Sialendoscopy is used in the diagnosis and treatment of various symptoms relating to the salivary gland, e.g. chronic swelling or obstruction and inflammation of the salivary duct. Small intraductal stones can be removed with various instruments during sialendoscopy, whereas larger ones can be fragmented with extracorporeal shockwave lithotripsy or laser. However, 5-10% of the patients with parotid stones cannot be treated with these methods. In patients with large impacted stones or stones in a hilus area, a combined endoscopic and transcutaneous technique can be employed. The stone is approached endoscopically, a skin flap is raised over or a small incision is made through the illuminated area, and the stone is removed by an external route with minimal morbidity. This retrospective study analysed the cases of 8 patients treated using the combined technique, 6 of whom became symptom free. Superficial parotidectomy was performed in 1 patient. No complications were observed, and ductal stents were not used. The average diameter of the stones was 7.6 mm (range 7.0-10.2). The combined technique is recommended for the removal of large and impacted intraductal stones in the parotid gland. No major complications have been reported.
