To describe the management of traumatic neuroma of the facial nerve in a child and literature review. Sixteen-month-old male subject. Radiological imaging and surgery. Facial nerve function. The patient presented at 16 months with a right facial palsy and was found to have a right facial nerve traumatic neuroma. A transmastoid, middle fossa resection of the right facial nerve lesion was undertaken with a successful facial nerve-to-hypoglossal nerve anastomosis. The facial palsy improved postoperatively. A traumatic neuroma should be considered in an infant who presents with facial palsy, even in the absence of an obvious history of trauma. The treatment of such lesion is complex in any age group but especially in young children. Symptoms, age, lesion size, growth rate, and facial nerve function determine the appropriate management.

The hypoglossal facial anastomosis (HFA) is the gold standard for facial reanimation in patients with severe facial nerve palsy. The major drawbacks of the classic HFA technique are lingual morbidities due to hypoglossal nerve transection. The side-to-end HFA is a modification of the classic technique with fewer tongue-related morbidities. In this study we compared the outcome of the classic end-to-end and the direct side-to-end HFA surgeries performed at our center in regards to the facial reanimation success rate and tongue-related morbidities. Twenty-six successive cases of HFA were enrolled. In 9 of them end-to-end anastomoses were performed, and 17 had direct side-to-end anastomoses. The House-Brackmann (HB) and Pitty and Tator (PT) scales were used to document surgical outcome. The hemiglossal atrophy, swallowing, and hypoglossal nerve function were assessed at follow-up. The original pathology was vestibular schwannoma in 15, meningioma in 4, brain stem glioma in 4, and other pathologies in 3. The mean interval between facial palsy and HFA was 18 months (range: 0-60). The median follow-up period was 20 months. The PT grade at follow-up was worse in patients with a longer interval from facial palsy and HFA (P value: 0.041). The lesion type was the only other factor that affected PT grade (the best results in vestibular schwannoma and the worst in the other pathologies group, P value: 0.038). The recovery period for facial tonicity was longer in patients with radiation therapy before HFA (13.5 vs. 8.5 months) and those with a longer than 2-year interval from facial palsy to HFA (13.5 vs. 8.5 months). Although no significant difference between the side-to-end and the end-to-end groups was seen in terms of facial nerve functional recovery, patients from the side-to-end group had a significantly lower rate of lingual morbidities (tongue hemiatrophy: 100% vs. 5.8%, swallowing difficulty: 55% vs. 11.7%, speech disorder 33% vs. 0%). With the side-to-end HFA

The hypoglossal-facial-anastomosis is the most often applied procedure for the reanimation of a long lasting peripheral facial nerve paralysis. The use of an interposition graft and its end-to-side anastomosis to the hypoglossal nerve allows the preservation of the tongue function and also requires two anastomosis sites and a free second donor nerve. We describe the modified technique of the hypoglossal-facial-jump-anastomosis without an interposition and present the first results. Retrospective case study. We performed the facial nerve reconstruction in five patients. The indication for the surgery was a long-standing facial paralysis with preserved portion distal to geniculate ganglion, absent voluntary activity in the needle facial electromyography, and an intact bilateral hypoglossal nerve. Following mastoidectomy, the facial nerve was mobilized in the fallopian canal down to its bifurcation in the parotid gland and cut in its tympanic portion distal to the lesion. Then, a tensionless end-to-side suture to the hypoglossal nerve was performed. The facial function was monitored up to 16 months postoperatively. The reconstruction technique succeeded in all patients: The facial function improved within the average time period of 10 months to the House-Brackmann score 3. This modified technique of the hypoglossal-facial reanimation is a valid method with good clinical results, especially in cases of a preserved intramastoidal facial nerve. Level 4.

Iatrogenic injuries to cranial nerves, half of which affect the hypoglossal nerve, occur in up to 20% of surgical procedures involving the neck. The risk of injury could be minimized by in-depth knowledge of its positional and relational anatomy. Forty-one hypoglossal nerves were dissected from cadaveric specimens and positions described in relation to the internal carotid artery (ICA), external carotid artery (ECA), carotid bifurcation, mandible, hyoid bone, mastoid process, and the digastric tendon. The distance of the nerve from where it crossed the ICA and ECA to the carotid bifurcation was 29.93 (±5.99) mm and 15.19 (±6.68) mm, respectively. The point where it crossed the ICA was 12.24 (±3.71) mm superior to the greater horn of hyoid, 17.16 (±4.40) mm inferior to the angle of the mandible, and 39.08 (±5.69) mm from tip of the mastoid. The hypoglossal nerve loop was inferior to the digastric tendon in 73% of the cases. The hypoglossal nerves formed high loops in this study population. Caution should be exercised during surgical procedures in the neck. The study also revealed that the mastoid process is a reliable fixed landmark to locate the hypoglossal nerve.

Schwannoma of the hypoglossal nerve is rare. This case report documents an atypical abnormality of the cervical vestibular evoked myogenic potential (cVEMP) in a patient with schwannoma of the hypoglossal nerve. The observed abnormality was attributed to the proximity of the hypoglossal nerve to the spinal accessory nerve in the medullary cistern and base of the skull. To report cVEMP abnormality in a patient with hypoglossal nerve schwannoma and provide an anatomical correlation for this abnormality. Case report. A 44-yr-old woman. Pure-tone and speech audiometry, tympanometry, acoustic stapedial reflex, auditory brainstem response, and cVEMP testing were performed. The audiological test results were normal except for the absence of cVEMP on the lesion side (right). A cVEMP abnormality indicating a compromised spinal accessory nerve was observed in a patient with hypoglossal nerve schwannoma. This case report highlights the importance of recording cVEMP in relevant neurological conditions and provides clinical proof for the involvement of the spinal accessory nerve in the vestibulocollic reflex pathway.

