RESUMO
The articles regarding needle-embedding treatment for hemifacial spasm published before September 30, 2019 were searched from SinoMed, Wanfang, CNKI, VIP and PubMed database, and were analyzed and summarized from treatment methods, acupoint selection, stage differentiation and action mechanism. As a result, 45 Chinese articles were obtained. The needle-embedding treatment was divided into intradermal needling and acupoint thread-embedding; the top five acupoints were Sibai (ST 2), Taiyang (EX-HN 5), Dicang (ST 4), Jiache (ST 6) and spasm trigger points. The basic research of needle-embedding treatment for hemifacial spasm is weak, and the literature regarding stage differentiation is insufficient, which are in need of further study.

Hemifacial spasm (HS) is a movement disorder characterized by paroxysmal and irregular contractions of the muscles innervated by the facial nerve. Chiari malformation type I (CM I) is a congenital disease characterized by caudal migration of the cerebellar tonsils, and surgical decompression of foramen magnum structures has been used for treatment. The association of HS with CM I is rare, and its pathophysiology and therapeutics are speculative. There are only a few cases reported in the literature concerning this association. The decompression of the posterior fossa for the treatment of CM I has been reported to relieve the symptoms of HS, suggesting a relation between these diseases. However, the possible complications of posterior fossa surgery cannot be underrated. We report the case of a 66-year-old patient, in ambulatory follow-up due to right HS, no longer responding to botulinum toxin treatment. Magnetic resonance imaging (MRI) of the skull revealed compression of the facial nerve and CM I. The patient underwent surgery for HS by neurovascular microdecompression of the facial nerve via right lateral suboccipital craniectomy, but presented significant clinical worsening in the postoperative period even though the cerebellum edema related to surgical manipulation was mild. Due to the clinical worsening, the patient underwent a median suboccipital craniectomy with decompression of the foramenmagnum structures. After this second surgery, the patient had progressive improvement and was discharged from the hospital for ambulatory care.

Introducción: El hemiespasmo facial primario (HFP) se produce por la hiperexcitabilidad del nervio facial y sus núcleos de origen como consecuencia de la compresión vascular. La cirugía de descompresión neurovascular se plantea como alternativa al tratamiento médico refractario. Objetivos: Presentar nuestra experiencia respecto a esta patología. Material y métodos: Se realizó una revisión retrospectiva de pacientes operados por HPF refractarios a tratamiento médico en nuestra institución en los últimos 5 años (periodo 2014-2019). Todos fueron intervenidos vía retrosigmoidea. Se evaluaron datos demográficos, evaluación prequirúrgica y evolución postoperatoria. Resultados: Se operaron 4 pacientes bajo técnica microquirúrgica asistido por endoscopía. Edad promedio 52 años (rango 41-61) con una relación femenino masculino 3:1. El 25% (n=1) presentaba paresia facial grado 2 (HB) en el prequirúrgico. No hubo cambios en cuanto al grado de paresia facial en el postoperatorio en ningún caso. Sólo un paciente registró caída leve en la audiometría postquirúrgica. El 75% (n=3) resolvieron el HFP. Conclusión: Si bien nuestra serie es acotada a un número reducido de pacientes, la cirugía descompresiva microvascular es efectiva como alternativa al tratamiento médico refractario del HFP.
Introduction: Primary hemifacial spasm (PHS) is defined as the hyper excitability of the nerve due to the compression of the facial nerve or its nuclei, most commonly by a vascular structure. The surgical indication for microvascular decompression is resistance to pharmacological treatment or severe adverse effects. Objectives: To present our experience in the surgical treatment of this pathology with this novel technique. Materials and methods: We retrospectively reviewed all patients (n=4) with a diagnosis of PHS, who underwent endoscope-assisted microvascular decompression surgery in our institution during the last 5 years. In all the cases, we choose the retrosigmoid approach. We evaluated demographic data, preoperative evaluation, and post-operative evolution. Results: Endoscope-assisted microvascular decompression was the surgical technique in all the patients. The median age was 52 years, the female-male ratio of 3:1. Only one patient presented a grade 2 facial palsy (House-Brackmann scale) in the preoperative evaluation; there were no significant changes in the post-operative evaluation in any patient. Only one patient experienced worsening in the post-operative audiometric follow-up. The 75% (n=3) of the patients solved the HFP after the surgical treatment. Conclusion: By taking into account our experience in this small case series, we can support the concept that endoscope-assisted microvascular decompression is as effective as the open surgical treatment of the PHS.

