The extended endoscopic endonasal approach is a promising minimally invasive alternative for selected cases with sellar, parasellar or clivus lesions. As techniques and technology advance, this approach may become the procedure of choice for most lesions and should be considered an option in the management of the patients with these complex pathologies by skull base surgeons.
Intranasal meningoencephaloceles have historically been managed by neurosurgeons, although their main clinical manifestations are rhinological. Recent advances in endoscopic skull base surgery has significantly improved the treatment of these lesions and consequently diminished appreciable surgical morbidity. We report an ethmoidal meningoencephalocele case operated on by endonasal endoscopic approach for removal of the lesion and reconstructing the associated skull base. From this experience, we conclude that removal of the lesion and watertight closure of the skull base irrespective of the size of the mass and anterior skull base defect are the operation's most important aspects.
Los meningiomas del surco olfatorio representan el 10% de los meningiomas intracraneales, se originan de la lámina cribosa del etmoides, la sutura fronto-esfenoidal y el plano esfenoidal. Son tumores en su mayoría benignos y potencialmente curables, la recurrencia ocurre en grado variable siendo el grado de resección quirúrgica el predictor más importante de recurrencia. En este artículo se exponen los resultados alcanzados con el abordaje endonasal endoscópico extendido transcribiforme en pacientes con meningiomas del surco olfatorio en el servicio de neurocirugía del hospital clínico quirúrgico Hermanos Ameijeiras. La serie fue de 12 pacientes donde la cefalea, la anosmia y los trastornos neuropsicológicos fueron los síntomas predominantes. Los tumores tuvieron un tamaño ≥ a 6 cm en el 50% de los casos y con el abordaje endonasal endoscópico extendido transcribiforme se alcanzó una resección total con Simpson I en el 92% de los enfermos. Los límites del abordaje endonasal endoscópico en la fosa anterior se encuentran en constante extensión, siendo el abordaje endonasal endoscópico extendido transcribiforme la opción ideal y prometedora para los pacientes con Meningiomas del surco olfatorio.
Objectives: Pituitary adenomas are the most common disorders of the sellar region seen in neurosurgical practice .Surgical excision through the transsphenoidal route is recognized as the best option to treat these lesions and the endonasal endoscopic approach (EEA) has been introduced in many centers. This article analyzes results using this technique. Material and methods: EEA was used to operate on 278 patients at the Neurosurgery Department of "Hermanos Ameijeiras" Hospital in Havana from January 2005 to December of 2011. Results: Two hundred thirty eight patients had pituitary macroadenomas and forty had microadenomas. Ninety two were functioning adenomas (52 GH, 34 ACTH and 6 PRL) and one hundred eighty six were non-functioning. Gross total resection was achieved in 92.4% and subtotal resections in 7.5%. Complications occurred in 25 patients; diabetes insipidus was permanent in 11 cases. Conclusion: Because of the remarkable results for treating pituitary lesions, EEA has become a valuable technique in neurosurgical practice and in many centres has become the first option to consider in pituitary surgery.
El siguiente trabajo constituye una nota técnica sobre un nuevo proceder endoscópico de colocación de catéteres ventriculares permanente a través del cuerno occipital. Se colocaron 20 catéteres permanentes utilizando el sistema DECK con un endoscopio Hopkins II de 30°, diámetro 2,7 mm y longitud 30 cm, con vainas y canales de trabajos. La posición del catéter fue evaluada por tomografía de cráneo realizada a las 24 horas de la cirugía, obteniéndose una posición a (óptima) en el 95% de los casos, con una distancia promedio de 10,5 cm desde la tabla externa del hueso occipital al cuerno frontal. En ninguno de los casos disfuncionó el sistema derivativo y un solo paciente presentó como complicación un hematoma del lecho quirúrgico.
