sometimes be bilateral
- Prodromal flu-like illness before the onset of ulceration
Ulcers may or may not be painful
8
Q
Why its important to correctly diagnose necrotizing sialometaplasia
A
- Can resemble carcinoma=> diagnosis made by experienced oral surgeon and pathologist
- Misdiagnosis =>unnecessary and extensive surgical resection
- Regress spontaneously within 6 to 10 weeks after their onset=> do not require surgical management
