RESUMO
PURPOSE: The aim of this study is to assess the effects of respiratory exercises (inspiratory and expiratory) in individuals with sleep bruxism (SB) and associated obstructive sleep apnea (OSA). METHODS: This is a double-blind, placebo-controlled randomized clinical trial including individuals with SB and associated respiratory events in OSA. Respiratory physical therapy was performed using inspiratory (Threshold® IMT), expiratory (Threshold® PEP) muscle training, and compared with a placebo group. A total of 30 daily respiratory cycles (inspiration and expiration) were performed five times a week for 12 weeks. Individuals were reassessed at two times, at baseline (T1) and after 12 weeks of training (T2) by means of the Pittsburgh Sleep Quality Index and Polysomnography. RESULTS: Awakening was significantly different (p ≤ 0.05) between the inspiratory group and placebo 12 weeks after respiratory physical therapy. The number of contractions of the masseter muscle differed between the inspiratory, expiratory, and placebo groups (p ≤ 0.05). CONCLUSION: Respiratory physical therapy for OSA improved awaking levels in 80 and 67% of the number of masseter muscle contractions, when compared to placebo. TRIAL REGISTRATION: Brazilian Registry of Clinical Trials (No. RBR-9F6JKM).

OBJECTIVES: To examine the feasibility of individuals with spinal cord injury or disease (SCI/D) to perform combined oropharyngeal and respiratory muscle training (RMT) and determine its impact on their respiratory function. METHODS: A prospective study at a single Veterans Affairs (VA) Medical Center. Inclusion criteria included: 1) Veterans with chronic SCI/D (>6 months postinjury and American Spinal Injury Association (ASIA) classification A-D) and 2) evidence of OSA by apnea-hypopnea index (AHI ≥5 events/h). Eligible participants were randomly assigned to either an experimental (exercise) group that involved performing daily inspiratory, expiratory (using POWERbreathe and Expiratory Muscle Strength Trainer 150 devices, respectively), and tongue strengthening exercises or a control (sham) group that involved using a sham device, for a 3-month period. Spirometry, maximal expiratory pressure (MEP), maximal inspiratory pressure (MIP), polysomnography, and sleep questionnaires were assessed at baseline and at 3 months. RESULTS: Twenty-four individuals were randomized (12 participants in each arm). A total of eight (67%) participants completed the exercise arm, and ten (83%) participants completed the sham arm. MIP was significantly increased (p < 0.05) in the exercise group compared with the baseline. CONCLUSIONS: Combined oropharyngeal and RMT are feasible for individuals with SCI/D. Future studies are needed to determine the clinical efficacy of these respiratory muscle exercises.

OBJECTIVE: Upper airway stimulation (UAS) is a treatment option for obstructive sleep apnea in which electrical stimulation is applied to the hypoglossal nerve. Nerve branches that control tongue protrusion are located inferiorly. Due to positioning, left-sided implants are typically placed with an inferiorly oriented electrode cuff (L-down) as opposed to superiorly on the right (R-up). In this study, we assess the impact of left- versus right-sided UAS on patient outcomes. STUDY DESIGN: Retrospective cohort study. SETTING: Tertiary Academic Medical Center. METHODS: Patients who underwent UAS implantation between 2016 and 2021 with an L-down or R-up oriented cuff as confirmed by X-ray were included. Data were collected retrospectively. Most recent sleep study variables were used for analysis. RESULTS: A total of 190 patients met the inclusion criteria. The average age was 61.0 ± 11.0 years, with 55 (28.9%) females. L-down orientation was present in 21 (11.1%) patients vs 169 (88.9%) R-up. Indications for L-down included hunting/shooting (n = 15), prior radiation/surgery (n = 4), central port (n = 1), and brachial plexus injury (n = 1). Adherence was higher among L-down patients (47.1 vs 41.0 hours use/week, P = .037) in univariate analysis, with a similar time to adherence data collection (4.4 vs 4.2 months, P = .612), though this finding was not maintained in the multivariate regression analysis. Decrease in apnea-hypopnea index (21.3 vs 22.8, P = .734), treatment success (76.5% vs 84.0%, P = .665), functional threshold (1.5 vs 1.6, P = .550), therapeutic amplitude (2.3 vs 2.4, P = .882), and decrease in Epworth Sleepiness Scale (4.9 vs 2.6, P = .060) were not significantly different between cohorts. CONCLUSION: This study is the first to examine the orientation of the UAS electrode cuff concerning the electrodes' natural position and the potential effect on postoperative outcomes. Our study found no significantly different treatment outcomes between the L-down versus R-up cohort, with the exception of device adherence, which was significantly higher in the L-down group on univariate analysis though not on multivariate analysis. Future studies with larger patient cohorts are needed to further investigate this potential relationship between treatment outcomes and electrode cuff orientation.

