Sialendoscopy and sialendoscopically-assisted operations in the treatment of lithiasis of the submandibular and parotid glands: our experience of 239 cases.

We present the results of treatment of sialolithiasis of the submandibular and parotid glands using sialendoscopy and sialendoscopy-assisted surgery. Between 2009-2013, 397 consecutive patients (mean (range) age 48 (18-76) years) were treated for obstructive diseases of the major salivary glands (sialolithiasis n=239, 175 submandibular and 64 parotid). In a total of 175 patients with 191 stones in the submandibular gland treated by endoscopic retrieval or surgical release, 149 patients (85%) were rendered free of stones (by sialendoscopy alone n=82, and sialendoscopy with operation n=67) Twenty patients (11%) had residual stones and 6 patients (4%) required excisionof the gland. Sixty-four patients had 71 stones removed from the parotid gland by endoscopic retrieval or surgical release and 43 (67%) were free of stones (by sialendoscopy alone n=25, and sialendoscopy with operation n=18). Twenty patients (31%) had residual stones and one (2%) required removal of the gland. In the group of patients whose stones were removed endoscopically, the effectiveness of sialendoscopy was 87% and 85%, respectively. We confirm that sialendoscopy and sialendoscopy-assisted removal is the current treatment of choice for stones in the submandibular and parotid glands. The indications for excision of the gland are becoming less common as first-line treatment, although it is still indispensable in some cases.

Summary Objectives The introduction of minimally invasive surgical procedures has significantly reduced the rate of major salivary gland removal due to sialolithiasis. The aim of the analysis was to assess the effectiveness of sialoendoscopy and combined approach in most difficult cases. Material and Methods prospective study, tertiary university centre (Department of Otorhinolaryngology, Head and Neck Surgery, Poznan), between XII 2008 and V 2012, 207 sialendoscopies were performed in 197 patients. In this number 158 patients had obstructive pathology of salivary glands, 95 confirmed gland or duct sialolithiasis: parotid – 31 and submandibular – 64. Results In the group of submandibular lithaiasis in 40 cases (62.5%) stones were removed endoscopically. Double approach (sialendoscopy and incision of mucosa of the floor of the mouth with removal of the stone was perfomed in 21 cases (32.8%). Only in 3 cases removal of submandibular gland was necessary. In the group of parotid sialolithiasis in 17 cases (54%) endoscopy was the definite treatment, in 9 litothrypsy (ESWL) were necessary and in 5 combined approach. This five patients who failed SE were treated by combined transcutaneous (open surgery) and endoscopic procedure. We observed no incidence of salivary fistula after the incision of the duct; there was also no stenosis of the natural ostium due to the insertion of a stent. Conclusions Sialoendoscopy is method of choice with high rate of success and gland preservation in small and moderate stones. The combined approach is indicated for large stones, complications and where there is a contraindication to established minimally invasive procedures.
