Fact Explanation
Pain over the gland Parotid and the submandibular glands are the commonly involved salivary glands. Patients complain of pain over the affected gland. When the patient eats the swelling becomes more prominent and the pain also exacerbates. Pain over the gland

Unpleasant taste Discharged pus from the infected glands gives the unpleasant taste. Unpleasant taste

Poor oral hygiene Poor oral hygiene is a predisposing factor for the development of infectious sialadenitis. Common organisms include Streptococcus aureus, Streptococcus viridans, Pseudomonas aeruginosa, Escherichia coli and Moraxella catarrhalis. Poor oral hygiene

Use of radio-contrast material Patients can develop "iodide mumps", iodine induced sialadenitis as a side effect of contrast use. Patients who have underwent procedures which use the radiocontrast materials recently are at risk of developing sialadenitis. Use of radio-contrast material

History of radiotherapy Radiation sialadenitis can occur as a consequence of fibrosis of the gland secondary to radiotherapy to head and neck area. History of radiotherapy
Radiation sialadenitis can occur as a consequence of fibrosis of the gland secondary to radiotherapy to head and neck area.
Risk factors A history of recent dental work should be looked for in the history as this can lead to development of sialadenitis. Presence of autoimmune diseases like Sjogren's syndrome, rheumatoid arthritis, ankylosing spondylitis also increases the risk of sialadenitis. Elderly patients are at high risk because of poor fluid intake and starvation. Risk factors

Clinicals - Examination

Fact Explanation
Febrile Some affected patients are febrile. Febrile
Some affected patients are febrile.
Swelling of the gland Affected gland is swollen, and the overlying skin is erythematous. In parotitis the parotid gland swelling is visible over the angle of the mandible. Swelling of the deep lobe of the parotid gland can be palpated as a diffuse firm swelling over the soft palate and tonsils. Sialadenitis of the submandibular gland causes swelling over the floor of the mouth. Diffuse firm swelling can be palpated bimanually. Swelling of the gland

Sialadenitis of the submandibular gland causes swelling over the floor of the mouth. Diffuse firm swelling can be palpated bimanually.
Tenderness of the gland Salivary glands are tender to palpation in sialadenitis. Superficial lobe of the parotid gland is tender to palpation over the angle of the jaw. Intraoral examination will reveal tenderness over the soft palate if the deep lobe of the parotid gland is involved. Submandibular gland is tender on bimanual palpation. Tenderness of the gland

Discharge Purulent discharge can be seen at the site of opening of the ducts, especially the Wharton’s duct of the salivary gland. The opening of the Wharton's duct lies on the anterior floor of the mouth at the sublingual papilla. Discharge

Signs suggestive of autoimmune diseases Patients with Sjogren's syndrome have dry eyes and dry mucous membranes. Rheumatoid nodules, joint deformities like swan neck deformity, symmetrical swelling of the small joints of the hand and "Z thumb" deformity are suggestive of rheumatoid arthritis.

Investigations - Diagnosis

Fact Explanation
Ultrasound scan Since the salivary glands lie superficially ultrasound scan is considered a sensitive investigation to diagnose sialadenitis. When compared to CT scan ultrasound scan is non-invasive and does not carry the risk of radiation exposure.
Color Doppler ultrasound scan is useful in detecting increased vasculature of the gland in sialadenitis.
Ultrasound scan can also detect the presence of calculi.
Anatomical abnormalities of the ducts can also be detected by the ultrasound scan.

Fine needle aspiration cytology Focal lymphocytic sialadenitis is the characteristic histological pattern of Sjogren's syndrome. Fine needle aspiration cytology

X-ray sialography X-ray sialography is contraindicated in suspected sialadenitis because it may aggravate the inflammation. X-ray sialography

Management - Supportive

Fact Explanation
Health education If poor oral hygiene is considered the possible etiological factor for the development of sialadenitis, patients should be advised to maintain good oral hygiene to prevent further episodes. Health education

Rehydration Elderly patients are sometimes dehydrated due to poor oral intake. If the patient is unable to take oral fluids administration of intravenous fluid is necessary. Rehydration

Management - Specific

Fact Explanation
Conservative managment Patients with acute viral diadadenitis and most of the patients with suppurative sialadenitis recover uneventfully. Conservative managment
Patients with acute viral diadadenitis and most of the patients with suppurative sialadenitis recover uneventfully.
Antibiotics Antibiotics are recommended for the treatment of suppurative sialadenitis. Antistreptococcal antibiotics (penicillin, erythromycin, amoxicillin, cephalexin) can be administered empirically as Streptococcus is one of the commonest causative bacteria. Antibiotics

Sialadenectomy For patients with failed conservative and medical management surgical removal of the gland is practiced. Sialadenectomy

Surgical drainage If suppurative sialadenitis has developed in to an abscess, surgical drainage is necessary. Abscess is drained via a large bore needle under general anesthesia. Surgical drainage
