ABSTRACT
PURPOSE:
Computed tomographic virtual laryngoscopy is a non-invasive radiological technique that allows visualisation of intra-luminal surfaces by three-dimensional reconstruction of air/soft tissue interfaces. It is particularly useful when the patient cannot tolerate clinical examination, when infection, neoplasm or congenital defects compromise the lumen and for assessment of the sub-glottic region. We have performed virtual laryngoscopy on patients referred because of upper airway symptoms, and compared the findings with those at conventional laryngoscopy. MATERIALS ANDMETHODS:
Axial scans were obtained using a Toshiba Xpress helical scanner. Virtual laryngoscopy was then performed on a workstation using Toshiba "Fly-thru" software and was completed within 5 min.RESULTS:
Pathology included vocal cord nodules, laryngeal cysts, Reinke's oedema, laryngeal neoplasms and leukoplakia.CONCLUSIONS:
Virtual laryngoscopy displays anatomical detail comparable to conventional endoscopy. Impassable obstructions are no hindrance and all viewing directions are possible. It is especially useful for providing views of the larynx from below.
