ABSTRACT This text reviews the normal ultrasound (US) anatomy of the salivary glands along with tumoral, lithiasic, and inflammatory pathologies. For salivary gland tumors, US does have limitations (failure to visualize the entire parotid gland, relations with the nerve plexus, in-depth spread of large tumors, false-negative errors of malignancy for small encapsulated tumors). However, US is a simple technique allowing correct identification of the benign nature of a lesion in over 80% of the cases. For lesions under 3 cm in diameter, US is generally the only imaging technique used; for larger lesions, CT or MR is required. Sialolithiasis and inflammatory diseases are being documented by US more and more and the indications for sialography have strongly decreased.

    ABSTRACT: It seems that the choice of the treatment modalities for parotid gland tumors frequently depends on personal experience more than on evidence-based criteria. A nationwide survey was conducted to obtain an overview of current practice in German ENT hospitals. A standardised questionnaire comprising 19 questions on the treatment and diagnostic methods for parotid gland tumors was sent to all ENT hospitals in Germany. The overall return rate of the questionnaires was 128 of 170 (75%). The results confirmed highly variable strategies for the treatment of parotid gland tumors in Germany. On the basis of our survey and the upcoming establishment of a German database for salivary gland cancer in Erlangen, Germany, we hope to be able to clarify controversial topics on the treatment of parotid gland tumors in the near future.

    ABSTRACT: 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.

    ABSTRACT: Salivary mucocele is one of the causes of submandibular swelling in dogs and is due to a collection of mucoid saliva that has leaked from a damaged salivary gland. The purpose of this case series report was to describe the clinical and ultrasonographic characteristics of confirmed salivary mucoceles in 13 dogs admitted to the Faculty of Veterinary Medicine at Cairo University. The final diagnosis of salivary mucocele was based on aspirate cytology for all dogs and additional surgical excision for seven dogs. For dogs admitted from 2 weeks to 1 month from the onset of clinical signs, the cervical mucocele appeared as a round echogenic structure with a large volume of central anechoic content. The wall was a clearly identified hyperechoic structure surrounding the gland. For dogs admitted between 1 to 2 months from the onset of clinical signs, the volume of anechoic material appeared less than that seen in the acute cases. The overall appearance of the salivary mucocele was heterogenous. For dogs admitted after 2 months from the onset of clinical signs, the salivary mucocele appeared grainy or mottled, with a heterogenous appearance and a further decrease in anechoic content. For one dog that presented after 3 months from the onset of clinical signs, the salivary mucocele was hard on palpation and appeared hyperechoic with distal acoustic shadowing. Findings from this study indicated that ultrasonographic characteristics of salivary mucoceles in dogs vary depending on the chronological stage of the disease.
