Management of Excessive Salivation After Submandibular Duct Surgery
Initial Assessment and Airway Management
- Excessive salivation after submandibular duct surgery requires prompt evaluation as it may lead to potentially life-threatening airway compromise 1
- Maintain a very low threshold for reintubation if acute sialadenitis with excessive salivation is suspected, as 13 of 15 patients in reported cases required deferred extubation, early reintubation, or emergent tracheostomy 2
- Monitor for signs of submandibular swelling, which typically presents within 4 hours following surgical closure 3
Medical Management Options
- Apply warm compresses to the affected area to promote salivary gland excretion 2
- Perform gentle massage of the salivary gland (use with caution in elderly patients or those with suspected carotid stenosis) 2
- Administer sialagogues to stimulate salivary flow and reduce stasis 2
- Provide aggressive intravenous hydration, particularly important for patients with compromised oral intake 2
Monitoring and Complications
- Watch for potential neurologic complications associated with excessive salivation and inflammation, including brachial plexopathy, facial nerve palsy, and Horner syndrome 1
- Monitor for signs of bacterial superinfection, though this appears uncommon in post-surgical sialadenitis 2
- Corticosteroids may be considered for significant airway swelling (used in 47.4% of cases in systematic review) 2
Long-term Considerations
- Most patients with post-surgical sialadenitis achieve complete or near-complete recovery when properly managed 2
