Anatomical study on variations of fissures of lung

Abstract

Aim: This study is conducted to record the variations in fissures and lobes of lung which will be helpful for all clinicians and also of academic interest. Materials and Methods: The study was undertaken in 25 pairs of cadaveric specimens. The lungs were exposed to study the morphological features like number, fissures and lobes. Presence of anatomical variations was observed and photographed. Results: 11 right side lungs showed incomplete horizontal fissure. In 5 right lungs there was no horizontal fissure. Incomplete oblique fissure was found in 7 right lungs. 2 right lungs did not have any fissures. 8 left lungs exhibited incomplete oblique fissure. Conclusion: A detailed knowledge of the anatomy of the fissures of lung is essential for the proper interpretation of radiological images like X- ray, CT scan and MRI for the radiologists, cardiothoracic surgeons performing lobectomies, and segmental resections. Furthermore, the knowledge of fissures and lobes of lungs is important for the surgeons to properly manage the potential problems which may be encounterd during surgery.
