Abstract
OBJECTIVE Adenotonsillectomy is one of the most common surgical procedures performed on children. Caregivers are often concerned about voice change after the procedure, and such concerns remain unsettled. This meta-analysis analyzed voice change in children after adenotonsillectomy. DATA SOURCES The PubMed, Medline, EMBASE, and Cochrane databases. REVIEW METHODS The study protocol was registered on PROSPERO. Two authors independently searched for articles using keywords "adenoidectomy," "tonsillectomy, "voice," "nasalance,"and "speech." English articles specifying voice changes after adenotonsillectomy were pooled with standardized mean difference (SMD) using random-effects model. Evaluation methods were computerized acoustic voice analysis, aerodynamic analysis, nasometer, rhinomanometry, evaluations from a speech-language pathologist or otolaryngologist, and a caregiver assessment questionnaire. RESULTS Twenty-three studies with 2154 children were analyzed (mean age: 8.0 y; 58% boys; mean sample size: 94 children). Due to insufficient data for other outcome variables, this meta-analysis only summarized changes in the computerized acoustic voice analysis 1 month and 3 months after surgery. The computerized acoustic analysis revealed significant changes in jitter (SMD = -0.36; 95% confidence interval [CI]: -0.60 to -0.11), shimmer (SMD = -0.34; 95% CI: -0.57 to -0.11), and soft phonation index (SMD = -0.36; 95% CI: -0.57 to -0.15) at 1 month after surgery. Parameters including fundamental frequency, jitter, noise-to-harmonics ratio, and shimmer were not significantly changed at 3 months after surgery. CONCLUSIONS This meta-analysis observed small improvements in jitter, shimmer, and soft phonation index 1 month after surgery. No significant effects were observed in voice outcomes 3 months after surgery. Laryngoscope, 134:2538-2550, 2024.

Kang KT, Hsu WC. Efficacy of adenotonsillectomy on pediatric obstructive sleep apnea and related outcomes: A narrative review of current evidence. J Formos Med Assoc 2024; 123:540-550. [PMID: 37718211 DOI: 10.1016/j.jfma.2023.09.004] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/28/2023] [Revised: 08/18/2023] [Accepted: 09/05/2023] [Indexed: 09/19/2023] Open
Abstract
This review summarizes the current evidence in systematic reviews, meta-analysis and randomized controlled trials regarding adenotonsillectomy outcomes in pediatric obstructive sleep apnea (OSA). Adenotonsillectomy is effective in treating OSA in children without co-morbidities, despite postoperative residual OSA remained in roughly half of these children. For children with comorbidities such as Down syndrome, Prader-Willi syndrome, sickle cell disease, or cerebral palsy, adenotonsillectomy is less effective and associated with more postoperative complications than that in children without comorbidities. For other OSA-related outcomes, evidence from meta-analyses and randomized controlled trials confirm adenotonsillectomy results in improvement of subjective OSA-related outcomes (e.g. symptoms, behaviors, and quality of life), but the results in objective OSA-related outcomes (e.g. cardiometabolic parameters or neurocognitive functions) are inconsistent. Future studies should focus on randomized controlled trials comparing objective OSA-related outcomes and the long-term effects of adenotonsillectomy in children with OSA.

[PMID: 37917282 PMCID: PMC11136838 DOI: 10.1007/s11325-023-02945-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/05/2023] [Revised: 10/17/2023] [Accepted: 10/23/2023] [Indexed: 11/04/2023]
Abstract
PURPOSE This study aimed to conduct a meta-analysis and systematic review of drug-induced sleep endoscopy (DISE) in pediatric conventional obstructive sleep apnea-hypopnea syndrome (OSAHS) without previous upper airway surgery, or comorbidity, to evaluate the change in treatment strategies and to identify obstructive sites observed during DISE. This study aimed to explore the role of DISE in the management of pediatric conventional OSAHS. METHODS A comprehensive search was conducted using both computerized and manual methods to retrieve relevant case studies on DISE-guided treatment of pediatric conventional OSAHS from databases including PubMed, EMBASE, Cochrane Library, Web of Science, CNKI, WF, and VIP database. The search period extended from database inception to January 2023. Strict inclusion and exclusion criteria were applied to select relevant literature, and data extraction was performed accordingly. Meta-analysis was conducted using the Stata 16.0 software. RESULTS A total of 761 patients from four studies were included in the meta-analysis. All pediatric patients had no history of upper airway surgery, craniofacial abnormalities, or syndromes other than OSAHS. The quality assessment revealed that the included studies were of low methodological quality and consisted of non-randomized case studies. Meta-analysis results indicated that in pediatric patients with OSAHS, the obstruction rates observed during DISE were as follows: nasopharyngeal (adenoid) obstruction 93%, soft palate obstruction 35%, oropharyngeal (tonsil) obstruction 76%, tongue base obstruction 32%, supraglottic obstruction 31%, and multi-level obstruction 60%. DISE led to a change in the conventional surgical approach in 45% (95% CI: 29-60%) of patients with OSAHS, providing individualized treatment plans. Postoperative symptoms and sleep-related parameters improved significantly compared to preoperative values, with DISE findings possibly enhancing surgical success rates and potentially avoiding unnecessary procedures. CONCLUSION In some cases, DISE may potentially lead to alterations in conventional surgical approaches for children with OSAHS who had no history of upper airway surgery, craniofacial abnormalities, or other syndromes.. The results of our meta-analysis were in favor of DISE-directed approach for pediatric conventional OSAHS. However, further high-quality randomized controlled trials (RCTs) are warranted in future research to investigate the role of DISE in the management of pediatric OSAHS.

Abstract
Obstructive sleep apnea (OSA) is commonly observed in children with Down syndrome (DS) and may affect their physical and psychological development. Currently, adenotonsillectomy is the first line treatment option for paediatric patients with OSA. However, surgical outcomes for such patients are not satisfactory. In this study, we analysed the efficacy and safety of adenotonsillectomy in the treatment of children with obstructive sleep apnea and Down syndrome. We systematically searched the PubMed, Web of Science, EMBASE, and the Cochrane databases and pooled data from nine relevant studies involving 384 participants. Subsequently, we analysed four outcomes in polysomnography, namely: net postoperative changes in the apnea-hypopnea index (AHI), the minimum oxygen saturation, sleep efficiency, and arousal index. Meta-analysis of the AHI showed a decrease of 7.18 events/h [95% CI (-9.69, -4.67) events/h; p < 0.00001] and an increase in the minimum oxygen saturation of 3.14% [95% CI (1.44, 4.84) %; p = 0.0003]. There was no significant increase in sleep efficiency [MD 1.69%, 95% CI (-0.59, 3.98) %; p = 0.15], but the arousal index significantly decreased by -3.21 events/hour [95% CI (-6.04, -0.38) events/h; p < 0.03]. In addition, the overall success rate was 16% (95% CI, 12%-21%) for postoperative AHI < 1 and 57% (95% CI, 51%-63%) for postoperative AHI <5. The postoperative complications recorded included airway obstruction and bleeding. This study demonstrated the efficacy of adenotonsillectomy as a treatment option for OSA. However, it is important to note that residual OSA and potential postoperative complications require further attention in future studies.

Abstract
OBJECTIVE The utility of REM AHI in managing pediatric obstructive sleep apnea (OSA) is not fully understood. This study aimed to evaluate the relationship of preoperative REM AHI to postoperative persistence of OSA in children who underwent adenotonsillectomy. METHODS This retrospective chart review identified children under the age of 18 years that received an adenotonsillectomy for OSA and a preoperative and postoperative polysomnogram. Children with craniofacial or neuromuscular disorders or a tracheostomy were excluded. The primary outcome was the postoperative persistence of OSA, defined as a postoperative obstructive apnea-hypopnea index (oAHI) ≥ 1.5 events/hour. REM-predominant OSA was defined as a ratio of REM/NREM AHI ≥ 2. REM AHI minus NREM AHI and REM AHI minus oAHI helped to identify patients with a larger distribution of REM AHI. RESULTS A total of 353 patients were included. Postoperative persistent OSA was seen in 232 (65.7%) children. The preoperative REM AHI, REM AHI minus NREM AHI, and REM AHI minus oAHI of children with persistent OSA did not differ significantly from children with resolution of OSA. Rates of persistence were not different between those with REM-predominant OSA and REM-independent OSA (63.8% vs 70.7%, P = .218). CONCLUSION This study suggests that preoperative REM AHI may be a poor predictor of OSA persistence after adenotonsillectomy. Further study is needed to help characterize how pre-operative REM AHI should impact clinicians' decision making, family counseling and recommendations.

