Two cases of intraparotid facial nerve neurogenic tumor are reported. Case 1 is a 28-yearold male and case 2 is a 59-year-old male. We obtained the following interesting results from an analysis of facial nerve neurogenic tumor cases.
(1) The prevalence is high among women in their 40's and 50's.
(2) The prevalence is very high in the temporal bone (particulary the vertical region and the horizontal region).
(3) Most of the histological diagnoses are schwannomas.
The disease features tumors originating at the parotid region. No particular findings are observed except for swelling at the parotid region, and no characteristic findings are seen radiographically. Accordingly, preoperative diagnosis of the disease is rather difficult. The first-choice therapy for the disease is surgical treatment. We discuss the necessity of surgery at an early-stage for a better prognosis of facial nerve paralysis.
