Imaging in congenital aural atresia

High-resolution computed tomography remains the gold standard for imaging patients with congenital aural atresia. It is the single most important test for patients with atresia and determines their candidacy for surgery. Magnetic resonance imaging is of limited value because it does not image bone. Three-dimensional computed tomography of the temporal bone is rapidly emerging as a procedure with much potential, both as a preoperative diagnostic test and as a biomedical teaching tool.
