Ultrasound-guided Botulinum Toxin Injection into the Salivary Glands for Treating Sialorrhea in a Case of Small-cell Lung Cancer

Abstract

Sialorrhea or excessive drooling is an important problem known as saliva spillage from the mouth. Drooling may accompany many diseases, especially chronic neurological diseases and other chronic diseases. A 57-year-old female patient presented with a complaint of drooling that started after concurrent chemotherapy and radiotherapy due to small-cell lung cancer. The patient's complaints were significantly reduced with an ultrasound-guided botulinum toxin injection into the salivary glands.
