Facial Nerve Paralysis Clinical Trial
Official title:
Reliability of Multislice Computed Tomography Scan in Cases With Facial Nerve Paralysis Due to Temporal Bone Trauma
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.
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.
