Findings from rigid telescopic videolaryngoscopy RTV and CTVL images were evaluated and compared with reference to operative records.Results: Lesions localized in the base of the tongue, pyriform sinüs, aryepiglottic folds, and arytenoids were well visualized by both RTV and CTVL. The two techniques were not found effective in identifying lesions of the ventricular bands, ventricular cavities, and the anterior commissure. Virtual laryngoscopy was superior to RTV in the visualization of the sub- glottic area and vocal cords.Conclusion: Virtual laryngoscopy is a noninvasive and reliable technique that provides visualization of endolaryngeal surfaces and tumor extension. İt may be beneficial in staging larynx carcinoma and plan- ning the most appropriate surgical procedure.}, number={3}, publisher={Istanbul University}
