Objectives: We evaluated the utility of computed tomography Virtual laryngoscopy CTVL in identifying endolaryngeal lesions in laryngeal tumors.Patients and Methods: Virtual laryngoscopic images were obtained from axial CT seans of 21 patients with known laryngeal carcinoma. 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.

Amaç: Larengeal tümörlü hastalarda, endolarengeal lezyon tayininde bilgisayarlı tomografi BT sanallarengoskopinin etkinliği araştırıldı.Hastalar ve Yöntemler: Larengeal kanserli 21 hastada kontrastlı aksiyel BT kesitlerinden sanal larengoskopi görüntüleri elde edildi. Hastaların rijit teleskopik videolarengoskopik muayene bulguları ve sanal larengoskopi bulguları ameliyat kayıtlarıyla karşılaştırıldı.Bulgular: Dil kökü, priform sinüs, ariepiglottik bantve aritenoid seviyelerindeki lezyonlar her iki yöntemle de güvenilir bir şekilde gösterilebildi. Ventriküler bant, ventriküler kavite ve anterior komissürseviyelerindeki lezyonlar için her iki yöntem de güvenilir değildi. Subglottik bölge ve vokal kordlardasanal larengoskopinin lezyon tayini daha güvenilirbulundu.Sonuç: Sanal larengoskopi endolarengeal yüzeylerin görüntülenmesinde ve tümör yayılımının saptanmasında invaziv olmayan ve güvenilir bir yöntemdir.Larenks kanserli hastalarda cerrahi öncesi evrelemeve uygun cerrahi tekniğin seçiminde yararlı olabilir
