Delayed facial palsy after microvascular decompression for hemifacial spasm
Delayed facial palsy after microvascular decompression for hemifacial spasm can occur even when hemifacial spasms disappear immediately after microvascular decompression, but the patients with delayed facial palsy can fully recover within weeks 1) 2).
The earlier that DFP develops, the shorter will be the time to recovery 3). Results also suggest that arterial hypertension contributes to DFP 4).
Findings suggested that delayed facial palsy after MVD was caused by a re-activation of varicella zoster virus 5).
The etiology of DFP and its association with herpes infection should be further clarified 6).
