Adenotonsillectomy for obstructive sleep apnea in children with cerebral palsy: Risks and benefits

OBJECTIVES

To determine outcomes following adenotonsillectomy for obstructive sleep apnea (OSA) and the impact of motor and swallowing impairment on respiratory complications in children with Cerebral Palsy (CP).

METHODS

A retrospective review of children with CP and sleep disordered breathing (SDB) who underwent adenotonsillectomy (2003-2021) was performed. Children with CP were age-matched to children without CP. Motor and swallowing function was assessed using the Gross Motor Functional Classification System (GMFCS) and the Eating and Drinking Ability Classification System (EDACS). The primary outcome was postoperative obstructive apnea-hypopnea index (OAHI). Secondary outcomes were cure rate, complications, and need for additional interventions.

RESULTS

Ninety-seven children with CP were assessed for SDB, and 74 underwent polysomnography. Moderate or severe OSA was found in 49% (36/74). Adenotonsillectomy was performed in 30% (29/97). All children who underwent adenotonsillectomy experienced an initial reduction in OAHI (31.7/h to 2.9/h, p < 0.0001). Children with CP were less likely to achieve an OAHI<1 compared with children without CP (62.5% vs 81.8%, p = 0.23). Children with CP had more postoperative complications (43.5% vs. 8.7%) and greater odds of respiratory complications compared with children without CP (OR 8.9 95% CI 2.1-37.9). Children with CP and a GMFCS score of 5 and EDACS score between 3 and 5 had more respiratory complications post-adenotonsillectomy compared to those with GMFCS<5 (p = 0.002) and EDACS<3 (p = 0.031).

CONCLUSION

Children with CP had an improved OAHI initially following adenotonsillectomy but had higher rates of post-adenotonsillectomy complications. Respiratory complications after adenotonsillectomy were more common in children with motor and swallowing impairment. Findings may provide better preoperative planning for caregivers.

Sleep in children from northeastern Brazil with congenital Zika syndrome: assessment using polysomnography

STUDY OBJECTIVES

We performed this study to describe the characteristics of sleep in children with congenital Zika syndrome through polysomnographic assessment.

METHODS

Polysomnography with neurological setup and capnography was performed. Respiratory events were scored according to American Academy of Sleep Medicine criteria. Children were classified based on neuroclinical examination as having corticospinal plus neuromuscular abnormalities or exclusively corticospinal abnormalities. Neuroradiological classification was based on imaging exams, with children classed as having supratentorial plus infratentorial abnormalities or exclusively supratentorial abnormalities.

RESULTS

Of 65 children diagnosed with congenital Zika syndrome, sleep apnea was present in 23 children (35.4%), desaturation in 26 (40%), and snoring in 13 (20%). The most prevalent apnea type was central in 15 children (65.2%), followed by obstructive apnea in 5 (21.7%) and mixed type in 3 (13%). The average of the lowest saturation recorded was slightly below normal (89.1 ± 4.9%) and the mean partial pressure of end-tidal carbon dioxide value was normal. Periodic leg movements were present in 48 of 65 children. Lower ferritin levels were observed in 84.6% of children. Palatine and pharyngeal tonsils (adenoids) were small in most children and not associated with the presence of obstructive apnea. Ventriculomegaly and subcortical and nucleus calcification were the most frequent neuroimaging findings. Supratentorial and infratentorial anomalies were present in 26.7% (16 of 60) and exclusively supratentorial changes in 73.3% (44 of 60). In the neuroclinical classification, isolated corticospinal changes were more frequent and the mean peak in capnography was lower in this group. There was no difference regarding the presence of apnea for children in the neuroclinical and neuroradiological classification groups.

CONCLUSIONS

Sleep disorders were frequent in children with congenital Zika syndrome, with central sleep apnea being the main finding.

Base of Tongue Surgery and Pediatric Obstructive Sleep Apnea

OBJECTIVE

Drug-induced sleep endoscopy-directed lingual tonsillectomy and midline posterior glossectomy have been employed for the treatment of obstructive sleep apnea in children. The purpose of this study is to evaluate outcomes in children undergoing lingual tonsillectomy, midline posterior glossectomy, or combined base of tongue reduction procedures for obstructive sleep apnea.

STUDY DESIGN

Case series with chart review.

SETTING

Tertiary care academic medical center.

METHODS

A case series was performed with chart review of pediatric patients with obstructive sleep apnea who underwent base of tongue surgery as directed by drug-induced sleep endoscopy. Pre- and postoperative obstructive apnea-hypopnea index (oAHI) was compared. Age, sex, body mass index z score, and medical history were also evaluated.

RESULTS

A total of 168 children were included, with a mean ± SD age of 8.3 ± 3.6 years. Of these patients, 101 underwent lingual tonsillectomy alone; 25, midline posterior glossectomy alone; and 42, both. Their mean oAHI improvement was 3.52 ± 8.39, 2.55 ± 5.59, and 3.70 ± 6.07, respectively. Each surgical group experienced significant improvement in sleep apnea when pre- and postoperative oAHI was compared (P < .01). Overall surgical success, as defined by oAHI <1 (or <5 without clinical symptoms), was 75% (126 patients).

CONCLUSION

When guided by drug-induced sleep endoscopy, pediatric tongue base surgery can significantly improve oAHI and thus demonstrates promising success in treating pediatric obstructive sleep apnea.

Sleep, cognition and executive functioning in young children with cerebral palsy

Children with cerebral palsy (CP) are at higher risk for sleep disturbances than their typically developing peers. In typically developing young children, lack of sufficient sleep results in deficits in cognition, behavior and executive functioning. Unfortunately, research on sleep in infancy rarely focuses on children with neurodevelopmental disabilities. Studies of older children with CP demonstrate that roughly half of children with CP have a sleep disorder, though screening for sleep disorders in children with CP is not routinely performed. Given the high prevalence of sleep abnormalities in older children with CP and the resulting adverse effects on functioning, understanding sleep derangements and how they affect cognition and executive functioning in these children at earlier ages is critical. In this chapter, we present the state of the evidence for sleep characteristics, cognition and executive functions for infants and toddlers 0-3years old with CP.
