Facial nerve palsy in otitis externa: A red flag?

Otitis externa is an infection of the external auditory canal. It rarely results in facial palsy except in severe cases such as necrotizing otitis externa, which is a life-threatening invasive infection of the external auditory canal. Early recognition with prompt and appropriate treatment of necrotizing otitis externa is crucial to prevent more sinister complications. Here we report a case of an elderly gentleman who presented with otitis externa and developed facial palsy a month later. We identified possible problems that may have led to the complication so that such an occurrence can be prevented in the future.

The great pretender-Bell's palsy secondary to SARS-CoV-2?

This case series highlights a possible association between isolated facial nerve palsy and SARS-CoV-2. Caution should be exercised in the use of steroids in patients with COVID-19 as its impact is still not well established.

Recurrent Facial Palsy Due to High Jugular Bulb Dehiscence

Background

A high mega jugular Bulb is an enlarged and swollen upper portion of the internal jugular vein with a variation of its anatomical position among the population, mostly situated below the hypotympanum. Although most cases of jugular bulb diverticulum are asymptomatic, excessive pressure on the surrounding structures might cause various symptoms, most prominently vertigo, sensorineural hearing loss, or tinnitus.

Case Report

A middle-aged male who was referred to the Department of Neurology with a recurrent complaint of left-sided facial weakness associated with headache and vertigo for a period of 24 months. His symptoms were episodic, furthermore exacerbated by visiting high altitude sites. Non-resolving with conventional medical treatment. After thorough investigation, including preoperative and postoperative audiograms, neuroimaging, including computed tomography as well as magnetic resonance angiography, he was diagnosed to have right-sided superior mega jugular bulb as a causative factor. After surgical management, the patient improved significantly. At his regular follow-up in our clinic there were no exacerbations of his symptoms.

Conclusion

Among patients who present with recurrent non-resolving facial palsy in which no apparent causative factor is identified, high jugular bulb should be suspected and investigated. Comprehensive and detailed medical history is essential for raising the suspicion for the diagnosis. Such as the case presented eliciting high altitudes as the main precipitating factor. The diagnosis is clinically elusive, commonly obscured by other common diagnoses. Surgery is recommended if antihypertensive drugs do not show improvement.

Efficacy of surgical treatment in patients with post-traumatic facial nerve palsy

INTRODUCTION

The most common mechanism of post-traumatic facial nerve palsy are road accidents and falls. Treatment schemes as well as proper timing of surgery are still controversial. <br/><br/>Aim: The aim of the study was the evaluation of the effects of surgical treatment in patients with post-traumatic facial nerve palsy. Treatment results were correlated with epidemiological factors, mechanism of injury, level of nerve damage, time of surgery and its extent. <br/><br/>Material and methods: 9 patients with facial nerve palsy after head trauma were analyzed. In all patients complete paresis of the VII nerve occurred immediately after the injury. In 5 patients the nerve was damaged in the course of the longitudinal fracture of the temporal bone, in 3 as a result of its transverse fracture while in one woman there was no evident fracture line. In all cases, surgical treatment was performed between 4 days and 13 weeks after the trauma. In all cases transmastoid approach was used. Edema lesions of the nerve dominated in 6 patients, in two cases a bone fragment was noted along its course, in one person nerve was disrupted but primary reconstruction was not possible - the man was excluded from further analysis. The results of treatment were assessed by House-Brackmann (HB) scale 12 months after the procedure. <br/><br/>Results: Very good (HBI) or good (HBII) recovery of facial nerve function was achieved in 2 and 4 out of 8 patients respectively. Surgical timing, the extent of surgery, patient's age, mechanism of injury and level of nerve damage had no effect on the final outcome. <br/><br/>Conclusions: The management of post-traumatic facial nerve palsy should be individual. The commonly accepted recommendation on surgical treatment is to undertake it in patients with immediate-onset and complete paralysis. Patients who, due to their severe general condition, cannot undergo early facial nerve decompression may benefit from delayed treatment for up to 3 months after the injury.

Predicting Factors Influencing Visual Function of the Eye in Patients with Unresolved Facial Nerve Palsy after Upper Eyelid Gold Weight Loading

Implantation of gold weights into the upper eyelid is a proven method of treating lagophthalmos and exposure keratopathy in patients with unresolved facial nerve palsy. The aim of this study was to evaluate the factors affecting visual acuity and corneal complications in patients after upper eyelid gold weight lid loading. Material and methods: This prospective consecutive clinical study was conducted in years 2012–2018. In total, 59 people (40 women, 19 men aged 55.5 ± 17.4 years) meeting the inclusion criteria were treated with gold weights. The ordered multinomial logit model was used to analyze the factors affecting best-corrected visual acuity (BCVA) and degree of exposure keratopathy after surgery. The influence of the following variables was analyzed: patient age, etiology and duration of the facial nerve palsy, history of the previous eyelid surgery, degree of lagophthalmos in mm, presence of Bell’s phenomenon, and corneal sensation, Schirmer test results. Results: Implantation of gold weights into the upper eyelid effectively reduced lagophthalmos and exposure keratopathy in the study group (p < 0.001). BCVA was maintained or better in 95% of patients after surgery. Patient age, presence of the Bell’s phenomenon, and corneal sensation significantly affected the final BCVA (p < 0.1). The presence of Bell’s phenomenon and corneal sensation had a positive effect on the degree of keratopathy after surgery (p < 0.1). In turn, patient age and history of tarsorrhaphy were significant negative prognostic factors of exposure keratopathy and BCVA after surgery (p < 0.05). Etiology and duration of facial nerve palsy, degree of corneal exposure in mm, and results of the Schirmer test did not have a significant impact on the outcome after surgery (p > 0.1). Conclusions: The results of our study may help to answer the question of how to direct ophthalmologists and other specialists who refer to ophthalmologists for management advice in patients with facial nerve palsy. Elderly patients with a history of tarsorrhaphy who present with poor Bell’s phenomenon and/or a lack of corneal sensation should be the first candidates for immediate correction of lagophthalmos.

