초록

The fissures of lungs are embryologically separating the bronchopulmonary segments, which later on persist in interlobar planes of fully developed lung. Fifty lungs (23 right side and 27 left side), obtained during routine dissection and preserved in formalin constituted the material for present study. In them, variations in fissures and lobes of lung were observed and compared with the previous studies. Seven right sided and 14 left sided lungs showed incomplete oblique fissure. Incomplete horizontal fissure of right lung was observed in eight lungs while it was completely missing in three specimens. A right lung with "lobe of the azygos vein" separated by a supernumerary fissure in medial surface was found. One of the right lung had both superior accessory fissure and inferior accessory fissure and four other right lungs and one left lung presented only with inferior accessory fissure. A vertical notch was found in middle lobe of one right lung. Eight left lungs exhibited with left minor fissure among them two lungs had lingula appearing as a separate lobe. Knowledge of variations in fissures and lobes is of interest to all medical professionals to exactly interpret radiographs, computed tomography scans, to diagnose, plan and modify a surgical procedure depending on the merit of the case and also in certain classical clinical cases pertaining to lung pathologies.
