Silva MA, da Silveira MMF, Pedrosa BRV, Dos Santos RTNT, de Farias ZBBM, Sobral APV. A systematic review of the perspectives of botulinum toxin use on the quality of life of neurological patients with drooling. Clin Oral Investig 2024; 28:322. [PMID: 38758415 DOI: 10.1007/s00784-024-05718-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/24/2024] [Accepted: 05/08/2024] [Indexed: 05/18/2024]
Abstract
OBJECTIVE To investigate the effectiveness of botulinum toxin in the salivary glands of patients with neurological impairment and drooling and its impact on the quality of life. MATERIALS AND METHODS This systematic review was registered with the International Prospective Register of Systematic Reviews (CRD 42,023,435,242) and conducted using the Preferred Reporting Items for Systematic Reviews and Meta-analyses. An electronic search was performed in the PubMed/MEDLINE, Embase, Scopus, Cochrane Library, and clinical trial databases until August 2023, no language restriction. Cohort studies and randomized clinical trials of patients diagnosed with drooling and neurological impairment who used botulinum toxin on the salivary gland were included, which evaluated subjective quality of life parameters. The risk of bias was assessed using the Joanna Briggs Institute Critical Appraisal Checklist and Risk of Bias 2 tools. The certainty of the evidence was analyzed using the Grading of Recommendations Assessment, Development, and Evaluation approach. RESULTS Eight studies involving 317 patients were included. All studies, through subjective parameters, suggested the effectiveness of botulinum toxin in reducing drooling, resulting in an improvement in the quality of life. Three studies demonstrated improvements in swallowing and four in cases of respiratory diseases. Two clinical trials had a high risk of bias, whereas one had low risk. The five cohort studies that were evaluated had a high risk of bias. The certainty of the evidence was considered low. CONCLUSIONS Based on the patient/caregivers' perception of improvement in drooling, dysphagia, and respiratory symptoms, it can be inferred that botulinum toxin application reduces subjective drooling in neurologically compromised patients. Its impact contributes to the general well-being and quality of life. CLINICAL RELEVANCE Injection of botulinum toxin into the salivary glands can be considered an alternative technique to surgical or medicinal approaches in reducing drooling. It is effective, less invasive and without significant side effects. It promotes a positive impact on the well-being and quality of life of neurological patients.

Abstract
OBJECTIVE Botulinum toxin A is known to be effective and safe in managing sialorrhea in pediatric patients; however, there is no consensus on a protocol for optimal injection sites and appropriate dosing for injection. METHODS This review was performed using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Protocol. PubMed, EMBASE, and other databases were queried to identify articles that evaluated botulinum toxin type A for the treatment of sialorrhea in the pediatric population. A total of 405 studies were identified. After applying inclusion and exclusion criteria, 31 articles were included for review. RESULTS A total of 14 studies evaluated 2-gland injections, and 17 studies evaluated 4-gland injections. Of the 31 studies included, one study assessed incobotulinumtoxinA (Xeomin®) the remaining all used onabotulinumtoxinA (Botox®). For 2-gland injection studies, a combined total of 899 participants were reviewed, where 602 participants received 50 units into their submandibular glands, while 262 participants received 30 to 50 units. Among 4-gland injection studies, there was a combined total of 388 participants, with the most prevalent dosage utilized being 60 to 100 units in 230 participants, followed by 100 units total in 77 participants. The most common adverse event was dysphagia which resolved in nearly all cases. Three studies aimed to examine 2-gland versus 4-gland injections, with 2 of the studies concluding 4-gland injection was superior. CONCLUSIONS The strength of evidence suggests that the dosing of 50 units total of onabotulinumtoxinA to the submandibular glands is safe and effective in the pediatric population. For 4-gland injections, bilateral submandibular and parotid gland injections of 60 to 100 units total is the safe and effective dosage. There is no substantial evidence comparing 4-gland injections to 2-gland injections, but research thus far suggests 4-gland injections to be superior. Future study is needed to evaluate incobotulinumtoxinA and abobotulinumtoxinA dosages in the pediatric population.

