Recurrent Hemifacial Spasm following Minor Trauma: Report of a Case

Microvascular decompression (MVD) has been accepted worldwide as a reasonable treatment for hemifacial spasm (HFS); however, resolution of the HFS is often gradual. To conclude the delayed relief rate of the MVD for the treatment of HFS, we conducted a systematic review. Using the keywords delayed relief, hemifacial spasm, or microvascular decompression, articles published in English-language journals and indexed in PubMed between June 1, 1994 and June 1, 2014 on the treatment of HFS with emphasis on delayed relief were considered for this study. Twelve articles with 2727 patients with HFS were finally enrolled in this review. Among all the patients, the ratio of male versus female was 1:2.7, and left versus right was 1:1.6. The average age at surgery was 52.5 years (49.1-55.9 y), with HFS symptom duration of 68.4 months (38.4-98.4 mo) before the surgery. The average follow-up duration was 49 months (6.4-121.6 mo). After examining all the patients, we obtained a mean postoperative success rate of 85.1% (76.5%-93.5%), but the success rate after the MVD immediately is only 71.8% (59.5%-84%). The mean rate of delayed relief was 25.4% (18.8%-37.1%). Approximately 13.1% (5.9%-19.7%) of the patients with symptom recurrence resorted to repeated MVD during the follow-up period. Accordingly, MVD is the most effective treatment for patients with HFS, but some of the patients may experienced delayed relief, which could be avoided if a thorough decompression of the facial nerve root had been obtained.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