OBJECTIVE: Scar adherence due to a pathological healing process can cause physical and psychological disturbance. Soft tissue mobilisation (STM) techniques are widely used to treat and prevent scar adherence, but little is known on their effects. We aimed to analyse the effect of STM in patients with subacute post-surgical scar adhesions affecting the extremities. METHOD: A single-group quasi-experimental study was conducted on consecutive patients undergoing post-surgery limb rehabilitation. Patients with a baseline Adhesion Severity (AS) index of <0.5 at the worst scar point, as measured by the Adheremeter, were eligible. All patients who completed a minimum of five manual treatment sessions were included. The primary outcome was the AS index and the secondary outcome was the Italian version of the Patient and Observer Scar Assessment Scales (POSAS-I). RESULTS: A cohort of 19 patients underwent an average of eight STM sessions over a period of one month. The AS index value increased from a median of 0.12 at baseline (interquartile range (IQR): 0.05-0.25) to 0.41 post-treatment (IQR: 0.26-0.63; median change: 0.24; IQR: 0.16-0.40; p<0.001). A large effect size was observed for both AS and Observer Scar Assessment Scale (OSAS-I) (Cohen r=0.6), with a large probability of superiority (PS) (87% and 86%, respectively). A moderate effect was observed for the Patient Scar Assessment Scale (PSAS-I) (Cohen=0.4; PS=71%). Pre-post treatment changes exceeded the minimal detectable changes for the AS and OSAS-I in 68% of subjects, and for PSAS-I in 21% of subjects. CONCLUSION: STM manual techniques may produce a large effect on the mobility of adherent subacute post-surgical scars.

OBJECTIVE: The Food and Drug Administration recently approved upper airway stimulation (UAS) for children with Down Syndrome and persistent obstructive sleep apnea who meet certain inclusion and exclusion criteria. Although there is a robust experience with this therapy in the adult population, established protocols used in adults are not directly transferrable to a complex pediatric population. This review aims to combine the protocols from several institutions for patient selection and postimplantation optimization, including a protocol for Drug-Induced Sleep Endoscopy in children with Down Syndrome, preactivation threshold measurements, device titration, and follow-up sleep studies. STUDY DESIGN: Expert panel development of best Practice algorithm. SETTING: Multi-institutional investigator review. METHODS: An expert panel was assembled of pediatric otolaryngologists with extensive experience in hypoglossal nerve stimulation in children with Down Syndrome. Thirty statements were created during an initial drafting session. A modified Delphi method was used assess consensus among the panel. RESULTS: After 2 rounds of Delphi surveys, 29 statements met criteria for consensus. One statement did not meet consensus. The statements were grouped into several categories to facilitate presentation. CONCLUSIONS: A standardized approach to UAS for children with Down Syndrome must take into account the unique challenges inherent to treating a complex pediatric population with a high rate of sensory processing disorders. This expert panel has met consensus on several statements that will guide clinicians as this novel therapy is adopted.

