Task force of the Brazilian Society of Otology - evaluation and management of peripheral facial palsy. Braz J Otorhinolaryngol 2024; 90:101374. [PMID: 38377729 PMCID: PMC10884764 DOI: 10.1016/j.bjorl.2023.101374] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/13/2023] [Accepted: 11/25/2023] [Indexed: 02/22/2024] Open
Abstract
OBJECTIVE To review key evidence-based recommendations for the diagnosis and treatment of peripheral facial palsy in children and adults. METHODS Task force members were educated on knowledge synthesis methods, including electronic database search, review and selection of relevant citations, and critical appraisal of selected studies. Articles written in English or Portuguese on peripheral facial palsy were eligible for inclusion. The American College of Physicians' guideline grading system and the American Thyroid Association's guideline criteria were used for critical appraisal of evidence and recommendations for therapeutic interventions. RESULTS The topics were divided into 2 main parts: (1) Evaluation and diagnosis of facial palsy: electrophysiologic tests, idiopathic facial palsy, Ramsay Hunt syndrome, traumatic peripheral facial palsy, recurrent peripheral facial palsy, facial nerve tumors, and peripheral facial palsy in children; and (2) Rehabilitation procedures: surgical decompression of the facial nerve, facial nerve grafting, surgical treatment of long-term peripheral facial palsy, and non-surgical rehabilitation of the facial nerve. CONCLUSIONS Peripheral facial palsy is a condition of diverse etiology. Treatment should be individualized according to the cause of facial nerve dysfunction, but the literature presents better evidence-based recommendations for systemic corticosteroid therapy.

Abstract
BACKGROUND Facial palsy after orthognathic surgery is an uncommon but serious complication causing dissatisfaction and affecting quality of life. The occurrence could be underreported. Surgeons need to recognize this issue regarding the incidence, causative mechanism, managements, and outcome. METHODS A retrospective review of orthognathic surgery records between January of 1981 and May of 2022 was conducted in the authors' craniofacial center. Patients who developed facial palsy after the surgery were identified, and demographics, surgical methods, radiologic images, and photographs were collected. RESULTS A total of 20,953 sagittal split ramus osteotomies (SSROs) were performed in 10,478 patients. Twenty-seven patients developed facial palsy, resulting in an incidence of 0.13% per SSRO. In a comparison of SSRO technique, the Obwegeser-Dal Pont technique using osteotome for splitting had higher risk of facial palsy than the Hunsuck technique using the manual twist splitting ( P < 0.05). The severity of facial palsy was complete in 55.6% of patients and incomplete in 44.4%. All patients were treated conservatively, and 88.9% attained full recovery in a median duration of 3 months [interquartile range (IQR), 2.75 to 6 months] after surgery, whereas 11.1% attained partial recovery. Initial severity of facial palsy predicted the timing of recovery, with incomplete palsy patients having faster median recovery (3 months; IQR, 2 to 3 months) than the complete palsy patients (6 months; IQR, 4 to 6.25 months) ( P = 0.02). CONCLUSIONS The incidence of facial palsy after orthognathic surgery was 0.13%. Intraoperative nerve compression was the most likely causative mechanism. Conservative treatment is the mainstay of therapeutic strategy, and full functional recovery was anticipated. CLINICAL QUESTION/LEVEL OF EVIDENCE Risk, IV.

Abstract
BACKGROUND The process of determining the prognosis and subsequent facial nerve decompression has become an important factor in determining the patient's quality of life. AIM In this study, the prognosis of facial paralysis was verified in detail based on the timing of electroneurography (ENOG) and nerve conduction study (NCS). MATERIALS AND METHODS The ENOG and NCS of 368 facial palsy patients were analyzed. House-Brackmann (HB) scale after 6 months was used as an outcome. For the ENOG, nasalis muscle/levator labii superioris alaeque nasi (NL), and orbicularis oculi (OO) muscle were used and NCS performed using temporal, zygomatic, and buccal branches. RESULTS ENOG at the OO performed 4-6 d after onset was ≤10% (p = .002, 10.0-fold) and showed unfavorable results (when the standard was ≥30%). In addition, the ENOG at the NL performed 13-15 d after onset was ≤10% (p = .001, 10.5-fold) and showed unfavorable results (when the standard was ≥30%). CONCLUSIONS The results indicated that ENOG at the OO performed 4-6 d after onset and ENOG at the NL performed 13-15 d after onset had more prognostic value for the outcomes of acute peripheral facial palsy.

Abstract
PURPOSE The key element in managing postoperative facial nerve (FN) injuries is timely diagnosis and intervention as indicated. The purpose of this study was to measure and compare evoked electromyography (EEMG) and clinical assessment in terms of the recovery of the injured FN in operated temporomandibular joint ankylosis (TMJA) cases. METHODS The investigators designed a prospective cohort study in the primary operated TMJA patients. The primary predictor variable was the technique used to assess FN function, House-Brackmann Facial Nerve Grading System (HBFNGS) or EEMG. The primary outcome variable was time to FN recovery. The FN recovery was assessed in different time points (1 week, 1 month, 3 months, and 6 months). Age, gender, side (unilateral/bilateral), type of ankylosis (Sawhney's classification), and operating time were kept as covariates. Categorical variables were analyzed using Fisher's exact test. Multilevel survival analysis was performed considering the subject as cluster to perform Kaplan-Meier analysis and compute the hazards ratio using the Cox-regression method with adjustment for covariates. P <0.05 was set as statistically significant. RESULTS The study sample composed of 43 (69 sides) TMJA cases who underwent surgery developed iatrogenic FN injury in 10 cases (14 sides [9 right; 5 left]). The incidence of FN injury was 20.3% (14/69). Sawhey's type III/type IV ankylosis and the operating time for more than 2 hours showed a statistically significant (p<0.05) increase in FN injury. The mean duration to detect FN recovery by EEMG was 9 days (95% confidence interval, 5 to 12 days), but the HBFNGS took 161 days (95% confidence interval, 141 to 181 days). The chance of early detection by EEMG was 18.6 times more than the chance by the HBFNGS (Cox-hazard ratio, 18.6). CONCLUSIONS To conclude, EEMG is a noninvasive and reliable tool that detects FN recovery much earlier than the HBFNGS in the postoperative TMJA cases.

