Clinical analysis of repeat microvascular decompression for recurrent hemifacial spasm

Area of Science:

• Neurosurgery
• Neurology

Background:

• Recurrent hemifacial spasm (HFS) presents challenges after initial treatment.
• Microvascular decompression (MVD) is a primary surgical intervention for HFS.

Purpose of the Study:

• To evaluate the efficacy and safety of repeat microvascular decompression (MVD) for patients with recurrent hemifacial spasm (HFS).

Main Methods:

• Retrospective analysis of 13 patients who underwent repeat MVD for recurrent HFS.
• Review of clinical data, surgical findings, outcomes, and complications.

Main Results:

• Repeat MVD successfully treated HFS in all patients.
• Teflon felt packing and vascular changes were primary causes of recurrence.
• 84.6% of patients achieved complete or major spasm alleviation post-repeat MVD.
• Transient facial weakness occurred in 15.4% of patients, with no serious morbidities.

Conclusions:

• Repeat MVD is a safe and effective treatment option for recurrent hemifacial spasm.
• Addressing factors like Teflon felt and vascular compression is crucial for successful repeat MVD.
