TY - JOUR. T1 - Electrical stimulation facilitates rat facial nerve recovery from a crush injury. AU - Lal, Devyani. AU - Hetzler, Laura T.. AU - Sharma, Nijee. AU - Wurster, Robert D.. AU - Marzo, Sam J.. AU - Jones, Kathryn J.. AU - Foecking, Eileen M.. PY - 2008/7. Y1 - 2008/7. N2 - Objective: To study the effect of electrical stimulation on accelerating facial nerve functional recovery from a crush injury in the rat model. Study Design: Experimental. Method: The main trunk of the right facial nerve was crushed just distal to the stylomastoid foramen, causing right-sided facial paralysis in 17 Sprague-Dawley rats. An electrode apparatus was implanted in all rats. Nine rats underwent electrical stimulation and eight were sham stimulated until complete facial nerve recovery. Facial nerve function was assessed daily by grading eyeblink reflex, vibrissae orientation, and vibrissae movement. Results: An electrical stimulation model of the rat facial nerve following axotomy was established. The ...
The facial nerve is the seventh cranial nerve, or simply cranial nerve VII. It emerges from the brainstem between the pons and the medulla, controls the muscles of facial expression, and functions in the conveyance of taste sensations from the anterior two-thirds of the tongue and oral cavity. It also supplies preganglionic parasympathetic fibers to several head and neck ganglia. The facial and intermediate nerves can be collectively referred to as the nervus intermediofacialis. The path of the facial nerve can be divided into six segments. intracranial (cisternal) segment meatal segment (brainstem to internal auditory canal) labyrinthine segment (internal auditory canal to geniculate ganglion) tympanic segment (from geniculate ganglion to pyramidal eminence) mastoid segment (from pyramidal eminence to stylomastoid foramen) extratemporal segment (from stylomastoid foramen to post parotid branches) The motor part of the facial nerve arises from the facial nerve nucleus in the pons while the ...
Objective: This literature review analysed facial nerve management strategies in jugular paraganglioma surgery and discusses the tumour resection rate and the facial nerve outcome associated with each technique. Methods: A retrospective review of PubMed and Medline articles on the surgical treatments for jugular paraganglioma was performed. Tumour resection rates and post-operative facial nerve function after non-rerouting, short anterior rerouting and long anterior rerouting approaches were evaluated for each article. Results: A total of 15 studies involving a total of 688 patients were included. Post-operative facial nerve function was similar after non-rerouting and short anterior rerouting approaches (p = 0.169); however, both of these techniques had significantly better post-operative facial nerve outcomes compared with long anterior rerouting (p , 0.001 and p = 0.001, respectively). The total tumour removal rate was significantly higher for long anterior rerouting than with the ...
Causes of facial nerve damage are injury to the seventh cranial nerve. Symptoms of facial nerve damage are facial palsy and partial loss of sensation of taste.
The facial nerve is necessary for our ability to eat, speak, and make facialgestures. To perform these vital functions, the nerve must accurately navigate from the hindbrain to the correct muscles during embryonic development. In the development of the facial nerve, both the cell bodies and the axons undergo specific migration patterns to assemble central neuron patterns and peripheral nerve projections to target muscles. Our goal in this study was to define the molecular signals by which the facial cell bodies and their axons correctly make this long journey. By analyzing facial neuron migration patterns in mouse embryos carrying mutations in the chemorepulsive receptors Robo1 and Robo2, we found that these proteins are necessary for guiding the cell bodies and axons of the branchiomotor aspect of the facial nerve. In mutants, most axons do not make it to their motor exit point, and instead project into the floorplate. Mutant axons thatexit the hindbrain appear misguided, with some branches ...

Now, I have not gone into detail much online, other than a whittled-down list of folks on my Facebook page who are my prayer warriors, close friends and family members. But I had major ear surgery last week at Fort Lewis, Washington. I had a growth that distorted my eardrum, destroyed much of my temporal bone all the way up to my brain, began to expose my facial nerve, damaged a taste nerve, and destroyed two of the three bones needed for hearing. I now have a new reconstructed eardrum, no disease, and my facial nerve, perilously close to being exposed and damaged, is getting some steroids for strength and protection. I still have hearing in my ear--its all sensorineural, as those parts are still in working order. My hearing loss will be able to be fixed next year (should the disease not return) with the insertion of a titanium implant replacing the two destroyed hearing bones, connecting my new eardrum to the stapes bone ...

