BACKGROUND:Tuberculum sellae meningiomas is a serious challenge for neurosurgeons. It accounts for up to 10% of all intracranial meningiomas. The difficulty in surgically excising a Tuberculum sellae meningioma comes from its anatomical relationship to the optic nerves and chiasm and to the anterior cerebral and internal carotid arteries and their perforators. The authors discuss the main approaches and the complications based on their experience in comparison to previously reported data. METHODS: We report our personal case series of 38 patients with Tuberculum sellae meningiomas; 36 patients under went craniotomy for tumor resection (12 bifrontal, 12 pterional, 6 supraciliary, 4 unilateral frontals, and 2fronto-orbito-zygomatic); in two patients, the excision was performed through an endoscopic endonasal approach. The Simpson grade of meningioma resection as well as the non-visual morbidity and the mortality rates were analyzed. RESULTS: Thirty-one patients had Simpson grades 1 and 2 excisions, while seven had Simpson grade 4 excisions. The overall rate of non-visual morbidity was 13.15% (5 of 38 patients) and mortality was 5.3% (2 of 38). CONCLUSION: The primary symptom leading to the diagnosis of a Tuberculum sellae meningioma is visual compromise and the main goal of surgery is to achieve improvement of vision. Favorable outcomes were achieved with appropriate selection of surgical approach. More studies are necessary to define the prognostic factors for patients in this scenario.

RESUMOO artigo apresenta reflexões sobre a noção de comunicação ambiental, a fim de contribuir na construção do conceito que define esta área considerada especializada e de interface. Defende-se que tal área, situada no imbricamento entre os campos da comunicação e do meio ambiente, caracteriza-se por englobar fundamentos e perspectivas de ambos, ressaltando seu caráter interdisciplinar. Inicialmente são apresentadas as bases epistemológicas dos dois campos, com o objetivo de enfatizar as articulações práticas e teóricas que ocorrem entre eles. Faz-se, então, uma revisão de literatura acerca do termo "comunicação ambiental", considerando autores nacionais e internacionais, e argumenta-se que esta não se resume a tratar de temáticas características da área ambiental. Por fim, busca-se refletir sobre as possibilidades da comunicação ambiental para auxiliar nas ações de enfrentamento dos problemas socioambientais contemporâneos.Palavras-chave: comunicação; meio ambiente; comunicação ambiental; interfaces; epistemologia. ABSTRACT This paper provides reflections over the notion of environmental communication, seeking to contribute on the construction of the concept that defines this kind of communication, considered specialized and of interface. The argument stated is that environmental communication is characterized by embracing perspectives and fundamentals of both the communication and the environmental fields, since it is situated in their interweave, emphasizing its interdisciplinary character. Initially, the epistemological bases of both fields are presented, in order to highlight the practical and theoretical articulations that occur between them. A literature review about the term is then provided, considering national and international authors, followed by the argumentation that environmental communication is not simply about dealing with thematic features of the environmental field. Finally, some reflections on its possibilities to assist in coping actions of contemporary social and environmental problems are offered.
