Abstract
The "double tongue sign" is a characteristic finding in patients with Ludwig's angina, a potentially life-threatening infection due to airway compromise. Management primarily focuses on early airway protection and antibiotic administration. Submandibular sialolithiasis, on the other hand, could present with the double tongue sign without symptoms suggestive of airway involvement. Unlike Ludwig's angina, conservative treatment is usually the first-line approach for sialolithiasis. The importance of rapidly recognizing and distinguishing between the 2 conditions is emphasized through effective triage and risk stratification, particularly in rural areas where physicians are not readily available.

A comparative study of three-dimensional cone beam computed tomographic sialography and ultrasonography in the detection of non-tumoral salivary duct diseases. Dentomaxillofac Radiol 2023; 52:20220371. [PMID: 37052400 PMCID: PMC10304847 DOI: 10.1259/dmfr.20220371] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/07/2022] [Revised: 02/23/2023] [Accepted: 02/27/2023] [Indexed: 04/14/2023] Open
Abstract
OBJECTIVES To compare the overall diagnostic outcomes of 3D-CBCT sialography and ultrasonography (US) in the detection of sialolithiasis, ductal dilatation, and ductal stenosis. METHODS This retrospective monocentric study compared the two imaging modalities carried out in the same patients referred for salivary symptoms of the parotid and submandibular glands. The primary endpoint was the capacity of the imaging procedure to diagnose a lesion. The secondary objectives were the detection rates according to the type of lesion, analysis of the causes of failure, and the parameters of radiation exposure and safety (for 3D-CBCT sialography). RESULTS Of the 236 patients who received a 3D-CBCT sialography in our institution, 157 were ultimately included in the per-protocol analysis. 3D-CBCT sialography allowed detection of ductal lesions in 113 patients versus 86 with US. The two imaging modalities yielded congruent interpretations in 104 out of 157 subjects (66.2%). Higher sensitivity and negative predictive value were observed with 3D-CBCT sialography compared with US, irrespective of the lesions studied: 0.85 vs 0.65 and 0.70 vs 0.44, respectively. Regarding the sialolithiasis, both 3D-CBCT sialography and US allowed identification of lesions with high sensitivity and negative predictive value (0.80 vs 0.75 and 0.88 vs 0.78, respectively). CONCLUSIONS US remains the first-line examination for exploration of the salivary lesions. 3D-CBCT sialography is an alternative in case of inconclusive US, and prior to any endoscopic procedure.

Abstract
Objective The study aimed to analyze the formation process of submandibular stones based on the theory of biological mineralization and inorganic crystal structure variation. Study design From January 2021 to December 2021, patients with submandibular stones treated in the Affiliated Hospital of Stomatology, Sun Yat-sen University (Guangzhou, China) were selected. According to the criterion of maximum transverse diameter ≥3 mm, a total of five submandibular stones meeting the requirement were included. After the surface of sample stones were washed, they were cut along the maximum transverse diameter. Next, the study employed Scanning Electron Microscope (SEM), Energy Dispersive X-ray Spectroscopy (EDS), and polycrystalline X-ray Diffraction (XRD) to analyze the composition and structure of submandibular stones. Results Five submandibular stones were included. The organic and inorganic compounds showed a rhythmic or irregular distribution. Submandibular stones were highly occupied with carbon (C), oxygen (O), calcium (Ca), and phosphorus (P). Hydroxyapatite (HAP) was the primary inorganic component. In addition, the precursor of HAP, namely Amorphous Calcium Phosphate (ACP), was also found. Tetrahedral Substitution Index (TSI) and Ca/P ratio reflected the degree of structural variation in HAP crystal, which fluctuated from 5.62-90.71 and 1.10-1.35, respectively. Conclusions The development of submandibular stones was influenced by inorganic crystals' chemical and structural variation as well as the organics' regulation towards the inorganic. The isomorphic substitution was accompanied by the occurrence of inorganic crystals, resulting in the crystal structure change. Organics might influence the appearance, aggregation, and mineralization of HAP during its formation.

