ABSTRACT

To compare sizes of the foramen ovale and rotundum in trigeminal neuralgia [TN] patients and healthy individuals on CT images. Twenty-one TN patients and 24 healthy volunteers were included in the retrospectively designed study, carried out at the Department of Anatomy, Medical School, Gaziantep University, Gaziantep, Turkey, between May 2004 and August 2009. The dimension of the foramen ovale on the cross-sectional images, and the foramen rotundum on coronal sections on CT images were examined. The mean sizes of the foramen rotundum on the right and left sides were 3.04x3.2 mm and 2.8x2.9 mm in TN patients, and 2.4x3.2 mm and 2.5x3.1 mm in controls. The mean sizes of the foramen ovale on the right and left sides were 4.8x6.04 mm and 4.9x5.5 mm in TN patients, and 3.7x8.2 mm and 4.1x7.6 mm in controls.The dimension of left and right foramens were not significantly different in both TN patients, and 3.7x8.2 mm and 4.1x7.6 mm in controls. The dimensions of left and right foramens were not significantly different in both TN patients and controls [p>0.05]. Furthermore, a statistically significant difference was not found between the foraminal dimensions of the TN patients and controls [p>0.05]. This study revealed that the sizes of foramen ovale and rotundum are highly symmetrical in both groups, suggesting that sizes of the foramina are not associated with the occurrence of TN

ABSTRACT

Se trataron 50 pacientes en el Hospital de Especialidades Centro Médico Nacional La Raza con neuralgia del trigémino, mediante dos procedimientos: a) microdescompresión vascular del trigémino mediante craniectomia asterional y b) compresión del ganglio de Gasser por punción per cutánea. El paciente eligió el procedimiento quirúrgico previa información detallada. A 22 pacientes se les realizó punción y a 28 microdescompresión. Las edades variaron de 38 a 80 años, 35 mujeres y 15 hombres. Los resultados a tres meses fueron buenos o excelentes en 25 pacientes con la microdescompresión y en 15pacientes con la compresión. A dos años los resultados seguían iguales a quienes se les realizó microdescompresión y en los pacientes tratados con compresión los resultados satisfactorios habían disminuido 59% de los casos. Se encontró compresión vascular en 96% de los casos de los pacientes que se realizó craniectomía. Tuvimos cinco pacientes con hipoacusia después de la microdescompresión y ocho con disestesia facial después de la compresión, y en dos casos de compresión el procedimiento no se pudo llevar a cabo por dificultades técnicas. Uno y otro procedimientos son seguros, con nula mortalidad, pero con mejores resultados a dos años con la microdescompresión vascular.


We treated 50 patients at the Hospital de Especialidades, Centro Médico Nacional La Raza, LMSS, in Mexico City, with trigeminal neuralgia by two procedures: a) microvascular decompression of the trigeminal nerve with asterional craniectomy, or b) compression of Gasser's nodule by percutaneous puncture. Each patient was allowed to choose one of the procedures after informed consent. Twenty two patients underwent percutaneous puncture, while 28 patients underwent microvascular decompression. Our study group comprised 35 females and 15 males between the ages of 38 and 80 years. After 3 months, we achieved good-to-excellent results in 25 patients with microvascular decompression and in 15 patients, with compression of Gasser's nodule. At 2 years follow-up, our results remained the same for microvascular decompression group while in the other group we observed only satisfactory results in 59% of cases. In craniectomy group, we found vascular compression in 96% of cases. Five patients presented hypoacusia after decompressive procedure and eight patients had facial dysesthesia after percutaneous procedure. In percutaneous group, procedures were cancelled due to technical difficulties in two cases. We conclude that both procedures are safe, with zero mortality. The microvascular procedure affords better results at 2 years follow-up.

ABSTRACT

Presentamos los hallazgos por RM de un caso de neuritis trigeminal bilateral como manifestación atípica de neurosífilis en un paciente varón, de 34 años, HIV + para demostrar la utilidad de la RM como método para la valoración postratamiento, arribando a las siguientes conclusiones: 1) la neuritis trigeminal constituye una presentación excepcional de la neurosífilis. No hemos encontrado reportes al respecto en la literatura imagenológica; 2) la RM con cortes de alta resolución y con gadolinio no sólo demuestran con claridad los cambios inflamatorios en los trigéminos sino que, además, podría detectar lesiones silentes o subclínicas (nuestro paciente mostraba realce bilateral y tenía manifestaciones clínicas sólo del lado derecho) y 3) la RM sin y con gadolinio es un método adecuado para valorar la respuesta al tratamiento en casos de neuritis trigeminal

ABSTRACT

La neuralgia del trigénio (NT) se asocia con múltiples lesiones intra y extracraneanas como son la compresión vascular arterial o venosa, ateroesclerosis, esclerosis múltiple, malformaciones arteriovenosas, etc. Se piensa que algunas de estas lesiones intervienen en la patogenia de la NT. Se presenta el caso de una mujer de 72 años con NT unilateral secundaria a la presencia de tuberculomas bilaterales de la tienda del cerebelo, y del surco olfatorio. Murió como consecuencia de leptomeningitis tuberculosa. Se revisan los conceptos actuales de la patogenia de la NT