Abstract
BACKGROUND The conventional measure of sleep fragmentation is via polysomnographic evaluation of sleep architecture. Adults with OSA have disruption in their sleep cycles and spend less time in deep sleep stages. However, there is no available evidence to suggest that this is also true for children and published results have been inconclusive. OBJECTIVE To determine polysomnographic characteristics of sleep architecture in children with OSA and investigate effects relative to OSA severity. METHODS Overnight polysomnograms (PSG) of children referred for suspected OSA were reviewed. Subjects were classified by apnea hypopnea index (AHI). PSG parameters of sleep architecture were recorded and analyzed according to OSA severity. RESULTS Two hundred and eleven children were studied (median age of 7.0 years, range 4-10 years) Stage N1 sleep was longer while stage N2 sleep and REM sleep was reduced in the OSA group when compared to those without OSA (6.10 vs 2.9, P < .001; 42.0 vs 49.7, P < .001; 14.0 vs 15.9, P = .05). The arousal index was also higher in the OSA group (12.9 vs 8.2, P < .001). There was a reduction in sleep efficiency and total sleep time and an increase in wake after sleep onset noted in the OSA group (83.90 vs 89.40, P = .003; 368.50 vs 387.25, P = .001; 40.1 ± 35.59 vs 28.66 ± 24.14, P = .007; 29.00 vs 20.50; P = .011). No significant difference was found in N3 sleep stage (33.60 vs 30.60, P = .14). CONCLUSION We found evidence that children with OSA have a disturbance in their sleep architecture. The changes indicate greater sleep fragmentation and more time spent in lighter stages of sleep. Future research is needed and should focus on more effective methods to measure alterations in sleep architecture.

Changes in behavioral and cognitive abilities after rapid maxillary expansion in children affected by persistent snoring after long-term adenotonsillectomy: A noncontrolled study. Am J Orthod Dentofacial Orthop 2024; 165:344-356.

Abstract
INTRODUCTION The objective of this study was to verify changes in behavioral abilities and cognitive functions after rapid maxillary expansion (RME) in children with refractory sleep-disordered breathing (SDB) in the long term after adenotonsillectomy. METHODS A prospective clinical trial study using RME therapy was conducted. Participant inclusion criteria were children who had adenotonsillectomy with maxillary transverse deficiency and persistent SDB (obstructive apnea-hypopnea index ≥1). The study included 24 children aged 5-12 years, and of these 24 children, 13 had primary snoring and 11 had obstructive sleep apnea. The patients underwent laryngeal nasofibroscopy and a complete polysomnography. In addition, patients completed the Obstructive Pediatric Sleep Questionnaire and Obstructive Sleep Apnea 18-Item Quality-of-Life Questionnaire. Behavioral and neurocognitive tests were also completed before and after RME. RESULTS The Obstructive Pediatric Sleep Questionnaire and Obstructive Sleep Apnea 18-Item Quality-of-Life scores showed a statistically significant decrease in both groups (P <0.001) after RME. The results showed that neurocognitive and behavioral parameters (Child Behavior Checklist scale) were similar in primary snoring and obstructive sleep apnea (OSA) groups before RME. In the OSA group, the mean scores of the "Somatic" and "Aggressiveness" domains decreased significantly (P <0.05). The cognitive functions did not register significant differences pre- and post-RME in any of the cognitive functions, except for visuospatial function in the OSA group. CONCLUSIONS The noncontrolled design was a major limitation of our study. The need for treatment for SDB should consider the association of symptoms and behavioral disturbances with the child's obstructive apnea-hypopnea index. RME might prove to be an alternative treatment for children with SDB refractory to adenotonsillectomy, improving quality of life and behavioral aspects. However, a larger sample size with a control group is needed to substantiate these claims.

Abstract
STUDY OBJECTIVES Prior studies have demonstrated the efficacy of lingual tonsillectomy in treating pediatric obstructive sleep apnea. The goal of this study is to describe the postoperative outcomes following lingual tonsillectomy as a part of drug-induced sleep endoscopy-directed multilevel sleep surgery. METHODS A retrospective review was performed for pediatric patients with obstructive sleep apnea who underwent lingual tonsillectomy as a part of drug-induced sleep endoscopy-directed sleep surgery. Data collected included age, sex assigned at birth, body mass index z-score, polysomnography results, past medical and surgical history, and postoperative outcomes. RESULTS A total of 174 patients were included in the study with a mean age of 8.29 ± 3.49 years (range 1.89-15.62) and mean preoperative apnea-hypopnea index of 7.88 ± 13.42 (range 1.10-123.40). Complications occurred in 26 patients (14.9%) including 14 patients (8.0%) requiring emergency department visit or readmission and 12 patients (6.9%) experiencing postoperative bleeding. Asthma (P = .033) and developmental delay (P = .016) correlated with postoperative complications. For patients with preoperative and postoperative polysomnography data (n = 145; 83.3%), there was significant improvement (P < .001) in apnea-hypopnea index with a mean postoperative apnea-hypopnea index of 4.02 ± 7.81 (range 0.00-54.46). Surgical failure, defined as postoperative apnea-hypopnea index ≥ 5, was identified in 25 patients (17.2%). Surgical failure was associated with body mass index z-score > 2 (P = .025) and Trisomy 21 (P = .005). CONCLUSIONS This study highlights the promising surgical success rate of drug-induced sleep endoscopy-directed lingual tonsillectomy in multilevel sleep surgery (82.8%) and infrequent complications including postoperative bleeding (6.9%) and readmission (2.3%).

Abstract
Background Obstructive sleep apnea (OSA) is a type of sleep-disordered breathing disease, with high prevalence and multiple complications. It seriously affects patients' quality of life and even threatens their lives. Early and effective treatment can significantly improve patients' health conditions. Objective In this study, the main treatment methods, research hotspots and trends of OSA were summarized through bibliometric and visualization analysis. Methods From the Web of Science Core Collection database, articles on the treatment of OSA from 1999 to 2022 were obtained. CiteSpace and VOSviewer were comprehensively used to visualization of journals, co-authorship of countries, institutions and authors, co-citation of references, keywords cluster and burst. Results A total of 2,874 publications were obtained, of which 2,584 were concerned adults and 290 about children. In adults' research, Sleep and Breathing is the most published journal (280, 10.84%), the largest number of publications come from the United States (636,24.61%) and the University of Sydney (88, 3.41%), and Pepin JL is the most published author (48, 18.58%). In children's studies, International Journal of Pediatric Otorhinolaryngology is the most published journal (41, 14.14%), the maximum number of publications were also from the United States (123, 42.41%), with the University of Pennsylvania (20, 6.90%) and Marcus CL (15, 5.17%) being the most published institutions and authors. High-frequency keywords for adults' researches include positive airway pressure, oral appliance, surgery and positional therapy. On these basis, children's studies also focus on myofunctional therapy, rapid maxillary expansion and hypoglossal nerve Stimulation. Conclusion Over the past two decades, research in the field of OSA therapeutics has experienced significant growth in depth and breadth. The author cooperation network has already established a solid foundation, while there is potential for further strengthening the cooperation network between countries and institutions. Currently, positive airway pressure and surgery are the primary treatments for OSA in adults and children. Future research will focus on multidisciplinary combination targeted therapy, which presents a key area of interest and challenge.

Fageeh YA. Clinical Impact of Preoperative Tonsil and Adenoid Size on Symptomatic Outcomes Following Adenotonsillectomy in Pediatric Patients. Cureus 2023; 15:e47093. [PMID: 38021551 PMCID: PMC10646436 DOI: 10.7759/cureus.47093] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 10/16/2023] [Indexed: 12/01/2023] Open
Abstract
Background Adenotonsillar hypertrophy is a common clinical problem in pediatric patients. Adenotonsillectomy is a surgical intervention to remove airway obstruction and alleviate symptoms. However, some children continue to experience persistent symptoms after surgery. Objective This study aimed to investigate the relationship between preoperative tonsils and adenoid size and the persistence of symptoms, including snoring, mouth breathing, noisy breathing, and sleep apnea, after adenotonsillectomy in pediatric patients. Method This study was conducted in Taif, Saudi Arabia, and included 109 pediatric patients aged three to 14 years who underwent adenotonsillectomy. Data on preoperative and postoperative symptoms were collected through patient records and follow-up surveys. Tonsil and adenoid size were assessed using the Brodsky scale and endoscopic grading scales, respectively. Statistical analysis was performed using SPSS Version 26 (IBM Corp., Armonk, NY). Results The most prevalent presenting symptoms were snoring, mouth breathing, and noisy breathing. Tonsil size grades 3+ and 4+ were significantly more prevalent than the other grades (p<0.05). Adenoid size grades 3 and 4 were also significantly more prevalent than the other grades (p<0.05). Significant associations were observed between tonsil and adenoid size grades and specific presenting symptoms, such as snoring, mouth breathing, and noisy breathing. No significant correlations were found between preoperative tonsil or adenoid size and postoperative persistent symptoms. Conclusion While tonsil and adenoid size are essential factors in determining the need for surgery, they may not predict postoperative resolution of symptoms. A comprehensive evaluation of various clinical factors is necessary to understand the persistence of symptoms after surgery. Although adenotonsillectomy is an effective treatment for upper airway obstruction in pediatric patients, some individuals may experience residual symptoms.

