Abstract
PURPOSE To investigate the effect of Bell's palsy (BP) presenting as polycranial neuropathy (PCN) compared with BP caused by isolated facial nerve (CNVII). METHODS We carried out a retrospective cohort study of the medical records of all consecutive patients who were diagnosed with BP at a single tertiary referral center between 2010 and 2017. Included were patients 18 years or older who were clinically diagnosed with BP and completed 7 days of systemic steroidal treatment and at least 6 months of follow-up. The patients were divided into two groups according to whether the BP derived from a monocranial neuropathy or a PCN. Demographics and BP severity and outcome were compared between these groups. A systematic literature review using Medline via "PubMed," "Embase," and "Web of Science" was conducted. RESULTS In total, 321 patients with BP were enrolled. The median (interquartile range) age at presentation was 44 (33-60) years. Sex distribution showed male predominance of 57.6% (n = 185) versus 42.4% (n = 136), and 21.2% (n = 68) had PCN. The most concomitantly affected cranial nerve (CN) was the trigeminal (CNV; n = 32, 47%), followed by the glossopharyngeal nerve (CNIX; n = 14, 21%) and the audiovestibular nerve (CNVIII; n = 10, 15%). Age, House-Brackmann score on presentation, and diabetes mellitus (DM) were independent predictors for PCN etiology ( p = 0.001, p = 0.034, and p < 0.001, respectively). Each increase in 1 year of age was associated with additional odds ratio (95% confidence interval) of 0.97 (0.95-0.99) for PCN. The odds ratio (95% confidence interval) associated with DM was 8.19 (4.02-16.70). Our systematic literature review identified 1,440 patients with the PCN type of BP. The most commonly affected CN was the trigeminus (25-48%), followed by the glossopharyngeal and audiovestibular nerves (2-19% and 0-43%, respectively). CONCLUSION The severity of facial weakness on initial presentation among PCN patients was significantly higher compared with the monocranial neuropathy-type BP patients. The authors believe that the significant association and prevalence rate ratio between DM and PCN warrant that a patient presenting with PCN undergo screening for DM.

Abstract
OBJECTIVE To investigate the surgical outcomes in patients treated for recurrent facial nerve palsy (RFP) at a quaternary facial nerve referral center. METHODS A retrospective chart review was performed on 132 patients with RFP who presented to our institution's facial nerve clinic from 2001 to 2021. Records were analyzed for etiology of palsy, facial nerve function, and recurrence rates. Pre- and post-operative audiometric outcomes were also assessed in surgically managed patients. RESULTS 6.8% of RFP patients underwent surgical decompression. For patients who did not undergo surgery, the House-Brackmann (HB) score was 2.9 ± 1.3 (SD) at the initial clinic visit, and 2.4 ± 1.3 (SD) at the last clinic visit. This difference was significantly different (p = 0.01, t-test). For surgical patients, the pre-operative HB score was 2.9 ± 0.9 (SD) and post-operative HB score was 1.8 ± 0.6 (SD), which were significantly different (p = 0.01, t-test). The number of facial palsy episodes also decreased pre- and post-operatively from 3.5 ± 0.8 (SD) to 0.2 ± 0.4 (SD) episodes, which were significantly different (p < 0,001, t-test). Audiometric outcomes were not significantly different pre- and post-surgery (p = 0.31, t-test for PTA; p = 0.34, t-test for WRS). CONCLUSION Facial nerve decompression for RFP patients with incomplete functional recovery may be an effective treatment for decreasing the frequency and severity of facial palsy episodes. LEVEL OF EVIDENCE 4 Laryngoscope, 133:1222-1227, 2023.

Abstract
BACKGROUND In the Division of Pediatric Neurology at the University Medical Center Göttingen we observed that many patients with Bell palsy are overweight or obese. To evaluate whether overweight and obesity are associated with increased risk of Bell palsy in children we conducted this single-centered retrospective study by performing a database search for International Classification of Diseases (ICD)-10 primary and secondary diagnosis of G51.0 (facial nerve palsy) between January 1, 2010, and December 31, 2020. METHODS For risk assessment, patients' body mass indices (BMIs) were compared with BMI data of controls from a nationwide child health survey. RESULTS In total, 202 patients with peripheral facial nerve palsies (pFPs) were included, of which nearly half were classified as Bell palsies; 38% and 24% of the patients with Bell palsy and pFP had a BMI above the 90th percentile, respectively. High BMI was associated with statistically increased odds of Bell palsy in the group of overweight and obese patients (BMI >90th percentile; odds ratio [OR], 2.42; 95% confidence interval [CI], 1.6 to 3.8; P < 0.001) and solely obese patients (BMI >97th percentile; OR, 2.43; 95% CI, 1.4 to 4.3; P = 0.003). CONCLUSIONS We could confirm our observation that overweight and obesity are associated with increased risk of Bell palsy in children.

Abstract
Cranial nerve VII palsy is one of the most common cranial nerve pathologies seen in clinical practice. In the vast majority of cases, the cause is thought to be idiopathic and is also referred to as Bell's palsy. These cases are normally self-limiting and often treated with a short course of corticosteroids for symptom management. However, prompt work-up and diagnosis are crucial, as non-idiopathic causes can often be life-altering and necessitate prompt intervention. Here, we report a unique case of a 43-year-old immigrant male who presented to the emergency department with a three-day history of worsening facial droop and slurred speech, with associated facial pain, headaches, and dizziness for the previous week. On exam, there was stark right facial weakness involving both the upper and lower portions of the face with no sensory deficits. The patient's right eye was erythematous and painful, with no ability to fully open or close the right eyelid. The initial workup showed minor transaminitis with pancytopenia. A thorough workup was initiated, and all testing and serology were normal, with the exception of initial HIV screening. This was then followed by polymerase chain reaction (PCR) and viral load testing, which confirmed a new diagnosis of acute HIV infection presenting with unilateral CN VII palsy. In this report, we discuss the etiology, clinical features, differentials, and treatment options for facial nerve paralysis, along with the subtle connection to acute HIV infection.

