Cadaveric study of morphological variations of fissures and lobes of lungs and their clinical significance

Journal Title: Medpulse International Journal of Anatomy - Year 2017, Vol 4, Issue 1

Abstract

Background: Anatomical variations of lungs which include fissures and lobes of lungs are very necessary for the clinicians for recognizing their variable imaging appearances as well as related abnormalities. Aims and Objectives: So present study was undertaken to note such variations and compare these results with the other studies as well as to identify their clinical significance. Methods: For the study 32 pairs of formalin fixed lungs were taken. These specimens were cleaned, fine dissected and thoroughly observed for any variations of the fissures and lobes of the lungs. Variations were noted and photographed. Results: Among the left lungs, 01 showed presence of incomplete oblique fissure while in another lung there was total absence of oblique fissure, although in one lung there was presence of oblique fissure in the middle part of lung on the sternocostal surface. Accessory fissure was seen in 07 lungs. In right lungs 02 had incomplete oblique fissure, while horizontal fissure was incomplete in 12 lungs. 05 lungs were without the horizontal fissure. Accessory fissure was present in 05 lungs. Conclusion: The present results showed variations on the left side in 35.71% of total lungs in the form of incomplete/absent oblique fissure and presence of accessory fissure. On the right side 75% of the total lungs showed variations in the form of incomplete/absence of fissures and presence of incomplete fissures. These results were compared with previous studies n found to be correlated. Knowledge of these variations is important for both the diagnosis and treatment of various diseases of lungs.
