Resumo: | The authors review the evolution of the surgical strategy regarding vestibular nerve schwannomas. The classic neurosurgical goal aims to remove the tumor completely. Presently, we believe this approach has changed significantly. Both the preservation of the facial nerve and tumor resection are the main objectives of the surgery. In this review, we place a special emphasis to the management of large tumors (grade 3 and 4 of Koos Scale) and the quality of life of patients after the surgery.We describe an innovative imaging technique used in Portugal, which is performed at the Lusíadas Hospital, in Lisbon. All the patients treated at the Skull Base and Neurorhinology Department of the Hospital de Egas Moniz (Lisbon) are pre-surgically evaluated by MRI and Diffusion Tensor Imaging. Diffusion Tensor Imaging allows to determine the location of the facial nerve by means of Tractography. Cranial nerve Tractography contribute to successful skull base otoneurosurgeries, particularly by lowering the risk of nerve injury during cerebellopontine angle surgeries and reducing the time spent to locate fiber bundles intra-operatively. |

Se, no passado, a exérese total do tumor era o objectivo principal da cirurgia, no presente esta abordagem mudou de modo significativo. A preservação do nervo facial constitui um dos principais objectivos da cirurgia, assim como a exérese do tumor. É dado especial ênfase ao tratamento dos tumores de grandes dimensões (grau 3 e 4 da Escala de Koos) e sua relação com a qualidade de vida do doente no pós operatório.É descrita uma técnica de imagem inovadora em Portugal realizada no Hospital Lusíadas, em Lisboa, utilizada pela Unidade Funcional de Cirurgia da Base do Crânio e Neurorrinologia do Hospital de Egas Moniz, em Lisboa: a Tratografia do nervo facial por Difusão de Imagem, por Ressonância Magnética. Esta técnica permite conhecer, no pré operatório, o trajecto do nervo facial no seu segmento cisternal e sua relação anatómica com o tumor localizado ao ângulo ponto-cerebeloso.Sociedade Portuguesa de Otorrinolaringologia e Cirurgia de Cabeça e Pescoço2015-12-11info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdfhttps://doi.org/10.34631/sporl.596https://doi.org/10.34631/sporl.596Portuguese Journal of Otorhinolaryngology and Head and Neck Surgery; Vol. 53 No. 3 (2015): Setembro; 173-176Revista Portuguesa de Otorrinolaringologia e Cirurgia de Cabeça e Pescoço; Vol. 53 Núm. 3 (2015): Setembro; 173-176Revista Portuguesa de Otorrinolaringologia-Cirurgia de Cabeça e Pescoço; Vol. 53 N.º 3 (2015): Setembro; 173-1762184-6499reponame:Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos)instname:Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãoinstacron:RCAAPporhttps://journalsporl.com/index.php/sporl/article/view/2761https://journalsporl.com/index.php/sporl/article/view/2761/763Neto d'Almeida, GonçaloMarques, LuisGonçalves Pereira, PedroEscada, Pedro Albertoinfo:eu-repo/semantics/openAccess2024-06-06T13:00:12Zoai:journalsporl.com:article/2761Portal AgregadorONGhttps://www.rcaap.pt/oai/openairemluisa.alvim@gmail.comopendoar:71602024-06-06T13:00:12Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos) - Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãofalse |
