Background and objectives: Sialoendoscopy is a minimally invasive technique that allows exploration of the salivary ducts and the treatment of inflammatory sialadenitis, sialolithiasis and major salivary glands ductal stenosis. The main objectives are to perform a diagnostic examination of the duct, elimination of possible stenosis or obstructions and to improve glandular function.
Materials and methods: We performed a retrospective analysis of the sialoendoscopies done in our department between 2010 and 2012 and give descriptive epidemiological data and results. The treatment protocol and surgical technique are described.
Results: A total of 45 patients have been treated with this technique. The indications include Wharton and Stenon duct explorations. We review the success of the procedure and its indications, confirmation of the initial diagnosis after the procedure and posterior relapse and adenectomies.
Conclusions: Sialoendoscopy is a technical-dependent operation that requires a learning curve and it is especially suitable for endoscopic removal of stones smaller than 4 mm in the submandibular gland and 3 mm in the parotid gland. It is also important in the diagnosis and treatment of chronic sialadenitis and intraductal pathology. Given its low morbidity and good results it allows treating more patients and reduces the number of adenectomies.
