“…PSG has been applied in previous investigations to assess the effects of mechanical nasal dilation on snoring [8±11, 20]. HO È IJER et al [8] studied the effects of Nozovent TM , an internal nasal dilator, on snoring and obstructive sleep apnoea in a group of 11 patients, using a randomized but not controlled study design. They observed that the use of Nozovent TM was associated with a significant decrease in apnoea frequency and snoring noise, expressed as number of epochs with snores of equal energy levels above 55 or 60 dB.…”

“…With the introduction of mechanical nasal dilators in the last decade, an alternative treatment option has become available in addition to surgical or pharmacological approaches. While at first beneficial results with mechanical dilation of the nose were reported [7,8], other investigators found that this particular treatment had limited or no benefits on snoring characteristics [9±11].…”

Chronic rhinitis patients often suffer from unrefreshing sleep and snoring, related to increased nasal resistance to airflow. Previous trials based on subjective assessment of snoring have demonstrated beneficial effects of Breathe RightTM (BRTM), a noninvasive external nasal dilator. Polysomnography (PSG) was applied to objectively assess the effects of BRTM on snoring. Twelve nonobese chronic rhinitis patients participated in the present study, which had a randomized, placebo‐controlled design. The presence of snoring and the absence of sleep apnoea was demonstrated during a baseline overnight sleep study. Patients were then randomized for placebo or true nasal dilator treatment, which was also assessed by overnight PSG. The use of BRTM had no effect on sleep quality, arousal‐index apnoea‐hypopnoea‐index or snoring loudness. Snoring frequency was significantly lowered by BRTM (173±29 snores·h‐1), compared with placebo (258±34 snores·h‐1; p=0.016). The results support the hypothesis that Breathe RightTM is effective in reducing the amount of snoring in patients with chronic rhinitis. This objective finding is in line with some other reports on subjective improvement of snoring, based upon the judgement of bedpartners.

“…74 Other Therapies Common forms of self-help recommended as adjunctive treatments to primary therapy with CPAP include weight loss (if applicable, including bariatric surgery in the morbidly obese), avoidance of alcohol and sedatives, sleeping in a more upright position, and the use of nasal dilation clips. 25,75,76 In addition, supplemental oxygen may be used as an adjunct to other therapies for OSA; however, it does not address morbidities associated with this sleep disorder in the same way as CPAP treatment, and it has not yet been rigorously studied in randomized trials. 77 For these reasons, supplemental oxygen is not indicated as a primary treatment for OSA.…”

Objective: This review aims to impart information regarding recognition of obstructive sleep apnea (OSA) and associated excessive sleepiness (ES) in the primary care setting in order to provide optimal care to patients with this common but serious condition. This review will also discuss the prevalence and treatment of depression in patients with OSA.Data Sources: A MEDLINE search of articles published between 1990 and 2008 was conducted using the search terms obstructive sleep apnea AND excessive sleepiness, obstructive sleep apnea AND depression, and obstructive sleep apnea AND primary care. Searches were limited to articles in English concerned with adult patients.Study Selection: In total, 239 articles were identified. Articles concerning other sleep disorders and forms of apnea were excluded. The reference lists of identified articles were searched manually to find additional articles of interest.Data Synthesis: Primary care physicians can aid in the diagnosis of OSA and associated ES by being vigilant for lifestyle and physical risk factors associated with this condition. In addition, primary care physicians should maintain a high level of clinical suspicion when presented with illnesses that are commonly comorbid with OSA, such as psychiatric disorders and depression, in particular. Conversely, assessment of patients with OSA for common comorbidities may also improve a patient's prognosis and quality of life.Conclusions: Primary care physicians play a vital role in recognizing OSA and ES. These clinicians are crucial in supporting their patients during treatment by ensuring that they have clear, concise information regarding available therapies and the correct application and maintenance of prescribed devices.

