===Sialorrhea===
[[Sialorrhea]] is a condition where oral secretions are unable to be eliminated, causing pooling of saliva in the mouth. This condition can be caused by various neurological syndromes such as [[Bell's palsy]], intellectual disability, and cerebral palsy. Injection of botulinum toxin type-A into salivary glands is useful in reducing the secretions.<ref>{{cite journal |vauthors = Khan WU, Campisi P, Nadarajah S, Shakur YA, Khan N, Semenuk D, McCann C, Roske L, McConney-Ellis S, Joseph M, Parra D, Amaral J, John P, Temple M, Connolly B |title = Botulinum toxin A for treatment of sialorrhea in children: an effective, minimally invasive approach |journal = Archives of Otolaryngology–Head & Neck Surgery |volume = 137 |issue = 4 |pages = 339–344 |date = April 2011 |pmid = 21242533 |doi = 10.1001/archoto.2010.240 |doi-access = free |title-link = doi }}</ref>
