Abstract

A 52-year-old man presented to our emergency department with an acute onset of right-sided facial nerve (FN) palsy of House-Brackmann grade V. Electroneurography (ENoG) was conducted with no response at the right FN, as compared with the left FN (0%). We performed a biopsy of the right middle ear mass and histological studies showed the tumor to be neuroendocrine tumors (NET) of the middle ear. We resected the tumor with canal wall down mastoidectomy and reconstructed the posterior meatal wall with soft tissue. Three months after surgery, the FN paralysis had improved with House-Brackmann grade II. We reviewed cases of NET with FN palsy, and nine patients, including our case, have been reported. Our case is the first report of ENoG for the description of FN palsy due to NET. Although the ENoG value was 0%, it was remarkably improved by surgery. The other cases of NET patients with FN palsy also recovered FN function after surgery. These results suggest that it is recommended to perform the total resection of the tumor to improve the FN function.
