Evaluation of Airway Obstruction Using Virtual Endoscopy

Awake versus drug-induced sleep endoscopy: evaluation of airway obstruction in obstructive sleep apnea/hypopnoea syndrome.

OBJECTIVES/HYPOTHESIS To compare the degree and patterns of upper airway obstruction, as detected by endoscopy with Müller's maneuver versus drug-induced sleep endoscopy (DISE). METHODS Sixty-six patients (60 males and 6 females), with a mean age of 49.59 ± 13.04 years, underwent videonasal-pharyngo-laryngoscopy to asses anatomy and dynamic behavior of upper airways during the Müller's maneuv...

The role of CT virtual endoscopy for evaluation of the airway

Purpose Evaluation of airway stenosis secondary to head and neck lesions has been performed routinely with CT scan and endoscopy (1). Endoscopy of a stenotic airway can be difficult, and can be associated with compromise of the airway (2). CT virtual endoscopy (CTVE) provides a noninvasive means of evaluating the airways while simultaneously studying the head and neck soft tissues including vas...

Endoscopic Airway Evaluation in Congenital Tracheoesophageal Fistula - Pediatric airway endoscopy

Introduction. The communication between the trachea and esophagus is called tracheoesophageal fistula (TEF). It can occurs as a congenital malformation (0.025-0.05%) (in particular related to the esophageal atresia) or can occurs as an acquired pathology. Endoscopic evaluation is the gold standard for the diagnosis of TEF and must be performed, in presence of symptoms such as choking, coughing,...
