Acute airway obstruction is much more common in infants and children than in adults because of their unique anatomic and physiologic features. Even in young patients with partial airway occlusion, symptoms can be severe and potentially life-threatening. Factors that predispose children to airway compromise include the orientation of their larynx, the narrow caliber of their trachea, and their w...

BACKGROUND Lower airway obstruction has evolved to denote pathologies associated with diseases of the lung, whereas, conditions proximal to the lung embody upper airway obstruction. This approach has disconnected diseases of the larynx and trachea from the lung, and removed the 'middle airway' from the interest and involvement of respiratory physicians and scientists. However, recent studies ha...

Laryngoceles are abnormal dilatations of the laryngeal saccule, which rises between the ventricular folds, the base of the epiglottis and the inner surface of the thyroid cartilage. Clinical symptoms are rare, and the find of asymptomatic laryngoceles in pathology studies are frequent. Sometimes it is presented as cervical swelling causing airway obstruction in need of emergency intervention. I...