“…Without this muscle tension any relaxed tissue collapses into the throat where it may cause turbulence and vibration (snoring) or completely block off the airway (sleep apnea) 9 -11 . Snoring is known to worsen with age, gender, obesity (collar size, Body Mass Index), alcohol ingestion, cigarette consumption, and nasal obstruction 5,[12][13][14][15][16][17] , and it results in significant social disability, contributing to relationship disharmony, and social ostracism 18 . In addition, snoring has been implicated in the etiology of more morbidity, such as: hypertension, ischemic heart disease, cerebrovascular accident, increased morbidity and mortality from road traffic and work related accidents [19][20][21] .…”

“…The other approach aims to affect the tone and/ or size of the soft palate and/or upper throat. The treatment could also be divide in: nonsurgical (weight reduction, reduction of alcohol intake, pharmacological treatment of coincident nasal obstruction [13][14][15][16] , Continuous Positive Airway Pressure (CPAP) appliance 23 , Mandibular Advancement Oral Appliances 24,25 , and surgical (surgery for coincident nasal obstruction 26 , uvulopalatopharyngoplasty 27,28 , palatal stiffening techniques [29][30][31][32][33][34] , palatal shortening techniques) [35][36][37] . Based on these approaches, methods to increase muscle tonus of upper airway, such as singing exercises, miofunctional therapy, instrumental therapy (music), and electrical stimulation have been used as an alternative treatment for snoring.…”

-Background:Snoring is the noise caused by vibration during the in-breath; and which structure actually vibrates depends on many factors. Objective: The treatment of snoring with methods to increase muscle tonus of upper airway has been controversial, and poorly reported, thus a review of evidence is necessary to evaluate the effectiveness of these methods. Method: A review of randomized or quasi-randomized, double blind trials on snoring treatment that have employed any method to increase muscle tonus of upper airway like phonotherapy or physical therapy among others. Outcomes: decrease or completely stop of snoring, sleep quality, quality of life, and adverse events. Results: Three eligible trials were potentially analyzed, but none of them could provide good scientific evidence favoring the intervention. The objective analyses of one study showed improvement of snoring, although the objective sub-analyses and subjective analyses showed controversial results. The adverse events were not reported. Conclusion: There is no enough evidence to support the recommendation of methods to increase muscle tonus of upper airways in treatment of snoring. Well designed randomized clinical trials are needed to asses the efficacy of such methods, and a standard and worldwide accepted method for snoring assessment would be useful for future researches.Key WOrdS: snoring, sleep disorders, treatment, review. Métodos para aumentar o tônus muscular da via aérea superior no tratamento do ronco: revisão sistemáticaResumo -Contexto: O ronco é o ruído causado pela vibração durante a inspiração, cujas estruturas vibratórias, dependem atualmente de vários fatores. Objetivo: O tratamento do ronco com métodos para aumentar o tônus muscular da via aérea superior tem sido controverso e pouco relatado, portanto uma revisão de evidências é necessária para avaliar a efetividade destes métodos. Método: revisão sistemática de ensaios clínicos randomizados ou quasi-randomizados, duplo-cegos para o tratamento do ronco, com métodos visando o aumento do tônus da via aérea superior, tais como fonoterapia e fisioterapia. desfechos: diminuição ou cura do ronco, qualidade do sono, qualidade de vida e efeitos adversos. Resultados: Três estudos elegíveis foram potencialmente analisados, porém nenhum deles demonstrou evidência científica de qualidade favorecendo a intervenção. As análises subjetivas em um estudo mostrou melhora do ronco, entretanto as sub-análises objetivas demonstraram resultados controversos. Os efeitos adversos não foram relatados. Conclusão: Não existe evidência científica suficiente para sustentar a recomendação de métodos para aumentar o tônus muscular da via aérea superior no tratamento do ronco. ensaios clínicos randomizados bem elaborados são necessários para avaliarmos a eficácia de tais métodos e uma padronização de métodos para intervir no ronco mundialmente aceitos se tornariam úteis em pesquisas futuras.