Abstract
OBJECTIVE Ultrasound (US) and sialendoscopy (SE) are routinely used in patients presenting with sialolithiasis in the submandibular (SMG) and parotid gland (PG). The objective was to assess the value of the simultaneous application of US and SE in the management of sialolithiasis. STUDY DESIGN Retrospective study. SETTING Tertiary referral center for salivary gland diseases. PARTICIPANTS Patients in whom US and SE as single investigation tools were neither conclusive nor useful in the management of sialolithiasis were investigated using both methods simultaneously (simUS + SE). MAIN OUTCOME MEASURES Establishment of the final diagnosis and/or contribution to the planning/performing of treatment in sialolithiasis. RESULTS 74 patients were examined by simUS + SE (58.1 % SMG and 41.9 % PG). In all patients (unclear) hyperechoic reflexes were assessed and/or localized by SE-controlled US navigation. 68.9 % of the patients were investigated for diagnostic or differential-diagnostic reasons including distinguishing extraductal from intraductal calcifications and/or to exclude residual stones after therapy. In 52.7 % simUS + SE was used to plan and/or perform further treatment, in 20.3 % to enable performing a combined approach (all PG) and in 29.7 % to evaluate and plan the most adequate therapy (mainly intraductal vs. extracorporeal shock wave lithotripsy, 68.2 % of these SMG). In two cases SE-controlled and US-guided stone extraction was performed. CONCLUSION SimUS + SE is an innovative approach which proved to be very useful in managing sialolithiasis. It added valuable information regarding the establishment of a diagnosis or differential diagnosis, planning and performing the most adequate treatment, intraoperative control of therapy and postoperative follow-up.

Abstract
OBJECTIVES The purpose of the present scoping review was to determine the contribution of ultrasound images in the diagnosis of inflammatory and obstructive diseases of the major salivary glands (MSGs). METHODS A search of studies of ultrasonographic assessments of human samples was performed in several electronic databases and grey literature up to July 2021. The extracted data were the examined MSG; the diagnostic value of ultrasound (sensibility, specificity, positive- and negative predictive value, accuracy); features of lesions, including number, echogenicity, echotexture, form, margins, size, posterior acoustic aspect, and location; and related clinical information, such as swelling, palpation, sensible to pain, salivation, lymph nodes, recurrence, duration, and causes. RESULTS After verifying the eligibility criteria, 90 articles focused on detecting inflammatory, and obstructive diseases of the MSG were gathered, with variable study designs and size samples. A wide variety of pathologies were assessed, including sialolitiasis (n = 45), acute sialadenitis (n = 30), chronic sialadenitis (n = 25), granulamatous diseases (n = 15), Kuttner's tumor (n = 11), juvenile recurrent parotitis (n = 9), abscess (n = 7), post-radiotherapy sialadenitis (n = 6), sialadenosis (n = 9), abscess (n = 7), IgG4-related disease sialadenitis (n = 5), HIV-sialadenitis (n = 4), obstructive sialadenitis (n = 3), iodinated contrast-induced sialadenitis (n = 2), and pneumoparotitis (n = 1). Most studies were case reports or series of cases. Few studies exhibited data about the accuracy of ultrasound in detecting MSG diseases. CONCLUSIONS The present scoping review concluded that ultrasound aspects of different MSG pathologies are similar but contribute to their differential diagnosis and can be considered as a valuable initial method for assessing the MSG of adults and children.

Abstract
OBJECTIVES We hypothesized that ultrasonography for salivary gland stone detection would have a diagnostic accuracy similar to that confirmed by sialendoscopy, sialography, or surgery. Therefore, we evaluated the diagnostic characteristics of ultrasonography in terms of submandibular and parotid stone detection compared to confirmatory methods. METHODS We searched PubMed, Embase, the Web of Science, SCOPUS, and the Cochrane database to October 31, 2021. The risk of bias was evaluated using the QADAS-2 tool. RESULTS Ten studies involving 1393 patients were included in the analysis. The diagnostic odds ratio of ultrasonography was 162.6013 (95% confidence interval [CI] [53.9883; 489.7208] and I2 value 81.0%). The area under the summary receiver operating characteristic curve was 0.963. The sensitivity, specificity, negative predictive value, and positive predictive value were 0.8992 (95% CI [0.8534; 0.9318]; I2 = 79.9%), 0.9664 (95% CI [0.9290; 0.9844], I2 = 65.6%), 0.8076 (95% CI [0.7256; 0.8694]; I2 = 80.4%), and 0.9853 (95% CI [0.9629; 0.9943]; I2 = 77.4%), respectively. However, high-level among-study heterogeneity (I2 ≥ 50%) was evident, attributable to the inclusion of different glands. On subgroup analysis, significant differences in the negative predictive values (parotid gland only [0.9392], submandibular gland only [0.6718], and parotid and submandibular glands [0.8105]) were apparent. We found no significant among-study difference in the sensitivity, specificity, positive predictive value, or diagnostic odds ratio (P > .05). CONCLUSION Ultrasonography usefully detects submandibular and parotid gland stones. Ultrasonography of the parotid gland was associated with the highest diagnostic accuracy, but further clinical studies are needed. LEVEL OF EVIDENCE NA Laryngoscope, 2022.

