Abstract:

A história natural dos schwanomas vestibulares ainda não é totalmente conhecida, mas a maioria destas lesões tende ao crescimento lento, algumas vezes sem qualquer manifestação clínica durante toda a vida do indivíduo, sendo em ocasiões achado de autópsias. Consideráveis avanços no conhecimento da anatomia da base do crânio, assim como os recursos tecnológicos de eletrofisiologia, como a monitorização intra-operatória têm possibilitado índices crescentes de preservação funcional do nervo facial e da audição. Devido a isso, a ressecção cirúrgica completa da lesão permanece sendo o tratamento de

Abstract:

Abstract MISME syndrome, also known as neurofibromatosis type-2 (NF2), stands for multiple inherited schwannomas, meningiomas, and ependymomas (MISME) in the peripheral and central nervous system. It is a rare disorder of autosomal dominant inheritance due to mutations of a tumor-suppressor gene on the chromosome 22q12. Clinically, it is characterized by multiple benign tumors arising in both the central and the peripheral nervous system, particularly from the bilateral vestibular nerve in more than 90% of the patients and more than two thirds of them develop spinal tumors.

The questionable value of word-recognition scores in determining hearing aid candidacy is discussed. The importance of considering nonaudiologic factors in determining hearing aid candidacy is also highlighted. Se reporta el caso de una mujer

Abstract:

Elderly patients with balance problems are at high risk for falls. When these same patients are also on anticoagulants, the consequences of a fall can be serious. Anticoagulant therapy increases the risk of cerebral hemorrhage. Even mild head trauma can cause a fatal cerebral hemorrhage when anticoagulants are used. However, this risk needs to be weighed against the possibility of spontaneous stroke. The decision to choose anticoagulant therapy can become even more complicated if the patient has an increased risk of falling. A case is presented of an 87-year-old female with balance problems, i

Abstract:

Vestibular schwannomas are histopathologically benign tumors arising from the Schwann cell sheath surrounding the vestibular branch of cranial nerve VIII and are related to the NF2 gene and its product merlin. Merlin acts as a tumor suppressor and as a mediator of contact inhibition. Thus, deficiencies in both NF2 genes lead to vestibular schwannoma development. Recently, there have been major advances in our knowledge of the molecular biology of vestibular schwannomas as well as the development of novel therapies for its treatment.

Giant vestibular schwannomas are seen in our country due to the late diagnosis and long duration of symptoms before diagnosis. These giant schwannomas are challenging to manage as most of the patients are having brainstem compression. Materials and Methods: Twelve cases of a giant vestibular schwannoma were operated in our department between May 2011 and December 2012.

The presence of vestibular schwannomas has long been considered an exclusion criterion for the diagnosis of schwannomatosis. Recently, 2 cases of vestibular schwannoma were reported in patients with schwannomatosis, leading to a revision of the diagnostic criteria for this genetic disorder. Overall, the relative infrequency of vestibular schwannomas in schwannomatosis is unexplained, and the genetics of this uncommon phenomenon have not been described.

Several vestibular schwannoma localized in the labyrinth have been reported worldwide. Since then 5 cases have been reported.

Abstract:

AbstractVestibular schwannomas are the most common cerebellopontine angle tumors. These tumors commonly present with ipsilateral dysfunction of acoustic, vestibular, trigeminal, and facial nerves. Vestibular schwannoma with involvement of contralateral facial nerve is very unusual, and whenever present, it is considered as a false localizing sign. It seems that displacement and distortion of the brainstem by the large mass lesion may lead to this atypical presentation. We report a case of vestibular schwannoma with contralateral abducens and facial nerve paresis.

Abstract:

AbstractThe current gold standard for diagnosing vestibular schwannomas is MRI with gadolinium-DTPA enhancement. This imaging modality is particularly useful in the detection of small intracanalicular tumours which can be missed by CT scanning. We present a case where MRI with enhancement suggested the presence of a 4 mm intracanalicular vestibular schwannoma. Surgical exploration of the internal auditory canal via a retrosigmoid approach, revealed no tumour, but inflammatory arachnoid matter around the vestibular nerve was found. A review of the audiological test results uncovered some result

AbstractThe dural tail on contrast-enhanced magnetic resonance (MR) images, frequently observed in meningiomas, has been used to distinguish between cerebellopontine angle meningiomas and vestibular schwannomas. We report on a 66-year-old female with vestibular schwannoma showing the dural tail on contrast-enhanced MR images. Histological examination revealed that the dural tail corresponded to the thickened dura mater comprising of collagen fibres and scattered hyalinization with no tumoral invasion.

Abstract:

Glossopharyngeal (that is, cranial nerve IX) schwannomas are extremely rare nerve sheath tumors that frequently mimic the more common vestibular schwannoma in their clinical as well as radiographic presentation. Although rare in adults, this tumor has not been reported in a child. The authors report the case of a 10-year-old boy who presented with several months of unilateral hearing loss. He was found to have a large right cerebellopontine angle tumor. Given the boy's primary complaint of hearing loss and the appearance of the lesion on imaging, the tumor was initially believed to be a schwan

Abstract:

The translabyrinthine approach is one of the favoured access routes for removal of vestibular schwannomas; however, total hearing loss in the operated ear is a predictable consequence. Here, we report a case in which a patient maintained serviceable hearing almost six years after classic translabyrinthine surgery. Possible explanations for the hearing preservation are discussed, as well as the feasibility of a modified translabyrinthine approach in attempting preservation of hearing following vestibular schwannoma surgery.

Symptoms related to HCP are expected to alleviate after resection of the tumor and decompression of the cerebrospinal fluid (CSF) pathways. However, some patients may require permanent cerebrospinal diversion even after surgery due to persistent HCP. In this study, the authors try to find out the factors associated with the requirement of CSF diversion after vestibular schwannoma surgery in cases of persistent HCP.

The extraordinary improvement of patient outcome after surgical treatment for vestibular schwannomas is relatively recent and has occurred mainly over the last 30 years. The introduction of microsurgical techniques has resulted in increasing degrees of precise anatomical and functional preservation of the facial and cochlear nerves. An expanded microsurgical technique accompanied by continuous electrophysiological monitoring has resulted in marked changes in the primary goals for this surgery.
