Sialolithiasis in the sublingual gland

Sialendoscopy for Sublingual Gland Sialolithiasis

Objectives:

To present a unique series of sublingual gland sialolithiasis treated with sialendoscopy.

Methods:

A retrospective chart review of patients at a single tertiary care academic center undergoing sialendoscopy.

Results:

We present a series of 4 patients who presented with 1 episode each of sialadenitis without preceding postprandial symptoms. In each case, sialendoscopy identified the calculi embedded within the sublingual duct of Bartholin at its emptying point into Wharton’s duct. The large size of the stones did not permit endoscopic removal, and transoral excision was performed via a floor of mouth incision. All patients recovered well with resolution of preoperative symptoms.

Conclusions:

Sublingual gland sialolithiasis has a distinct presentation that is not associated with obstructive symptoms and may be successfully treated with a combined endoscopic and transoral approach. Sialendoscopy allows identification of the location of the sialolith to guide removal and helps identify stone fragments and additional stones remaining after sialolithotomy. Transoral resection of the sublingual gland in this scenario facilitates stone removal and may minimize long-term chance of ranula formation.

Association of serum electrolytes and smoking with salivary gland stone formation

To further define potential factors that may contribute to stone formation in salivary glands (sialolithiasis), a retrospective chart review was performed of patients diagnosed with sialolithiasis between March 1, 1998 and February 29, 2012. Information on salivary gland stone number, location and size, medical history, medications, and serum electrolyte levels were collected. Associations between electrolyte levels and stone characteristics (such as stone number and size) were examined. Fifty-nine patients were identified; their median age was 58 years (range 25-89 years) and most were male (95%). Salivary stones were most commonly located in the submandibular glands (83%). Thirty-five patients (59%) had a smoking history, with 16 (27%) reported as current smokers. There was a significant association between current smoker status and stone size (mean largest stone size 12.4±8.8mm vs. 7.5±4.8mm in current smokers vs. non-smokers; P=0.03). Serum sodium levels (r=0.32, P=0.014) and serum potassium levels (r=0.31, P=0.017) showed significant positive correlations with stone size. While the aetiology of sialolithiasis remains unclear, smoking (which can contribute to reduced saliva flow) and higher serum sodium levels (which can reflect volume depletion) are associated with larger salivary stones.

Multiple sialolithiasis in sublingual gland causing dysphagia

Background:

Sialolithiasis is a common disease of the major salivary glands, but it is rarely seen in the sublingual gland. Patients commonly experience pain and/or swelling, but dysphagia is presented in extended lesions.

Case Report:

In this report we present a 67-year-old woman who had 268 sialoliths in the sublingual gland, forming a huge mass and causing dysphagia. The diameter of the largest sialolith was approximately 4 mm. The diagnosis of sialolithiasis was confirmed pathologically.

Conclusions:

Multiple sublingual gland sialoliths are considered rare; they may cause symptoms like dysphagia and speech difficulty. To our knowledge our patient had more sialoliths in a sublingual gland than any previous reports in the literature.

Long-term evaluation of extracorporeal shock wave lithotripsy in the treatment of salivary stones

Extracorporeal shock wave lithotripsy is a rather new therapeutical method in the treatment of sialolithiasis. The objective was to evaluate retrospectively the results of the extracorporeal shock wave lithotripsy therapy performed with a Minilith SL 1 lithotripter on 167 out-patients with symptomatic stones (average size 5.94 mm) of the salivary glands over an observation period of seven years. A successful treatment with total stone disintegration was achieved in 51 (31 per cent) patients. In 92 (55 per cent) patients treatment was partially successful, with disappearance of the symptoms but a sonographically still identifiable stone. Treatment failure occurred in 24 (14 per cent) patients who then underwent surgery. The mean follow-up period was 35.6 months (minimum three, maximum 83), after which 83.2 per cent of the initially successfully treated patients were still free of symptoms.Therefore, extracorporeal shock wave lithotripsy, as a non-invasive treatment alternative with few side effects, is an efficient technique for the therapy of sialolithiasis in selected patients.

Unusual Asymptomatic Giant Sialolith of the Submandibular Gland

This report presents an unusual case of asymptomatic sialolith of the submandibular gland. A 61-year-old man was referred to our department for multiple extractions. An ortopantomographic exam revealed the existence of a large radiopacity in the right premolar mandibular region. The patient was completely asymptomatic and no episodes of pain and swelling had occurred in the previous years. Ultrasonography and clinical examination confirmed the diagnosis of sialolithiasis of the submandibular duct. The calculus was removed trans-orally in local anaesthesia. The sialolith measured 22 mm and it was mainly constituted by phosphate, calcium and smaller amounts of magnesium. The bacteriological exam revealed the presence of Streptococcus Mitis, Streptococcus Salivarius and non-pathogenic Neisserie. Postoperative course was uneventful. Even a sialolith of significant dimensions may not be symptomatic. Nevertheless, the likelihood of future complications may constitute an indication for surgical removal of abnormal asymptomatic sialoliths.
