Question 87 (part 2) · LDEK · Salivary gland diseases
Choose true statements regarding radiation-induced damage of salivary glands:
1) dose of around 10 Gy causes sudden and very painful edema of the salivary gland located in the area of irradiation;
2) dose of around 10 Gy causes dysfunction of salivary gland in 60 to 70%, which is reversible;
3) dose of around 60 to 70 Gy causes dysfunction of salivary gland up to 80%, which is reversible;
4) symptomatic treatment is implemented – artificial saliva, rinsing of the oral cavity with vitamin A and E solutions;
5) damage mechanism of salivary glands consists in damaging the parenchyma and extra salivary ducts.
Correct answer is:
2) dose of around 10 Gy causes dysfunction of salivary gland in 60 to 70%, which is reversible;
3) dose of around 60 to 70 Gy causes dysfunction of salivary gland up to 80%, which is reversible;
4) symptomatic treatment is implemented – artificial saliva, rinsing of the oral cavity with vitamin A and E solutions;
5) damage mechanism of salivary glands consists in damaging the parenchyma and extra salivary ducts.
Correct answer is:
- A. 1,2,4.
- B. 1,4.
- C. 2,3,5.
- D. 4,5.
- E. 1,3.
Hint
Distinguish the acute, reversible effects of low doses from the effect of full therapeutic doses, and recall which part of the gland is radiosensitive.
