Progress in treatment of facial neuritis by acupuncture combined with medicine from the perspective of modern medicine: A review

Facial neuritis is a common clinical disease with high incidence, also known as Bell palsy or idiopathic facial nerve paralysis, which is an acute onset of peripheral facial neuropathy. In modern medicine, there have been obstacles to the effective treatment of facial neuritis. At present, the clinical use of Western medicine treatment is also a summary of clinical experience, the reason is that the cause of facial neuritis is unknown. Facial neuritis belongs to the category of "facial paralysis" in traditional Chinese medicine. For thousands of years, Chinese medicine has accumulated a lot of relevant treatment experience in the process of diagnosis and treatment. At the same time, traditional Chinese medicine, acupuncture and the combination of acupuncture and medicine play an important role in the treatment of facial neuritis. This article discusses the treatment of facial neuritis with acupuncture combined with Chinese medicine, based on the research progress of modern medicine. In this review, we provide an overview of the effectiveness of acupuncture and medication combinations and facial neuritis with current studies investigating acupuncture and medication combinations in the treatment of facial neuritis.

The Diagnosis and Treatment of Idiopathic Facial Paresis (Bell's Palsy)

BACKGROUND

Peripheral facial nerve palsy is the most com- mon functional disturbance of a cranial nerve. 60-75% of cases are idiopathic.

METHODS

This review is based on a selective literature search proceeding from the current, updated German-language guideline on the diagnosis and treatment of idiopathic facial nerve palsy.

RESULTS

The recommended drug treatment consists of prednisolone 25 mg bid for 10 days, or 60 mg qd for 5 days followed by a taper to off in decrements of 10 mg per day. This promotes full recovery (number needed to treat [NNT] = 10; 95% confidence interval [6; 20]) and lessens the risk of late sequelae such as synkinesia, autonomic disturbances, and contractures. Virostatic drugs are optional in severe cases (intense pain or suspicion of herpes zoster sine herpete) and mandatory in cases of varicella-zoster virus (VZV) infection. Corneal protection with dexpanthenol ophthalmic ointment, artificial tears, and a nocturnal moisture- retaining eye shield has been found useful in practice. In cases of incomplete recovery with residual facial weakness, both static and microsurgical dynamic methods can be used to restore facial nerve function.

CONCLUSION

Because 25-40% of cases of facial nerve palsy are not idiopathic, differential diagnosis is very important; key diagnostic methods include a clinical neurological examin- ation, otoscopy, and a lumbar puncture for cerebrospinal fluid examination. High-level evidence supports corticosteroid treatment for the idiopathic form of the disorder.