Managing a Complicated Acute Otomastoiditis at Day Four of Life

Acute mastoiditis in a newborn complicated by the presence of facial nerve palsy is an alarming finding requiring rapid assessment and further investigation. Such an early presentation should point the clinician towards an underlying systemic pathology or congenital anatomical abnormality. Facial nerve involvement indicates severe infection and possible dehiscence of the facial canal. Although more frequent in children, it is rare in neonates. We would like to share our experience in managing the youngest known presentation of otomastoiditis at four days of life. The patient presented with otorrhea and facial paralysis and progressed to meningitis. He was finally diagnosed with chronic granulomatous disease.

Relationship Between Eyelid Pressure and Lacrimal Status in Mild Facial Nerve Palsy

Purpose: Facial nerve palsy is frequently associated with both epiphora and dry eye, and orbicularis oculi muscle weakness or paralysis is the main cause of these symptoms. Eyelid pressure is a quantitatively measurable parameter for evaluating the tone and function of the orbicularis oculi muscle. The aim of this study was to examine the relationship between eyelid pressure and lacrimal status in patients with mild facial nerve palsy.

Methods: This prospective, interventional study included 10 patients with unilateral facial nerve palsy. The severity of facial nerve palsy was determined using the CADS scale (cornea, static asymmetry, dynamic function, and synkinesis). Eyelid pressure was measured using a blepharo-tensiometer. Lacrimal status was quantified through tear meniscus height (TMH), clinical assessment of meibomian gland dysfunction (MGD) (eyelid margin abnormalities, Marx line, meibum expression, and loss of meibomian glands), corneal fluorescein staining, tear break-up time, and Schirmer test I results.

Results: All 10 patients suffered from mild facial nerve palsy without eyelid ectropion or entropion, or gustatory epiphora. Lower eyelid pressure during forceful eye closure was significantly decreased in affected eyes (P = 0.007), but upper eyelid pressure during forceful eye closure and static upper and lower eyelid pressure were not significantly different between the affected and unaffected sides (P > 0.050). The TMH, MGD, and dry eye measurements showed no significant difference between the affected and unaffected eyes (P > 0.050).

Conclusions: Mild facial nerve palsy is associated with decreased lower eyelid pressure during forceful eye closure. However, no other differences in upper eyelid pressure during forceful eye closure, static eyelid pressure, TMH, MGD, or dry eye disease symptoms were noted. These results imply that eyelid pressure slightly decreases due to mild facial nerve palsy, but this change may be clinically negligible.

Coronary artery aneurysm and facial drooping in a infant with Kawasaki disease

Kawasaki disease is the leading cause of acquired heart disease in infants and young children. Kawasaki disease that manifests as facial nerve palsy is extremely rare, and the diagnosis is challenging. We report a 4-month-old girl with Kawasaki disease who presented with fever, redness and cracking in the lips and oral cavity, and a right facial nerve palsy. The infant received intravenous immunoglobulin, acetyl salicylic acid, and warfarin. The patient's fever subsided on the following day, and the right-sided facial nerve palsy was relieved a month later.

Facial Nerve Paralysis Following Endovascular Embolization: A Case Report and Review of the Literature

OBJECTIVE

We report a case of facial nerve paralysis post-endovascular embolization of a sigmoid sinus dural arterio-venous fistula from initial presentation to current management and discuss the merits of observation versus decompression through a systematic review of relevant literature.

PATIENT

61 F with right facial palsy.

INTERVENTION

Following a single intravenous dexamethasone injection with oral steroids over 2 months, patient was observed with no additional treatment other than Botox chemodenervation and facial rehabilitation.

OUTCOME AND RESULTS

The patient initially presented with complete right facial palsy (HB 6/6). Post-op CT imaging indicated Onyx (ev3, Irvine, California, USA) particles present at the geniculate segment of the facial nerve. Observation was chosen over surgical intervention. At the most current follow up of 8 months, facial function has improved substantially (HB 2/6).

CONCLUSION

Facial palsy is a serious, though rare, complication of transarterial endovascular embolization. With our case report and literature review, we highlight not only how conservative observation is the recommended treatment, but also that facial nerve recovery should be expected to reach near complete recovery, but not sooner than in 3 months.

Atypical teratoid rhabdoid tumor (AT/RT) at the cerebellopontine angle arising from acoustic nerve with facial nerve palsy: report of a case

Atypical teratoid rhabdoid tumor (AT/RT) is a highly aggressive central nervous system embryonic tumor predominantly occurring in infants and young children. The AT/RT can occur in the cerebellopontine angle and cause facial nerve palsy as a presenting sign. We present a case of a 2-year-old girl with a cerebellopontine angle tumor who initially presented with acute facial palsy. Later, asubsequent diagnosis of AT/RT was made.

Quality of Life in Patients with Unresolved Facial Nerve Palsy and Exposure Keratopathy Treated by Upper Eyelid Gold Weight Loading

Background

Loading of the upper eyelid with gold weights is a well-established procedure for the correction of paralytic lagophthalmos. There is no reliable research evaluating the results of this treatment from the patients’ viewpoint.

Aim

The aim of this research was to evaluate quality of life (QOL) domains through two standardized questionnaires (SF-36 and NEI-VFQ39) in patients treated by upper eyelid gold weight loading compared to healthy individuals (the “healthy” group) as well as patients with other ophthalmologic conditions (the “sick” group).

