OBJECTIVES This study investigated the outcomes of uvula-preserving palatopharyngoplasty (UPPPP) in patients with obstructive sleep apnea syndrome (OSAS). METHODS Twenty men with obstructive sleep apnea syndrome received the UPPPP operation at our institution. We measured symptom changes after UPPPP using a visual analog scale (VAS), and all patients were examined with polysomnography pre- an...

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...

Detection of desaturations on the pulse oximetry signal is of great importance for the diagnosis of sleep apneas. Using the counting of desaturations, an index can be built to help in the diagnosis of severe cases of obstructive sleep apnea-hypopnea syndrome. It is important to have automatic detection methods that allows the screening for this syndrome, reducing the need of the expensive polys...

Obstructive Sleep Apnea and Obesity Hypoventilation Syndrome are two similar diseases. Obstructive Sleep Apnea has been receiving more and more attention while the diagnostic rate of Obesity Hypoventilation Syndrome is not high. Few studies directly evaluated the relationship between them. We systematically analyzed the relevance of the two diseases. MEDLINE®, EMBASE® and the Cochrane Library w...

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 ...

Two obese patients with sleep apnea syndrome were administered chlormadinone acetate (CMA), a synthetic progesterone, known as a potent respiratory stimulant to augment load compensation response as well as CO2 chemosensitivity. Before CMA administration, both cases showed normal chemosensitivity of hypoxic and hypercapnic ventilatory responses (HVR and HCVR) at daytime, although marked oxygen ...

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 ...

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...

Whether nasal congestion promotes obstructive sleep apnea is controversial. Therefore, we performed a randomized placebo-controlled cross-over trial on the effects of topical nasal decongestion in patients with obstructive sleep apnea syndrome (OSA) and nasal congestion. Twelve OSA patients with chronic nasal congestion (mean +/- SD age 49.1 +/- 11.1 years, apnea/hypopnea index 32.6 +/- 24.5/h)...

The prevalence of obstructive sleep apnea-hypopnea syndrome in the general childhood population is 1-2% and the most common cause is adenotonsillar hypertrophy. However, beyond adenotonsillar hypertrophy, there are other highly prevalent causes of this syndrome in children. The causes are often multifactorial and include muscular hypotonia, dentofacial abnormalities, soft tissue hypertrophy of ...
