Abstract:
A few approaches can be used to decompress traumatic facial nerve paralysis including the middle cranial fossa approach or transmastoid approach depending on the site of injury. In some specific situation of treating traumatic facial nerve palsy whose injured site was confined from the geniculate ganglion to the second genu, transcanal endoscopic approach for facial nerve decompression can be used. We performed two cases of total endoscopic transcanal facial nerve decompression in patients with traumatic facial nerve palsy. After a six month follow-up, both patients showed improvement in facial function by 2 grades according to House-Brackmann grade system. In terms of treatment outcomes, total transcanal endoscopic facial nerve decompression for traumatic facial nerve palsy is an alternative for lesions limited to the tympanic segment I, and has an advantages of being minimally invasive and is cosmetically acceptable without an external scar or bony depression due to drilling.
