  • Purpose: The purpose of this study was to assess cone-beam computed (CBCT) sialography imaging in the detection of different changes associated with lesions of salivary glands. Materials and Methods: This study consisted of 8 cases with signs and symptoms from salivary gland lesions. Conventional sialography using digital panoramic and lateral oblique radiographs and CBCT sialography were performed for each subject. The radiographs were evaluated by 3 radiologists independently of each other. The results were compared between conventional sialography and CBCT sialography in the evaluation of various lesions associated with the salivary glands. Results: There was an agreement between the radiologists in interpreting the lesions that affected salivary glands with both techniques. The detection of the presence of stones or filling defects, stenosis, ductal evagination, dilatation, and space occupying lesions was 83% for conventional sialography compared with CBCT sialography. CBCT sialography was superior to conventional sialography in revealing stones, stenosis, and strictures, especially in the second and third order branches. Conclusion: It would be advisable to perform CBCT sialography in cases of obstructive salivary gland diseases for better demonstration of the ductal system of the gland.

  • Chronic obstructive inflammatory disease of salivary glands is the most frequent disease of the salivary glands and is characterized by recurrent swelling and pain caused by pressure. Sialography is recommended for the diagnosis of obstructive sialadenitis to observe changes in duct morphology, such as stricture and dilatation. Intraductal irrigation using normal saline is a simple treatment for patients with chronic obstructive inflammatory disease by removing the microlith and mucous plugs in the duct. It can be used as a conservative treatment option for resolving the obstructive symptoms.

  • The purpose of this study was to aid in diagnosis of salivary gland disease by comparing the sialogram with the scintigram. In this study, 47 patients (52 glands) who had taken the sialography and the scintigraphy were examined. The result of two methods was compared with the clinical and operative diagnosis. The following results are obtained. 1. In inflammatory diseases of the salivary gland, the scintigraphy can be a valuable substitution for a sialography. 2. In inflammatory diseases of the salivary gland, we can get more informations in case of the combined use of the sialography and the scintigraphy. 3. In tumorous lesion of the salivary gland, the sialography is superior to the scintigraphy. But both methods are less valuable in diagnosing the extraglandular tumors.

  • Purpose: This report presents a procedure for performing power Doppler ultrasound-guided sialography using the phenomenon of increased blood flow and illustrates its application to practical patient cases. Materials and Methods: The salivary gland was scanned using ultrasound equipment (GE LOGIQ5 Expert® device; GE Medical Systems, Milwaukee, WI, USA) to identify pathological findings related to the patient's chief complaint. To identify the orifice of the main duct, it should be cannulated using a lacrimal dilator. After inserting the catheter into the cannulated main duct, the position of the catheter within the duct was confirmed by ultrasound. A contrast agent was injected until the patient felt fullness, and ultrasound (B-mode) was used to confirm whether the contrast agent filled the main canal and secondary and tertiary ducts. Then, power Doppler ultrasound was performed to determine whether the salivary gland had increased blood flow. Results: In 2 cases in this report, a power Doppler ultrasound scan showed a significant increase in blood flow after contrast medium injection, which was not observed on a preoperative scan. Conclusion: Power Doppler ultrasound was found to be a simple, safe, and effective tool for real-time sialography monitoring.

  • Sjögren syndrome is a chronic autoimmune inflammatory disease characterized by lymphocytic infiltration of exocrine glands, predominantly the parotid and lacrimal glands, thereby resulting in oral and ocular dryness. It has been reported to occur most frequently in women between 40 and 50 years of age. Sjögren syndrome has an insidious onset, is slowly progressive, and presents a wide range of clinical manifestations, leading to delays or challenges in the diagnosis. Early diagnosis of this condition is essential to prevent the associated complications that affect patients' quality of life. This report presents 3 cases of Sjögren syndrome in female patients aged between 40 and 75 years who presented with complaints of persistent dry mouth and burning sensation. The cases highlight the diagnostic value of 3-dimensional cone-beam computed tomographic sialography in the detection of salivary gland pathologies at an early stage.

  • 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.

  • The purpose of this study was to established the characteristic radiographic features in salivary gland diseases by means of sialography and scintigraphy. Sialograms and scintigrams with diseases of salivary gland were examined. In this group were 5 salivary stones, 14 sialadenitis, 17 Sjogren's syndromes and 8 benign tumors. The obtained results were as follows; 1. In the configuration of the shape of main duct, those revealed that modified curvilinear and curvilinear types were predominant in Sjogren's syndromes but reverse sigmoid and angular types were in sialolithiasis and sialadenitis combined with sialodochitis. 2. In the configuration of the course of main duct, those revealed that smooth types were predominant in sialadenitis and irregular types were predominant in Sjogren's syndromes and benign tumors and irregular types were seen in all salivary stones and sialadenitis combined with sialodochitis, 3. In the type of intraglandular pattern, those revealed that destructive changes of salivary duct system and parenchyma were severe in sialadenitis and salivary stones and predominantly severe in Sjogren's syndromes. 4. The function of salivary gland was decreased severely in Sjogren's syndrome. and also decrease in salivary stone and sialadenitis. In benign tumor, the uptake of radioisotope was not seen in lesion and the function of salivary gland decreased in its remaining normal parenchyma.

  • In Sjogren syndrome, abruptly decreased salivation and delayed lag time reveal that many acini cells are destructed and Lymphocytes infiltration is supposed as the main cause that makes dysfunction of salivation. In this case report, the biopsy of minor salivary glands is very useful diagnostic method of Sjogren's syndrome with sialometry,sialography, salivary gland scan.

  • Purpose: Obstructive and inflammatory disease often occurs in the major salivary glands, and no predictive treatment has yet been developed for this condition. The aim of this report was to introduce an intraductal irrigation procedure and to illustrate its application to practical patient cases. Materials and Methods: Two patients complaining of pain and swelling in the parotid gland during meals who underwent sialography were diagnosed as having sialodochitis with sialadenitis. Intraductal irrigation was then performed on the parotid gland on the side of the complaint. The irrigation procedure was conducted in the same manner as the sialography procedure, except that saline was used as the filling solution. Symptom severity was evaluated with a numerical rating scale (NRS) at the initial visit and a month after the irrigation. Results: The initial NRS value of patient 1 was 10. The value decreased to 6 and then to 0 after 2 irrigation procedures. The NRS value of patient 2 regarding the symptoms involving the left parotid gland decreased from 4-5 to 1 after 4 irrigation procedures performed at 1-month intervals. Conclusion: Intraductal irrigation of the salivary gland may be a simple, safe, and effective treatment option for patients with obstructive and inflammatory disease of the salivary gland that is capable of resolving their symptoms.
