TO THE EDITOR: I appreciate the authors' brief review on Bell palsy, but I am curious why they did not mention the benefits of acupuncture for treating this condition.1,2 Before reaching for my prescription pad to prescribe steroids, I refer my patients to one of the many qualified and licensed acupuncturists in my area. These patients often achieve dramatic improvements without the adverse effects that commonly occur with steroid use (e.g., weight gain, worsening of blood glucose control).
IN REPLY: Acupuncture has a growing evidence base, and further research is warranted. Current evidence indicates that early treatment with prednisolone significantly improves chances of complete recovery from Bell palsy1; therefore, steroid treatment should not be delayed to initiate acupuncture or any other alternative therapy. There are no evidence-based recommendations for the initiation of acupuncture for Bell palsy.2 A Cochrane systematic review found no harm from acupuncture, but also could not establish effectiveness secondary to the poor quality and insufficient power of existing studies.3
Most patients with Bell palsy achieve dramatic improvements without any treatment. In one study evaluating 1,011 patients, 85% showed signs of remission within a three-week period.4 The primary purpose of steroid therapy is to prevent long-term sequelae, and there is a higher degree of success if it is initiated as soon as possible.5
