Amongst the pair, the right lung is divided into three lobes namely upper, middle and lower by oblique and horizontal fissures. Being vital organs of respiration, the lungs are divided by fissures into lobes which facilitate movements of lobes in relation to one another. The lungs are essential organs of respiration and are situated in the thoracic cavity on either side of the mediastinum. Keywords: Lung, Hilum, Pulmonary, Lobe, Fissure The knowledge of variations in the lobar and hilar anatomy of the lung presented in this study is clinically important while interpreting the radiological images and performing surgical procedures. Twenty-one point nine one percent of left lungs had 2 bronchi and 78.08% had only one bronchus in the hilum. Eighty point eight two percentage of left lungs had two veins in the hilum and 19.17% had 3 veins in the hilum. Five point four seven percentage of left lungs showed 2 arteries and 94.52% had only one artery in the hilum. Fifteen point zero six percentage of left lungs showed incomplete oblique fissure and 2.73% showed 2 fissures and 3 lobes. Two of the right lungs (3.07%) had an artery passing across the oblique fissure. Ninety-eight point four six percentage of right lungs showed 2 bronchi in the hilum, and 1.53% of them showed 3 bronchi in the hilum. Sixty-three point zero seven percentage of right lungs had two veins in the hilum 32.30% had 3 veins in the hilum and 4.61% had more than 3 veins in the hilum. Three point zero seven percentage of right lungs had 3 arteries, 67.69% had 2 arteries, and 29.23% had only one artery in the hilum. Four point six one percentage of right lungs had 3 fissures and 4 lobes. Horizontal fissure was absent in 3.07% and incomplete in 35.38% of right lungs. We studied the variations of fissures, lobes and hilar structures in 65 right and 73 left isolated lungs from the dissection hall. Awareness of anatomical variations in lungs is essential during segmental or lobar resections of lungs.