Abstract
Respiratory illness is the leading cause of mortality in children with cerebral palsy (CP). Although risk factors for developing chronic respiratory illness have been identified, comprehensive clinical care recommendations for the prevention and management of respiratory illness do not currently exist. We invited over 200 clinicians and researchers from multiple disciplines with expertise in the management of respiratory illness in children with CP to develop care recommendations using a modified Delphi method on the basis of the RAND Corporation-University of California Los Angeles Appropriateness Method. These recommendations are intended for use by the wide range of practitioners who care for individuals living with CP. They provide a framework for recognizing multifactorial primary and secondary potentially modifiable risk factors and for providing coordinated multidisciplinary care. We describe the methods used to generate the consensus recommendations, and the overall perspective on assessment, prevention, and treatment of respiratory illness in children with CP. WHAT THIS PAPER ADDS: The first consensus statement for preventing and managing respiratory disease in cerebral palsy (CP). Risk factors for respiratory disease in CP should be identified early. Individuals with CP at risk of respiratory disease require regular assessment of risk factors. Effective partnerships between multidisciplinary teams, individuals with CP, and families are essential. Treatment of respiratory disease in individuals with CP must be proactive.

Abstract
BACKGROUND work still needs to be done to measure the impact of sialorrhea on quality of life and define the efficacy of different therapies. The Drooling Impact Scale showed good validity and sensitivity to change, especially after botulinum toxin injection. The aim of this study is to present its French translation and to explore its validity, reliability and responsiveness to change in a group of children with Cerebral Palsy. METHODS multicentre study at six rehabilitation centres in France. Children with Cerebral Palsy aged 4-18 years with sialorrhea problems were included (n = 55), either in a control group (n = 33) or in the intervention group (n = 22, with 3 drug treatment and 19 botulinum toxin injections). The French Drooling Impact Scale was administered twice, 1 month apart. RESULTS The French Drooling Impact Scale total score at inclusion was meanly 53.9 (Standard Deviation 11.9) in the stable control group and 66.0 (16.1) in the intervention group (p = 0.0058). The validity of the scale was established, as well as an adequate internal consistency (Cronbach's α = 0.71); correlations between each item and the total score were found between 0.5 and 0.71 except for item 5 (r = 0.38) and item 7 (0.41). The test-retest reliability in stable children was good (Lin coefficient = 0.83, bias correction factor = 0.92 and Pearson correlation coefficient = 0.89). There was a high responsiveness to change, mean change was -40.0 in the intervention group and -3.6 in the stable group (p < 0.0001), with Standard Error of Measurement = 2.6. CONCLUSION the French Drooling Impact Scale has shown sufficient clinometric properties to be used now by clinicians or researchers.IMPLICATIONS FOR REHABILITATIONThe Drooling Impact scale has now its French version.The French version of the Drooling Impact Scale has shown its validity and a good test-retest reliability.The responsiveness to change was explored in a group of children undergoing saliva-control interventions and the scale was able to show a big change.The authors recommend to use this questionnaire in a semi-directed interview conducted by a health professional.

Abstract
Cerebral palsy (CP) is the most common cause of disability in childhood. Respiratory illness is the most common cause of mortality, morbidity, and poor quality of life in the most severely affected children. Respiratory illness is caused by multiple and combined factors. This review describes these factors and discusses assessments and treatments. Oropharyngeal dysphagia causes pulmonary aspiration of food, drink, and saliva. Speech pathology assessments evaluate safety and adequacy of nutritional intake. Management is holistic and may include dental care, and interventions to improve nutritional intake, and ease, and efficiency of feeding. Behavioral, medical, and surgical approaches to drooling aim to reduce salivary aspiration. Gastrointestinal dysfunction, leading to aspiration from reflux, should be assessed objectively, and may be managed by lifestyle changes, medications, or surgical interventions. The motor disorder that defines cerebral palsy may impair fitness, breathing mechanics, effective coughing, and cause scoliosis in individuals with severe impairments; therefore, interventions should maximize physical, musculoskeletal functions. Airway clearance techniques help to clear secretions. Upper airway obstruction may be treated with medications and/or surgery. Malnutrition leads to poor general health and susceptibility to infection, and improved nutritional intake may improve not only respiratory health but also constipation, gastroesophageal reflux, and participation in activities. There is some evidence that children with CP carry pathogenic bacteria. Prophylactic antibiotics may be considered for children with recurrent exacerbations. Uncontrolled seizures place children with CP at risk of respiratory illness by increasing their risk of salivary aspiration; therefore optimal control of epilepsy may reduce respiratory illness. Respiratory illnesses in children with CP are sometimes diagnosed as asthma; a short trial of asthma medications may be considered, but should be discontinued if ineffective. Overall, management of respiratory illness in children with CP is complex and needs well-coordinated multidisciplinary teams who communicate clearly with families. Regular immunizations, including annual influenza vaccination, should be encouraged, as well as good oral hygiene. Treatments should aim to improve quality of life for children and families and reduce burden of care for carers.

