Management of oropharyngeal dysphagia in the neurologically intact and developmentally normal child

Brain imaging abnormalities in children with dysphagia with aspiration: A retrospective study

OBJECTIVE

Head imaging is often performed in children with persistent dysphagia with aspiration to evaluate for Chiari malformations that may be associated with dysphagia. Unfortunately, the frequency of Chiari malformations or other head imaging abnormalities in children who aspirate is unknown. The goal of this study is to determine the frequency of head imaging abnormalities in children with evidence of aspiration or penetration on video fluoroscopic swallow study (VFSS).

SETTING

Tertiary Children's Hospital.

METHODS

We performed retrospective analysis of children with a diagnosis of aspiration evaluated at our center from January 2010 through April 2021. In this study, we included children with VFSS confirmed aspiration or penetration, brain magnetic resonance imaging (MRI) performed at our center, and without known genetic, congenital craniofacial, or neurologic abnormalities.

RESULTS

Of the 977 patients evaluated in our system during that time with a diagnosis of aspiration, 185 children met the inclusion criteria. Eight children were diagnosed with Chiari malformations (4.3%) and 94 head MRIs were abnormal (51.4%). There was no difference in VFSS findings (frequency of aspiration, penetration, penetration-aspiration score, or recommended thickness of liquid) in children with a Chiari malformation versus other abnormalities or normal brain imaging. The majority of other non-Chiari brain imaging abnormalities were nonspecific. There was no difference in VFSS findings in children with abnormal MRI findings versus normal MRI.

CONCLUSIONS

Brain imaging abnormalities are common in children who aspirate. Intervenable lesions are rare. Further studies are required to determine patients that will most likely benefit from brain imaging.

Screening of Swallowing and Feeding-Related Problems in Typically Developing Children

The aim of this study was to define swallowing and feeding-related problems among typically developing children aged between 2 and 6 years. The presence of food selectivity, limited appetite, chewing dysfunction, and dysphagia signs was questioned and scored as "absent" or "present" according to parent report. Children were divided into 2 groups: children with swallowing and feeding disorders and children without swallowing and feeding disorders. The Turkish version of the Behavioral Pediatrics Feeding Assessment Scale (T-BPFAS) was used to evaluate feeding behaviors of children, and Turkish version of the Feeding/Swallowing Impact Survey (T-FS-IS) was used to measure the impact on caregivers. A total of 234 children were included. Food selectivity was defined in 62.4% (n = 146), limited appetite in 26.9% (n = 63), and chewing dysfunction in 7.3% (n = 17). The most common dysphagia-related sign was coughing. There were significant differences between groups in terms of both T-BPFAS and T-FS-IS (P < .001). In conclusion, children with typical development have experienced a wide range of swallowing and feeding-related problems, which have an impact on mothers' perceptions regarding feeding and their quality of life.

Isolated bulbar palsy and dysphagia in children with respiratory symptoms

Oropharyngeal dysphagia can cause chronic aspiration leading to significant respiratory symptoms. When dysphagia is diagnosed, an underlying cause is sought. We present a case series of 15 children diagnosed aged 6 months to 5 years (mean 2y 5mo; 11 males, four females) over a 6-year period, who were found to have an isolated bulbar palsy on genioglossus electromyography, with no accompanying neurological or neurodevelopmental disorder. Eight children had dysphagia but a normal EMG. In those with isolated bulbar palsy, management included thickened fluids (n=13), cooled boiled water (n=1), and nasogastric tube feeding (n=1). Follow-up over 1 to 8 years (mean 5y) showed complete resolution in six children, improvement in four children, and no improvement in five children (including two requiring fluids via a gastrostomy). Eight children no longer had any respiratory symptoms. Isolated bulbar palsy is under-recognized and has not been reported previously as a cause of significant dysphagia in children.

Pediatric Dysphagia: Physiology, Assessment, and Management

Infancy and childhood represent a time of unparalleled physical growth and cognitive development. In order for infants and children to reach their linear and neurological growth potential, they must be able to reliably and safely consume sufficient energy and nutrients. Swallowing difficulties (dysphagia) in pediatric populations can have a detrimental effect on dietary intake and, thus, growth and development. As a result, it is imperative to accurately identify and appropriately manage dysphagia in pediatric populations. This article provides an overview of dysphagia in children, as well as common causes of childhood swallowing difficulties, populations at risk for pediatric dysphagia, techniques used to assess swallowing in pediatric patients, and the current treatment options available for infants and children with dysphagia.

Supraglottoplasty in Premature Infants with Laryngomalacia

Purpose

Prematurity is thought to be to be an independent risk factor for supraglottoplasty (SGP) failure. The purpose of this study was to compare the outcomes of supraglottoplasty in premature infants with congenital laryngomalacia (LM) with that of term infants.

Study Design

Case series with chart review.

Setting

Tertiary-care pediatric institution.

Methods

Analysis was performed on 325 consecutive patients undergoing SGP between 2004 and 2012. Patients older than 12 months age or with syndrome, neurologic, or cardiac comorbidities were excluded. Resolution of airway symptoms after SGP was considered successful while revision SGP and tracheostomy were considered failures. The rates of secondary airway lesions (SAL), dysphagia, and gastrostomy tube (GT) placement were also compared.

Results

A total of 176 infants (136 term, 40 preterm) were identified. SGP was successful in 92.7% term and 90% preterm infants with no significant difference ( P = .5865). Incidence of revision SGP and tracheostomy was similar among the groups. The outcomes of SGP were the same in all groups stratified by age. Incidence of SAL was significantly higher in preterm (72.5%) compared to term infants (34.6%, P = .0002). Dysphagia rates in the follow-up were higher in preterm (32.5%) versus term infants (6.6%, P < .001). The rate of GT insertion was significantly greater ( P = .003) in preterm (27.5%) than term infants (6.6%). The preoperative dysphagia, persistent dysphagia, and GT in follow-up was significantly higher when gestation age <32 weeks (25%, P = .0168).

Conclusion

Supraglottoplasty outcomes in term and preterm infants were similar irrespective of gestation age. Higher rates of dysphagia in follow-up are seen when gestation age <32 weeks.