Abstract
In Bell's palsy, electrodiagnosis by electroneurography (ENoG) is widely used to predict a patient's prognosis. The therapeutic options for patients with poor prognostic results remain controversial. Here, we investigated whether early intervention with intratympanic steroid therapy (ITST) is an effective treatment for Bell's palsy patients with poor electrodiagnostic test results (≤ 10% electroneurography value). Patients in the concurrent ITST group (n = 8) received the standard systemic dose of prednisolone (410 mg total) and intratympanic dexamethasone (16.5 mg total) and those in the control group (n = 21) received systemic prednisolone at the standard dose or higher (average dose, 605 ± 27 mg). A year after onset, the recovery rate was higher in the ITST group than in the control group (88% vs 43%, P = 0.044). The average House-Brackmann grade was better in the concurrent ITST group (1.13 ± 0.13 vs 1.71 ± 0.16, P = 0.035). Concurrent ITST improves the facial nerve outcome in patients with poor electroneurography test results, regardless of whether equivalent or lower glucocorticoid doses were administered. This may be ascribed to a neuroprotective effect of ITST due to a higher dose of steroid reaching the lesion due to dexamethasone transfer in the facial nerve.

Abstract
BACKGROUND Bell's palsy is an acute unilateral facial paralysis of unknown aetiology and should only be used as a diagnosis in the absence of any other pathology. As the proposed pathophysiology is swelling and entrapment of the nerve, some surgeons suggest surgical decompression of the nerve as a possible management option; this is ideally performed as soon as possible after onset. This is an update of a review first published in 2011, and last updated in 2013. This update includes evidence from one newly identified study. OBJECTIVES To assess the effects of surgery in the early management of Bell's palsy. SEARCH METHODS On 20 March 2020, we searched the Cochrane Neuromuscular Specialised Register, CENTRAL, MEDLINE, Embase, ClinicalTrials.gov and WHO ICTRP. We handsearched selected conference abstracts for the original version of the review. SELECTION CRITERIA We included all randomised controlled trials (RCTs) or quasi-RCTs involving any surgical intervention for Bell's palsy. Trials compared surgical interventions to no treatment, later treatment (beyond three months), sham treatment, other surgical treatments or medical treatment. DATA COLLECTION AND ANALYSIS Three review authors independently assessed trials for inclusion, assessed risk of bias and extracted data. We used standard methodological procedures expected by Cochrane. The primary outcome was complete recovery of facial palsy at 12 months. Secondary outcomes were complete recovery at three and six months, synkinesis and contracture at 12 months, psychosocial outcomes at 12 months, and side effects and complications of treatment. MAIN RESULTS Two trials with 65 participants met the inclusion criteria; one was newly identified at this update. The first study randomised 25 participants into surgical or non-surgical (no treatment) groups using statistical charts. One participant declined surgery, leaving 24 evaluable participants. The second study quasi-randomised 53 participants; however, only 41 were evaluable as 12 declined the intervention they were allocated. These 41 participants were then divided into early surgery, late surgery or non-surgical (no treatment) groups using alternation. There was no mention on how alternation was decided. Neither study mentioned if there was any attempt to conceal allocation. Neither participants nor outcome assessors were blinded to the interventions in either study. There were no losses to follow-up in the first study. The second study lost three participants to follow-up, and 17 did not contribute to the assessment of secondary outcomes. Both studies were at high risk of bias. Surgeons in both studies used a retro-auricular/transmastoid approach to decompress the facial nerve. For the outcome recovery of facial palsy at 12 months, the evidence was uncertain. The first study reported no differences between the surgical and no treatment groups. The second study fully reported numerical data, but included no statistical comparisons between groups for complete recovery. There was no evidence of a difference for the early surgery versus no treatment comparison (risk ratio (RR) 0.76, 95% confidence interval (CI) 0.05 to 11.11; P = 0.84; 33 participants; very low-certainty evidence) and for the early surgery versus late surgery comparison (RR 0.47, 95% CI 0.03 to 6.60; P = 0.58; 26 participants; very low-certainty evidence). We considered the effects of surgery on facial nerve function at 12 months very uncertain (2 RCTs, 65 participants; very low-certainty evidence). Furthermore, the second study reported adverse effects with a statistically significant decrease in lacrimal control in the surgical group within two to three months of denervation. Four participants in the second study had 35 dB to 50 dB of sensorineural hearing loss at 4000 Hz, and three had tinnitus. Because of the small numbers and trial design we also considered the adverse effects evidence very uncertain (2 RCTs, 65 participants; very low-certainty evidence). AUTHORS' CONCLUSIONS There is very low-certainty evidence from RCTs or quasi-RCTs on surgery for the early management of Bell's palsy, and this is insufficient to decide whether surgical intervention is beneficial or harmful. Further research into the role of surgical intervention is unlikely to be performed because spontaneous or medically supported recovery occurs in most cases.

