Impacts of conservative treatment on the clinical manifestations of obstructive sleep apnea-systematic review and meta-analysis. Sleep Breath 2024:10.1007/s11325-024-03034-z. [PMID: 38642201 DOI: 10.1007/s11325-024-03034-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/13/2023] [Revised: 03/08/2024] [Accepted: 04/08/2024] [Indexed: 04/22/2024]
Abstract
INTRODUCTION Obstructive sleep apnea (OSA) is a chronic disease with a high populational prevalence that is characterized as airway closure during sleep. Treatment is multidisciplinary and varies according to each case. Continuous positive airway pressure (CPAP), oral appliances, and surgery are the primary therapeutic options. Non-invasive conservative treatments such as sleep hygiene, positional therapy, physical exercises, and weight loss aim to reduce the worsening of the disease while being complementary to the invasive primary treatment. OBJECTIVE To analyze the impact of non-invasive conservative therapies on the clinical manifestations of OSA syndrome (OSA), compared with other interventions. METHOD This was a systematic review with meta-analysis. The searches were performed without filters for the time period, type of publication, or language. Randomized clinical trials on subjects over 18 years of age diagnosed with untreated OSA were included. Responses to non-invasive conservative treatment were compared with responses to the primary intervention. Primary outcomes were assessed using the Epworth Sleepiness Scale and/or Functional Outcomes of Sleep Questionnaire (FOSQ). RESULTS A total of eight studies were included in the review. The heterogeneity of the effect was estimated at 89.77%. Six studies compared conservative treatment with CPAP, one with oral appliances, and one with oropharyngeal exercises. Using the Epworth Sleepiness Scale measurements, the standardized difference in the estimated means, based on the random-effects model, was 0.457 (95% CI (1.082 to 0.169)) and the mean result did not differ significantly from zero (z = 1.43; p = 0.153). The conservative therapies assessed in this study improved the subjective quality of sleep, although the post-treatment ESE scores did not show significant results. The reduction in AHI and better outcomes in the evaluated domains, as well as in cognition and mood, were superior in the groups that received CPAP and IOD. CONCLUSION The most commonly used treatments of choice for OSA are invasive, including the use of CPAP, oral appliances, and surgeries, being the most utilized options. This study demonstrated that non-invasive conservative treatments, such as sleep hygiene, yield results as effective as invasive treatments. Further studies are needed to confirm this result and to predict whether invasive treatment can be used as the primary treatment or only as a supplement.

Indications for Dental Specialists for Treating Obstructive Sleep Apnea with Mandibular Advancement Devices: A Narrative Review. Int J Dent 2024; 2024:1007237. [PMID: 38585252 PMCID: PMC10999292 DOI: 10.1155/2024/1007237] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/17/2024] [Revised: 03/20/2024] [Accepted: 03/21/2024] [Indexed: 04/09/2024] Open
Abstract
Obstructive sleep apnea (OSA) syndrome is characterized by repeated airway collapse during sleep. It determines cardiovascular, pulmonary, and neurocognitive consequences and is associated with several daytime and nighttime symptoms that influence the patient's quality of life. The contribution of the dental specialist in the clinical management of OSA patients entails participating in the screening process as diagnostic sentinels and providing adequate treatment using mandibular advancement devices (MADs). Since the treatment of OSA requires a multidisciplinary approach, including different medical specialists, dentists should have a comprehensive understanding of medical and dental factors that influence the strategy and effectiveness of OSA treatment with MAD. Such expertise is crucial in determining the appropriate treatment indications and helps clinicians establish a consolidated position within the multidisciplinary OSA team. In this regard, this review summarizes the evidence of the clinical indications for MAD treatment and provides the dental specialist with helpful information about medical, functional, and other relevant factors that should be considered during diagnosis, treatment plan, and follow-up stages. Information retrieved was organized and discussed, generating specific domains/queries oriented to the clinical management of OSA patients from the clinical perspective of dental specialists.

Abstract
OBJECTIVE To assess which improvements and side effects are considered most important by patients with OSA treated with a MAD. METHODS A specific questionnaire consisting of 20 questions, including 10 questions on improvements and 10 on side effects, was developed and mailed to all subjects (54). RESULTS 42 patients, participated in the survey by answering the questionnaire. The results showed that patients placed greater importance on the positive outcomes of treatment, with the most significant being the reduction in snoring and improvement in sleep quality. On the other hand, the side effects of difficulty speaking with the device, tooth mobility, and foreign body sensation were considered important. CONCLUSIONS The advantages perceived by the patients appear to outweigh the disadvantages, especially the reduction of snoring, increased productivity, and improved social and intellectual life. Most significant side effects are reversible and short-term, while occlusal changes, is not considered important by patients.

Abstract
PURPOSE In France, oral appliances (OAs) are the first-line treatment for moderate and second-line treatment for severe obstructive sleep apnea-hypopnea syndrome. In general, the sleep specialist refers his/her patient to the appliance specialist for the impressions and the fitting. However, is there a relationship between the volume of activity of the appliance specialist and the efficacy of this device? METHODS Our unit includes seven appliance otolaryngology specialists whose activities are highly variable (number of patients varying by a factor of almost 10). Data from a prospective follow-up registry of patients treated with an OA for moderate and severe obstructive sleep apnea-hypopnea syndrome were studied, and differences in outcomes between practitioners in the team were sought. RESULTS Among 859 patients, OAs significantly reduced the apnea-hypopnea index. Even if the patients were not completely comparable from one practitioner to another, there was a significant heterogeneity in efficacy (complete or partial response of the apnea-hypopnea index and failure of OAs) between practitioners (p = 0.0038; 0.0011; 0.0007 respectively), with better results in practitioners with a higher level of OA activity. CONCLUSION The findings suggest that it may be preferable to refer patients to OA practitioners who see a higher volume of patients with moderate or severe obstructive sleep apnea-hypopnea syndrome treated with an OA.

Abstract
STUDY OBJECTIVES Hypoglossal nerve stimulation is an established therapy for sleep apnea syndrome. Whether or not this therapy on snoring and nighttime noise exposure is effective and how strong this effect may be has not been objectively investigated thus far and was the aim of this study. METHODS In 15 participants (14 males; age: 30-72 years; mean: 51.7 years), polysomnography and acoustic measurements were performed before and after hypoglossal nerve stimulation. RESULTS The therapy led to a significant improvement in sleep apnea (apnea-hypopnea index from 35.8 events/h to 11.2 events/h, P < .001). Acoustic parameters showed a highly significant reduction in the average sound pressure level (42.9 db[A] to 36.4 db[A], P < .001), averaged sound energy, A-weighted (LAeq; 33.1 db[A] to 28.7 db[A], P < .001), snoring index (1,068 to 506, P < .001), percentage snoring time (29.7-14.1%, P < .001), and psychoacoustic snore score, the latter being a measure of annoyance due to snoring (47.9 to 24.5, P < .001). CONCLUSIONS This study was able to show for the first time by means of objective acoustic and psychoacoustic parameters that hypoglossal nerve stimulation can not only cause a significant improvement in sleep apnea but also has a positive effect on snoring and thus noise annoyance experienced by the bed partner.

