Abstract:
BACKGROUNDHemifacial spasm (HFS) is a facial nerve disorder characterized by episodic involuntary ipsilateral facial muscle contraction. Information on Chinese patients with HFS has not been well-characterized. This study aimed to evaluate the clinical feature and the treatment status of HFS across China.
METHODSA cross-sectional study including 1003 primary HFS patients had been carried out in 15 movement disorder clinics in China in 2012. The investigated information was acquired from questionnaires and medical records including demographic data, site of onset, aggravating and relieving factors, treatments prior to the investigation, etc.
RESULTSIn this study, the ratio of male to female was 1.0:1.8, the mean age at onset was (46.6 ± 11.5) years. About 1.0% patients were bilaterally affected. The most often site of initial onset was the orbicularis oculi muscle. The most often affected sites were orbicularis oculi, zygomatic, and orbicularis oris muscles. Stress/anxiety and relaxation were most often aggravating and relieving factors, respectively; 2.3% patients had family history, 28.4% cases were combined with hypertension, and 1.4% patients were with trigeminal neuralgia. Botulinum toxin type A (BTX-A) injection was the most commonly used treatment, followed by acupuncture and oral medication. BTX-A maintained the highest repeat treatment ratio (68.7%), while 98.4% patients gave up acupuncture. The mean latency of BTX-A effect was (5.0 ± 4.7) days, the mean total duration of the effect was (19.5 ± 11.7) weeks, and 95.9% patients developed improvements no worse than moderate in both severity and function. The most common side effect was droopy mouth.
CONCLUSIONSThe onset age of HFS in China is earlier than that in western countries. The most often used two treatments are BTX-A injection and acupuncture, while the latter kept the poor repeat treatment ratio because of dissatisfactory therapeutic effect.
