Epub 2014 Apr 29 Background Posterior fossa craniotomies can be complicated by cerebrospinal fluid (CSF) leaks, infection, meningitis, neurologic deficits, and intracranial hypotension caused by defective closure of the dura. Secondary dural closures such as pericranial graft, muscle graft, glue, sealants, or fat graft are used. However, there have been few studies examining the use of sealants with a.

Once medical treatments fail, surgical intervention may be advocated. 1-3 Percutaneous lesions of the trigeminal nerve or ganglion, exploration of the posterior fossa for microvascular decompression (MVD), partial sensory rhizotomy (PSR) at the nerve root entry zone, and, more recently, stereotactic radiosurgery have been shown to ameliorate. Posterior fossa decompression with duraplasty is routinely used for the treatment of Chiari malformations. It has been traditionally believed that this procedure requires a watertight seal with primary closure of the dura with either pericranium or allograft. In this study, the authors evaluated two synthetic dural substitutes in this patient population for feasibility of use and. We analyzed the outcome of posterior fossa decompression accompanied by widening of the cisterna magna, without disturbing the arachnoid, in patients with Chiari I malformation (CMI) associated with syringomyelia. Twenty-five adult patients with CMI and syringomyelia, who underwent surgery between October 2000 and December 2008, were enrolled in this study. All patients underwent foramen. In the initial study in 1978, Nyland and Krogness demonstrated the small relative size of the posterior fossa in patients with Chiari I malformation. 21 Later, using CT scanning Dr Batzdorf and his colleagues demonstrated that, compared to normal persons, the ratio of the posterior fossa volume compared to the supratentorial volume was. Hemifacial spasm (HFS) is a rare neuromuscular disease characterized by irregular, involuntary muscle contractions on one side (hemi-) of the face (-facial). The facial muscles are controlled by the facial nerve (seventh cranial nerve), which originates at the brainstem and exits the skull below the ear where it separates into five main branches.. This disease takes two forms: typical and.

expanded posterior fossa which is still enclosed and effectively reduces the size of the foramen magnum. The surgeons used this technique on seven patients they saw between 1994-2004. The patients had all had decompression surgery at other institutions, were suffering from symptoms, and had demonstrable cerebellar slump on MRI Decompression surgery describes a number of different procedures. This type of surgery is used to remove the bone that is compressing the cerebellar tonsils. When successful, this reduces pressure on the brain and spinal cord.
