Objectives Surgical intervention for obstructive sleep apnea (OSA) in overweight and obese children may not be as effective as it is in normal-weight children. The purpose of this study was to systematically review the effects of various surgical interventions for OSA in obese children and to meta-analyze the current data. Data Sources PubMed, OVID, and Cochrane databases. Review Methods Databases were searched for studies examining adenotonsillectomy, uvulopalatopharyngoplasty, supraglottoplasty, or tongue base surgeries and combinations in obese children with OSA. Adenotonsillectomy was the only procedure with enough data for meta-analysis; polysomnographic data were extracted and analyzed using a random-effects model. Results For adenotonsillectomy, 11 studies were included in the meta-analysis. Despite significant improvement in the apnea-hypopnea index (22.9 to 8.1 events/h, P < .001), respiratory disturbance index (24.8 to 10.4 events/h, P < .001), and oxygen saturation nadir (78.4% to 87.0%, P < .001), rates of persistent OSA ranged from 51% to 66%, depending on the outcome criterion used. There was evidence of limited effectiveness for surgical interventions to treat OSA in obese children using uvulopalatoplasty (12.5%) and tongue base surgery (74%-88%). Conclusions Surgical interventions for OSA in overweight and obese children are effective at reducing OSA but with higher rates of persistent OSA than reported for normal-weight children. However, the amount of reduction appears to vary by surgical procedure. More attention should be paid toward preoperative weight loss and patient selection, and parents should be provided with realistic postoperative expectations in this difficult-to-treat population.

OBJECTIVES: 1) To evaluate the relative severity of obstructive sleep apnea (OSA) in obese and normal-weight children; 2) to compare changes in respiratory parameters after adenotonsillectomy in obese and normal-weight children. STUDY DESIGN AND SETTING: Prospective controlled trial that included children aged 3 to 18 years. All study participants underwent pre- and postoperative polysomnography. RESULTS: The study population included 33 obese children and 39 normal-weight controls. Preoperatively, the median obstructive apnea-hypopnea index (AHI) was 23.4 (range 3.7-135.1) for obese and 17.1 (range 3.9-36.5) for controls ( P < 0.001). Postoperatively, the AHI was 3.1 (range 0-33.1) for obese and 1.9 (range 0.1-7.0) for controls ( P < 0.01). Twenty-five obese children (76%) and 11 controls (28%) had persistent OSA. CONCLUSION AND SIGNIFICANCE: AHI scores are higher in obese than in normal-weight children with OSA. Both groups show a dramatic improvement in AHI after adenotonsillectomy, but persistent OSA is more common in obese children.

Objective: There is a high prevalence of obstructive sleep apnea (OSA) in pediatric and adult Down Syndrome (DS) patients that is refractory to adenotonsillectomy and continuous positive airway pressure. Newer treatment modalities have emerged with improved outcomes. The objective is to provide an updated systematic review and meta-analysis to analyze the clinical outcomes of OSA in pediatric and adult DS patients with hypoglossal nerve stimulation using Inspire, midline posterior glossectomy plus lingual tonsillectomy (MPG + LT), and combined genioglossus advancement plus radiofrequency (GGS + RF). Methods: A comprehensive literature search of PubMed and Google Scholar was performed followed by a meta-analysis. Studies with preoperative and post-operative Apnea Hypopnea Index (AHI) values were included with patients serving as their own control. Results: Across 5 studies, 56 patients were analyzed. The mean reduction in AHI was statistically significant before vs. after procedure ( P < .001 for hypoglossal nerve stimulation using Inspire with a paired 2-tailed t-test and P = .031 for MPG + LT). Although individual patient AHI values were unavailable in the GGS + RF study, the standard difference in mean AHI was also significant for GGS + RF with P = .001. Device malfunction was the most common complication for Inspire while postoperative bleeding was observed for MPG + LT and nasopharyngeal obstruction and retropalatal collapse were observed for GGS + RF. Conclusion: This review reveals significant improvement in AHI with Inspire, MPG + LT, and GGS + RF for DS patients with refractory OSA. Further investigation is needed for comparison between these 3 therapies.