Patients and Methods

This prospective comparative clinical study of 416 surveys was conducted in 2012–2018. The study group includes 59 people: 40 women, 19 men aged 55.5 ± 17.4 treated with gold weights for corneal complications due to unresolved facial nerve palsy. General QOL was assessed using the SF-36 questionnaire. Eye-related QOL was assessed through the NEI-VFQ39 questionnaire. The results were compared with those obtained in 2 control groups: the “healthy” and the “sick,” 53 individuals each.

Results

A statistically significant increase in QOL domains was noted in patients with facial nerve palsy after treatment (p<0.001). No statistically significant differences were found in categories defining the Physical Component Score in these patients as compared to those from the “sick” control group (p = 0.95). After surgery, the results of the Mental Component Score were comparable to those in the “healthy” control group (p = 0.51). The eye-related health scores changed significantly after surgery and differed significantly compared to the “sick” control group (p <0.05); however, they did not reach the level of the “healthy” control group (p <0.001).

Conclusion

Patients with untreated facial nerve palsy had the lowest QOL levels among all individuals involved in this study. Treatment of lagophthalmos by gold weights significantly improved their QOL, with the greatest impact on mental aspects of health.

Intravenous Vitamin C as Ancillary Treatment for Cranial Polyneuritis and Meningitis due to Varicella Zoster Virus Reactivation

A 65-year-old Japanese woman developed vesicular eruptions on her right ear due to varicella zoster virus (VZV) reactivation, followed by cranial polyneuritis and meningitis affecting her right cranial nerves V, VII, VIII, IX, and X. After acyclovir administration, her facial paralysis worsened. Intravenous methylprednisolone and vitamin C were administered on Day 4 post-admission. Her symptoms steadily improved, and by Day 45 she had fully recovered. Cranial polyneuritis is a rare complication of VZV reactivation, and there is no established method of treatment. This is the first report of full recovery from cranial polyneuritis using intravenous vitamin C as ancillary treatment.

Guillain-Barre Syndrome, Neuroborreliosis, or Both

Guillain-Barre syndrome (GBS) is an acute paralytic neuropathy. Limited reports of GBS caused by tick-borne pathogens exist. Lyme disease is a tick-borne infectious disease that is commonly caused by Borrelia burgdorferi. The nervous system may be involved and is called neuroborreliosis.

In this case, we report a 30-year-old female who presented to the emergency department with one week of diffuse, increasing weakness in the upper/lower extremities and face after a recent gastrointestinal illness and travel to the Northeastern United States. Areflexia was noted in bilateral lower extremities. Lumbar puncture results together with clinical presentation were consistent with a diagnosis of GBS. Lab results later revealed a possible Lyme infection in cerebrospinal fluid, which along with recent travel to endemic area gave high suspicion for Lyme disease. The patient was treated for both diseases with significant improvement.

Taking a good history is an essential first step in diagnosis, as travel history was key in testing for Lyme.

Malignant Otitis Externa: Causes for Various Treatment Responses

OBJECTIVES

Malignant (necrotizing) otitis externa (MOE) is an aggressive form of skin inflammation of the external ear with a tendency to spread infection to the temporal bone. The study aimed to evaluate a causal relationship between treatment responses and clinical features in patients with MOE.

MATERIALS AND METHODS

In a retrospective, descriptive section study, the database was analyzed between January 2008 and December 2018 in our department, all patients with diagnosed MOE were identified.

RESULTS

A total of 30 patients were evaluated, of which 27 men and 3 women. The youngest patient was 52 years old while he was eldest 88 years, (mean-71 years old). As the most common comorbidity, diabetes mellitus was found in 23 (76%) subjects. Median duration of symptoms was about 3 months. The most common isolated pathogen was Pseudomonas aeruginosa (47%). Patients with facial nerve palsy and erosion of temporal bone find on computerized tomography affect prolonged stationary treatment (Mean, SD 29.2±8.5 and 26,7±11.6 days), while 80% of patients with facial nerve palsy had recurrence of disease (p=0.005) with mean duration of clinical remission of 60±17.3 days. Overall length of treatment is also increased in the presence of comorbidities as well as in patients with cranial nerve involvement.

CONCLUSION

Patients with cranial nerve involvement, erosion of temporal bone and presence of comorbidities affect prolonged treatment and adverse prognosis. Early diagnosis and initiation of aggressive therapy are essential for stopping the further spread of the disease and prevention of serious complications.

Coronavirus Disease-19 Pneumonia with Facial Nerve Palsy and Olfactory Disturbance

The novel coronavirus disease-2019 (COVID-19), caused by severe acute respiratory syndrome coronavirus-2, has spread worldwide from China. There are no case reports from Asia of COVID-19 with facial paralysis and olfactory disturbance. We herein report a case of COVID-19 pneumonia in a Japanese woman who showed facial nerve palsy and olfactory disturbance.

The diagnostic value of cytology in parotid Warthin's tumors: international multicenter series

INTRODUCTION

Warthin's tumor (WT) is a common benign salivary gland neoplasm with a negligible risk of malignant transformation. However, there is a risk of malignant tumors being misdiagnosed as WT on cytology and inappropriately managed conservatively.

METHODS

Patients from nine centers in Italy and the United Kingdom undergoing parotid surgery for cytologically diagnosed WT were included in this multicenter retrospective series. Definitive histology was compared with preoperative cytological diagnoses. Surgical complications were recorded.

RESULTS

A total of 496 tumors were identified. In 88.9%, the final histological diagnosis was WT. In 21 cases (4.2%) a malignant neoplasm was diagnosed, which had been incorrectly labeled as WT on cytology.

CONCLUSIONS

The risk of undiagnosed malignancy should be balanced against surgical risks when considering the management of WT. Although nonsurgical management remains an appropriate option, there may be a rationale for serial clinical or radiological evaluation if surgical excision is not performed.