Abstract
OBJECTIVE To evaluate the long-term effectiveness, compliance, and side effects of tongue stabilizing devices (TSDs). METHODS Thirty-nine patients were followed up after 12 and 30 months. The subjective effectiveness was assessed using the Epworth Sleepiness Scale (ESS), the Functional Outcomes Sleep Questionnaire (FOSQ-10), the Chalder Fatigue Scale (CFQ), and a sleep-related quality of life questionnaire (QoL). Compliance and side effects were assessed. RESULTS At 12-months, 35.9% of patients confirmed continuing the therapy, compared to only 15.4% of patients at 30 months. At 30 months, a significant average improvement of ESS (2.0 ± 2.8) was observed compared to baseline levels in six patients. Six patients demonstrated an average increase in blood pressure. The most frequently reported side effects were mouth dryness and excessive salivation. The 3D analysis revealed small tooth movements. CONCLUSION The TSD therapy demonstrated a good long-term subjective effectiveness against OSA but had a relatively low treatment acceptance rate.

Abstract
PURPOSE Mandibular advancement devices (MADs) are a treatment for obstructive sleep apnea (OSA). Titration is a necessary component of proper fitting of MADs, yet little is known about what happens at each step of the titration. The objectives of this study were to determine the clinical and paraclinical evolution of OSA at every mm of MAD advancement. METHODS Volunteers were fitted with MADs set to 50% of maximum advancement. MAD clinical and paraclinical results were recorded at every additional mm-titration, including apnea-hypopnea index (AHI), as well as symptoms of sleepiness and fatigue. RESULTS In 20 volunteers with OSA, the MAD had a significant effect on every polygraphic parameter at the onset of use. The mean AHI with MAD fell by 15.2/h (p < 0.001). The mean Epworth Sleepiness Score and Pichot Fatigue questionnaire with MAD fell by 2.0 (p = 0.0687) and 2.4 (p = 0.1073) respectively. There was no proportionality between clinical gains (drowsiness and fatigue) and AHI improvements. CONCLUSIONS MADs led to a significant improvement in AHI and other polygraphic parameters from the onset of use. The decrease of clinical symptoms (drowsiness and fatigue) was more complex to interpret because of the small decreases observed. The absence of concordance between AHI improvement and clinical symptoms was nevertheless objectively quantified and symptoms were alleviated with advancements. The findings suggest that it may be appropriate to use clinical symptoms as a main aim of titration, since the improvement in AHI is reached at the onset of MAD use.

Abstract
PURPOSE Obstructive sleep apnea (OSA) is frequently treated with continuous positive airway pressure (CPAP) or mandibular advancement devices (MADs). For various reasons, both treatment options are often affected by low adherence. While factors associated with low CPAP adherence are described in the literature extensively, less is known about adherence to MAD therapy. This scoping review aimed to synthesize the body of literature on the factors associated with adherence to MAD treatment. METHODS A systematic literature search was conducted using bibliographic databases PubMed, Embase.com , Web of Science, and the Cochrane Library (Wiley) to identify relevant studies that described factors associated with adherence to MAD in the treatment of OSA or snoring combined with OSA in adults. RESULTS The literature search yielded a total of 694 references. Forty studies were found eligible for inclusion. The literature showed that factors with a possible negative influence on the adherence to MAD treatment are personality aspects; failing effectiveness of MAD; side effects during MAD therapy; using a thermoplastic MAD; dental treatments during MAD therapy; and a poor first experience with the MAD with inadequate guidance by professionals. Factors that may have a positive effect on MAD adherence include effectiveness of therapy, custom-made MAD, good communication skills of the practitioner, early recognition of side effects, stepwise titration of the MAD, and positive first experience with MAD. CONCLUSIONS The knowledge of factors associated with MAD adherence can be used to provide further insight into individual adherence to OSA treatments.

Abstract
INTRODUCTION Oral appliance (OA) therapy in obstructive sleep apnea (OSA) could be a risk factor for normal jaw function, given the prolonged effect of an OA in keeping the mandible in a protruded position away from a normal position. This study aimed to assess changes in symptoms and clinical findings related to jaw function after 1 year of treating OSA with an OA. METHODS In this follow-up clinical trial, 302 patients with OSA were assigned to treatment with either monobloc or bibloc OA. Baseline and 1-year follow-up assessment included using the Jaw Functional Limitation Scale, self-reported symptoms and signs related to jaw function. The clinical examination of jaw function included mandibular mobility, dental occlusion, and tenderness in the temporomandibular joints and masticatory muscles. Descriptive analyses of variables are presented for the per-protocol population. To evaluate differences between the baseline and the 1-year follow-up, paired Student t tests and the McNemar change test was used. RESULTS One-hundred and ninety-two patients completed the 1-year follow-up (male 73%, mean aged 55 ± 11 years). There was no change in the Jaw Functional Limitation Scale score at the follow-up (nonsignificant). The patients described no change in symptoms at the follow-up, except for improvements in morning headache (P <0.001) and increased frequency of difficulties in opening the mouth or chewing on awakening (P = 0.002). Subjectively reported changes in dental occlusion during biting/chewing increased significantly at the follow-up (P = 0.009). CONCLUSIONS No changes in measurements of jaw mobility, dental occlusion, or pain on palpation of the temporomandibular joints or masticatory muscles were seen at the follow-up. Thus, using an OA in treating OSA had limited influence on jaw functions and related symptoms. Moreover, the risk of developing pain and functional impairment in the masticatory system was infrequent, indicating that this treatment is safe and can be recommended.

Abstract
Obstructive sleep apnea (OSA), a form of sleep-disordered breathing, is a significant health concern that leads to substantial morbidity. The collapse or occlusion of the upper airway, which results in reduced or cessation of airflow, is the pathophysiology of sleep apnea. The condition has been attributed to numerous cardiovascular, metabolic, and neuropsychological issues and carries serious health concerns. The ensuing intermittent hypoxia and sleep disruption set off a chain of physiological reactions that aid in developing endothelial dysfunction, systemic inflammation, and oxidative stress. The following line of treatment depends on the appropriate diagnosis of sleep apnea and the underlying cause. The gold standard for diagnosis is polysomnography (PSG), which assesses different physiological parameters during sleep. However, because polysomnography is expensive, patients may use more friendly screening and diagnostic testing kits, like home sleep apnea testing. The clinical symptoms and head and neck history may reveal essential risk factors. The primary objectives of management treatments for sleep apnea are to lessen symptoms, enhance sleep quality, and reduce any health concerns that may be present. It is advised to start with lifestyle changes such as quitting alcohol and sedative use, losing weight, and exercising frequently. The primary treatment for moderate to severe sleep apnea is continuous positive airway pressure (CPAP) therapy, which includes administering pressurized air to keep the airway open while you sleep. Oral appliances, positional therapy, surgery, and complementary therapies are other treatment choices that can be adapted to each patient's needs and preferences. The goal of the review is to evaluate the morphological and functional aspects of the upper airway, including the nose and throat, that influence the onset and severity of OSA. With a focus on the interaction between otorhinolaryngologists, sleep medicine specialists, and other healthcare professionals, we aim to consider how OSA affects otorhinolaryngology-related medical issues, look at any potential reciprocal relationships, and provide a summary of the interdisciplinary management strategy for OSA. We tried to analyse the various surgical and non-surgical therapy options for OSA management available in the otorhinolaryngology field for improving OSA symptoms and results.