Abstract
PURPOSE To analyze long-term outcomes in a large cohort of patients with acute peripheral facial palsy (APFP). METHODS Hospital-based, cross-sectional study. Data were abstracted from the electronic medical record. Time to recovery was assessed with Kaplan-Meier survival analyses. Binary logistic regression analysis was used to identify factors associated with outcome. RESULTS Three hundred seventy-two patients with APFP seen at a tertiary hospital between February 2015 and March 2021 were analyzed. Seasonal variation of APFP peaked in the early fall (September 29) and had a peak-to-low ratio of 1.36 (R2 = 0.329, p < 0.001). Patients who tested positive for Lyme disease (10%) had an earlier peak (July 16) compared with those who were negative (October 15). Eighty-seven percent of patients had complete recovery (averaging 64 ± 61 days). Patients, with higher House-Brackmann (H-B) grades at presentation took longer to recover, were more likely to have aberrant regeneration and had lower final rates of recovery compared with those with lower H-B grades (χ2 = 12.03, p < 0.001). Of the patients with residual palsies, 70% had evidence of aberrant regeneration, and nearly half of those had hemifacial spasm. CONCLUSIONS Most patients with APFP achieve complete recovery within 1 year, including those positive for Lyme. More severe palsy at presentation portends a worse outcome.

Abstract
INTRODUCTION Concerns were raised over an increase in Bell's palsy, herpes simplex and herpes zoster after BNT162b2 vaccination, all are manifestations of herpesviruses reactivation. As herpesviruses commonly reactivate in the oropharynx, we have hypothesized that oropharyngeal shedding of herpesviruses will increase after vaccination. METHODS Immune-competent Adults, excluding those using topical steroids or manifesting symptomatic herpesvirus infection, were sampled before BNT162b2 vaccination and one week after. Herpesviruses 1-7 shedding was tested with a multiplexed PCR. RESULTS In 103 paired samples the prevalence of herpesviruses was similar before and after vaccination: HSV1, 3.9% vs. 5.8% (p = 0.75); HSV2, 0% vs. 1% (p = not applicable, NA); VZV, 0% vs. 0% (p = NA); EBV, 14.6% vs. 17.5% (p = 0.63); CMV, 0% vs. 0% (p = NA); HHV6, 4.9% vs. 7.8% (p = 0.55); HHV7, 71.8% vs. 72.8% (p = 1); any herpesvirus, 73.8% vs. 74.8% (p = 1). DISCUSSION We did not find evidence for increased oropharyngeal reactivation of herpesviruses one week after BNT162b2.

Abstract
Previous studies have shown controversial results on the risk of Bell’s palsy after influenza vaccination. Since the antigenic components of influenza vaccine can vary from season to season, continuous safety monitoring is required. The aim of the present study was to determine whether there was an increased risk of Bell’s palsy in the elderly after influenza vaccination between the 2015/2016 and 2017/2018 flu seasons. This study included the elderly who received influenza vaccinations for three flu seasons using a large-linked database of vaccination registration data from the Korea Disease Control and Prevention Agency and the National Health Insurance Service claims data. We used a self-controlled risk interval design with a risk interval of 1 to 42 days and a control interval of 57 to 98 days postvaccination and calculated the incidence rate ratio. To ensure the robustness of the results, sensitivity analyses were also carried out with different risk and control intervals. Of 4,653,440 elderly people who received the influenza vaccine, there was no statistically significant increase in the risk of Bell’s palsy (IRR: 0.99, 95% CI: 0.92–1.07). Similar results were found in analysis results for each season and the results of the sensitivity analyses excluding the 2017/2018 season. In conclusion, we found no evidence of an increased risk of Bell’s palsy after influenza vaccination. The results of our study provide reassurance about the safety of the influenza vaccine NIP program. However, it is necessary to continuously monitor the risk of Bell’s palsy during future flu seasons.

Abstract
BACKGROUND Facial palsy is a rare, unexpected complication of temporal lobectomy (TL) for intractable epilepsy. Even without direct manipulation, the facial nerve fibers may be at risk of injury during supratentorial surgery, including TL. OBSERVATIONS The authors presented two cases of facial palsy after unremarkable TL. In the first case, the palsy appeared in a delayed fashion and completely resolved within weeks. In the second case, facial nerve dysfunction was observed immediately after surgery, followed by progressive recovery over 2 years. The second patient had a dehiscence of the roof of the petrous bone overlying the geniculate ganglion, which put the facial nerve at risk of bipolar coagulation thermal injury. LESSONS Two major mechanisms could explain the loss of facial nerve function after TL: surgery-related indirect inflammation of the nerve resulting in herpesvirus reactivation and delayed dysfunction (Bell's palsy) or indirect thermal damage to the geniculate ganglion through a dehiscent petrous roof.

Abstract
PURPOSE To examine the etiology, clinical course, and management of recurrent peripheral facial nerve paralysis. METHODS Retrospective review at a single tertiary academic center and systematic review of the literature. Clinical presentation, laboratory and imaging findings, treatment and outcome for all cases of recurrent ipsilateral, recurrent contralateral, and bilateral simultaneous cases of facial paralysis are reviewed. RESULTS Between 2000 and 2017, 53 patients [41.5% men, 29 median age of onset (range 2.5 wk-75 yr)] were evaluated for recurrent facial nerve paralysis at the authors' institution. Twenty-two (41.5%) cases presented with ipsilateral recurrences only, while the remaining 31 patients (58.5%) had at least 1 episode of contralateral recurrent paralysis. No cases of bilateral simultaneous facial nerve paralysis were observed. The median number of paretic events for all patients was 3 (range 2-20). The median nadir House-Brackmann score was 4, with a median recovery to House-Brackmann grade 1.5 over a mean recovery time of 61.8 days (range 1-420 d). Diagnostic evaluation confirmed Melkersson-Rosenthal syndrome in four (7.5%) cases, neurosarcoidosis in two (3.7%), traumatic neuroma in one (1.9%), Ramsay Hunt syndrome in one (1.9%), granulomatosis with polyangiitis in one (1.9%), and neoplastic causes in three (5.7%) cases [facial nerve schwannoma (n = 2; 3.7%), metastatic squamous cell carcinoma to the deep lobe of the parotid gland (n = 1; 1.9%)]; ultimately, 77.4% (41) of cases were deemed idiopathic. Facial nerve decompression via a middle cranial fossa approach was performed in three (5.7%) cases without subsequent episodes of paralysis. CONCLUSION Recurrent facial nerve paralysis is uncommon and few studies have evaluated this unique population. Recurrent ipsilateral and contralateral episodes are most commonly attributed to idiopathic facial nerve paralysis (i.e., Bell's palsy); however, a subset harbor neoplastic causes or local manifestations of underlying systemic disease. A comprehensive diagnostic evaluation is warranted in patients presenting with recurrent facial nerve paralysis and therapeutic considerations including facial nerve decompression can be considered in select cases.