Abstract
Abstract
Background
The annual incidence of Bell’s palsy (BP) is 15 to 20 per 100,000 with 40,000 new cases each year, and the lifetime risk is 1 in 60. For decades, clinicians have searched the prognostic tests of sufficient accuracy for acute facial paralysis.
Objective
The present study was designed to verify in BP which clinical or electrophysiological parameters could be considered as predictive of the degree of recovery of normal facial muscle function.
Methods
Sixty-three patients with BP were initially assessed according to the House and Brackmann facial function scoring system “HB system”. All patients were followed for 3 months, the functional recovery then reassessed according to HB system. Nerve conduction studies were measured on the affected side via a bipolar surface stimulator placed over the stylomastoid foramen.
Results
We could not find statistically significant differences between BP with good and poor prognosis as regard age, sex, onset, diabetes, hypertension, dyslipidemia, or the initial HB Score. Compound motor action potential amplitude (CMAP) detected during the initial electroneurography (ENoG) was statistically significant between BP with good and poor prognosis.
Conclusions
The initial ENoG is more predictive of recovery of Bell’s palsy than the initial clinical grading using the HB system. Age, sex, hypertension, diabetes, and dyslipidemia do not seem to correlate with the degree of recovery in Bell’s palsy.

Abstract
ABSTRACT Patients with peripheral facial paralysis (PFP) have some degree of recovery. The aim of this study was to evaluate prognostic factors and physical therapy modalities associated with functional recovery in patients with PFP. This is a cohort study with 33 patients. We collected the following variables of patients who underwent treatment at the rehabilitation center: age, sex, risk factors, affected side, degree of facial paralysis (House-Brackmann scale), start of rehabilitation, and therapy modality (kinesiotherapy only; kinesiotherapy with excitomotor electrotherapy; and kinesiotherapy with excitomotor electrotherapy and photobiomodulation therapy). The outcomes were: degree of facial movement (House-Brackmann) and face scale applied 90 days after treatment. Degree of PFP was associated with functional recovery (RR=0.51, 95% CI: 0.51-0.98; p=0.036). The facial movement was associated with the time to start rehabilitation (r=−0.37; p=0.033). Lower facial comfort was observed among women, worse ocular comfort was associated with diabetes mellitus, worse tear control with prior PFP, and worse social function with the degree of PFP. Our results indicate that the all modalities present in this study showed the same result in PFP. Recovery of PFP was associated with degree of nerve dysfunction, the length of time to onset of rehabilitation, female sex, hypertension, diabetes mellitus, and previous PFP, all of which were associated with worse outcomes on the face scale.

Abstract
OBJECTIVE This study aimed to investigate the utility of facial nerve ultrasonography in the functional and structural assessment of early-stage Bell's palsy and the prognostic value of facial nerve ultrasonography in Bell's palsy. STUDY DESIGN Prospective longitudinal study. SETTING Single center, a university-affiliated neurology clinic. SUBJECTS AND METHODS Patients with unilateral Bell's palsy who had visited our clinic within 3 days of symptom onset were enrolled in this study. Demographic information and House-Brackmann grade were collected. Electrophysiologic studies and facial nerve ultrasonography were then performed. The facial nerves on each side were scanned longitudinally with a 5- to 12-MHz probe. The diameter of the facial nerves with and without the sheath was measured at the proximal and distal portions. Follow-up examinations, including House-Brackmann grade analysis, electrophysiologic studies, and facial nerve ultrasonography, were performed after 2 months. RESULTS Fifty-four patients with unilateral Bell's palsy were enrolled, and 22 underwent the follow-up examinations. The diameters of the facial nerves were larger on the affected side than on the unaffected side at the proximal and distal portions (P < .01). On the affected side, the enlarged facial nerve at the proximal portion had decreased in size after 2 months (P < .05). The initial ultrasonography findings were positively correlated with the initial severity of Bell's palsy, but they did not predict prognosis. CONCLUSION Ultrasonography could be a useful tool for evaluating the facial nerve in Bell's palsy. Nevertheless, further studies are needed to demonstrate its prognostic value.

PATIENTS There were 18 patients who met surgical criteria: immediate complete paralysis, greater than 90% degeneration on electroneurography (ENoG), and no voluntary electromyography (EMG) potentials within 14 days after trauma and 1 year minimum follow-up. INTERVENTION MF approach for traumatic facial paralysis and for irreversible injuries nerve grafting was performed. MAIN OUTCOME MEASURE Long-term facial function, hearing results, and surgical complications. RESULTS At MF decompression, 11 patients had an anatomically intact facial nerve. Of these patients with intact nerves, 72.7% obtained normal to near normal facial function (HB I or II) at 1 year: 27.3% to HB I, 45.5% to HB II, and 27.3% to HB III. At surgery, seven patients were found to have injuries that required nerve grafting and 100% improved to HB III. For all patients, facial nerve function significantly improved after surgery (p < 0.01). The average difference in pure tone average and word recognition after surgery was +2.9 dB and +3.3%, respectively (p = 0.44; p = 0.74). Minor, transient complications occurred in three patients and an abscess required drainage in one patient, but no other major complications. CONCLUSION In our series, all patients with traumatic complete paralysis and poor facial prognosis achieved a long-term outcome of HB III or better after MF approach for decompression and repair of the facial nerve.

