Nine cases of hemifacial spasm have been treated by posterior fossa exploration without mortality or significant morbidity. In only three was definite pathology found, but the hemifacial spasm was abolished in eight patients and markedly diminished in the remaining patient. The condition has reccurred in one patient. Microsurgical techniques make the operation safe and accurate. We suggest that this procedure is the best approach for hemifacial spasm requiring treatment. Where no definite pathology is found, the effectiveness of the procedure is probably due to fibrosis and hence mild trauma to the facial nerve induced by the sponge wrapped around the nerve.
9例半面痉挛患者接受了后颅窝探查术治疗，无死亡病例，也无明显的严重并发症。仅3例发现明确的病理改变，但8例患者的半面痉挛症状消失，其余1例患者症状明显减轻。有1例患者病情复发。显微外科技术使手术安全且精确。我们认为，该手术方法是治疗半面痉挛的最佳途径。在未发现明确病理改变的情况下，该手术的有效性可能归因于纤维化，即包裹在面神经周围的海绵对面神经造成的轻度损伤。