Abstract
OBJECTIVE To evaluate the risk of cardio-cerebrovascular disease (CCVD), such as ischemic stroke and acute myocardial infarction (AMI), in patients diagnosed with Bell palsy STUDY DESIGN: Population-based follow-up study. METHODS We used the National Sample Cohort 2002 to 2013 data from the Korea National Health Insurance Service. The Bell palsy group comprised all patients diagnosed with Bell palsy (n = 730). The comparison group comprised patients selected randomly using propensity score matching (n = 1,460). The Kaplan-Meier survival analysis, log-rank test, and Cox proportional-hazards regression models were used to calculate the disease-free survival rate and hazard ratio (HR) of CCVD for each group. RESULTS Of the total study population, ischemic stroke developed in 15.7% of patients with Bell palsy and 9% of patients in the comparison group during the 12-year follow-up period. After adjusting for other factors, the HR of ischemic stroke during the 12-year follow-up period was 1.84 times greater in the Bell palsy group than in the comparison group (95% confidence interval [CI], 1.43-2.36). However, the adjusted HR of developing ischemic stroke for patients with Bell palsy treated concurrently with antiviral agents and steroids was 1.12 (95% CI, 0.62.-2.04). There was no significant relationship between Bell palsy and risk of AMI development (HR, 1.13; 95% CI, 0.71-1.82). CONCLUSION Bell palsy is linked with an increased incidence of ischemic stroke. Our data suggest that Bell palsy may be used as an indicator of increased stroke risk, and concurrent treatment with antiviral agents and steroids may be effective in preventing ischemic stroke. LEVEL OF EVIDENCE NA Laryngoscope, 129:2371-2377, 2019.

Abstract
Patients afflicted with facial paralysis suffer significant physical and psychosocial effects that can lead to depression and social isolation. Timely diagnosis and initiation of appropriate therapy are keys to achieving good outcomes in the management of facial paralysis. Eye protection is of paramount importance to prevent vision loss in patients with impaired eye closure. Patients should be assessed for signs of depression and treated appropriately.

Abstract
Objective Bell's palsy is a cranial nerve VII dysfunction that renders the patient unable to control facial muscles from the affected side. Nevertheless, some patients have reported cutaneous changes in the paretic area. Therefore, cutaneous sensibility changes might be possible additional symptoms within the clinical presentation of this disorder. Accordingly, the aim of this research was to investigate the relationship between cutaneous sensibility and facial paralysis severity in these patients. Study Design Prospective longitudinal cohort study. Settings Tertiary care medical center. Subjects and Methods Twelve acute-onset Bell's palsy patients were enrolled from March to September 2009. In addition, 12 sex- and age-matched healthy volunteers were tested. Cutaneous sensibility was evaluated with pressure threshold and 2-point discrimination at 6 areas of the face. Facial paralysis severity was evaluated with the House-Brackmann scale. Results Statistically significant correlations based on the Spearman's test were found between facial paralysis severity and cutaneous sensitivity on forehead, eyelid, cheek, nose, and lip ( P < .05). Additionally, significant differences based on the Student's t test were observed between both sides of the face in 2-point discrimination on eyelid, cheek, and lip ( P < .05) in Bell's palsy patients but not in healthy subjects. Conclusion Such results suggest a possible relationship between the loss of motor control of the face and changes in facial sensory information processing. Such findings are worth further research about the neurophysiologic changes associated with the cutaneous sensibility disturbances of these patients.

Abstract
CONCLUSION oVEMP could be a useful tool for predicting the prognosis of Bell's palsy comparable to ENoG and H-B grade. OBJECTIVES Several previous studies have reported cases of Bell's palsy with vestibular function disorder. The basic hypothesis behind this effect lies in the close proximity of the vestibular and facial nerves in the internal auditory canal (IAC). Therefore, the aim of this study was to investigate the correlation between Bell's palsy prognosis and ocular vestibular evoked myogenic potentials (oVEMPs). METHODS Total 104 consecutive patients who were diagnosed with Bell?s palsy from January 2012 to December 2014 were enrolled. Patients were divided into complete recovery group and incomplete recovery group. All of patients underwent oVEMP recordings within 1 week after disease onset. For the evaluation of correlation between H-B grades, ENoG, oVEMP and Recovery of Bell?s palsy, logistic regression analysis was performed. RESULTS The mean value of ocular vemp asymmetry was significantly higher in the incomplete recovery group than the complete recovery group (p < 0.05). No association was found between the ipsilesional PTA threshold, caloric test, and rate of abnormal EMG and recovery state. However, the initial state of ENoG, initial H-B grade, and oVEMP abnormal findings (Latency & Amplitude symmetry ratio) were significantly correlated with the rate of recovery (p = 0.025, p = 0.013, and p < 0.005, respectively).