Abstract
OBJECTIVE This study aimed to compare the performance of 3 deep learning models, including a model constructed with the transfer learning method, in detecting submandibular gland sialoliths on panoramic radiographs. STUDY DESIGN We used data from 2 institutions (A and B) to create the models for use in institution B. In total, 224 panoramic radiographs with sialoliths were used. Model 1 was created using data from institution A only, model 2 was created using combined data from institutions A and B, and model 3 was created using the transfer learning method by having model 1 transferred and trained in various learning epochs using data from institution B. These models were tested and compared in their detection performance using testing data sets from institution B. RESULTS Model 2 and model 3 with 300 epochs performed equally well and yielded the highest detection rates (recall: sensitivity of 85%, precision: positive predictive value of 100%, and F measure of 91.9%) for sialoliths on panoramic radiographs. CONCLUSION The results of this study suggest that use of the transfer learning method with an appropriate number of epochs may be an alternative to sharing patient personal data among institutions.

Abstract
Background: Ultrasound is established as a diagnostic tool in salivary glands for obstructive diseases such as sialolithiasis and tumors. Concerning inflammatory diseases and in non-sialolithiasis-caused obstruction, much fewer data are available. In recent years, technical development has allowed a better assessment of the gland parenchyma, and knowledge about intraductal pathologies has increased considerably, which has provided new insights and a new interpretation of ultrasound findings. Objectives: To provide a comprehensive review of the literature that includes our own experiences and to point out the state of the art in ultrasound in the diagnostics of inflammatory and obstructive salivary gland diseases, taking adequate techniques and recent technical developments into consideration. Data sources and study eligibility criteria: A systematic literature search was performed in Pubmed using various specific key words. Results: According to the literature results, including our own experiences, ultrasound is of value in up to >90% of cases presenting with inflammatory and/or obstructive diseases. Technical developments (e.g., elastography) and the application of modified ultrasound techniques (e.g., transoral ultrasound) have contributed to these results. Today, ultrasound is considered a first-line diagnostic tool in these diseases. However, in some inflammatory diseases, the final diagnosis can be made only after inclusion of the anamnesis, clinical symptoms, serologic blood tests, or histopathologic investigation. Conclusions: Ultrasound can be considered as a first-line diagnostic tool in obstructive and inflammatory salivary gland diseases. In obstructive diseases, it may be sufficient for diagnostics in >90% of cases. In inflammatory diseases, ultrasound is at least an excellent screening method and can be used to establish the diagnosis in cases of an early suspicion. In all diseases ultrasound can contribute to better management and can be used for monitoring during follow-up.

Abstract
OBJECTIVE/HYPOTHESIS Current literature has confirmed the benefits of sialendoscopy for the treatment of juvenile recurrent parotitis (JRP). However, this procedure is often performed unilaterally, although the disease can affect both sides. This article investigated the clinical course of the contralateral parotid (CL) gland in children requiring unilateral sialendoscopy with the goal of clarifying the necessity of primary bilateral sialendoscopy. STUDY DESIGN Prospective cohort study in a tertiary center. METHODS Over an eight-year period, 77 children with JRP underwent unilateral sialendoscopy. We observed the clinical course of the CL parotid over a minimum follow-up period of 24 months. New episodes of sialadenitis were recorded on both sides along with the need for a second sialendoscopy. These data were correlated with the preoperative symptoms of the contralateral side as well as ultrasound (U/S) findings at baseline assessment. RESULTS In total, six children required sialendoscopy on the CL side (7.8%), 62 children remained asymptomatic or with scarce swellings (80.5%), and nine children improved (11.7%). The preoperative U/S findings on the CL side positively correlated with the number of postoperative swellings. The proportion of children needing CL sialendoscopy was higher (21.4%) among children needing a second sialendoscopy on the operated side. CONCLUSIONS In the long term, the vast majority of children needing unilateral sialendoscopy do not require similar treatment of the CL parotid gland. However, a history of bilateral swellings along with U/S findings of parenchymal disorganization on the CL side significantly increases the risk of needing further sialendoscopy at a later time.

