Background/Aim. Obstructive sleep apnea (OSA) is one of the most prevalent sleep disorders. It is recognized as a serious risk factor for car and workplace accidents due to daytime sleepiness, and factor for coronary heart diseases and stroke. The aim of this study was to examine the effectiveness of oral appliances for mandibular advance in treating mild to moderate OSA. Methods. A total of 15 patients were included in this study, all diagnosed with mild or moderate OSA. Oral appliances were custom made for each patient in protrusive position at 50% of maximum mandibular advancement. The patients were given instructions not to sleep on their backs and avoid alcohol consumption during the study as these are the factors that can contribute to symptoms progression. Results. Complete and partial treatment success was achieve in 14 of the patients. Apnea-hypopnea index values were significantly lower (p < 0.05) at the end of a 6-month observation period compared to those at the treatment beginning. A great improvement in symptoms was observed, with daytime sleepiness index values significantly reduced already within the first month of the treatment. Conclusion. Treatment of obstructive sleep apnea with oral appliances has proven successful. Patients were comfortable using oral appliances and were ready to wear them for prolonged period of time. Use of oral appliances is very common in the world and should not be discarded. They are also very comfortable, practical and affordable comparing to continuous positive airway pressure (CPAP) apparatus, not to mention surgery. Use of oral appliances is safe and very well tolerated, and ought to be offered to patients with OSA.

This systematic review clarifies the amount of effective protrusion in mandibular advancement devices of oral appliances required for obstructive sleep apnea (OSA). The systematic review adhered to the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines. Review Manager 5 and GRADEpro were used to combine trials and analyze data. The present review included three studies. In mild to moderate OSA cases, measured using the apnea–hypopnea index (AHI), 50% protrusion was more effective than 75% protrusion. However, 75% protrusion was more effective for severe cases. Sleep stage, Epworth Sleepiness Scale (ESS), snoring index, and side effects significantly differed between the groups. Additionally, 75% protrusion was more effective (AHI: 0.38, 95% CI: −0.89 to 1.65, p = 0.56; sleep stage 3: −1.20, 95% CI: 9.54–7.14, p = 0.78; ESS: 1.07, 95% CI: −0.09 to 2.24, p = 0.07; snoring index: 0.09, 95% CI: 0.05–0.13, p < 0.05; side effects: RR: 1.89, 95% CI: 0.36–9.92, p = 0.45). As per the AHI, 75% protrusion was effective in severe cases, whereas 50% protrusion was effective in moderate cases. Analysis of different surrogate outcomes indicated that 75% protrusion was more effective. Further, well-designed, larger trials should determine the benefits for patients. Additionally, investigations of adherence and side effects with long-term follow-up are needed.

A titratable thermoplastic mandibular advancement devices (MAD) is clearly an effective treatment option in some patients with obstructive sleep apnea (OSA). Determining which patients may be more likely to respond to treatment with thermoplastic MADs and to adhere to treatment would be of obvious clinical relevance. This was an experimental descriptive study (N = 60). Patients with OSA were instructed to wear a titratable thermoplastic MAD for 3 months. Treatment success was defined as a ≥50% reduction from baseline in the apnea-hypopnea index (AHI) or AHI <10 when wearing MAD. Adherence was defined as MAD use ≥5 nights/week. Treatment was successful in 66.7% of patients and 60.0% were adherent. All Polysomnographic parameters and visual analogue scale scores (sleep quality, snoring, waking refreshed) were significantly improved after treatment. The patients in whom treatment failed had significantly higher neck circumferences (39.3 cm vs. 37.5 cm, p = 0.014), higher baseline AHI values (26.6 vs. 18.0, p = 0.016), and smaller AHI reduction (-31.8 vs -53.1, p < 0.001) than those in the group in whom treatment succeeded. There were no significant differences in Polysomnographic, cephalometric, or visual analogue scale measures between patients for whom treatment was and was not successful, regardless of baseline values or the change rates after the MAD was placed. Titratable thermoplastic MADs can improve indicators of sleep quality, even in patients in whom treatment is considered to have failed.

Objective: To evaluate the outcomes of custom-made oral appliances (OAs) for the treatment of obstructive sleep apnea (OSA) in Thai patients. Materials and Methods: A retrospective review of polysomnography (PSG) results and relevant information, including patient characteristics, visual analog scale (VAS) of sleep-associated symptoms, and Epworth Sleepiness Scale (ESS) of patients treated with an OA between January 2010 and January 2018 was done at Siriraj Hospital, Thailand. Inclusion criteria were OSA patients aged 18 years or older who underwent diagnostic and therapeutic PSG with a custom-made OA. Exclusion criteria were patients who were lost to follow-up or had incomplete PSG data. Results: Sixty-seven OSA patients were recruited. The median apnea-hypopnea index (AHI) was significantly decreased from 16.5 (11.5, 27.8) to 5.1 (2.8, 11.3) events per hour (p<0.001) and the median minimal oxygen saturation increased from 82.0 (77.0, 86.0) to 87.0 (80.0, 90.0) with OA treatment (p<0.001). ESS scores decreased from 9 (6, 13) to 7 (4, 9) (p<0.001) and the VAS of snoring loudness and frequency as rated by family members or bed partners decreased from 6 (4, 7.5) to 3.3 (2, 5) and from 5.5 (3.2, 7.6) to 3.4 (2, 5.3), respectively (p<0.001). Forty-one patients (61%) had a 50% reduction of AHI, and an AHI of less than 15 events per hour after treatment, which were considered good responses. Common adverse effects of the treatment included temporomandibular joint discomfort, dry mouth, excessive salivation, gingival pain, and toothache, but these occurred to only a mild-to-moderate degree and were tolerable. Conclusion: Custom-made OA is an effective alternative treatment for OSA in selected Thai patients, particularly for those with a mild-to-moderate degree.