Abstract
Acupuncture has emerged as an alternative therapy for Bell’s palsy in both adults and children. However, the use of acupuncture is controversial. We conducted a systematic review and meta-analysis to assess the efficacy of acupuncture for Bell’s palsy. We searched PubMed, Embase, and the Cochrane Central Register of Controlled Trials, irrespective of any language restrictions. Randomized controlled trials comparing acupuncture with other therapies for Bell’s palsy in adults or children were included. Fourteen randomized controlled trials involving 1541 individuals were included in this meta-analysis. Significant association was observed in acupuncture with a higher effective response rate for Bell’s palsy (relative risk, 1.14; 95% confidence interval, 1.04–1.25; P = 0.005) but there was a heterogeneity among the studies (I2 = 87%). An assessment of the included studies revealed a high risk of bias in methodological quality. An evaluation of the incidence of complications was not available, owing to incomplete data. Acupuncture seems to be an effective therapy for Bell’s palsy, but there was insufficient evidence to support the efficacy and safety of acupuncture. However, the results should be interpreted cautiously, because of the poor quality and heterogeneity of the included studies.

Abstract
BACKGROUND To investigate the relationship with prognosis, various neurotological examinations evaluating all four nerves within the internal auditory canal were performed in patients with Bell's palsy. METHODS A total of 69 consecutive patients with Bell's palsy were included. They were treated uniformly with steroid and an antiviral agent and underwent neurotological examinations consisting of electronystagmography, pure-tone audiometry (PTA), electroneurography (ENoG), caloric test, rotatory chair test and cervical vestibular evoked myogenic potentials (cVEMP). According to the final recovery state, patients were divided into two groups: a complete recovery group and an incomplete recovery group. The incidence of abnormal findings in each test was compared between the two groups. RESULTS Fifty-six patients recovered completely and 13 patients recovered incompletely. No association was observed between the rate of ipsilesional PTA threshold and the rate of abnormal caloric test, function tests and recovery state. However, the initial state of facial palsy, ENoG and the rate of abnormal cVEMP were significantly correlated with the rate of recovery. CONCLUSION The results indicate that Bell's palsy may be more comparable to mononeuritis multiplex and that cVEMP could be a useful tool for predicting the prognosis of Bell's palsy.

Abstract
It has been documented that infection of herpes simplex virus type 1 (HSV-1) contributes to the initiation of Bell's palsy. However, the exact mechanisms responsible for this disorder have not been fully elucidated to date. A mouse model of facial palsy induced by HSV-1 provides an opportunity to investigate the alteration in activities of nuclear factor-kappa B (NF-κB) and its consequent effect on two key inflammatory factors, i.e., tumor necrosis factor (TNF)-α and cyclooxygenase-2 (COX-2), as well as the effect of glucocorticoids (GCs) in this work. I-kappa B (IκB)-α phosphorylation and NF-κB nuclear translocation were measured by western blotting, and NF-κB/DNA binding activity was assessed by electrophoretic mobility shift assay (EMSA). Results showed the IκB-α phosphorylation and degradation as well as NF-κB activation in a time-dependent manner. The expression of TNF-α and COX-2 were determined by real-time polymerase chain reaction (PCR), western blotting and/or enzyme-linked immunosorbent assay (ELISA) respectively. Concomitant with the activation, the expression and secretion of TNF-α and COX-2 were rapidly induced in HSV-1-infected paralyzed mice. Conversely, the activation of NF-κB and up-regulation of TNF-α and COX-2 were blocked by pretreatment with NF-κB inhibitor pyrrolidine dithiocarbamate (PDTC) before being inoculated with HSV-1 to mice. In addition, GCs inhibited the nuclear translocation and DNA binding activity of NF-κB via inhibiting IκB-α degradation. Meanwhile, TNF-α production and COX-2 expression were significantly reduced by GCs. In conclusion, HSV-1 inoculation induced the activation of NF-κB, expression and secretion of TNF-α and COX-2 in the facial paralyzed mice, while, glucocorticoid effectively down-regulated TNF-α and COX-2 expression in HSV-1-induced paralyzed mice.

Abstract
Spontaneous idiopathic facial nerve (Bell's) palsy leaves residual hemifacial weakness in 29% which is severe and disfiguring in over half of these cases. Acute medical management remains the best way to improve outcomes. Reconstructive surgery can improve long term disfigurement. However, acute and surgical options are time-dependent. As family practitioners see, on average, one case every 2 years, a summary of this condition based on common clinical questions may improve acute management and guide referral for those who need specialist input. We formulated a series of clinical questions likely to be of use to family practitioners on encountering this condition and sought evidence from the literature to answer them. The lifetime risk is 1 in 60, and is more common in pregnancy and diabetes mellitus. Patients often present with facial pain or paraesthesia, altered taste and intolerance to loud noise in addition to facial droop. It is probably caused by ischaemic compression of the facial nerve within the meatal segment of the facial canal probably as a result of viral inflammation. When given early, high dose corticosteroids can improve outcomes. Neither antiviral therapy nor other adjuvant therapies are supported by evidence. As the facial muscles remain viable re-innervation targets for up to 2 years, late referrals require more complex reconstructions. Early recognition, steroid therapy and early referral for facial reanimation (when the diagnosis is secure) are important features of good management when encountering these complex cases.

Abstract
Acupuncture is a common and effective therapeutic method to treat facial nerve palsy (FNP). However, its underlying mechanism remains unclear. This study was aimed to investigate the effects of electroacupuncture on symptoms and content of HSV-1 DNA in FNP mice. Mice were randomized into four groups, an electroacupuncture treatment group, saline group, model animal group, and blank control group. Electroacupuncture was applied at Jiache (ST6) and Hegu (LI4) in electroacupuncture group once daily for 14 days, while electroacupuncture was not applied in model animal group. In electroacupuncture group, mice recovered more rapidly and HSV-1 DNA content also decreased more rapidly, compared with model animal group. We conclude that electroacupuncture is effective to alleviate symptoms and promote the reduction of HSV-1 in FNP.