Abstract Background Obstructive sleep apnea (OSA) is a common disorder characterized by upper airway collapse requiring nocturnal ventilatory assistance. Multiple studies have investigated the relationship between acromegaly and OSA, reporting discordant results. Aim To conduct a meta-analysis on the risk for OSA in acromegaly, and in particular to assess the role of disease activity and the effect of treatments. Methods and Study Selection A search through literature databases retrieved 21 articles for a total of 24 studies (n = 734). Selected outcomes were OSA prevalence and apnea-hypopnea index (AHI) in studies comparing acromegalic patients with active (ACT) vs inactive (INACT) disease and pretreatment and posttreatment measures. Factors used for moderator and meta-regression analysis included the percentage of patients with severe OSA, patient sex, age, body mass index, levels of insulin-like growth factor 1, disease duration and follow-up, and therapy. Results OSA prevalence was similar in patients with acromegaly who had ACT and INACT disease (ES = −0.16; 95% CI, −0.47 to 0.15; number of studies [k] = 10; P = 0.32). In addition, AHI was similar in ACT and INACT acromegaly patients (ES = −0.03; 95% CI, −0.49 to 0.43; k = 6; P = 0.89). When AHI was compared before and after treatment in patients with acromegaly (median follow-up of 6 months), a significant improvement was observed after treatment (ES = −0.36; 95% CI, −0.49 to −0.23; k = 10; P &lt; 0.0001). In moderator analysis, the percentage of patients with severe OSA in the populations significantly influenced the difference in OSA prevalence (P = 0.038) and AHI (P = 0.04) in ACT vs INACT patients. Conclusion Prevalence of OSA and AHI is similar in ACT and INACT patients in cross-sectional studies. However, when AHI was measured longitudinally before and after treatment, a significant improvement was observed after treatment.

Objective Positional obstructive sleep apnea (POSA)—defined as obstructive sleep apnea twice as severe supine than nonsupine—may offer clues to the underlying pattern of upper airway collapse in children. We compared drug-induced sleep endoscopy (DISE) findings in children with and without POSA. We hypothesized that children with POSA would have significantly higher obstruction at the gravity-dependent palate and tongue base but not at the adenoid, lateral wall, or supraglottis. Study Design Retrospective case series. Setting Tertiary pediatric hospital. Subjects and Methods We included children aged 1 to 12 years with obstructive sleep apnea diagnosed by polysomnography who underwent DISE from July 2014 to February 2019. Scores were dichotomized as ≥50% obstruction (Chan-Parikh 2 or 3) vs <50% obstruction (Chan-Parikh 0 or 1). Results Of 99 children included, 32 (32%) had POSA and 67 (68%) did not. Children with POSA did not differ from children without POSA in age, overall apnea-hypopnea index, sex, race, syndromic diagnoses, obesity, or history of adenotonsillectomy. In logistic regression models, odds of ≥50% obstruction were significantly higher at the tongue base (odds ratio, 2.77; 95% CI, 1.04-7.39) after adjustment for age, sex, obesity, previous adenotonsillectomy, and syndrome. No difference was noted at the adenoid, velum, lateral wall, or supraglottis. Conclusion POSA was associated with higher odds of obstruction on DISE at the tongue base but not at other levels.

