The airway in the pediatric age group is a complex structure that extends from external nares to junction of larynx and trachea. patients has significant anatomical physiological differences compared adult group. difficult children an important contributor both morbidity mortality patient. symptoms signs with respiratory distress depend on site severity obstruction. It essential evaluate locali...

The exact anatomical site of anesthesia-induced airway obstruction is controversial [3,6-11]. The traditional knowledge postulates that the posterior movement of the tongue by a reduced genioglossus activity is the major cause of airway obstruction [12-14]. More recent studies suggest that the airway obstruction occurs at different sites, such as at the level of epiglottis or soft palate [69,11...

BACKGROUND We compared postoperative complications and oncologic results after laryngectomy of patients with laryngeal squamous cell carcinoma (SCC), with and without airway obstruction. METHODS We retrospectively reviewed the medical records of 544 patients with laryngeal SCC between 1990 and 2000. Of 175 advanced cases receiving total laryngectomy, 32 initially presented with upper airway o...

Although they are extremely effective in maintaining tracheal and subglottic patency, T-tubes themselves can result in airway obstruction from plugging. Many practitioners educate patients on placing a small (5.0) endotracheal tube (ETT) through the tracheal limb of the T-tube if they develop airway obstruction. Unfortunately, this can be a difficult task to complete during acute airway obstruc...

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...

Upper airway obstruction during adulthood is associated with cardiovascular morbidity; cardiovascular consequences of childhood upper airway obstruction are less well established. This study aimed at investigating the effect of childhood upper airway obstruction on respiratory sinus arrhythmia as a measure of cardiac vagal modulation during night-time sleep. Overnight polysomnography was conduc...
