The purpose of this study was to analyze acupuncture treatment methods and acupoints used to treat obstructive sleep apnea (OSA) or obstructive sleep apnea-hypoapnea syndrome (OSAHS). The data were retrieved from January 2010 to May 2022 from the China National Knowledge Infrastructure database. The search terms included "adult," "obstructive sleep apnea," "obstructive sleep apnea hypoapnea syndrome," "acupuncture," and "electro-acupuncture." Clinical trials for acupuncture treatment of OSA or OSAHS were included in this review (4 non-randomized controlled studies, 1 was a case report, and 10 randomized controlled studies). For OSA and OSAHS treatment, the acupoints that were most frequently used included REN23, LU7, ST40, EX9, LI11, and DU20. Compared with the control or Western treatment group, the treatment outcome measures of participants in the acupuncture treatment group significantly improved. In some studies, participants in the acupuncture group did not have side effects and the treatment was cost-effective. The data analyzed in this review suggest that acupuncture is an effective treatment for OSA or OSAHS.

In this study, OSA (the obstructive sleep apnea) periods were detected in patients with OSA during sleep because of the treatment was different according to the frequency and symptoms of obstructive sleep apnea. ANS (autonomic nervous activity) was changed by obstructive sleep apnea periods so we intended to detect the periods to care the obstructive sleep apnea patients. RR intervals, SDNN (standard deviation of normal to normal) and RMSSD (root mean square standard deviation) were calculated in time domain analysis and LF (low frequency), HF (high frequency), NHF (normalized high frequency), NLF (normalized low frequency) were calculated in frequency domain analysis of HRV (heart rate variability) with obstructive sleep apnea patients. In this paper, SDNN (standard deviation of normal to normal) of time domain analysis were decreased in the obstructive sleep apnea periods. And NLF and LF/HF ratio were increased and NHF (normalized high frequency) was decreased in the frequency domain analysis. The parameters can be used to treat obstructive sleep apnea patients by detecting the obstructive sleep apnea periods such as CPAP (continuous positive airway pressure).

Obstructive sleep apnea syndrome (OSAS) is characterized by obstructive events of the upper airway (UAW) during sleep, which can be associated with clinical signs and symptoms such as snoring, excessive daytime sleepiness, impaired memory, and fatigue. It is associated with many problems like psychosocial problems, physiologic alterations in the cardiovascular and respiratory systems as a result of hypoxia and repeated awakenings during sleep. Conservative treatments such as weight loss, sleep positioning, improvement of sleep hygiene, CPAP and MAD can be performed for the obstructive sleep apnea. However, their effect for the OSA is limited and differs by patient's individual properties. Accordingly, surgical reconstructions of the upper airway must be carried out for the treatment of OSA.

Objectives: Obstructive sleep apnea (OSA) is common in people with epilepsy (PWE), and confers medical and seizure-related consequences when untreated. Positive airway pressure, the gold-standard for OSA management, is limited by tolerability. As serotonin is involved respiratory control and amelioration of seizure-induced respiratory events, this study aims to determine whether serotonin reuptake inhibitors (SRIs) may represent a potential therapeutic option. Methods: A retrospective study of 100 PWE and OSA ${\geq}18$ years of age was conducted. The primary outcome measure was OSA severity as function of SRI use, with rapid eye movement (REM)-related OSA as a secondary outcome. Results: Older age and depression were more common in those taking an SRI. There was no association between SRIs and OSA severity. However, the SRI group was less likely to have REM-related OSA. Conclusions: In PWE and OSA, SRI use is associated with reduced risk of REM-related OSA, and may represent a potential management strategy.

Sleep-disordered breathing (SDB) is defined as a disturbed breathing during sleep caused by repetitive upper airway collapse. Complete collapse causes a cessation of breathing, known as obstructive sleep apnea (OSA) and snoring can arise from partial collapse. Undiagnosed and untreated OSA means recurrent intermittent hypoxemia and leads to a variety of cardiovascular disorders, disturbed neurocognition, and excessive daytime sleepiness. Various behavioral modalities have been suggested for treating snoring and sleep apnea including changing the sleep position, avoiding alcohol, and weight loss. Until now continuous positive airway pressure (CPAP) therapy is one of effective treatment for patients with OSA, but its discomfort causes less tolerance and compliance. Therefore, clinical effectiveness and convenience for oral appliance have emerged and the role of dentists has become more important in the management of OSA.

