Surgical correction of recurrent stenosed submandibular duct orifice.

Ten patients complaining of recurrent stone formation in submandibular stenosed duct orifice were diagnosed and evaluated. Surgical technique for removal of the stones and widening of the orifice to heal by secondary intention was discussed. Irrigation of the duct and wound with 5% diluted hydrogen peroxide was done to remove all desquamated epithelial cells and microliths to prevent narrowing the lumen of the duct. One year post operative follow up revealed no recurrence of stone formation in the submandibular duct and normal salivary flow for all patients.
