Objectives To prospectively assess short‐term symptom change after sialendoscopy‐assisted salivary duct surgery (SASDS) for salivary duct stenosis. Study Design Prospective cohort study. Methods Patients with obstructive sialadenitis from duct stenosis completed the 20‐item Chronic Obstructive Sialadenitis Symptoms (COSS) Questionnaire (scored 0–100) prior to SASDS and 3 months postoperatively. Results Thirty glands in 19 patients with endoscopically confirmed salivary duct stenosis showed overall symptom improvement, with a mean COSS score reduction of 12.9 points (standard deviation [SD] 13.1) to a mean postoperative score of 25.1 (range 0–75.5) ( P < 0.001) with six (20%) glands (5 patients) achieving complete symptom resolution. Symptoms improved significantly for parotid glands (n = 20) by 16.6 points (SD 15.9) ( P < 0.0001). For distal duct stenoses (n = 25), significant symptom improvement was seen in cases treated with dilation only (n = 17; partial stenoses) with a mean 20.6 point COSS reduction (SD 19.0) ( P < 0.0005) and in cases treated with sialodochoplasty (n = 5; 4 complete, 1 partial stenosis) with a mean 13.8 point reduction (SD 4.7) ( P < 0.005). Symptom scores did not improve after SASDS in proximal stenoses (n = 3) and distal stenoses cases not amenable to treatment (n = 3). Conclusion SASDS for salivary duct stenosis often can improve obstructive salivary symptoms; however, many patients report persistent symptoms after surgery. Partial duct stenoses or distal duct stenoses are associated with the greatest improvements in COSS scores after SASDS. Level of Evidence 4. Laryngoscope , 127:2770–2776, 2017
