Summary
Reoperation for recurrent or residual hemifacial spasm (HFS) after microvascular decompression (MVD) surgery is effective. Identifying the cause, such as missed vessels or material issues, is key to successful outcomes, though complication rates are higher.
Area of Science:
- Neurosurgery
- Neurology
Background:
- Microvascular decompression (MVD) is the primary curative treatment for hemifacial spasm (HFS).
- Recurrent or residual HFS cases often receive less attention, necessitating further investigation into their causes and treatment efficacy.
Purpose of the Study:
- To investigate the potential etiologies of recurrent and residual hemifacial spasm (HFS) cases.
- To evaluate the effectiveness and outcomes of reoperation for patients with recurrent or residual HFS.
Main Methods:
- Retrospective review of 28 patients who underwent reoperation for HFS.
- Analysis of intraoperative findings, including missed culprit vessels, Teflon adhesion, and improper material application.
- Assessment of surgical outcomes and complications following reoperation.
Main Results:
- Seventeen patients had missed culprit vessels or insufficient decompression at the root exit zone (REZ).
- Eight patients experienced Teflon adhesion, and three had improper decompression material application.
- Reoperation resulted in 17 excellent, 7 good, and 4 fair outcomes, with an 8/28 (28.57%) complication rate.
Conclusions:
- Reoperation for recurrent/residual HFS is an effective treatment option with a high cure rate.
- Accurate identification of the REZ and appropriate decompression techniques are crucial for successful reoperation.
- While effective, reoperation carries a higher complication risk compared to the initial MVD surgery.
