Introduction: Olfactory loss in patients with chronic rhinosinusitis has been measured by different methods. However, the results have been variable, and it is not clear whether endoscopic sinus surgery significantly improves olfactory function. This study was performed to evaluate the influence of endoscopic sinus surgery on olfactory function in patients with chronic rhinosinusitis.  Material...

The sense of olfaction reached its zenith in development much earlier than other special senses. Olfaction is much more acute than the other senses, exhibits both high sensitivity for odours and high discrimination between them. This plays a very important role even in the social and behavioral aspects of human beings. Recent studies using molecular genetics, electrophysiology and behavioral an...

Olfaction is typically described as behaviorally slow, suggesting neural processes on the order of hundreds of milliseconds to seconds as candidate mechanisms in the creation of olfactory percepts. Whereas a recent study challenged this view in suggesting that a single sniff was sufficient for optimal olfactory discrimination, a study by Abraham et al. in this issue of Neuron sets out to negate...

OBJECTIVES Results of butanol threshold tests (BTTs) have shown that birhinal olfaction tends to converge toward monorhinal olfaction of the dominant nostril. However, birhinal olfaction may also be worse than dominant-side monorhinal olfaction. The goal of our study was to investigate the effect of deviated nasal septum on birhinal olfaction in patients with lateralized olfaction and to examin...

Introduction Since the origin of life in the primordial soup, the survival of all organisms has depended on their ability to detect and respond to chemicals in their environment. Today, animal chemosensation— smell and taste—relies on sensory circuits that recognize diverse external chemical cues and transform them into precise patterns of neuronal activity to evoke the appropriate response (Ac...

nor constipation. He continued his usual diet, though in smaller quantities. A fortnight later, he suddenly found a little pus and some greenish yellow semi-solid matter of fsecal smell escaping from an opening in the swelling above. This' discharge gave him a little relief. Subsequently he observed that the continuous discharge above the scrotum was irritating the skin and preventing his work....