Abstract
Hyperplasia of the pharyngeal tonsils is to be considered pathologic when nasopharyngeal symptoms of mechanical obstruction and/or chronic inflammation occur. Chronic Eustachian tube dysfunction can result in various middle ear diseases such as conductive hearing loss, cholesteatoma, and recurrent acute otitis media. During examination, attention should be paid to the presence of adenoid facies (long face syndrome), with a permanently open mouth and visible tip of the tongue. In the case of severe symptoms and/or failure of conservative treatment, adenoidectomy is usually performed on an outpatient basis. Conventional curettage remains the established standard treatment in Germany. Histologic evaluation is indicated for clinical evidence of mucopolysaccharidoses. Due to the risk of hemorrhage, the preoperative bleeding questionnaire, which is obligatory before every pediatric surgery, is referred to. Recurrence of adenoids is possible despite correct adenoidectomy. Before discharge home, otorhinolaryngologic inspection of the nasopharynx for secondary bleeding should be performed and anesthesiologic clearance obtained.

Abstract
Background Dietary behavior is a main contributing yet modifiable factor to the body weight status of children and may be involved in the pathophysiology of childhood obstructive sleep apnea (OSA). This study aimed to investigate the dietary profile of pediatric OSA patients, effects of educational counseling after adenotonsillectomy, and predictor for disease resolution. Methods This observational study included 50 pediatric OSA patients undergoing adenotonsillectomy with routine educational counseling (Group 1), 50 pediatric OSA patients undergoing adenotonsillectomy without formal educational counseling (Group 2), and 303 healthy children without OSA (Control). The three groups were matched by age. The consumption frequency of 25 food items/groups was assessed by the Short Food Frequency Questionnaire. Quality of life was evaluated by the OSA-18 questionnaire. Sleep architecture and OSA severity were measured by standard polysomnography. Between- and within-group comparisons were analyzed by non-parametric approaches and generalized estimating equations. Prediction of disease recovery was performed by multivariable logistic regression models. Results Group 1 children consumed fruit drinks with sugar, vegetables, sweets, chocolate, rice, and noodles more frequently than Control Group children. At baseline, the distributions of sex, weight status, OSA-18 scores, and polysomnographic variables were comparable between Group 1 and Group 2. After a 12-month follow-up, Group 1 had better improvements in physical suffering, caregiver concerns, sleep architecture, and mean peripheral oxygen saturation compared to Group 2. Furthermore, Group 1 no longer had excessive consumption of fruit drinks with sugar, chocolate, and noodles; however, food consumption frequencies did not change significantly. Notably, younger age and reduced intake of butter/margarine on bread and noodles were independent predictors of cured OSA in Group 1. Conclusion The present study preliminarily characterized an unhealthy dietary profile among pediatric OSA patients and suggested that routine educational counseling in addition to adenotonsillectomy yielded some clinical benefits. Certain items/groups of food frequencies may be associated with disease recovery and further investigations are warranted.

Abstract
OBJECTIVE To assess the short-term outcome of rapid maxillary expansion (RME) on periodic limb movement disorder (PLMD) in children with residual snoring after late adenotonsillectomy (AT). METHODS This prospective clinical trial included 24 patients treated with rapid maxillary expansion (RME). Participants' inclusion criteria were children with maxillary constriction aged 5-12 years who had AT for more than two years and those whose parents/guardians reported that they still snored ≥4 nights per week. Of which 13 had primary snoring, and 11 had OSA. All patients underwent laryngeal nasofibroscopy evaluation and complete polysomnography. The Quality of life (QOL) Questionnaire (OSA-18), the Pediatric Sleep Questionnaire (PSQ), the Conners Abbreviated Scale (CAE), and the Epworth Sleep Scale (ESS) were applied before and after palatal expansion. RESULTS The OSA 18 domain, PSQ total, CAE, and ESS scores were significantly reduced in both groups (p < 0.001). There was a decrease in PLMS indices. In the total sample, the mean decreased significantly from 4.15 to 1.08. In the Primary Snoring group, the mean decreased from 2.64 to 0.99; in the OSA group, the average decreased significantly from 5.95 to 1.19. CONCLUSION This preliminary study suggests that the improvement of PLMS in the OSA group with maxillary constriction is correlated with a favorable neurological impact of the treatment. We suggest a multi-professional approach to the treatment of sleep disorders in children.

Abstract
STUDY OBJECTIVES (1) To assess adenotonsillectomy (AT) outcomes in adolescents with obesity and with obstructive sleep apnea (OSA); (2) To identify clinical factors predicting OSA in adolescents following AT. METHODS Adolescents 12 to 18 years old with obesity who underwent AT for OSA were included. Subjects had pre-AT and post-AT polysomnogram. Nonobese adolescents with OSA that underwent AT were included as a comparison. RESULTS Seventy adolescents with obesity with a mean age of 14.2 years and a mean body mass index of 38.0 kg/m2 were included. Patients in the nonobese group (n = 32) were similar demographically to the obese group, with the exception of body mass index. The majority of adolescents with obesity (74%) had severe OSA (apnea-hypopnea index [AHI] ≥ 10 events/h) with a mean baseline AHI of 33.9 events/h (standard deviation 28.5). The obese and control groups experienced clinically meaningful improvements in AHI following AT, with median change scores of 18.3 (95% confidence interval -29.2, -11.2, P < .001) and 14.6 (95% confidence interval -25.5, -8.5, P < .001), respectively. In the adolescents with obesity, 48% had an AHI < 5 events/h on postoperative PSG. However, adolescents with obesity were 7 times more likely (odds ratio = 7.1, 95% confidence interval [2.24, 22.48], P = .001) to have moderate or severe persistent OSA (AHI > 5 events/h) after AT compared with patients who were not obese. The need for post-AT positive airway pressure therapy was significantly higher in adolescents with obesity, with 37.1% of participants requiring this therapy (odds ratio = 8.3, 95% confidence interval 1.8, 37.6, P < .001). CONCLUSIONS AT results in improvement in polysomnogram parameters in adolescents with obesity and OSA. However, patients with obesity are at high risk for persistent OSA. Future research should include prospective trials to compare outcomes between AT and positive airway pressure therapy for adolescents with obesity. CITATION Kearney TC, Vazifedan T, Baldassari CM.

Abstract
OBJECTIVE To investigate the influence of adenotonsillectomy (T&A) on ambulatory blood pressure (BP) variability in children with obstructive sleep apnea (OSA). STUDY DESIGN Prospective, interventional study. METHODS Children with OSA symptoms were recruited from a tertiary center. After OSA diagnosis was confirmed (ie, apnea-hypopnea index [AHI] > 1), these children underwent T&A for treatment. We performed polysomnography and 24-hour recordings of ambulatory BP before and 3 to 6 months postoperatively. Ambulatory BP variability was presented as the standard deviation of mean blood pressure in the 24-hour monitoring of ambulatory BP. Differences in BP variability among different subgroups were tested using a multivariable linear mixed model. RESULTS A total of 190 children were enrolled (mean age: 7.8 ± 3.3 years; 73% were boys; 34% were obese). The AHI significantly decreased from 12.3 ± 17.0 to 2.7 ± 5.5 events/hr after T&A. Overall, daytime, and nighttime ambulatory BP did not significantly change postoperatively, and overall, daytime, and nighttime ambulatory BP variability did not differ significantly preoperatively and postoperatively. In the subgroup analysis, children aged <6 years demonstrated a significantly greater decrease in ambulatory BP variability postoperatively than those aged >6 years (nighttime diastolic BP variability: 9.9 to 7.7 vs. 8.9 to 9.4). Children with hypertension also showed a significantly greater decrease in ambulatory BP variability than those without hypertension. CONCLUSIONS We concluded that overall ambulatory BP variability does not significantly change after T&A in children with OSA. Moreover, young-aged and hypertensive children demonstrate a significant decrease in BP variability after T&A. LEVEL OF EVIDENCE 4 Laryngoscope, 132:2491-2497, 2022.

