Progress in treatment of facial neuritis by acupuncture combined with medicine from the perspective of modern medicine: A review.

Facial neuritis is a common clinical disease with high incidence, also known as Bell palsy or idiopathic facial nerve paralysis, which is an acute onset of peripheral facial neuropathy. In modern medicine, there have been obstacles to the effective treatment of facial neuritis. At present, the clinical use of Western medicine treatment is also a summary of clinical experience, the reason is that the cause of facial neuritis is unknown. Facial neuritis belongs to the category of "facial paralysis" in traditional Chinese medicine. For thousands of years, Chinese medicine has accumulated a lot of relevant treatment experience in the process of diagnosis and treatment. At the same time, traditional Chinese medicine, acupuncture and the combination of acupuncture and medicine play an important role in the treatment of facial neuritis. This article discusses the treatment of facial neuritis with acupuncture combined with Chinese medicine, based on the research progress of modern medicine. In this review, we provide an overview of the effectiveness of acupuncture and medication combinations and facial neuritis with current studies investigating acupuncture and medication combinations in the treatment of facial neuritis.

Amphiphysin-IgG autoimmune sciatic neuropathy and facial neuropathy related to primary central nervous system lymphoma: A case report.

We reported a 61-year-old man presented with 10-month progressing left sciatic neuropathy and 10-day right facial neuropathy. Serum amphiphysin-IgG was positive. 18F-FDG PET/CT of the whole body showed no signs of malignancy. Treatment with plasma exchange and oral prednisone relieved the symptoms. Nine months later, right hemiparesis and seizure of right limbs developed. 18F-FDG and 18F-PBR06 (18 kDa translocator protein, TSPO) radioligand PET/MRI of the whole body revealed intense uptake in the intracranial lesions. Intracranial lymphoma was diagnosed by stereotactic needle brain biopsy. Mononeuropathies could be paraneoplastic syndromes. TSPO shows high uptake in intracranial lymphoma on 18F-PBR06 PET images.

Psychometric Validation of the FACE-Q Craniofacial Module for Facial Nerve Paralysis.

Background: Systematic reviews have identified the need for a patient-reported outcome measure for facial nerve paralysis (FNP). The aim of this study was to determine the psychometric properties of FACE-Q Craniofacial module scales when used in a combined sample of children and older adults with FNP. Methods: Data were collected between December 2016 and December 2019. We conducted qualitative interviews with children and adults with FNP. FACE-Q data were collected from patients aged 8 years and older with FNP. Rasch measurement theory analysis was used to examine the reliability and validity of the relevant scales in the FNP sample. Results: Twenty-five patients provided 2052 qualitative codes related to appearance, physical, psychological, and social function. Many patient concerns were common across age. The field-test sample included 235 patients aged 8-81 years. Of the 13 scales examined, all 122 items had ordered thresholds and good item fit to the Rasch model. For 12 scales, person separation index values were ≥0.79 and Cronbach's alpha values were ≥0.82. The 13th scale's reliability values were ≥0.71. Conclusion: The FACE-Q Craniofacial module scales described in this study can be used to collect and compare evidence-based outcome data from children and adults with FNP.

Tissue-engineered nerve guides with mesenchymal stem cells in the facial nerve regeneration.

