Three-dimensional imaging of ENT diseases with helical computed tomography.

We have employed helical computed tomography (CT) to evaluate ear, nose and throat diseases, and present herein seven typical cases: middle ear surgery, osteoma of the external ear canal, maxillary fracture, tripod fracture, submandibular gland calculus, epiglottic abscess and vocal fold palsy. Helical (CT) facilitates the assessment of these diseases and its high diagnostic value is described.
