Sialorrhea

Sialorrhea, also known as hypersalivation or drooling, is the unintentional pooling and spillage of saliva beyond the oral cavity or into the posterior pharynx Although common and physiologically benign in infants, it is considered abnormal after approximately four years of age and most frequently affects pediatric and adult populations with neuromuscular or neurodegenerative disorders, such as cerebral palsy, Parkinson’s disease, and amyotrophic lateral sclerosis

Sialorrhea, also known as hypersalivation or drooling, is the unintentional pooling and spillage of saliva beyond the oral cavity or into the posterior pharynx If left unmanaged, persistent sialorrhea can cause perioral skin breakdown, impaired speech, dehydration, social stigmatization, and chronic aspiration leading to recurrent respiratory infections

Pathophysiologically, the condition is rarely caused by absolute salivary hypersecretion; instead, it typically stems from impaired swallowing mechanisms, deficient neuromuscular control of the tongue and facial musculature, sensory deficits, or postural abnormalities If left unmanaged, persistent sialorrhea can cause perioral skin breakdown, impaired speech, dehydration, social stigmatization, and chronic aspiration leading to recurrent respiratory infections