Abstract
OBJECTIVES The present study was developed to evaluate the accuracy of in vivo ultrasound sizing for parotid and submandibular salivary gland calculi, as compared with ex vivo pathology sizing with a standard plastic ruler after extraction. STUDY DESIGN Retrospective chart review. SETTING Ultrasound is frequently used to size salivary calculi and make treatment decisions, but the accuracy of measurements from this modality has not been validated. SUBJECTS AND METHODS We evaluated and reviewed the charts and ultrasound examinations of 167 patients who underwent procedures for the treatment of sialolithiasis involving the parotid and submandibular glands. US examinations were performed between 2009 and 2016 in a tertiary-level hospital setting by the senior author. Measurements were collected from ultrasound evaluation before sialolithotomy, and pathology measurements were taken after removal. Ultrasound measurements in millimeters were compared with the measurements collected with a ruler. The differences were calculated and compared. RESULTS A total of 167 calculi measurements were compared. Good concurrent validity between pathology and ultrasound measurements was suggested by a Pearson correlation of 0.92 (95% CI, 0.887-0.937). On Bland-Altman plot, correlation of the difference between US and pathology measurements showed a mean difference of 0.095 mm (95% CI, -0.19 to 0.38 mm) with a limit of agreement ranging from -3.59 mm (95% CI, -3.84 to -3.34 mm) to +3.78 mm (95% CI, +3.53 to +4.03 mm). CONCLUSIONS Ultrasound is an accurate, relatively precise, and minimally invasive imaging tool for salivary gland sialolithiasis. Preoperative size of calculi can be used to guide management and clinical decision making. LEVEL OF EVIDENCE 2C.

Abstract
OBJECTIVE A tonsillolith is a concretion of the tonsillar crypt. The aim of this retrospective study was to compare panoramic radiography (PR) and cone-beam computed tomography (CBCT) for the detection of tonsilloliths. MATERIALS AND METHODS The CBCT images of 527 patients with maxillofacial volume were evaluated retrospectively. Of these, 175 patients (81 females, 94 males; mean age 51.05 years) had unilateral or bilateral tonsilloliths. In total, 151 of them (67 females, 84 males; mean age, 51.03 years) had PR images performed in the same period and were included in the study. The PR images were examined to ascertain whether known tonsilloliths (from CBCT images) could be detected. The location (unilateral; left or right and bilateral), size, and number of the tonsilloliths were examined on both CBCT and PR images. Descriptive analysis, Spearman's rho correlation coefficient, and χ2 tests were used for the statistical analysis. RESULTS The detection rate of tonsillolith was 33.2% on CBCT images. Only 51.4% of the tonsilloliths detected on CBCT were evaluated by PR; the correlation between CBCT and PR was found to be significant (Spearman's r = 0.399, p = 0.000). PR was not adequate to detect tonsilloliths 1 mm or smaller in size. All the calcifications larger than 5 mm were detected on PR images. CONCLUSION The results of this study showed that more than half of the tonsilloliths observed in CBCT were also detected in PR. Tonsilloliths larger than 2 mm were more likely to be detected on PR images.

Abstract
Transcutaneous ultrasound (TCUS) is an accepted diagnostic method in salivary gland diseases. However, sparse data are available on the use of transoral ultrasound (TOUS) in sialadenopathies. One hundred five patients presenting with various obstructive sialadenopathies were examined using TOUS and TCUS. Ultrasound findings were validated by direct visualization in subsequent sialendoscopy examinations. By TOUS, but not by TCUS, all patients with sialolithiasis (70/105) could be identified and virtually all concrements, even very small ones, were detected and distinguished from artifacts. Ductal stenoses (16/105) could be correctly differentiated from sialoliths, and exceptional insights into the delicate anatomy of parotid duct stenoses were gained. TOUS provided detailed information on other space-occupying lesions (14/105) and circumvented the method-related diagnostic weaknesses of TCUS. As a valuable tool in the diagnosis of obstructive sialadenopathies, TOUS seems superior to TCUS in pathologies involving the distal parotid duct, the submandibular duct system and the floor of the mouth.

