Olfactory Disorder Clinical Trial
Official title:
The Efficacy of Traditional Chinese Medicine in Olfactory Dysfunction: A Randomized Controlled Trial
Studies have demonstrated that patients with olfactory dysfunction could improve the olfactory function after olfactory training. But the efficacy of Traditional Chinese Medicine is unknown.The purpose of this study is to evaluate its efficacy in olfactory dysfunction.
A recent meta-analysis found significant positive effects of olfactory training on the individual subcomponents of odor threshold, discrimination, identification, and the composite TDI score. In addition to the evidenced improvement in olfactory function after olfactory training, this form of treatment carries very little risk of adverse effects, is cheap, and can be administered by the patient. For these collective reasons, olfactory training is an attractive treatment modality. Chinese experts consensus on diagnosis and treatment of olfactory dysfunction in 2017 shown that some evidences proved that Traditional Chinese Medicine treatment would benefit olfactory dysfunction but the evidences is not adequate. Until now, the efficacy of Traditional Chinese Medicine is controversial. This study investigate the efficacy and the safety of Traditional Chinese Medicine and olfactory training as a treatment for patients with olfactory dysfunction. ;