Abstract
PURPOSE Mandibular advancement devices (MADs) effectively treat patients with obstructive sleep apnea (OSA). Although the use of morning occlusal guides (MOGs) along with MADs is recommended to prevent dental side effects, there is no evidence to support this. The aim of this study was to evaluate the change in incisor inclination in patients with OSA treated with MADs and MOGs, and to identify its predictive factors. METHODS Patients with OSA who received MAD and MOG therapy and had a reduction in their apnea-hypopnea index greater than 50% were analyzed. Cephalometric measurements were performed at baseline and at a 1-year follow-up or longer to assess the dentoskeletal side effects of MAD/MOG treatment. Multivariable linear regression analysis was used to assess the association between the change in incisor inclination and the independent variables that may cause the observed side effects. RESULTS Among 23 patients enrolled in the study, there was significant upper incisor retroclination (U1-SN: 2.83° ± 2.68°, U1-PP: 2.86° ± 2.46°; P < 0.05) and significant lower incisor proclination (L1-SN: 3.04° ± 3.29°, L1-MP: 1.74° ± 3.13°; P < 0.05). However, no significant skeletal changes were observed. Multivariable linear regression revealed that advancement ≥ 95% of the patients' maximal mandibular protrusion was associated with greater upper incisor retroclination. Increased treatment duration was also associated with increased upper incisor retroclination. No \measured variables were associated with the change in lower incisor inclination. CONCLUSIONS Dental side effects occurred in patients who used MADs with MOGs. The amount of mandibular protrusion by MADs and treatment duration were predictive factors associated with upper incisor retroclination.

A Debate on Surgical and Nonsurgical Approaches for Obstructive Sleep Apnea: A Comprehensive Review. J Pers Med 2023; 13:1288. [PMID: 37763056 PMCID: PMC10533009 DOI: 10.3390/jpm13091288] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/06/2023] [Revised: 08/17/2023] [Accepted: 08/21/2023] [Indexed: 09/29/2023] Open
Abstract
Regular and unobstructed breathing during the night is the prerequisite for an undisturbed and restful sleep. The most prevalent nocturnal breathing disturbance with morbid consequences is obstructive sleep apnea syndrome. The prevalence of obstructive sleep apnea (OSA) is increasing, and a significant number of patients with OSA are undiagnosed. On the other hand, the "obesity epidemic" is a growing concern globally. A sleep test is required to diagnose sleep apnea and to individualize therapy. A multidisciplinary approach is the key to success. This narrative review presents a debate on whether surgery is a friend or a foe in the treatment of sleep apnea. Depending on the type and severity of the apnea, the causal factor, and the presence of obesity and hypercapnia as well as the associated pathologies, the optimal therapeutic method is determined for each individual case. The article concludes that each case is unique, and there is no ideal method. Positive pressure ventilation, although a therapeutic gold standard, has its disadvantages extensively discussed in this paper. Nevertheless, it is necessary prior to any surgical intervention, either for the curative treatment of the causal factor of apnea or for elective surgery for another condition. The anesthetic risks associated with the presence of apnea and obesity should not be neglected and should form the basis for decision making regarding surgical interventions for the treatment of sleep apnea.

Abstract
There is now widespread recognition within the world of sleep medicine of the increasing importance of dental sleep medicine and, in particular, the role of oral appliance therapy (OAT) in the management of adults with obstructive sleep apnoea (OSA). For the purpose of this review, the term OAT refers to a custom-made intra-oral appliance, which acts to posture the mandible in a forward and downward direction, away from its natural resting position. Whilst nasally applied continuous positive airway pressure remains the "gold standard" in nonsurgical OSA management, OAT remains the recognised alternative treatment.This review of OAT aims to provide an evidence-based update on our current understanding of their mode of action, exploring the potential anatomical and physiological impact of their use in preventing collapse of the upper airway; the current clinical practice guidelines, including the recently published National Institute of Clinical Excellence 2021 guidance, in conjunction with the American Academy of Sleep Medicine and American Academy of Dental Sleep Medicine; optimal design features, comparing the role of custom-made versus noncustom OAT devices and the importance of titration in achieving a dose-dependent effect; patient predictors, preference and adherence to OAT; its impact on a range of both patient- and clinician-centred health outcomes, with a comparison with CPAP; the limitations and side-effects of providing OAT; and, finally, a look at future considerations to help optimise the delivery and outcomes of OAT.

Abstract
OBJECTIVES To assess the potential cost-effectiveness of neuromuscular electrical stimulation (NMES) for treatment of mild obstructive sleep apnea (OSA). METHODS A decision-analytic Markov model was developed to estimate health state progression, incremental cost, and quality-adjusted life year (QALY) gain of NMES compared to no treatment, continuous airway pressure (CPAP), or oral appliance (OA) treatment. The base case assumed no cardiovascular (CV) benefit for any of the interventions, while potential CV benefit was considered in scenario analyses. Therapy effectiveness was based on a recent multi-center trial for NMES, and on the TOMADO and MERGE studies for OA and CPAP. Costs, considered from a United States payer perspective, were projected over lifetime for a 48-year-old cohort, 68% of whom were male. An incremental cost-effectiveness ratio (ICER) threshold of USD150,000 per QALY gained was applied. RESULTS From a baseline AHI of 10.2 events/hour, NMES, OA and CPAP reduced the AHI to 6.9, 7.0 and 1.4 events/hour respectively. Long-term therapy adherence was estimated at 65-75% for NMES and 55% for both OA and CPAP. Compared to no treatment, NMES added between 0.268 and 0.536 QALYs and between USD7,481 and USD17,445 in cost, resulting in ICERs between USD15,436 and USD57,844 per QALY gained. Depending on long-term adherence assumptions, either NMES or CPAP were found to be the preferred treatment option, with NMES becoming more attractive with younger age and assuming CPAP was not used for the full night in all patients. CONCLUSIONS NMES might be a cost-effective treatment option for patients with mild OSA.

Abstract
To date, the use of barbed sutures for the surgical management of patients suffering from obstructive sleep apnea and snoring with retropalatal collapse and vibration has significantly increased. A systematic review was carried out, which included clinical studies that used barbed sutures for the treatment of snoring. A qualitative analysis, including six clinical studies, was conducted. Of these, five were studies on barbed pharyngoplasties, and one study involved a minimally invasive surgical procedure. The population consisted of 176 patients, aged 26 to 58 years old. Overall, the included studies showed a mean gain in the snoring Visual Analog Scale of 5.67 ± 1.88, with a mean preoperative value of 8.35 ± 1.17 and a postoperative value of 2.68 ± 1.27. No major complications were described. Given the lack and heterogeneity of this evidence, the conclusion calls for being cautious. In carefully selected snorers and obstructive sleep apnea patients, the use of barbed sutures could represent a valid therapeutic strategy for snoring, ensuring a statistically significant improvement in the subjective parameters. Further studies on a larger scale that assess the role of barbed pharyngoplasties in snoring surgery and more extended follow-up studies are needed in order to confirm these promising results.

