목적: This study was performed to know the clinical features and treatment outcome of salivary duct stenosis. 방법:We retrospectively enrolled 86 patients with salivary duct stenosis between November 2013 and January 2015. Conventional sialography and magnetic resonance sialography were used to diagnose salivary duct stenosis. Clinicopathologic data and sialographic findings were assessed and prognostic factors related to treatment outcome were identified. 결과:Eighty-six patients (29 women, 57 men) with a mean age of 42.9 years (7~66) received conservative treatment preferentially. Symptoms arising from parotid gland were seen in 107 (85%) of glands, whereas submandibular gland in 19 (15%). Thirty-six patients (42%) presented symptoms in bilateral glands. The causes of stenosis remained unclear in most cases, however, radioiodine administration, autoimmune disease, trauma and chronic sialadenitis were considered to be the cause of stenosis. Fifty-seven patients (66%) had symptomatic improvement, whereas 29 patients (34%) were unresponsive to conservative management. Nineteen patients who had not improved symptoms underwent sialendoscopy. Associated procedures were done including steroid infusion, bougienage and ductal stent insertion, transoral ductal surgery (end to end ductal anastomosis and/or sialodochoplasty). Nine of eleven patients (82%) who received steroid infusion and/or bougienage and ductal stent insertion had symptomatic improvement. All eight patients who received transoral ductal surgery had symptomatic improvement. Male, symptom duration, severe sialectasis and small glandular volume were prognostic factors preferring surgical treatment rather than conservative management. 결론:Conservative treatment could provide symptom improvement in most patients. Therapeutic sialendoscopy or sialendoscopy-assisted surgical management may be effective procedures for improving symptoms of patients with salivary duct stenosis who are unresponsive to conservative managements.