Abstract
Background Recent advances in Bell’s palsy (BP) were reviewed to assess the current trends in its management and prognosis. Material/Methods We retrieved the literature on BP using the Cochrane Database of Systematic Reviews, PubMed, and Google Scholar. Key words and phrases used during the search included ‘Bell’s palsy’, ‘Bell’s phenomenon’, ‘facial palsy’, and ‘idiopathic facial paralysis’. Emphasis was placed on articles and randomized controlled trails (RCTs) published within the last 5 years. Results BP is currently considered the leading disorder affecting the facial nerve. The literature is replete with theories of its etiology, but the reactivation of herpes simplex virus isoform 1 (HSV-1) and/or herpes zoster virus (HZV) from the geniculate ganglia is now the most strongly suspected cause. Despite the advancements in neuroimaging techniques, the diagnosis of BP remains one of exclusion. In addition, most patients with BP recover spontaneously within 3 weeks. Conclusions Corticosteroids are currently the drug of choice when medical therapy is needed. Antivirals, in contrast, are not superior to placebo according to most reliable studies. At the time of publication, there is no consensus as to the benefit of acupuncture or surgical decompression of the facial nerve. Long-term therapeutic agents and adjuvant medications for BP are necessary due to recurrence and intractable cases. In the future, large RCTs will be required to determine whether BP is associated with an increased risk of stroke.

Abstract
OBJECTIVE The purpose of this case study is to describe the effect of chiropractic care on a patient with chronic Bell's palsy. CLINICAL FEATURES A 47-year-old woman with medically diagnosed Bell's palsy presented for chiropractic care. She had experienced right sinus pressure and congestion, lack of facial tone on the right, and intermittent tingling of the right side of her face. INTERVENTIONS AND OUTCOMES The patient received high-velocity, low-amplitude chiropractic manipulation (adjustments) to the cervical and thoracic spine, interferential muscle stimulation, and hydroculation on the trapezius muscles bilaterally. Reduction in symptoms occurred following the initial visit and continued over the next 9 weeks of care. After the course of a year of chiropractic care, the patient reached 90% improvement. CONCLUSIONS For this patient, chiropractic care reduced Bell's palsy symptoms.

Abstract
Facial nerve palsy, as a complication of an inferior alveolar nerve block anesthesia, is a rarely reported incident. Based on the time elapsed, from the moment of the injection to the onset of the symptoms, the paralysis could be either immediate or delayed. The purpose of this article is to report a case of delayed facial palsy as a result of inferior alveolar nerve block, which occurred 24 hours after the anesthetic administration and subsided in about 8 weeks. The pathogenesis, treatment, and results of an 8-week follow-up for a 20-year-old patient referred to a private maxillofacial clinic are presented and discussed. The patient's previous medical history was unremarkable. On clinical examination the patient exhibited generalized weakness of the left side of her face with a flat and expressionless appearance, and she was unable to close her left eye. One day before the onset of the symptoms, the patient had visited her dentist for a routine restorative procedure on the lower left first molar and an inferior alveolar block anesthesia was administered. The patient's medical history, clinical appearance, and complete examinations led to the diagnosis of delayed facial nerve palsy. Although neurologic occurrences are rare, dentists should keep in mind that certain dental procedures, such as inferior alveolar block anesthesia, could initiate facial nerve palsy. Attention should be paid during the administration of the anesthetic solution.

In clinical medicine there may be times when clinical conditions manifest differently both when they present individually or concomitantly. Such scenarios warrant a broader differential diagnosis with thorough investigations. We present one such case of a patient of Bell's palsy with unexplained eye pain on the ipsilateral side. The patient had a chronic retinal detachment which became worse due to the concomitant Bell's palsy.

Abstract
INTRODUCTION Detection of intrathecal synthesis of specific antibodies (antibody index (AI)) is an established method to prove cerebral viral infection. Experience on its clinical application in large patient groups, however, is sparse. METHODS Retrospective analysis of pediatric patients with positive viral AI treated at RWTH Aachen University Hospital between 1999 and 2005. RESULTS 63 patients were studied, including 14 with encephalitis, 12 with neuritis, nine with cerebral vasculitis, six with multiple sclerosis (MS), five with severe cephalgia, five with psychiatric symptoms, three with hearing loss, two with seizures, three with white matter diseases, two with movement disorders, one with meningococcal meningitis and one with sinus venous thrombosis. Seven had several positive AI among them only one patient with MS. Of the 51 patients with a single positive AI and not having MS, 16 showed a positive AI for herpes simplex-, 13 for varicella zoster-, nine for Epstein-Barr-, four for cytomegalo-, four for mumps-, three for rubella- and two for measles virus. Frequent combinations were varicella zoster virus (VZV) and vasculitis (n = 8), herpes simplex virus (HSV) and neuritis (n = 6), Epstein-Barr virus (EBV) (n = 5), respectively, VZV (n = 4) and encephalitis as wells as mumps virus (n = 2) and hearing loss. Matched polymerase chain reaction (PCR) and AI data were available in 25 patients. PCR was simultaneously positive in three cases only. DISCUSSION AI testing identifies a similar spectrum of pathogens as known from cerebrospinal fluid (CSF) PCR studies. It complements the PCR and increases the chance for adequate diagnosis and treatment of patients with assumed cerebral viral infections.

