Can isolated sudden sensorineural hearing loss (SSNHL) and idiopathic acute facial paralysis (Bell's palsy) be symptoms of COVID-19?

OBJECTIVES: The symptoms of COVID-19 at the time of presentation mainly include fever, cough, respiratory distress and myalgia. On the other hand, as neurological symptoms, disruption of taste and smell and cerebrovascular pathologies are well-known, whereas other neurological symptoms and signs are being newly recognized. Sudden-onset sensorineural hearing loss (SSNHL) and idiopathic acute facial paralysis (Bell's palsy) are otologic emergencies that are frequently encountered by otorhinolaryngology specialists. Although there are many articles describing SSNHL and Bell's palsy in the literature, the literature describing their relationship to COVID-19 is limited. In our study, we aimed to present the neuro-otologic relationship of SSNHL and Bell's palsy with COVID-19. MATERIAL AND METHODS: The pretreatment real-time oronasopharyngeal PCR tests, COVID-19 symptomatology and COVID-19 infection statuses of patients who presented to our clinic with isolated SSNHL and Bell's palsy between April 2020 and April 2021 were questioned, and the data of the patients were collected. Throughout their treatment, the patients were followed-up in terms of COVID-19 infection. This is a prospective study. Moreover, to observe the change in the incidence, the data of patients visiting between January 2019 and January 2020 were also collected. The data of the patients were statistically analyzed using SPSS. RESULTS: The study included a total of 177 patients. The SSNHL group consisted of 91 patients, and the Bell's palsy group consisted of 86 patients. Neither group showed a statistically significant difference in comparison to the year without the pandemic in terms of the patient numbers (incidence), sex, age, morbidity, response to treatment or social habits. There was a statistically significant difference in age only in the Bell's palsy group, but this difference was not medically significant. CONCLUSION: As a result of our study, we did not observe a relationship between COVID-19 and cases of SSNHL and Bell's palsy. It is recommended to apply standard otologic treatment to isolated SSNHL and Bell's palsy patients whose association with COVID-19 is not determined.

Does the SARS-CoV-2 pandemic really increase the frequency of peripheral facial palsy?

PURPOSE: Publications about increased number of peripheral facial paralysis in the COVID-19 pandemic emerged in the literature. However, these studies comprised of an estimate rather than a broad analysis of exact numbers. In this study, we planned to investigate whether the pandemic really resulted in an increase in facial paralysis cases admitted to the hospital by evaluating the cases who applied to our hospital due to facial paralysis in the COVID-19 pandemic year and in the previous 4 years. MATERIALS AND METHODS: Patients who applied to our hospital due to facial paralysis between March 2016-February 2017 (Group 1), between March 2017-February 2018 (Group 2), between March 2018-February 2019 (Group 3), between March 2019-February 2020 (Group 4), and between March 2020-February 2021 (Group 5) were investigated and detailed data were noted. RESULTS: 156, 164, 149, 172 and 157 patients were admitted to the hospital due to peripheral facial paralysis in Group 1, 2, 3, 4, and 5, respectively. Of these patients, 155, 164, 145, 169, and 153 were Bell's palsy, respectively. SARS-CoV-2 RT-PCR test was positive in only 2 of the 153 patients who were diagnosed in the year of the pandemic. CONCLUSIONS: This study showed that the number of peripheral facial paralysis detected during the COVID-19 pandemic was similar to previous years. Very few number of positive SARS-CoV-2 RT-PCR test results may have been found incidentally in Bell's palsy patients. Theses stating that SARS-CoV-2 causes peripheral facial paralysis should be supported by laboratory studies and postmortem research.

A unique association of bifacial weakness, paresthesia and vestibulocochlear neuritis as post-COVID-19 manifestation in pregnant women: a case report.

