Although microvascular decompression (MVD) has been widely accepted as an effective treatment of trigeminal neuralgia (TN), some patients have not been cured. To improve the postoperative outcome, the surgical procedure should be further refined. This is a retrospective study.

This study focused on the mechanosensitive channel Piezo2 and cytokine IL-6. The chronic constriction injury of infraorbital nerve in SD rats was used to establish the TN model.

However, it remains unknown whether exposure of human liver cancer (HepG2) cells to borax affects the gene expression of these cells. HepG2 cells were treated with 4 mM borax for either 2 or 24 h.

As previous studies implied that inflammatory cytokines induced by demyelination following the nerve injury may be the initiated factor causing neuropathic pain, we attempt to analyze the correlation between cytokines and these hyperactive cranial nerve disorders.
Method: The consecutive patients whose diagnosis were confirmed by microvascular decompression surgery as primary TN or HFS caused by vascular compression and healthy volunteers between March and May 2018 in XinHua Hospital Shanghai JiaoTong University School of Medicine were recruited.
The chronic constriction injury (CCI) of the infraorbital nerve (ION) has been used to establish an animal mode of trigeminal neuralgia (TN), but key parameters of the model have not been quantified until now. The aim of the study was to quantify a standard of pain threshold to evaluate a successful TN model in Sprague-Dawley (SD) rats. Forty-eight adult SD rats (200-220 g) underwent chronic constriction injury of the infraorbital nerve.

Design: Prospective comparative study.
Setting: University affiliated hospital.
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: Glossopharyngeal neuralgia (GPN) is an uncommon craniofacial pain syndrome caused by neurovascular conflict. Compared to trigeminal neuralgia or hemifacial spasm, the incidence of GPN was very low. Until now, little is known about the long-term outcome following microvascular decompression (MVD) process.
View Article and Find Full Text PDFIn most hemifacial spasm cases, the spasm initiates from the orbicularis occuli muscle and gradually spreads downwards to the orbicularis oris and buccinator muscles. Seldomly, the spasm might start from the orbicularis oris and buccinator muscles and develop upwards, which has been called as atypical hemifacial spasm (aHFS). Until now, little is known about its pathogenesis and the efficacy of microvascular decompression (MVD) surgery.

Methods: Using a one-pot aqueous approach, near infrared-emitting CdTe was produced. After detection of its physicochemical characteriistics, it was conjugated with RGD.
Background: Despite the wide adoption of the abnormal muscle response (AMR) to electrical stimulation of the facial nerve during microvascular decompression (MVD) surgery, the value of AMR in the prognosis of the postoperative outcome is still controversial. In order to better use this intraoperative electrophysiology, it is necessary to further address the relationship between AMR and postoperative results.
Methods: Three hundred and thirty-two patients with hemifacial spasm (HFS) in whom MVD surgery was performed and in whom AMR was available were finally enrolled in this study.

Background: Anterior cervical discectomy and fusion is currently the most commonly used technique in cervical surgery. But the implantation of a traditional plate is time-consuming and exposes the patient to additional adverse events. In this study, we analyzed results in patients who underwent anterior cervical discectomy and fusion with C-JAWS fixation.

Objective: To evaluate the clinical value of C-JAWS in anterior cervical discectomy and fusion (ACDF) surgery.
Methods: Between January 2012 and December 2013, nine consecutive patients with cervical spondylopathy underwent ACDF process using a polyetheretherketone cervical spacer prefilled with bone substitute and secured by a cervical compressive staple in our department. The Neck Disability Index (NDI) score and visual analogy scale (VAS) of neck or arm pain as well as radiographic examination were adopted to assess the postoperative outcome and fusion.
Although the microvascular decompression (MVD) surgery has become an effective remedy for cranial nerve rhizopathies, it is still challengeable and may result in a fatal sequel sometimes. Therefore, the operative skill needs to be further highlighted with emphasis on the safety and a preplan for management of postoperative fatal complications should be established. We retrospectively analyzed 6974 cases of MVD.

Background: Although Teflon is widely adopted for microvascular decompression (MVD) surgery, it has never been addressed for failure analysis. This study analyzed the reasons for failed MVDs with emphasis on the Teflon sponge.
Methods: Among the 685 hemifacial spasm cases between 2010 and 2014, 31 were reoperated on within a week because of unsatisfactory outcome, which was focused on in this study.
Hemifacial spasm (HFS) or trigeminal neuralgia (TN) is a kind of hyperactivity disorder of cranial nerves caused by vascular compression. However, sometimes, the disease may arise from nerve damage produced by tumors, which was called as symptomatic HFS/TN. Until now, little is known about the exact mechanism and the necessity of microvascular decompression (MVD) regarding the tumor-induced HFS/TN, which is necessary to be retrospectively analyzed in a considerable sample.

Background: Bilateral hemifacial spasm (HFS) is very rare. The literature contains only 32 clinical reports. Although microvascular decompression (MVD) is widely accepted as effective therapy for HFS, the etiology and surgical treatment of bilateral HFS are seldom addressed.

Background: Postherpetic neuralgia (PHN) is the most common complication following an episode of acute herpes zoster. The curative effect of current treatments is limited.
Objectives: The purpose of this paper is to report a new treatment for PHN with a combination of dorsal root entry zone lesion (DREZotomy) and spinal cord stimulation (SCS).
Microvascular decompression (MVD) has been accepted worldwide as a reasonable treatment for hemifacial spasm (HFS); however, resolution of the HFS is often gradual. To conclude the delayed relief rate of the MVD for the treatment of HFS, we conducted a systematic review. Using the keywords delayed relief, hemifacial spasm, or microvascular decompression, articles published in English-language journals and indexed in PubMed between June 1, 1994 and June 1, 2014 on the treatment of HFS with emphasis on delayed relief were considered for this study.

A total of 2500 women with ultra-early pregnancy (amenorrhea ≤ 35 days) were randomly divided into 5 groups with gradually decreased dose of oral mifepristone from 150 to 50 mg followed by 200 µg of oral misoprostol 24 hours later. The primary end point was complete abortion without surgical intervention.

Background: Although microvascular decompression (MVD) surgery has been widely accepted as an effective treatment for hemifacial spasm (HFS), delayed relief cases have been frequently reported. Therefore, the value of an immediate redo MVD should be discussed.
Methods: This study included 1,435 HFS patients who underwent MVD with intraoperative abnormal muscle response (AMR) monitoring from 2011 through 2013 at XinHua Hospital.
Microvascular decompression has been now accepted worldwide as a reasonable treatment for trigeminal neuralgia, yet, as a functional operation in the cerebellopontine angle, this process may be risky and the postoperative outcomes might not be good enough sometimes. To assess the effectiveness and safety of microvascular decompression for treatment of trigeminal neuralgia, we conducted a systematic review. Using the keywords "trigeminal neuralgia", "microvascular decompression", or "neurovascular conflict", manuscripts published in English-language journals and indexed in PubMed between January 1, 2000 and June 1, 2013 on the treatment of trigeminal neuralgia (TN) with microvascular decompression were considered for this study.