Abstract Introduction: The use of surgical decompression of facial hemispasm due to the loop in the internal auditory canal is not always accepted due to the risk related to the surgical procedure. Currently a new surgical technique allows surgeons to work in safer conditions. Objective: To report the results with endoscope-assisted retrosigmoid approach for facial nerve microvascular decompression in hemifacial spasm due to neurovascular conflict. The surgical technique is described. Methods: We carried out a prospective study in a tertiary referral center observing 12 (5 male, 7 female) patients, mean age 57.5 years (range 49-71) affected by hemifacial spasm, that underwent to an endoscope assisted retrosigmoid approach for microvascular decompression. We evaluated intra-operative findings, postoperative HFS resolution and complication rates. Results: Hemifacial spasm resolution was noticed in 9/12 (75%) cases within 24 h after surgery and in 12/12 (100%) subjects within 45 days. A significant (p < 0.001) correlation between preoperative historical duration of hemifacial spasm and postoperative recovery timing was recorded. Only 1 patient had a complication (meningitis), which resolved after intravenous antibiotics with no sequelae. No cases of cerebrospinal fluid leak, facial palsy or hearing impairment were recorded. Hemifacial spasm recurrence was noticed in the only subject where the neurovascular conflict was due to a vein within the internal auditory canal. Conclusions: The endoscope assisted retrosigmoid approach technique offers an optimal visualization of the neurovascular conflict thorough a minimally invasive approach, thus allowing an accurate decompression of the facial nerve with low complication rates. Due to the less invasive nature, the procedure should be considered in functional surgery of the cerebellar pontine angle as hemifacial spasm treatment, specially when the procedure is performed by an otolaryngologist.
Resumo Introdução: O uso de descompressão cirúrgica do espasmo hemifacial devido ao loop no canal auditivo interno nem sempre é aceito devido ao risco relacionado ao procedimento cirúrgico. Atualmente, uma nova técnica cirúrgica permite trabalhar em condições seguras. Objetivo: Relatar os resultados que obtivemos com a abordagem retrosigmóidea assistida por endoscopia para a descompressão microvascular do nervo facial em casos de espasmo hemifacial devido a conflito neurovascular. A técnica cirúrgica é descrita. Método: Realizamos um estudo prospectivo em um centro de referência terciária observando 12 pacientes (5M, 7F), com média de idade de 57,5 (intervalo 49-71) anos com espasmo hemifacial submetidos a uma abordagem retrosigmóide assistida por endoscopia para descompressão microvascular. Foram avaliados os achados intraoperatórios, a resolução pós-operatória do espasmo hemifacial e as taxas de complicações. Resultados: A resolução do espasmo hemifacial foi observada em 9/12 (75%) dos casos nas 24 horas após a cirurgia e em 12/12 (100%) dos indivíduos até 45 dias. Uma correlação significativa (p < 0,001) entre a duração do histórico pré-operatório de espasmo hemifacial e o tempo de recuperação pós-operatório foi registrado. Apenas um paciente apresentou uma complicação (meningite), que foi resolvida após administração de antibióticos por via intravenosa sem sequelas. Nenhum caso fístula liquórica, paralisia facial ou deficiência auditiva foi registrado. A recorrência do espasmo hemifacial foi observada em único indivíduo em quem o conflito neurovascular foi causado por um vaso no interior do canal auditivo interno. Conclusões: A técnica da abordagem retrosigmóidea assistida por endoscopia oferece uma ótima visualização do conflito neurovascular através de uma abordagem minimamente invasiva, permite assim uma descompressão precisa do nervo facial com baixas taxas de complicações. Por ser menos invasivo, o procedimento deve ser considerado na cirurgia funcional do ângulo pontocerebelar como tratamento de espasmo hemifacial, especialmente quando o procedimento é feito por um otorrinolaringologista.

Hemifacial spasm (HFS) is due to the vascular compression of the facial nerve at its root exit zone (REZ). Microvascular decompression (MVD) of the facial nerve near the REZ is an effective treatment for HFS. In MVD for HFS, intraoperative neurophysiological monitoring (INM) has two purposes. The first purpose is to prevent injury to neural structures such as the vestibulocochlear nerve and facial nerve during MVD surgery, which is possible through INM of brainstem auditory evoked potential and facial nerve electromyography (EMG). The second purpose is the unique feature of MVD for HFS, which is to assess and optimize the effectiveness of the vascular decompression. The purpose is achieved mainly through monitoring of abnormal facial nerve EMG that is called as lateral spread response (LSR) and is also partially possible through Z-L response, facial F-wave, and facial motor evoked potentials. Based on the information regarding INM mentioned above, MVD for HFS can be considered as a more safe and effective treatment.

