Introduction: The fissures facilitate the movement of the lobes in relation to one another, which accommodates greater distention and movement of the lobes during respiration. The fissures may be complete, incomplete or absent altogether. Aim of the Study: To study the morphology of fissures and lobes, to note the variations, to compare them with previous studies and to find their clinical significances. Materials and Methods: Forty pairs of lungs obtained from formalin-fixed adult cadavers removed during routine dissection at J. N. Medical College, Belagavi were studied. These lungs were meticulously observed for the patterns of lobes and fissures, variations were noted and photographed. Results: In the present study oblique fissure was absent in 10% of right lungs and 7.5% of left lungs. Incomplete horizontal fissure was seen in 52.5% of right sided lungs. Conclusion: This study also shows that parenchymal fusion of various extents is a very common entity of oblique fissure of lung. This implies that a variety of genetic and environmental factors might affect development of these fissures.
