Sialendoscopy for non-stone disorders: The current evidence.

Abstract

ObjectiveReview the current literature on the use of sialendoscopy in the treatment of non‐stone disorders of the major salivary glands.Data SourcesEligible articles that reported on the use of sialendoscopy in the treatment of non‐stone disorders were identified using MEDLINE, Embase, and Google Scholar through May 2016. The search used key words sialendoscopy, salivary endoscopy, salivary scope, salivary duct stenosis, salivary duct stricture, Sjogren's disease, radioiodine sialadenitis, salivary duct obstruction, sialadenitis, chronic sialadenitis, juvenile recurrent parotitis, parotitis, and radiation sialadenitis.Review MethodsFull‐length prospective and retrospective original articles; systemic reviews; and meta‐analysis, including adults and children with adequate data for evaluating the sialendoscopy for non‐stone disorders, were included. Individual case reports were excluded.ResultsThere is an increasing trend for the use of sialendoscopy for salivary obstruction caused by a wide variety of non‐stone disorders worldwide. The studies of sialendoscopy for non‐stone disorders are often retrospective, of smaller sample size, and more subjective in measurement of patient outcome. The most common indications currently for the procedure are scars, juvenile recurrent parotitis, radioiodine sialadenitis, and Sjögren syndrome, respectively.ConclusionAlthough the initial evidence for the use of sialendoscopy for non‐stone disorders is not as established as that for stones, it remains a promising gland‐preserving tool in the management of non‐stone disorders of major salivary glands.
