Interventional sialendoscopy in parotidomegaly related to eating disorders

Background: To evaluate the viability and efficacy of sialendoscopy for the management of parotidomegaly related to eating disorders, 6 patients suffering from eating disorders and recurring symptoms of glandular swelling were followed up at the Multidisciplinary Department of Medical-Surgical and Dental Specialties, Oral and Maxillofacial Surgery Unit, AOU University of Campania “Luigi Vanvitelli”. After the detection of the impaired gland through clinical and radiographical analysis, the diagnostic unit was introduced into the duct and was advanced in, reaching the ductal system. Plaques were washed out, any strictures were dilated both by hydrostatic pressure application and steroid solution injection directly in the fibrotic area. Results: Both glands resulted affected in 83% of patients. 11 parotid glands were explored and treated. Strictures were found in 2 glands (33%), sialectasis in 3 glands (50%), strictures and sialectasis together in 1 glands (17%). In 3 parotid glands (50%) Stenon’s duct was affected, in two (33%) only secondary ducts, in 1 (17%) both. We reached symptomatic improvement in 5 patients (83%), reporting the spherical volume of the parotid region and pain reduction. Conclusions: Our results demonstrate that sialendoscopy is a safe and effective therapeutic method to treat EDs salivary symptoms. Treating the underlining psychiatric pathology should be the primary goal in patient care to lower the possible recurrence rate and increase the successful outcome of this technique.