Abstract
Available information on clinical characteristics and post-operative outcomes in children with very severe obstructive sleep apnea (OSA) is limited. Our study evaluates the clinical features and polysomnographic (PSG) variables that predict post-operative outcomes in children with an obstructive apneal hypopnea index (AHI) of more than 25 events/hr. In this study from a single tertiary care center, we performed a retrospective chart review of patients with an AHI > 25/hr, who underwent tonsillectomy and adenoidectomy (T&A) between January 2016 and September 2021. In total, 50 children were included in the study: 26.0% (13/50) of children experienced post-operative respiratory events and four children needed intubation and ventilator support. Compared with children without respiratory events, children requiring post-operative respiratory interventions were younger (4.4 ± 5.2 vs. 8.0 ± 5.2 years; p = 0.04), had higher pre-operative AHI (73.6 ± 27.4 vs. 44.8 ± 24.9; p < 0.01), lower oxygen nadirs (70.0 ± 13.0% vs. 83.0 ± 7.0%; p < 0.01), and had lower body metabolic index Z-scores (−0.51 ± 2.1 vs. 0.66 ± 1.5; p < 0.04). Moderate to severe residual OSA was identified in 70% (24/34) of children with available post-operative PSG; younger children had better PSG outcomes. Our study shows that post-operative respiratory events are frequent in children with very severe OSA, particularly with an AHI > 40/h, younger children (<2 years of age), lower oxygen saturation (SpO2), and poor nutritional status, necessitating close monitoring.

Abstract
OBJECTIVE To address positive airway pressure (PAP) adherence in adolescents diagnosed with obstructive sleep apnoea (OSA) by pilot testing a novel, online, facilitated, peer-support and health education programme for families. DESIGN SETTING AND METHODS Families participated in separate Facebook peer-groups (adolescent [n=6] and parent [n=6]) for four weeks, followed by face-to-face interviews. Participants received OSA and PAP educational videos and posts, engaged with questions and polls, and viewed de-identified postings of peer PAP use data. RESULTS Adolescent participants were young Black males aged 13-17 years (n=6) with obesity (n=5), severe sleep apnoea (100%) and 4-15 months of prior PAP use. Parent participants were mothers (n=4) and fathers (n=2). Four of six young males increased their mean PAP use during the intervention period. Overall, parents were more engaged with the Facebook group page than adolescents, but interviews revealed the online group/peer-support and education provided was highly regarded and appreciated by families. Parents were particularly appreciative of being involved in care and diagnosis in this way. CONCLUSION Results of this pilot trial provide important data regarding intervention design, content, and delivery approaches to be considered in the development of future interventions aiming to engage families and improve adolescent PAP adherence.

Abstract
OBJECTIVE To investigate the relative contributions of obesity and obstructive sleep apnea (OSA) to unfavorable blood pressure in children. STUDY DESIGN Children aged 3-18 years with OSA-related symptoms were recruited. All children underwent office blood pressure (BP) monitoring and full-night polysomnography. Obesity was defined as a body mass index ≥95th percentile. OSA severity was divided into primary snoring (apnea-hypopnea index [AHI] <1), mild OSA (5> AHI ≥1), and moderate to severe OSA (AHI ≥5). Age- and sex-adjusted logistic regression analysis was performed to determine the associations among OSA, obesity, and elevated BP. RESULTS This cross-sectional study enrolled 1689 children (66% boys), with a mean age of 7.9 years. Compared with children with primary snoring, children with moderate to severe OSA had significantly higher systolic BP (108.1 mmHg vs 105.6 mmHg), diastolic BP (75.0 mmHg vs 70.4 mmHg), systolic BP percentile (75.0 vs 70.4), and diastolic BP percentile (74.0 vs 69.2). The rate of unfavorable BP (ie, elevated BP or hypertension level BP) also was significantly higher in children with more severe OSA. Children with obesity had higher BP and BP percentile. Logistic regression analysis revealed that children with obesity and moderate to severe OSA have a 3-fold greater risk of unfavorable BP compared with children without obesity and primary snoring. CONCLUSIONS We identified a 3-fold greater risk of unfavorable BP in children with obesity and moderate to severe OSA.

Abstract
BACKGROUND Lateral parapharyngeal wall (LPW) thickness is a potentially useful anatomical marker of childhood obstructive sleep apnea (OSA). Measuring LPW thickness by ultrasonography (USG) is technically feasible but its use in children has not been validated. Therefore, this study aimed to assess the intra- and inter-operator reliability of the sonographic measurements of LPW thickness in children and to assess its validity against magnetic resonance imaging (MRI) measurements. METHODS Prepubertal children aged 6-11 years suspected to suffer from OSA were recruited. Repeated measurements of LPW thickness by USG were conducted to evaluate the intra- and inter-operator reliability, examined by intraclass correlation coefficient (ICC). LPW thickness was measured as the distance between the internal carotid artery and the echogenic surface of the pharynx in an oblique coronal plane by USG. LPW thickness was measured by MRI at the retropalatal level. The agreement between the LPW thickness measured by USG and MRI was assessed by ICC and Bland-Altman plot. RESULTS Thirty-four children (mean age: 8.66 ± 1.61, 26 male) were recruited. The intra- and inter-operator reliability of the LPW thickness by USG was good (ICC = 0.84 and 0.82, respectively). The agreement between the USG-measured and MRI-measured LPW thickness was moderate (ICC = 0.72). he Bland-Altman plot demonstrated a mean difference of 0.061 cm and a 95% limit of agreement from 0.91 to 1.12 cm. CONCLUSION In this study, we demonstrated that ultrasonography is a valid and reliable method to assess LPW thickness in children. This study was supported by the Direct Grant for Research from the Research Committee of the Chinese University of Hong Kong (Project no. 2020.073).

Abstract
OBJECTIVES To determine predictors of obstructive sleep apnea (OSA) in underweight children and to describe the demographic, clinical, and polysomnographic characteristics of an ethnically diverse population of underweight children with OSA. STUDY DESIGN Case-control study. SETTING University of Texas Southwestern Medical Center and Children's Medical Center of Dallas. METHODS Underweight children aged 2 to 18 years who underwent a polysomnogram for suspected OSA between January 2014 and December 2020 were included. Underweight was defined as body mass index <5th percentile per Centers for Disease Control and Prevention guidelines. Children with apnea-hypopnea index <1.0 served as a control group. Univariate and multiple logistic regression analysis was used to determine the predictors of OSA. Significance was set at P < .05. RESULTS An overall 124 children met inclusion criteria: mean age, 6.4 years; 50% female; 44% Hispanic, 31% African American, and 18% Caucasian. A total of 83 children had OSA (apnea-hypopnea index ≥1.0). Height was negatively correlated with OSA (odds ratio, 0.94; 95% CI, 0.88-0.99; P = .02) while allergic rhinitis (odds ratio, 2.97; 95% CI, 1.24-7.08; P = .01) and tonsillar hypertrophy (odds ratio, 3.38; 95% CI, 1.42-8.02; P = .01) were predictors for the presence of OSA. No demographic or clinical characteristics were predictors for severe OSA. CONCLUSION Underweight children with OSA, as compared with those without OSA, are more likely to have decreased height, tonsillar hypertrophy, and allergic rhinitis. There are no predictors of severe OSA in underweight children. We recommend polysomnography for the diagnosis of OSA in symptomatic underweight children with large tonsils, especially when they have a history of allergies.

Abstract
The obstructive sleep apnoea syndrome (OSAS) affects 1-4% of adolescents. It represents a transitional stage between paediatric and adult OSA and is characterized by specific symptoms. BACKGROUND: The persistence of childhood OSAS during adolescence is not frequent. Risk factors are male sex, obesity and a history of tonsillectomy or adenoidectomy. Symptoms may be misleading such as tiredness and depressive disorders. In adolescence, untreated OSAS may result in neuro-behavioural and cognitive deficits, systemic inflammation, cardiovascular and metabolic disorders. The French Society of Research and Sleep Medicine organized a meeting on OSAS in adolescents. A multidisciplinary group of specialists (pulmonologists, pediatricians, ENT and maxillo-facial surgeons, dentofacial orthopedists/orthodontists, myofunctional therapists and sleep specialists) exchanged their experience, discussed publications and drew up a consensus document on the diagnosis and polysomnographic criteria for OSAS in adolescents. They proposed a practical diagnostic guideline and follow-up for these adolescents. OUTLOOK AND CONCLUSION: A good knowledge of the particularities of this pathology by the physician will lead to an early diagnosis, propose adapted multifactorial treatments and avoid the deleterious consequences of this pathology at adult age.

