Introduction: Acute epiglottitis or supraglottitis is a rapidly progressing upper respiratory tract infection that can often threaten the airway patency. Epiglottic abscess that expands to the paraglottic (PGS) or preepiglottic (PES) space and acute airway obstruction constitute rare complications, exclusively presented in adults.   Case Report: We report two cases. In t...

BACKGROUND Central airway obstruction is a common complication of lung cancer. The microdebrider is a new device available for treatment of central airway obstruction. CASE DESCRIPTION We report a case a 59-yr-old male with T3N2M1 non-small cell lung cancer with malignant distal left mainstem obstruction treated successfully with a novel elongated rotating tip microdebrider via rigid bronchos...

Obstructive sleep apnea is the result of repeated episodes of upper airway obstruction during sleep. Recent evidence indicates that alterations in upper airway anatomy and disturbances in neuromuscular control both play a role in the pathogenesis of obstructive sleep apnea. We hypothesized that subjects without sleep apnea are more capable of mounting vigorous neuromuscular responses to upper a...

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...

High dose rate (HDR) endobronchial brachytherapy is a palliative treatment for symptomatic airway obstruction by malignant tumours. We report a novel use of HDR brachytherapy for treating non-malignant bronchial obstruction. The patient had a metal stent placed in a reconstructed airway after a bronchial tear to ensure patency. Granulation tissue formation in and around the stent caused symptom...

Lung cancer complications are the leading cause of death in lung patients. This study aimed to describe prevalence stent placement, indications for success and complication rates, prognosis airway placement patients with cancer. Malignant central obstruction (MCAO) is one significant complications. Insertion can restore patency more than 90% MCAO. Airway indicated extrinsic lesions, ≥ 50%, have...

Congenital nasal pyriform aperture stenosis (CNPAS) is a recently defined clinical entity that causes airway obstruction in the neonate as a result of narrowing of the nasal pyriform aperture. The pyriform aperture is the narrowest, most anterior portion of the nasal airway, and a slight decrease in its cross sectional area will significantly increase the nasal airway resistance. This entity sh...
