Introduction: Human lung, both right as well as left shows lot of variations in their length, breadth, thickness from person to person. Even the fissures and lobes in both the lungs show a variety of variations as shown by previous workers1-7. Apart from studying the variations of fissures and lobes in this study we have measured the length, breadth and thickness of both right and left Lungs and we have also measured the length and depth of transverse and oblique fissures of both the lungs right and left. Such measurements have not been done previously. Aims and objectives: To study the normal length, breadth and thickness of both, right and left lungs and also to study the variations in the length, breadth and thickness, of both right and left lungs and finally to study the normal fissures, lobes and their variations, of both right and left lungs. Materials and Methods: 13 Right and 14 left lungs obtained from embalmed cadavers, used for dissection in the Anatomy department, as a part of 1st year MBBS curriculum, of Geetanjali medical college and Hospital, Udaipur, formed the material for the current study. Results: The left lung shows maximum variations of fissures in that they show an extra transverse fissure which is normally absent in the left lung. Out of 14 left lungs 5 of them that is 35.71%. Out of 14 left lungs 2 of them that is, 14.28% showed absence of oblique fissures. In case of right lungs out 13 only one of them that is, 7.69% showed absence of transverse fissures. Average measurements (length, breadth, thickness) of Right and left lungs have been measured.
