From the Research

Bacterial sialadenitis is best managed with a combination of supportive care, antibiotics, and sometimes surgical intervention, with empiric antibiotic therapy started promptly with amoxicillin-clavulanate or clindamycin, as recommended by the most recent study 1. The initial diagnosis relies on clinical presentation of painful swelling of the affected salivary gland, purulent discharge from the duct, and systemic symptoms like fever.

  • Key points to consider in the diagnosis and management of bacterial sialadenitis include:
    • Clinical presentation and history
    • Physical examination
    • Imaging studies, such as ultrasound or CT scans, to evaluate for abscess formation or other complications
    • Laboratory tests, such as bacteriological sampling, to guide antibiotic therapy
  • Supportive measures are crucial in the management of bacterial sialadenitis, including:
    • Adequate hydration
    • Warm compresses to the affected area
    • Salivary massage
    • Sialogogues, such as lemon drops, to stimulate saliva flow
    • Pain management with NSAIDs or acetaminophen
  • The most recent study 2 recommends probabilistic antibiotic therapy for 10 days, with the most frequent germ being Staphylococcus aureus, and emphasizes the importance of rehydration, especially in elderly patients. The pathophysiology of bacterial sialadenitis typically involves ductal obstruction, often from stones or strictures, leading to stasis of saliva, which creates an environment for bacterial overgrowth, most commonly ascending from the oral cavity, as discussed in 3 and 4.
  • Chronic or recurrent cases may require further evaluation and management, including:
    • Sialendoscopy to remove stones or dilate strictures
    • Surgical excision of the affected gland in severe cases
  • It is essential to practice good oral hygiene and avoid dehydration to prevent recurrence, as highlighted in 5 and 1.
