Methods: A prospective single blinded randomised controlled trial was conducted in the otolaryngology department of a UK teaching hospital (Exeter). 127 adult patients with a history of simple snoring or sleep apnoea were recruited. 93 patients completed the study. Patients were excluded because of severe sleep apnoea (apnoea index > 40), or morbid obesity (BMI > 40). The study group completed a self-guided treatment programme of singing exercises contained on a 3CD box set, performed for 20 minutes daily. Outcome measures included the Epworth Sleepiness Scale, the SF-36 generic quality of life assessment tool, visual analogue scales (VAS range 0-10) of snoring loudness and frequency, and visual analogue scale of compliance (for intervention group). Results: The Epworth scale improved significantly in the experimental group compared to the control group (difference -2.5 units;95% CI -3.8 to -1.1;p = 0.000). Frequency of snoring reduced significantly in the experimental group (difference -1.5;95% CI -2.6 to -0.4;p = 0.01), and loudness of snoring showed a trend to improvement which was non-significant (difference -0.8;95% CI -1.7 to 0.1;p = 0.08). Compliance with exercises was good;median 6.6 (quartiles = 4.1, 8.3). Conclusions: Improving the tone and strength of pharyngeal muscles with a 3 months programme of daily singing exercises reduces the severity, frequency and loudness of snoring, and improves symptoms of mild to moderate sleep apnoea.展开更多

Appropriate diagnosis is of importance due to detrimental effects of OSA. Polysomnography is considered the gold standard for the diagnosis of OSA. However, it is impractical for several reasons and this is why other tests have been developed as alternatives to formal polysomnography(PSG) for the assessment of children with snoring. In this mini-review basic features of PSG as well as alternative tests are presented and future perspectives are provided in addition to current guideline for the diagnosis and monitoring of childhood snoring. The aim of this review is to highlight briefly currently developed technologies that seem promising for the evaluation of snoring.展开更多

An adaptive least mean square(LMS)algorithm optimized for different kinds of snore signals is introduced and theoretically analyzed. Also, a residual noise masking approach is proposed to further reduce the effect of the snore noise without interfering with the LMS algorithm. Computer simulations followed by real-time experiments are conducted to demonstrate the feasibility of the snore ANC systems based on a pillow setup. For the optimum effect based on the characteristics of human hearing, the performance of the proposed approach is evaluated by using the multi-channel feedforward ANC systems based on the filtered-X least mean square(FXLMS) algorithm.Compared with a traditional headboard setup for snoring noise control, the proposed snore ANC systems optimized for ear field operation yield much higher noise reduction around the ears of the snorer's bed partner.展开更多

Mandibular advancement devices (MAD) are proven to be efficient in treating mild to moderate sleep apnea and snoring. We examined patients who had been treated in Community Dental Care with a titrable Herbst-type MAD. The aim of the study was to evaluate the quality of sleep based on self report. Methods: A questionnaire was mailed to patients (n = 184) who had received treatment for OSA or snoring between 2007 and2010 inthe Helsinki Health Centre Oral Care Unit. The patients were referred to the clinic for primary treatment, or because another treatment modality had failed. Results: Of the respondents (n = 142, 78.4%), OSA had been diagnosed in 74%, while the MAD was applied for snoring to the remaining. Among all respondents, 78.4% had worn the MAD at least three nights per week. With the MAD in situ, sleep was felt significantly less disrupted (p < 0.001) and more restorative (p < 0.001), and snoring was markedly reduced (p < 0.001). Daytime tiredness was also markedly less frequent (p < 0.001). Conclusions: Treatment with a MAD improved perceived sleep quality and awoke alertness in mild and moderate OSA patients and in snorers. This study supports such treatment to be initiated and monitored in community dental care.展开更多

Although not every snorer has OSA or vice-versa, many studies attempt to use snoring sounds for classification of people into two groups of OSA and simple snorers. This paper discusses the relationship between snorers’ anthropometric parameters and statistical characteristics of snoring sound (SS) and also reports on classification accuracies of methods using SS features for screening OSA from simple snorers when anthropometric parameters are either matched or unmatched. Tracheal respiratory sounds were collected from 60 snorers simultaneously with full-night Polysomnography (PSG). Energy, formant frequency, Skewness and Kurtosis were calculated from the SS segments. We also defined and calculated two features: Median Bifrequency (MBF), and projected MBF (PMBF). The statistical relationship between the extracted features and anthropometric parameters such as height, Body Mass Index (BMI), age, gender, and Apnea-Hypopnea Index (AHI) were investigated. The results showed that the SS features were not only sensitive to AHI but also to height, BMI and gender. Next, we performed two experiments to classify patients with Obstructive Sleep Apnea (OSA) and simple snorers: Experiment A: a small group of participants (22 OSA and 6 simple snorers) with matched height, BMI, and gender were selected and classified using Na?ve Bayes classifier, and Experiment B: the same number of participants with unmatched height, BMI, and gender were chosen for classification. A sensitivity of 93.2% (87.5%) and specificity of 88.4% (86.3%) was achieved for the matched (unmatched) groups.展开更多

The patients with snoring should be evaluated for nasal airway obstruction. In this study, the upper air way tract was characterized in snoring patients and compared with none snoring using a quantify method for the corresponding anatomic upper air way (UA) parameters examined by Computerized Tomography (CT). Two hundred Asian patients undergoing CT scanning for head and neck were included and were divided into two groups (snoring group [n = 127] and non-snoring group [n = 73]) (mean age: 44.8 ± 15.9 years and 26.2 ± 7.0). Total 8 parameters were measured on sagital reconstructed CT images for each subject. The differences in neck circumference (NC), linear distance between mandibular plane and hyoid bone (Mp-H), upper airway length (UAL), the maximum thickness of the soft palate (SP max), soft palate length (PNS-U), linear distance between anterior and posterior nasal spine (ANS-PNS), retroglosal width (RS), retroplatal width (RP) between the snoring and non-snoring groups were compared statistically using independent sample t-test. Results showed that the NC, UAL, and SP max were significantly higher in snoring group;however RP was found to be significantly lower. Inferior positioning of hyoid bone gives longer measurement for MP-H. In snoring group UAL was found to be significantly different at p ≤ 0.000 between the two genders. All the measured variables showed no significant differences in respect to age. UA CT quantitative features play an important role in the characterization of the anatomy and are compared between snoring patients and non-snoring subjects.展开更多
