S noring and Obstructive Sleep Apnea Snoring is a common problem encountered in Thailand. The actual prevalence of snoring in Thailand is unknown, but it is estimated to be about 20% in middleaged male and 5% in middle-aged female in foreign countries. The percentage of elderly people who snore is higher. Most people understand that snoring is normal in daily life, but it actually indicates upp...

Acute epiglottitis is an acute inflammation in the supraglottic region of the oropharynx which is a potentially life-threatening condition leading to rapid upper airway obstruction. An infrequent sequel of acute epiglottitis is the epiglottic abscess. Less than 50 cases have been reported in the international literature and even less are the cases that acute surgical intervention was necessary ...

statement of problem: nasopharyngeal obstruction by adenoid enlargement is one of the main causes of mouth breathing. diagnostic indices of nasopharyngeal obstruction by lateral cephalometric radiography are controversial. purpose: the purpose of this study was to diagnose the nasopharyngeal obstruction by means of lateral cephalometric radiography. materials and methods: in this research two g...

Upper airway obstruction in the pediatric population has a myriad of etiologies, some of which are easily overseen. We emphasize the importance of thorough airway examination and careful attention to unusual signs, which, in this case, uncovered a fatal tumor.

UNLABELLED The use of nasopharyngoscopy during the application of intrathoracic pressure (Müller maneuver) is frequently employed to establish the site of upper airway obstruction. The Müller maneuver, however, is used when the patient is awake and therefore may not correlate with obstruction occurring during sleep. AIM To compare the degree of pharyngeal obstruction in the retropalatal and r...

We investigated the influence of obesity on upper airway obstruction, especially the relationship between obesity and the type of obstruction. The site of obstruction was identified by means of endoscopic examination and dynamic MRI during sleep. Many obese patients have the circumferential type of obstruction.

BACKGROUND Obstructive sleep apnea (OSA) is a major clinical disorder that is characterized by multiple episodes of upper airway obstruction due to the failure of the upper airway dilator muscles to maintain upper airway patency. This results in chronic intermittent asphyxia (CIA) due to repetitive apneas, but very little is known about the effects of CIA on upper airway muscle function. OBJE...

To examine the mechanics of infantile obstructive sleep apnea (OSA), airway pressures were measured using a triple-lumen catheter in 19 infants (age 1-36 wk), with concurrent overnight polysomnography. Catheter placement was guided by correlations between measurements of magnetic resonance images and body weight of 70 infants. The level of spontaneous obstruction was palatal in 52% and retroglo...

RATIONALE Obesity imposes mechanical loads on the upper airway, resulting in flow limitation and obstructive sleep apnea (OSA). In previous animal models, leptin has been considered to serve as a stimulant of ventilation and may prevent respiratory depression during sleep. We hypothesized that variations in leptin concentration among similarly obese individuals will predict differences in compe...
