This article analyzes the current status of the researches on acupuncture-moxibustion for idiopathic facial palsy (Bell's palsy). Acupuncture-moxibustion is widely applied in treatment of Bell's palsy and the relevant researches are enriched. But the hierarchical discussion on the effectiveness is reported inadequately. Consequently

the necessity and advantages of acupuncture-moxibustion are hardly prominent. Besides

the safety of acupuncture-moxibustion in treatment is not fully explored. The common shortcomings are presented in professional study and statistical designs

and the quality of the evidences is not high. The recommendation strength of acupuncture-moxibustion is weak in international guidelines. The crucial questions are not deeply discussed

and there are lack of the recognized optimal protocol in clinical practical guidelines. It is suggested that the researches should improve the evaluation of the disease itself that may affect the prognosis of Bell's palsy

such as location

conditions and duration of illness

basic diseases and syndrome/pattern differentiation. The effect of acupuncture-moxibustion should be verified hierarchically

the questions on safety should be emphasized

the quality of study should be improved

the staging of treatment should be specified and the effect of acupuncture-moxibustion should be evaluated in multi-dimensions

and the elements of acupuncture-moxibustion should be optimized systematically in the aspects of timing

acupoint selection

needle devices

manipulation

intervention measures and regimen composition. So as to promote the research of acupuncture-moxibustion for Bell's palsy to a new process.
