This study is aimed to prove that a solid sialogogue can improve the defects of the liquid one and substitute it with no differences in the signal intensity. From January to August 2016, 60 patients with no salivary gland diseases were enrolled. The patients were divided into two groups as follows; a group with a liquid sialogogue and the other group with a solid sialogogue. MR images were acquired and signal intensities of the parotid glands were compared. As a result, the signal intensities of liquid and solid sialogogues showed no statistically significant differences($59.42{\pm}15.74$ and $61.80{\pm}13.99$, respectively) In conclusion, a solid sialogogue was verified to have no signal intensity differences from the liquid one while it could improve the defects of the liquid sialogogue.

Obstructive sialadenitis, one of the diseases that most frequently causes swelling and pain in the salivary glands, is mainly caused by structural obstructions. Sialolithiasis is the most frequent cause of the disease, and other causes include calculus formation, duct strictures, foreign bodies, and anatomical variations. Although there is a possibility that facial fillers directly block the salivary ducts, no cases of obstructive sialadenitis associated with them have been reported yet. We report the case of a 34-year-old female patient who complained of recurrent swelling and pain in the left buccal mucosa. She had undergone facial filler injection procedures on her facial area for cosmetic purposes several years before. Based on the findings of magnetic resonance imaging (MRI) and MR sialography, she was diagnosed with obstructive sialadenitis due to facial fillers. Through this case, we should remember to obtain a thorough history including filler treatments in the case of parotid gland swelling. We also suggest proper utilization of advanced imaging such as MRI in evaluating the location of facial fillers.
