Study of the Variations in Lobes and Fissures of the Lung- A Cadaveric Study

Abstract

Aim of the study:Aim is to study the variations in the lobes and fissures of lung and its applied importance in clinical or surgical fields. Materials and Methods:In the dissection hall of BRIMS Bidar, Karnataka 49 lungs were taken from the cadavers (formalin fixed) and the details were photographed and recorded.Results:100% of the lungs from female cadavers and 61.90% of the lungs from the male cadavers were found without any variations and anomalies. Where as 9.52% of the lungs of the right side had the absent horizontal fissure pattern and 16.67% Of them were with horizontal fissure that was incomplete on the right side in males. Also 11.90% of the male cadavers had the tubular heart. Conclusion: Lungs develop from the endodermal foregut. The presence of the anomalous fissure pattern and any other anomaly is as a result of the defect in the development of lung during the embryonic life. It is important to study the morphology of the lungs thoroughly before planning for surgical resections of lung and lobectomies so as to avoid the spread of the infection as a result of an anomalous fissure pattern.
