Objective　To study the long-term result (over 1 year) of microvascular decompression in the treatment of hemifacial spasm.　Methods　Three hundred and twenty-nine patients with hemifacial pasm were treated with microvascular decompression from July 1986 to June 1999.　Results　In 97 patients followed up for 1-3 years, the cure rate of spasm was 92.7％, the mprovement 3.1%, and no improvenent rate 2.1%. In 77 patients followed up for 3-5 years，the cure rate of spasm was 92.2％ and 34 patients followed up for over 10 years，the cure rate of spasm were 91.2%. The recurrence rate of spasm was 5.2％. The occurrence rate of postoperative complications was 5.5％.　Conclusion　To improve the long efficacy of microvascular decompression hemifacial spasm, it is necessary to avoid injury to the carnial nerves and blood vessel and leaving out responsible blood vessels near hemifacial nerue.