Nerve guides with mesenchymal stem cells have been investigated in the rat facial nerve defect model to promote peripheral nerve regeneration and shorten recovery time to improve patients' quality of life. A 7-mm facial nerve gap experimental rat model is frequently employed in facial nerve regeneration studies. Facial nerve regeneration with nerve guides is evaluated by (1) assessing myelinated fiber counts using toluidine blue staining, (2) immunohistological analysis, (3) determining the g-ratio (axon diameter/total outer diameter) of regenerated nerve on transmission electron microscopic images, (4) retrograde nerve tracing in the facial nucleus, (5) electrophysiological evaluations using compound muscle action potential, and (6) functional evaluations using rat facial palsy scores. Dental pulp and adipose-derived stem cells, easily harvested using a minimally invasive procedure, possess characteristics of mesenchymal tissue lineages and can differentiate into Schwann-like cells. Cultured dental pulp-derived cells can produce neurotrophic factors, including nerve growth factor, brain-derived neurotrophic factor, and glial cell line-derived neurotrophic factor. These neurotrophic factors promote peripheral nerve regeneration and afford protection against facial motor neuron death. Moreover, artificial nerve guides can maneuver axonal regrowth, and dental pulp-derived cells and adipose-derived Schwann cells may supply neurotrophic factors, promoting axonal regeneration. In the present review, the authors discuss facial nerve regeneration using nerve guides with mesenchymal stem cells.

Combination of in-situ collagen injection and rehabilitative treatment in long-lasting facial nerve palsy: a pilot randomized controlled trial.

BACKGROUND: Many rehabilitative attempts have been made to prevent or reduce residual deficits in patients with established and long-term facial palsy (FP). In many clinical settings in-situ injection of collagen-based medical devices have been demonstrated to provide nutritional support for tissues. AIM: To test the effectiveness of a collagen-based treatment for patients complaining of long standing FP, who are following a proprioceptive neuromuscular facilitation protocol (Kabat method) (group A), compared to a FP group only undergoing the Kabat method (group B). DESIGN: Randomised controlled trial. SETTING: Tertiary referral outpatient center and University Hospital. POPULATION: Forty-one patients with a medical diagnosis of long-term unilateral peripheral FP. METHODS: Twenty-one Group A patients were compared, after randomization, to nineteen matched group B patients after 8 weeks of treatment. The outcomes were electromyographic findings, validated questionnaires (Facial Disability Index, FDI and General health-related quality of life assessment, QOL) and clinical grading (House-Brackmann, HB, and synkinesis grading scale). A correlation analysis was performed between pre-/post-treatment differences (Δ) in outcome and clinical-demographic measures. RESULTS: A significant within-subjects improvement, both in electrophysiological and questionnaire scores, was found in both groups. When compared with group B, group A patients exhibited a significant reduction of post-treatment polyphasic potentials of voluntary activity of orbicularis oculi (P=0.017) and oris (P=0.015) and a significant increase in post-treatment duration of voluntary activity of orbicularis oris (P=0.018). Group A subjects demonstrated a significant improvement in questionnaire subscales regarding overall disease perception. Although positive correlations between the ∆FDI and ∆percentage of polyphasic potentials of voluntary activity were found in both groups, negative correlations in group A were found between disease duration and ∆duration of voluntary activity of orbicularis oculi and oris. CONCLUSIONS: The combination of physical rehabilitative procedures with in-situ collagen injections, possibly acting in redirecting the phenomena of reinnervation/reorganization, demonstrated encouraging results in patients affected by long term FP. CLNICAL REHABILITATION IMPACT: In-situ collagen injection could be a safe option enlarging the 'window of opportunity' to improve the voluntary muscle contraction pattern and general and specific disability referred by patients affected by long standing FP.

Deletion of CD38 and supplementation of NAD+ attenuate axon degeneration in a mouse facial nerve axotomy model.

Following facial nerve axotomy, nerve function is not fully restored even after reconstruction. This may be attributed to axon degeneration/neuronal death and sustained neuroinflammation. CD38 is an enzyme that catalyses the hydrolysis of nicotinamide adenine dinucleotide (NAD+) and is a candidate molecule for regulating neurodegeneration and neuroinflammation. In this study, we analyzed the effect of CD38 deletion and NAD+ supplementation on neuronal death and glial activation in the facial nucleus in the brain stem, and on axon degeneration and immune cell infiltration in the distal portion of the facial nerve after axotomy in mice. Compared with wild-type mice, CD38 knockout (KO) mice showed reduced microglial activation in the facial nucleus, whereas the levels of neuronal death were not significantly different. In contrast, the axon degeneration and demyelination were delayed, and macrophage accumulation was reduced in the facial nerve of CD38 KO mice after axotomy. Supplementation of NAD+ with nicotinamide riboside slowed the axon degeneration and demyelination, although it did not alter the level of macrophage infiltration after axotomy. These results suggest that CD38 deletion and supplementation of NAD+ may protect transected axon cell-autonomously after facial nerve axotomy.

