Treatment of sialorrhoea with ultrasound guided botulinum toxin type A injection in patients with neurological disorders

Abstract

This is the first study to report (1) the injection of BTX-A (BOTOX) into both parotid and submandibular glands, and (2) the use of ultrasound guidance during the administration of BTX-A into salivary glands. The results suggest that the technique is safe and that BTX-A injections are effective for the treatment of sialorrhoea in patients with neurological disorders.
