BACKGROUND AND OBJECTIVES Abnormal muscle response (AMR) to the electrical stimulation of a branch of facial nerve is a specific electrophysiological feature of primary hemifacial spasm (HFS). The aim of this study was to evaluate the value of AMR monitoring during microvascular decompression surgery (MVD), and the correlation between the AMR changes and(More)
Runx2, of the Runx family, is an essential transcription factor that controls bone and tooth development by regulating osteoblast and odontoblast differentiation. However, the function of Runx2 in late stage odontoblast differentiation is not clear. We studied the function of Runx2 in dentinogenesis by generating transgenic mice expressing Runx2(More)
OBJECTIVE To explore pathological mechanisms of central hyponatremia and its treatment. METHODS Synchronous assay was made for changes of atrial natriuretic peptide (ANP), brain natriuretic peptide (BNP), endogenous digitalis-like substance (EDLS), antidiuretic hormone (ADH) in blood, and Na(+) concentrations in blood and urine, and plasma- and(More)
To summarize our experience and lessons of microvascular decompression surgery for trigeminal neuralgia caused solely by venous compression. Fifteen patients with idiopathic trigeminal neuralgia caused by venous compression only underwent microvascular decompression. The entire course of the trigeminal root was explored thoroughly; and coagulating and(More)
Surgeons often rely on intraoperative electrophysiological monitoring to determine whether decompression is sufficient during microvascular decompression surgery for hemifacial spasms. A new monitoring method is needed when an abnormal muscle response is occasionally not available or is unreliable. This study was an observational clinical trial exploring a(More)
Regardless hemifacial spasm (HFS) or trigeminal neuralgia (TN) is commonly caused by an offending artery, 36 cases caused by an arteriovenous malformation (AVM) have been reported in the literature. However, the concurrent HFS and TN caused by AVM have never been reported so far. We reported a case of coexistent HFS-TN associated with a huge AVM, and the(More)
BACKGROUND As an etiological treatment of trigeminal neuralgia (TN) and hemifacial spasm (HFS), microvascular decompression (MVD) has been popularized around the world. However, as a functional operation in the cerebellopontine angle (CPA), this process can be risky and the postoperative outcomes might not be good enough sometimes. OBJECTIVE In order to(More)
BACKGROUND Clear cell meningioma (CCM) is a rare meningioma, with radiologic features not well characterized in literature. The purpose of this study was to describe and characterize the clinical features and imaging findings of CCM. MATERIALS AND METHODS The computed tomography (n = 16) and magnetic resonance (n = 23) images of 23 patients (12 men and 11(More)
Multiple neurovascular compression is present in about 38 % cases of hemifacial spasm (HFS). In these cases, the vertebral artery (VA) compresses another vessel, which in turn compresses the nerve. This type was named as “the tandem type”. In the tandem type, the real offending vessel is often concealed by the VA. It is sometimes neglected by the surgeons.(More)
OBJECTIVE During microvascular decompression surgery for trigeminal neuralgia, surgeons will encounter various kinds of veins that block the approach to or compress the trigeminal nerve. The aim of this study was to present our experience in managing different kinds of veins. METHODS This was a retrospective study of 21 patients with trigeminal neuralgia,(More)