Abstract
Background The present study was conducted to develop a standard questionnaire to assess the knowledge and practice of prosthodontists regarding the diagnosis and treatment of obstructive sleep apnea syndrome (OSA). Materials and Methods This study had questionnaire designing and cross-sectional-descriptive phases. Questionnaire domains were identified by a panel of eight experts. The face and content validity of the questionnaire was assessed by experts and four laypeople. The internal consistency reliability of the questionnaire was checked using Cronbach's alpha coefficient. Moreover, its stability was tested using the test-retest method. The questionnaire was completed online by 282 Iranian prosthodontists and the relationship between different variables and scores of knowledge and practice of them with simple and multiple linear regression tests was were analyzed. Results A 32-item questionnaire was designed. The Scale Content Validity Index was >0.8 for clarity, simplicity, and necessity in all domains and the content validity of all questions was above 0.8. As for reliability, Cronbach's alpha coefficient was above 0.7 on average. Faculty members had more knowledge (P = 0.04) and better practice (P = 0.001) compared to others. Prosthodontists who participated in sleep disorders training courses had higher scores in knowledge (P = 0.001) and practice (P = 0.001). Prosthodontists who referred patients to sleep disorders clinics had higher knowledge (P = 0.001) and practice (P = 0.001) than those who did not. Conclusion The questionnaire developed in this study can be considered a comprehensive and executable scale with appropriate reliability and validity. There is a positive relationship between being exposed to information and the level of knowledge and practice of prosthodontists about OSA.

Abstract
This study compared daytime sleepiness and quality of life in OSA patients with healthy controls and compared sleepiness and quality of life in OSA patients before and after long-term treatment with a mandibular advancement device (MAD). A total of 27 OSA patients (18 men, 9 women, mean age 52.3 years) and 32 healthy age- and sex-matched controls (20 men, 12 women, mean age 51.1 years) were included. At baseline and after MAD treatment, daytime sleepiness and quality of life were recorded by the Epworth Sleepiness Scale (ESS) and Short Form-36 questionnaires (SF-36). Daytime sleepiness occurred significantly more often in OSA patients compared to controls at baseline (p = 0.01). The quality of life domains Energy and vitality (p < 0.0001), General perception of health (p = 0.0002), Mental health (p = 0.0031), Social functioning (p = 0.0119), Role limitations due to emotional problems (p = 0.0173) and Physical functioning (p = 0.0226) were significantly poorer in OSA patients compared to controls at baseline. After long-term MAD treatment, daytime sleepiness decreased (p < 0.01) and the quality of life domain Energy and Vitality increased (p < 0.01) in OSA patients compared to baseline. The results of the present study support the relevance of MAD treatment as an effective tool for decreasing daytime sleepiness and increasing the quality of life in OSA patients—also in the long term.

Abstract
BACKGROUND In obstructive sleep apnoea (OSA), treatment with mandibular advancement devices (MADs) reduces patients' Apnoea-Hypopnoea index (AHI) scores and improves their sleepiness and quality of life. MADs are non-invasive alternatives for patients who cannot tolerate traditional continuous positive airway pressure (CPAP) therapy. The variability of responses to these devices makes it necessary to search for predictors of success. The aim of our study was to evaluate the presence of mandibular torus as a predictor of MAD efficacy in OSA and to identify other potential cephalometric factors that could influence the response to treatment. METHODS This was a retrospective cohort study. The study included 103 patients diagnosed of OSA who met the criteria for initiation of treatment with MAD. Structural variables were collected (cephalometric and the presence or absence of mandibular torus). Statistical analysis was performed to evaluate the existence of predictive factors for the efficacy of MADs. RESULTS A total of 103 patients who were consecutively referred for treatment with MAD were included (89.3% men); the mean age of the participants was 46.3 years, and the mean AHI before MAD was 31.4 (SD 16.2) and post- MAD 11.3 (SD 9.2). Thirty-three percent of patients had mandibular torus. Torus was associated with a better response (odds ratio (OR) = 2.854 (p = 0.035)) after adjustment for sex, age, body mass index (BMI; kg/m2), the angle formed by the occlusal plane to the sella-nasion plane (OCC plane to SN), overinjection, and smoking. No cephalometric predictors of efficacy were found that were predictive of MAD treatment success. CONCLUSIONS The presence of a mandibular torus practically triples the probability of MAD success. This is the simplest examination with the greatest benefits in terms of the efficacy of MAD treatment for OSA.

Abstract
The condition of sleep bruxism (SB) is defined by many authors as the body's response to obstructive sleep apnea (OSA). In the conservative treatment of OSA, mandibular advancement devices (MADs) have found their application. The aim of the study iso assess the impact of MADs on the occurrence of episodes and the intensity of OSA and SB. The study sample consisted of eight patients with OSA and SB diagnosed with these conditions on the basis of clinical examinations and polysomnography (PSG). The prospective study was designed to assess the use of MADs for OSA and SB. MADs were prepared for the patients who subsequently underwent control examinations after one week of wear, and another PSG (PSG II) with an MAD was performed in conditions resembling the first qualification examination (PSG I). The same parameters were assessed in both PSG examinations. Following treatment with the MAD, a favorable lowering of the mean values of the examined parameters was observed. The statistically significant differences were demonstrated only for the apnea-hypopnea index (AHI), the oxygen desaturation index (ODI), and the number of apneas and hypopneas, obstructive apneas, apneas in OSA, and phasic episodes of bruxism. The application of MADs in patients with OSA has a beneficial effect on the same manifestations of OSA and SB, even though only the number of phasic episodes of bruxism was statistically significant.

Abstract
Sleep is essential for the proper functioning of all individuals. Sleep-disordered breathing can occur at any age and is a common reason for medical visits. The objective of this consensus is to update knowledge about the main causes of sleep-disordered breathing in adult and pediatric populations, with an emphasis on obstructive sleep apnea. Obstructive sleep apnea is an extremely prevalent but often underdiagnosed disease. It is often accompanied by comorbidities, notably cardiovascular, metabolic, and neurocognitive disorders, which have a significant impact on quality of life and mortality rates. Therefore, to create this consensus, the Sleep-Disordered Breathing Department of the Brazilian Thoracic Association brought together 14 experts with recognized, proven experience in sleep-disordered breathing.

Abstract
Background Both obstructive sleep apnea (OSA) and periodic limb movements of sleep (PLMS) are common in the sleep laboratory. The severity of OSA can be improved by using continuous positive airway pressure (CPAP). However, increasing evidence has shown an elevated periodic limb movement index (PLMI) in patients with OSA who use CPAP, although the pathophysiology is still unknown. This meta-analysis aimed to investigate changes in PLMS after using CPAP and the potential pathophysiology of these changes. Methods Clinical trials in adult humans investigating the comorbidity between PLMS and CPAP were identified and analyzed using random-effects model meta-analysis. Results This meta-analysis included 14 studies comprising 2,938 patients with OSA. The PLMI was significantly increased after using CPAP with a difference in means of 1.894 (95% confidence interval = 0.651–3.138, p = 0.003). Subgroup analysis showed that CPAP was only significantly associated with an increase in PLMI in the patients without PLMS at baseline (p = 0.045) and in those with a baseline body-mass index <30 kg/m2 (p = 0.045). The use of CPAP, apnea-hypopnea index, and arousal index were positively correlated with changes in PLMI. Conclusion These characteristics may serve as qualitative predictive indicators of changes in PLMI after CPAP usage. Further analysis of the quantitative relationships between PLMI and the predictive indicators may be warranted. Trial Registration PROSPERO (registration number: CRD42021252635).

