Laryngo-tracheal obstruction: results of surgical technique and role of virtual endoscopy in patient evaluation

ABSTRACT

Introduction: upper airway obstruction is a continuous challenge in diagnosis especially if surgical intervention is required. [1-2-3-4-5] Virtual laryngoscopy [VL] is a technique for creating computer simulations of anatomy from radiological image data and viewing those simulations in a way that is analogous to conventional endoscope.[6]