Abstract
OBJECTIVES Sialolithiasis is the most common cause of chronic sialadenitis of the submandibular gland (SMG). Symptomatic superficial lobe stones are often treated by submandibulectomy. A gland preserving operation allows for transoral stone removal through endoscopically assisted sialolithotomy. Herein, we provide clinical and sonographical follow-up data in patients who underwent sialolithotomy under general anesthesia. MATERIALS AND METHODS Sixty patients treated at the Department of Oral and Maxillofacial Surgery at Düsseldorf University Hospital for superficial lobe sialolithiasis of SMG were included in this study. All received transoral sialolithotomy under general anesthesia. Follow-up was conducted via standardized patient questionnaires, clinical examination, and B-mode and color Doppler sonography. RESULTS Mean patient age was 48.9 years. 56.6% of right and 43.4% of left SMG were affected. Mean follow-up was 45 months. Fifty-five of 59 detected stones could be removed. Mean operation time was 71 min. 3.3% of patients reported recurrent episodes of postoperative pain and 10% felt recurrent episodes of gland swelling. Persistent postoperative lingual nerve hypesthesia was described in one patient. No facial nerve damages occurred. Salivary flow rates remained reduced in most of the affected glands upon stone removal. Sonographical follow-up data of the previously affected SMG after intraoral endoscopy-assisted sialolithotomy showed a regular gland size in 70.8% of cases, a parenchyma free of inflammation in 93.8%, and without signs of fibrosis in 72.9% of cases. 68.7% of patients showed a regular structure of Wharton's duct at time of follow-up. In total, 89.6% of patients were diagnosed stone-free within both glands on follow-up. No case required subsequent submandibulectomy. CONCLUSIONS Sialolithotomy of Wharton's duct for removal of stones from the SMG's superficial lobe is a promising alternative to submandibulectomy. CLINICAL RELEVANCE Reduction of postoperative morbidity through endoscopically assisted sialolithotomy for removal of superficial lobe stones from SMG. TRIAL REGISTRATION Ethics Committee of Heinrich-Heine-University Düsseldorf (no. 5586).

Abstract
Objective To assess the value of ultrasound, if indicated, supplemented by sialendoscopy, in the diagnosis of sialolithiasis. Study Design Retrospective study. Setting Referring center for salivary gland diseases. Subjects and Methods All patients who presented with a suspected diagnosis of obstructive sialopathy between January 2011 and April 2017 and had not undergone any treatment were retrospectively evaluated. A total of 2052 patients and 2277 glands were included in the study. Ultrasound examinations were carried out initially and followed by sialendoscopy in all cases. Direct demonstration of sialothiasis by sialendoscopy, transoral ductal surgery, and discharge of concrements/observation of fragments during sialendoscopy after extracorporeal shock-wave lithotripsy were regarded as definitive evidence of sialolithiasis. Results Ultrasound had an accuracy, sensitivity, specificity, positive predictive value, and negative predictive value of 94.77%, 94.91%, 94.57%, 96.14%, and 92.89%, respectively, for the diagnosis of sialolithiasis. All false-positive findings were correctly diagnosed, and in all false-negative findings, stones/fragments were visualized by sialendoscopy. Over 95% of the false-negative findings in major salivary glands (64/67) had visible ductal dilation in sonography, and in 73.1%, the stones not detected on ultrasound were located in the distal part of the duct, which is easily accessible with the sialendoscope. Conclusion This study shows that sialolithiasis can be diagnosed using ultrasonography with a high degree of certainty. If supplemented by sialendoscopy, the correct diagnosis could be established in virtually all cases of sialolithiasis. Ultrasound supplemented by sialendoscopy has the potential to serve as an alternative diagnostic standard in the future.