Abstract
The estimated incidence of acute facial paralysis is approximately 30 patients per 100000 populations annually. Facial paralysis is an extremely frightening situation and gives extreme stress to patients because obvious disfiguring face may cause significant functional, aesthetic, and psychological disturbances. For stressful patients with acute facial paralysis, it is very important for clinicians to answer the questions like whether or not their facial function will return to normal, how much of their facial function will be recovered, and how long this is going to take. It is also important for clinicians to treat the psychological aspects by adequately explaining the prognosis, in addition to providing the appropriate medical treatment. For decades, clinicians have used various electrophysiologic tests, including the nerve excitability test, the maximal stimulation test, electroneurography, and electromyography. In particular, electroneurography is the only objective measure that is useful in early stage of acute facial paralysis. In this review article, we first discuss the pathophysiology of injured peripheral nerve. And then, we describe about various electrophysiologic tests and discuss the electroneurography extensively.

Abstract
BACKGROUND The management of Bell's palsy has been the subject of much debate, with corticosteroids being the preferred medication. However, evidence also supports the use of antiviral drugs for severe cases and even decompression surgery in patients who, despite medical treatment, are not recovering. METHOD A literature review was conducted on the management of Bell's palsy. RESULTS This paper describes the background, statistical evidence, study results and pathophysiological theories that support more aggressive treatment for patients with severe palsy and those who have inadequate recovery. CONCLUSION Combination therapy including antiviral medication significantly improves outcomes in patients with severe Bell's palsy. Decompression should be considered in patients who have not recovered with drug treatment.

Abstract
OBJECTIVES/HYPOTHESIS We compared the prognostic value of different placements measured by electroneurography (ENoG) in Bell's palsy, especially among patients with poor results on ENoG. STUDY DESIGN Retrospective study using electrodiagnostic data and medical chart review from August 2006 to June 2013 was performed of patients who were diagnosed with Bell's palsy. METHODS We included 81 patients treated from August 2006 to June 2013. Initial and final facial function was established clinically by the House-Brackmann scale. Final state of facial palsy was estimated after 6 months from onset of facial palsy. Patients with less than 10% of ENoG response (more than 90% degeneration) were divided into three groups according to ENoG response by electrode placement as follows: group A, ENoG for orbicularis oculi (oculi) ≥ 10% and ENoG for nasolabial fold (NLF) < 10%; group B, ENoG (oculi) < 10% and ENoG (NLF) ≥ 10%; and group C, ENoG (oculi) < 10% and ENoG (NLF) < 10%. RESULTS There were no differences in demographic data among the three groups in terms of age, gender, initial paralysis, and days from the onset to ENoG. The complete/nearly complete recovery rates were the following: group A, 49.9%; group B, 75%; group C, 32%. The overall incomplete recovery rate in groups A and C was significantly worse than group B, and group C was the worst (P < 0.05). CONCLUSION The results suggest that ENoG of the NLF has more prognostic value in the outcomes of Bell's palsy than ENoG of the oculi, with poorest results in patients with the NLF < 10%.

Abstract
OBJECTIVE Bell's palsy, named after the Scottish anatomist, Sir Charles Bell, is the most common acute mono-neuropathy, or disorder affecting a single nerve, and is the most common diagnosis associated with facial nerve weakness/paralysis. Bell's palsy is a rapid unilateral facial nerve paresis (weakness) or paralysis (complete loss of movement) of unknown cause. The condition leads to the partial or complete inability to voluntarily move facial muscles on the affected side of the face. Although typically self-limited, the facial paresis/paralysis that occurs in Bell's palsy may cause significant temporary oral incompetence and an inability to close the eyelid, leading to potential eye injury. Additional long-term poor outcomes do occur and can be devastating to the patient. Treatments are generally designed to improve facial function and facilitate recovery. There are myriad treatment options for Bell's palsy, and some controversy exists regarding the effectiveness of several of these options, and there are consequent variations in care. In addition, numerous diagnostic tests available are used in the evaluation of patients with Bell's palsy. Many of these tests are of questionable benefit in Bell's palsy. Furthermore, while patients with Bell's palsy enter the health care system with facial paresis/paralysis as a primary complaint, not all patients with facial paresis/paralysis have Bell's palsy. It is a concern that patients with alternative underlying etiologies may be misdiagnosed or have unnecessary delay in diagnosis. All of these quality concerns provide an important opportunity for improvement in the diagnosis and management of patients with Bell's palsy. PURPOSE The primary purpose of this guideline is to improve the accuracy of diagnosis for Bell's palsy, to improve the quality of care and outcomes for patients with Bell's palsy, and to decrease harmful variations in the evaluation and management of Bell's palsy. This guideline addresses these needs by encouraging accurate and efficient diagnosis and treatment and, when applicable, facilitating patient follow-up to address the management of long-term sequelae or evaluation of new or worsening symptoms not indicative of Bell's palsy. The guideline is intended for all clinicians in any setting who are likely to diagnose and manage patients with Bell's palsy. The target population is inclusive of both adults and children presenting with Bell's palsy. ACTION STATEMENTS: The development group made a strong recommendation that (a) clinicians should assess the patient using history and physical examination to exclude identifiable causes of facial paresis or paralysis in patients presenting with acute-onset unilateral facial paresis or paralysis, (b) clinicians should prescribe oral steroids within 72 hours of symptom onset for Bell's palsy patients 16 years and older, (c) clinicians should not prescribe oral antiviral therapy alone for patients with new-onset Bell's palsy, and (d) clinicians should implement eye protection for Bell's palsy patients with impaired eye closure. The panel made recommendations that (a) clinicians should not obtain routine laboratory testing in patients with new-onset Bell's palsy, (b) clinicians should not routinely perform diagnostic imaging for patients with new-onset Bell's palsy, (c) clinicians should not perform electrodiagnostic testing in Bell's palsy patients with incomplete facial paralysis, and (d) clinicians should reassess or refer to a facial nerve specialist those Bell's palsy patients with (1) new or worsening neurologic findings at any point, (2) ocular symptoms developing at any point, or (3) incomplete facial recovery 3 months after initial symptom onset. The development group provided the following options: (a) clinicians may offer oral antiviral therapy in addition to oral steroids within 72 hours of symptom onset for patients with Bell's palsy, and (b) clinicians may offer electrodiagnostic testing to Bell's palsy patients with complete facial paralysis. The development group offered the following no recommendations: (a) no recommendation can be made regarding surgical decompression for patients with Bell's palsy, (b) no recommendation can be made regarding the effect of acupuncture in patients with Bell's palsy, and (c) no recommendation can be made regarding the effect of physical therapy in patients with Bell's palsy.

