Purpose: To describe the technique and examine the value of salivary stone extraction using a minimally invasive, radiologically guided approach as an alternative to salivary gland surgery for the treatment of benign salivary gland obstruction. Methods: Eighty-six cases of sialolithiasis (83 patients) were treated by stone removal using a Dormia basket under local anesthesia and fluoroscopic guidance. Postoperative assessment was made clinically at review, by sialogram and by questionnaire. Results: Of 86 cases of sialolithiasis treated, in 55 (64%) it was possible to remove all stones. In 12 cases (14%) part of a stone or some of a number of calculi were removed and in 19 cases (22%) the procedure failed. The commonest reason for failure was fixation of the stone within the duct. Symptoms at review (range 1-49 months, mean 17 months) were relieved in 55 of 67 (82%) of cases where a stone or portion of stone was removed. Conclusions: Stone removal from the salivary duct system by radiologically guided, minimally invasive approach is a simple procedure with low morbidity and high patient acceptance when appropriate selection criteria are applied. These criteria are considered and recommendations made.
