Overview
Sialography may be helpful in the diagnosis of sialolithiasis. Findings on sialography suggestive of sialolithiasis include filling defect and the contrast agent not passing through the duct due to complete obstruction.
Other Imaging Findings
Conventional sialography may be helpful in the diagnosis of sialolithiasis. Findings on sialography suggestive of sialolithiasis include:[1][2]
- Filling defect within the duct
- In complete obstruction, contrast can not pass beyond the stone
Sialography is contraindicated in active infection of the involved gland.
Sialography is replaced by CT scan and ultrasound.
