Download Facial Nerve Disorders Brochure. The various treatment programs including medications, surgery, and reanimation procedures have been used to improve overall facial function. State of the art diagnostic testing has been able to predict the outcome of a patients with facial nerve weakness. Electrical stimulation may be used as well in order to assist our patients during their recovery. Twitching, weakness or paralysis of the face is a symptom of some disorders involving the facial nerve.

A Discussion of Facial Nerve Problems
Every structure contained within the temporal bone in close proximity to the facial nerve is at risk during intratemporal bone surgery on the facial nerve. We present a review of the causes of injuries to these structures and of ways to prevent such injuries. This review includes information drawn from pertinent literature, from the author's experience managing patients undergoing temporal bone surgery for a variety of facial nerve disorders between and , from an analysis of 43 of our patients whose hearing was evaluated before transmastoid facial nerve surgery and again 6 months after surgery, and from the experiences of colleagues. We found that the most frequent complication of intratemporal facial nerve surgery is auditory involvement. Structures less commonly injured during transmastoid decompression of the facial nerve included the facial nerve itself, the chorda tympani nerve, the balance function of the labyrinth, the cochlea, the ossicles, the sigmoid sinus and superior petrosal vein, the middle meningeal artery and the stylomastoid artery, the dura, and the brain. We review all of these complications, as well as discuss the incidence of cerebrospinal fluid leak and infection which also may result from this type of surgery.
Loss of auditory function in microvascular decompression for hemifacial spasm
Metrics details. We performed a retrospective case review of all patients having undergone facial nerve decompression for severe refractory BP between and at our tertiary referral center. Demographics, timing between onset of symptoms and surgical decompression, degree of facial nerve dysfunction pre- and post-operatively, follow-up length after surgery and postoperative complications were recorded. Facial nerve dysfunction was assessed using the House-Brackmann HB scale. Electroneuronography, electromyography and imaging results were assessed when available.
Three patients suffered a profound hearing loss in the ear on the operated side, and one lost hearing function totally. In addition, 24 patients had a moderate elevation in the pure-tone threshold at one or more octave frequencies. Of these, 16 patients experienced a hearing loss at only one frequency Hz , while eight had a threshold evaluation of no more than 20 dB in the speech frequency range , , and Hz.
