Salivary gland stone removaL
When the diameter of the stone is 5mm or less, it can be removed purely by an endoscopic technique, particularly when the stone is located above the muscles that comprise the floor of the mouth. The four common techniques used to remove the salivary gland stones are:
The grasping technique
Using a small wire basket retrieval system
Mechanical Fragmentation
Laser fragmentation
When the diameter is larger than 5 mm, a twofold (endoscopic assisted) approach can be utilized. The endoscope is introduced and the stone localized, and then dissected and removed in an intraoral approach. After a sialolith is removed from an affected gland, a sialastic stent is inserted into the duct for two to four weeks for the duration of the healing process of the oral region and until normal function of the gland is restored. This prevents scar formation which can develop overlying the ductal opening into the mouth.
