A Cadaveric Study of Morphological Variations of Lung in Vidarbha Region

Knowledge of the position and grade of accessory fissures and lobes is necessary for appreciation of lobar anatomy and thus locating bronchopulmonary segments. Proper understanding of the anatomy of the pulmonary lobes, segments, and fissures allows the surgeon to correlate imaging, pathologic processes, and possible resectional procedures, thus insuring that each patient gets the best possible operation. During the routine dissection variations in major fissures of lung are frequently observed. Taking this into consideration the present study was done to know the prevalence of variations involving lobes and fissures of lung in cadavers of vidarbha region. The study included 50 adult cadaveric lungs obtained from Anatomy dissection hall. The specimens were macroscopically observed for gross morphology of fissures and lobes. Among the right lungs, oblique fissure was incomplete in 5 (17.24 %) lungs. Transverse fissure was incomplete in 9 (31.03 %), absent in 2 (6.89 %) lungs. Accessory fissures were noted in 7 (24.13 %). In the left lung, oblique fissures was incomplete in 6 (28.5 %) and absence of oblique fissure in 1 (4.76 %) lung. Accessory fissures were noted in 4 (19.04 %) lungs. Variational lung anatomy is important in diagnosis and treatment of diseases involving all domains of medicine. Anatomical Knowledge of fissures and lobes is important for CT surgeons, radiologists for interpreting x-rays, CT scans and MRI and is also of academic interest to all medical persons.
