Should acupuncture therapy be used for acute facial paralysis? A protocol for systematic review.

BACKGROUND: Peripheral facial paralysis (PFP) results in functional disorder and social dysfunction, when it is under a severe condition at onset, long-term poor outcomes do occur. Different acupuncture methods have been reported to be potentially effective for shortening the disease course and reducing the occurrence of sequelae when they are applied at an early stage. Neuro edema is a common pathological feature in the acute phase, and many clinical studies have suggested its effect of reducing facial nerve edema. It is of value to estimate the effectiveness and safety of acupuncture treatment at the onset, and to assess the most suitable acupuncture method for the acute period. METHODS AND ANALYSIS: All the RCTs and quasi-RCTs on acupuncture therapy for patients who is during acute stage of PFP will be included. The recovery rate of facial function, the time it takes to restore facial function and the odds of sequelae occurring will be the key parts we focus on. Psychological well-being and quality of life will also be evaluated. Literature searching will be conducted until December 31th, 2022 from eight databases systematically. Two reviewers will screen the literature and extract the data independently. RevMan software will be used for data analysis, and the version 2 of the Cochrane risk-of-bias tool (RoB 2) will be used to assess the certainty of evidence. Forest plots and summary findings will be generated. If data permits, a meta-analysis will be conducted. ETHICS AND DISSEMINATION: Since this study will not involve clinical treatment of patients, ethics approval is not required. The result of this study will be submitted to a peer-reviewed journal for publication and as a proposal for clinical practice and further study on acupuncture treatment at the early stage of PFP. DISCUSSION: This review will summarize the evidence on the different type of acupuncture therapy for acute Bell's palsy and Ramsay-Hunt syndrome. We anticipate that it would be safe and effective when applied to the acute phase of PFP, and some specific suitable acupuncture methods would be found resulting from this review.

Clinical spectrum and prognosis of neurological complications of reactivated varicella-zoster infection: the role of immunosuppression.

Immunosuppressed patients are at higher risk for developing herpes zoster (HZ), and neurological complications are frequent in them. However, the influence of immunosuppression (IS) on the severity and prognosis of neurological complications of varicella-zoster virus (VZV) reactivation is unknown. We studied retrospectively patients with neurological complications due to VZV reactivation who attended our hospital between 2004 and 2019. We aimed to assess the clinical spectrum, potential prognostic factors, and the influence of the immune status on the severity of neurological symptoms. A total of 98 patients were included (40% had IS). Fifty-five patients (56%) had cranial neuropathies which included Ramsay-Hunt syndrome (36 patients) and cranial multineuritis (23 patients). Twenty-one patients developed encephalitis (21%). Other diagnosis included radiculopathies, meningitis, vasculitis, or myelitis (15, 10, 6, and 4 patients, respectively). Mortality was low (3%). At follow-up, 24% of patients had persistent symptoms although these were usually mild. IS was associated with severity (defined as a modified Rankin scale greater than 2) (odds ratio, 4.23; 95% confidence interval, 1.74-10.27), but not with prognosis. Shorter latency between HZ and neurologic symptoms was the only factor associated with an unfavorable course (death or sequelae) (odds ratio, 0.82; 95% confidence interval, 0.71-0.95). In conclusion, the clinical spectrum of neurological complications in VZV reactivation is wide. Mortality was low and sequelae were mild. The presence of IS may play a role on the severity of neurological symptoms, and a shorter time between HZ and the onset of neurological symptoms appears to be a negative prognostic factor.

Ramsay Hunt syndrome with pontine lesion: A case report.

