ABSTRACT
Intraparotid facial nerve neurofibromas are a rare entity, and are grossly and histopathologically distinct from the comparatively more prevalent schwannomas. We report a rare case of an intraparotid facial nerve neurofibroma with intratemporal extension in a 48-year-old female. The tumor was surgically excised with cable grafting of the facial nerve. Electroneurography may eventually assist in the preoperative diagnosis. Facial nerve resection should be more readily contemplated in a patient with neurofibroma than in a patient with schwannoma; however, facial nerve preservation with serial follow-up electroneurography and computerized tomography remains a viable option in patients with small facial nerve neurofibromas when electrical testing reveals minimal evidence of progressive neural degeneration. Close monitoring, especially in neurofibromas associated with Von Recklinghausen's disease, is mandatory because of an increased risk of sarcomatous degeneration.
RESUMEN
Los neurofibromas intraparotídeos del nervio facial son una entidad poco frecuente, macroscópicamente e histopatológicamente diferentes de los comparativamente más frecuentes schwannomas. Se presenta un caso raro de un neurofibroma del nervio facial con extensión intraparotídea intratemporal en una mujer de 48 años de edad. El tumor se extirpó quirúrgicamente con injerto del nervio facial. La electroneurografía puede llegar a ayudar en el diagnóstico preoperatorio. La resección del nervio facial debe ser realizada con mayor facilidad en un paciente con neurofibroma que en un paciente con schwannoma, sin embargo, la preservación del nervio facial con electroneurografía de seguimiento y tomografía computarizada sigue siendo una opción viable en pacientes con pequeños neurofibromas del nervio facial, cuando las pruebas eléctricas revelan mínima evidencia de degeneración neuronal progresiva. Una estrecha vigilancia, especialmente en los neurofibromas asociados con la enfermedad de Von Recklinghausen es fundamental debido al aumento del riesgo de degeneración sarcomatosa.