Objectives: Obstructive sleep apnea (OSA) is prevalent disorder, particularly among the middle-aged. In this study, we report a new approach to improve OSA using oriental medicine and acupuncture. Methods: Three men diagnosed with OSA were enrolled in this study. They took oriental medicine 3 times a day and were given acupuncture twice a week for about 4 months. Results: We analyzed apnea-hypopnea index (AHI), oxygen desaturation index (ODI), average saturation (AS) and lowest saturation (LS) before and after treatment. AHI highly decreased in all patients and ODI also decreased in two of the three patients. Conclusions: These results indicate that oriental medicine and acupuncture therapy was effective in the improvement of OSA. Further study in a larger group with severity grades is recommended.

Obstructive sleep apnea (OSA), most common respiratory disorder of sleep, is characterized by intermittent partial or complete occlusions of the upper airway due to loss of upper airway dilating muscle activity during sleep superimposed on a narrow upper airway. Termination of these events usually requires arousal from sleep and results in sleep fragmentation and hypoxemia, which leads to poor quality of sleep, excessive daytime sleepiness, reduced quality of life and numerous other serious health consequences. Untreated OSA may cause, or be associated with, several adverse outcomes, including daytime sleepiness, increased risk for motor vehicle accidents, cardiovascular disease, and depression. Various treatments are available, including non-surgical treatment such as medication or modification of life style, continuous positive airway pressure (CPAP) and oral appliance (OA). Skeletal surgery for obstructive sleep apnea (OSA) aims to provide more space for the soft tissue in the oropharynx to prevent airway collapse during sleep. Conventional surgical techniques include uvopalatopharyngoplasty(UPPP), genioglossus advancement (GA), and maxillomandibular advancement (MMA). Surgical techniques, efficacy and complications of skeletal surgery are introduced in this review.

Obstructive sleep apnea (OSA) is a common disorder characterized by recurrent cessation of breathing due to complete or partial upper airway occlusion during sleep. The incompetent tone of palatal, pharngeal, and glossal muscles which fail to maintain airway patency during sleep causes narrowing of the airway dimension and increased resistance of breathing. The identification of the sites of upper airway obstruction in patients with OSA is important in understanding the pathogenesis and deciding the treatment modality of snoring and/or OSA. Various upper airway imaging modalities have been used to assess upper airway size and precise localization of the sites of upper airway obstruction during sleep. Dynamic imaging modalities enabled assessment of dimensional changes in the upper airway during respiration and sleep. This article focused on reviews of various upper airway imaging modalities, especially dynamic upper airway imaging studies providing important information on the pathogenesis of OSA.

Maxillomandibular advancement (MMA) is effective for the treatment of obstructive sleep apnea (OSA). In previous studies, the airway was increased in the anteroposterior and transverse dimensions after MMA. However, the effect of the opposite of mandibular movement (mandibular setback) on the airway is still controversial. Mandibular setback surgery has been suggested to be one of the risk factors in the development of sleep apnea. Previous studies have found that mandibular setback surgery could reduce the total airway volume and posterior airway space significantly in both the one-jaw and two-jaw surgery groups. However, a direct cause-and-effect relationship between the mandibular setback and development of sleep apnea has not been clearly established. Moreover, there are only a few reported cases of postoperative OSA development after mandibular setback surgery. These findings may be attributed to a fundamental difference in demographic variables such as age, sex, and body mass index (BMI) between patients with mandibular prognathism and patients with OSA. Another possibility is that the site of obstruction or pattern of obstruction may be different between the awake and sleep status in patients with OSA and mandibular prognathism. In a case-controlled study, information including the BMI and other presurgical conditions potentially related to OSA should be considered when evaluating the airway. In conclusion, the preoperative evaluation and management of co-morbid conditions would be essential for the prevention of OSA after mandibular setback surgery despite its low incidence.

Obstructive Sleep Apnea(OSA) is a form of sleep disordered breathing(SDB) characterized by the occurrence of episodes of complete or partial upper airway obstruction during sleep that is often quantified as the apnea-hyponea index(AHI). It is increasingly being recognized that OSA is a public health hazard and there is increasing evidence that it is associated with an increase in morbidity. Early recognition and diagnosis of this condition may lead to earlier treatments (eg, CPAP, Oral appliances) with reduction of the risk of metabolic disease, cardiovascular diseases, such as hypertension, ischemic heart disease, arrhythmias and pulmonary hypertension.
