Should acupuncture therapy be used for acute facial paralysis? A protocol of systematic review

Abstract Introduction Peripheral Facial paralysis (PFP) results in functional and social dysfunction, when it is under a severe condition at onset, long-term poor outcomes do occur. Different acupuncture method has been reported to be potentially effective for shortening the disease course and reduce the occurrence of sequelae when applying at an early stage. Neuroedema is a common pathological feature in the acute phase, many clinical studies have suggested its effect of reducing facial nerve edema. It is of value to estimate the effectiveness and safety of acupuncture treatment at the onset, and it is worthwhile to assess the most suitable acupuncture method for the acute period. Methods and analysis We will include all the RCTs and quasi-RCTs on acupuncture therapy for PFP at its acute stage. Literature searching will be conducted until September 15th, 2020 from eight databases systematically. Two reviewers will screen the literature and extract the data independently. RevMan software and the Cochrane tool of Risk of Bias will be used to assess the methodological quality of RCTs. Forest plots and summary findings will be generated. If data permits, a meta-analysis will be conducted. Ethics and dissemination Since this study will not involve clinical treatment of patients, ethics approval is not required. The result of this study will be submitted to a peer-reviewed journal for publication and as a proposal for clinical practice and further study on acupuncture treatment at the early stage of PFP. Discussion This review will summarize the evidence on the different type of acupuncture therapy for acute bell’s palsy and Ramsay-Hunt syndrome. We anticipate that it would be safe and effective when applying to the acute phase of PFP, and some specific suitable acupuncture methods would be found resulting from this review.Trial registration number International Prospective Register for Systematic Reviews (PROSPERO) number CRD42020205127
