Endoscopic mechanical retrieval of sialoliths

Objective. We sought to assess the efficacy of sialoendoscopic mechanical retrieval techniques for the treatment of obstructive salivary gland disease. This study documents the authors' long-term experience with mechanical retrieval techniques, the long-term results of the procedures, the technical issues, the techniques that have been used, and the advantages and limitations of these modalities. Study design. Mechanical endoscopic techniques were used in a large referral center from 1993 to 2001 to treat 217 salivary glands for salivary gland sialolithiasis. Results. We found that 189 of the 217 glands with salivary gland sialolithiasis became completely symptom- and stone-free, both endoscopically and by radiographs (overall success rate, 87%). In the submandibular gland group specifically, the success rate was higher, 89%. In the parotid group, it was 83%. Follow-up was continued for 40 months after treatment. No severe complications were noted. The endoscope used was the third-generation Sialoendoscope. Conclusion. The endoscopic mechanical retrieval of sialoliths is both safe and efficacious. This is an excellent method for the complete and certain removal of sialoliths, with minimal damage to the surrounding tissue.
