Reduction of salivary flow in patients with drooling, salivary fistulas, or chronic sialadenitis by local injection of botulinum toxin type A into the salivary glands proved to be a dependable therapy for these disorders, as shown in the present extended report on 33 patients. Side effects were not observed. The effect of toxin application lasted for approximately 3 months. Based on their results, the authors recommend botulinum toxin injection as the therapy of choice in patients with the problem of drooling.
