Purpose: To evaluate the effect of hemifacial spasm (HFS) on intraocular pressure (IOP) measurement. Methods: Twenty-four consecutive patients with HFS and 25 age- and gender-matched randomly selected eyes of healthy volunteers underwent corneal pachymetry and IOP measurements using Goldmann applanation tonometer (GAT) and noncontact tonometer (NCT). IOP measurements were performed before (during HFS) and 2 weeks after Botox injections in HFS patients and in healthy volunteers without Botox injections...

INTRODUCTION: Facial nerve schwannomas are rare tumors and account for less than 2% of intracranial neurinomas, despite being the most common tumors of the facial nerve. The optimal management is currently under debate and includes observation, microsurgical resection, radiosurgery (RS), and fractionated radiotherapy. Radiosurgery might be a valuable alternative, as a minimally invasive technique, in symptomatic patients and/or presenting tumor growth. METHODS: We review our series of four consecutive cases, treated with Gamma Knife surgery (GKS) between July 2010 and July 2017 in Lausanne University Hospital, Switzerland...

Botulinum neurotoxins (BoNTs) are now among the most widely used therapeutic agents in clinical medicine with indications applied to the fields of movement disorders, pain disorders, and autonomic dysfunction. In this literature review, the efficacy and utility of BoNTs in the field of movement disorders are assessed using the criteria of the Guideline Development Subcommittee of the American Academy of Neurology. The literature supports a level A efficacy (established) for BoNT therapy in cervical dystonia and a level B efficacy (probably effective) for blepharospasm, hemifacial spasm, laryngeal dystonia (spasmodic dysphonia), task-specific dystonias, essential tremor, and Parkinson rest tremor...

Over the last decades microvascular decompression (MVD) has been established as the curative treatment of the primary Hemifacial Spasm (HFS), proven to be linked in almost all cases to a neurovascular compression of the facial nerve. Because the disease is not life-threatening and MVD not totally innocuous, efficacy and safety have to be weighted before decision taken of indicating surgery. The authors have been charged by the French Speaking Society of Neurosurgery to conduct a detailed evaluation of the probability of relief of the spasm that MVD is able to obtain, together with its potential complications...

BACKGROUND: While high-resolution imaging is increasingly used in guiding decisions about surgical interventions for the treatment of trigeminal neuralgia, direct assessment of the extent of vascular contact of the trigeminal nerve is still considered the gold standard for the determination of whether nerve decompression is warranted. OBJECTIVE: To compare intraoperative and magnetic resonance imaging (MRI) findings of the prevalence and severity of vascular compression of the trigeminal nerve in patients without classical trigeminal neuralgia...

BACKGROUND: Few previous studies have described the origin of both anterior and posterior inferior cerebellar arteries from one vessel as a common trunk anomaly. No previous studies have clearly described the aforementioned anomaly depending on intraoperative endoscopic visualization. OBJECTIVE: To evaluate the association of a common trunk anomaly with hemifacial spasm, which makes microvascular decompression more challenging. METHODS: All patients with common trunk anomaly associated with hemifacial spasm who received surgical treatment between 2006 and 2015 in our institution were identified in our prospectively collected database...

BACKGROUND: Z-L response (ZLR) has been suggested to a new electromyographic (EMG) potential recorded from the facial muscle of patient with hemifacial spasm (HFS) during microvascular decompression (MVD). Although ZLR has been suggested to be useful, experience of ZLR monitoring is limited and its significance during MVD is still unclear. METHODS: To investigate the significance of ZLR, both ZLR and abnormal muscle response (AMR) were simultaneously recorded before and after decompression of root exit zone (REZ) in 20 consecutive patients with HFS...

OBJECTIVE: The aim of this study was to define the critical warning sign of real-time brainstem auditory evoked potential (BAEP) for predicting hearing loss (HL) after microvascular decompression (MVD) for hemifacial spasm (HFS). METHODS: Nine hundred and thirty-two patients with HFS who underwent MVD with intraoperative monitoring (IOM) of BAEP were analyzed. We used a 43.9 Hz/s stimulation rate and 400 averaging trials to obtain BAEP. To evaluate HL, pure-tone audiometry and speech discrimination scoring were performed before and one week after surgery...

Objective: To validate the usefulness of the supine position in microsurgery for lesions of the cerebellopontine angle (CPA) by the retrosigmoid approach. Methods: Thirty-nine patients with lesions (22 cases of tumor, 11 cases of trigeminal neuralgia and 6 cases of hemifacial spasm) of the CPA underwent tumor resection surgery or microvascular decompression surgery (MVDS). The patients were operated on in the supine position by retrosigmoid approach with the head turned 50 to 60 degrees away from the lesion and with slight forward flexion of the neck...

OBJECTIVE: Although repeat microvascular decompression (MVD) for hemifacial spasm (HFS) in patients with failed prior MVD is potentially curative, little is known about the long-term results of repeat MVD. We aimed to evaluate the long-term outcomes and complications after repeat MVD for HFS. METHODS: We performed repeat MVD on 78 consecutive patients who had undergone a prior MVD >1 year previously. Follow-up data were available for 58 patients, with a median follow-up period of 8...

BACKGROUND: Although microvascular decompression (MVD) has been widely accepted as an effective treatment for hemifacial spasm (HFS), some patients may experience delayed relief instead of immediate improvement after the surgery. The need for and timing of repeat MVD has been controversial to date; thus, we conducted the present study with emphasis on those unrelieved patients. METHODS: Between January 2010 and December 2014, 3095 patients with idiopathic HFS were treated with MVD at XinHua Hospital, Shanghai Jiaotong University School of Medicine...

Background: Microvascular decompression (MVD) is the preferred treatment for refractory trigeminal neuralgia, hemifacial spasm, and glossopharyngeal neuralgia. Despite its high rate of success, MVD carries risk of complications. In this study, we examine outcomes following MVD and identify risk factors associated with adverse outcomes. Methods: A review of the American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) database was performed with CPT code 61458 queried between 2007 and 2014...

Background: Intracranial epidermoid tumors are commonly found in the cerebellopontine angle where they usually present with either trigeminal neuralgia or hemifacial spasm. Radiosurgery for these tumors has rarely been reported. The purpose of this study is to assess the safety and clinical outcome of the treatment of cerebellopontine epidermoid tumors with gamma knife radiosurgery. Methods: This is a retrospective study involving 12 patients harboring cerebellopontine angle epidermoid tumors who underwent 15 sessions of gamma knife radiosurgery...

BACKGROUND: Microvascular decompression (MVD) is useful treatment for hemifacial spasm (HFS) with refractory hypertension (RHTN). The biomedical glue sling technique is a new method for MVD. In this study, we retrospectively compared the outcome of the biomedical glue sling technique with traditional technique in MVD for HFS with RHTN. METHODS: A retrospective study of HFS with RHTN treated by MVD was conducted between January 2010 and June 2016. Among 155 patients who underwent their first MVD at our institution, traditional technique was performed in 73 cases of patients and the biomedical glue sling technique was performed on 82 patients...