Abstract
Background: Snoring constitutes a worldwide public health concern that may be associated with daytime fatigue, endothelial dysfunction, vascular injury, stroke, cardiovascular diseases, and diabetes among female patients. This study explored the effects of the so-called Lin Oral Appliance (LOA) on Taiwanese adults’ snoring rates.Methods: A time series analysis was conducted to examine the associations between LOAs’ tongue compressors of different lengths, and snoring rates were calculated using the SnoreClock app. The LOA comprises 2 components: custom-made dental braces and tongue compressors of adjustable lengths; different versions had different-length compressors.Results: Our multiple linear regression time-series model revealed the effects of the LOA on snoring rates. The results indicated the following: i) LOA tongue compressor lengths of 1 and 2.5 cm (LOA-1 and LOA-2.5, respectively) were associated with reduced snoring rates; ii) sleep durations of 5.5-7.5 h and daytime sleepiness were associated with increased snoring rates; and iii) among participants with snoring rates above 10%, the snoring rates observed 1-7 days before a given day constituted a significant factor influencing snoring rates on the given day.Conclusions: We discovered that the LOA could reduce snoring rates and that the 2.5-cm compressor length in the LOA produced the best results.

Abstract
Background Obstructive sleep apnea (OSA) is due to the obstruction of the upper airway during sleep. This condition is often associated with multiple symptoms and co-morbidities. There are many treatment options mentioned in the literature to manage OSA, among which interventional option of continuous positive airflow (CPAP) and non-interventional option, i.e., mandibular advancement device (MAD), which is an oral appliance (OA), are the most preferred ones. This study aims to evaluate the efficacy of customized maxillary oral appliances with mandibular advancement devices in moderate OSA patients. Methods A prospective interventional study with a randomized controlled trial will be carried out involving 40 participants (sample size), with an apnea-hypopnea index (AHI) > 15–30, recorded on polysomnography (PSG). Study participants will be randomly divided into the following treatment groups: control group or group subjected to mandibular advancement device (MAD, n=20) and second group subjected to customized maxillary oral appliance (CMOA, n=20). Baseline assessment of apnea/hypopnea index (AHI), oxygen saturation in blood, percentage of rapid eye movement, electroencephalogram, electrocardiogram, oro-nasal airflow via a pressure transducer, and Epworth Sleepiness Scale will be done. Then both study group participants will receive their respective appliances. And after one month and three months of delivery of the appliance, all the parameters, i.e., AHI, oxygen saturation in blood, percentage of rapid eye movement, electroencephalogram, electrocardiogram, oro-nasal airflow via a pressure transducer, and Epworth Sleepiness Scale will be re-evaluated and compared with the baseline measurements. Descriptive and analytical statistics will be done. SPSS (Statistical Package for Social Sciences) Version 20.1 will be used as statistical software. The statistical significance between the two groups after one month and three months will be evaluated at p< 0.05. Discussion We expect, customized maxillary oral appliance to be more efficient in managing moderate OSA, in comparison with MAD. If the hypothesis of the present study is confirmed, then this customized maxillary appliance will be quoted as a “gold standard” for managing moderate OSA.

Abstract
AbstractBackground/purpose Oral appliances (OAs) have been recommended as alternatives for adult patients with obstructive sleep apnea who are intolerant of continuous positive airway pressure therapy. The aim of this study was to explore the effect on snoring rates among adult patients through use of a novel OA termed the Lin OA (LOA, airflow-interference-type nasal congestion relieving and snore-ceasing oral appliance). Materials and methods The LOA consist of two parts: dental braces and a fixed tongue compressor. The compressor lengths range from 0.5 cm to 3.5 cm across versions. Patients used the LOA during sleep and the SnoreClock smartphone application recorded their snoring rates. Results A total of 4920 recordings (4239 recordings from 34 men, 681 recordings from 8 women) were used for the analysis. The recordings were sorted in accordance with the applied length of the LOA tongue compressor (0.5–3.5 cm, LOA-0.5, LOA-1 and LOA-3.5), and participants not using the LOA were denoted as the LOA-0 group. The women had higher snoring rates in the LOA-0, LOA-0.5 to LOA-2 groups, but lower snoring rates in the LOA-3 group than men by the univariate analysis. The snoring rates were significantly reduced by a mean of 5.04% with every 1 cm increase in tongue compressor length. Continuous LOA use resulted in snoring rate reductions of 0.02% per day by the random intercept model of the linear regression. Conclusion Use of this novel LOA may significantly reduce snoring rates by 5.04% with each 1 cm increase in tongue compressor length.

Abstract
Background Obstructive sleep apnoea (OSA) is a sleep-related breathing disorder characterised by the repeated episodic collapse of the upper airway during sleep, resulting in sleep deprivation, giving rise to apnoeas and hypopnoeas. Based on the severity of OSA, there are two primary treatment modalities, continuous positive airway pressure (CPAP) and mandibular advancement appliances (MAA); both are adherence-dependent. MAA is offered to those with mild to moderate OSA and is prescribed as an alternative to patients intolerable to CPAP. However, adherence to MAA treatment is variable and declines over time. Hence, the current study aims to assess the effectiveness of the stage-matched intervention, the Health Action Process Approach (HAPA), on adherence to MAA in patients with OSA. Methods A single-centre randomised clinical trial will be undertaken at Bart’s Health NHS Trust. Fifty-six participants with newly diagnosed OSA are planned to be enrolled in the study and randomised to intervention care (IC) and standardised care (SC) groups. Participants in the SC group will receive routine care whilst participants in the IC group will receive the stage-matched intervention, developed using the HAPA model. Data indicating MAA adherence will be collected both objectively and subjectively, from micro-sensors embedded in the MAA design and sleep diaries, respectively at 3, 6, 18 and 36 months. In addition, a range of questionnaires designed to assess risk perception, outcome expectancy, and self-efficacy (SEMSA) and quality of sleep (PSQI and ESS) and life (EQ-5DL), socio-economic and social support scales will be used. Discussion The currently available treatments for obstructive sleep apnoea depend entirely on the patient’s acceptance and use. There are several factors that affect cooperation and wear for example patients’ awareness of their condition, social support and psychological behaviour. In addition, mood, such as anxiety, stress, and depression, may affect wear. At the same time, we know that interventions involving more education and behaviour approaches can help patients adapt more easily to some treatments. As a result, the present trial aims to explore the potential role of these factors to maximise treatment success and minimise side effects. Trial registration ClinicalTrials.gov NCT04092660.

