Retrograde probing technique to enter Wharton's duct at sialendoscopy

Objective: The retrograde probing technique defined here, that is used where the Wharton papilla cannot be isolated and the standart procedure be applied, has minimal impact on normal anatomy. The efficiency and the safety of this technique is discussed in this study. Methods: The study was conducted in patients who had been diagnosed as stone in the submandibular gland. The method we call "retrograde probing" was applied to 11 patients in whom the Wharton's duct papilla could not be isolated. Results: In all cases in this study, it was possible to enter the canal by this method. The insertion of 1.6 mm all-in-one endoscope; as a result, can be evaluated as success. The study did not evaluate stone related interventions after entering the canal. Conclusion: Based on the results, retrograde probing is determined as a safe method in cases where Wharton canal entry cannot be isolated.
