Abstract
- Objective Although repeat microvascular decompression (MVD) for hemifacial spasm (HFS) in patients with failed prior MVD is potentially curative, little is known about the long-term results of repeat MVD. We aimed to evaluate the long-term outcomes and complications after repeat MVD for HFS. Methods We performed repeat MVD on 78 consecutive patients who had undergone a prior MVD >1 year previously. Follow-up data were available for 58 patients, with a median follow-up period of 8.6 years (range, 6.9–10.2 years). The patients were assessed for intraoperative findings, relief results, and complications at discharge and at follow-up, as well as the associations between the preoperative characteristics and outcomes. Results At discharge, of 78 patients with repeat MVD, 72 (92.3%) achieved complete spasm resolution and 1 (2.6%) had significantly improved spasm resolution. Of all patients, 9% (7 of 78) presented short-term complications, including partial hearing loss, hemifacial paresis, and cerebrospinal fluid leak. At follow-up, 45 of 58 (77.6%) patients had complete relief and 10 of 58 (17.2%) had improved relief. Permanent complications occurred in 14 patients (24.1%), with partial hearing loss and mild hemifacial paresis being the most common. Despite the complications, 51 of 58 patients (91.4%) reported an excellent life quality. No significant correlation was found between preoperative characteristics, such as age, interval to prior MVD, or interval to recurrence, and outcomes including short-term or long-term relief results and complications. Conclusions Repeat MVD provides lasting relief for most patients with persistent or recurrent HFS, albeit with a relatively high complication rate. [ABSTRACT FROM AUTHOR]
