Abstract

SETHI, Ashwani; CHOPRA, Shamit; PASSEY, J. C  and  AGARWAL, A. K. Intraparotid Facial Nerve Neurofibroma: an Uncommon Neoplasm. Int. J. Morphol. [online]. 2011, vol.29, n.3, pp.1054-1057. ISSN 0717-9502.  http://dx.doi.org/10.4067/S0717-95022011000300066.

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.