Abstract
BACKGROUND Bell's palsy is an acute paralysis of one side of the face of unknown aetiology. Bell's palsy should only be used as a diagnosis in the absence of all other pathology. As the proposed pathophysiology is swelling and entrapment of the nerve, some surgeons suggest surgical decompression of the nerve as a possible management option. This is an update of a review first published in 2011. OBJECTIVES To assess the effects of surgery in the management of Bell's palsy. SEARCH METHODS On 29 October 2012, we searched the Cochrane Neuromuscular Disease Group Specialized Register, CENTRAL (2012, Issue 10), MEDLINE (January 1966 to October 2012) and EMBASE (January 1980 to October 2012). We also handsearched selected conference abstracts for the original version of the review. SELECTION CRITERIA We included all randomised or quasi-randomised controlled trials involving any surgical intervention for Bell's palsy. We compared surgical interventions to no treatment, sham treatment, other surgical treatments or medical treatment. DATA COLLECTION AND ANALYSIS Two review authors independently assessed whether trials identified from the searches were eligible for inclusion. Two review authors independently assessed the risk of bias and extracted data. MAIN RESULTS Two trials with a total of 69 participants met the inclusion criteria. The first study considered the treatment of 403 people but only included 44 participants in the surgical trial, who were randomised into surgical and non-surgical groups. However, the report did not provide information on the method of randomisation. The second study randomly allocated 25 participants into surgical or control groups using statistical charts. There was no attempt in either study to conceal allocation. Neither participants nor outcome assessors were blind to the interventions, in either study. The first study lost seven participants to follow-up and there were no losses to follow-up in the second study.Surgeons in both studies decompressed the nerves of all the surgical group participants using a retroauricular approach. The primary outcome was recovery of facial palsy at 12 months. The first study showed that the operated group and the non-operated group (who received oral prednisolone) had comparable facial nerve recovery at nine months. This study did not statistically compare the groups but the scores and size of the groups suggested that statistically significant differences are unlikely. The second study reported no statistically significant differences between the operated and control (no treatment) groups. One operated participant in the first study had 20 dB sensorineural hearing loss and persistent vertigo. We identified no new studies when we updated the searches in October 2012. AUTHORS' CONCLUSIONS There is only very low quality evidence from randomised controlled trials and this is insufficient to decide whether surgical intervention is beneficial or harmful in the management of Bell's palsy.Further research into the role of surgical intervention is unlikely to be performed because spontaneous recovery occurs in most cases.

Abstract
OBJECTIVES To investigate the correlation between electroneurography (ENoG) findings and the prognosis of Bell's palsy in children compared with adults. METHODS Twenty-two children and 92 adults with Bell's palsy who underwent ENoG between 8 days and 4 weeks from the onset of symptoms were retrospectively enrolled. The time to maximal recovery and rate of favorable recovery (House-Brackmann grade I or II) was assessed. Children (C) and adults (A) were further subdivided into low (<10%) or high (≧10%) subgroups according to their ENoG values (affected versus unaffected side) at initial evaluation. The numbers in each subgroup were as follows: C-low (n = 8), A-low (n = 21), C-high (n = 14), and A-high (n = 71). RESULTS Of the 22 children assessed, 2 of the 4 patients who showed a total loss of evoked potentials on the affected side (0% ENoG value) exhibited an unfavorable recovery. The remaining 20 patients achieved a favorable recovery eventually. Patients in group C-low reached a maximal recovery of facial movement significantly later than those in group C-high (p < 0.001). Time to maximal recovery of facial movement in group A-low was later than that in group C-low, although the difference was not statistically significant (p = 0.15). The patients in group A-high reached a maximal recovery significantly later than those in group C-high (p < 0.05). CONCLUSION Bell's palsy seems to recover earlier in children than adults when matched for severity. The presence of an identifiable response in ENoG, irrespective of its amplitude, may indicate a favorable recovery of facial movement in children.

Abstract
PURPOSE Patients with Ramsay Hunt syndrome have a poorer prognosis than those with Bell palsy despite the use of various treatment modalities. We compared the clinical characteristics, treatment methods, and outcomes in patients with Ramsay Hunt syndrome and Bell palsy. MATERIALS AND METHODS Patients with Ramsay Hunt syndrome were compared with patients with Bell palsy treated using oral steroids and with those treated with both steroids and an antiviral agent. Functional recovery of the facial nerve was scored according to the House-Brackmann grading system. Patients were followed up until recovery or for 3 months. Recovery rates in each group were assessed by age, sex, and initial and last House-Brackmann grade. RESULTS Compared with patients with Bell palsy, those with Ramsay Hunt syndrome were generally younger, had initially more severe facial palsy, and a lower recovery rate. Various factors including initial House-Brackmann grade, starting time to treatment, age, comorbid disease, electroneurography, and electromyography showed some correlations with prognosis in all groups. The addition of antiviral agents to an oral steroid regimen did not improve the recovery rate of patients with Bell palsy. CONCLUSION Patients with Ramsay Hunt syndrome have a poorer prognosis than do those with Bell palsy.

