Assessment of Malignant Laryngeal Neoplasms Office-Based Endoscopy and Direct laryngoscopy Compared with Computed Tomography of The Neck

Abstract

Direct laryngosocpy and office based endoscopy showed very close results as regards assessment of the extension and detection of early stages of malignant neoplasms, also showed high sensitivity and specificity in detecting true +ve and true –ve cases, thus DL and OB endoscopy are the cornerstone of diagnosing laryngeal neoplasms. Computed topography showed less sensitivity and specificity in the assessment of malignant laryngeal neoplasm, particularly in detection of early glottic lesions, with high false +ve results (vocal fold immobility or edema appearing as mass in the larynx). Thus CT is not reliable as the 1ry diagnostic tool in malignant laryngeal neoplasms. CT showed better sensitivity and specificity in detecting supralaryngeal masses with results close to DL and OB endoscopy.
