About Bell’s Palsy
Each year in the UK, around 1 in 5,000 people develop Bell’s palsy, which is characterised by unilateral facial weakness of rapid onset (Rowlands 2002,Holland 2004). The condition can develop at any age, but seems to be most common in those aged between 15 and 60 years (Peitersen 1982). In about 71% of patients, it resolves spontaneously without treatment, but 13% are left with slight facial weakness and 16% with moderate to severe weakness that results in major facial dysfunction and disfigurement (Peitersen 1982, Peitersen 2002, Ikeda 2005). Bell’s palsy is due to inflammation of the facial nerve in the internal auditory canal, but the cause of the inflammation is unknown (Adour 1972, Gacek 2002). The condition results in an isolated unilateral lower motor neurone palsy, with impairment of all facial movements on the affected side, including blinking. Conventional medical treatment includes eye protection, drugs (i.e. corticosteroids, antivirals), surgery and physiotherapy.

How acupuncture can help you
Clinical trials suggest that acupuncture is at least as effective as corticosteroids and may improve recovery in patients with Bell’s palsy, either used alone or in combination with drug treatment (Tong 2009; Li 2004). Note though that most of the trials to date have been of poor quality which allows only tentative conclusions to be reached (Chen 2010). (See Table overleaf) Acupuncture may help in the treatment of Bell’s palsy by:
- reducing inflammation, by promoting release of vascular and immunomodulatory factors (Kim 2008, Kavoussi 2007, Zijstra 2003);
- enhancing local microcirculation, by increasing the diameter and blood flow velocity of peripheral arterioles (Komori 2009);
- • nerve and muscular stimulation (Cheng 2009).
About traditional acupuncture
Acupuncture is a tried and tested system of traditional medicine, which has been used in China and other eastern cultures for thousands of years to restore, promote and maintain good health. Its benefits are now widely acknowledged all over the world, and in the past decade traditional acupuncture has begun to feature more prominently in mainstream healthcare in the UK. In conjunction with needling, the practitioner may use techniques such as moxibustion, cupping, massage or electroacupuncture. They may also suggest dietary or lifestyle changes.
Traditional acupuncture takes a holistic approach to health and regards illness as a sign that the body is out of balance. The exact pattern and degree of imbalance is unique to each individual. The traditional acupuncturist’s skill lies in identifying the precise nature of the underlying disharmony and selecting the most effective treatment. The choice of acupuncture points will be specific to each patient’s needs. Traditional acupuncture can also be used as a preventive measure to strengthen the constitution and promote general wellbeing.
An increasing weight of evidence from Western scientific research (see overleaf) is demonstrating the effectiveness of acupuncture for treating a wide variety of conditions. From a biomedical viewpoint, acupuncture is believed to stimulate the nervous system, influencing the production of the body’s communication substances - hormones and neurotransmitters. The resulting biochemical changes activate the body's self-regulating homeostatic systems, stimulating its natural healing abilities and promoting physical and emotional wellbeing.