Abstract
Management of traumatic facial nerve disorders is challenging. Facial nerve decompression is indicated if 90–95% loss of function is seen at the very early period on ENoG or if there is axonal degeneration on EMG lately with no sign of recovery. Middle cranial or translabyrinthine approach is selected depending on hearing. The aim of this study is to present retrospective review of 10 patients with sudden onset complete facial paralysis after trauma who underwent total facial nerve decompression. Operation time after injury is ranging between 16 and105 days. Excitation threshold, supramaximal stimulation, and amplitude on the paralytic side were worse than at least %85 of the healthy side. Six of 11 patients had HBG-II, one patient had HBG-I, 3 patients had HBG-III, and one patient had HBG-IV recovery. Stretch, compression injuries with disruption of the endoneurial tubules undetectable at the time of surgery and lack of timely decompression may be associated with suboptimal results in our series.

Abstract
Facial nerve paralysis in children may occur as a complication of infections, trauma, or rarely from benign or malignant tumors of the facial nerve. We present the first reported case of a dermoid tumor in the facial nerve causing facial paralysis in a child. Case report at a tertiary Children's Hospital. A 9-month-old was referred to our institution for evaluation of persistent, complete right sided facial paralysis three months after receiving a diagnosis of Bell's palsy. A workup at our institution including MRI and CT revealed marked widening of the facial canal in the mastoid segment consistent with facial nerve schwannoma or hemangioma. Surgical exploration via mastoidectomy and facial nerve decompression revealed keratinous material containing hair that had fully eroded the facial nerve, disrupting it completely. The entire tumor was removed along with the involved segment of facial nerve, and the missing facial nerve segment was cable grafted. Histological examination of the tumor confirmed a ruptured dermoid cyst in the facial nerve. Facial nerve tumors are rare causes of facial paralysis in children, accounting for fewer than 10% of cases of facial paralysis in the pediatric population. Dermoid cyst can occur throughout the head and neck region in children, but a dermoid tumor in the facial nerve has not been described in the literature prior to this report. This represents a new and uncommon diagnostic entity in the evaluation of facial nerve paralysis in children. Appropriate imaging studies and pathology slides will be reviewed.

Abstract
ABSTRACT Limited evidence may support the application of electrical stimulation in the subacute and chronic stages of facial palsy, yet some physiotherapists in South Africa have been applying this modality in the acute stage in the absence of published evidence of clinical efficacy. This preliminary study's aim was to determine the safety and potential efficacy of applying electrical stimulation to the facial muscles during the early phase of Bells palsy. A pretest posttest control vs. experimental groups design composed of 16 patients with Bell's palsy of less than 30 days' duration. Adult patients with clinical diagnosis of Bell's palsy were systematically (every second patient) allocated to the control and experimental groups. Each group (n = 8) was pretested and posttested using the House-Brackmann index. Both groups were treated with heat, massage, exercises, and a home program. The experimental group also received electrical stimulation. The House-Brackmann Scale of the control group improved between 17% and 50% with a mean of 30%. The scores of the experimental group ranged between 17% and 75% with a mean of 37%. The difference between the groups was not statistically significant (two-tailed p = 0.36). Electrical stimulation as used in this study during the acute phase of Bell's palsy is safe but may not have added value over spontaneous recovery and multimodal physiotherapy. A larger sample size or longer stimulation time or both should be investigated.

Abstract
OBJECTIVE We examined the relationship between the time course of development of facial synkinesis in patients with Bell's palsy and the severity of facial nerve damage. STUDY DESIGN Retrospective study. SETTING Tertiary referral center. PATIENTS Thirty-nine consecutive patients with Bell's palsy who developed synkinesis. INTERVENTION Diagnostic. MAIN OUTCOME MEASURES Subjects were divided into groups A (electroneurographic [ENoG] value, <10%; n = 31) and B (ENoG value, > or =10%; n = 8). Development of facial synkinesis was assessed based on the appearance of synkinetic potentials from the orbicularis oris muscle on the blink reflex test. Times to appearance of facial synkinesis in groups A and B were compared. The proportion of patients who developed facial synkinesis after complete recovery of facial movement was also assessed in 14 patients whose facial movement recovered completely. RESULTS The mean time to maximal recovery of facial movement was significantly longer in group A than in group B (p < 0.001), whereas the duration between the appearance of facial synkinesis and the onset of facial paralysis did not differ significantly between the 2 groups (p = 0.72). The proportion of patients who developed facial synkinesis after complete recovery of facial movement was significantly greater in group B than in group A (p = 0.015). CONCLUSION During the course of recovery from Bell's palsy, the patients with an ENoG value of 10% or greater have a higher risk of developing facial synkinesis after complete recovery of facial movement.

