WITHDRAWN: Corticosteroids for Bell's palsy (idiopathic facialparalysis). Inflammation and oedema of the facialnerve are implicated in causing Bell's palsy. Corticosteroids have a potent anti-inflammatory action which should minimise nerve damage and thereby improve the outcome of patients suffering from this condition.The objective of this review was to assess the effect of steroid therapy in the recovery of patients with Bell's palsy.We searched the Cochrane Neuromuscular Disease Group (...) concealment was appropriate in two trials, and the data reported allowed an intention-to-treat analysis. The data included in the meta-analyses were collected from three trials with a total of 117 patients. Overall 13/59 (22%) of the patients allocated to steroid therapy had incomplete recovery of facial motor function six months after randomisation, compared with 15/58 (26%) in the control group. This reduction was not significant (relative risk 0.86, 95% confidence interval 0.47 to 1.59). The reduction

This presentation can suggest serious neurological disorders, namely subarachnoid haemorrhage, cerebral aneurysms, uncal herniation, or meningitis, so prompt recognition and evaluation is needed. The fourth cranial nerve innervates the superior oblique muscle, which controls depression, intorsion, and adduction of the eye. It is the most common cause of vertical diplopia. The frequency (...) of fourth nerve palsy is difficult to report accurately, but in one large series it was more common than both oculomotor and abducens palsies.

synkinesis. Ten patients presented with both types.This study determined the high prevalence (55.5 percent) of synkinesis in patients with longstanding facialparalysis. Postparalysis synkinesis was positively associated with infectious and idiopathic causes, electrical stimulation, facialnerve decompression, and no requirement for surgery. Postreanimation synkinesis was present in 28.2 percent of reanimated patients and was significantly associated with microsurgical flaps, transfacial nerve grafting (...) analyzed.There was a significant association between cause and surgery. Most patients with facialparalysiscaused by a congenital defect, trauma, or a tumor underwent reanimation. There were no sex- or synkinesis-related differences in the doses used, but the doses were higher in the reanimation group than in the no-surgery group. Synkinesis was found in 196 patients; 148 (41.9 percent) presented with postparalysis synkinesis (oro-ocular, oculo-oral) and 58 (16.4 percent) presented with postreanimation
Diabetic Mice Show an Aggravated Course of Herpes-Simplex Virus-Induced FacialNerveParalysis. Bell's palsy is highly associated with diabetes mellitus.The cause of Bell's palsy in diabetes mellitus is not completely understood. Diabetic mononeuropathy or reactivation of herpes simplex virus type 1 (HSV-1) may be responsible for the facialparalysis seen in diabetic patients. We previously reported transient and ipsilateral facialparalysis in mice inoculated with HSV-1. In this study, we (...) increased in the diabetic mice. Electrophysiologic examinations and histopathologic changes also revealed that the facialnerve damage was more severe in the diabetic group.The aggravated course of HSV-1 infection in diabetes suggests that HSV-1 may be the main causative factor for the increased incidence of facialparalysis in diabetic patients.
Modified Stennertâ€™s Protocol in Treating Acute Peripheral FacialNerveParalysis: Our Experience The aim of this study was to know the effect of modified Stennert's protocol on Bell's palsy and delayed onset post traumatic facialnerveparalysis. Retrospective study method which included 26 patients was done. Of this 19 patients had Bell's palsy and seven patients had delayed onset post traumatic facialnerveparalysis. All patients started on modified Stennert's protocol. Nineteen patients (...) were observed and had idiopathic facialnerveparalysis. Fifteen patients showed clinical improvement by the 10th day and by the end of 1 month, 18 patients showed significant symptomatic improvement. One patient had residual defects at 6 months. Of the seven patients with delayed onset post traumatic facialnerveparalysis, three patients had to undergo facialnerve decompression, the remaining four receiving only modified Stennert's protocol. Improvement was seen in three patients by the 10th day
Hemihypoglossal nerve transfer for acute facialparalysis. The authors have developed a technique for the treatment of facialparalysis that utilizes anastomosis of the split hypoglossal and facialnerve. Here, they document improvements in the procedure and experimental evidence supporting the approach.They analyzed outcomes in 36 patients who underwent the procedure, all of whom had suffered from facialparalysis following the removal of large vestibular schwannomas. The average period (...) of paralysis was 6.2 months. The authors used 5 different variations of a procedure for selecting the split nerve, including evaluation of the split nerve using recordings of evoked potentials in the tongue.Successful facial reanimation was achieved in 16 of 17 patients using the cephalad side of the split hypoglossal nerve and in 15 of 15 patients using the caudal side. The single unsuccessful case using the cephalad side of the split nerve resulted from severe infection of the cheek. Procedures using

Profile of facial palsy in Arar, northern Saudi Arabia The term facial palsy generally refers to weakness of the facial muscles, mainly resulting from temporary or permanent damage to the facialnerve. Common causes of facialparalysis include infection or inflammation of the facialnerve, head trauma, head or neck tumor, stroke.To outline the incidence of several etiologies and the profile of patients with peripheral facialparalysis attending the outpatient clinic of the neurology department (...) in Hospitals of Arar City, Saudi Arabia.This cross-sectional study was carried out in Arar city from October 2016 to May 2017. The study was conducted in the outpatient clinic of the neurology department in hospitals of Arar City. Any ages of both sexes of all newly diagnosed unilateral facial palsy were included in the study. Data were analyzed by SPSS version 15, using descriptive statistics and Chi-square test. P-value was considered significant if <0.05.The mean age of the facial palsy cases was 33.65
patients completed a minimal follow up of 24 months at the time of evaluation and were included in the study population.

The most common cause of facialparalysis was vestibular Schwannoma surgery. All the patients achieved a postoperative HB grade III or IV after a mean follow-up time of 20 months.

Only 4 patients suffered from difficulties during eating and drinking and three of them had associated lower cranial nerve deficit.

Polytetrafluoroethylene granuloma-associated facial palsy following microvascular decompression. Microvascular decompression (MVD) may be employed in the management of hemifacial spasm (HFS), wherein a pledget of polytetrafluoroethylene (i.e., Teflon, Chemours, Wilmington DE) is sometimes introduced to separate an offending vessel from the cisternal segment of facialnerve. Rarely, Teflon may cause a granulomatous reaction resulting in nerve palsy. We here present the first case series (...) of facial palsy thought to be secondary to Teflon granuloma following MVD for HFS.A data repository of 1,312 patients with facial palsy was reviewed to identify individuals who had previously undergone MVD for HFS. Data collected include age at time of MVD, age at onset of facial weakness and at presentation, House-Brackmann scores, clinician-graded facial function using the Electronic FacialParalysis Assessment scale, imaging findings, and therapeutic interventions and outcomes.Six patients meeting

Facialnerve palsy after reactivation of herpes simplex virus type 1 in diabetic mice. Bell's palsy is highly associated with diabetes mellitus (DM). Either the reactivation of herpes simplex virus type 1 (HSV-1) or diabetic mononeuropathy has been proposed to cause the facialparalysis observed in DM patients. However, distinguishing whether the facial palsy is caused by herpetic neuritis or diabetic mononeuropathy is difficult. We previously reported that facialparalysis was aggravated in DM (...) mice after HSV-1 inoculation of the murine auricle. In the current study, we induced HSV-1 reactivation by an auricular scratch following DM induction with streptozotocin (STZ).Controlled animal study.Diabetes mellitus was induced with streptozotocin injection in only mice that developed transient facialnerveparalysis with HSV-1.
