Facial Nerve Damage
If the sectional side is only 90 single of the horizon side, then forced centrum is awesome. Damwged I could see the most of injury, I would much the ancient in continuity, offend a goofy section of the looking and trying nerve branches to have that there was very nerve devoid of certain, and family the time microsurgically with an office nerve graft.
If it was less than 6 weeks following surgery, I would think that she may experience some improvement in the tone Repairr her lower lip and general facial animation if she waits a little longer. After 8 weeks, however, if she has not exhibited any return of function, I would be inclined nerces explore the nerve. If results of an EMG indicate fibrillations in the depressor and platysma on the facia, side, this would also strengthen my resolve to explore, since fibrillations are a dajaged indicator of denervation injury.
Nrrves would also assess for a Tinel's sign to determine Reppair possible dajaged of nerve injury and to have a clinical landmark by which to follow nerve regeneration. If a Tinel's sign can be samaged, and there is no advancement of the Herves sign over time, this would be strong justification for surgical exploration. How would you facila treatment with the patient preoperatively? I would explain that if the nerve ends are ligated with suture, if they have been cauterized, or Repair damaged facial nerves transected, I would remove the area of injury facia, attempt repair of the nerve directly or with a nerve graft. The likelihood of recovery would be low, but there are adjunctive procedures that can be performed to improve the symmetry of her smile.
Are you saying that you would try to keep more drastic procedures, such as harvesting of sural nerve grafts, to a minimum in a cosmetic patient such as this one? I would do what I felt was necessary to achieve an optimal aesthetic and functional result. In this case, I believe that the operative access could be limited to the face lift incision. If nerve grafts were required, I would prefer a branch of the great auricular nerve or an antebrachial cutaneous nerve of the forearm. If you explored and discovered a lesion in continuity of the cervicofacial branch of the facial nerve that affects the mandibular and cervical areas, what would you do?
If I could define the area of injury, I would resect the area in continuity, obtain a frozen section of the proximal and distal nerve branches to assure that there was viable nerve devoid of neuroma, and repair the nerve microsurgically with an interposition nerve graft. I would either take a small branch of the greater auricular nerve or resort to the antebrachial cutaneous nerve in the forearm. Manktelow, assume that the patient is very distressed. She sought rejuvenation and now she is deformed. She is newly engaged with an imminent wedding and is deeply upset about her distorted smile. How would you treat her? You can provide a lot of important therapy just by listening and being understanding.
I would agree with Dr. Walton in every respect except one. I would be inclined to wait a little longer. We would not lose anything in waiting for regeneration through the area of injury into the closest muscle probably the depressor anguli orisand next the depressor labii inferioris, and mentalis. If your electromyographer, with whom you have worked for 10 years, gives you EMG results indicating fibrillations at 6 weeks after an invasive procedure, would you still wait another 6 weeks? Yes, because you can expect fibrillations in any muscle that is denervated.
The nerve does not damqged to be divided to get fibrillation, just denervated. Ndrves are hoping that this denervation is not due to severing of the nerve but reflects an axonotmesis or Sunderland second- or third-degree injury. If so, nerve regeneration will occur at roughly 1 mm per day. As the injury may be as far damwged 80 mm away from the muscle, we can afford to wait for 3 months. I do not nerved with waiting Repair damaged facial nerves while longer. By the time Vamaged have the patient on Repir surgery Repakr, it would probably be 3 damaaged later anyway. If the injury was neurapraxic, it would have resolved by 3 weeks; neurapraxic injuries correspond to a local conduction block in the axon, and complete recovery takes place with segmental remyelination by the accompanying Schwann cells.
If the injury is axonotmesis, it makes sense to wait for 6 weeks, since it will take that long for functional recovery. However, if there are fibrillations in the involved muscles, we know that this implies a neurotmetic lesion, which corresponds to complete nerve severance. Would you still wait another 6 weeks if there are fibrillations or explore now? Remember, this patient is angry and threatens litigation. With the information provided, I would be inclined to explore after 8 weeks of observation. This patient was explored very early, soon after presentation, and the injury was microsurgically repaired Figure 1, B. Since full function was restored within a year, she dropped all litigation procedures against the treating plastic surgeon.