Abstract
OBJECTIVE Although it is important to have strong predictors of outcome in peripheral mononeuropathies so that appropriate management can be instituted early, little is known about the prognostic value of electrodiagnostic results for these lesions. Our objective in this study was to evaluate the prognostic value of electrodiagnostic studies in fibular neuropathy. DESIGN In this retrospective study, 39 of 138 subjects with fibular neuropathy met the inclusion criteria. Electrodiagnostic results at the time of testing were evaluated for their value in predicting outcome. Good outcome was defined as grade 4 or higher strength on the Medical Research Council Scale in ankle dorsiflexion. RESULTS Compound muscle action potential responses from extensor digitorum brevis and tibialis anterior predicted prognosis: 81% of subjects with any tibialis anterior response and 94% with any extensor digitorum brevis response had a good outcome vs. those with absent responses (46% and 52%, respectively). Importantly, there was still a high likelihood of good outcome with absent compound muscle action potential responses. Tibialis anterior compound muscle action potential gave additional prognostic information when extensor digitorum brevis response was absent. Recruitment in tibialis anterior was predictive in traumatic cases. All patients with nontraumatic compression had a good outcome. CONCLUSIONS We conclude that electrodiagnostic studies produce useful prognostic information in fibular neuropathy, particularly in traumatic cases.

Abstract
OBJECTIVES This study evaluated the accuracy of electroneurography to predict the prognosis of Bell's palsy and Ramsay-Hunt's syndrome. DESIGN A retrospective, institutional review board-approved study. SETTING A secondary referral and a university-based centre. PARTICIPANTS The patients had been treated for a sudden onset unilateral facial paralysis over the past 10 years (1994-2004). This retrospective study included only those patients who had been followed up for at least 3 months or if they had reached a complete recovery before then. MAIN OUTCOMES MEASURES House-Backmann grade versus electroneurography value. RESULTS The recovery rates to House-Brackmann grade II or better were 95% in those with Bell's palsy and 84% in those with herpes zoster oticus. The electroneurography value of the recovery and non-recovery groups from those with either Bell's palsy or herpes zoster oticus was similar. The logistic regression model between the electroneurography values and the probability of recovery showed no correlation in those with Bell's palsy or with herpes zoster oticus. This study did not identify the proper electroneurography value that had enough appropriate sensitivity and specificity to predict the prognosis of paralysis accurately in Bell's palsy or in herpes zoster oticus patients. CONCLUSION Electroneurography performed between day 7 and 10 for Bell's palsy or day 10 and 14 for herpes zoster oticus does not provide accurate information on the prognosis or recovery rate of the facial paralysis.

Abstract
OBJECTIVE To examine the agreement between clinical and electromyographic assessments during the course of facial paralysis, in order to determine whether electromyography adds more information to the clinical examination in determining voluntary and synkinetic movement. DESIGN Serial clinical and electromyographic assessments were performed. SETTINGS Physical Medicine and Rehabilitation Department of a university hospital. SUBJECTS Thirty patients with acute complete idiopathic facial paralysis were included. MAIN MEASURES Voluntary and synkinetic movements of the orbicularis oculi and orbicularis oris muscles were graded by Facial Grading System and by needle electromyography at three weeks, and two, three and six months after the onset of paralysis. Weighted kappa (kappa) statistics were performed to measure the agreement between clinical and electromyographic assessments. RESULTS Agreement between assessments yielded an overall kappa value of 0.87 for the orbicularis oculi and 0.59 for the orbicularis oris in identifying voluntary movement. electromyography revealed no voluntary movement in the orbicularis oculi, in 65% of the patients in whom slight movement was considered by clinical assessment. In identifying synkinetic movements, an overall kappa value was 0.70 for the orbicularis oculi and 0.85 for the orbicularis oris. Electromyography demonstrated many cases of slight synkinesis that were missed through visual inspection in both muscles. CONCLUSIONS Clinical evaluation provides sufficient information about recovery in voluntary movement in the orbicularis oris, whereas, in the orbicularis oculi, electromyography adds to the clinical evaluation in determining the extent of paralysis.

Abstract
OBJECTIVE This study evaluated the prognostic factors in Bell's palsy and Ramsay Hunt syndrome (HZO). METHODS A retrospective, institutional review board-approved study at a university-based hospital. A total of 81 patients consisting of 55 Bell's palsy patients and 26 HZO patients were enrolled in this study. The treatment consisted uniformly in all cases, and acyclovir was administered in the case of Ramsay Hunt syndrome. All patients were followed up until they recovered or for least up 6 months. RESULTS The recovery rates to House-Brackmann grade II or better were 96.3% in those with Bell's palsy and 84.6% in those with HZO. In the HZO cases, older patients had a poorer initial and final status, and less chance of making a complete recovery than the younger patients. The HZO patients without diabetes mellitus had a higher chance of recovery, a higher chance of complete recovery, and a better final status. In addition, HZO patients without essential hypertension had a higher degree of recovery. HZO patients not suffering from vertigo had a higher chance of recovery. CONCLUSION There was no prognostic factor found in the Bell's palsy patients in this study. The prognostic factors of HZO were age, diabetus mellitus, essential hypertension and vertigo.

Abstract
Despite being the foremost examination in the management of traumatic nerve damage electromyography (EMG) has an uncertain and ill-defined role in the investigation of brachial plexus palsy of the newborn (BPPN). This may be because EMG, which is used most commonly several months after birth, fails to answer adequately two of the most important questions posed by this condition: its aetiology and the likely prognosis. In this review, we contend that EMG has important contributions to the solution of both of these questions but only if the timing of the investigation is altered. Used early on in the first few days after birth, EMG can separate the rare palsies that occurred during the intrauterine period from those caused by events at the time of birth, and thus have an important role in directing the investigations of the aetiology more appropriately. EMG alone would still not be able to determine which of the perinatal events were responsible. If the EMG is then repeated before reinnervation complicates interpretation, it seems probable that it would identify accurately those cases, where neurotmesis and avulsion have occurred, much earlier than 3 months of age, the crucial age in the clinical assessment of BPPN for consideration for surgery. This might have very important implications for the future directions of treatment.