Abstract
STUDY OBJECTIVES The review aimed to identify the factors influencing adherence to oral appliance therapy in adults with obstructive sleep apnea. METHODS The protocol was initially registered with the International Register of Systematic Reviews (Prospero: CRD42019122615) prior to undertaking a comprehensive electronic search of databases and references without language and date restrictions. Quality assessment was undertaken using the Cochrane Collaboration's risk of bias tool and Quality in Prognosis Studies (QUIPS) tool. RESULTS Studies exhibited low or unclear risk of bias for the domains assessed by the respective quality assessment tools. The influence of independent variables such as disease characteristics, patient characteristics, appliance features, and psychological and social factors on adherence levels was also assessed. There was a total of 31 included studies, which consisted of 8 randomized controlled trials, 2 controlled clinical trial, 7 prospective cohorts, 11 retrospective cohorts, and the remaining 3 studies were a case-series, case-control, and a mixed-methods. All 31 included studies were subject to qualitative analysis, with only 4 studies included in the quantitative analysis. Results of the meta-analysis demonstrated increased adherence with custom-made appliances, with a pooled mean difference of -1.34 (-2.02 to -0.66) and low levels of heterogeneity (I² = 0%). CONCLUSIONS A weak relationship was observed between objective adherence and patient and disease characteristics, such as age, sex, obesity, apnea-hypopnea index, and daytime sleepiness, to oral appliance therapy. Nonadherent patients reported more side effects with oral appliance therapy than users and tended to discontinue the treatment within the first 3 months. Custom-made oral appliances were preferred and increased adherence reported in comparison to ready-made appliances. Further research is imperative to examine the relationship between psychosocial factors and adherence to oral appliance therapy.

Abstract
Obstructive sleep apnea (OSA) is a highly frequent sleep disorder in the middle-aged and older population, and it has been associated with an increased risk of developing cognitive decline and dementia, including mild cognitive impairment (MCI) and Alzheimer's disease (AD). In more recent years, a growing number of studies have focused on: 1) the presence of OSA in patients with MCI or AD, 2) the link between OSA and markers of AD pathology, and 3) the role of OSA in accelerating cognitive deterioration in patients with MCI or AD. Moreover, some studies have also assessed the effects of continuous positive airway pressure (CPAP) treatment on the cognitive trajectory in MCI and AD patients with comorbid OSA. This narrative review summarizes the findings of studies that analyzed OSA as a risk factor for developing MCI and/or AD in the middle-aged and older populations with a special focus on cognition. In addition, it describes the results regarding the effects of CPAP treatment in hampering the progressive cognitive decline in AD and delaying the conversion to AD in MCI patients. Considering the importance of identifying and treating OSA in patients with MCI or AD in order to prevent or reduce the progression of cognitive decline, further larger and adequately powered studies are needed both to support these findings and to set programs for the early recognition of OSA in patients with cognitive impairment.

Abstract
Undiagnosed and untreated obstructive sleep apnea (OSA) is associated with health comorbidities and negatively affects quality of life. Alternative treatments should be considered in patients who are unable to tolerate or benefit from positive airway pressure treatment. When properly indicated, positional devices, oral appliances, airway surgery, and hypoglossal nerve stimulation have been shown to be effective in treating OSA. Hypoglossal nerve stimulation is a successful second-line treatment with low associated morbidity and complication rate.

Abstract
OBJECTIVES/HYPOTHESIS Oral appliances (OAs) are a treatment for obstructive sleep apnea hypopnea syndrome (OSAHS). The main objective of the study was to determine the predictive factors of OA efficacy. The secondary objective was to measure the efficacy rates and determine OAs' tolerance and dropout. STUDY DESIGN Retrospective study. METHODS Efficacy results of the OAs based on the apnea hypopnea index (AHI) reduction, complications, and dropout rates were retrospectively collected from 347 patients with a moderate to severe OSAHS treated by a retention OA. The procedure was entirely performed by otolaryngologists. RESULTS The AHI with OA was more significantly reduced in patients with a higher initial AHI and a higher initial body mass index but reduction was not related to age and not proportional to the degree of mandibular advancement. The 50% AHI reduction rate after OA was 65.2%, the AHI ≤5/hr rate after OA was 26.1%, and the <50% AHI reduction and residual AHI > 10/hr rate was 50.1%. The OA significantly reduced the mean AHI (-14.9/hr, P < .0001). In 7.8% of patients, the AHI increased with OA. Seven patients (1.5%) experienced adverse effects. Thirty-seven (7.8%) patients stopped using OA mainly because of its ineffectiveness. Advancement can be considered beyond the initial maximal advancement. It can be effective sometimes; however, increasing advancement did not significantly reduce AHI. CONCLUSIONS OA is an effective and well-tolerated treatment for moderate to severe OSAHS. This treatment was effective for reduction of the AHI ≥50% in two-thirds of cases studied and it should be considered in more cases. LEVEL OF EVIDENCE 4 Laryngoscope, 131:E2089-E2096, 2021.

Abstract
PURPOSE To assess how expansion sphincter pharyngoplasty (ESP) impacts blood pressure (BP) and health-related quality of life (HRQOL) in hypertensive patients with obstructive sleep apnea (OSA). METHODS Patients were separated into two groups based upon whether or not they adhered to antihypertensive drug regimens. Patients underwent 24-h ambulatory BP monitoring before and at 6 months post-ESP, while clinical BP measurements and HRQOL questionnaires (SF-36) were conducted over the course of 24 months post-surgery. RESULTS We enrolled 62 patients, with 25 and 37 in the medicated and non-medicated groups, respectively. Mean 24-h BP differed significantly, with systolic and diastolic BP (SBP and DBP) decreases of 5.3 mmHg and 2.5 mmHg, respectively (P <0.01). Mean 24-h SBP and DBP decreases in the medicated group were 10.2 mmHg and 4.6 mmHg, respectively (P < 0.001), with significant decreases during the daytime of 8.6 mmHg, 3.0 mmHg, and nighttime of 12.3 mmHg, 7.7 mmHg (P <0.001). In the non-medicated treatment group, 24-h SBP and DBP decreases were 1.9 mmHg and 1.1 mmHg (P < 0.005) with significant decreases in mean nighttime BP values of 3.2 mmHg and 1.9 mmHg (P < 0.001). While pre- and postoperative SF-36 results differed significantly, no differences were observed between the two groups. CONCLUSION ESP decreases BP and improves HRQOL in OSA patients with hypertension, particularly in combination with antihypertensive drugs.

Abstract
BACKGROUND AND OBJECTIVES Treatment effectiveness, in terms of health benefits, is a composite of efficacy and adherence. Oral appliance (OA) usage is mainly based on self-reports, but nowadays, objective adherence monitoring for OAs is available. This study investigated the objective OA adherence and its determinants in obstructive sleep apnoea (OSA) patients. MATERIALS AND METHODS There were 29 subjects who were treated with OA; mean [SD] age 51.4 [11.1]; mean apnoea-hypopnoea index (AHI) [SD] 19.5 [10.0]. Anthropometric and sociodemographic parameters, AHI, daytime sleepiness, snoring, and adverse effects of OA as potential determinants were evaluated. Patients were classified as regular users if they wore OA at least 4 hours nightly 5-7 nights a week. Statistical analyses included the chi-square test, t-test, Mann-Whitney U-test, and linear regression analyses. RESULTS At the 3-month follow-up, 68% of subjects were regular users and at 12-month follow-up, 64%. AHI, sociodemographic parameters, or adverse effects were not associated with OA adherence. Snoring seemed to improve weakly adherence, whereas mandibular retrusion reduced the weekly use, and smoking the nightly use of OAs. LIMITATIONS The follow-up time was short, and there were a relatively small number of patients with obtainable adherence data, therefore it is difficult to establish if OA therapy alone is a successful long-term treatment option for OSA patients. CONCLUSIONS/IMPLICATIONS Adherence to OA therapy is mainly the outcome of patients' subjective comfort in everyday life through eliminating social disturbance of snoring. To best meet a subject's individual treatment need and to prevent suboptimal use of OA, a patient-tailored therapy including digital wear-time documentation is recommended.

