Surgeon-Performed Ultrasound for Chronic Obstructive Sialadenitis Helps Predict Sialendoscopic Findings and Outcomes:

ObjectiveTo 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 DesignCase series with chart review.SettingThe practices of 2 academic sialendoscopy surgeons.Subjects and MethodsBetween 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.ResultsThe positive predictive value (PPV) and negative predictive value (NPV) of SP-US for identifying sialoliths intraoperati...
