Abstract

To study the role of herpes virus reactivation in the onset of more than three days-delayed facial paralysis (FP) following vestibular schwannoma (VS) surgery and advocate a specific medical management. Retrospective study on 8 cases from a series of 348 patients operated on of a VS between 1996 and 2002. Seven of the eight patients were given intravenously acyclovir (30 mg x kg(-1) x d(-1) for 5 days) and methyl-prednisolone (2 mg x kg(-1) x d(-1) for 7 days). A serologic testing looking for specific anti-herpes simplex viruses type 1 and 2 (HSV-2) and varicella-zoster virus (VZV) antibodies at the onset of the FP and 2 weeks later could be done in only 3 cases. Mean delay of FP onset was 8.75 days. Mean time for recovery with intravenous treatment was 90 days. All treated patients had a House and Brackmann grade 1 recovery. The last one had only a grade 3 after 400 days of evolution: he could not be treated because of postoperative transient psychiatric problems. Serologic testing revealed in those patients in whom it could be done either a high level of anti-HSV or -VZV antibodies at the time of onset or a dramatic increase in anti-HSV or anti-VZV antibodies between the two samples, strongly suggesting a HSV or VZV reactivat...Continue Reading