Abstract
Objectives
The purpose of this pilot study was to determine whether compliance to auto-adjusting positive airway pressure (APAP) improves with the addition of a mandibular advancement device (MAD). Secondary outcome measures included were APAP pressure, subjective daytime sleepiness, apnea–hypopnea index (AHI), and mask leaks.
Setting and Sample Population
Participants included were diagnosed with moderate-to-severe obstructive sleep apnea (OSA) and became noncompliant to prescribed APAP. Thirteen participants with a mean age of 61.6 years were recruited for this study.
Materials and Methods
All participants were given a MAD to use with their APAP. Parameters measured included APAP pressure, AHI, mask leak reported via ResMed AirViewTM software, and self-reported daytime sleepiness (Epworth Sleepiness Scale [ESS]). A paired two-sample for mean
t
-test was performed to determine significance.
Results
The mean difference of pre- and postintervention APAP compliance was 23.1%, which was statistically significant (
p
= 0.015). The mean APAP air pressures were unchanged. The difference between pre- and postintervention mean ESS scores was 1.4 and was statistically significant (
p
= 0.027). The mean difference between pre- and postintervention AHI values and mask leak showed no significant difference.
Conclusion
This study showed that combination of APAP-MAD therapy, for patients with moderate-to-severe OSA who were noncompliant to APAP use, significantly increased compliance with APAP therapy, and significantly decreased the daytime sleepiness of participants.

Abstract
OBJECTIVE Although oral appliance therapy is considered a validated treatment for obstructive sleep apnea, its therapeutic success varies significantly among patients. Drug-induced sleep endoscopy is often employed in order to identify candidates for upper airway surgery; however, it remains unknown whether its findings can be associated with success of oral appliance therapy. This study tested the hypothesis that drug-induced sleep endoscopy variables can predict the outcome of oral appliance therapy in obstructive sleep apnea patients. METHODS Forty-nine obstructive sleep apnea patients [45 men; mean apnea-hypopnea index 25.3 ± 7.5 events/h; mean body mass index 28.2 ± 3.0 kg/m2] underwent drug-induced sleep endoscopy, followed by a one-month of oral appliance therapy, and subsequently a follow-up polysomnography to assess outcome. RESULTS Thirty-three patients (67.3%) were responders and sixteen were non-responders (32.6%). Non-responders had a higher occurrence of complete or partial circumferential collapse at velum in comparison with responders. Multivariate logistic regression analysis revealed that, among baseline clinical and polysomnographic characteristics and sleep endoscopy findings, the presence of complete circumferential collapse at velum and increased body mass index were the only independent predictors of oral appliance therapy failure. CONCLUSION Drug-induced sleep endoscopy can be used to predict a higher likelihood of success to oral appliance therapy in obstructive sleep apnea patients.

Abstract
INTRODUCTION Mandibular appliances are a treatment option for obstructive sleep apnea. There are many designs, but in the literature they tend to be grouped into a single entity without considering that efficiency, tolerance, compliance, or side effects are inherent in the design of each of them. A more detailed literature review is therefore warranted for the reader who wants to understand the relative effectiveness of each appliance. STATE OF KNOWLEDGE We conducted a literature search using the "oral appliance" and "obstructive sleep apnea" criteria on Pubmed, Embase and Cochrane. This allowed us to compare outcome parameters by appliance class and to highlight the rare studies comparing different appliances. CONCLUSIONS Mandibular appliances are not a homogeneous entity. Common use includes only appliances designed for propulsion (with rods and jacks) and retention. However, the few comparative studies available do not identify which are the most effective types or the types with an optimal efficacy/tolerance ratio. PERSPECTIVES Further appliance comparison studies are needed to determine the most effective type or with an optimal efficacy/tolerance ratio.

Are annoyance scores based on sound pressure levels suitable for snoring assessment in the home environment? Sleep Breath 2020; 25:417-424. [PMID: 32462274 PMCID: PMC7987700 DOI: 10.1007/s11325-020-02108-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/13/2020] [Revised: 04/14/2020] [Accepted: 05/15/2020] [Indexed: 11/29/2022]
Abstract
Purpose An objective statement about the annoyance of snoring can be made with the Psychoacoustic Snore Score (PSS). The PSS was developed based on subjective assessments and is strongly influenced by observed sound pressure levels. Robustness against day-to-day interfering noises is a fundamental requirement for use at home. This study investigated whether or not the PSS is suitable for use in the home environment. Methods Thirty-six interfering noises, which commonly occur at night, were played in the acoustic laboratory in parallel with 5 snoring sounds. The interfering noises were each presented at sound pressure levels ranging from 25 to 55 dB(A), resulting in 3255 distinct recordings. Annoyance was then assessed using the PSS. Results In the case of minimally annoying snoring sounds, interfering noises with a sound pressure level of 25 dB(A) caused significant PSS changes from 40 to 55 dB(A) for annoying snoring sounds. If the interfering noise was another snoring sound, the PSS was more robust depending on the sound pressure level of the interfering noise up to 10 dB(A). Steady (no-peak) interfering noises influenced the PSS more strongly than peak noises. Conclusions The PSS is significantly distorted by quiet interfering noises. Its meaningfulness therefore depends strongly on the acoustic environment. It may therefore be assumed that scores dependent on sound pressure level are suitable for measurements when there is minimal ambient noise, as in the sleep laboratory. However, for measurements where noise is incalculable, as in the home environment, interfering noises may distort the results.

Abstract
Purpose It is not easy to assess how severe and annoying a patient’s snoring is. Solid parameters are lacking; snorers cannot deliver a reliable self-assessment and it is uncertain whether bed partners’ statements can be relied upon. The purpose of the present study was therefore to investigate whether and how well snoring assessment based on acoustic parameters and bed partners’ reporting agree. Methods In a double-blind, placebo-controlled study on snoring treatment, several acoustic parameters [snoring index (SI), percentage snoring time (ST), sound pressure level, sound energy, loudness, psychoacoustic annoyance and psychoacoustic snore score (PSS)] were measured in 18 subjects during 24 polysomnographies. Bed partners also assessed snoring annoyance and loudness as well as treatment outcome. Results No correlation was found between the subjective annoyance caused by snoring and the acoustic parameters. Regarding perceived loudness, there was a moderate, significant correlation with loudness (N5) and PSS over the hour with the highest SI. SI, ST, LAeq and maximum sound pressure level dB(A)max showed no significant correlation. After the intervention only mean sound energy LAeq over the entire night showed a significant correlation (rs = 0.782; p = 0.022) with bed partners’ assessments. However, this result was not confirmed in the second control night. Conclusions The non-existent or only weak correlation between bed partners’ ratings and objective parameters indicate that snoring severity should be evaluated with caution. Neither acoustic parameters, at least for one measurement over just one night, nor bed partners’ ratings should be used as the sole basis for snoring assessment.

