Multislice Computed Tomography in Cases With Facial Nerve Paralysis Due to Temporal Bone Trauma

• Conditions: Facial Nerve Paralysis

• Registration Number: NCT03469427
• Lead Sponsor: Assiut University

Brief Summary

Facial nerve paralysis is a disfiguring complication which occurs in 7-10 % of temporal bone fractures.

The onset of paralysis may be immediate, delayed or undetermined, the latter of which often occurs in unconscious patients with accompanying life-threatening complications.About one fourth has complete paralysis.

Detailed Description

Facial nerve paralysis might have variable etiologies apart from idiopathic Bell's palsy, Congenital, infectious, inflammatory, neoplastic, neurological, toxic, iatrogenic and atraumatic causes.

Surgical intervention is indicated if 90-95% loss of function is seen at the very early period on Electroneuronography or if there is axonal degeneration on Electromyography lately with no sign of recovery.

High-resolution multislice computed tomography of the temporal bone is routinely required for evaluation of traumatic facial paralysis. High-resolution multislice computed tomography is known to be the best method for evaluating the intratemporal course of the facial nerve, but it has some limitations as well. Occasionally, the surgeon may encounter facial nerve injuries which have not been revealed in the preoperative computed tomography.

There are limited data in recent medical publications evaluating the diagnostic value of temporal bone High-resolution multislice computed tomography in the evaluation of traumatic facial paralysis. Therefore, in this study,the investigators will compare the findings of preoperative high-resolution multislice computed tomography with surgical findings to determine the diagnostic value of computed tomography.