Estes vírus possuem características biológicas particulares, tais como a capacidade de causar diferentes tipos de doenças, assim como estabelecer infecções latentes ou persistentes por toda a vida dos hospedeiros e de serem reativados causando lesões que podem se localizar no sítio da infecção primária inicial ou próxima a ele. Postula-se que a reativação deste vírus no gânglio geniculado esteja relacionada com a paralisia de Bell. Nesta situação, os vírus, que estariam latentes neste gânglio, sofreriam reativação e replicação difundindo-se pelo nervo facial e seus ramos, dentre eles o nervo corda do tímpano, que ao estimular a secreção salivar possibilitaria a identificação do DNA viral na saliva dos pacientes. Até recentemente, um grande número de pacientes eram diagnosticados como portadores de uma forma desta paralisia, chamada de idiopática ou de paralisia de Bell. Com o advento da técnica de estudo do DNA viral pelo método da reação da polimerase em cadeia (PCR), diversos autores encontraram DNA do vírus herpes simplex tipo I no líquido cefalorraquidiano, na secreção lacrimal, na saliva e nos gânglios geniculados de pacientes com paralisia de Bell. OBJETIVO: observar a prevalência do vírus herpes simplex tipo I pela técnica de PCR, na saliva de pacientes com PFP de Bell, relacionando-a com a evolução clínica destes casos. METODOLOGIA: Avaliamos 38 pacientes portadores de Paralisia Facial Periférica de Bell, que foram submetidos a anamnese, exame médico geral e otorrinolaringológico e coleta de saliva para detecção do DNA viral pela técnica de PCR. O grupo controle correspondeu a 10 adultos normais. RESULTADOS: Obtivemos positividade para o DNA viral em 11 casos dos 38 avaliados, o que corresponde a 29% da amostra. Este resultado foi estatisticamente significante se comparado ao grupo controle, no qual não foi obtido nenhum caso de positividade. CONCLUSÃO: Concluiu-se que a presença do HSV-1 na saliva de pacientes portadores de PFP de Bell indica que a reativação viral pode ser a etiologia desta doença. A detecção do vírus na saliva destes pacientes não influencia o prognóstico da doença.

Abstract
The first herpes virus to be described was types 1 and 2, whose denomination is herpes simplex 1 and 2 or HSV -1 and HSV -2. These viruses have specific biological characteristics, such as the ability to cause different kinds of diseases, as well as to establish host's latent or persistent lifetime infections and also of being reactivated, causing lesions that can be located at the same site of the initial primary infection or close to it. It is suggested that this virus reactivation in the geniculate ganglion may be related to Bell's palsy. In this situation, the viruses that would be latent in this ganglion, would suffer reactivation and replication, then be diffused through the facial nerve and its branches, among them the chorda tympani nerve, which by stimulating salivary secretion would enable the identification of the viral DNA in the patients’ saliva. Until recently, a great number of patients was diagnosed as holders of this kind of paralysis, named idiopathic or Bell's palsy. With the introduction of the technique studying the viral DNA by Polymerase Chain Reaction (PCR), several authors have found herpes simplex virus type I DNA in the cerebrospinal fluid, in the lachrymal secretion, in the saliva and in the geniculate ganglia of patients with Bell's palsy. Aim observe the occurrence of herpes simplex type I virus using PCR technique in the saliva of patients with Bell's palsy and relating it to the clinical evolution of these cases. Methodology We evaluated 38 patients with Bell's palsy submitted to anamnesis, clinical and ENT examination and saliva sampling for viral DNA detection by PCR technique. The control group was ten normal adults. Results We found positive viral DNA in 11 cases out of the 38, which corresponded to 29% of the sample. This result was statistically significant if compared to the control group, in which we did not find any positive case. Conclusion The end result was that the presence of HSV -1 in the saliva of patients with Bell's palsy indicating that the viral reactivation can be the etiology of this disease. The detection of the virus in these patients’ saliva does not influence the disease prognosis.

Abstract
OBJECTIVE To induce experimental peripheral facial paralysis by inoculation of HSV1 and to compare the effects of steroid, acyclovir, lipoprostoglandin E2 and steroid + acyclovir treatments in terms of clinical recovery, electrophysiologically and histopathologically. MATERIALS AND METHODS A total of 132 adult female rats were used in this study. HSV type 1 strain was inoculated at the back of the left ear by using 27 gauge needle. Of all animals, 70 (53%) rats which developed facial paralysis were divided into five groups (n = 14 for each group) as control, steroid + acyclovir, lipoprostaglandin E1, steroid only and acyclovir only. At the end of the 21 days period, the rats were clinically examined and electrophysiological tests were performed, then decapitated and the nerve specimens were obtained. RESULTS A modified electroneurography (ENoG) test was performed and the latencies and the amplitudes were compared. The findings of the intact side were better, but with no significant difference. Histopathologicaly edema was significantly smaller in all groups compared to the controls (p < 0.05). Similarly, no difference was seen in terms of vacuolar degeneration and Schwann cell hyperchromatisation among the groups and no significant difference in recovery period and rate of facial paralysis when all groups were compared. CONCLUSION Facial paralysis induced by HSV1 recovered spontaneously within a week. In the treatment of facial paralysis, steroid alone, acyclovir alone, steroid + acyclovir, or lipoprostaglandin E1 all reduced edema in the infected facial nerve but there was no statistical difference in of the rate or degree of recovery.

Abstract
BACKGROUND Reactivation of herpes simplex virus type 1 is thought to be a major cause of adult idiopathic peripheral facial paralysis or Bell's palsy. However, few studies have examined the pathogenesis of this condition in children. Serologic assays and polymerase chain reaction (PCR) analysis of paired sera and saliva samples were used here to investigate the causes of acute peripheral facial paralysis in pediatric patients. METHODS A total of 30 children with acute peripheral facial paralysis were recruited. Paired sera were assayed for evidence of herpesvirus, mumps virus or Borrelia infection. PCR was used to detect herpes simplex virus type 1 and varicella-zoster virus (VZV) DNA in saliva samples. RESULTS Ramsay Hunt syndrome with accompanying zoster lesions was diagnosed clinically in 2 patients, and VZV reactivation was confirmed serologically. VZV reactivation in the absence of zoster (zoster sine herpete) was diagnosed in 9 patients with either serologic assays or PCR. Thus VZV reactivation was demonstrated in 11 of 30 (37%) patients. The prevalence of VZV reactivation among patients between 6 and 15 years of age was significantly higher than in those younger than 5 years of age (53% versus 9%, P = 0.023). CONCLUSIONS Our data indicate that VZV reactivation is an important cause of acute peripheral facial paralysis in children, especially those between 6 and 15 years of age.

