VARIATION IN LOBES AND FISSURES OF LUNG
Journal Title: International Journal of Anatomy and Research - Year 2018, Vol 0, Issue 1
Abstract
Introduction: Lungs are the paired vital organs meant for respiration situated in the thoracic cavity on either side of the heart. The right lung is divided into supe-rior, middle & inferior lobes by oblique and horizontal fissure. While the left lung is divided into supe-rior & inferior lobes by an oblique fissure. The fissures permit distension of the lobes during respiration. The fissures may be complete, incomplete or absent. Aim: To find out the variations in fissures and lobes along with their patterns, in human lungs; collected from cadavers. Result: Out of 50 right lung specimen, the horizontal fissure was absent in two cases whereas the horizontal fissure was incompletely seen in 18 specimens. Incomplete oblique fissure was seen in 7 right sided lungs. We reported accessory fissures and accessory lobes in 14 specimens. The oblique fissure was absent in 4 left lungs and it was incomplete in 14 lungs. Accessory fissures and lobes were present in 8 specimens. Conclusion: Knowledge of any variations is necessary in performing segmental resection and lobectomy. Accessory fissures indicate persistence of prenatal fissures.
