The Treatment of Drooling by Ultrasound‐Guided Intraglandular Injections of Botulinum Toxin Type A Into the Salivary Glands

Abstract

With the procedure described, it is possible to accurately inject BTX directly into the glandular parenchyma and to visualize spreading of the fluid in the glandular parenchyma. It is found to be a safe method that guarantees an optimal clinical effect and avoids potentially harmful side effects. We recommend ultrasound guidance if injections of BTX into the salivary glands are considered.