SARS-CoV-2 is an infection due to a novel virus belonging to the coronavirus family. Since December 2019, first human cases of COVID-19 have been identified in Wuhan (China) and rapidly has been progressed to a global pandemic declared by the world health organization (WHO) on March 11th 2020. The major complication of COVID-19, is pneumonia, but other presentations like cardiovascular and neurological complications have been reported. Herein, we report a first case of pregnant women presented with bifacial weakness and paraesthesia (BFP) associated to a vestibulocochlear neuritis as post-COVID-19 manifestation. This is a 36-year-old Moroccan female patient with a history of SARS-CoV-2 positive 6 weeks before admission. She presented to the emergency department with rapid bifacial paralysis, bilateral lower extremity paresthesia, vertigo, nausea, vomiting and right auricular pain. An acute stroke was ruled out after neurological examination and brain MRI. Clinical presentation, neurophysiological, audiometry and videonystagmography workup additionally to CSF findings were suggestive of a variant of Guillain Barré Syndrome (GBS), which is BFP associated to right vestibulocochlear neuritis. The patient was treated with Intravenous immunoglobulins (IVIG) therapy associated with intravenous steroids. The patient made a complete recovery of the right facial palsy and the sensorineural hearing loss but still have tingling in lower limbs and left facial palsy at 2 weeks´ follow-up. BFP can be induced by COVID-19 as a postinfectious immune-mediated complication. Regarding the pathophysiology of vestibular neuritis, is probably similar to other viral infection causing nerve damage. Clinicians should consider the association of vestibulocochlear neuritis and BFP as a post SARS-CoV-2 manifestation.

Lower motor neuron facial palsy in a postnatal mother with COVID-19.

COVID-19 is caused by the novel SARS-CoV-2 and is a potentially fatal disease that is of great global public health concern. In addition to respiratory symptoms, neurological manifestations have been associated with COVID-19. This is attributed to the neurotropic nature of coronaviruses. The authors present a case of Bell's palsy associated with COVID-19 in a term primigravida.

Facial paralysis as the only symptom of COVID-19: A prospective study.

PURPOSE: Idiopathic facial palsy is called as Bell's palsy and reports showed that facial paralysis increased during COVID-19 pandemic period. There are many reports about the relationship between COVID-19 and facial paralysis but there is no prospective study. SARS-CoV-2 IgG and IgM antibodies increase in COVID-19. Our purpose is to investigate SARS-CoV-2 IgG + IgM antibody in the Bell's palsy. METHODS: Prospective cross-sectional study was planned. Patients with acute peripheral facial paralysis with no reason and diagnosed as Bell's palsy was included in the study. In order to investigate SARS-CoV-2 in the etiologies of these patients, SARS-CoV-2 IgM + IgG (total) test was studied. SARS-CoV-2 IgG + IgM was measured by using the ADVIA Centaur® test kit. Test reports result in index values and as nonreactive or reactive. The results were analyzed. RESULTS: Forty-one patients were included in the study. The average age of the patients was 41,7. 17 (41,4%) were female and 24 (58,6%) were male. 21 patients had left-sided; 20 had right-sided paralysis. SARS-CoV-2 IgG + IgM values were measured two times of the patients. First control was in the first week of facial paralysis, 10 (24,3%) positivity was found. The average index of the positive patients were 6,74 (min.1,39-max.10) in the first control and 9,585 in the second control (min.8,7-max. 10). CONCLUSION: We found that the SARS-CoV-2 IgM + IgG antibody test was positive in 24.3% of the patients with Bell's palsy. The results are higher than the seroprevalence studies conducted in asymptomatic individuals. Facial paralysis could be the only symptom of COVID-19 but further studies must be done.

Clinical neurophysiology and cerebrospinal liquor analysis to detect Guillain-Barré syndrome and polyneuritis cranialis in COVID-19 patients: A case series.

We report a case series of five patients affected by SARS-CoV-2 who developed neurological symptoms, mainly expressing as polyradiculoneuritis and cranial polyneuritis in the 2 months of COVID-19 pandemic in a city in the northeast of Italy. A diagnosis of Guillain-Barré syndrome was made on the basis of clinical presentation, cerebrospinal fluid analysis, and electroneurography. In four of them, the therapeutic approach included the administration of intravenous immunoglobulin (0.4 g/kg for 5 days), which resulted in the improvement of neurological symptoms. Clinical neurophysiology revealed the presence of conduction block, absence of F waves, and in two cases a significant decrease in amplitude of compound motor action potential compound muscle action potential (cMAP). Four patients presented a mild facial nerve involvement limited to the muscles of the lower face, with sparing of the forehead muscles associated to ageusia. In one patient, taste assessment showed right-sided ageusia of the tongue, ipsilateral to the mild facial palsy. In three patients we observed albuminocytological dissociation in the cerebrospinal fluid, and notably, we found an increase of inflammatory mediators such as the interleukin-8. Peripheral nervous system involvement after infection with COVID-19 is possible and may include several signs that may be successfully treated with immunoglobulin therapy.