Abstract
OBJECTIVES Bell's palsy has recently been claimed to be caused by herpes simplex virus type 1 (HSV-1) infection. The anti-viral agent acyclovir is a specific inhibitor of herpesvirus replication, and the most effective agent for the treatment herpesvirus infection. The purpose of this experiment was to assess the effect of acyclovir on the facial nerve paralysis included by HSV-1 infection. METHODS We succeeded in producing an animal model of acute and transient facial nerve paralysis induced with HSV-1 neuritis simulating human Bell's palsy. In this study, acyclovir administration was performed before and after facial nerve paralysis, and continued for 5 days. Controls were given phosphate-buffer saline (PBS) instead of acyclovir, and the incidence and duration of facial nerve paralysis was compared in the acyclovir groups and controls. RESULTS The incidence of facial nerve paralysis was significantly lower in the group given acyclovir before the paralysis than in the controls, and the duration of facial nerve paralysis was shorter. CONCLUSIONS Administration of acyclovir before the paralysis reduced the incidence and duration of facial nerve paralysis. Administration of acyclovir after the paralysis improved the duration of facial nerve paralysis.

Abstract
Herpes simplex virus type 1 (HSV-1) has been proven to be a cause of Bell's palsy; however, the underlying pathophysiology of the facial nerve paralysis is not fully understood. We established a mouse model with facial nerve paralysis induced by HSV-1 infection simulating Bell's palsy and investigated the pathophysiology of the facial nerve paralysis. The time course of the R1 latency in the blink reflex tests paralleled the recovery of the facial nerve paralysis well, whereas electroneurographic recovery tended to be delayed, compared to that of the paralysis; these responses are usually seen in Bell's palsy. On histopathologic analysis, intact, demyelinated, and degenerated nerves were intermingled in the facial nerve in the model. The similarity of the time course of facial nerve paralysis and the electrophysiological results in Bell's palsy and the model strongly suggest that the pathophysiological basis of Bell's palsy is a mixed lesion of various nerve injuries.

Abstract
OBJECTIVE To evaluate the use of electroneurography (ENOG) as a prognostic indicator in Bell's Palsy for Chinese patients in Hong Kong. STUDY DESIGN Prospective study. SETTING Tertiary referral outpatient center. PATIENTS Sixty-three consecutive patients with a diagnosis of Bell's Palsy in Tuen Mun Hospital, Hong Kong, from January 1995 to January 1998. INTERVENTIONS ENOG, protective eye care, and exercise of the facial muscles. MAIN OUTCOME MEASURES ENOG was performed 5 to 14 days after the onset of facial palsy. The recovery of facial nerve function was documented by House and Brackmann grading. All the patients were followed up monthly until recovery or up to 6 months. RESULTS Sixty-three patients were randomly divided into two groups of 32 and 31 patients. The first part of the study was to analyze the correlation between ENOG values and the chance of recovery in Group 1 patients (n = 32) by means of a logistic regression model. The result showed that patients with ENOG values less than 72.63% had a greater than 90% chance of recovery to House Grade II or better within 2 months (Wald = 6.19, p < 0.05). The second part of the study was to assess the capability of this ENOG value to accurately predict the prognosis of Bell's Palsy in Group 2 patients (n = 31) using Fisher's exact test (p < 0.0001). The sensitivity and specificity of ENOG in predicting a good prognosis (recovery to House Grade III or better after 2 months) in patients with Bell's Palsy were 82% and 100%, respectively. CONCLUSION The ENOG value as a useful prognostic indicator in Chinese patients with Bell's Palsy in Hong Kong was confirmed.

Abstract
Vagus nerve palsy caused by herpes simplex virus (HSV) infection is rare. Here, we present a 29-year-old man with acute onset of right side otalgia and sore throat, followed by dysphonia, dysphagia and some vesicles seen on the deep soft palate. Laryngoscopy revealed right vocal cord palsy. Neck to chest CT did not reveal local lesion. Three months later, his serum HSV IgG antibody titer was eight times elevation and a throat swab culture for virus isolation yielded HSV type I. T2-weighted images of neck MRI showed abnormally high signal intensity on the right sub-glottis region with Gadolinium enhancement that was compatible with local infection. Thereafter, one course of acyclovir; was given. Three months after finishing the acyclovir, his symptoms were almost gone and neck MRI did not show the aforementioned lesions. HSV infection should be considered as a differential diagnosis for patients with idiopathic dysphonia and dysphagia.

Abstract
An acute polyneuropathy developing over days to several weeks is most likely to be Guillain-Barré syndrome or a toxic neuropathy, although vasculitis can also present acutely. This presentation should be referred immediately for further investigation. A subacute to chronic (ie, developing over months) neuropathy with significant proximal weakness and prominent loss of reflexes is highly suggestive of chronic inflammatory demyelinating polyradiculoneuropathy. If there is a clear stepwise onset of symptoms, suggestive of multiple mononeuropathies, or significant asymmetry, vasculitic neuropathy should be considered, even in the absence of systemic vasculitis. Idiopathic chronic axonal neuropathy is an indolent, predominantly sensory neuropathy that typically occurs in older patients. Neuropathies occurring in young or middle age or with more subacute onset always warrant further investigation.

Abstract
Electrodiagnostic testing (electromyography, electroneuronography, and blink reflex) and cerebrospinal fluid (CSF) examination (cell count, immunoglobulins, and antigen-specific intrathecal immunoglobulin G synthesis against herpes simplex virus, varicella zoster virus, cytomegalovirus, and Borrelia burgdorferi sensu latu) were performed in 56 patients with Bell's palsy. The CSF was normal in 45 patients and abnormal in 11 patients. Acute borreliosis was the most common specific pathological CSF finding (4 of 11). Electromyography revealed abolished volitional activity in 22% of patients with normal CSF and in 36% with pathological CSF. Electroneuronographic tests with an amplitude decrease of more than 90% on the affected side or abolished responses were found in 20% of patients with normal CSF and in 18% with pathological CSF. Abolished orbicularis oculi reflexes were seen in 67% of patients with normal CSF and in 82% with pathological CSF Concerning electrodiagnostic testing, no statistically significant difference between patients with normal and abnormal CSF was found, so we conclude that electrodiagnostic testing has no indicative value for abnormal CSF in Bell's palsy.

