Abstract
Piezoelectric lithotripsy was undertaken on 19 patients with salivary stones, with none of these patients requiring anesthesia, analgetics, or sedatives. All salivary stones were totally fragmented during first lithotripsy. Four months after treatment with extracorporeal shock waves, all patients were free of symptoms and, in 11 of the patients, no calculi could be found sonographically. The piezoelectric lithotripsy of salivary stones caused no serious side effects which could be proven by clinical, biochemical, sonographic, and magnetic resonance imaging (MRI) examinations. Extracorporeal piezoelectric lithotripsy is a new and promising nonsurgical therapy for selected cases of sialolithiasis of the parotid and submandibular glands.