Abstract
AbstractObjective:The imaging of stones in the salivary glands and ducts poses a challenge, even to experienced ultrasound examiners. This study investigated whether the ‘twinkling artefact’, which occurs at internal calcific foci during Doppler ultrasound examinations, is useful for detecting salivary gland stones.Methods:In a model test, 20 salivary stones were analysedin vitro, via Doppler ultrasound, with regard to their representability and the triggering of the twinkling artefact. In a follow-up study, 28 patients with sialolithiasis and food-related large salivary gland swellings were examined, using both power and colour Doppler modes, with regard to the twinkling artefact. All ultrasound examinations were performed by an experienced examiner and retrospectively graded by two experienced sonographers.Results:All stones could reliably be detected using the twinkling artefact in the model test. Twenty-seven of 28 salivary stones (96 per cent) also showed twinklingin vivo, during patient assessment. The power Doppler mode showed a significantly higher intensity level of twinkling than the colour Doppler mode (p< 0.0001).Conclusion:The twinkling artefact is a very reliable sign for the diagnosis of sialolithiasis. Power Doppler is superior to colour Doppler for detection of the twinkling artefact.

Abstract
Purpose Sialolithiasis is one of the most prevalent large obstructive disorders of the submandibular glands. The aim of this study was to investigate submandibular sialolithiasis with computed tomography (CT) and scintigraphy, with a particular focus on the relationship between CT values of the submandibular glands and their excretion rate. Materials and Methods Fifteen patients with submandibular sialolithiasis who underwent CT and salivary gland scintigraphy were included in this study. The relationship between the CT values of submandibular glands with and without sialoliths and salivary gland excretion measured using salivary gland scintigraphy was statistically analyzed. Dynamic images were recorded on the computer at 1 frame per 20 seconds. The salivary gland excretion fraction was defined as A (before stimulation test [counts/frame]) / B(after stimulation test [counts/frame]) using time-activity curves. Results The CT values in the submandibular glands with and without sialoliths was 9.9±44.9 Hounsfield units (HU) and 34.2±21.8 HU, respectively (P=.233). Regarding the salivary gland excretion fraction using scintigraphy, the A/B value in the submandibular glands with sialoliths (1.09±0.23) was significantly lower than in the submandibular glands without sialoliths (1.99±0.57, P=.000). Conclusion Assessments of the CT values and the salivary gland excretion fraction using scintigraphy in the submandibular glands seem to be useful tools evaluating submandibular sialolithiasis.

Abstract
OBJECTIVES The aim of this study was to assess the effectiveness of sonography for diagnosing sialolithiasis in comparison with the existing reference standard of direct identification of a stone. METHODS A total of 659 glands with signs of obstructive sialadenopathy were evaluated retrospectively. Sonographic examinations of the large head salivary glands had been performed initially in all cases. Direct depiction of a stone during sialoendoscopy or transoral ductal surgery or observation of stone fragmentation with discharge of concrements after extracorporeal shock wave lithotripsy, was regarded as definitive evidence and as the reference standard for the presence of sialolithiasis. The sonographic results were compared with those for direct identification of stones. RESULTS The sensitivity of sonography was 94.7%, with specificity of 97.4%, a positive predictive value of 99.4%, and a negative predictive value of 79.6%. Stones that were not diagnosed correctly on sonography were most often located in the distal area of the duct. CONCLUSIONS These results show that sialolithiasis can be diagnosed by sonography with a high degree of certainty. Sonography thus appears to be highly appropriate as the examination method of choice.

Abstract
Objective To determine the accuracy of surgeon-performed ultrasound (SP-US) features for predicting intraoperative sialendoscopic findings and to correlate ultrasound features with short-term symptomatic outcomes following sialendoscopy-assisted salivary duct surgery (SASDS). Study Design Case series with chart review. Setting The practices of 2 academic sialendoscopy surgeons. Subjects and Methods Between February 2014 and September 2015, 82 patients with 105 symptomatic glands underwent SASDS, of whom 56 patients (75 glands) met inclusion criteria. SP-US and sialendoscopic findings were reviewed for patients with chronic obstructive sialadenitis who underwent SASDS and who had been prospectively evaluated with the University of California–San Francisco Chronic Obstructive Sialadenitis Symptoms (COSS) questionnaire (scored 0-100) administered preoperatively and 3 months postoperatively. Results The positive predictive value (PPV) and negative predictive value (NPV) of SP-US for identifying sialoliths intraoperatively were 94% (33/35) and 91% (39/43), respectively. Of glands with sialoliths on SP-US, 97% (34/35) had complete symptom resolution (COSS ≤10) after SASDS. The PPV and NPV of salivary duct dilation on SP-US for finding a corresponding stenosis on sialendoscopy were 93% (14/15) and 50% (14/28), respectively. Nonsialolith SP-US features with the highest PPV for complete or partial symptom resolution (COSS ≤25) following SASDS included distal duct dilation of all glands (86%; 6/7) and dilation of both distal and proximal parotid ducts (75%; 6/8). Conclusion SP-US has high accuracy for ruling in and ruling out sialoliths, as well as for ruling in but not for necessarily ruling out stenosis presence and location. Ultrasound is helpful in estimating degree of short-term symptom response following SASDS.

