In this video, the left submandibular duct was blocked by a small stone (calculi) which had caused infection of the gland with pus formation.  Imaging study showed no evidence of calculi within the gland itself and the implicated stone was located just before the natural duct opening.  Local anaesthesia infiltration was given followed by incision using radiofrequency device along the long axis of the duct where the stone felt (the natural duct opening was spared).  Pus gush out as the duct lumen reached.  Careful suctioning and manipulation enable the small stone to be retrieved (attached to suction device end).  The opening was left unsutured as it can healed readily.  An antibiotic course and mouth rinse were prescribed.
