Ultrasound in salivary gland disease.
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: To determine clinical findings, cytologic and histologic characteristics of salivary glands, and response to treatment with phenobarbital in dogs with clinical signs typical of sialadenosis. Prospective study. 13 dogs with enlarged salivary glands. Data were collected from dogs with clinical signs attributable to enlarged salivary glands. Salivary gland biopsy and cytologic specimens were examined. Dogs were treated with phenobarbital and monitored for response to treatment. Clinical signs commonly associated with sialadenosis included retching and gulping. Substantial cellular changes were not detected by histologic or cytologic examination of enlarged salivary glands. Response to treatment with phenobarbital was rapid, although most dogs required continuous treatment to prevent recurrence of clinical signs. Sialadenosis is a condition of unknown cause that may have been underdiagnosed in dogs. Criteria for diagnosis include typical clinical signs, enlarged salivary glands, and lack of substantial microscopic lesions. Response to treatment with phenobarbital is rapid.Journal of the American Veterinary Medical Association 03/2000; 216(6):872-4. DOI:10.2460/javma.2000.216.872 · 1.67 Impact Factor

ABSTRACT: We sought to compare the diagnostic utility of magnetic resonance sialography (MRS) and digital subtraction sialography (DSS) in patients with suspected sialolithiasis or sialadenitis. Sixteen consecutive patients (4 female and 12 male, mean age 51 ± 16 years) with suspected sialolithiasis or sialadenitis underwent DSS by a standard technique and MRS. MRS was obtained with a T2-weighted single-shot TSE sequence (TR/TE 2800/1100 msec, acquisition time 7 seconds) using a quadrature head (n = 16) and a surface coil (n = 8). Nineteen symptomatic glands were investigated with DSS: eight submandibular glands in 6 patients (two bilateral) and unilateral parotid glands in 11 patients. MRS was always carried out to visualize gland ducts bilaterally. The ductal system was visualized in all glands examined by MRS. DSS depicted the ductal system in all 11 parotid glands, but only 4 of the 8 submandibular glands (50%). Sialolithiasis was diagnosed in three cases (one parotid, two submandibular glands) by MRS and in two cases by DSS. DSS demonstrated tertiary branching ducts and MRS secondary branching ducts. MRS is able to visualize the ductal system of the parotid and submandibular gland noninvasively and is thus not dependent on successful cannulation of the orifice of the ductal system. Our preliminary data indicate that MRS is useful for diagnosing sialolithiasis. MRS allows diagnosis of sialadenitic changes, but DSS achieves a better diagnostic performance due to higher spatial resolution. J. Magn. Reson.

ABSTRACT: Die Strategien zur Diagnostik und Behandlung von Parotistumoren scheinen in den deutschen HNO-Kliniken teilweise äußerst unterschiedlich zu sein. Ziel dieser Arbeit war es, mittels einer deutschlandweiten Umfrage einen Überblick über den derzeitigen Stand zu gewinnen.Allen deutschen HNO-Kliniken wurde postalisch ein standardisierter Fragebogen mit 19 Fragen zur Diagnostik und Behandlung von Parotistumoren zugesandt.Die Gesamtrücksendequote betrug 128 von 170 versandten Fragebögen (75%). Es bestätigte sich die Annahme, dass Parotistumoren in deutschen HNO-Kliniken sehr uneinheitlich behandelt werden.Auf der Grundlage der von uns erhobenen Daten und der ausstehenden Etablierung des klinischen Registers für Speicheldrüsenmalignome in Erlangen besteht Hoffnung, dass wichtige Fragen zur Behandlung von Speicheldrüsentumoren in naher Zukunft beantwortet werden können.HNO 11/2006; 54(11). · 0.54 Impact Factor