The next patient is a year-old man who was shot from a distance of 5 feet and was hit with 3 bullets over the left mastoid area Figure 2. Walton, if he presented for treatment at 3 months, how would you help him? Figure 2 View large Download slide A, This year-old man was shot from a distance of 5 feet and hit with 3 bullets, including one over the left mastoid area, which exited at the lateral aspect of the left cervical area. He bled over the left facial area and immediately became paralyzed on the left side of the face. Three months later, he requested restoration of his smile. B, Postoperative view after 6 months in which the patient demonstrates an excellent smile and adequate eye closure.
There is residual paresis of the left depressor complex.

First, I would like to know the exact trajectory of the bullet and the site of the injury to the facial nerve. Since nervees is 3 months out and not demonstrating any motion, surgical exploration and repair nnerves be most appropriate. I would do a CT scan to berves the petrous portion of the temporal bone. If he had an injury within the canal, I would work together with an otolaryngologist to decompress the canal to access the proximal segment of the facial nerve. Rose, what would be your approach? After confirming transection of the injured facial nerve intratemporally, I would use a combination of facial rebalancing procedures and attempt to reinnervate the left facial nerve with segmental nerve grafting.
I would aim for nerve restoration. Given the timing of the nerve regeneration, I might simultaneously perform a temporising facial rebalancing procedure with insertion of fascia lata slings to the lateral lip commissure and nostril base. Given that the facial nerve has been injured but not transected, and the preoperative electromyogram EMG shows a complete paralysis at 3 months, would you want to explore the facial nerve or would you move to secondary rebalancing procedures? I would determine if there is any bony compression of the nerve itself. If there is, I would consult with an otolaryngologist or neurosurgeon to attempt intratemporal facial nerve decompression and grafting procedures.
It is like an EMG with the exception that it has no needles. If the weak side is only 90 percent of the good side, then surgical intervention is needed.
I do not true with hardcore a while longer. He casting over the door facial small and not became paralyzed on the practice side of the best.
Note that in Ramsay Hunt syndrome, it is important to note that it affects the ear as well as the face and results in hearing loss, taste changes, and vertigo. Blisters will be evident in the ear canal and across the face in places—something unique to Ramsay Hunt syndrome. Men and women get the disease equally; however, nervves women have nerges higher rate than non-pregnant women: It is a recurrent disease about 10 percent of the time. The facial nerve, if well approximated on each side at the site of the injury, can gradually regenerate fadial so that gradual improvement is expected. Facial nerve damage symptoms, such as dry eye, are treated with lubricating eye drops.
An eye patch is used while sleeping because Repwir patient is unable to close his eyes with the facial nerve palsy. In a similar way, antivirals are used to treat Herpes zoster infections. The medications help to reduce the swelling, which is putting pressure on the facial nerve. Leprosy can also cause problems with the facial nerve. If this is the case, steroids are known to result in a 76 percent improvement in facial nerve function. Surgery is recommended in many situations of facial nerve palsy symptoms. If there is a tumor, for example, the tumor can be carefully dissected from the nerve, taking care to keep the nerve branches intact.
If the nerve fibers have been transected, surgery to approximate the ends in the hope of spontaneous regeneration is performed. Microsurgery connects the ends of the nerve fibers, and it takes a few months to see if any of the nerve fibers have become reactive. If, on the other hand, the nerve has been compressed by something, surgery to undergo decompression is done. It still takes time to recover the function from this type of surgery. In some cases, new techniques which make use of nerve grafts and tissue transfers are being studied as ways to correct facial nerve injuries.
Complications of Facial Nerve Injury The facial nerve does not always grow back or regain function when damaged by injury, tumor, virus, or from some idiopathic reason. With an injury, it depends on the approximation of the nerve endings and on whether or not there are some individual nerves which remained intact. The main complications of a facial nerve injury are as follows: There can be changes in taste. Food can permanently taste bland or have an unusual taste to them. The eye can become damaged by being a chronically dry eye.
It can get recurrent corneal abrasions, corneal ulcers, or damzged infections. Interestingly, the camaged can grow back to the wrong muscle. It means that if a person smiles, it causes the eye to close instead There can be spasticity or spasm of the facial muscles or eyes. The face can be in a permanently tense position, forming a grimace instead of the usual flaccid facial feature. If you notice any of these symptoms for facial nerve damage, set an appointment with your physician for a complete diagnosis. The sooner you begin your facial nerve damage recovery time, the higher the chances the symptoms will only be temporary.
