ABSTRACT: Introduction
Subjects with Rett syndrome (RS) develop invariably severe motor deterioration resulting in swallowing difficulties that may produce excessive drooling. Hypersalivation can cause discomfort due to hygienic problems and may complicate with oral and respiratory dysfunctions. The aim of this study is to evaluate the response to treatment with botulinum toxin (BTX) for hypersalivation and to identify possible benefits of saliva reduction on oral motor and respiratory disorders of patients with RS.Methods
Five consecutive patients with RS and hypersalivation were treated with incobotulinumtoxin A injected in salivary glands with ultrasound guidance. Severity of excessive drooling was assessed with the Thomas-Stonell and Greenberg Scale (TGSC) and the clinical impact of the treatment was evaluated using three selected items of RS Assessment Rating Scale (R.A.R.S.): eating habits, dyspnoea and bruxism. Scale rating was performed before BTX injection (T0), 4 (T1) and 12 (T2) weeks after.Results
Scores of TGSC and R.A.R.S. (for eating and bruxism) were reduced significantly after therapy at T1.Conclusions
BTX treatment for sialorrhea in RS is effective in reducing saliva production and may also improve oral motor functions.