CASE: X is a 22-month-old White male infant with a complex medical history, including diagnoses of FBXO11 mutation, hypotonia, restrictive lung disease and mild intermittent asthma, laryngotracheomalacia, obstructive sleep apnea (OSA), feeding difficulties with a history of aspiration, gastroesophageal reflux disease (GERD), and developmental delays. X's medical presentation has resulted in multiple prior medical admissions for respiratory failure due to acute illnesses, procedures and treatments including gastrojejunostomy (GJ) tube dependence, supraglottoplasty to reshape tissues of the upper larynx, and the use of biphasic positive airway pressure (BiPAP) at night and room air during the day when he is at baseline. In addition, he has nocturnal events characterized by significant agitation, screaming, crying, body stiffening and limb movements with pauses in breathing, mouth breathing, restless sleep, and difficulty waking in the morning with concomitant daytime fatigue despite above treatments for OSA. There is no history of congenital heart disease or sudden unexplained death. Family history is noncontributory because parents are negative for the FBXO11 variant.X's sleep disruption has led to significant sleep deficits for both X and his caregivers, who spend much of the night strategizing on how to console him. X has undergone several sleep studies, starting when X was aged 4 months, at several children's hospitals across the nation to determine the cause of his chronic sleep disturbance, which yielded limited information and treatment success. As an infant, X received a medical workup and was subsequently treated with a proton pump inhibitor (PPI) for reflux. At 12 months, he was diagnosed with disordered sleep with myoclonic jerks and started on melatonin and gabapentin for involuntary movements. At 13 months, gabapentin was weaned back because of intolerance, and at 15 months, nortriptyline and clonidine were started because of worsening symptoms to target potential neuropathic pain. While most of his symptoms were at night, he had occasional daytime screaming episodes, particularly when experiencing illness. Gabapentin and clonidine were stopped because nortriptyline seemed most effective.At 17 months, the results from a sleep study led to a diagnosis of night terrors, and several clinicians agreed that X's sleep disruption was behavioral in nature. At this time, an infant mental health consultant met with a sleep psychologist on the family's behalf to support family in considering systematic desensitization therapy to increase tolerance to wearing his BiPAP mask, as well as other behavioral and sleep hygiene strategies, which were tried on several occasions and again, resulted in limited improvement in functioning.At 19 months, X's multidisciplinary team reconsidered a night terror diagnosis after a failed trial of clonazepam and pursued a differential diagnosis of periodic limb movement disorder (PLMD). X trialed gabapentin again, but this time only a nighttime dose, per sleep medicine and psychiatry recommendation. While this brought some temporary relief from nighttime distress, despite increasing to the highest dose for age and weight (15 mg/kg/dose), this became less effective, and he was weaned off at 22 months. He had been on iron supplementation since age 6 months and received an iron infusion at 22 months because of persistently low ferritin levels and PLMD in sleep.At 24 months, X was briefly trialed on levetiracetam. While no evidence for seizures on EEG was present, this medication was chosen for involuntary movements and genetic risk for seizures. However, this medication was not useful. At 25 months, an evaluation with a movement disorder physiatrist resulted in a diagnosis of nocturnal paroxysmal dystonia, and he was started on baclofen, which has provided some, but not complete relief to nighttime symptoms. Parents are reporting he has more "good nights" than "bad nights," but "bad nights" come in stretches of a few days in length with no known trigger or relief.Most recently, X was evaluated by general genetics. Whole exome sequencing (WES) was pursued which revealed a pathogenic de novo variant in FBXO11 and provides a likely cause for his neurodevelopmental phenotype. However, he has some features not explained by FBX011; thus, reanalysis of his WES was performed and revealed a de novo variant of uncertain significance in RAF1. Because pathogenic variants in RAF1 have been associated with dilated cardiomyopathy and Noonan spectrum disorder, it was recommended that X be followed periodically in a cardiac genetics clinic. Family is well connected into the FBXO11 community, including supportive Facebook groups. Parents have shared that they do not feel X's breathing issues and pain fit with the phenotype of other children with FBXO11 mutations.X is also enrolled in a medical child care program to facilitate development and social-emotional functioning and receives learning, speech, occupational, physical, and feeding therapy while in attendance. Despite periods of absence due to contracting numerous viral illnesses over the past several months, X continues to make progress across developmental therapies and happily engages when at the program.What additional diagnostic tests and treatment should be considered to better understand X's medical and behavioral presentation? What are the implications of chronic sleep deprivation and stress on the behavior and development of infant with X's profile? What are important psychosocial considerations because it relates to children with medical complexity (CMC), particularly for X and his family to support caregiver, family, and X's quality of life and overall well-being?

