Reference work entry


Neurosensory disorders are a group of conditions characterized by abnormal perception by the afferent nerves supplying the taste receptors, olfactory epithelium, and other areas of the face and jaw. This chapter will focus on neurosensory disorders including smell and taste. Smell and taste are an integral part of our everyday function as humans. Both smell and taste are essential to experience “flavor” of foods. They also have an important protective role in warning the individual of any possible harm such as a “gas leak” or “spoilt food.” Other neurosensory conditions such as anesthesia, hypoesthesia, paresthesia, and Bell’s palsy will also be discussed. Management of these neurosensory disorders is often challenging as the currently available treatments are effective in some cases, and partially effective or ineffective in other cases. Understanding these neurosensory disorders, in particular the differences between the various types of disorders, will enable the clinician to provide better treatment modalities to the patient.