Eight-and-a-half syndrome: video evidence and updated literature review.

The eight-and-a-half syndrome (EHS)-defined by the combination of a seventh cranial nerve palsy and an ipsilateral one-and-a-half syndrome-is a rare brainstem syndrome, which localises to the caudal tegmental region of the pons. We present a case of the EHS secondary to an inflammatory lesion on a previously healthy 26-year-old woman, with a literature review emphasising the relevance of aetiological assessment.

[Congenital facial palsy].

Congenital facial palsy is unilateral or bilateral facial nerve palsy at birth due to genetic or different pathogenic factors. It can be divided into syndromic type and non-syndromic type according to its accompanying symptom. The pathogeny and symptom of each type are different, in part with genetic heterogeneity. Congenital facial palsy cannot recover spontaneously. Different types of congenital facial palsy have different treatment schemes. The treatment is significant to the improvement of life quality and physical and mental development of children with congenital facial palsy.

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.

[Clinical observation of interventional opportunity for acupuncture treatment of acute facial neuritis].

OBJECTIVE: To observe the effect of different acupuncture intervention time on the improvement of the symptoms of acute facial neuritis and the length of recovery time, and to find the best interventional opportunity for acute facial neuritis. METHODS: A total of 120 patients with acute facial neuritis (all unilateral onset) were randomly divided into 4 groups, namely group A, group B, group C and group D, 30 cases in each group. Acupuncture performed within 3 days after onset in the group A; oral mecobalamin dispersible tablets and multivitamin B tablets were received within 3 days after onset, and acupuncture was started from the 4th day in the group B; oral mecobalamin dispersible tablets and multivitamin B tablets were given within 5 days after onset, and acupuncture was administered from the 6th day in the group C; oral mecobalamin dispersible tablets and multivitamin B tablets were given within 7 days after onset, and acupuncture was applied from the 8th day in the group D. Penetration needling was the main acupuncture treatment, with infrared radiation on the cheeks, once a day, 6 days a week and 3 weeks were given. After treatment, the symptom scores (Portmann scores) of the 7th, 14th and 28th day after onset were compared. The time of improvement and the clinical effect of each group were compared. RESULTS: On the 7th, 14th and 28th day after onset, the Portmann scores of the 4 groups were higher than those before treatment (all P<0.05). On the 7th, 14th and 28th day after onset, the Portmann scores in the group A were higher than those in the other 3 groups (all P<0.05). There was significant difference between both pairs of group B, group C and group D (all P<0.05). The total effective rate in the group A was 96.7% (29/30), which was higher than 93.3% (28/30), 86.7% (26/30) and 83.3% (25/30) in the other 3 groups (all P<0.05). The difference between the 4 groups in the beginning of improvement, significant improvement time and clinical recovery time was statistically significant (all P<0.05), and the group A was optimal. CONCLUSION: Early intervention of acupuncture with acute facial neuritis can appropriately slow the progression of facial nerve injury, improve the therapeutic effect, and shorten the clinical recovery time.

DEVELOPMENT OF GANGLIONOPATHY AND TABETIC VISCERAL CRISES ON THE BACKGROUND OF POLYRADICULONEUROPATHY ASSOCIATED WITH MONOCLONAL GAMMOPATHY (CASE REPORT).