PURPOSE: To evaluate the efficacy of upper airway stimulation therapy in patients with a floppy epiglottis who have experienced continuous positive airway pressure failure or intolerance. METHODS: A retrospective single-center cohort study was conducted. Patients who received an Inspire Upper Airway Stimulation system and had a 1-year follow-up were included. Baseline and one-year in-laboratory polysomnography examinations were performed. Patient characteristics, Epworth Sleepiness Scale scores and upper airway stimulation device settings were collected. RESULTS: A total of 75 patients were included, of whom 10 had a floppy epiglottis. Patients with a floppy epiglottis had a significant therapeutic response to upper airway stimulation therapy, similar to patients without a floppy epiglottis. According to the Sher's success criteria, 90% of patients with a floppy epiglottis and 68% of patients without a floppy epiglottis were responders to therapy (p = 0.149). In the floppy epiglottis group, the apnea-hypopnea index decreased from 35.1 ± 5.5 events/hour to 11.2 ± 11.3 events/hour (95% CI (15.0, 32.9), p < 0.001), similarly in the non-floppy epiglottis group, the decline was from 36.4 ± 8.3 events/hour to 14.4 ± 9.5 events/hour (95% CI (18.6, 25.2), p < 0.001, between groups p = 0.659). Comparable reductions were observed for the other respiratory parameters. CONCLUSION: Treatment of patients with obstructive sleep apnea and a floppy epiglottis can be challenging. Continuous positive airway pressure may aggravate the epiglottis collapse. Upper airway stimulation therapy can be considered an effective alternative treatment option for patients with a floppy epiglottis who have encountered either continuous positive airway pressure failure or intolerance.

OBJECTIVE: This study aims to define the incidence of infection with upper airway stimulation (UAS) devices requiring explantation in a single academic center and identify factors that may influence the risk of infection. METHODS: A database of patients who underwent UAS at a single tertiary referral academic center from 2017 to 2021 was retrospectively reviewed to identify patients who developed surgical site infections, with and without subsequent explantation. Additional data for cases complicated by infection was extracted from the electronic medical record (EMR) and included: demographic information, medical history, complications and management, and overall outcomes. In March 2021, 2 modifications to infection control protocols were implemented: double skin preparation with Betadine and chlorhexidine, and MRSA decolonization. Statistical analysis was performed to compare infectious risk before and after these protocol changes. RESULTS: In the study period, 215 patients underwent UAS in the specified time period and 3 cases (1.4%) of postoperative infections were identified, all of which required explantation. The infection rate did not significantly change after modifications to the surgical prep protocol (P = .52). CONCLUSIONS: While no significant difference in infection risk was noted after modifying infection control protocols, additional longer-term study is warranted to elucidate effective infection reduction strategies.

STUDY OBJECTIVES: Sleep fragmentation and daytime sleepiness often persist in patients with sleep apnea despite correctly administered continuous positive airway pressure (CPAP). Our proof-of-concept study tested the acceptability and efficacy of morning bright light therapy (BLT) to improve sleep, circadian rhythms, and CPAP-resistant daytime symptoms in patients with sleep apnea. METHODS: In this within-subject crossover study, 14 individuals completed 4 weeks of BLT and sham BLT in randomized order. Outcomes included actigraphy-based objective sleep measures, sleepiness, depressive symptoms, and sleep-related functional impairment, analyzed with multilevel models. RESULTS: Patients experienced greater reductions in wake after sleep onset and increased amplitude of rest-activity rhythms in a shorter photoperiod with BLT compared with sham. Patients also reported reductions in self-reported sleepiness and depressive symptoms with BLT compared with sham only during the early stages of treatment and shorter photoperiod. CONCLUSIONS: These results suggest the potential for novel applications for existing chronotherapeutic interventions for improving symptoms and quality of life for those patients who experience residual symptoms with current available treatments.