Abstract
Objective To determine the accuracy of the 2 most utilized imaging modalities in obstructive sialadenitis secondary to sialolithiasis—computed tomography (CT) and ultrasonography (US)—using sialendoscopic findings as a comparison standard. To review the impact of CT and US on the management of sialolithiasis managed with sialendoscopy alone and through combined approaches. Study Design Retrospective cohort study. Setting Quaternary academic referral center. Subjects and Methods All cases of patients undergoing sialendoscopy by a single surgeon for suspected parotid and submandibular gland pathology between the October 2013 and April 2016 were reviewed. Results Sixty-eight patients were in this cohort, of whom 44 underwent US, CT, and sialendoscopy; 20 underwent CT and sialendoscopy only; and 4 underwent US and sialendoscopy only. The sensitivity and specificity were 65% and 80% for US and 98% and 88% for CT, respectively. These 68 patients had 84 total stones addressed, with 79 being removed and 5 remaining in situ. The methods of stone removal were sialendoscopy alone (34 stones), open transoral approaches (36 stones), and an external approach: transcervical for submandibular and transfacial for parotid (11 stones). Conclusion US had a lower sensitivity (65%) than what has been reported in the literature (70%-94%), and the majority of missed stones were anterior Wharton’s duct stones. These sialoliths were likely missed due to an incomplete examination. US and CT were complementary in this study, and the findings suggest that both modalities can be utilized to optimize the outcome of sialendoscopy and combined approaches.

Abstract
Sialolithiasis is a frequent disorder affecting the salivary glands. The incidence rate (IR) has been reported to be 2.9-5.5 per 100,000 person-years, but all previous studies have been based on selected hospital data. In this study, we conducted a population-based study evaluating the IR of sialolithiasis and the IR variation according to age, gender and geography in Denmark. We included data from hospitals as well as from private ear, nose and throat (ENT) clinics. The study was based on registry data on all sialolithiasis cases in Denmark between 2003 and 2009 extracted from the Danish National Patient Registry (hospital cohort) and the Danish Regions Centre for Healthcare Statistics (private ENT clinic cohort). To validate the diagnosis, the proportion of visually confirmed cases was estimated based on patient records from subsamples of the two cohorts. The IR was 7.27 and 14.10 per 100,000 person-years based on visually confirmed cases only and on all cases, respectively. The highest IR was observed among 60- to 70-year-olds, in the North Denmark region and among females. In the validation subsamples, 35% of assumed sialoliths were visually confirmed in the private ENT clinic cohort and 59% in the hospital cohort. In this first population-based study of IR on sialolithiasis, we found a substantially higher IR. With respect to both visually confirmed cases and all cases, this is higher than previously reported from studies based on selected hospital data.

Abstract
Purpose The aim of this study was to assess and compare the diagnostic performance of panoramic and occlusal radiographs in detecting submandibular sialoliths. Materials and Methods A total of 40 patients (20 cases and 20 controls) were included in this retrospective study. Cases were defined as subjects with a submandibular sialolith confirmed by computed tomography (CT), whereas controls did not have any submandibular calcifications. Three observers with different expertise levels assessed panoramic and occlusal radiographs of all subjects for the presence of sialoliths. Intraobserver and interobserver agreement were assessed using the kappa test. Sensitivity, specificity, accuracy, positive and negative predictive values, and the diagnostic odds ratio of panoramic and occlusal radiographs in screening for submandibular sialoliths were calculated for each observer. Results The sensitivity and specificity values for occlusal and panoramic radiographs all ranged from 80% to 100%. The lowest values of sensitivity and specificity observed among the observers were 82.6% and 80%, respectively (P=0.001). Intraobserver and interobserver agreement were higher for occlusal radiographs than for panoramic radiographs, although panoramic radiographs demonstrated a higher overall accuracy. Conclusion Both panoramic and occlusal radiographic techniques displayed satisfactory diagnostic performance and should be considered before using a CT scan to detect submandibular sialoliths.
