High-resolution computed tomography of the normal larynx
Computed tomography (CT) provides a unique method of evaluating abnormalities of the larynx by virture of its cross-sectional images. Several reports have demonstrated its utility in staging laryngeal carcinoma and defining the extent of injury in cases of laryngeal trauma. In order to appreciate subtle abnormalities of the larynx, a thorough understanding of the normal structures in this small anatomic area is crucial. Although previous studies have defined the normal CT anatomy of the larynx, many of the CT-anatomic correlations of the normal larynx used earlier-generation CT scanners with relatively poor resolution or were limited to transaxial images. High-resolution transaxial, coronal, and sagittal CT in vivo images are correlated with line drawings displaying normal laryngeal anatomy. The exquisite anatomic detail apparent in these images provides a sound basis for understanding subtle abnormalities in pathologic cases. (JMT)
