Abstract
Virtual laryngoscopy is a useful adjunctive radiological tool in the assessment of laryngeal lesions. A total of 10 patients requiring direct laryngoscopy for the investigation of laryngeal lesions underwent preoperative virtual laryngoscopy using three-dimensional reconstruction of two-dimensional computerized tomography (CT) images. All lesions were correctly diagnosed on virtual laryngoscopy before direct laryngoscopy. Its main advantages are that it does not require general anaesthesia, it allows three-dimensional visualization of the airway beyond areas of narrowing and it gives a highly accurate representation of vocal cord lesions, both in terms of definition and spatial representation. Its disadvantages are that it does not provide histology, it requires an air-mucosa interface to produce an image and it cannot identify functional lesions of the vocal cords.