Abstract Introduction OSA affects 2-4% of children and untreated OSA can have adverse behavior and quality of life outcomes. 40% of children can have residual obstructive sleep apnea (OSA)despite first line treatment (adenotonsillectomy). Alternative modalities of treatment for OSA are limited. Myofunctional therapy comprises of exercises targeting upper airway muscles that can improve facial growth and have been shown to treat OSA in adults. There is paucity of data on the role of myofunctional therapy (MT) in children. The objective of this study was to systematically review the literature for articles evaluating myofunctional therapy (MT) as treatment for OSA in children and to perform a meta-analysis on the polysomnographic and mouth breathing data. Methods Medline, Embase, CINAHL, Scopus, Web of Science and Cochrane were searched from inception through October 1st, 2019. The Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) statement was followed. Results Eight studies (91 patients) reported polysomnography and/or mouth breathing outcomes. The pre- and post-MT apnea hypopnea indices (AHI) decreased from a mean ± standard deviation (M ± SD) of 3.75± 3.14/h to 2.08 ± 2.48/h, mean difference (MD) -1.6 [95% confidence interval (CI) -2.42, -0.78], P =0.0001. Mean oxygen saturations improved from 96.03 ± 1.1% to 96.67 ± 0.95%, MD 0.42 (95% CI 0.21, 0.63), P &lt;0.0001. Lowest oxygen saturations improved from 86.6 ± 7.3% to 90.94 ± 3.05%, MD 1.01 (95% CI 0.25, 1.77), P = 0.009. Mouth breathing decreased in all three studies reporting subjective outcomes. Conclusion Current literature demonstrates that myofunctional therapy decreases apnea-hypopnea index by approximately 45% in children with mild obstructive sleep apnea. Mean oxygen saturations, lowest oxygen saturations and mouth breathing outcomes improved in children. Myofunctional therapy could serve as an adjunct to other obstructive sleep apnea treatments.

Lingual Tonsillectomy

Objective To determine the role of lingual tonsillectomy (LT) in pediatric patients with persistent obstructive sleep apnea (OSA) after tonsillectomy and adenoidectomy (T&A). Data Sources PubMed, OVID-MEDLINE, and Cochrane Central from 2006 to 2017. Review Methods Inclusion criteria included English-language studies containing original data on LT in pediatric patients with persistent OSA. Exclusion criteria included case reports and studies without outcome measures. Two investigators independently reviewed all manuscripts and performed quality assessment using validated tools. Meta-analysis was performed. Results Of the 866 abstracts identified, 5 studies met inclusion criteria. All studies were case series (level of evidence 4). Outcome measures included apnea-hypopnea index (AHI), minimum oxygen saturation (minSaO2), comorbidity status, and adverse events. Qualitatively, all studies demonstrated reduction in AHI and increase in minSaO2 after LT. Comorbidities may not affect the success of LT for lingual tonsil hypertrophy (LTH). LT had similar adverse event rates as T&A. Meta-analysis was performed on 4 studies. LT showed a mean change in reduction of AHI and increase of minSaO2 of −6.64 (95% CI, −8.63 to −4.65) and 4.17 (95% CI, 1.25-7.08), respectively. The overall success rate, defined as postoperative AHI <5, was 52%. Conclusion LT for LTH can be a safe and effective adjunct surgery for persistent OSA in patients after T&A. LT may reduce AHI and increase minSaO2, though complete resolution of OSA is rare. Given the limited number of patients studied, no formal recommendations can be made for the routine use of LT for LTH in persistent pediatric OSA.

Objective: Both obesity and craniofacial deformity are important etiologies of obstructive sleep apnea (OSA). The present research aimed to explore their interaction and different impacts on OSA severity. Methods: A total of 207 consecutive OSA patients (169 males, 38 females) were included in the research. Based on the body mass index (BMI) value, patients were divided into 77 normal-weight patients (BMI <24 kg m−2), 105 overweight patients (24 ≤ BMI<28 kg m−2) and 26 obese patients (BMI ≥28 kg m−2). All accepted overnight polysomnography and standard lateral cephalogram. Cephalometric measurements involved 25 cephalometric variables. The correlations between these cephalometric variables, BMI and the apnea-hypopnea index (AHI) were evaluated. Results: For the whole sample after controlling for gender and age, stepwise regression analysis showed that the factors affecting AHI were increased BMI, narrowing posterior airway space, inferior displacement of hyoid and elongation of the tongue. When grouped by BMI, normal-weight group exhibited with more reduced maxillary length and mandible length, and steeper mandible plane than overweight and obese patients (p < 0.0167). Obese group showed least skeletal restriction and most prominent soft tissues enlargement (p < 0.0167). However, these skeletal indexes were not statistically correlated with AHI. Conclusions: Obesity and skeletal malformations were both etiological factors of OSA, but obesity seemed to have a greater influence on AHI severity in all kinds of obese and thin OSA patients. Only in normal-weight group, it was affected by both cephalometric variables and BMI.
