Background and aim: The anatomical variations of fissures and lobes of lungs have been described by many research workers on CT scans, whereas, there were fewer studies done on gross anatomical specimens. Materials and methods: In the present study, 30 embalmed cadavers have been dissected and lungs were examined for fissures and lobes. Results: Nine out of 30 left lungs showed incomplete oblique fissures. Eight out of 30 right lungs showed incomplete transverse fissure but oblique fissure was complete, and in two right lungs, incomplete oblique and transverse fissures were found. In one cadaver one accessory lobe and one accessory fissure was present, on right side. Comparative analysis of present work with data in literature suggest that different studies performed on radiological images reported greater prevalence of incomplete or absence of pulmonary fissures as compared to present cadaveric study. Therefore our findings with regard to fissures and lobes are different from many studies but are approximately similar to two. Conclusion: Variation of lung anatomy is important for cardio-thoracic surgeons, radiologists for interpreting x-rays, CT scans and MRI and also it is of academic interest to all medical persons.
