[Anatomy of the larynx with 64-CT scan]

ABSTRACT

Knowledge of axial anatomy of the different laryngeal structures, identification of the plan of the cords, and relations between the true and false vocal cords is essential for laryngeal surgery where anatomical and radiological correlation is necessary for optimal orientation and guidance. This review constitutes an atlas of axial anatomy of the larynx obtained from a multidetector CT scan, describing the skeletal cartilage, the different folds constituted by iaryngeal ligaments covered by mucosa, and the fatty laryngeal spaces. It shows that CT scan and the different reconstructions specifically virtual endoscopy are a valuable adjunct in laryngeal exploration
