Restoration of orbicularis oculi muscle function in rabbits with peripheral facial paralysis via an implantable artificial facial nerve system
The purpose of the present study was to restore orbicularis oculi muscle function using the implantable artificial facial nerve system (IAFNS). The in vivo part of the IAFNS was implanted into 12 rabbits that were facially paralyzed on the right side of the face to restore the function of the orbicularis oculi muscle, which was indicated by closure of the paralyzed eye when the contralateral si...

متن کاملIntratemporal facial nerve ultrastructure in patients with idiopathic facial paralysis: viral infection evidence study.
UNLABELLED The etiology of idiopathic peripheral facial palsy (IPFP) is still uncertain; however, some authors suggest the possibility of a viral infection. AIM to analyze the ultrastructure of the facial nerve seeking viral evidences that might provide etiological data. MATERIAL AND METHODS We studied 20 patients with peripheral facial palsy (PFP), with moderate to severe FP, of both gende...
متن کاملA silent period in orbicularis oculi muscles of humans.
Surface electromyographic activity was recorded bilaterally from orbicularis oculi muscles when subjects relaxed and contracted eyelid muscles. Cutaneous reflex responses were evoked during both the relaxed and contraction states. Following reflex elicitation periods of muscle silence in orbicularis oculi were observed for about 10 to 15 ms after the ipsilateral R1 response and for up to 100 ms...
متن کاملDynamic muscle transfer in facial nerve palsy: the use of contralateral orbicularis oculi muscle.
The aim of the study is to describe the results of dynamic muscle transfer with an orbicularis oculi muscle flap from the contralateral side to the paralyzed side in patients with House-Brackmann grade 6 facial nerve palsy. This case series included six patients who underwent dynamic muscle transfer with a flap of healthy orbicularis oculi muscle fibers from the contralateral side into the para...
