When saliva becomes a problem: the challenges and palliative care for patients with sialorrhea

Abstract

Sialorrhea, or relative excess of salivary excretion, is a vexing problem for many patients. This symptom is precipitated by dysfunction in one of two interrelated processes-salivary production and oropharyngeal clearance. While medications primarily precipitate the former, dysphagia, often due to neurologic dysfunction, often causes the latter. This overabundance of saliva coupled with difficulty swallowing can predispose patients to respiratory issues, infections, and poor quality of life. There are, however, a myriad of treatment options that have shown clinical efficacy in treating this dysfunction. The purpose of this article is to present some background and etiology behind sialorrhea as well as present treatment options-non-pharmacologic, pharmacologic, surgical, and radiotherapeutic-that can help to ameliorate symptoms and improve quality of life for patients.
