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 postoperative 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.

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.