The article presents an analysis of the clinical occurrence of development of chronic polyradiculoneuropathy associated with monoclonal IgG/k (kappa) gammopathy of the undetermined significance. The peculiarity of this occurrence is the uniqueness of the development of the symptoms which are characteristic of tabes dorsalis in this pathology with episodic severe visceral crises and also with ganglionopathy. The example describes the clinical polymorphism of the course of visceral crises, the problems of their diagnosis and as a consequence of inadequate treatment with the development of severe social maladaptation. The importance of timely diagnosis and treatment of such conditions is discussed.

Facial Myokymia and Hemifacial Spasm in Multiple Sclerosis: A Descriptive Study on Clinical Features and Treatment Outcomes.

OBJECTIVE: Facial Myokymia and hemifacial spasm have been associated with multiple sclerosis; however, their etiology and clinical outcome is uncertain. Here, we describe the clinical, radiologic features, and treatment outcomes of a cohort of patients with multiple sclerosis and history of facial myokymia or hemifacial spasm. METHODOLOGY: We reviewed the clinical features, radiologic features, and treatment outcomes of 35 patients with a diagnosis of multiple sclerosis and facial myokymia (28) or hemifacial spasm (7) seen at Mayo Clinic (Rochester, MN). RESULTS: Facial myokymia was associated with a clinical or radiologic relapse in 11 of 28 patients. In 27 of 28 patients with facial myokymia, symptom resolution occurred within months regardless of treatment. An ipsilateral pontine lesion was found in 3 of 7 cases with hemifacial spasm. Hemifacial spasm was associated with a clinical or radiologic relapse in 3 of 7 cases. Hemifacial spasm resolved within 4 years in 5 of 7 cases, with the remaining cases persisting up to 9 years despite treatment. CONCLUSIONS: Facial myokymia and hemifacial spasm occurring in patients with multiple sclerosis is associated with an ipsilateral pontine MRI lesion in a minority of patients. Facial myokymia is a self-limited process while hemifacial spasm can be persistent in a minority of patients, despite treatment.

[Experimental study of using chitosan nerve conduit combined with PRP to repair facial nerve defect].

Objective:The purpose of this study was to produce chitosan nerve conduit in order to investigate the feasibility of chitosan nerve conduit combined with autologous platelet-rich plasma (PRP) for repairing facial nerve defects.Method:Forty New Zealand white rabbits were randomly divided into four groups (n=10 in each group).Establishment of the facial nerve defect model of the upper buccal branches was placed in the nerve regeneration catheter and injected with the same amount of PRP and saline. The PRP was injected into the chitosan nerve conduit as group A. The physiological saline was injected into the chitosan nerve conduit as group B. The physiological saline was injected into the silicone tube as group C. The PRP was injected into the silicone tube as group D. Eight weeks later,facial nerve gross observation,facial nerve electrophysiological tests,histological observation,image analysis,valuation of nerve regeneration recovery were detected.Result:Five patients were lost to follow up (all five in the modified Semont group),and three patients failed to complete treatment (all three in the Epley group). The sequelae at the 3rd day and one week after modified Semont maneuver were 27 and 9,while 41 and 15 in Epley group. The efficacy rates at the 3rd day and one week after modified Semont maneuver were 91.7% and 98.3%,and 91.9% and 96.8% in Epley group retrospectively. The sequelae and short-term effective rate of patients in modified Semont group was no difference when compared with that in Epley group (P>0.05).Conclusion:The chitosan nerve conduit combined with PRP has a certain effect on the repair of facial nerve defects and is expected to be applied to the repair of clinical facial nerve defects.

A comprehensive assessment considering all differential diagnoses is critical to optimal management, as prompt, appropriate therapy leads to better outcomes.

Facial Nerve Schwannomas: Review of 80 Cases Over 25 Years at Mayo Clinic.