Abstract
BACKGROUND There is a critical gap in identifying effective interventions for children with obstructive sleep apnea (OSA) who do not tolerate continuous positive airway pressure therapy. Positional OSA (POSA) is a common clinical phenotype whereby OSA occurs predominantly while sleeping in supine position. POSA may be amenable to treatment with a positional device, a belt worn around the chest with cushions on the back to prevent supine positioning, but no data exists in children. The primary aim of this study was to evaluate the efficacy of positional device therapy for the treatment of POSA in children. METHODS This observational study included children aged 4-18 years with POSA and an obstructive apnea-hypopnea index (OAHI) ≥ 5 events/hour on baseline polysomnogram (PSG) who underwent a second PSG to evaluate the efficacy of a positional device. The primary outcome was the change in OAHI. RESULTS Ten children were included (8 male, median age 11.2 years, median body mass index z-score 1.6). Compared to the baseline PSG, PSG data obtained while using a positional device showed a reduced median (interquartile range) OAHI (15.2 [8.3-25.6] versus 6.7 [1.0-13.7] events/hour respectively; p = 0.004) and percentage of total sleep time in supine position (54.4 [35.0-80.6]% versus 4.2 [1.1-25.2]% respectively; p = 0.04). Despite observed improvements in the oxygen desaturation index, these results were not statistically significant. SIGNIFICANCE AND CONCLUSIONS In this novel pilot study, positional device therapy was effective for the treatment of POSA. Positional device therapy may potentially change clinical practice as a cost-efficient and non-invasive treatment option for POSA.

Abstract
OBJECTIVE C-reactive protein (CRP) is an important serum marker of inflammation associated with cardiovascular outcomes. This study aims to evaluate the association between CRP and childhood obstructive sleep apnea (OSA) and clarify the effects of adenotonsillectomy on serum CRP levels in children with OSA. METHODS Children with symptoms suggestive of OSA who underwent an overnight polysomnography were recruited from a tertiary medical center. Their serum CRP levels were measured. For children who underwent adenotonsillectomy for OSA treatment, polysomnography and serum high-sensitivity CRP (hs-CRP) level measurement were conducted after surgery. RESULTS This study included 326 children (mean age: 7.2 ± 3.0 years; boys: 67%). Children with apnea-hypopnea index (AHI) > 5 events/h had significantly higher hs-CRP levels than children with AHI of 1-5 events/h and AHI < 1 event/h [median (interquartile range): 0.08 (0.03-0.25) vs 0.03 (0.02-0.14) vs 0.04 (0.01-0.10), P < 0.001]. Log-transformed hs-CRP levels were positively associated with log AHI values (r = 0.2, P < 0.001). In multiple linear regression analysis, hs-CRP levels were independently associated with AHI; 101 children with OSA (ie, AHI > 1) underwent adenotonsillectomy. In children with OSA in the study cohort, a significant reduction of hs-CRP levels did not occur after surgery [from 0.07 (0.02-0.22) to 0.08 (0.03-0.17), P = 0.716]. In children with OSA having abnormal hs-CRP levels (ie, CRP > 1 mg/dL), hs-CRP levels significantly decreased after surgery [from 1.87 (1.11-2.78) to 0.20 (0.07-1.04), P = 0.043]. CONCLUSION Children with OSA had increased hs-CRP levels. Children with OSA and abnormal hs-CRP levels exhibited significantly reduced hs-CRP levels following adenotonsillectomy.

Abstract
STUDY OBJECTIVES Increased neck circumference, a surrogate for the neck fat that can narrow the upper airway in obese individuals, is a risk factor for obstructive sleep apnea syndrome (OSAS) in adults, but the association between neck fat and OSAS in adolescent males and females is unknown. We hypothesized that obese adolescents with OSAS have more neck fat than controls, females more neck fat than males, and that neck fat correlates with obesity and OSAS severity. METHODS Obese adolescents with OSAS and obese and normal-weight controls underwent upper airway magnetic resonance imaging, polysomnography, and anthropometrics, including neck circumference measurement. Intra-neck and subcutaneous neck fat measurements were manually segmented and compared among the three groups using ANOVA and between males and females using t-tests. The relationship between polysomnographic parameters and neck fat measurements was assessed in adolescents with OSAS using Pearson correlations. RESULTS One-hundred nineteen adolescents (38 females) were studied: 39 obese with OSAS, 34 obese controls, and 46 normal-weight controls. Neck fat was not greater in adolescents with OSAS compared to obese controls (p=0.35), and neck fat volume was not related to OSAS severity (p=0.36). However, obese adolescents had more neck fat than normal-weight controls (p<0.001), and neck fat volume correlated with neck circumference (r=0.53, p<0.001). Females had significantly greater cross-sectional neck fat than males (p<0.001). CONCLUSIONS While neck fat is associated with obesity and neck circumference in adolescents and is greater in females versus males, it does not appear to correlate with presence and severity of OSAS.

Abstract
BACKGROUND While adenotonsillectomy (T&A) is widely recognized as the first-line therapy for pediatric obstructive sleep apnea (OSA), effects of T&A on blood pressure (BP) remain unclear. This meta-analysis evaluates the associations between T&A and BP in children with OSA. METHODS The study protocol was registered on PROSPERO (CRD42020154425). Two authors independently searched the PubMed, Medline, EMBASE, and Cochrane databases. The keywords used were "sleep apnea syndromes," "adenotonsillectomy," and "child." A random-effects model was applied to determine office systolic BP (SBP), diastolic BP (DBP), and ambulatory BP changes. RESULT Twelve studies with 1193 children were analyzed (mean age: 7.6 y; 54% boys). The apnea-hypopnea index significantly reduced of 9.4 events/h (95% CI, -12.0 to -6.8) after T&A. Office SBP (-0.24 mmHg; 95% CI, -1.64 to 1.16) and DBP (-1.65 mmHg; 95% CI, -3.47 to 0.17) did not decrease significantly after surgery. No significant decreases were observed in 24-h ambulatory BP after T&A. Subgroup analysis showed a significant postoperative decrease in office SBP (-6.23 mmHg; 95% CI, -7.78 to -4.67) and DBP (-7.93 mmHg; 95% CI, -10.37 to -5.48) among children with hypertension but a slight increase in office SBP (2.50 mmHg; 95% CI, 1.14 to 3.86) and DBP (1.98 mmHg; 95% CI, -0.02 to 3.98) in those without (P for heterogeneity < 0.001). CONCLUSION This meta-analysis suggests the office and ambulatory BP changes after T&A in children with OSA are trivial. Moreover, children with hypertension experience a significantly greater decrease in office BP than children without hypertension.

Abstract
Nasorespiratory obstruction has been purported to influence dentofacial growth adversely. This has sparked considerable debate for decades with a resurgence in interest in 'airway friendly orthodontics' among both general and specialist dental practitioners. This critical review aims to evaluate the current literature relating to two questions: does nasorespiratory obstruction alter dentofacial growth, and does early intervention targeted at alleviating nasorespiratory obstruction improve dentofacial growth? The strength of association between nasorespiratory obstruction, mouth breathing and a long face is weak. The common methodological flaws in research include unblinded and cross-sectional study designs, a lack of adequate controls, inadequate follow-up, subjective assessments and inadequate statistical power. Vertical dentofacial growth has a strong genetic influence, which implies a relatively minor contribution of environmental factors including airway obstruction. The current evidence does not support recommending procedures, such as adenotonsillectomy and maxillary expansion, with the singular aim of negating a hyperdivergent (vertical) dentofacial growth pattern. In light of low-quality evidence, both the World Health Organization guidelines and ethical principles dictate that greater emphasis is placed on avoiding harm and wastage of resources over alternative options. These findings call for quality improvement in undergraduate and postgraduate curricula and continuing professional development for health professionals.

