Computed tomography (CT) in diagnosis of laryngeal carcinoma was evaluated among 23 patients. CT can provide clinically important findings which may be “blind spots” in laryngeal endoscopic examination: (1) tumor invasion to deep soft tissues such as pre-epiglottic and paraglottic spaces, (2) status of laryngeal cartilages, (3) subglottic extension of neoplasm. However, CT does not demonstrate superficial mucosal lesions in stage I and II of glottic carcinoma and glottic motion. CT is one of the most useful modalities in diagnosis of tumor extent.