Abstract
OBJECTIVE To describe the effects of salivary gland Botulinum Toxin-A (SG BoNT-A) on children with drooling due to neurological dysfunction. METHODS This was a 3½-year prospective observational case series design of children referred for SG BoNT-A injections at a pediatric hospital (2010-2014). Outcomes were parent-reported severity, frequency, impact of drooling, and respiratory morbidity; and, from hospital records, number of respiratory hospital admissions. RESULTS Out of 17 children treated, complete data were available for 15 (including 8 boys) aged 3-14 years (Mean = 9.9 years; SD = 3.4), with a combined total of 71 injections. Most had cerebral palsy (n = 11), classified as Level V (n = 10) or IV (n = 1) on the Gross Motor Function Classification Scale (GMFCS). In almost all instances, parents reported reductions in severity, frequency, and impact of drooling, and parent-reported respiratory morbidity. Among those with posterior drooling (n = 12), most children (n = 10) did not have advanced respiratory disease. A trend towards reduced respiratory-related hospital admissions was observed during SG BoNT-A treatment periods. CONCLUSION SG BoNT-A can improve severity, frequency, and impact of drooling. It can also reduce respiratory-related hospital admissions in children with posterior drooling without advanced respiratory disease. For children with advanced respiratory disease, it may reduce severity and impact of drooling.

Abstract
BACKGROUND Respiratory disease is a leading cause of hospitalizations and deaths in young people with cerebral palsy (CP). It is insidious and multifactorial. Clinical management can be complex. This systematic review describes effects of interventions for the prevention and management of respiratory disease in young people with CP. METHODS Nine databases (Cochrane, CINAHL, Embase, EMCare, MEDLINE, PEDro, OpenGrey, ScienceDirect, and SpeechBITE) were searched. Eligibility criteria were as follows: the population included at least 50% individuals with CP aged under 26 years, the intervention was for chronic respiratory illness, the outcomes were any measurable indicators of respiratory health or morbidity; the study design could be any original study reporting effects of an intervention on measurable outcomes, and the study was published January 1998 or later. The American Academy for Cerebral Palsy and Developmental Medicine methodology guided study appraisal and synthesis. The review was registered with PROSPERO (reference number CRD42018086314). RESULTS The search yielded 3,347 papers; 37 papers (reporting 34 studies) of these met the eligibility criteria. They included 582 participants with CP (ranging from 1 to 77 across studies) with ages from 5 months to 25 years. Interventions were diverse and included: airway clearance techniques, exercise, positioning, mealtime management, salivary management, upper airway interventions, antibiotics, gastro-intestinal interventions, and spinal surgery. There were no interventions aimed at prevention of respiratory disease in this population. Research designs were classified as Levels 2 (n = 3), 3 (n = 2), 4 (n = 25), and 5 (n = 4). CONCLUSIONS Evidence for most respiratory interventions for young people with CP is absent or weak. No controlled trials demonstrated significant effects on respiratory morbidity, owing to their scarcity, weak designs, and inadequate power. There is an urgent need for well-designed prospective controlled studies investigating prevention and management of respiratory disease in young people with CP.

Abstract
PURPOSE OF REVIEW Our goal is to present the most up-to-date options in the surgical management of drooling in the paediatric population. While the clinical assessment of the drooling child and conservative management options are discussed, this review focuses on the most recent evidence for surgical interventions to treat drooling in children. RECENT FINDINGS In terms of advances in the management of drooling, further experience and outcomes with the use of botulinum toxin injections is discussed. Moreover, the latest evidence-base for salivary duct ligation and relocation procedures are presented. Finally, the trans-oral approach to submandibular gland excision for the management of drooling may gain popularity through the aim of reducing surgical morbidity. SUMMARY The drooling child should be managed with an evidence-based stepwise approach delivered by a multidisciplinary team (MDT). Children with normal neurological development should be treated conservatively through parental reassurance. There are numerous interventions available for the drooling child with impaired neuromuscular development. When conservative measures fail, treatment options include botulinum toxin injections and surgical procedures such as salivary duct ligation, salivary duct relocation and salivary gland excision. Management must be targeted to the individual needs and comorbidities of the child to maximise treatment outcomes.

