What is the appropriate treatment for parotitis?

Treatment of Parotitis

The appropriate treatment for parotitis includes antimicrobial therapy targeting Staphylococcus aureus and anaerobic bacteria, combined with supportive care including anti-inflammatory oral rinses, analgesics, and proper hydration. 1, 2

Initial Management Approach

• Begin with supportive care measures to manage symptoms and inflammation:

  • Anti-inflammatory oral rinses or sprays containing benzydamine hydrochloride every 3 hours, particularly before meals 1
  • Warm saline mouthwashes daily to reduce bacterial colonization 1
  • Antiseptic oral rinses twice daily (0.2% chlorhexidine digluconate or 1.5% hydrogen peroxide) 1
  • Adequate hydration to promote salivary flow and prevent worsening 2

• For pain management:

  • Topical anesthetic preparations such as viscous lidocaine 2% for localized pain relief 1
  • Systemic analgesics following the WHO pain ladder for more severe pain 1
  • Mucoprotectant mouthwash three times daily (such as Gelclair) to protect ulcerated surfaces 1
  • White soft paraffin ointment for affected lips 1

Antimicrobial Therapy

• For acute bacterial parotitis, initiate antimicrobial therapy targeting the most common pathogens:

  • First-line options include amoxicillin, doxycycline, or trimethoprim-sulfamethoxazole for mild to moderate cases 3, 2
  • For more severe infections or hospitalized patients, consider parenteral antibiotics with coverage against S. aureus and anaerobic bacteria 2
  • For patients with recent antibiotic use or at risk for resistant organisms, broader coverage may be necessary 3

• Special considerations:

  • For suspected candidal infection, add nystatin oral suspension or miconazole oral gel 1
  • For patients with gram-negative infections (more common in hospitalized patients), ensure appropriate coverage 2

Management Based on Severity and Type

Acute Bacterial Parotitis

• Mild cases: Oral antibiotics (amoxicillin, doxycycline, or trimethoprim-sulfamethoxazole) plus supportive care 3, 2
• Severe cases: Parenteral antibiotics and possible surgical drainage if abscess formation occurs 2
• Duration of therapy typically 7-10 days, with reassessment after 72 hours 3

Chronic or Recurrent Parotitis

• Initial management with antibiotics during acute flares 4
• Consider diagnostic sialography or sialoendoscopy to identify underlying causes like strictures or stones 5, 6
• For stones or strictures, interventional procedures may be beneficial:
  • Removal of stones with Dormia basket 5
  • Dilation of strictures with balloon catheter 5
• For persistent cases not responding to conservative management, surgical options may be considered, though these carry significant risks 6

Pitfalls and Caveats

• Failure to maintain adequate hydration can worsen symptoms and delay recovery 2
• Inadequate antimicrobial coverage may lead to treatment failure; reassess if no improvement after 72 hours 3
• Overlooking underlying causes (stones, strictures) in recurrent cases can lead to continued symptoms 5, 6
• Surgical intervention carries risks including facial nerve damage and should be reserved for cases failing conservative management 6
• Fungal infections may complicate bacterial parotitis and require specific antifungal treatment 1

Follow-up and Prevention

• Maintain good oral hygiene to prevent recurrence 2
• Ensure adequate hydration, particularly in elderly or debilitated patients 2
• Early and appropriate treatment of oropharyngeal infections may reduce the occurrence of suppurative parotitis 2
• For recurrent cases, consider referral to specialist for evaluation of underlying causes 6