Síndrome de Ramsay Hunt: revisión narrativa / Ramsay Hunt Syndrome: Narrative Review

El síndrome de Ramsay Hunt (SRH) corresponde a la asociación de la parálisis facial periférica con una erupción vesicular localizada en el pabellón auricular, causada por el compromiso del ganglio geniculado secundario a una infección por el virus de la varicela-zóster (VVZ). Este síndrome es la segunda causa más común de parálisis facial atraumática y representa aproximadamente el 10 %-12 % de las parálisis faciales agudas, con una incidencia anual de 5 por cada 100 000 habitantes en Estados Unidos. El diagnóstico es principalmente clínico y entre las manifestaciones más destacadas se encuentran síntomas neurológicos como otalgia, tinnitus, hipoacusia asociada con parálisis facial junto a lesiones herpéticas características. Dentro de las complicaciones que se pueden presentar en esta entidad se encuentra, principalmente, la neuralgia posherpética, seguida de otras menos frecuentes como la encefalitis, el herpes zóster oftálmico y la mielitis. El manejo actual del SRH se basa en la aplicación de terapias duales con corticosteroides asociados a terapia antiviral, lo cual ha demostrado que el inicio temprano del tratamiento mejora el pronóstico y disminuye la aparición de complicaciones. El pronóstico de esta patología es inferior en comparación a patologías menos severas que comprometen el nervio facial (como la parálisis de Bell) y se ve impactado por varios factores como el inicio oportuno de tratamiento, el grupo etario y la presencia de comorbilidades.

Ramsay Hunt syndrome corresponds to the association of peripheral facial paralysis with a vesicular eruption located in the pinna, caused by the involvement of the geniculate ganglion secondary to infection by the varicella zoster virus. This syndrome is the second causes of atraumatic facial paralysis, representing approximately 10 %-12 % of acute facial paralysis, with an annual incidence of 5 per 100,000 inhabitants. The diagnosis is mainly clinical and among the most prominent manifestations are neurological symptoms such as otalgia, tinnitus, hypoacusis associated with facial paralysis together with characteristic herpetic lesions. Among the complications that may occur in this entity is mainly postherpetic neuralgia, followed by less frequent ones such as encephalitis, ophthalmic herpes zoster and myelitis. Current management of Ramsay Hunt syndrome is based on the application of dual therapies consisting of corticosteroids associated with antiviral therapy, showing that early initiation of treatment improves prognosis and reduces the appearance of complications. The prognosis of this pathology is inferior compared to less severe pathologies that compromise the facial nerve (Bell's palsy) and is impacted by several factors such as the timely initiation of treatment, the age group, and the presence of comorbidities.

Peripheral facial nerve palsy associated with COVID-19.

COVID-19 pandemic revealed several neurological syndromes related to this infection. We describe the clinical, laboratory, and radiological features of eight patients with COVID-19 who developed peripheral facial palsy during infection. In three patients, facial palsy was the first symptom. Nerve damage resulted in mild dysfunction in five patients and moderate in three. SARS-Cov-2 was not detected in CSF by PCR in any of the samples. Seven out of eight patients were treated with steroids and all patients have complete or partial recovery of the symptoms. Peripheral facial palsy should be added to the spectrum of neurological manifestations associated with COVID-19.

Peripheral Facial Nerve Palsy in Children With Enterovirus Infection.

Enteroviruses are one of the leading causes of central nervous system infections, but their causative role in peripheral facial nerve palsy is unresolved. We used data from a large national Enterovirus Surveillance Database to identify cases of facial nerve palsy, showing a rate of 3.8% of patients with facial nerve palsy to have enterovirus infection.

Bilateral asymmetrical herpes-zoster with Ramsay hunt syndrome in an immunocompetent adult.

