Facial Nerve Paralysis Treatment Conditions Uw Health Facial weakness or paralysis can occur after surgery to remove a vestibular schwannoma (acoustic neuroma). fortunately, with improved surgical techniques, improved diagnostic capabilities and facial nerve monitoring, it is much less common.*1 rinaldi et al in their study in 2012 showed that the size of the tumour was one of the most important factors in determining if facial nerve function. Complete flaccid paralysis. chronically denervated faces are characterized by soft tissue atrophy and soft tissue drooping. the atrophy results principally from chronic muscle denervation and loss of muscle bulk. while it may be surprising how much of the health and vitality of the face is related to its underlying muscle volume and.
Facial Paralysis Facial Nerve Reanimation Kochhar Plastic Surgery Masseteric nerve transfer the masseter nerve runs right next to the facial nerves and is an ideal choice for innervating the facial muscles when the facial nerve coming from the brain on the side of the paralysis cannot be accessed. because of its close proximity to the facial nerves and muscles, results from transferring the masseteric nerve to the facial nerve can be seen as early as 3.5 months. Masseteric facial nerve transfer for reinnervation of patients with an irreversible complete facial paralysis of less than 2 years duration has gained popularity ( fig. 11.3). “supercharging” of the facial nerve with the masseteric nerve has also been proposed for individuals with post paralysis with synkinesis to increase the voluntary. Nonetheless, the decision regarding whether to use cross facial nerve grafts or the masseteric nerve to power the muscle transplant or reinnervate viable facial musculature depends on the objectives of the surgery and individual patient factors, with the masseteric nerve being recommended in the case of bilateral moebius syndrome, older patients (age, >70 years), or patients with malignant. Reanimation surgery may be needed when a paralyzed facial nerve does not recover. this type of paralysis may occur as a result of a traumatic head injury or a stroke. persistent paralysis can also occur if a benign tumor called a facial neuroma grows on the seventh cranial nerve, which carries electrical signals from the brain to the facial.
