[Reversible retrobulbar optic neuritis due to sphenoidal sinus disorders: two case studies]. / Neuritis óptica retrobulbar reversible por sinupatía esfenoidal: dos casos clínicos.

Optic neuritis are clinically demonstrated by a temporary but severe loss of vision and can be caused by a wide variety of diseases. It is unusual for sphenoidal sinusitis to co-exist with acute optic neuritis, so the simultaneous appearance of both diseases would invite aetiological suspicion. We present two cases where the first clinical manifestation of infectious sphenoidal pathology was retrobulbar optic neuritis, which reverted with treatment, medical in one case and surgical in the other, of the sinusitis.

Neuritis óptica retrobulbar reversible por sinupatía esfenoidal: dos casos clínicos / Reversible retrobulbar optic neuritis due to sphenoidal sinus disorders: two case studies

Las neuritis ópticas pueden estar producidas por una gran variedad de enfermedades y se manifiestan clínicamente como una pérdida de visión temporal pero severa. Es raro que sinusitis esfenoidales coexistan con neuritis ópticas agudas, por lo que su relación invita a la sospecha etiológica. Presentamos 2 casos en los que la primera manifestación de una afección infecciosa esfenoidal fue una neuritis óptica retrobulbar que revirtió tras el tratamiento, médico, en un caso, y quirúrgico, en el otro, de la sinusitis

[Complete facial palsy following surgery for acoustic nerve neurinoma: evolution and associated ophthalmological complications]. / Parálisis facial completa tras cirugía de neurinoma del acústico: evolución y complicaciones oftalmológicas asociadas.

OBJECTIVE: To evaluate the fraction of patients recovering to normal function after complete facial nerve paralysis secondary to acoustic neuroma surgery, and also to address the ophthalmologic complications associated with it and the therapeutic options. MATERIAL AND METHOD: We performed a retrospective review of 30 cases operated on in our department for acoustic neuroma and who, despite anatomical preservation of the facial nerve, developed a complete post-operative facial nerve paralysis (grade VI of House-Brackmann [HB]). We analyzed the evolution of the facial paralysis in relation to the tumour size, patient age, surgical approach and localization of the tumour. In addition, we studied the ophthalmologic complications and their treatment. RESULTS: Only 5 of the 30 cases studied (16.6 %) recovered to normal facial nerve function (HB grade I). We observed a tendency for a poor recovery of the cases with tumour size bigger than 2 cm, males, those older than 65 years and lesions resected by the translabyrinthine approach. Only 1 patient presented serious ophthalmologic complications. CONCLUSIONS: Our study reveals that only a small percentage of patients achieve total recovery of facial function. We have to be on the alert to ocular complications in this kind of patient.

Parálisis facial completa tras cirugía de neurinoma del acústico: evolución y complicaciones oftalmológicas asociadas / Complete facial palsy following surgery for acoustic nerve neurinoma: evolution and associated ophthalmological complications

Objetivo: Averiguar la fracción de pacientes intervenidos de un neurinoma del acústico que recuperan la función normal del nervio facial tras una parálisis facial completa postoperatoria, atendiendo a las complicaciones oftalmológicas asociadas a la falta de recuperación y sus opciones terapéuticas. Material y método: Se realiza un estudio retrospectivo de 30 pacientes intervenidos de neurinomas del acústico en nuestro servicio que, con preservación anatómica del nervio facial, presentaron una parálisis facial completa (grado VI de House-Brackmann [HB]) postoperatoria. Se analiza la evolución de la parálisis en función del tamaño tumoral, la edad del paciente, el abordaje quirúrgico y la localización del neurinoma. También se estudian las complicaciones oftalmológicas surgidas y su tratamiento. Resultados: De los 30 pacientes estudiados, sólo 5 (16,6 %) recuperaron la función normal facial (grado I de HB). Se observó una tendencia a una peor recuperación en los casos con tamaño tumoral mayor de 2 cm, de sexo masculino, edad mayor de 65 años y abordados por vía translaberíntica. Sólo un paciente presentó complicaciones oftalmológicas graves. Conclusiones: Nuestro análisis revela que un escaso porcentaje de pacientes recupera de forma completa su función facial, y que es necesario estar alerta ante posibles complicaciones oculares en este espectro de pacientes