Importance: Sham-controlled trials are needed to characterize the effect of hypoglossal nerve stimulation (HGNS) therapy on cardiovascular end points in patients with moderate-severe obstructive sleep apnea (OSA). Objective: To determine the effect of therapeutic levels of HGNS, compared to sham levels, on blood pressure, sympathetic activity, and vascular function. Design, Setting, and Participants: This double-blind, sham-controlled, randomized crossover therapy trial was conducted from 2018 to 2022 at 3 separate academic medical centers. Adult patients with OSA who already had an HGNS device implanted and were adherent and clinically optimized to HGNS therapy were included. Participants who had fallen asleep while driving within 1 year prior to HGNS implantation were excluded from the trial. Data analysis was performed from January to September 2022. Interventions: Participants underwent a 4-week period of active HGNS therapy and a 4-week period of sham HGNS therapy in a randomized order. Each 4-week period concluded with collection of 24-hour ambulatory blood pressure monitoring (ABPM), pre-ejection period (PEP), and flow-mediated dilation (FMD) values. Main Outcomes and Measures: The change in mean 24-hour systolic blood pressure was the primary outcome, with other ABPM end points exploratory, and PEP and FMD were cosecondary end points. Results: Participants (n = 60) were older (mean [SD] age, 67.3 [9.9] years), overweight (mean [SD] body mass index, calculated as weight in kilograms divided by height in meters squared, 28.7 [4.6]), predominantly male (38 [63%]), and had severe OSA at baseline (mean [SD] apnea-hypopnea index, 33.1 [14.9] events/h). There were no differences observed between active and sham therapy in 24-hour systolic blood pressure (mean change on active therapy, -0.18 [95% CI, -2.21 to 1.84] mm Hg), PEP (mean change on active therapy, 0.11 [95% CI, -5.43 to 5.66] milliseconds), or FMD (mean change on active therapy, -0.17% [95% CI, -1.88% to 1.54%]). Larger differences between active and sham therapy were observed in a per-protocol analysis set (n = 20) defined as experiencing at least a 50% reduction in apnea-hypopnea index between sham and active treatment. Conclusions and Relevance: In this sham-controlled HGNS randomized clinical trial, mean 24-hour systolic blood pressure and other cardiovascular measures were not significantly different between sham and active HGNS therapy. Several methodologic lessons can be gleaned to inform future HGNS randomized clinical trials. Trial Registration: ClinicalTrials.gov Identifier: NCT03359096.

Guidelines for management of sleep disorders from national or regional societies provide recommendations that may be regionally appropriate but may not always be practical or relevant in other parts of the world. A task force of experts from the World Sleep Society's (WSS) International Sleep Medicine Guidelines Committee and Sleep and Breathing Disorders Task Force reviewed the European Respiratory Society's guideline on non-CPAP therapies for obstructive sleep apnea (OSA) with respect to its relevance and applicability to the practice of sleep medicine by sleep specialists in various regions of the world. The task force and the WSS guidelines committee endorsed the European Respiratory Society's guideline with respect to the utilization of bariatric surgery, mandibular advancement devices, positioning devices, myofunctional therapy, hypoglossal neurostimulation, maxilo-mandibular surgery, and carbonic anhydrase inhibitors for the treatment of OSA. The task force and the WSS guidelines committee noted that there is substantial new evidence for the role of soft tissue, upper airway surgery, not included in the guidelines paper.

OBJECTIVE: Tracheostomy is performed for various indications ranging from prolonged ventilation to airway obstruction. Many factors may play a role in the incidence of complications in the immediate post-operative period including patient-related factors. Chronic obstructive pulmonary disease and asthma are some of the most common pulmonary pathologies in the United States. The relationship between obstructive pulmonary diseases and acute post-tracheostomy complications has been incompletely studied. DESIGN: A retrospective chart review was designed in order to answer these objectives. Medical records were reviewed for the technique used, complications, and contributing patient factors. Post-operative complications were defined as any tracheostomy-related adverse event occurring within 14 days. SETTING: The study took place at an academic comprehensive cancer. PARTICIPANTS: Inclusion criteria included patients from January 2017 through December 2018 who underwent a tracheostomy. Exclusion criteria included presence of stomaplasty, total laryngectomy, and tracheostomies performed at outside hospitals. MAIN OUTCOME MEASURES: Patient factors examined included demographics, comorbidities, and body mass index with the primary outcome measured being the rate of tracheostomy complications. RESULTS: The most common indication for tracheostomy among the 321 patients that met inclusion criteria was airway obstruction or a head and neck cancer surgical procedure. Obstructive sleep apnea was associated with acute complications in bivariate analysis (29.4% complications, p = .003). Chronic obstructive pulmonary disease and asthma were not associated with acute complications in bivariate analysis (11.6% complications, p = .302). Among the secondary outcomes measured, radiation was associated with early complications occurring in post-operative days 0-6 (1.1%, p = .029). CONCLUSION: Patients with obstructive sleep apnea may have a higher risk of acute post-tracheostomy complications that might be due to the patient population at risk for obstructive sleep apnea. Patients with obstructive pulmonary pathologies such as asthma or chronic obstructive pulmonary disorder did not have an elevated risk of complications which is clinically significant when considering the utility of ventilation and tracheostomy in the management of acute respiratory failure secondary to these conditions.