Abstract
Normal facial movement is required for chewing, swallowing, speaking, and protecting the eye. Bell's palsy causes most cases of acute, unilateral facial palsy; infection with herpes simplex virus (HSV) type 1 may be its major cause. Varicella zoster virus (VZV) reactivation (Ramsay Hunt syndrome) is less common, but may appear without skin lesions in a form indistinguishable from Bell's palsy. Symptoms improve in nearly all patients with Bell's palsy, and most patients with Ramsay Hunt syndrome, but many are left with functional and cosmetic deficits. Steroids are frequently used to optimize outcomes in Bell's palsy, but proof of their effectiveness is marginal. Oral prednisone has been studied extensively, although some reports have suggested a higher recovery rate with intravenous steroids. Given the existing data, we support the use of oral prednisone in those patients with complete facial palsy, and no contraindications to their use (Fig. 1). In this author's opinion, the greatly increased cost and inconvenience of intravenous steroids cannot be justified by the data available. Antiviral agents may also be effective in treatment of Bell's palsy; HSV is susceptible to acyclovir and related agents. There have been few investigations of acyclovir treatment in Bell's palsy, but one controlled study showed added benefit when the drug was used with prednisone. The risk and cost of acyclovir is low enough that we support its use, with oral steroids, in those patients with complete facial paralysis. Several small studies have implied that oral acyclovir improves the outcome of facial palsy for patients with Ramsay Hunt syndrome. Although these studies do not prove efficacy, evidence for the benefits of antiviral agents in other forms of zoster is strong enough to recommend their use when the facial nerve is involved. VZV is less sensitive to acyclovir than HSV, so higher doses are recommended to treat Ramsay Hunt syndrome. Because some Ramsay Hunt syndrome patients with partial facial palsy do not fully recover, we recommend oral antiviral agents in all patients suspected of having zoster. There is weak evidence to suggest additional benefit of oral steroids in facial zoster, and their use can be supported in immunocompetent individuals. Facial nerve decompression surgery for Bell's palsy and herpes zoster oticus has experienced varying levels of enthusiasm over the years. Recent work implies that early, extensive decompression of the nerve through a middle fossa craniotomy may benefit patients at high risk for persistent deficits. However, until this procedure is subjected to a rigorous, controlled trial comparing it with maximal medical therapy, it is difficult to justify the very high costs and risk.

Abstract
Varicella-zoster virus (VZV) and herpes simplex virus (HSV) are considered to be the major causes of acute peripheral facial palsy (APFP). One hundred and forty-two patients with APFP were analyzed by serological assays and polymerase chain reaction analysis. Ramsay Hunt syndrome was diagnosed in 21 patients. Of the remaining 121 patients clinically diagnosed with Bell's palsy, VZV reactivation without zoster (zoster sine herpete) was detected in 35 patients (29%). The prevalence of antibodies to HSV among patients with Bell's palsy was significantly higher than the prevalence among those with VZV reactivation (Ramsay Hunt syndrome or zoster sine herpete). In contrast, a high incidence (88%) of VZV reactivation among HSV-seronegative patients with APFP was observed. Our data indicate that VZV is one of the major etiologic agents of clinically diagnosed Bell's palsy and that VZV reactivation causes APFP in most patients who lack antibodies to HSV.

Abstract
OBJECTIVES Incomplete return of facial motor function and synkinesis continue to be long-term sequelae in some patients with Bell's palsy. The aim of this report is to describe a prospective study in which a well-defined surgical decompression of the facial nerve was performed in a population of patients with Bell's palsy who exhibit the electrophysiologic features associated with poor outcomes. In addition, management issues related to Bell's palsy including herpes simplex virus typel etiology, the natural history, electrodiagnostic testing, and efficacy of surgical strategies are reviewed. STUDY DESIGN AND METHODS A multicenter prospective clinical trial was designed utilizing electroneurography (ENOG) and voluntary electromyography (EMG) to identify patients with Bell's palsy who would most likely develop poor return of facial function, as suggested by Fisch and Esslen. Patients who displayed electrodiagnostic features of poor outcome, >90% degeneration on ENOG testing and no voluntary motor unit EMG potentials within 14 days of onset of total paralysis, were offered a surgical decompression of the facial nerve through a middle cranial fossa surgical exposure, including the tympanic segment, geniculate ganglion, labyrinthine segment, and meatal foramen. Control subjects were those who displayed similar electrodiagnostic features and time course. RESULTS Subjects who did not reach 90% degeneration on ENOG within 14 days of paralysis all returned to House-Brackmann grade I (n = 48) or II (n = 6) at 7 months after onset of the paralysis. Control subjects self-selecting not to undergo surgical decompression when >90% degeneration on ENOG and no motor unit potentials on EMG were identified had a 58% chance of developing a poor outcome at 7 months after onset of paralysis (House-Brackmann grade III or IV [n = 19]). A group with similar ENOG and EMG findings undergoing middle fossa facial nerve decompression exhibited House-Brackmann grade I (n = 14) or II (n = 17) in 91% of the cases. An exact permutation test confirmed that the surgical group had a significantly higher proportion of patients with a good outcome (House-Brackmann grade I or II) (P = .0002). CONCLUSION Electroneurography in combination with voluntary EMG successfully identified patients who will most likely return to normal from those who had a greater chance of long-term sequelae from Bell's palsy. Surgical decompression medial to the geniculate ganglion significantly improves the chances of normal or near-normal return of facial function in the group that has a high probability of a poor result. Surgical decompression must be performed within 2 weeks of onset of total paralysis for it to be effective.

Abstract
Facial paralysis is a potentially devastating disorder with numerous implications. Multiple entities must be considered in its etiology, and recent advances in microbiology, radiographic imaging, electrodiagnostic testing, and microsurgery have provided great insight into the pathophysiology, diagnosis, treatment, and rehabilitation of the facial nerve. Recent DNA PCR testing has shed new insight into the potential cause for Bell's palsy. This article focuses on the evaluation, differential diagnosis, medical treatment, and rehabilitation of facial nerve pathology with primary emphasis on facial paralysis. Surgical management is also discussed, including reanimation of the paralyzed face.