Abstract
Bell's palsy is a self-limiting idiopathic rapid onset facial palsy that is non-life-threatening and has a generally favorable prognosis. Facial paralysis can be caused by numerous conditions, all of which should be excluded before a diagnosis of Bell's palsy is reached. The etiopathogenesis of Bell's palsy is uncertain; acute immune demyelination triggered by a viral infection may be responsible. Controversy exists regarding treatment options. This article reviews the differential diagnosis and diagnostic and therapeutic options and discusses the controversies related to the various treatment modalities (steroids, acyclovir, and surgery). A simple practical approach to diagnosing and treating children with Bell's palsy is suggested.

Abstract
Prognosis remains a neglected aspect of modern medical care and research, behind diagnosis and treatment. The very term "electrodiagnosis" implies as much. Despite this, much has been published regarding the use and benefit of electrodiagnostic techniques in assessing prognosis and assisting in management of patients after the diagnosis has been established. This information is often hidden or otherwise not emphasized. This review summarizes the literature regarding the use of such techniques for prognosis and management of disorders of lower motor neurons, peripheral nerves, neuromuscular transmission, and muscle.

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
OBJECTIVE To analyze the value of electromyography in predicting recovery from acute idiopathic facial nerve paralysis. STUDY DESIGN Retrospective case-series review. SETTING University-based hospital department of otorhinolaryngology/head neck surgery. PATIENTS Three hundred fifty-five patients with sudden facial paralysis of unknown cause (Bell's palsy). INTERVENTION Treatment consisted uniformly of high-dose prednisolone, dextran, and pentoxifylline. Prognostication was based on electromyography performed not earlier than 10 to 14 days after the onset of palsy. The findings were classified according to Seddon into neurapraxia and axonotmesis/ neurotmesis. There is an inherent statement on prognosis in this classification because neurapraxia is presumed to recover completely within 8 to 12 weeks, whereas axonotmesis is most likely to be followed by sequelae. MAIN OUTCOME MEASURES Facial nerve function after 6 months. RESULTS Complete recovery was predicted correctly in 92.4% of cases. For the relatively rare and therefore principally more difficult predictable event defective recovery prognosis was still accurate in 80.8%. CONCLUSION The detection of spontaneous fibrillation in needle electromyography is a reliable sign predicting unfavorable outcome. An accuracy of 80.8% for predicting unfavorable outcome may be sufficient to advise patients what to expect in the course of their facial nerve disorder. However, it seems dubious to build a decision about surgical intervention on such a test, because in the process, unnecessary surgery would be accepted for as much as one fifth of the patient population.

Abstract
This article reviews the epidemiology and classification of traumatic peripheral nerve injuries, the effects of these injuries on nerve and muscle, and how electrodiagnosis is used to help classify the injury. Mechanisms of recovery are also reviewed. Motor and sensory nerve conduction studies, needle electromyography, and other electrophysiological methods are particularly useful for localizing peripheral nerve injuries, detecting and quantifying the degree of axon loss, and contributing toward treatment decisions as well as prognostication.

Abstract
To study the electroneurographic facial muscle pattern in Bell's palsy over time, electroneurographic recordings in the frontalis, orbicularis oculi, nasalis, and mentalis muscle regions were performed early (mean, day 11) and 1 and 3 months after the onset of the condition in 30 consecutive patients. The correlation between facial muscle electroneurographic recordings over time was also calculated. An additional aim was to assess whether further prognostic information could be obtained by electroneurographic recordings in more than one facial region. The recovery pattern was similar in all 4 facial regions. Initially, the correlation between the facial recordings was weak (r = 0.20-0.27), but it was improved at follow-up examinations (r = 0.33-0.65). Favorable outcome in 23 of 24 patients (96%) could have been predicted by the initial nasalis and/or mentalis recordings. The gap between patients with favorable outcome and patients with unfavorable outcome increased when the average electroneurography values were calculated from 1, 2, and 4 muscle recordings (4%, 8%, and 15%, respectively). Our results indicate that in Bell's palsy, electroneurographic examination of more than one facial muscle region may add prognostic information and that the degree of degeneration is initially different in the nerve branches.

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.

Abstract
BACKGROUND Facial electroneurography (ENoG) is an established and reliable method for assessing neural degeneration in various conditions affecting the facial nerve. The facial nerve may be subclinically involved by parotid tumors, but estimating such involvement preoperatively may be difficult when facial function is normal. The hypothesis that preoperative ENoG: (1) can detect subclinical facial nerve degeneration as a measure of involvement by parotid tumors and (2) can predict facial nerve function following parotidectomy was prospectively evaluated in the present study. METHODS Twenty-two patients undergoing parotidectomy for tumors were tested preoperatively with ENoG, and their facial nerve function was graded pre- and postoperatively (House-Brackmann system). Eight patients had malignant tumors and 14 benign tumors. RESULTS In patients with malignant tumors, lower percentage of preoperative ENoG response indicated nerve involvement that was not evident on clinical examination and correlated significantly (p = .035) with postoperative facial nerve dysfunction. Preoperative ENoG reduction of greater than 80% was found in all patients whose facial nerve was infiltrated by tumor. In 14 patients with benign tumors, preoperative ENoG results had no correlation with postoperative facial function. CONCLUSIONS In malignant tumors, even when facial function is clinically intact, a low preoperative ENoG response may predict facial nerve involvement by the tumor. The lower the preoperative ENoG response, the poorer is the expected postoperative facial nerve function. There was no such correlation in benign parotid tumors.