Miller Fisher syndrome with early intracranial hypertension and delayed bilateral simultaneous facial nerve palsy: a case report

Miller Fisher syndrome (MFS), a variant of Guillain–Barré syndrome, is characterized by ataxia, areflexia and ophthalmoplegia. This case report describes a 40-year old male that presented with a 3-day history of unsteady walking and numbness on both hands, and a 2-day history of seeing double images and unclear articulation. Lumbar puncture revealed an opening pressure of 260 mm H₂O. Plasma serology was positive for anti-ganglioside M1-immunoglobulin M (anti-GM1-IgM) antibodies and negative for anti-ganglioside Q1b (anti-GQ1b) antibodies. The patient was diagnosed with MFS based on the clinical course and neurophysiological findings. On the 4th day of treatment with intravenous immunoglobulin (IVIG), his ataxia and unsteady walking improved, but his bilateral eyeballs were fixed, and over the next few days he developed bilateral peripheral facial paralysis. After 5 days of IVIG treatment, methylprednisolone treatment was offered and the patient's symptoms gradually improved. Early intracranial hypertension and delayed facial nerve palsy may be atypical presentations of MFS. Anti-GM1-IgM antibodies may be the causative antibodies for MFS. If the IVIG therapy does not stop the progression of the disease, the addition of corticosteroid therapy may be effective. However, the relationship between IgM type, anti-GM1 antibody and MFS remains unclear and requires further research.

Variations in Facial Nerve Branches and Anatomical Landmarks for Its Trunk Identification: A Pilot Cadaveric Study in the Lithuanian Population

Objective The purpose of this study was to evaluate facial nerve (FN) branching variations based on Davis and Kopuz classifications in the Lithuanian population and measure the shortest distance from the facial nerve trunk (FNT) to its anatomical landmarks. Methods Twenty-two hemifaces of 11 cadavers were dissected. The preauricular skin cut was made and extended behind the ear lobe and along the inferior border of the mandible. The skin with subcutaneous tissue and superficial fascia were separated and medially retracted, and the parotid gland was dissected anterogradely. The FNT and its furcation type and branching pattern were disclosed and noted based on Davis and Kopuz classifications. Further, the shortest distance from the FNT to the anatomical landmarks of the tragal pointer (TP), the angle of mandible (AM), and the tip of mastoid process (TMP) was measured. Results The prevalence of branching patterns did not differ significantly compared to Davis classification. Based on Kopuz, type IVA pattern was the most common in six cases (27%). Eighteen (82%) trunks split as bifurcations and two (9%) trifurcations, while two (9%) had separate double trunks. The shortest distance (mm) from the FNT to the TP is 9.30 ± 0.93, AM 36.45 ± 4.14, and TMP 12.52 ± 2.30. Conclusion The prevalence of FN variations in the Lithuanian population is similar to Davis classification. The AM and TMP are consistent superficial bony landmarks for trunk identification, while the distance from the TP highly varies among studies. Surgeons should be aware of double FNT during parotidectomy, which is described in Kopuz classification.

Facial nerve palsy presenting as rare neurological complication of Kawasaki disease: A case report

RATIONALE

Facial nerve palsy (FNP) is one of the rare neurologic symptoms of Kawasaki disease (KD), associated with a higher incidence of coronary arteries lesions and may be an indicator of more severe disease.

PATIENT CONCERNS

A 3-month-old male infant with persistent fever, irritability, and facial asymmetry.

DIAGNOSES

KD with FNP.

INTERVENTIONS

The infant received intravenous immunoglobulin (IVIG) (2 g/kg/16 hours) and aspirin (50 mg/kg/day) were started on the 8th day of illness.

OUTCOMES

Fever and FNP resolved within 48 hours after IVIG treatment. The inflammatory markers all improved to normal or near-normal levels before discharge; all infectious studies returned negative. His left facial weakness was unappreciable at day of discharge.

LESSONS

FNP associated with KD is an uncommon finding but may indicate an increased risk of coronary artery involvement. KD should always be kept in mind in the differential diagnosis of a child who presents with prolonged unexplained fever, even with incomplete diagnostic features, as well as the need to be aware of unusual manifestations, such as FNP.

Kawasaki disease manifesting as bilateral facial nerve palsy and meningitis: a case report and literature review

Background

Kawasaki disease (KD) is an acute multisystem vasculitic syndrome that predominantly affects infants and young children. Neurological complications are rare in patients with KD and the diagnosis is challenging. We report a case of KD that manifested as bilateral facial nerve palsy and meningitis.

Case report

A 6-month-old boy presented with a 10-day history of fever. Four days before admission, the patient developed a rash, conjunctival injection, perioral and perianal excoriation, and bilateral facial nerve palsy. Brain magnetic resonance imaging was normal. Echocardiography showed dilated coronary arteries and coronary artery aneurysms. A cerebrospinal fluid examination showed an elevated leukocyte count. A diagnosis of KD was made, and the patient was treated with gamma globulin and aspirin. The patient’s fever subsided on the following day and the right-sided facial nerve palsy was relieved 1 month later. An 18-month follow-up showed that the left-sided facial nerve palsy persisted and the patient’s condition remained stable.

Conclusion

KD manifesting as bilateral facial nerve palsy and meningitis is extremely rare. Clinicians should be aware of this condition, and early diagnosis and appropriate treatment should be emphasized.

Development of the Alberta facial clinical evaluation scale: A patient-centred outcomes instrument for facial nerve paralysis

OBJECTIVES

Facial nerve paralysis has functional, psychological and social consequences for patients. Traditionally, outcome measurements for facial nerve injuries have been clinician derived. Recent literature has shown that patient perspective is valuable and necessary in outcomes research. This study aimed to identify patient domains of concern and subsequently, develop a point-of-care questionnaire for clinical use.