OBJECTIVE: Orofacial myofunctional therapy (OMT) is an alternative form of treatment of obstructive sleep apnea (OSA), that incorporates various exercises to optimize tongue placement and increase oropharyngeal tone. The objective of this systematic review and meta-analysis is to determine the efficacy of OMT in OSA patients. DATA SOURCES: PubMed/Medline, EMBASE, Cochrane, Web of Science. REVIEW METHODS: Using PRISMA guidelines, a directed search strategy was performed for randomized control trials (RCTs) published prior to March 24, 2023, featuring 10+ patients with OSA undergoing mono-therapeutic OMT. The primary outcome of interest was apnea-hypopnea index (AHI). Secondary outcomes included subjective sleepiness, sleep-related quality-of-life, and snoring frequency. RESULTS: Of the 1244 abstracts that were identified, 7 RCTs involving 310 patients met inclusion criteria. Adult OMT patients had a statistically significant improvement in AHI (MD -10.2; 95% CI, -15.6, -4.8, p < 0.05), subjective sleepiness (Epworth Sleepiness Scale; MD -5.66; 95% CI, -6.82, -4.5, p < 0.05), sleep-related quality-of-life (Pittsburgh Sleep Quality Index; MD -3.00; 95% CI, -4.52, -1.49, p < 0.05), and minimum oxygen saturation (MD 2.71; 95% CI, 0.23, 5.18, p < 0.05) when compared with sham OMT or no therapy. Within the single RCT featuring pediatric OMT patients, patients had poor compliance (<50%) and did not show any improvements in AHI, minimum oxygen saturation, or snoring frequency. CONCLUSION: OMT may provide a reasonable alternative for OSA patients who cannot tolerate CPAP or other more established treatment options. OMT benefits appear limited in children due to poor compliance. More studies are required to evaluate compliance and the long-term effects of OMT on OSA outcomes.

OBJECTIVE: We aimed to determine the preoperative prevalence of insomnia in the Adherence and Outcomes of Upper Airway Stimulation for OSA International Registry (ADHERE) and to examine serial sleep-related data longitudinally, in particular the Insomnia Severity Index (ISI), to compare outcomes between patients with no/subthreshold insomnia (ISI < 15) and moderate/severe insomnia (ISI ≥ 15) at baseline. METHODS: We analyzed observational data from ADHERE between March 2020 and September 2022. Baseline demographic and mental health (MH) data, apnea hypopnea index (AHI), ISI, and ESS (Epworth Sleepiness Scale) were recorded. At post-titration (PT) and final visits, AHI, ISI, ESS and nightly usage were compared between baseline ISI < 15 and ISI ≥ 15 subgroups. RESULTS: A baseline ISI was obtained in 928 patients (62% with ISI ≥ 15). Of the 578 and 141 patients reaching the 12- and 24-month time periods to complete PT and final visits, 292 (50.5%) and 91 (64.5%) completed the ISI, respectively. Baseline MH conditions were higher with ISI ≥ 15 than ISI < 15 (p < 0.001). AHI reduction and adherence did not differ between patients with baseline ISI ≥ 15 and ISI < 15. Patients with ISI ≥ 15 experienced greater improvement in ESS than ISI < 15 at post-titration and final visits (p = 0.014, 0.025). All patients had improved nocturnal, daytime, and overall ISI scores at follow-up visits (p < 0.001), especially for those with baseline ISI ≥ 15 compared with ISI < 15 (p < 0.05). CONCLUSION: HGNS therapy efficacy and adherence were similar between ISI severity subgroups at follow-up visits. Insomnia and sleepiness scores improved in all patients with HGNS therapy and to a greater degree in patients with baseline moderate/severe insomnia.