OBJECTIVE: To elucidate the long-term clinical behavior, treatment, and outcomes of sporadic facial nerve schwannoma (FNS) in a large cohort of patients managed in the post-magnetic resonance imaging era. PATIENTS AND METHODS: Retrospective review at a single tertiary health care system (January 1, 1990, through December 31, 2015), evaluating 80 consecutive patients with sporadic FNS. RESULTS: Ninety-eight patients with FNS were identified; 10 with incomplete data and 8 with neurofibromatosis type 2 were excluded. The remaining 80 patients (median age, 47 years; 58% women) were analyzed. Forty-three (54%) patients presented with asymmetrical hearing loss, 33 (41%) reported facial paresis, and 21 (26%) reported facial spasm. Seventeen (21%) exhibited radiologic features mimicking vestibular schwannoma, 14 (18%) presented as a parotid mass, and 5 (6%) were discovered incidentally. Factors predictive of facial nerve paresis or spasm before treatment were female sex and tumor involvement of the labyrinthine/geniculate and tympanic facial nerve segments. The median growth rate among growing FNS was 2.0 mm/y. Details regarding clinical outcome according to treatment modality are described. CONCLUSION: In patients with FNS, female sex and involvement of the labyrinthine/geniculate and tympanic segments of the facial nerve predict a higher probability of facial paresis or spasm. When isolated to the posterior fossa or parotid gland, establishing a preoperative diagnosis of FNS is challenging. Treatment should be tailored according to tumor location and size, existing facial nerve function, patient priorities, and age. A management algorithm is presented, prioritizing long-term facial nerve function.

IgG4-related disease causing facial nerve and optic nerve palsies: Case report and literature review.

IgG4-related disease (IgG4-RD) is increasingly being recognized as an entity effecting the head and neck region. Although most commonly seen with salivary gland or paranasal sinus involvement, IgG4-RD may also involve the temporal bone and skull base. We report a rare care of a 61-year-old female with IgG4-RD presenting as synchronous lesions of the middle ear and middle cranial fossa with polyneuropathy of cranial nerves II, VI, and VII. Initial histopathological evaluation of her resected ear mass suggested a benign inflammatory process but no specific diagnosis. Her symptoms progressed over 10months prompting re-evaluation of the specimen and consideration of the IgG4-RD diagnosis. Key pathologic features included prominent lymphoplasmacytic population, storiform fibrosis, obliterative phlebitis, and IgG4 specific staining. The patient was treated with high-dose intravenous and oral steroids but was transitioned to azathioprine secondary to steroid-induced myopathy. Radiographic studies before and after treatment reveal marked improvement of the intracranial and extracranial disease. Correspondingly, her cranial neuropathies resolved. A high degree of clinical suspicion is necessary to diagnosis IgG4-RD. The diagnosis can be supported by elevated serum IgG, elevated IgG index, and pathognomonic histopathological findings. Primary treatment is with corticosteroids. However, immunotherapy using azathioprine or rituximab can be utilized in recurrent disease or patients with steroid intolerance.

Peripheral Nerve Field Stimulation (PNFS) as a Treatment Option for Intractable Radiation-Induced Facial Neuropathic Pain in a Survivor of Laryngeal Cancer: A Case Report.

BACKGROUND: Treatment-related chronic neuropathic pain represents a major and increasing cause of discomfort in cancer survivors. Unfortunately, in approximately 10%-15% of cases, pain is scarcely relieved by opioids and common painkillers. Thus, alternative measures to manage pain have recently been adopted in these patients. CASE DESCRIPTION: We report the case of a laryngeal cancer survivor who developed an intractable bilateral mandibular radiation-induced neuropathic pain syndrome. His pain was refractory to any pharmacological treatment, whereas the implant of bilateral subcutaneous facial electrodes led to the complete resolution of pain. CONCLUSIONS: To the best of our knowledge, this is the first report in literature describing peripheral nerve field stimulation as a treatment option for intractable cancer treatment-related chronic neuropathic pain. Peripheral nerve field stimulation appears to be a safe and effective procedure.