He is at the beginning and the end of it. But to be more specific, people have prayed for a speedy recovery. One prayer requested of God that when the surgeons got in there, they would, say "Hey! Somebody has been in here before us." Well, the angiogram found almost nothing to embolize. This made it much easier to work on the tumor. What happened to the blood supply that grew that tumor so big? God. Secondly, the MRI shows with obvious detail that the tumor had a "sticky" character. It wasnt sticky; should have been, but it wasnt. Why not? God. The tumor has invaded the cranial nerves responsible for facial motor function, swallowing and some others that have been mentioned in the pages of this blog somewhere. Removing the tumor from them would be destructive and require weeks and weeks of rehabilitation. It was not necessary to remove the tumor from around those nerves, so Tracy has pretty good function all around. I have explained before that enough of the tumor was removed that what is left ...
Two central nervous system origins are customarily ascribed to each cranial nerve: 1.) Superficial origins are from the surface of the central nervous system, while 2.) Deep origins are from cell bodies and nuclei within the central nervous system (30). The general location and approximate number of rootlets of origin for cranial nerves have been well described in standard anatomy texts (31). Contrariwise, descriptions of the interconnections of these rootlets are not readily found. Bischoff published such a study in 1865 (32). Fragmentary descriptions of individual nerve connections often have been found only scattered throughout the literature. For example, Hovelaque (33) quotes earlier authors Hirshfield and Sappy in their descriptions of variations in interconnections of the ansa of von Haller, also called the nerve of Jacobson, lying between the hypoglossal and facial nerves. As another example of a variable interconnection observed in our laboratory, in one subject, the rootlets of the ...
Surgery on Facial Scars. When the skin is in the process of recovering from an injury, whether the result of an accident, tumor, surgery, a burn, or acne, scarring will occur wherever multiple layers of the skin have been affected. Once a scar forms, it is permanent but may be made less visible or relocated surgically.. With very few exceptions most people are self-conscious about facial scars. Some people may also experience diminished functioning of the eyes, mouth, or nose due to scarring. If youve wondered how facial scar revision could improve your appearance, your self-confidence, or your level of facial functioning, you need to know how scar revision works and what you can expect from this procedure. This pamphlet can address many of your and provide you the information to begin considering facial scar revision surgery.. A person considering facial scar revision must understand that there is no way to remove scars completely. The goal is to improve the appearance of the scar either by ...

One of the major complications of a peripheral facial nerve palsy (PFP) is the occurrence of corneal ulceration due to lagophthalmos-that is, incomplete closure of the affected eyelid. It is widely accepted that lagophthalmos after PFP is directly caused by paresis of the orbicularis oculi muscle (eyelid closure muscle). Yet, some of the signs and symptoms, which may be observed in patients with PFP cannot be explained by paresis of the orbicularis oculi muscle alone. First of all, gentle closure of the eyelid, as for example occurs when a person falls into sleep, is completely brought about by inhibition of the tonic activity of the levator palpebrae muscle (eyelid opener muscle).1 Secondly, upward and downward saccadic lid movements, accompanying saccadic eye movements, are mainly due to modification of the tonic activity of the levator palpebrae muscle. Finally, the downward and upward smooth pursuit movements of the lids are again secondary to alterations in the level of activity of the ...

Imaging of facial nerve schwannomas includes both MRI and CT. On noncontrast temporal bone CT, the findings include a tubular soft tissue mass along the course of the facial nerve with enlargement of the facial nerve canal. The bony margins are usually smooth and benign-appearing. On MRI, these lesions have intermediate to low signal intensity on T1-weighted imaging and high signal intensity on T2-weighted imaging. Following the administration of intravenous gadolinium, facial nerve schwannomas enhance homogenously. The differential diagnosis includes normal intratemporal facial nerve enhancement, Bells palsy, facial nerve hemangioma, and facial nerve perineural parotid malignancy. Based on clinical presentation, facial nerve schwannoma can be distinguished from Bells palsy and a hemangioma by a more gradual onset of facial nerve paralysis vs an acute onset in these other entities. Normal facial nerve enhancement is asymptomatic, and facial nerve perineural parotid malignancy is associated ...

