OBJECTIVE To explore the feasibility and efficacy of Z-palatoplasty for the management of severe obstructive sleep apnea-hypopnea syndrome in patients with tonsils. STUDY DESIGN Case series and chart review. SETTING University hospital. METHODS Z-palatoplasty and coblation channeling of the tongue were performed in 36 patients with body mass index <40 kg/m(2) and size 1 or 2 tonsils. All ...
Objective: Obstructive sleep apnea-hypopnea syndrome (OSA) is a disease of obstructive apnea or hypopnea caused by repeated partial complete collapse the upper airway during sleep. The inspiratory part flow-volume curve (F-V curve) can be used as an auxiliary means to evaluate obstruction in adults. This study ability F-V predict OSA and explore indicators related Methods: There were 332 patien...
INTRODUCTION Autonomic dysfunction can alter heart rate variability and increase the incidence of arrhythmia. We analyzed the impact of continuous positive airway pressure (CPAP) on this pathophysiological phenomenon in patients with severe sleep apnea-hypopnea syndrome. METHODS Consecutive patients with recently diagnosed severe sleep apnea-hypopnea syndrome were prospectively considered for...
The physiopathology of obstructive sleep apnea syndrome is multifactorial. Gender and obesity status, as well as genetic, anatomic, and hormonal factors, together with ventilatory drive, interact in a diverse manner in the physiopathology and clinical expression of the disease. Obesity is the main risk factor, since increases in body mass index, visceral fat, and neck circumference are strong p...
Cardiovascular and cerebrovascular diseases are the most common diseases in industrialized societies. The main objectives of this article were to summarize the physiological effects of sleep apnea on the circulatory system and to review how treatment of this condition influences cardiovascular disease. Acute sleep apnea has a number of hemodynamic consequences, such as pulmonary and systemic hy...
INTRODUCTION Obstructive sleep apnea syndrome has a high prevalence among adults. Cephalometric variables can be a valuable method for evaluating patients with this syndrome. OBJECTIVE To correlate cephalometric data with the apnea-hypopnea sleep index. METHODS We performed a retrospective and cross-sectional study that analyzed the cephalometric data of patients followed in the Sleep Disor...
OBJECTIVE To validate the BREAS SC20 (Breas Medical AB, Mölnlyke, Sweden) polygraphic screening device, comparing it with conventional polysomnography (PSG), in the diagnosis of sleep apnea-hypopnea syndrome. A validity study of the diagnostic test was carried out at the sleep clinic of a tertiary hospital. PATIENTS AND METHODS Seventy patients clinically suspected of sleep apnea-hypopnea syn...