Abstract
BACKGROUND AND PURPOSE Drooling is a challenging entity to manage. Botulinum toxin A (BOTOX-A) infiltration of salivary glands is a promising alternative to surgical treatment. This study aims to assess the outcome of BOTOX-A salivary glands infiltration in children with drooling. METHODS Patients treated between January 2012 and March 2015 were enrolled. BOTOX-A was injected in the parotid and submandibular glands under ultrasound control and general inhalational anesthesia. The outcome was evaluated through the DSFS: Drooling Severity (1-best to 5-worst) and Frequency (1 to 4) Scale, that was applied before treatment, and 1-, 3-, and 6-month after injection. The inclusion criteria were a DSS ≥4 and/or DFS ≥3. Statistical significance was set at 5%. RESULTS There were 17 patients aged 12.1±5.1 [4-19]years, all of them with neurologic impairment. After the first injection, 13 (76.5%) patients had reduction of the severity (S) and 12 (70.6%) of the frequency (F) scale; in 6 (35.5%) patients drooling resolved completely. Pre-treatment S+F score was 8.59±0.71 [7-9]; it decreased significantly to 4.65±2.32 (p=0.001) at 1-month post-injection evaluation. At 3-month and 6-month the scores were also significantly lower than the pre-treatment one (4.00±1.96, p=0.002; 5.36±2.20, p=0.005; respectively), but there was a significant increase between the 3-month and 6-month evaluations (p=0.01). With a follow-up of 20.1±9.2 [4-38] months, 4 out of the 13 successful injections needed a second one after 7.5±3.1 [3-10] months. The patient with the longest time not requiring re-injection had 28months of follow-up. One (6%) patient presented mild dysphagia that regressed spontaneously. All but two (88%) parents/caregivers would repeat the treatment. CONCLUSIONS BOTOX-A seems to be an effective minimal invasive treatment for drooling with few complications. After 6months the need for re-injection becomes substantial but it may not be necessary for several months. Further studies are needed to establish the most effective dosage and frequency of injections. LEVEL OF EVIDENCE IV.

Abstract
BACKGROUND After the age of 4 years, drooling becomes pathological and impacts the quality of life of children with cerebral palsy. Intraglandular injection of Botulinum toxin is one of the treatments available to limit this phenomenon. AIMS The objectives of this review were to validate the efficacy of Botulinum toxin injections for drooling in children with cerebral palsy, determine recommendations and identify potential side effects. METHODS We conducted a literature review from 2001 in the following databases: Embase, Pubmed and Cochrane using the keywords: sialorrhea, drooling, hypersalivation, Botulinum toxin, cerebral palsy and children. Only the articles evaluating the efficacy of Botulinum toxin in children with cerebral palsy over the age of 4 were researched. RESULTS Eight studies were found: 2 case studies, 3 open and non-controlled studies and 3 randomized controlled trials. Efficacy results in this indication are quite encouraging and the use of BTX injections is safe but the overall level of evidence of these studies was quite low. CONCLUSION However, intraglandular injection of Botulinum toxin has a place among the therapeutic array available for the management of sialorrhea in this population even if no standardized protocol is available yet.

Abstract
AIM The aim of this paper was to systematically review the efficacy and safety of botulinum toxin (BoNT) injections to the salivary glands to treat drooling in children with cerebral palsy and neurodevelopmental disability. METHOD A systematic search of The Cochrane Central Register of Controlled Trials, PubMed, CINAHL (Cumulative Index to Nursing and Allied Health Literature), EMBASE, and the Physiotherapy Evidence Database (PEDro) was conducted (up to 1 October 2011). Data sources included published randomized controlled trials (RCTs) and prospective studies. RESULTS Sixteen studies met inclusion criteria. Three outcome measures support the effectiveness of BoNT for drooling. One RCT found an almost 30% reduction in the impact of drooling on patients' lives, as measured by the Drooling Impact Scale (mean difference -27.45; 95% confidence interval [CI] -35.28 to -19.62). There were sufficient data to pool results on one outcome measure, the Drooling Frequency and Severity Scale, which supports this result (mean difference -2.71; 95% CI -4.82 to -0.60; p<0.001). There was a significant reduction in the observed number of bibs required per day. The incidence of adverse events ranged from 2 to 41%, but was inconsistently reported. One trial was terminated early because of adverse events. INTERPRETATION BoNT is an effective, temporary treatment for sialorrhoea in children with cerebral palsy. Benefits need to be weighed against the potential for serious adverse events. More studies are needed to address the safety of BoNT and to compare BoNT with other treatment options for drooling.
