Open surgical management of sialolithiasis

Sialolithiasis should be considered in the differential diagnosis of any patient with persitent or recurring salivary gland swelling or inflammation. It occurs most frequently in the Wharton duct followed by the Stensen duct, and rarely in the sublingual glands. Sialolithiasis typically presents with pain and swelling of the involved gland and is aggravated by eating. In the acute setting, patients with sialadenitis secondary to calculi are treated conservatively with antibiotics, and stones less than 2 mm may pass spontaneously. Sialendoscopy is now well established as a novel minimally invasive diagnostic and therapeutic modality for salivary gland stones. Sialoendoscopes can also be used in combination with several open surgical approaches to guide the extraction of large calculi. This article highlights the open surgical interventions that are frequently used in sialolithiasis management, when sialoendoscopy is not the most appropriate option, has failed, or is not available. They range from minimally invasive to open techniques. Mastering the anatomy of the salivary ducts and surrounding structures is of exquisite importance. The management of sialolithiasis should aim for gland-sparing procedures before considering gland excision.
