Chronic sialorrhea
Specialty: Otolaryngology.
Why it occurs
- Neuromuscular dysfunction or swallowing problems in patients with cerebral palsy, Parkinson's disease or amyotrophic lateral sclerosis
- Side effect of psychotropic drugs, especially clozapine or cholinergic agonists
- Severe gastroesophageal reflux disease that triggers the esophagosalivary reflex
- Stomatitis or chronic infections of the oral mucosa that stimulate reflex hypersecretion
Initial workup
Multidisciplinary evaluation of swallowing with videofluoroscopy or nasofibrolaryngoscopy of swallowing (FEES), monitoring of quantitative salivary secretion, and detailed review of the patient's active medication list.
red flags
Rapidly progressive dysphagia associated with progressive weight loss, recurrent saliva aspirations with documented chemical pneumonia, absolute inability to manage secretions with imminent risk of asphyxiation, or progressive generalized bulbar muscle weakness.
Standard management
- Oral anticholinergics such as scopolamine hydrobromide — in extended-release transdermal patches applied to the retroauricular region every 72 hours) or glycopyrrolate (1-2 mg orally every 8-12 hours, closely monitoring side effects such as urinary retention, constipation, and blurred vision
- 1% atropine eye drops administered sublingually — 1-2 drops every 8-12 hours
- Infiltration of botulinum toxin type A in parotid and submandibular glands under ultrasound control.
