background nasal septal deviation (nsd) can cause upper airway obstruction, which results in hypoxia and therefore, pulmonary vasoconstriction, ventricular hypertrophy and right-sided heart failure. objectives the aim of this study is to determine the mean pulmonary arterial pressure (mpap) of the patients with nsd and the effect of septoplasty on pulmonary arterial pressure. patients and metho...

Wheezing and dyspnoea are typical symptoms of asthma but can also be found in diseases of the extrathoracic airways. Functional upper airway obstruction may imitate, as well as complicate asthma. Functional upper airway obstruction was first described as a conversion disorder in young females with inspiratory stridor. Subsequently, it was found that functional upper airway obstruction was more ...

BACKGROUND Obesity is thought to be a significant risk factor for upper airway obstruction during sleep in children. However, the moderating influences of age and ethnicity have not been well explored and the relative contribution of obesity per se to upper airway obstruction has yet to be quantified. Given the markedly increasing prevalence of childhood obesity, an objective understanding of t...

treacher collin’s syndrome (tcs) is a rare inherited condition characterized by bilateral and symmetric abnormalities of structures within the first and second bronchial arches. patients with tcs present a serious problem to anesthetists maintaining their airway as upper airway obstruction and difficult tracheal intubation due to severe facial deformity. because of retrognathia, airway manageme...

To evaluate the effects of current supportive care measures for the adult respiratory distress syndrome (ARDS) upon the upper airway, we studied 30 survivors of ARDS. All patients were interviewed and examined and performed inspiratory and expiratory maximal flow-volume curves more than six months after the onset of ARDS. Three women had developed symptomatic upper airway obstruction due to lar...

Laryngomalacia is the most common cause of neonatal stridor, accounting for up to 60% of cases [1]. Less common causes of neonatal stridor include subglottic or tracheal stenosis, or congenital masses of the upper airway. Neonates with an identified congenital etiology of symptomatic upper airway obstruction often have synchronous airway lesions leading to multilevel airway obstruction. These i...

In this review, the characters of children who are admi t ted to PICU wi th severe upper a i rway obstruction will be discussed further. Difficulties of in tubat ion, ind icat ions and compl icat ions o f t racheo tomy w i l l be d i scussed a f te rwards . Angioedema, bacterial tracheitis, acute epiglottitis and croup will be discussed with details separately. Laryngomalacia will also be discu...