Objective In cases of hemifacial spasm caused by a tortuous vertebrobasilar artery (TVBA), the traditional treatment technique involves Teflon (polytetrafluoroethylene), which can be ineffective and fraught with recurrence and neurological complications. In such cases, there are various techniques of arteriopexy using adhesive compositions, 'suspending loops' made of synthetic materials, dural or fascial flaps, surgical sutures passed around or through the vascular adventitia, as well as fenestrated aneurysmal clips. In the present paper, we describe a new technique of slinging the vertebral artery (VA) to the petrous dura for microvascular decompression (MVD) in a patient with hemifacial spasm caused by a TVBA. Method A 50-year-old taxi driver presented with a left-sided severe hemifacial spasm. A magnetic resonance imaging (MRI) scan of the brain showed a large tortuous left-sided vertebral artery impinging and compressing the exit/entry zone of the 7th and 8th nerve complex. After a craniotomy, a TVBAwas found impinging and compressing the entry zone of the 7th and 8th nerve complex. Arachnoid bands attaching the artery to the nerve complex and the pons were released by sharp microdissection. Through the upper part of the incision, a 2.5 1 cmtemporal fascia free flap was harvested. After the fixation of the free flap, a 60 prolene suture was passed through its length several times using the traditional Bengali sewing and stitching techniques to make embroidered quilts called Nakshi katha. The'prolenated' fascia was passed around the compressing portion of the VA. Both ends of the fascia were brought together and stitched to the posterior petrous dura to keep the TVBA away from the 7th and 8th nerves and the pons. Result The patient had no hemifacial spasm immediately after the recovery from the anesthesia. A postoperative MRI of the brain showed that the VA was away from the entry zone of the 7th and 8th nerves.

ABSTRACT Objective: To determine whether serum levels of anti-acetylcholine receptor antibody (anti-AChR-Abs) are related to clinical parameters of blepharospasm (BSP). Methods: Eighty-three adults with BSP, 60 outpatients with hemifacial spasm (HFS) and 58 controls were recruited. Personal history, demographic factors, response to botulinum toxin type A (BoNT-A) and other neurological conditions were recorded. Anti-AChR-Abs levels were quantified using an enzyme-linked immunosorbent assay. Results: The anti-AChR Abs levels were 0.237 ± 0.022 optical density units in the BSP group, which was significantly different from the HFS group (0.160 ± 0.064) and control group (0.126 ± 0.038). The anti-AChR Abs level was correlated with age and the duration of response to the BoNT-A injection. Conclusion: Patients with BSP had an elevated anti-AChR Abs titer, which suggests that dysimmunity plays a role in the onset of BSP. An increased anti-AChR Abs titer may be a predictor for poor response to BoNT-A in BSP.
RESUMO Objetivo: Determinar se os níveis séricos do anticorpo antirreceptor de acetilcolina (anti-AChR-Abs) estão relacionados aos parâmetros clínicos do blefaroespasmo (BSP). Métodos: Fora recrutados 83 adultos com BSP, 60 pacientes ambulatoriais com espasmo hemifacial (HFS) e 58 controles. Foi aplicado um questionário para registrar história pessoal, fatores demográficos, resposta à toxina botulínica tipo A (BoNT-A) e outras condições neurológicas. Os níveis de anti-AChR-Abs foram quantificados usando um ensaio imunoenzimático. Resultados: O nível de anti-AChR-Abs foi de 0,237 ± 0,022 unidades de densidade óptica (OD) no grupo BSP, significativamente diferente em comparação com o grupo HFS (0,160 ± 0,064) e o grupo controle (0,126 ± 0,038). O nível de anti-AChR-Abs se correlacionou com a idade e a duração da resposta à injeção de BoNT-A. Conclusão: Pacientes com BSP apresentaram títulos elevados de anti-AChR-Abs, o que sugere que a desimunidade desempenha um papel no surgimento de BSP. O aumento do título de anti-AChR-Abs pode ser um preditor de resposta insuficiente à BoNT-A em BSP.

BACKGROUND AND PURPOSE: Hemifacial spasm (HFS) is mostly caused by the compression of the facial nerve by cerebral vessels, but the significance of spasm severity remains unclear. We investigated the clinical significance of spasm severity in patients with HFS who underwent microvascular decompression (MVD). METHODS: We enrolled 636 patients with HFS who underwent MVD between May 2010 and December 2013 at Samsung Medical Center (SMC), Seoul, Korea. Subjects were divided into two groups based on spasm severity: severe (SMC grade 3 or 4) and mild (SMC grade 1 or 2). We compared demographic, clinical, and surgical data between these two groups. RESULTS: The severe-spasm group was older and had a longer disease duration at the time of MVD compared to the mild-spasm group. Additionally, hypertension and diabetes mellitus were more common in the severe-spasm group than in the mild-spasm group. Regarding surgical findings, there were more patients with multiple offending vessels and more-severe indentations in the severe-spasm group than in the mild-spasm group. Even though the surgical outcomes did not differ, the incidence of delayed facial palsy after MVD was higher in the severe-spasm group than in the mild-spasm group. Logistic regression analysis showed that severe-spasm was correlated with longer disease duration, hypertension, severe indentation, multiple offending vessels, and delayed facial palsy after MVD. CONCLUSIONS: Spasm severity does not predict surgical outcomes, but it can be used as a marker of pathologic compression in MVD for HFS, and be considered as a predictor of delayed facial palsy after MVD.