Abstract
INTRODUCTION This 10-year prospective cephalometric study evaluates the influence of a mandibular protruding device (MPD) in people with obstructive sleep apnea and snoring. METHODS A baseline study population of 77 people was followed biennially. After 10 years, 65 people (45 MPD users and 20 stopped-MPD users) were reexamined. At baseline and after 10 years, a lateral cephalogram was taken in the upright position. RESULTS MPD users showed significant changes in all cephalometric variables except for maxillary protrusion. The maxillary incisors were retroclined by a mean -4.2° (standard deviation [SD] 3.95; P <0.001), mandibular incisors were proclined by a mean 3.2° (SD, 5.02; P <0.001), and SNB was reduced by a mean -0.6° (SD 1.41; P = 0.01). In those who had stopped MPD use, these initial cephalometric values were retained. Significant changes in decreased overjet and overbite were seen in the MPD group but not in the MPD-stopped group. The length of the mandible (Cd-Pg) increased by a mean of 5.1 mm (SD 6.78; P <0.001) and 6.1 mm (SD 5.99; P <0.001) in MPD and MPD-stopped groups, respectively. The hyoid bone-mandibular plane distance (hy-ML) increased by a mean of 3.3 mm (SD, 2.90; P <0.001) and 3.8 mm (SD 3.67; P = 0.001) in MPD and MPD-stopped groups, respectively. CONCLUSIONS Long-term nocturnal MPD use causes retroclination of the maxillary incisors and proclination of the mandibular incisors with consequent decreased overjet and overbite. Both MPD and MPD-stopped users obtained increased mandibular length and lower position of the hyoid bone, which can be a normal physiological change with age.

Abstract
PURPOSE To compare the efficacy of tongue-retaining device (TRD) versus continuous positive airway pressure (CPAP) for treatment of obstructive sleep apnea (OSA). STUDY DESIGN Randomized crossover study. SUBJECTS AND METHODS Thirty-six patients with a mean age of 52.7 ± 10.6 years were enrolled. Inclusion criteria were age ≥ 18 years, apnea-hypopnea index (AHI) ≥ 5 events/h, and minimum oxygen saturation (SO2) ≥ 70% from polysomnography (PSG). Exclusion criteria were severe periodontal disease, unstable cardiopulmonary or neurological diseases, and/or total sleep time < 2 h. A 1-week wash-in period was followed by questionnaires and randomization into two groups: TRD/CPAP and CPAP/TRD (18 patients each). After 3 weeks of intervention, questionnaires were re-administered and WatchPAT was performed. After a 1-week wash-out period, patients were switched to the other treatment. Primary outcome was AHI. Secondary outcomes were SO2, Functional Outcomes of Sleep Questionnaire (FOSQ), and Epworth Sleepiness Scale (ESS) scores, treatment side effects, and adherence. RESULTS Nine patients withdrew, so 27 patients were included in the final analysis. Mean AHI decreased from 38.7 ± 24.0 to 2.5 ± 0.5 and 12.7 ± 2.6 events/h for CPAP and TRD, respectively (95% confidence interval of mean differences 4.65-15.62; p < 0.001). There was no significant difference in ESS and FOSQ scores between treatments. Common adverse effects were drooling, tongue numbness, and pain for TRD; and nasal blockage, mask compression, and difficult portability for CPAP. CONCLUSIONS CPAP was superior to TRD for resolving PSG parameters; however, both similarly improved QOL and daytime sleepiness. TRD might be considered a short-term alternative treatment for OSA.

Abstract
A fully-implantable device for treating obstructive sleep apnea (OSA) is conceptually suggested using soft palate stimulation. In this research, two in vivo studies were conducted to demonstrate electrical and physical feasibilities of the suggested device. First, electrical stimulation was delivered to the soft palate of a rabbit using a stimulator ASIC. The stimulation frequencies were swept from 20 Hz to 200 Hz to find out the appropriate parameter. Also, threshold level of the current pulse was evaluated to be 1.10 mA with an observance of a C-arm fluoroscopy. Second, a mock-up was fabricated with liquid crystal polymer (LCP), reflecting dimensions of the suggested device. The mock-up was inserted toward the soft palate of a rabbit by incising the hard palate in a lateral direction. After the mock-up was inserted, protrusion of the device was not detected and the subject stayed alive for at least a month at the time of this writing. Finally, several discussions on the palatal implant fabrication with LCP are presented.

Abstract
STUDY OBJECTIVES The modified jaw-thrust maneuver (MJTM) during drug-induced sleep endoscopy (DISE) is known to predict the treatment effect of mandibular advancement devices. However, its effect on the depth of sedation and potential to provoke arousal by awakening patients during the maneuver has not been studied so far. This study investigated the effect of the MJTM on the depth of sedation during DISE. METHODS Forty patients on whom the MJTM was performed during DISE were included. The effect of the maneuver was evaluated at the levels of the velum, lateral wall of the oropharynx, base of the tongue, and epiglottis. Obstruction was defined as the collapse of the upper airway exceeding 75%, and improvement with the MJTM was defined as the widening of the upper airway by more than 50% during the maneuver. A bolus injection of midazolam was used to induce sedation and control the depth of sedation (bispectral index value of 60 to 80). RESULTS Obstructions were present in the velum of all patients, lateral wall of the oropharynx of 13 patients, base of the tongue of 28 patients, and epiglottis of 6 patients. After the MJTM, improvement of the obstruction was observed in 57.5%, 61.5%, 82%, and 66.7% of patients with velum, lateral wall of the oropharynx, base of the tongue, and epiglottis obstructions, respectively. An increase in the bispectral index value of more than 20 was observed in 8 patients. Four patients awakened during the procedure. CONCLUSIONS The MJTM significantly relieved obstruction during DISE, especially at the base of the tongue. However, this might have been caused by an increase in the degree of awakening during the maneuver. Therefore, MJTM's effect on the depth of sedation may help in improving the degree of airway obstruction.

Abstract
Obstructive sleep apnea (OSA) is defined as episodes of upper airway obstruction occurring during sleep. Conservative treatment of OSA consists of continuous positive airway pressure (CPAP). An alternative treatment in mild-to-moderate OSA could be the use of intraoral mandibular advancement devices (MAD). The aim of this study was to evaluate therapeutic efficacy of MAD in OSA patients intolerant to CPAP. The study group included 8 patients, who fulfilled specific inclusion criteria during a dental examination, out of the 30 CPAP intolerant patients who were referred for the possible use of MAD. The selected patients used MAD for 30 days and then switched to CPAP for 10 days to compare the effectiveness of both treatment methods. They had 3 polysomnographic (PSG) examination: baseline before treatment, and at the end of MAD and CPAP. We found that either treatment method resulted in comparable symptomatic improvements in OSA patients. In detail, the apnea-hypopnea index decreased, along with the overall number of obstructive, central, and mixed apneic episodes during sleep time. The mean arterial oxygen saturation (SaO2) improved and the minimum SaO2 level noted during night time got enhanced. Differences in the sleep apnea indices after MAD and CPAP treatments were insignificant, but there was a consistent impression that CPAP was superior to MAD as it tended to improve symptoms to a somehow greater extent. We conclude that MAD is a sufficiently effective treatment alternative for OSA patients who are intolerant to CPAP or in whom CPAP therapy fails.