Anastomoses between the transverse cervical cutaneous nerve and the cervical branch of facial nerve are regularly present. The anatomic locations of these anastomoses were poorly documented in the literature. During regular dissection, we came across two of such anastomoses: one of the two anastomoses was identified posterior to submandibular gland, and the other was noted within the parenchyma of the parotid gland. Prior knowledge of anatomic locations of these anastomoses is clinically important as it allows a method for identification and preservation of the cervical branch of the facial nerve as well as a starting point for retrograde facial nerve dissections. In addition, few terminal nerve endings of transverse cervical cutaneous nerve were seen along the retromandibular vein, ducts and some were penetrating the interlobular septa of parotid gland. The functional significance of anatomic variations of its nerve terminal ends deep in the gland is yet to be evaluated.. ...
Bells palsy was named after a Scottish doctor, Sir Charles Bell, who studied the two facial nerves that direct how the face moves. You have one facial nerve for each side of your face. These nerves send messages from the brain to the face. Through these messages, the facial nerves control the muscles of your face, forehead, and neck.. Facial nerves control the expressions you make - like raising your eyebrows, squeezing your eyes shut, or smiling. Each facial nerve starts in the brain, goes through the skull in a narrow tube of bone, and exits the skull behind the ear. From there, it splits into smaller branches of nerves that attach to the muscles of the face, neck, and ear. Other small nerve branches run to the glands that make saliva, the glands that make tears, and the front of the tongue.. Remember that narrow tube of bone that holds the facial nerve? When the facial nerve is infected or damaged, it swells up and presses against the inside of that bony tube. The nerve gets squashed, and it ...
ASPN 2020 Abstracts: Tissue Engineered Nerve Grafts Facilitate Muscle Reinnervation Following Long Gap Facial Nerve Injury in Swine
The lesser petrosal nerve (also known as the small superficial petrosal nerve) is the General visceral efferent (GVE) component of the glossopharyngeal nerve (CN IX), carrying parasympathetic pre-ganglionic fibers from the tympanic plexus to the parotid gland. It synapses in the Otic ganglion, from where the post-ganglionic fibers emerge. After arising in the tympanic plexus, the lesser petrosal nerve passes forward and then through the hiatus for lesser petrosal nerve on the anterior surface of the petrous part of the temporal bone into the middle cranial fossa. It travels across the floor of the middle cranial fossa, then exits the skull via foramen ovale to reach the infratemporal fossa. The fibres synapse in the otic ganglion, and post-ganglionic fibres then travel briefly with the auriculotemporal nerve (a branch of V3) before entering the body of the parotid gland. The lesser petrosal nerve will distribute its parasympathetic post-ganglionic (GVE) fibers to the parotid gland via the ...
MR images of the intratemporal portion of the facial nerve were obtained with surface coils using a 0.3-T permanent magnet whole-body imaging system. Various 20FT spin-echo pulse sequences were used to produce 5-mm thick sections with 0.5-mm pixels on a 512 × 512 acquisition matrix. The MR images from normal volunteers were correlated with cryosection specimens of three fresh human cadavers. The seventh nerve was followed in the internal auditory and fallopian canal and through temporal bone to the stylomastoid foramen. The entire labyrinthine, tympanic, and mastoid portions, as well as the geniculate ganglion, could be shown with appropriate scan planes. MR produces excellent images of the facial nerve with high-contrast resolution. Unlike CT, no beam-hardening artifact from the temporal bone is apparent. MR should be a sensitive study for the evaluation of intratemporal facial nerve disease.. ...
Facial Nerve Neuroma. One of the less common benign tumors of the middle ear is the facial neuroma, a tumor of the facial nerve. As it expands, it can put pressure on the facial nerve and cause facial paralysis. These tumors are clinically important.. Excision of the facial nerve neuroma may require removal of a segment of the facial nerve as well as a regrafting of the facial nerve with a nerve taken from another site. Common donor sites include a nerve in the neck or a portion of the nerve in the leg.. At surgery, the tumor is completely removed and the two separated segments are reconnected by placing the new segment of nerve graft between these ends. Regrowth of normal nerve endings through the nerve graft will take at least six months to begin, and 12 to 18 months to see the full recuperation of the nerve. In this setting, facial expression is never completely normal, but good results can be obtained.. Cholesterol Granulomas. Cholesterol granulomas are less common and are not really tumors. ...

As the nerve exits the stylomastoid foramen, it gives off a sensory branch that supplies part of the external acoustic meatus and tympanic membrane. It then passes between the posterior belly of the digastric muscle and the stylohyoid muscle and enters the parotid gland. Lying between the deep and superficial lobes of the gland the nerve divides into to main branches at the pes anserinus (Latin: duck foot) - a superior temporofacial and and inferior cervicofacial branches. From the anterior border of the gland, five branches emerge; temporal, zygomatic, buccal, mandibular (marginal) and cervical (see facial nerve branches mnemonic here). The temporal branch runs with the superficial musculoaponeurotic system (SMAS) over the zygomatic arch. This branch is at risk during surgery in this region. To avoid damage procedures should be deep to the SMAS (e.g. zygomatic fracture repairs). The mandibular branch, in 80% of cases, runs along the lower border of the mandible (thus also referred to as ...

Facial palsy is a common problem that involves the weakness or paralysis of any of the muscles served by the facial nerve, especially those around the eye and to the mouth. The pathway of the facial nerve is long and rather convoluted, so there are a number of causes that may result in facial nerve paralysis.
Facial branchiomotor (fbm) neurones undergo a complex migration in the segmented mouse hindbrain. They are born in the basal plate of rhombomere (r) 4, migrate caudally through r5, and then dorsally and radially in r6. To study how migrating cells adapt to their changing environment and control their pathway, we have analysed this stereotyped migration in wild-type and mutant backgrounds. We show that during their migration, fbm neurones regulate the expression of genes encoding the cell membrane proteins TAG-1, Ret and cadherin 8. Specific combinations of these markers are associated with each migratory phase in r4, r5 and r6. In Krox20 and kreisler mutant mouse embryos, both of which lack r5, fbm neurones migrate dorsally into the anteriorly positioned r6 and adopt an r6-specific expression pattern. In embryos deficient for Ebf1, a gene normally expressed in fbm neurones, part of the fbm neurones migrate dorsally within r5. Accordingly, fbm neurones prematurely express a combination of markers ...

Lorraine, renowned for her work in facial nerve palsy, co-founded and chaired Facial Therapy Specialists UK until last December. When checking the inside of a patients mouth and cheek following complete facial nerve palsy, she noticed that when the cheek was stretched, there was a subsequent spasm of the muscles of facial expression - even though they had no voluntary or spontaneous movement. Lorraine shared this observation with Professor Jonathan Cole, a neurophysiologist, at the eleventh International Facial Nerve Symposium in Rome in 2009.