DESIGN

This mixed-methods prospective study was completed in three phases. In Phase I, 15 facial nerve injury patients were interviewed individually. Interviews were digitally recorded, transcribed and coded with NVivo software. Analysis led to a conceptual framework detailing the most important quality of life outcomes. During Phase II, a focus group was held with five new patients in order to prioritise the outcome themes to a top six list. A second focus group was held with Otolaryngology-Head and Neck staff surgeons to create a 25-item questionnaire based on these six themes. In Phase III, the questionnaire was administered to 10 new patients to test for comprehension.

SETTING

University of Alberta Hospital, Edmonton, Alberta, Canada.

PARTICIPANTS

A total of 30 patients with facial nerve injury were included in the various phases in the study. In addition, 5 staff Otolaryngology-Head and Neck surgeons participated as focus group contributors.

MAIN OUTCOME MEASURES

Domains of concern and quality of life outcomes as reported by facial nerve injury patients.

RESULTS

Patients identified a total of 16 themes encompassing both functional and psychological deficits related to their facial nerve injury. From these findings, a 25-item Likert-type scale, the A-FaCE scale, was developed for clinical use.

CONCLUSIONS

Patients with facial nerve paralysis experience functional and psychological deficits. This study led to the creation of the first patient-reported instrument for this population that addresses functional impairment, social function, psychological well-being and self-perception of appearance.

Cephalic tetanus presenting with bilateral facial palsy

We discuss the case and differential diagnoses of an elderly man who presented with bilateral facial palsy. He had injured his forehead in the garden during a fall on his face and the open wound was contaminated by soil. He then presented to the emergency department with facial weakness causing difficulty speaking. The penny dropped when he started developing muscle spasms affecting his lower jaw a day after admission. It also became clear that he could not open his mouth wide (lock jaw). The combination of muscle spasms and lock jaw (trismus) made tetanus the most likely possibility, and this was proven when he had samples taken from his wound and analysed under the microscope, which showed Clostridium tetani bacilli. C. tetani spores are widespread in the environment, including in the soil, and can survive hostile conditions for long periods of time. Transmission occurs when spores are introduced into the body, often through contaminated wounds. Tetanus in the United Kingdom is rare, but can prove fatal if there is a delay in recognition and treatment.

Kawasaki disease complicating bilateral facial nerve palsy and giant coronary artery aneurysms: A case report

RATIONALE

Kawasaki disease (KD), which is also known as mucocutaneous lymphnode syndrome, is a vasculitic disease and involves multi-system disorder with various clinical manifestations. KD is specific predilection for the coronary arteries and is the most common cause of childhood-acquired heart disease in developed countries. KD is rarely complicated by cranial nerve VII palsy.

PATIENT CONCERNS

This report described a 7-month-old infant who suffered from bilateral infranuclear facial nerve palsy (FNP) and multiple coronary artery aneurysms (CAAs) in parallel with KD. The patient had an intermittent fever for 18 days and had a medical history of bilateral conjunctival injection, strawberry tongue, reddened lips, and perianal excoriation. Physical examinations revealed fever (38.5°C), fingertips desquamation of the skin, and left cervical lymphadenopathies.

DIAGNOSIS

The diagnosis of KD is based on the presence of clinical features of persistent fever (≥5 days) together with polymorphous exanthema, cervical lymphadenopathy, non-purulent conjunctival injection, changes of the lips, oral cavity, and extremities. An echocardiogram has showed a beaded sample dilatation of all coronary arteries, in addition to aneurysms of the middle of the right coronary artery (6.2 mm in diameter; 14.5 Z score), and the left coronary artery (5.4 mm in diameter; 9.4 Z score). The physical examinations revealed incomplete closure of both eyes and bilateral drooping of the mouth, suggesting a bilateral infranuclear FNP.

INTERVENTIONS

The patient received intravenous immunoglobulin (IVIG) (2 g/kg) with high-dose aspirin according to the clinical guidelines.

OUTCOMES

Her fever finally resolved after 2 days' IVIG. All inflammatory indexes returned to normal or near-normal levels prior to discharge. However, the echocardiogram remained unchanged and the patient's facial nerve palsies had not recovered.

LESSONS

FNP in KD is uncommon. Yet, it may be a marker of disease progression. One should be aware of the diagnosis of KD when children suffer from high fever, FNP, and even with incomplete clinical features.

Study on the Validity of Surface Electromyography as Assessment Tools for Facial Nerve Palsy

Objectives

The purpose of this study was to find out validity of Surface Electromyography(sEMG) compared with Nerve Conduction Study and clinical assessment scale as assessment factors for facial palsy.

Methods

We investigated 50 cases of patients with peripheral facial palsy who had records of sEMG and NCS to check. Then we analyzed the correlation between sEMG and NCS that carried out around 1 week after onset. And we analyzed the correlation between sEMG and clinical assessment scales that were measured three times around 1 week, 3–4 weeks and 5–6 weeks after onset. Clinical assessment scales used in this study were House-brackmann grade, Yanagihara unweighted grading scale and Sunnybrook facial grading system. We used Pearson’s correlation for statistical analysis.

Results

sEMG and NCS, measured at similar times, were statistically correlated. Especially, the correlation with the forehead region was high. And sEMG and clinical assessment scale, measured at same time, were statistically correlated, especially after 5 weeks from onset.

Conclusion

According to this study, sEMG is expected to be useful to assessment facial palsy.

