Sialendoscopy-assisted intraoral incision approach for the treatment of posterior Wharton's duct stones: our experience and outcomes.

INTRODUCTION

Sialoliths can be removed by sialendoscopy in some cases. But sometimes it fails if the stone is located in the proximal or hilum of Wharton's duct.

AIM

To evaluate the clinical efficacy of the sialendoscopy-assisted intraoral incision approach to remove large stones located in the proximal or hilum of Wharton's duct, when sialendoscopy alone fails.

MATERIAL AND METHODS

Twenty patients with large stones located in the proximal or hilum of Wharton's duct were included in our study. We used a sialendoscopy-assisted intraoral incision approach to remove large stones located in the proximal or hilum of Wharton's duct when endoscopy failed. The complications and treatment effect were observed.

RESULTS

The stones were removed successfully in this way in all patients. Two cases had tongue numbness after the operation, and recovered 3 months later without additional intervention. No swelling or pain appeared during the 3-month to 1-year follow-up. Saliva could be observed from the orifice in 15 patients, with little or none in 5 patients.

CONCLUSIONS

The sialendoscopy-assisted intraoral incision approach to remove large stones located in the proximal or hilum of Wharton's duct is effective and safe.
