title: Hemifacial spasm: report of nine cases treated by posterior fossa microsurgical decompression.
abstract: Nine cases of hemifacial spasm have been treated, in our department until 1979, by posterior fossa microsurgical decompression, as described by Jannetta, without mortality or significant postoperative complications. A blood vessel was found crossing or looping the facial nerve in 8 cases. The relief of hemifacial spasm was immediate and complete in 7 cases, and partial in 1 case. This technique seems to be an effective and safe treatment, in this particular disease.
