BackgroundAspirations are frequent in children with neurological impairment. They significantly increase the risk for acute and chronic respiratory insufficiencies leading to high morbidity and mortality. Laryngeal sensation deficits have been linked to aspirations in adults and are a suspected cause for dysphagia in children. In a similar neurological circuit as swallowing, laryngeal receptors trigger coughing as a protective airway reflex. The aim of this study was to examine the association between impaired laryngeal sensation (ILS), aspiration and coughing in neurologically impaired children.Design and MethodsIn a retrospective study, 110 children with suspected dysphagia who underwent a clinical evaluation of swallowing and a flexible endoscopic evaluation of swallowing (FEES) between 2013 and 2019 in the children’s university clinic Düsseldorf were analyzed. Laryngeal sensation was tested by the endoscopic touch method. Associations were computed using χ2-test.ResultsFifty-four patients (49.1%) had neurological impairment, 56 patients (50.9%) had no or other comorbidities and served as a control cohort. Children with neurological impairment suffered from ILS significantly more often than children with no or other comorbidities (χ²(1) = 4.63, p = .031). ILS was associated with all other FEES variables but did not correlate with coughing. The symptom coughing correlated with aspiration in the group of neurologically impaired children and in children ILS.Conclusion ILS is a potential cause of aspirations in children with neurological impairment.  Physicians need to pay special attention to the occurrence of coughing in children with neurological impairment and/or ILS since it signals aspirations that took place.
