Abstract
Virtual endoscopy (VE) is a computer simulation from the imaging anatomical studies. It is noninvasive, and hence avoids all the complications of invasive conventional endoscopy. VE does not require a pre-procedural patient preparation and had a shorter procedural time. It is a very useful technique in the diagnosis and management of trachea-bronchial injuries and stenosis; placement of tracheostomy cannula in patients with abnormal anatomy; diagnosis of tracheoesophageal and laryngeal traumatic injuries, bronchopleural fistulas, and foreign body in tracheobronchial tree; and diagnosis of inhalational injury and epiglottis.
