Being the essential organs of respiration, pair of lungs are situated on either side of the mediastinum. Each lung is divided into lobes by the fissures. These fissures allow for proper expansion of lungs and on the other hand fissures may have a role in restricting infection to a particular lobe. Fissures may be complete, incomplete or absent.To study the variations in the fissures of lung, compare the results with the available data and to discuss the surgical importance of this study. 37 pairs of lungs (37 right and 37 left) from formalin fixed cadavers were observed and classified into different grades of fissures ( as per Craig and Walker criteria). Presence of accessory fissures was noted.Out of the 37 right lungs, 3 showed absence of horizontal fissure and the same fissure was incomplete in right sided 17 lungs. Among the left lungs, 9 had incomplete oblique fissure. Accessory fissure were found in 2 right and 1 left lungs.The current study showed that right lung may be without horizontal fissure or fissures may be incomplete. Thus, a light on these variations by the cardiothoracic surgeons will help in better planning of surgeries like lobectomy. Knowledge about the fissures will aid in arriving at better diagnosis for the clinicians and radiologists.
Background: Wormian bones, also called as sutural bones, are small bones found in the sutures of skull. These bones may be found as normal variants in the skull or may be associated with some of the congenital abnormalities. Materials and Results: In our study, done on 110 dry adult human cadaveric skulls, we have identified 76 skulls with wormian bones (69.09%). Highest number of wormian bones was at the lambdoid suture, with 50.04% and next at the lambda, with 9%. Conclusion: The current study on wormian bones will add further knowledge to the available data about wormian bones and it will be of help for neurosurgeons, orthopedic surgeons, pediatricians, radiologists and anthropologists for proper diagnostic and therapeutic purposes.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
