Objective
Microvascular decompression (MVD) has become the standard treatment for hemifacial spasm. As not all patients get complete relief, this strategy is still controversial. The study aimed to figure out how to tell the proper endpoint to the surgery.
Methods
A series of 356 consecutive patients with hemifacial spasm were enrolled in this study. All patients fell into two groups according to the period they presented. Two different criteria (simple criterion vs. complex criterion) to end an operation were applied respectively. The intra-operative finding, results and complications of these two groups were compared. The advantage of the complex criterion was analyzed.
Results
The group which used complex criterion got better results than the group which used simple criterion. The complex criterion which combines full-length evidence, vascular evidence and electrophysiological evidence proved to be reliable to tell the proper endpoint to the surgery.
Conclusion
MVD operations can be ended only after the full-length evidence, vascular evidence and electrophysiological evidence are all present.