RATIONALE: The coexistence of Ramsay Hunt syndrome (RHS) and varicella-zoster virus (VZV) encephalitis is rare. A patient who developed RHS after being infected with VZV, along with a pontine lesion, is reported in the present study. PATIENT CONCERNS: A 41-year-old male patient presented with his mouth askew for 7 days, and dizziness, accompanied by hearing loss for 3 days. DIAGNOSES: The patient was initially diagnosed with RHS. Brainstem encephalitis was confirmed by lumbar puncture and cerebrospinal fluid. Brain magnetic resonance imaging (MRI) and diffusion-weighted imaging (DWI) revealed how VZV entered the intracranial space along the vestibulocochlear nerve and facial nerve in the acute period. INTERVENTIONS: Intravenous acyclovir, IV, immunoglobulins (IVIg) and methylprednisolone were administered. OUTCOMES: The herpes was cleared up and left facial nerve palsy was improved, but hearing loss in the left ear did not improve. LESSONS: An MRI was necessary for some VZV infections limited to the cranial nerve, although there was no evidence of brain stem injury. DWI provided evidence, showing how VZV entered the brain in the early stage. This allowed the doctor to judge the necessity of a lumbar puncture.

Typical or Atypical Ramsay-Hunt Syndrome in Delayed Facial Palsy After Stapedectomy?

OBJECTIVES: The aim of this study was to define the typical pattern for varicella zoster virus (VZV) reactivation in delayed facial palsy (DFP) after stapedectomy for otosclerosis. MATERIALS AND METHODS: Review of the relevant literature, personal casistics, and case-report. RESULTS: In total, 48 cases of DFP after stapes surgery have been described so far, including the reported case with exclusive manifestation of atypical Ramsay Hunt syndrome (RH); in the personal series of 1253 stapedectomies, DFP occurred in only one case (0.08%). Complete DFP (House-Brackmann grade VI) rapidly developed 12 days after surgery; RH appeared 2 days later, confirming the role of VZV. The DFP started improving after 8 weeks and completely recovered 6 months later. CONCLUSION: Acute otalgia prior to DFP should raise the suspicion of VZV reactivation. Atypical RH is the most frequent pattern that occurs in DFP after stapedectomy.

Facial palsy after dental procedures - Is viral reactivation responsible?

OBJECTIVES: Herpes labialis viral reactivation has been reported following dental procedures, but the incidence, characteristics and outcomes of delayed peripheral facial nerve palsy following dental work is poorly understood. Herein we describe the unique features of delayed facial paresis following dental procedures. MATERIALS AND METHODS: An institutional retrospective review was performed to identify patients diagnosed with delayed facial nerve palsy within 30 days of dental manipulation. Demographics, prodromal signs and symptoms, initial medical treatment and outcomes were assessed. RESULTS: Of 2471 patients with facial palsy, 16 (0.7%) had delayed facial paresis following ipsilateral dental procedures. Average age at presentation was 44 yrs and 56% (9/16) were female. Clinical evaluation was consistent with Bell's palsy in 14 (88%) and Ramsay-Hunt syndrome in 2 patients (12%). Patients developed facial paresis an average of 3.9 days after the dental procedure, with all individuals developing a flaccid paralysis (House Brackmann (HB) grade VI) during the acute stage. 50% of patients developed persistent facial palsy in the form of non-flaccid facial paralysis (HBIII-IV). CONCLUSION: Facial palsy, like herpes labialis, can occur in the days following dental procedures and may also be related to viral reactivation. In this small cohort, long-term facial outcomes appear worse than for spontaneous Bell's palsy.

Herpes zoster on the face in the elderly.

Herpes zoster is a localised disease caused by reactivation of the varicella zoster virus that enters the cutaneous nerve endings during an earlier episode of chicken pox, travels to the dorsal root ganglia, and remains in latent form. The condition is characterised by occurrence of multiple, painful, unilateral vesicles and ulceration, and shows a typical single dermatome innervated by single dorsal root or cranial sensory ganglion. Involvement of three or more dermatomes is known as disseminated zoster and seen in immunocompromised individuals. Complications of herpes zoster include ocular sequelae, bacterial superinfection of the lesions, meningoencephalitis and postherpetic neuralgia. The incidence of herpes zoster increases with age and immunosuppression, therefore prompt management is necessary to avoid morbidity and mortality in these individuals. We present two case reports of herpes zoster, one involving the maxillary and mandibular branches of the trigeminal nerve while the other involves all branches of the trigeminal nerve.