Intracranial Calcification Masquerading as Hemorrhage in a Patient with Multiple Myeloma Presenting with Facial Neuropathy

Multiple myeloma is an immunoglobulin-producing plasma cell neoplasm that commonly affects the bones, kidneys, the hematopoietic system, and rarely the nervous system. Peripheral nervous system involvement in the form of cranial neuropathy, radiculopathy, and polyneuropathy are common. Compressive myelopathy constitutes the majority of central nervous system disorders followed by cerebrovascular disorders, intracranial plasmacytomas, and leptomeningeal myelomatosis. Cerebrovascular complications such as acute ischemic stroke and transient ischemic attack are not uncommon. Intracerebral hemorrhage, although infrequent, can be secondary to refractory hypertension from renal failure and intratumoral hemorrhage in intracerebral plasmacytomas. Metastatic calcifications in lungs, liver, and skin with high levels of serum calcium and phosphate are seen in patients with multiple myeloma, but intracerebral calcifications are not common. We report an unusual case of intracranial calcification masquerading as acute intracerebral hemorrhage in a patient presenting with acute facial weakness. 

A case of Lyme disease in a Japanese woman

This report presents the case of a Japanese patient who developed Lyme disease. The patient was a 44-year-old woman who had general fatigue and the inability to open her mouth. She was initially suspected of having mild tetanus with lockjaw; however, she reported a past history of a tick bite while camping in the USA and had erythema migrans 2 months before this visit. Finally, Lyme disease was serologically confirmed. A few cases of Lyme disease are annually reported in Japan; however, this infectious disease should also be suspected.

Conservative versus Surgical Therapy in Managing Patients with Facial Nerve Palsy Due to the Temporal Bone Fracture

Facial nerve paralysis is classified into immediate or delayed-onset palsy, and affected patients should be treated through conservative or surgical therapy. Appropriate treatment is somewhat debated as well as proper time for performing surgery. This study aimed to assess treatment outcome between conservatively and surgically treated groups and to determine the appropriate time of surgery in selected patients for surgery. Twenty-four patients from April 2008 to July 2015 were included. Performing decompression surgery within the first 2 months following the trauma accompanies a better prognosis ( p -value < 0.05). Eleven patients were managed conservatively, and 4 of them demonstrated immediate onset and 7 indicated delayed onset. Nine patients obtained normal nerve function, one patient had partial palsy, and one of them had complete palsy. There was no significant difference in the rate of recovery between types of the treatment ( p -value > 0.05). Decompression surgery is recommended in the first 2 months after the trauma for immediate onset and also complete degeneration on electroneuronography.

[Ophthalmic manifestations of facial nerve palsy]

Facial nerve palsy is a common pathology that develops due to various diseases, traumas and medical interventions. The most common peripheral type of facial paralysis leads to acute unilateral involvement of facial muscles along with the development of paralytic lagophthalmos. The absence of adequate and timely medical treatment in patients with paralytic lagophthalmos can lead to severe corneal complications such as cornea perforation causing loss of eye and consequently restricted professional ability, work capacity and significant decrease of patient's life quality. Patients with paralytic lagophthalmos require timely, complex, planned treatment involving various correction methods aimed at protection of the cornea, as well as anatomical and functional recovery of the eyelids. Chemodenervation of the upper eyelid muscles is a pathogenetically substantiated method that can help restore the protective function of the upper eyelid and prevent corneal complications; it can be recommended for early stages of the disease.

Bipolar dissection technique in parotid gland surgery

BACKGROUND

Parotid gland surgery (PGS) has to manage the balancing act between sufficient radicality and preservation of functional structures. While many studies evaluate post-therapeutic complication due to different extent of surgery, the current study introduces bipolar dissection (BP) being a fast and safe preparation technique.

METHODS

Analysis of clinical parameters (age, sex, tumour entity, treatment modalities, facial nerve palsy, bleeding, saliva fistula and Frey's syndrome) of 319 consecutively included patients who underwent extracapsular dissection and superficial/total/radical parotidectomy. Subgroup analysis was done according to the preparation technique (cold vs BP).

RESULTS

Facial nerve palsy rate increased with the extent of PGS (p < .0001). There were no differences in the risk of post-operative bleeding, salivary fistula and Frey's syndrome. BP resulted in a significant reduction of operation time (p = .04), postoperative bleeding (p = .001) and salivary fistula (p = .045) when compared with cold preparation.

CONCLUSIONS

Ubiquitous available BP allows fast and safe PGS regardless its extent.

Three atypical manifestations of granulomatosis with polyangiitis: lateral medullary syndrome, anterior cheek mass and melting scleritis of eye

Granulomatosis with polyangiitis (GPA, formerly Wegener granulomatosis) is a vasculitis with various organ involvement. There have been a few cases of CNS stroke and rare cases of lateral medullary infarction (LMI) as a manifestation of GPA. Also there have been reports of sinuses, nose and laryngeal masses mistakenly referred as carcinomas and subsequently GPA was diagnosed in their pathological reports. Another severe fulminant manifestation can be necrotizing scleritis leading to perforation of sclera. Therefore, here we present some rare and fulminant manifestations of GPA in 3 separate cases for further emphasis of the unusual manifestations of GPA that should always be kept in mind.

Eagle's syndrome with facial palsy

Eagle's syndrome (ES) is a rare disease in which the styloid process is elongated and compressing adjacent structures. We describe a rare presentation of ES in which the patient presented with facial palsy. Facial palsy as a presentation of ES is very rare. A review of the English literature revealed only one previously reported case. Our case is a 39-year-old male who presented with left facial palsy. He also reported a 9-year history of the classical symptoms of ES. A computed tomography scan with three-dimensional reconstruction confirmed the diagnoses. He was started on conservative management but without significant improvement. Surgical intervention was offered, but the patient refused. It is important for otolaryngologists, dentists, and other specialists who deal with head and neck problems to be able to recognize ES despite its rarity. Although the patient responded to a treatment similar to that of Bell's palsy because of the clinical features and imaging, ES was most likely the cause of his facial palsy.

