RESUMO
It's a small wonder. Yes, nanotechnology is already touching our lives for better. The recent progress in the field of medicine has been phenomenal. None could have ever imagined that the Nanotechnology would have such a promising and extensive application in medical sciences. Right from developing newer therapeutics and imaging techniques to targeted drug delivery you can name it all. Nanotechnology science is still in its nascent stage with a long way to go. A nanometer is a billionth of a meter. Manipulation of matter on a very small scale is Nanotechnology and its utilization in medicine is Nanomedicine. In fact in recent times no other branch has seen the amalgation of such varied disciplines including physicists, chemists, engineers and biologists. Nanotechnology is still a very nascent science. It needs to grow and as its grows its true virtues and vices would come to fore. At the most now we can say that it has a very promising future. The genesis of nanotechnology can be traced to the promise of revolutionary advances across medicine, communications, genomics and robotics.
RESUMO
Aim: The paranasal sinuses are subject to large variety of lesions. Congenital malformations and normal anatomic variations are important in this region To find out prevalence of frontal sinus aplasia in normal healthy population and to discuss its clinical importance. Materials and Methods: A cross-sectional analysis is performed on CT scans of head & neck region of patients visiting Radio-diagnosis Department of Era’s Lucknow Medical College. Results: Frontal sinus aplasia was observed in 6.6% of target population. Conclusion: It is important for surgeons to be aware of variations in sinuses that may predispose patients to increased risk of intraoperative complications and help avoid possible complications and improve success of management strategies.
