Introduction: This study aimed to investigate sleep architecture in patients with primary snoring and obstructive sleep apnea. Methods: In this study, we analyzed polysomnographic data of 391 clients who referred to Sleep Disorders Research Center (SDRS). These people were classified into three groups based on their Apnea-Hypopnea Index (AHI) and snoring; control, Primary Snoring (PS), and Obs...

Chiari Type I malformation (CM-I) is a rare disorder with displaced cerebellar tonsils through foramen magnum. Here we present a 30-year-old man with severe central and obstructive sleep apneas as presenting manifestations of CM-I. The patient underwent neurosurgery and the follow-up polysomnography revealed the resolution of central apnea while obstructive apnea remained unchanged. Central sle...

BACKGROUND Previous studies have documented a high prevalence of atrial fibrillation (AF) in individuals with obstructive sleep apnea (OSA). Central sleep apnea (CSA) has been associated with AF in patients with heart failure. However, data from prospective cohorts are sparse and few studies have distinguished the associations of obstructive sleep apnea from CSA with AF in population studies. ...

BACKGROUND Distraction advancement has been advocated for treatment of obstructive sleep apnea associated with congenital midface hypoplasia. The purpose of this study was to relate changes in maxillary position to changes in obstructive sleep apnea measures on polysomnography in a consecutive series of patients. METHODS Among 26 syndromic pediatric patients undergoing Le Fort III distraction...

T he syndrome of sleep apnea has been described throughout the ages, dating at least to descriptions of Dionysius the Tyrant in the fourth century BC. It is only recently that scientific investigation has led to an understanding of this previously ill-defined syndrome. Sleep apnea is the currently accepted term for a group of heterogeneous sleep-associated respiratory disorders. The most common...

Morbid obesity is associated with a more rapid decrease in oxygen saturation during apnea following induction of anesthesia, compared to patients who have normal weight1. This is particularly hazardous as morbid obesity, complicated by obstructive sleep apnea, may be associated with an increased risk of difficult tracheal intubation and difficult face mask ventilation2. These morbidly obese pat...

Obstructive sleep apnea is a sleep disorder of airflow at the nose and mouth during sleep. Patients with undiagnosed sleep apnea represent a major public health problem. Dental professionals have a unique doctor patient relationship that can help them in recognizing the sleep disorder and managing the patients along with a physician or a sleep specialist. Oral appliance therapy is an important ...

INTRODUCTION Obstructive sleep apnea occurs by recurrent collapse of the upper airway during sleep, resulting in total (apnea) or partial (hypopnea) reduction of the airflow and has intimate relation with changes in the upper airway. Cone Beam CT allows the analysis of the upper airway and its volume by three-dimensional reconstruction. OBJECTIVE To evaluate a possible correlation between the...

OBJECTIVES/HYPOTHESIS To determine if supraglottoplasty (SGP) is effective in reversing abnormal respiratory parameters in children with laryngomalacia and obstructive sleep apnea (OSA). STUDY DESIGN Retrospective case series at a tertiary referral children's hospital. METHODS Ten patients with laryngomalacia and OSA as documented by polysomnography underwent SGP between 2005 and 2007. Data...
