Abstract
This study was a systematic review and meta-analysis that assessed the risk of aspiration pneumonia in children with laryngeal penetration or tracheal aspiration via a video-fluoroscopic study (VFSS) and compared the results to those for children with neither condition. Systematic searches were conducted using databases, including PubMed, Cochrane Library, and Web of Science. Meta-analysis was used to obtain summary odds ratios (OR) and 95% confidence intervals (CI). The overall quality of evidence was assessed using the grading of recommendations, assessment, development, and evaluation (GRADE) criteria. In total, 13 studies were conducted with 3159 participants. Combined results from six studies showed that laryngeal penetration on VFSS may be associated with aspiration pneumonia compared to no laryngeal penetration; however, the summary estimate was imprecise and included the possibility of no association (OR 1.44, 95% CI 0.94, 2.19, evidence certainty: low). Data from seven studies showed that tracheal aspiration might be associated with aspiration pneumonia compared to no tracheal aspiration (OR 2.72, 95% CI 1.86, 3.98, evidence certainty: moderate). The association between aspiration pneumonia and laryngeal penetration through VFSS seems to be weaker than that for tracheal aspiration. Prospective cohort studies with clear definitions of laryngeal penetration and that measure clinical and patient reported outcomes are needed to further define the association between laryngeal penetration and aspiration pneumonia.

Abstract
INTRODUCTION Dysphagia affects several children in USA and around the globe. Videofluoroscopic Swallow Study (VFSS) and Fiberoptic Endoscopic Evaluation of Swallowing (FEES) are the most objective studies to define swallowing function. The presence of tracheal aspiration during VFSS or FEES in children with dysphagia is associated with an increased risk of aspiration pneumonia. However, the association of laryngeal penetration with aspiration pneumonia remains unclear. This systematic review aims to assess the risk of aspiration pneumonia in children with dysphagia with laryngeal penetration on VFSS/FEES and compare it with children with tracheal aspiration and children with neither tracheal aspiration nor laryngeal penetration. METHODS AND ANALYSIS This study will be a systematic review and meta-analysis. Systematic electronic searches will be conducted on PubMed, EMBASE, Web of Science, CINHAL, Scopus, Cochrane CENTRAL, LILACS and WHO Global Index Medicus. We will include studies published through 6 October 2021. Primary outcome will be the incidence of aspiration pneumonia. Secondary outcomes will be incidence of hospitalisation, paediatric intensive care unit admission, enteral tube requirement, growth, symptoms improvement and mortality. The Cochrane Risk of Bias In Non-Randomised Studies of Interventions tool will be used to assess the risk of bias. Meta-analysis will be used to pool the studies. We will pool dichotomous outcomes to obtain an odd ratio (OR) and report with 95% CI. Continuous outcomes will be pooled to obtain mean difference and reported with 95% CI. Overall grade of evidence will be assessed using Grading of Recommendations Assessment, Development and Evaluation (GRADE) criteria, and findings will be presented in a summary of findings table. ETHICS AND DISSEMINATION This study is a systematic review without contact with patients. Therefore, IRB approval is not required. Authors consent to publishing this review. Data will be kept for review by editors and peer reviewers. Data will be available to general public on request. PROSPERO REGISTRATION NUMBER CRD42020222145.

Abstract
OBJECTIVES/HYPOTHESIS Timing and indication for surgical intervention is a major challenge in managing pediatric oropharyngeal dysphagia. No study has evaluated a natural course of swallowing dysfunction in otherwise healthy infants. Our objective was to review the outcomes and time to resolution of abnormal swallow in infants with aspiration. STUDY DESIGN Retrospective case series at a tertiary children's hospital. METHODS Fifty patients under 1 year old with aspiration on a modified barium swallow study were included. Patients born <34 weeks, with medical or genetic comorbidities, or who underwent surgical intervention for aspiration were excluded. Patients were followed until aspiration resolved on a swallow study. Kaplan-Meier survival analysis was performed. RESULTS Forty patients (25 patients [50%] by 6 months, 10 [20%] by 1 year, three [6%] by 2 years, and two [4%] at the end of the follow-up interval) were recommended a normal diet, and 10 patients (20%) were still aspirating by the end of the follow-up interval. Median time to resolution was 202 ± 7 days (range, 19-842 days), probability 48% (95% confidence interval [CI]: 0.34-0.62). The probability of resolution at 6 months was 46% (95% CI: 0.4-0.68), at 1 year was 64% (95% CI: 0.51-0.77), at 2 years was 76% (95% CI: 0.64-0.88), and at the end of the follow-up interval 81.3% (95% CI: 0.7-0.92). CONCLUSIONS The majority of infants with aspiration and without any other major comorbidities improved within 1 year. Future research should be directed toward better understanding swallowing dysfunction in neurologically normal infants. LEVEL OF EVIDENCE 4 Laryngoscope, 130:514-520, 2020.