Transient Facial Nerve Palsy After the Scalp Block for Burr Hole Evacuation of Subdural Hematoma

Scalp block has become a frequently used technique with an increasing number of indications today. Despite the many advantages of the scalp block, certain rare complications have been identified. It should be remembered that although it is a relatively safe procedure, it may lead to the development of facial nerve palsy. In this article, we present a case of transient facial nerve palsy developed after the scalp block that was used to drain the subdural hematoma with a burr hole.

Surgical outcome in cystic vestibular schwannomas

Background:

Cystic vestibular schwannomas (VS) form a rare subgroup that differs from the solid variant clinically, radiologically, and histopathologically. These tumors also vary in their surgical outcome and carry a different risk of post-operative complications. We analyzed our series of 64 patients with cystic VS and discuss the technical difficulties related to total excision of these tumors and focus on complication avoidance.

Materials and Methods:

A retrospective review of cystic VS surgically managed over a span of 11 years. The case records were evaluated to record the clinical symptoms and signs, imaging findings, surgical procedure, complications, and follow-up data. Post-operative facial nerve palsy was analyzed with respect to tumor size and tumor type.

Results:

Progressive hearing impairment was the most common initial symptom (76.6%). Atypical initial symptoms were present in 15 patients (23.4%). Preoperatively, 78% patients had good facial nerve function (HB grade 1, 2) and 22% had intermediate (HB grade 3, 4) to poor (HB grade 5 and 6) function. Mean tumor size was 4.1 cm. Complete tumor removal was achieved in 53 patients (83%). The facial nerve was anatomically intact but thinned out after tumor excision in 38 patients (59.4%). Ninety percent patients had either intermediate or poor facial nerve function at follow-up. Poor facial nerve outcome was associated with giant tumors and peripherally located, thin-walled cystic tumors.

Conclusion:

Resection of cystic VS is complicated by peritumoral adhesions of the capsule to the nerve. Extensive manipulation of the nerve in order to dissect the tumor–nerve barrier results in worse facial nerve outcome. The outcome is worse in peripherally located, thin-walled cystic VS as compared to centrally located, thick-walled cystic tumors. Subtotal excision may be justified, especially in tumors with dense adhesion of the cyst wall to the facial nerve in order to preserve nerve integrity.

A smartphone-based automatic diagnosis system for facial nerve palsy

Facial nerve palsy induces a weakness or loss of facial expression through damage of the facial nerve. A quantitative and reliable assessment system for facial nerve palsy is required for both patients and clinicians. In this study, we propose a rapid and portable smartphone-based automatic diagnosis system that discriminates facial nerve palsy from normal subjects. Facial landmarks are localized and tracked by an incremental parallel cascade of the linear regression method. An asymmetry index is computed using the displacement ratio between the left and right side of the forehead and mouth regions during three motions: resting, raising eye-brow and smiling. To classify facial nerve palsy, we used Linear Discriminant Analysis (LDA) and Support Vector Machine (SVM), and Leave-one-out Cross Validation (LOOCV) with 36 subjects. The classification accuracy rate was 88.9%.

Facial nerve paralysis: A case report of rare complication in uncontrolled diabetic patient with mucormycosis

Mucormycosis is a rare opportunistic aggressive and fatal infection caused by mucor fungus. Seven types of mucormycosis are identified based on the extension and involvement of the lesion, of which the rhino orbital mucormycosis is most common in the head and neck region. Although it is widely spread in nature, clinical cases are rare and observed only in immunocompromised patients and patients with uncontrolled diabetes mellitus. Early symptoms include fever, nasal ulceration or necrosis, periorbital edema or facial swelling, paresthesia and reduced vision. Involvement of cranial nerves although not common, facial nerve palsy is a rare finding. The infection may spread through cribriform plate to the brain resulting in extensive cerebellar infarctions. Timely diagnosis and early recognition of the signs and symptoms, correction of underlying medical disorders, and aggressive medical and surgical intervention are necessary for successful therapeutic outcome.

Bell's palsy: a summary of current evidence and referral algorithm

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.

Do oral steroids aid recovery in children with Bell's palsy?

There is growing evidence that steroids are not beneficial for treatment of paediatric patients with Bell's palsy. To investigate, we conducted a retrospective longitudinal study examining notes of 100 children, over 12 years coded for facial nerve palsy. Of the 79 diagnosed with Bell's palsy, all recovered, and for 46 patients we had data on interval from onset of symptoms to resolution (median duration in treated group = 5 weeks, range = 39; median duration in untreated group = 6 weeks, range = 11; P = .86). From our results, we conclude that all children with Bell's palsy recovered, with or without steroid treatment, with no statistically significant difference in symptoms duration. Complications of unresolved Bell's palsy can have important long-term functional and psychosocial consequences. Therefore, we need further research on use of steroids in children with complete/severe cases; it would be a shame to omit treatment due to "absence of evidence" rather than "evidence of absence."

Facial paralysis reconstruction in children and adolescents with central nervous system tumors

Facial paralysis remains a vexing problem in the treatment of posterior cranial fossa tumors in children. Fortunately, current techniques are available to reconstruct the paralyzed face in restoring balance, symmetry, and amelioration of functional sequelae. The restoration of structure and function of the paralyzed face is tantamount to proper social integration and psychosocial rehabilitation. In addition, the facial nerve is important in preventing drying of the eyes, drooling, and speech abnormalities, among other functions. The most visible evidence of facial paralysis is stark asymmetry, especially with animation. This is perhaps the most troubling aspect of facial paralysis and the one that leads to the greatest amount of psychosocial stress for the child and family members. Management strategies include early and late intervention. Early reconstructive goals focus on preservation and strengthening of intact motor end plates through native stimulatory pathways. Late reconstructive efforts are centered on surgically reconstructing permanently lost function based on each third of the face. Use of adjunct modalities such as chemical or surgical denervation and myectomies are also critical tools in restoring symmetry. Physical therapy plays a large role in both early and late facial nerve paralysis in optimizing cosmetic and functional outcome.