Abstract
INTRODUCTION Obstructive sleep apnea is a frequent entity in childhood that can lead to important consequences for the health and children's quality of live. Polysomnography is the gold-standard exam to diagnose obstructive sleep apnea, but it is expensive, complex, and poorly affordable in Brazil. The pediatric sleep questionnaire has shown to be a valuable screening test for obstructive sleep apnea. It is a simple questionnaire with good sensitivity and specificity compared to polysomnography in the countries where it has been validated. OBJECTIVE Translation and cross-cultural adaptation of the pediatric sleep questionnaire (PSQ), into Brazilian Portuguese. METHODS The translation of the PSQ into Brazilian Portuguese was carried out in accordance with good practices. The validated and adapted questionnaire was applied to parents/caregivers of 60 children (40 of them with obstructive sleep apnea and 20 controls) aged 2-18 years. Retest was applied to 30 children with obstructive sleep apnea. The following tests were performed: internal consistency, test-retest, validation of questionnaire (the latter by ROC curve). RESULTS Brazilian PSQ has shown high internal consistency by Cronbach's alpha (0.86 for the total test, 0.83 for subscale "snoring", 0.64 for "sleepiness" and 0.65 for "behavior"). Test-retest presented a correlation of 0.89 for subscale "snoring", 0.93 for "sleepiness" and 0.86 for "behavior". Accuracy by ROC curve was 0.99. Nine was considered the optimal value to discriminate patients with obstructive sleep apnea from controls, with a sensitivity of 0.92 and specificity of 1.0. CONCLUSION The translation and cross-cultural adaptation of the PSQ into Brazilian Portuguese proved to be successful. In places with difficult access to polysomnography, PSQ can be a useful tool in screening and follow-up of children with obstructive sleep apnea.

Obstructive sleep apnoea syndrome (OSAS) is defined as the intermittent reduction or cessation of airflow due to partial or complete obstruction of the upper airway during sleep. Paediatric OSAS has specific contributing factors, presenting symptoms and management strategies in various age groups. Untreated OSAS can lead to detrimental effects on neurocognitive development and cardiovascular and metabolic functions of a growing child. In the past decade, practice guidelines have been developed to guide the evaluation and management of OSAS. This article provides a narrative review on the current diagnostic and treatment options for paediatric OSAS. Alternative diagnostic tools other than the standard polysomnography are discussed. Adenotonsillectomy is considered the first-line therapy yet it is not suitable for treatment of all OSAS cases. Nocturnal non-invasive positive airway pressure ventilation is effective and could be the priority treatment for patients with complex comorbidities, residual OSAS post-adenotonsillectomy or obesity. However, intolerance and non-adherence are major challenges of positive airway pressure therapy especially in young children. There is increasing evidence for watchful waiting and other gentler alternative treatment options in mild OSAS. The role of anti-inflammatory drugs as the primary or adjunctive treatment is discussed. Other treatment options, including weight reduction, orthodontic procedures and myofunctional therapy, are indicated for selected patients. Nevertheless, the successful management of paediatric OSAS often requires a multidisciplinary team approach.

Abstract
Importance Adenotonsillectomy (ATE) is one of the most common surgical procedures to treat children with obstructive sleep apnea (OSA), but to our knowledge there are no randomized clinical trials confirming the benefit of surgery compared with watchful waiting in children between 2 and 4 years of age. Objective To determine whether ATE is more effective than watchful waiting for treating otherwise healthy children with mild to moderate OSA. Design, Setting, and Participants This randomized clinical trial was conducted from December 2014 to December 2017 at the Otorhinolaryngology Department of the Karolinska University Hospital, Stockholm, Sweden. A total of 60 children, 2 to 4 years of age, with an obstructive apnea-hypopnea index (OAHI) score of 2 or greater and less than 10, were randomized to ATE (n = 29) or watchful waiting (n = 31). A total of 53 participants (88%; ATE, n = 25; watchful waiting, n = 28) completed the study. Data were analyzed from August 2018 to December 2018. Interventions Adenotonsillectomy. Main Outcomes and Measures The primary outcome was the difference between the groups in mean OAHI score change. Secondary outcomes were other polysomnography parameters, score on the Obstructive Sleep Apnea-18 (OSA-18) questionnaire, and subgroup analyses. Polysomnography and the OSA-18 questionnaire were completed at baseline and after 6 months. Results Of the 60 included children, 34 (57%) were boys and the mean (SD) age at first polysomnography was 38 (9) months. Both groups had a decrease in mean OAHI score, and the difference in mean OAHI score change between the groups was small (-1.0; 95% CI, -2.4 to 0.5), in favor of ATE. However, there were large differences between the groups in favor of ATE regarding the OSA-18 questionnaire (eg, total OSA-18 score: -17; 95% CI, -24 to -10). Also, a subgroup analysis of 24 children with moderate OSA (OAHI ≥5 and <10) showed a meaningful difference in mean OAHI score change between the groups in favor of ATE (-3.1; 95% CI, -5.7 to -0.5). Of 28 children, 10 (36%) in the watchful waiting group received ATE after the follow-up, and 7 of these had moderate OSA at baseline. Conclusions and Relevance This randomized clinical trial found only small differences between the groups regarding changes in OAHI, but further studies are needed. However, there were large improvements in quality of life after ATE. These results suggest that otherwise healthy children with mild OSA and mild effect on quality of life may benefit from watchful waiting, while children with moderate OSA should be considered for ATE.

Abstract
PURPOSE Hypertrophy of adenoid and tonsils is the most common risk factor for OSA in children, and adenotonsillectomy is considered the first-line treatment. The effect of surgery for OSA in children varies considerably between studies, and few studies have focused on the effect in young children under 5 years of age. Thus, the aim of this study was to: 1) evaluate the effect of surgery for OSA in young children using objective data from polysomnography and parent-reported symptoms using questionnaires, and 2) identify predictors of residual OSA following surgery. METHODS This is a prospective cohort study of children aged 2-4 years who were referred for surgery to treat OSA. Measures collected before and after surgery included polysomnography (PSG), Pediatric Sleep Questionnaire (PSQ), OSA-18 and clinical data. RESULTS 56 children completed a preoperative and postoperative PSG. Their median age was 3.1 (IQR 2.6-3.1) years. After surgery, 63% had an obstructive apnea hypopnea index (OAHI) < 1, 82% had an OAHI < 2 and 95% had an OAHI < 5. Parent-reported OSA-18 and PSQ scores improved significantly after surgery. In logistic regression analyses, higher preoperative OAHI was the only significant clinical predictor of residual OSA after surgery. CONCLUSION There was a high resolution rate after surgery for OSA in this group of young children, with significant improvements in both the OAHI measured with PSG and parent-reported symptoms. The only clinical predictor of residual OSA after surgery was higher preoperative OAHI.

Abstract
OBJECTIVE To evaluate blood pressure (BP) variability in 24-hour ambulatory BP monitoring in children with obstructive sleep apnea (OSA). STUDY DESIGN Case series study. METHODS Children aged 4 to 16 years with clinical symptoms were recruited in a tertiary medical center. Overnight polysomnography and 24-hour recordings of ambulatory BP were performed for each child. The severity of OSA was classified as primary snoring (apnea-hypopnea index [AHI] < 1), mild OSA (1 ≤ AHI < 5), moderate OSA (10 > AHI ≥ 5), and severe OSA (AHI ≥ 10). The standard deviation of mean BP was used as an indicator of BP variability. RESULTS A total of 550 children were included (mean age: 7.6 years; 70% were boys; 20% were obese). Compared with the children with primary snoring, children with severe OSA exhibited significantly higher nighttime systolic BP (108.0 vs. 100.5 mmHg, P < .001), nighttime diastolic BP (58.9 vs 55.6 mmHg, P = .002), nighttime mean arterial pressure (75.3 vs. 70.5 mmHg, P < .001), nighttime systolic BP load (40.5% vs. 25.0%, P < .001), nighttime diastolic BP load (25.3% vs. 12.9%, P < .001), and nighttime systolic BP variability (11.4 vs. 9.6, P = .001). Multiple linear regression analyses revealed an independent association between AHI and nighttime systolic BP variability (regression coefficient = 0.31, 95% CI = 0.06-0.56, P = .015) after adjustment for age, gender, adiposity, and hypertensive status. CONCLUSIONS OSA in children is associated with increased BP and BP variability. LEVEL OF EVIDENCE 4 Laryngoscope, 131:2126-2132, 2021.

Abstract
The purpose of this article is to provide a succinct summary of the sleep monitoring efforts that have been used in nocturnal enuresis (NE) and an overview of the knowledge that has accrued. This is not intended to be a comprehensive review, but rather is intended to highlight how polysomnography (PSG), a common sleep detection tool, has contributed to our understanding of NE, as arousal disorder is considered to be one of the important mechanisms. The authors have organized this report by analysis and display of different ingredients of PSG, starting with comparing the electroencephalogram (EEG) of controls and the enuretic children and then moving to evaluation of respiratory patterns of NE and comorbid disease obstructive sleep apnea (OSA). In addition, the authors' goal is to better understand the mechanism of NE by integrating various levels of sleep monitoring; those sleep-related clinical scale scores for NE are presented to date. Finally, we propose further research of NE to explore the microstructure alterations via PSG combined with EEG-fMRI or to use novel technology like portable device internet and deep learning strategy.

