BACKGROUND AND PURPOSE A variety of approaches are employed for treatment of Chiari I malformation. They differ in extent of cranio-c ervical decompression. A technique based on arachnoid preservation and duroplasty was introduced in our department in 2001. The aim of the study is to compare between the previous and the present technique. MATERIAL AND(More)
The coexistence of schwannoma and meningioma in the same cerebellopontine angle (CPA) is uncommon. Especially, the presence of a single mixed tumour composed of demarcated or intermingled components of schwannoma and meningioma tissue is extremely rare. Such a phenomenon is mainly reported in a patient with NF2 or with history of previous irradiation. We(More)
OBJECTIVE Presentation of our experience in the treatment of anterior clinoidal meningiomas, including evaluation of factors that may affect early and long-term treatment outcomes. METHODS Thirty patients were operated with strategy of complete tumor resection using fronto-orbito-zygomatic approach. Outcomes were assessed by Glasgow Outcome Scale at(More)
OBJECTIVE Among pineal region lesions meningiomas are extremely rare and include falcotentorial and velum interpositum meningiomas. It is very difficult to discriminate between these two lesions and description of the clinical presentation and the surgical technique in approaching these tumors is limited. We respectively analyzed a series of patients(More)
BACKGROUND The treatment of chronic subdural hematoma (cSDH) is still charged of significant risk of hematoma recurrence. Patient-related predictors and the surgical procedures themselves have been addressed in many studies. In contrast, postoperative management has infrequently been subjected to detailed analysis. Moreover variable intravenous fluid(More)
OBJECTIVE The aim of the study is to determine which clinic, radiologic, and surgical characteristics of benign and atypical meningioma are associated with tumor progression. METHODS 335 patients who underwent gross-total resection of intracranial benign and atypical meningiomas between 2000 and 2009 were followed during the period of at least 3 years.(More)
BACKGROUND AND PURPOSE Posterior microlaminoforaminotomy is a surgical treatment option for lateral cervical disc herniation. This approach avoids injury of vital structures lying in front of the cervical spine and preserves mobility of the treated spinal segment. The authors present the outcome of 20 patients operated on using this method. MATERIAL AND(More)
Facial nerve (CN VII) palsy or even its transient paresis causes physical disability but is also a psychosocial problem. Immediately after vestibular schwannoma removal, different degrees of CN VII paresis occur in 20-70% of patients. Facial nerve paresis is observed in 10-40% after surgery of cerebellopontine angle meningiomas. Postoperative facial nerve(More)
BACKGROUND AND PURPOSE Lumbar discectomy with the METRx X-Tube system and operating microscope is a modification of microendoscopic discectomy. The aim of this study was to describe this method and present the results of treatment of the first 13 patients. MATERIAL AND METHODS Under general anaesthesia and fluoroscopic guidance, a guidewire was placed(More)
OBJECTIVE Guidelines for appropriate management of vestibular schwannomas in NF2 patients are controversial. In this paper we reviewed our experience with patients with NF2 for the results of surgical treatment with particular reference to hearing and facial nerve preservation. METHODS We included in the study 30 patients (16 women and 14 men) with the(More)
