What is the treatment for sialolithiasis?

Treatment of Sialolithiasis

The treatment of sialolithiasis should follow a stepwise approach, beginning with conservative measures for smaller stones and progressing to more invasive procedures for larger stones or those causing significant symptoms. Conservative management includes hydration, sialagogues, warm compresses, and massage, while surgical options range from minimally invasive techniques to gland removal depending on stone size and location 1, 2.

Initial Conservative Management

• Hydration and sialagogues: Increased fluid intake and use of substances that stimulate salivary flow (such as lemon drops or vitamin C) can help flush out smaller stones 2
• Warm compresses and massage: Application of warm compresses to the affected area and gentle massage of the gland toward the duct opening may help smaller stones move through the duct 3
• Analgesics and antibiotics: Oral analgesics for pain management and antibiotics if infection is present 3
• Anticholinergic medications: For patients with excessive salivation (sialorrhea) that may exacerbate symptoms, anticholinergic medications can be used as first-line therapy 4

Minimally Invasive Procedures

• Duct dilation and stone extraction: For stones located in the anterior portion of the duct that are accessible, dilation of the duct opening followed by extraction may be performed 2, 5
• Sialendoscopy: Endoscopic visualization and removal of stones using specialized instruments, particularly effective for smaller stones in accessible locations 3
• Lithotripsy: Fragmentation of larger stones using shock waves, allowing the fragments to pass naturally or be removed more easily 2

Surgical Management

• Intraoral surgical removal: For stones in the anterior or middle portion of the submandibular or parotid duct that are accessible through an intraoral approach 5
• Sialadenectomy (gland removal): Reserved for cases with:
  • Large stones (>10mm) located deep in the gland 1
  • Recurrent stone formation despite conservative measures 2
  • Chronic sialadenitis with glandular atrophy 3
  • Stones causing significant obstruction and symptoms that cannot be managed by other means 1, 2

Treatment Based on Stone Location

Submandibular Gland (80-90% of cases)

• Most common location due to the curved course of the duct and more mucous secretions 1
• Anterior duct stones: Intraoral surgical approach with direct incision over the stone 5
• Posterior duct/intraglandular stones: May require complete gland removal 1

Parotid Gland

• Conservative management is preferred initially
• Surgical approaches must consider the facial nerve
• Sialendoscopy is particularly valuable in this location 3

Complications and Follow-up

• Recurrence prevention: Increased hydration and oral hygiene after successful treatment 2
• Monitoring for complications: Watch for signs of infection, duct stricture, or recurrent stone formation 3
• Glandular function assessment: Evaluate salivary flow after treatment to ensure restoration of function 5

Special Considerations

• Large stones (>10mm): These unusual cases often require surgical removal as they rarely pass spontaneously 1, 5
• Multiple stones: May indicate a systemic issue or chronic inflammation requiring more aggressive management 3
• Bilateral involvement: Consider systemic causes and manage accordingly 6

The choice of treatment should be guided by stone size, location, number of stones, severity of symptoms, and the patient's overall health status. Early intervention is recommended to prevent chronic sialadenitis and permanent glandular damage 3.