Ramsay Hunt syndrome with facial vesicular rash: a unique clinical presentation in a kidney transplant patient.

Ramsay Hunt Syndrome (RHS) is the result of herpes zoster virus reactivation producing hearing loss, pain and vesicles in the ear or mouth, along with ipsilateral facial palsy due to the 7th cranial nerve geniculate ganglion infectious involvement. This condition has not been previously described, particularly in transplant patients. A 38-year old man underwent kidney transplantation and two years later experienced an ache on the left side of the face and hearing loss in the ear, also exhibiting vesicular lesions and concomitant facial peripheral palsy. Acyclovir IV was initiated, and the prednisone dose was increased. The patient was discharged 15 days later, feeling better but still exhibiting dark spots on his face. At three months follow-up he was asymptomatic, showing notable palsy improvement. Until this case, herpes zoster facial lesions causing typical RHS have never been reported in literature, particularly in kidney transplant patients.

Geniculate neuralgia: a systematic review.

OBJECTIVE: To systematically summarise the peer-reviewed literature relating to the aetiology, clinical presentation, investigation and treatment of geniculate neuralgia. DATA SOURCES: Articles published in English between 1932 and 2012, identified using Medline, Embase and Cochrane databases. METHODS: The search terms 'geniculate neuralgia', 'nervus intermedius neuralgia', 'facial pain', 'otalgia' and 'neuralgia' were used to identify relevant papers. RESULTS: Fewer than 150 reported cases were published in English between 1932 and 2012. The aetiology of the condition remains unknown, and clinical presentation varies. Non-neuralgic causes of otalgia should always be excluded by a thorough clinical examination, audiological assessment and radiological investigations before making a diagnosis of geniculate neuralgia. Conservative medical treatment is always the first-line therapy. Surgical treatment should be offered if medical treatment fails. The two commonest surgical options are transection of the nervus intermedius, and microvascular decompression of the nerve at the nerve root entry zone of the brainstem. However, extracranial intratemporal division of the cutaneous branches of the facial nerve may offer a safer and similarly effective treatment. CONCLUSION: The response to medical treatment for this condition varies between individuals. The long-term outcomes of surgery remain unknown because of limited data.

Ramsay Hunt syndrome with multiple cranial neuropathies in a liver transplant recipient.

Ramsay Hunt syndrome is an infection of the head and neck caused by varicella zoster virus involving the facial nerve; less commonly, other cranial nerves might be involved. We report a case of Ramsay Hunt syndrome in an immune compromised patient, with classic facial nerve palsy and ipsilateral ear vesicles, which rapidly evolved to involve multiple cranial neuropathies, and improved dramatically with antiviral therapy and corticosteroids. Varicella zoster virus should be considered as a cause of multiple cranial neuropathies in an immune compromised patient, and abrupt treatment with acyclovir should be initiated once this diagnosis is suspected.

[Case of atypical Ramsay-Hunt syndrome who presented with severe vertigo and vomiting].

We herein present a case of 6-year-old female demonstrating atypical Ramsay-Hunt syndrome. She presented with an earache, severe vertigo, and vomiting at onset, and thereafter, herpes zoster oticus appeared. No facial nerve palsy was seen. She was vaccinated for varicella and had no past history of apparent varicella infection. The patient showed positive IgG and negative IgM serum antibodies for varicella-zoster virus (VZV). An analysis of VZV-DNA from the patient's ear lesion using alleric discrimination real-time PCR identified a wild-type strain of VZV. We diagnosed her to have atypical Ramsay-Hunt syndrome caused by reactivation of the VZV. Aciclovir and prednisolone were administered, and she recovered completely. This case indicates that Ramsay-Hunt syndrome could be caused by a VZV infection after vaccination, even though its frequency is low. Ramsay-Hunt syndrome may thus be considered as one of causes of sudden onset vertigo in children.
