OBJECTIVE To assess the effect of uvulopalatopharyngoplasty (UPPP) on positional dependency in patients with obstructive sleep apnea (OSA). DESIGN Retrospective analysis. SETTING Tertiary care university hospital. PATIENTS Ninety-six patients who underwent UPPP because of OSA from June 1, 2004, through July 31, 2008, were included. Both preoperative and postoperative attended full-night p...

Obstructive sleep apnea (OSA) is associated with cardiovascular, cerebrovascular, and metabolic disease.1-3 Treatment of OSA with continuous positive airway pressure (CPAP) can ameliorate high blood pressure4 and insulin resistance.5 Because OSA is a prevalent disorder affecting 4.5% and 3.2% of Korean men and women, respectively,6 adequate screening for the disease is a major health issue. The...

Background: Many reports are available about the increasing rate of mortality due to overuse of opioids. It has been suggested that sleep apnea can be a cause of mortality because of overuse of opioids. Opium use is common in Iran. This study aimed to assess the effect of opium on polysomnographic findings in opium addicts with sleep apnea syndrome. Materials and Methods: In this prospective ca...

RATIONALE Obstructive sleep apnea syndrome is due to upper airway obstruction and is associated with increased morbidity. Although continuous positive airway pressure efficaciously treats obstructive apneas and hypopneas, treatment is impeded by low adherence rates. OBJECTIVES To assess the efficacy on obstructive sleep apnea of a minimally intrusive method for delivering warm and humidified ...

OBJECTIVE To evaluate the effects of a mandibular advancement device on apneas and sleep in mild, moderate, and severe obstructive sleep apnea. DESIGN Prospective study. SUBJECTS Forty-four of 47 patients included. INTERVENTION Individually adjusted mandibular advancement devices. MEASUREMENTS Polysomnographic sleep recordings for 1 night without the device and 1 night with it, with a m...

INTRODUCTION The sympathetic activation is considered to be the main mechanism involved in the development of cardiovascular diseases in obstructive sleep apnea (OSA). The heart rate variability (HRV) analysis represents a non-invasive tool allowing the study of the autonomic nervous system. The impairment of HRV parameters in OSA has been documented. However, only a few studies tackled the dyn...

OBJECTIVE To determine polysomnographic (PSG) variables that may potentially predict adverse respiratory events after pediatric adenotonsillectomy. DESIGN Retrospective, case-control study. SETTING Free-standing academic tertiary-care pediatric hospital. PATIENTS The study included 1131 patients undergoing adenotonsillectomy by 2 attending surgeons. There were no exclusion criteria. MAI...

BACKGROUND Maxillomandibular advancement (MMA) surgery is a surgical treatment option for treating the patients with obstructive sleep apnea (OSA). Surgical treatment of OSA by MMA surgery is a problem when it is encountered with an edentulous patient because of the intermaxillary fixation problem of the jaws. A paucity of information is available concerning MMA surgery for edentulous patients....
