The Role of Airway Management on Feeding Difficulties in Children With Pfeiffer Syndrome.

BACKGROUND: Pfeiffer syndrome is characterized by craniosynostosis, mid-face hypoplasia, broad thumbs, and often multilevel airway obstruction. Airway management is often required, including the use of positive airway ventilation, nasopharyngeal airway (NPA), or tracheostomy. OBJECTIVE: The objective of this study was to assess the impact an airway adjunct can have on feeding difficulties in children with Pfeiffer syndrome. METHODS: Retrospective review of patients diagnosed with Pfeiffer syndrome from January 1998 to January 2020 at one of England's 4 supraregional Craniofacial Units, Alder Hey Children's Hospital. Speech & Language Therapy case notes and medical notes were used to gather data, as well as the Oral Feeding Score component of the UK Craniofacial Outcome Score. RESULTS: Eleven patients were included. Six patients had no airway adjunct (55%): 3 had tracheostomy (27%) and 2 patients had NPA (18%). All patients with airway adjuncts were percutaneous endoscopic gastrostomy/percutaneous endoscopic jejunostomy fed. Those who did not require an airway adjunct had an Oral Feeding Score of 4.60 (SD: 0.49). The children who went on to have an airway adjunct had a mean preintervention Oral Feeding Score of 2.4 (SD: 0.8). The mean feeding score (postairway adjunct) in the NPA group was 2.0, compared with the tracheostomy group scoring 3.0. CONCLUSIONS: Children with Pfeiffer syndrome who require airway intervention have more significant feeding problems requiring feeding intervention. Although there were small numbers included in this study, there is a suggestion that airway adjuncts can contribute to feeding difficulties, particularly NPAs.

Prevalence of dysphagia following posterior fossa tumour resection in children: the Alder Hey experience.

BACKGROUND: Surgery for posterior fossa tumours (PFTs) in children is associated with bulbar palsy and swallowing difficulties although this risk is not well defined in the literature and issues contributing to dysphagia following surgery are not fully understood. AIMS: This study aims to study the eating, drinking and swallowing function of children following PFT resection in a specialist paediatric neurosurgery centre. This included the frequency and duration of dysphagia, the risk of aspiration and the link between tumour type and dysphagia. MATERIALS AND METHODS: This is a retrospective review of children undergoing surgery for PFT between 2014 and 2019. Information was obtained from the patients' hospital and speech and language therapy (SLT) notes, oncology database and clinical letters. The International Dysphagia Diet Standardisation Initiative (IDDSI) Framework was used to describe food and fluid modifications. RESULTS: Seventy children had surgery to resect a posterior fossa tumour at Alder Hey from 2014 to 2019. Thirty-one children were included in the study following referral to SLT. Videofluoroscopy (VF) was undertaken at our institution in 68% (21/31) of cases. Fifty-two percent (11/21) of children aspirated or were considered at risk, and 55% (6/11) of those who aspirated showed silent aspiration. After 3 months, 43% (13/30) still required modified food and/or fluid textures, with this proportion reducing as time progressed. By tumour type, VF was performed in 5/7 medulloblastoma patients with 3/5 showing aspiration and 3/3 silently aspirating; in 8/9 patients with ependymoma with 4/8 patients aspirating with 2/4 showing silent aspiration; and 6/12 glioma patients with 4/6 aspirating with 1/4 showing silent aspiration. CONCLUSION: Swallowing difficulties, including silent aspiration, are an important complication of PFT resection. A proportion of children will need ongoing food and/or fluid modification. Further study into dysphagia following PFT resection is indicated.

Resonance and speech articulation after midface advancement in craniofacial dysostosis.

OBJECTIVE: This study aimed to analyze changes in resonance and speech articulation after midface advancement in syndromic craniofacial patients and to assess the influence of craniofacial diagnosis and the presence or absence of a cleft palate. METHODS: This study is a retrospective analysis of resonance and speech articulation in patients after midface advancement. This project was carried out in a multidisciplinary pediatric craniofacial service. Eighteen patients underwent midface advancement between 2002 and 2009. Three were excluded because of inadequate records or presence of tracheostomy. Midface advancement was done by Le Fort III, facial bipartition, or monobloc, either conventional surgery or distraction osteogenesis. Outcomes include perceptual assessment of articulation and resonance using GOS.SP.ASS.98 revised and recommendation for speech surgery. RESULTS: Hypernasality scores decreased in 7 patients (46.7%), and 5 patients were recommended for speech surgery. Hyponasality scores improved in 10 patients (66.7%), were unchanged in 3 patients (20%), and decreased in 2 patients (13%). Articulation changed (improved) in 1 patient (6.7%) only. Hypernasality scores decreased in 33.3% of Crouzon and 71.4% of Apert patients. Five patients had a cleft palate, 4 had Apert syndrome, and hypernasality scores decreased in 3 patients. Of 3 patients with Apert syndrome but no cleft palate, 2 (66.7%) also had a decrease in hypernasality scores. CONCLUSIONS: Our findings suggest a high incidence of deterioration in velopharyngeal function after midface advancement, particularly in Apert syndrome, regardless of the presence of a cleft, and an improvement in hyponasality, but minimal change in articulation. Larger prospective multicenter studies are required to investigate these findings further.