Oral appliance therapy is increasingly prescribed as a non-invasive treatment option for patients diagnosed with obstructive sleep apnea. The custom-made titratable mandibular advancement devices (MAD) are the recommended type of oral appliances. Mandibular advancement devices are efficacious in reducing the severity of obstructive sleep apnea, however, only to a lesser extent than standard therapy using continuous positive airway pressure (CPAP). Although oral appliance therapy is known to reduce the severity of obstructive sleep apnea in most of the patients, one out of three patients still show negligible improvement under MAD therapy. Therefore, the selection of the appropriate candidates for this therapy is imperative and several upfront prediction tools are described. Overall, the health outcome of mandibular advancement device therapy is similar to that of CPAP, probably due to the inferior compliance of CPAP compared to MAD therapy, resulting in similar clinical effectiveness.

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.

Background. The occurrence and severity of excessive daytime sleepiness (EDS) vary considerably among obstructive sleep apnea (OSA) patients. This study was designed to investigate the characteristics of EDS and identify its contributing factors in OSA patients. Methods. This was a cross-sectional study from a tertiary medical center in China. A total of 874 consecutive patients with newly diagnosed OSA were included. Subjective daytime sleepiness was assessed with the Epworth Sleepiness Scale (ESS). The subjects were assigned to the non-EDS group (582 patients), mild to moderate EDS group (227 patients), and severe EDS group (65 patients) according to the ESS scores. The clinical features and polysomnographic parameters were acquired and analyzed to identify the differences between groups and the determinants of EDS. Results. The age of patients with severe EDS (49.5 ± 11.3) was slightly greater than that of patients with mild to moderate EDS (44.5 ± 10.2) (p<0.05) and non-EDS patients (45.2 ± 12.0) (p<0.05). Body mass index (BMI) was highest in the severe EDS group (29.1 ± 3.6 kg/m2) (p<0.0001), intermediate in the mild to moderate EDS group (27.9 ± 3.3 kg/m2), and lower in the non-EDS group (26.8 ± 3.3 kg/m2). Logistic regression analysis showed waist circumference, memory loss, work/commute disturbances, and sleep efficiency were independently associated with mild to moderate EDS, and the microarousal index, apnea-hypopnea index (AHI), and saturation impair time below 90% were independent contributing factors of mild to moderate EDS. Meanwhile, age, neck circumference, gasping/choking, memory loss, work/commute disturbances, and sleep latency were independently associated with severe EDS, and the AHI and mean SpO2 were independent contributing factors of severe EDS. Conclusions. OSA patients with various severities of EDS are more obese and have more comorbid symptoms compared to patients without EDS. Sleep fragmentation, respiratory events, and nocturnal hypoxia may be predictors of EDS. Comprehensive consideration of demographic, clinical, and polysomnographic factors is required when evaluating OSA patients.

ABSTRACT Purpose: to compare nasal geometry between two groups of patients with different degrees of obstructive sleep apnea and to correlate apnea-hypopnea index, apnea severity and degree of daytime sleepiness with nasal areas and volume. Methods: a total of 20 adults (15 women and 5 men, mean age of 52.0±11.4 years old) without nasal obstruction were submitted to polysomnography. The subjects were divided into two groups: a) 10 individuals without apnea or with mild-grade apnea; b) 10 with moderate or severe apnea. Nasal geometry was evaluated by acoustic rhinometry. The volume, comprising the distance from the nasal valve to the posterior part of the middle nasal turbinate, and the three sectional areas corresponding to nasal valve, anterior part of the inferior nasal turbinate and posterior part of the inferior nasal turbinate, were considered. The Shapiro-Wilk, Mann-Whitney, Student’s t tests for independent samples and Spearman’s correlation coefficient were used for the analysis, with a significance level lower than 5%. Results: group 2 presented lower values in the area corresponding to the nasal valve (on the right), and higher values in the nasal turbinate areas. There was no correlation between the drowsiness scale and nasal areas and volumes. Conclusion: the area of the nasal valve was unilaterally smaller in the group with moderate and severe apnea. There was no correlation between volumes and nasal areas and excessive daytime sleepiness.
