Temporal Bone Pathology of Traumatic Neuroma of Facial Nerve

Abstract

On autopsy, traumatic neuroma of the facial nerve was found at the temporal bone of a man who died of oropharynx carcinoma with multiple metastases. The neuroma developed. on the horizontal portion of the facial nerve at the Fallopian canal dehiscence and the temporal bone demonstrated chronic otitis media.
It has been occasionally suggested that long-term exposure of the facial nerve to chronic inflammation results in proliferation of neurofibrils leading to neuroma formation. Three dimensional reconstruction clearly showed an anatomical correlation between the Fallopian canal dehiscence and the neuroma.
