Abstract: This study included consecutive 318 pairs of posteroanterior (PA) and left lateral (LL) chest radiographs taken under routinely used conditions with the patients in erect position. Major, minor and accessory fissures visualized on these radiographs were described according to their visibility, position, length and shape. On PA chest radiographs, superolateral major fissures in 54 (17%), superomedial major fissures in 20 (6%), minor fissures in 234 (74%), inferior accessory fissures in 19 (6%), superior accessory fissures in 12 (4%), left minor fissures in 16 (5%) and azygos fissure in 2 (0.6%) patients were seen. On LL chest radiographs, 266 (84%) right major fissures, 242 (76%) left major fissures, 210 (66%) minor fissures and 6 (2%) superior accessory fissures were seen. We have described the frequencies of various orientations, shapes and lengths of these fissures. This study not only supports the common knowledge of the appearances of pulmonary fissures but also explains numerically the various frequencies of these common patterns and variations seen in practice.
