Primary tumors of the facial nerve are relatively uncommon. The biggest part of them are neurinomas. The majority of cases involve the intratemporal segment of the nerve. The neurogenic sarcoma, the neurofibroma, and the granular cell tumor are less common.
A 49-year-old man presented in September 2004 with a right facial paresis. He had a 4-year history of recurrent right facial paresis. The patient had undergone a decompression of facial nerve and a radical mastoidectomy in 1998.
Following the topognostic examinations a CT-scan of the temporal bone was made. CT-scans showed a mass in the tympanic cavity. Transmeatal surgery disclosed a tumor of the tympanic segment of the facial nerve measuring 8 mm. Pathological examination indicated the diagnosis of neurinoma of the facial nerve.
The tumor was surgical resected completely. Reconstruction was performed by a greater auricular nerve interposition graft.
Because there are no specific symptoms of primary tumors of the facial nerve the diagnosis is difficult. Therefore a extensive diagnostic in such cases is important.