Effect of body weight on upper airway findings and treatment outcome in children with obstructive sleep apnea. Sleep Med 2020; 79:19-28. [PMID: 33465738 DOI: 10.1016/j.sleep.2020.12.028] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/26/2020] [Revised: 12/21/2020] [Accepted: 12/22/2020] [Indexed: 11/20/2022]
Abstract
OBJECTIVE/BACKGROUND Surgical interventions for obstructive sleep apnea (OSA) are less effective in obese than in normal-weight children. However, the mechanisms that underpin this relationship are not fully understood. Therefore, this study aimed to explore how body weight influences upper airway collapse and treatment outcome in children with OSA. METHODS We conducted a retrospective analysis of prospectively collected data on polysomnography, drug-induced sleep endoscopy (DISE), and treatment outcome in otherwise healthy children with OSA. Associations between body mass index (BMI) z-score and upper airway collapse during DISE were assessed using logistic regression modelling. Treatment success was defined as obstructive apnea-hypopnea index (oAHI) < 5 events/hour and cure as oAHI < 2 events/hour with obstructive apnea index < 1 event/hour. RESULTS A total of 139 children were included [median (Q1─Q3); age 4.5 (3.1─8.4) years; BMI z-score 0.3 (-0.8 to 1.4); oAHI 10.8 (6.8─18.0) events/hour]. Twenty-five of them were overweight and 21 were obese. After adjusting for age and history of upper airway surgery, BMI z-score was significantly correlated with circumferential upper airway collapse during DISE (odds ratio 1.67; 95% confidence interval 1.12─2.65; P = 0.011). Outcome of DISE-directed treatment was similar in normal-weight (success: 91.4%; cure: 78.5%), overweight (success: 88.0%; cure: 80.0%), and obese (success: 90.5%; cure: 76.5%) children. Children with circumferential collapse responded better to continuous positive airway pressure than to (adeno)tonsillectomy. CONCLUSION Increasing body weight is associated with circumferential upper airway collapse during DISE and, accordingly, may require treatment strategies other than (adeno)tonsillectomy.

Abstract
This systematic review assessed the prevalence of restless sleep in children, documented the association of restless sleep with other conditions, and summarized the existing evidence regarding whether restless sleep should be considered a distinct sleep disorder. A comprehensive search of electronic databases was performed using the broad search term "restless sleep" in all fields. Of the 266 articles retrieved, 107 were retained for inclusion in this review. The majority (n = 93) were observational studies. The studies were grouped under several pathologic/condition categories: sleep-disordered breathing (n = 19); adenotonsillectomy (n = 7); respiratory disorders, otitis media, and smoke exposure (n = 12); sleep-related movement disorders and restless sleep disorder (n = 11); neurologic or psychiatric disorders (n = 7); Down syndrome/other neurodevelopmental disorders (n = 10); sleep-related bruxism and other sleep disorders (n = 7); and restless sleep in the general population/mixed clinical samples (n = 18). A high prevalence of restless sleep was found in children with many of these underlying conditions, likely related to associated inherent sleep disruption and frequent awakenings (e.g., apnea and periodic limb movements), pain, sleep instability, and caregiver perception. The majority of studies identified restless sleep as reported by the caregiver, only 34 studies attempted to define restless sleep further. Four studies provided supportive evidence for designating restless sleep as an independent sleep disorder, restless sleep disorder (RSD). This review highlights the fact that the prevalence, etiology and sequelae (including daytime impairments) of restless sleep in children are important topics deserving of further research and that clinical definitions based on empirical evidence need to be developed. The designation of "primary" versus "secondary" restless sleep may be a useful construct, especially with regard to developing clinical trials and treatment algorithms.

Abstract
OBJECTIVES Given that 30%-50% of children with trisomy 21 have persistent obstructive sleep apnoea (OSA) after adenotonsillectomy, we evaluated whether demographic, clinical and polysomnographic factors predicted persistent OSA and OSA severity after adenotonsillectomy. DESIGN Retrospective study. SETTING Secondary care hospital. PARTICIPANTS Retrospective review of 32 children with the diagnosis of trisomy 21 and OSA by polysomnography who underwent adenotonsillectomy, from January 2010 to December 2018. MAIN OUTCOME AND MEASURE Non-parametric analysis was used to compare pre- and postoperative factors, and regression was used to model persistent OSA and OSA severity. RESULTS Thirty-two children were included (17 males, median age 10.00 ± 8.00 years, median body mass index z-score 0.89 ± 1.25). Overall, adenotonsillectomy resulted in a significant improvement in median obstructive apnoea-hypopnoea index (oAHI) from 7.5 ± 8.95 to 4.40 ± 4.38 events per hour (P < .001) and in median OSA-18 score from 85.00 ± 12.00 to 61.00 ± 37.75 (P < .001). Persistent OSA was found in 56.25% of the children. Univariate regression suggests that postoperative OSA-18 score was associated with persistent OSA after adenotonsillectomy. Preoperative oAHI, preoperative oxygen desaturation index, pre- and postoperative OSA-18 scores correlated with OSA severity after adenotonsillectomy. However, in a multivariate model only the postoperative OSA-18 score correlated with OSA severity after adenotonsillectomy. CONCLUSIONS Although adenotonsillectomy results in a significant improvement of OSA in children with trisomy 21, more than half of the children had persistent OSA. The postoperative OSA-18 score was associated both with persistent OSA and OSA severity after adenotonsillectomy.

Abstract
Pediatric obstructive sleep apnea affects a large number of children and has multiple end-organ sequelae. Although many of these have been demonstrated to be reversible, the effects on some of the organ systems, including the brain, have not shown easy reversibility. Progress in this area has been hampered by lack of a preclinical model to study the disease. Therefore, perioperative and sleep physicians are tasked with making a number of difficult decisions, including optimal surgical timing to prevent disease evolution, but also to keep the perioperative morbidity in a safe range for these patients.

Abstract
OBJECTIVE Cone-beam computed tomography (CBCT) offers three-dimensional structures in assessing upper airway of patients. This study aims to compare the cone-beam computerized tomography scan measurements between children with obstructive sleep apnea (OSA) and primary snoring. STUDY DESIGN Case-control study. METHODS This prospective study was conducted in a tertiary referral center. Thirty-six children with moderate-to-severe OSA (with apnea-hypopnea index [AHI] > 5 events/hour) and 36 age-, gender-, and obesity-matched children with primary snoring (AHI <1) were enrolled. The measurements in CBCT parameters were compared between children with moderate-to-severe OSA and primary snorers by conditional logistic regression model. RESULTS A total of 72 children (mean age, 7.9 ± 2.8 years; 64% male) were included. Children with moderate-to-severe OSA had a significantly smaller nasopharyngeal (2900 ± 1400 vs. 3800 ± 1800 mm3 , P = .017) and oropharyngeal airway volume (5600 ± 2700 vs. 7400 ± 4000 mm3 , P = .026) than those with primary snoring. Children with moderate-to-severe OSA, as compared to primary snorers, also had a significantly smaller minimal airway area in nasopharynx (77.4 ± 37.7 vs. 107.7 ± 52.0 mm2 , P = .006) and oropharynx (66.6 ± 61.9 vs. 101.6 ± 65.8 mm2 , P = .023). Moreover, the airway length was not significantly different between children with moderate-to-severe OSA and primary snoring. CONCLUSIONS The three-dimensional CBCT airway analysis could be used as a useful tool to evaluate upper airway in children with OSA. LEVEL OF EVIDENCE 3 Laryngoscope, 131:680-685, 2021.

Abstract
Background Pediatric obstructive sleep apnea/hypopnea syndrome (OSAHS) is a multifactorial syndrome caused by many risk factors, such as craniofacial anomalies, adenotonsillar hypertrophy, obesity, and airway inflammation. Although new treatment patterns have recently been proposed, treatment methods for children remain particularly challenging and controversial. This randomized controlled trial was designed to investigate the efficacy of adenotonsillectomy and/or orthodontic treatment for children who have mild OSAHS with mandibular retrognathia. Methods A sample of 352 children with mild OSAHS and mandibular retrognathia, who are aged between 7 and 10 years, will be enrolled in the study. They will be randomized into four groups: the drug treatment group, the surgical treatment group, the orthodontic treatment group, or the surgery and postoperative orthodontic group. After randomization the children will receive treatments within 4 weeks. Outcome assessment will take place at the following points: (1) baseline, (2) 7 months after the treatment starting point, (3) 12 months after the treatment starting point, and (4) 24 months after the treatment starting point. The primary endpoint of the trial is the mean change in obstructive apnea/hypopnea index. Other endpoints will consist of the lowest oxygen saturation, apnea index, and hypopnea index assessed by polysomnography, subjective symptoms (assessed by the OSA-20 questionnaire), cephalometric measurements, and morphologic analysis of the upper airway. Discussion The results of this study will provide valuable evidence for the merits and long-term efficacy of different treatment approaches and contribute to facilitating the multidisciplinary treatment of pediatric OSAHS. Trial registration ClinicalTrials.gov: NCT03451318. Registered on 2 March 2018 (last update posted 19 April 2018).