INTRODUCTION: The Hypoglossal Nerve Stimulator (HNS) is a novel therapy that has been extensively studied in adults and more recently, it has been incorporated in children with Down Syndrome (DS) with persistent obstructive sleep apnea after adenotonsillectomy and trial of continuous positive airway pressure treatment. This systematic review article aims to examine the existing literature on HNS use in children to explore the benefits, efficacy, and parental experiences. METHODS: MEDLINE, Web of Science and EMBASE were searched to include all studies published up to March 2nd, 2023, on the topic of HNS use in pediatric population under 21 years old. RESULTS: A total of 179 studies were initially identified from which 10 articles were consistent with the inclusion criteria. Nine articles addressed outcomes after implantation of the HNS device in children with DS and 1 article explored the parental experiences. Findings were similar across studies where after implantation of HNS, there was marked improvement in polysomnographic outcomes and quality of life scores with high level of compliance. CONCLUSIONS: HNS holds promise as an effective treatment option for pediatric patients with DS and persistent OSA after AT and CPAP trials. It significantly improves sleep-disordered breathing, quality of life, and neurocognitive measures, leading to substantial and sustained benefits for these children. While the findings are encouraging, further research is needed to explore the potential of HNS in other pediatric populations without DS and to raise awareness among healthcare providers about this treatment option. Overall, HNS may offer significant long-term benefits for the overall well-being and health of pediatric patients with DS and persistent OSA.

OBJECTIVES: This study aimed to determine the efficacy of hypoglossal nerve stimulation (HGS) in the treatment of obstructive sleep apnea. DATA SOURCES: PubMed, Cochrane database, Embase, Web of Science, SCOPUS, and Google Scholar. REVIEW METHODS: Five databases were reviewed to identify relevant studies that measured polysomnography parameters such as the apnea-hypopnea index (AHI) and oxygen desaturation index, as well as quality of life and functional outcomes of sleep questionnaire scores, before and after HGS. RESULTS: In total, 44 studies involving 8670 patients met the inclusion criteria. At 12 months after treatment, approximately 47%, 72%, and 82% of patients achieved AHI values of <5, < 10, and <15, respectively. The reported clinical success rates according to Sher criteria were 80% within 12 months and 73% between 12 and 36 months. While the favorable effects exhibited a gradual reduction up to 12 months postimplantation, they generally maintained a consistent level between the 12th and 36th months, as assessed by AHI < 5, <15, and success rate according to Sher criteria. CONCLUSION: HGS can enhance quality of life scores and polysomnography outcomes in obstructive sleep apnea patients. Although the positive effects gradually decreased until 12 months after implantation, they generally remained consistent between 12 and 36 months.

INTRODUCTION: Hypoglossal nerve stimulation was recently FDA approved for use in children with Down Syndrome and persistent obstructive sleep apnea. Although there is a robust experience in hypoglossal nerve stimulation in adults, we observed several challenges that are unique to providing this therapy to a complex pediatric population with a high rate of sensory processing disorders. We sought to review the adverse events and challenges to inform clinicians as hypoglossal nerve stimulation becomes a more accessible option for this complex population. METHODS: Retrospective case series of children with Down Syndrome and persistent OSA who underwent hypoglossal nerve stimulation. Inclusion and exclusion criteria included Down Syndrome, age 10-22 years, persistent severe OSA after adenotonsillectomy (AHI>10 with <25 % central or mixed events), inability to tolerate positive airway pressure, and absence of concentric palatal collapse on sleep endoscopy. Patients were identified and their charts were reviewed. Adverse events and their subsequent management were recorded. The major outcome variable was the total number of adverse events. RESULTS: A total of 53 patients underwent implantation of a hypoglossal nerve stimulator; 35 (66 %) patients were male and the average age at implantation was 15.1 years (standard deviation 3.0y). A total of 30 adverse events were noted, including 17 nonserious and 13 serious. The most common nonserious complications included temporary tongue discomfort, rash at the surgical site, and cellulitis. Serious complications included readmission (for cellulitis, pain, and device extrusion), reoperation (most commonly for battery depletion) and pressure ulcer formation. CONCLUSION: Hypoglossal nerve stimulation provides a much-needed therapy for children with DS and persistent OSA after adenotonsillectomy. Although there is a robust experience in providing this treatment to adults, many considerations must be made when adapting this technology to a pediatric population with a high rate of sensory processing disorders.