A 19-year-old male patient presented with facial hemi-atrophy with unilateral spasms of the masseter and temporalis muscles. Ultrasound therapy and Transcutaneous Electric Nerve Stimulation therapy, known as combination therapy, were given on alternate days for 2 weeks. At the end of 2 weeks of combination therapy the patient reported a drastic reduction in the number of episodes of muscle spasm. The visual analog scale score for tenderness of the masseter and temporalis was also markedly reduced. No one has previously used combination therapy for the treatment of facial hemi-atrophy with hemi-facial spasms. The encouraging results of the combination therapy has prompted us to document this study.

Vestibular Paroxysmia and facial spasm may be caused by vascular compression of the vestibular and facial root entry zone. We report a case of paroxysmal nystagmus accompanied by facial spasm and which is well visualized by three-dimensional reconstruction images. The 3-dimensional reconstruction image supports the view that vestibular paroxysmia may occur with hemifacial spasm simultaneously due to vascular compression.

Tinnitus had been considered a surgically incurable disease, given the failure of several treatment methods. Jannetta reported that tinnitus is one of the hyperactive diseases of the cranial nerve along with hemifacial spasm and trigeminal neuralgia (TGN). Microvascular decompression (MVD) of the eighth cranial nerve was introduced to treat medically intractable tinnitus. Intraoperative monitoring of brainstem auditory evoked potential (BAEP) was able to reduce postoperative complication rates. Less than 1 ms of latency delay and a 40% decrease in amplitude of wave V of the brainstem evoked potential is a landmark of monitoring during surgery. Less than 6 years of duration of tinnitus, normal BAEP before surgery, no accompanying dizziness before surgery and a loop-type offending artery are effective factors for good surgical results of MVD.

A 61-year-old female presented with 4 years history of left-sided hemifacial spasm. Head MRI and angiography indicated left vertebral artery dissecting aneurysm which compressed ipsilateral cranial nerves Ⅶ and Ⅷ. Microvascular decompression was performed. The dissecting aneurysm was pushed apart and the distal part of the parent artery was adhered to the dura on the petrosum. The compressed nerves were totally decompressed. The symptom of facial spasm was completely resolved immediately after surgery and did not recur during 6 months of follow up.

OBJECTIVE: Microvascular decompression (MVD) for hemifacial spasm (HFS) involving the vertebral artery (VA) can be technically challenging. We investigated the therapeutic effects of a bioglue-coated Teflon sling technique on the VA during MVD in 42 cases. METHODS: A bioglue-coated Teflon sling was crafted by the surgeon and applied to patients in whom neurovascular compression was caused by the VA. The radiologic data, intra-operative findings with detailed introduction of the procedure, and the clinical outcomes of each patient were reviewed and analyzed. RESULTS: The 42 patients included in the analysis consisted of 22 females and 20 males, with an average follow-up duration of 76 months (range 24–132 months). Intraoperative investigation revealed that an artery other than the VA was responsible for the neurovascular compression in all cases : posterior inferior cerebellar artery (PICA) in 23 patients (54.7%) and anterior inferior cerebellar artery (AICA) in 11 patients (26.2%). All patients became symptom-free after MVD. Neither recurrence nor postoperative neurological deficit was noted during the 2-year follow-up, except in one patient who developed permanent deafness. Cerebrospinal fluid (CSF) leak occurred in three patients, and one required dural repair. CONCLUSION: Transposition of the VA using a bioglue-coated Teflon sling is a safe and effective surgical technique for HFS involving the VA. A future prospective study to compare clinical outcomes between groups with and without use of this novel technique is required.

El espasmo Hemifacial (EHF) es un trastorno crónico del movimiento caracterizado por la contracción descontrolada, intermitente y espasmódica o tónica de los músculos de una de las hemicaras. La aplicación de toxina botulínica a través de la quimiodenervación produce parálisis muscular temporal y de forma reversible. Se presenta un caso clínico relacionado con EHF y la aplicación terapéutica de toxina botulínica tipo "A" con buenos resultados.
Hemifacial (EHF) spasm is a chronic movement disorder characterized by uncontrolled, intermittent and spasmodic contraction of the muscles or tone of one of the hemicaras. The application of botulinum toxin through chemodenervation produces temporary muscular paralysis and reversibly. a clinical case involving EHF and the therapeutic application of botulinum toxin type "A" with good results is presented.
