Management of Chronic Sialadenitis due to Sjogren’s Syndrome and Radioactive Iodine Therapy Using Sialendoscopy

Abstract

<b><i>Introduction:</i></b> Sialendoscopy is a minimally invasive technique for the management of salivary gland disease. This work characterizes its utility for treating chronic sialadenitis due to Sjogren’s syndrome and radioactive iodine (RAI) therapy. <b><i>Methods:</i></b> A single-center, retrospective review of patients undergoing sialendoscopy between March 2013 and May 2019 for the treatment of chronic sialadenitis due to Sjogren’s or prior RAI therapy was performed. <b><i>Results:</i></b> Thirty-four patients with Sjogren’s and 25 patients who received RAI were identified, undergoing a total of 86 procedures. Median age at presentation was 53 years with mean follow-up time of 14.3 months. Seventy-two procedures were performed on the parotid gland, four on the submandibular gland, and ten on both glands. Corticosteroid injection and duct dilation were performed most commonly. Sixteen patients required repeat procedure. All patients were symptomatically improved at follow-up visit. <b><i>Discussion/Conclusion:</i></b> These results support the idea that sialendoscopy offers symptomatic benefit for patients with chronic sialadenitis due to Sjogren’s or RAI.
