TIPS: SIALOLITHIASIS vs SIALOSTENOSIS
1. Both cause pain and/or swelling after eating.
2. CT is useful for sialolithiasis; less so for sialostenosis
3. Sialolithiasis may cause a sensation of sand or gravel in the mouth.
4. Sialostenosis may leave a sour taste or mucus in the mouth.
5. Both can be treated with secretagogues to stimulate flow or saliva, or by milking (compressing the gland at first sign of pain or swelling). Stones often just pass, but may need to be removed surgically.