BACKGROUND: Bilateral herpes zoster (BHZ) is an atypical presentation of herpes zoster (HZ), with few cases reported before. Ramsay Hunt syndrome (RHS) is an uncommon complication of VZV infection. Cases of BHZ with RHS in immunocompetent adults have been reported rarely. CASE PRESENTATION: We described an immunocompetent adult who suffered from left-sided thoracic herpes zoster and contralateral RHS simultaneously, and summarizes the characteristics of BHZ. CONCLUSIONS: Cases of BHZ with RHS in immunocompetent adults have not been reported previously. Antivirus - glucocorticoid combination therapy showed a good effect in this case.

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.

CXCL13 in patients with facial palsy caused by varicella zoster virus and Borrelia burgdorferi: a comparative study.

High cerebrospinal fluid (CSF) concentrations of the chemokine CXCL13 have been associated with Lyme neuroborreliosis (LNB), and have recently been studied as a potential diagnostic marker. It has proven difficult to establish a reliable diagnostic cut-off, possibly in part due to heterogenicity of case-control groups. Our purpose was to investigate CSF CXCL13 concentrations in patients with similar clinical presentations, facial palsy. We retrospectively included patients with facial palsy associated with LNB (n = 21), or varicella zoster virus (VZV) (n = 26). Median CXCL13 concentrations were significantly higher in patients with LNB facial palsy compared to VZV facial palsy. Receiver-operating characteristic analyses yielded an optimal cut-off concentration at 34.5 pg/mL (sensitivity 85.7%, specificity of 84.6%), lower than that in previous studies. Although the analysis has potential, it is still not adequately established that CXCL13 provides additional, clinically useful, diagnostic information over current recommendations.

Facial diplegia, a possible atypical variant of Guillain-Barré Syndrome as a rare neurological complication of SARS-CoV-2.

We present a case of facial diplegia after 10 days of SARS-CoV-2 confirmed infection symptoms in a 61 year old patient without prior clinically relevant background. There are few known cases of Guillain-Barré Syndrome (GBS) related to SARS-CoV-2 infection; we propose this case as a rare variant of GBS in COVID-19 infection context, due to Its chronology, clinical manifestations and cerebrospinal fluid (CSF) findings.

Multiple cranial nerve injury in Ramsay Hunt Syndrome: a case report.

Herpes zoster oticus (Ramsay Hunt Syndrome) is characterized by facial nerve paralysis, ear pain and auricular skin rash. It occurs as a result of reactivation oflatent varicella zoster virus infection in the geniculate ganglion of the facial nerve. Major clinical symptoms include 7th nerve paralysis or cranial nerve paralysis and vesicles along the nerve with cocomitant ear pain. Other cranial nerve involvement although uncommon, can be found in some cases. In this study, a 74-year-old female patient had ipsilateral 8th, 9th and 10th cranial nerves injury. Cranial nerve paralysis accompanied with injury has been repor ted in R amsay Hunt Syndrome.

Etiology and therapy of delayed facial paralysis after middle ear surgery.

PURPOSE: This review focuses on the etiology, incidence and therapy of delayed paralysis of the facial nerve (DFP) after different types of middle ear surgery. METHODS: Retrospective review of studies published in English from 1970 until 2019 reporting DFP after tympanoplasty, tympanomastoid surgery, stapedotomy and stapedectomy. The search used the databases of PubMed, Scopus and Cochrane Library. Studies reporting from adult patients and DFP onset after 48 h after surgery were included. Studies dealing with iatrogenic or preexisting facial palsy and case reports were excluded. The initial literature search resulted in 52 studies. The relevance of the publications was verified using title, abstract and full-text analysis. Data were analyzed with descriptive statistics using median, simple sum and statistical significance. RESULTS: Ten studies having 12,161 patients could be included in this review. The incidence of DFP after the middle ear surgeries varies between 0.2 and 1.9%. The surgical stress of the middle ear surgeries is the main trigger for the development of DFP and leads to a virus reactivation and/or neuronal edema. Patients with a dehiscence of the facial canal have a significantly higher probability for a DFP. The recommended therapy of DFP based on the data of the therapy of Bell's palsy, consists of the administration of a steroid. For patients having a case history of previous viral infections, an antiviral prophylaxis is recommended. CONCLUSION: Overall, DFP has a very good prognosis, with mostly complete healing with appropriate therapy. Viral reactivation is the most favored genesis of DFP. Immunization or antiviral prophylaxis is recommended to those patients being at risk for a viral reactivation.