Topical rebamipide improves the ocular surface in mild lagophthalmos

Administration of topical rebamipide improves the ocular surface in dry eye. We consecutively studied seven eyes in seven cases (three males and four females) with mild lagophthalmos (three cases after eyelid surgery, two cases of incomplete facial nerve palsy, and two cases of senile ectropion) during the treatment of corneal disorders with rebamipide eye drops four times daily for 2 weeks. The fluorescein corneal staining (FCS) score, tear film break-up time (TBUT), Schirmer’s test, and decimal visual acuity were examined. Ocular symptoms were examined and scored by questioning each patient before and after administration of the drug. In all seven eyes, inferior corneal erosion decreased or disappeared within 2 weeks after administration of topical rebamipide. The FCS score was significantly improved (P < 0.05). The TBUT was significantly extended from 2.9 ± 0.5 seconds to 5.2 ± 0.4 seconds (P < 0.05). The scores of ocular symptoms, such as eye pain, dryness, blurred vision, and foreign body sensations, were significantly improved (P < 0.05).Topical rebamipide was effective for corneal disorders in mild lagophthalmos. This drug may provide a novel approach to treat lagophthalmos.

Facial nerve outcome after vestibular schwannoma surgery: our experience

In this study we evaluate the postoperative facial nerve function after vestibular schwannoma (VS) surgery and analyze the factors that cause it. We included 97 consecutive patients undergoing surgical excision of sporadic unilateral VS. Patient and tumor characteristics, surgical approaches, facial nerve function, extent of tumor removal, perioperative complications are all analyzed through standardized systems. Four different surgical approaches are used: translabyrinthine, retrolabyrinthine, retrosigmoid, and middle cranial fossa. Anatomic preservation of the facial nerve is achieved in 97% of patients. The incidence of postoperative facial palsy is found to be statistically correlated to tumor size, but not to the surgical approach used and to extent of tumor penetration in the internal auditory canal. A significant improvement of the short-term facial nerve outcome is detected in patients undergone simultaneous intraoperative electromyography (EMG) and pneumatic facial nerve monitoring. Complete tumor excision is achieved in 94% of cases. Complication rates are excellent and no deaths are reported. Short- and long-term facial nerve outcome is good and comparable with those of other series reported in literature. In VS surgery both EMG and pneumatic facial nerve monitors should be simultaneously used. Further investigations are desirable to improve the facial outcome respecting the oncological radicality.

Surgical approaches to facial nerve deficits

The facial nerve is one of the most commonly injured cranial nerves. Once injured, the effects on form, function, and psyche are profound. We review the anatomy of the facial nerve from the brain stem to its terminal branches. We also discuss the physical exam findings of facial nerve injury at various levels. Finally, we describe various reconstructive options for reanimating the face and restoring both form and function.

Medium term outcome in Bell's palsy in children

OBJECTIVE

Bell's palsy is a non-life threatening disorder with important functional and psychosocial effects. While recent research has shown significant benefit from treatment with steroids in adults, there have been no conclusive studies demonstrating benefit in children. This study set out to explore the medium term resolution of symptoms in Bell's palsy presenting to the emergency department (ED).

PATIENTS AND METHODS

This was a retrospective cohort study of children attending an Irish paediatric ED with a diagnosis of Bell's palsy. Patients were identified via the ED database. The primary outcome measure was resolution at follow-up call (6-18 months after presentation). Secondary outcome measures were ED treatment, imaging and time to resolution of symptoms.

RESULTS

There were 48 presentations, involving 45 patients. Left and right-sided palsies were equally represented. Of these, 16 (33%) received prednisolone. MRI was performed in five cases (10%), four were normal and one did not change management. In follow-up telephone contact, of 35 presentations, 28 (80%, 95% CI 63% to 91%) had complete resolution, six (17%, 95% CI 7% to 34%) partial resolution to variable degrees and one patient showed no improvement. Of the 13 patients who had received prednisolone, nine (69%, 95% CI 39% to 91%) had complete resolution; of the 22 patients who were not treated with prednisolone 19 (86%, 95% CI 65% to 97%) had complete resolution (p=0.22).

CONCLUSIONS

The majority of children with Bell's palsy have complete resolution of the facial weakness. Steroid use is highly variable and warrants a placebo controlled randomised trial.

Association of Bell's Palsy with Hepatitis E Virus Infection: A Rare Entity

Hepatitis E virus (HEV) infection is a common cause of acute hepatitis in India and other developing countries. The data regarding the neurologic manifestation of HEV infection are limited. The neurologic disorders including Guillain-Barré syndrome, polyradiculopathy, neuralgic amyotrophy, encephalitis, bilateral brachial neuritis, ataxia/proximal myopathy, and acute transverse myelitis have been described. Bell's palsy and other cranial nerve involvement in hepatitis A virus (HAV) and HEV infection are rare. We present the second case of Bell's palsy associated with HEV.

High mega jugular bulb presenting with facial nerve palsy and severe headache

We present a rare case of a 50-year-old female patient with symptomatic high mega jugular bulb requiring surgery. We review her medical file, preoperative and postoperative imaging, audiograms, and surgical report. High jugular bulb was diagnosed with computed tomography and magnetic resonance imaging. Symptoms of facial nerve palsy and headache were abolished after surgical procedure. Headache and facial nerve palsy can be caused by high mega jugular bulb. Surgery is indicated in such symptomatic cases and leads to relief of signs and symptoms of disease.