Abstract
Sleep is an important component in a child's growth and development. Snoring is common in children and often perceived as benign, but habitual snoring may be an indication of obstructive sleep apnoea (OSA). OSA can have health, developmental and cognitive consequences. The three common risk factors for paediatric OSA are tonsillar and/or adenoidal hypertrophy, obesity and allergic rhinitis. Primary care providers are well-placed to identify children at risk by screening for habitual snoring and associated OSA risk factors during routine consultations. Physician awareness of OSA symptoms/signs facilitates diagnosis, management and referral decisions. A trial of medical treatment may be considered for habitual snoring with mild symptoms/signs before referral. Overnight polysomnography is the gold standard investigation utilised by paediatric sleep specialists to diagnose OSA. Adenotonsillectomy is the first-line management for OSA with adenotonsillar hypertrophy, but residual/recurrent OSA may occur, so follow-up by primary care providers is important after surgery.

Abstract
INTRODUCTION The prevalence of obstructive sleep apnea (OSA) in the pediatric population with Down syndrome (DS) is reported to be 45-76%. The criterion "gold" standard for diagnosing OSA is polysomnography (PSG). First-hand surgical treatment is adenotonsillectomy (ATE), and another option is adenopharyngoplasty (APP). The aims of this study were to determine the OSA prevalence among children with DS who had undergone PSG and to evaluate and compare the efficiency and results of ATE and APP treatments. METHODS AND MATERIALS Children <18 years old with DS who underwent PSG at Karolinska University Hospital were included in this retrospective cohort study. Medical records were examined for patient age, sex, medical comorbidity diagnoses, and OSA treatment, and the results from PSG and the quality of life questionnaire OSA-18 were registered. The prevalence and degree of OSA were calculated. Results from a nonsystematic subgroup that underwent postoperative PSG and the OSA-18 were compiled to evaluate surgical efficiency. Pre- and postoperative results from APP and ATE patients were compared. RESULTS In the study, 138 DS children were included. The OSA prevalence was 82.6%, and 39.9% had severe OSA, with a median (range) apnea hypopnea index (AHI) of 7.6 (0-104). Other comorbidity diagnoses were found for ear disease in 60%, circulatory disease in 51% and endocrine disease in 39% of patients. A nonsystematic subgroup of 33 patients underwent postoperative PSG, with a residual prevalence of moderate or severe OSA of 63.6%. Among the ATE and APP patients with pre- and postoperative PSG (n = 20), no difference between the groups was shown, but the values were significantly improved as a whole: the median AHI changed from 21.1 to 12.4 and the median OSA-18 rating changed from 54.0 to 35.0. CONCLUSIONS In this population of children with DS, the OSA prevalence was over 80%, wherefore continued screening and treatment are strongly supported. Uncertain surgical efficiency was indicated, and no significant difference in the results for ATE and APP was shown. When interpreting the results, it should be taken into consideration that the frequency of postoperative PSG was low and nonsystematic and that the groups were unequal and small.

Relationships Among and Predictive Values of Obesity, Inflammation Markers, and Disease Severity in Pediatric Patients with Obstructive Sleep Apnea Before and After Adenotonsillectomy. J Clin Med 2020; 9:jcm9020579.

Abstract
Both obstructive sleep apnea (OSA) and obesity are major health issues that contribute to increased systemic inflammation in children. To date, adenotonsillectomy (AT) is still the first-line treatment for childhood OSA. However, the relationships among and predictive values of obesity, inflammation, and OSA severity have not been comprehensively investigated. This prospective study investigated body mass index (BMI), serum inflammatory markers, and OSA severity before and after AT in 60 pediatric patients with OSA. At baseline, differences in levels of interleukin-6, interleukin-9, basic fibroblast growth factor, platelet-derived growth factor-BB, as well as regulated on activation, normal T cell expressed and secreted (RANTES) were significant among the various weight status and OSA severity subgroups. After 3 months postoperatively, the differences in these inflammatory markers diminished along with a decrease in OSA severity while obesity persisted. The rate of surgical cure (defined as postoperative obstructive apnea-hypopnea index < 2.0 and obstructive apnea index < 1.0) was 62%. Multivariate analysis revealed that age, BMI z-score, granulocyte-macrophage colony-stimulating factor, monocyte chemotactic protein-1, and RANTES independently predicted surgical cure. Despite the significant reductions in inflammatory markers and OSA severity after AT, an inter-dependent relationship between obesity and OSA persisted. In addition to age and BMI, several inflammatory markers helped to precisely predict surgical cure.

Abstract
Non-invasive ventilation (NIV) and continuous positive airway pressure (CPAP) are effective treatments for children with severe sleep disordered breathing (SBD). However, some patients may present too severe SDB that do not respond to NIV/CPAP or insufficient compliance to treatment. A careful revaluation of the interface and of ventilator settings should be performed before considering alternative treatments. In patients with obstructive sleep apnea (OSA), alternatives to CPAP/NIV rely on the underlying disease. Ear-nose-throat (ENT) surgery such as adeno-tonsillectomy (AT), turbinectomy or supraglottoplasty represent an effective treatment in selected patients before starting CPAP/NIV and should be reconsidered in case of CPAP failure. Rapid maxillary expansion (RME) is restricted to children with OSA and a narrow palate who have little adenotonsillar tissue, or for those with residual OSA after AT. Weight loss is the first line therapy for obese children with OSA before starting CPAP and should remain a priority in the long-term. Selected patients may benefit from maxillo-facial surgery such as mandibular distraction osteogenesis (MDO) or from neurosurgery procedures like fronto-facial monobloc advancement. Nasopharyngeal airway (NPA) or high flow nasal cannula (HFNC) may constitute efficient alternatives to CPAP in selected patients. Hypoglossal nerve stimulation has been proposed in children with Down syndrome not tolerant to CPAP. Ultimately, tracheostomy represents the unique alternative in case of failure of all the above-mentioned treatments. All these treatments require a multidisciplinary approach with a personalized treatment tailored on the different diseases and sites of obstruction. In patients with neuromuscular, neurological or lung disorders, non-invasive management in case of NIV failure is more challenging. Diaphragmatic pacing has been proposed for some patients with central congenital hypoventilation syndrome (CCHS) or neurological disorders, however its experience in children is limited. Finally, invasive ventilation via tracheotomy represents again the ultimate alternative for children with severe disease and little or no ventilatory autonomy. However, ethical considerations weighting the efficacy against the burden of this treatment should be discussed before choosing this last option.

Abstract
Objective Adenotonsillectomy outcomes in obstructive sleep apnea (OSA) treatment among children with Prader-Willi syndrome (PWS) remain unclear. This study aimed to elucidate the effectiveness of adenotonsillectomy in OSA treatment among children with PWS. Data Source PubMed, MEDLINE, Embase, and Cochrane Review up to February 2019. Review Methods The registry number of the protocol published on PROSPERO was CRD42015027053. Two authors independently searched the relevant database. Polysomnography outcomes in these children were examined, including net postoperative changes in the apnea-hypopnea index (AHI), net postoperative changes in the minimum and mean oxygen saturation, the overall success rate for a postoperative AHI <1, and the overall success rate for a postoperative AHI <5. Results Six studies with 41 patients were analyzed (mean age, 5.0 years; 55% boys; mean sample size, 6.8 patients). All children had PWS and received adenotonsillectomy for the treatment of OSA. The AHI was 13.1 events per hour (95% CI, 11.0-15.1) before surgery and 4.6 events per hour (95% CI, 4.1-5.1) after surgery. The mean change in the AHI was a significant reduction of 8.0 events per hour (95% CI, −10.8 to −5.1). The overall success rate was 21% (95% CI, 11%-38%) for a postoperative AHI <1 and 71% (95% CI, 54%-83%) for a postoperative AHI <5. Some patients developed velopharyngeal insufficiency postoperatively. Conclusion Adenotonsillectomy was associated with OSA improvement among children with PWS. However, residual OSA was frequently observed postoperatively in these patients.
