Abstract:
OBJECTIVE:To explore the clinical features, pathologic characteristics and treatments of the facial paralysis caused by temporal bone tumors.
METHOD:Retrospective analyzed the 23 clinical data of peripheral facial paralysis caused by temporal bone tumors, including 11 cases of facial nerve tumor: facial nerve neurilemmoma in 8 cases, facial nerve neurofibroma in 3 cases; 12 cases of temporal bone malignant tumor: temporal bone squamous cell carcinoma in 9 cases, chondrosarcoma in 1 case, rhabdomyosarcoma in 2 cases. All the patients accepted the CT scan examination and MRI examination. Twenty-three cases were surgically treated: facial nerve tumor resection were performed in 11 cases, among those, through mastoid approach in 7 cases, combined mastoid with middle cranial fossa approach in 3 cases, combined mastoid with parotid approach in 2 cases. Eight cases underwent facial nerve graft following the surgical removal of tumors. Twelve cases were temporal bone malignant tumor resection: among those, extended mastoidotympanectomy in 5 cases, subtotal temporal bone resection in 6 cases, total temporal bone resection in 1 case, all were treated by radiotherapies after surgeries.
RESULT:Whether the tumors go along the facial nerve in imaging is the major identification method to identify the facial nerve tumors or no-facial nerve tumors. During the 3-8 years follow-up, 10 patients who were totally removed the facial nerve tumor were no recurrence, 1 patient had tumors present. The recurrence rate of temporal bone malignancy was 41. 7% (5/12), 5 cases of Stell stage T2 and 5 cases of stage T3. The 5-year survival rate was 66.7% (8/12).
CONCLUSION:Most of facial nerve tumors that cause the facial palsy are benign, and no-facial nerve tumors are most common among the malignant tumors. CT and MRI films are valuable for the diagnosis. Operation is the major treatment, the manner of the operation bases on the type and the extent of the tumors. Facial nerve grafting can improve the facial neurological function after the tumor excision. Malignancy should be treated by combination of operation and radiotherapy, etc.
