[The progress of stem cells in the treatment of olfactory dysfunction].

Olfactory dysfunction is one of the common diseases in the Department of Otorhinolaryngology. Although the olfactory nerve has ability to regenerate in human central nervous system, if the damage involves nerve, only a few patients can restore the olfactory function. At present, there is no satisfactory treatment for sensorineural olfactory dysfunction. Therefore, it is urgent to explore new and effective method for treating sensorineural olfactory dysfunction. The progress of stem cells in the treatment of olfactory dysfunction is reviewed in this article.