Full Text Available Aesthetic and functional complications caused by general anesthesia have been rarely described after aesthetic surgery. We report a case of unilateral right hypoglossal nerve paralysis following the use of a cuffed endotracheal airway in a 24-year-old woman undergoing aesthetic breast surgery. Neurological examination and magnetic resonance imaging of the head failed to provide additional insights into the cause of the nerve injury. Postoperatively, the patient was carefully monitored and made a full recovery within 2 weeks without any pharmacological treatment. The transient hypoglossal nerve paralysis seemed to be due to neuropraxia. In this patient, we postulate that the right hypoglossal nerve was compressed between the endotracheal tube cuff and the hyoid bone, which was inflated with 30 cm H 2 O. Patients undergoing aesthetic surgery must be appropriately and adequately informed that postoperative aesthetic and functional deficits can occur due to anesthesia as well as the surgery.

Swallowing pressure generation is important to ensure safe transport of an ingested bolus without aspiration or leaving residue in the pharynx. To clarify the mechanism, we measured swallowing pressure at the oropharynx (OP), upper esophageal sphincter (UES), and cervical esophagus (CE) using a specially designed manometric catheter in anesthetized rats. A swallow, evoked by punctate mechanical stimulation to the larynx, was identified by recording activation of the suprahyoid and thyrohyoid muscles using electromyography (EMG). Areas under the curve of the swallowing pressure at the OP, UES, and CE from two trials indicated high intrasubject reproducibility. Effects of transecting the hypoglossal nerve (12N) and recurrent laryngeal nerve (RLN) on swallowing were investigated. Following bilateral hypoglossal nerve transection (Bi-12Nx), OP pressure was significantly decreased, and time intervals between peaks of thyrohyoid EMG bursts and OP pressure were significantly shorter. Decreased OP pressure and shortened times between peaks of thyrohyoid EMG bursts and OP pressure following Bi-12Nx were significantly increased and longer, respectively, after covering the hard and soft palates with acrylic material. UES pressure was significantly decreased after bilateral RLN transection compared with that before transection. These results suggest that the 12N and RLN play crucial roles in OP and UES pressure during swallowing, respectively. We speculate that covering the palates with a palatal augmentation prosthesis may reverse the reduced swallowing pressure in patients with 12N or tongue damage by the changes of the sensory information and of the contact between the tongue and a palates. NEW & NOTEWORTHY Hypoglossal nerve transection reduced swallowing pressure at the oropharynx. Covering the hard and soft palates with acrylic material may reverse the reduced swallowing function caused by hypoglossal nerve damage. Recurrent laryngeal nerve transection reduced upper

2017-01-01

Schwannomas of the descending loop of the hypoglossal nerve are very rare. They are slow-growing tumors that may masquerade a carotid body tumor. A 60-year-old female was referred for a latero-cervical mass appearing as a chemodectoma at CT-scan. At operation, a 2cm mass arising from the descending loop of the hypoglossal nerve was resected en bloc with the loop itself and a functional lymphadenectomy was associated. Post-operative course was uneventful and the patient is free from disease recurrence at one year follow-up. En bloc resection remains the real curative treatment of Schwannomas, ensuring unlimited freedom from disease, although causing functional impairment which may be significant. Nonetheless recurrence should be prevented as, beside requiring reintervention, it may harbor a malignant evolution towards sarcoma. Schwannomas of the descending lop of the hypoglossal nerve may masquerade a chemodectoma of the carotid bifurcation and can be curatively resected without any functional impairment.

We report the characteristics, diagnosis and treatment of dural arteriovenous fistula (DAVF) of the hypoglossal canal in nine patients with this relatively rare vascular disorder. Of 248 patients with intracranial DAVFs managed at our institution, nine patients (3.6%; four men, five women; mean age 62 years) were diagnosed with hypoglossal canal DAVF. We investigated patient characteristics with respect to clinical symptoms, neuroradiological findings, efficacy and complications related to endovascular treatment. Seven patients had experienced head injury. All patients presented with pulsatile tinnitus. One patient displayed ipsilateral hypoglossal nerve palsy before treatment. MR angiography showed a 'magic wand' appearance between the affected hypoglossal canal and the internal jugular vein in four patients. Angiography demonstrated an AV fistula on the medial aspect of the superior jugular bulb, mostly arising from the bilateral occipital, ascending pharyngeal and vertebral arteries with drainage to the internal jugular vein via the anterior condylar vein. Contralateral carotid injection accurately clarified the shunting point. Five patients underwent endovascular treatment: transarterial embolization (TAE; n=2), transvenous embolization (TVE; n=2), and TAE/TVE (n=1). Complete shunt obliteration was achieved in four patients and shunt reduction in one. The remaining four patients were treated conservatively and the shunt had disappeared at follow-up. Postoperative hypoglossal nerve palsy occurred in one patient after TVE, possibly due to coil overpacking. The incidence of hypoglossal canal DAVF was not very low in our series. Contralateral carotid injection is an essential examination to provide an accurate diagnosis. TVE should be considered when access is available, although TAE is also appropriate for shunt reduction.

Four cases of schwannoma originating from the lower cranial nerves are presented. Case 1 is a schwannoma of the vagus nerve in the parapharyngeal space. The operation was performed by the transcervical approach. Although the tumor capsule was not dissected from the vagus nerve, hoarseness and dysphagia happened transiently after the operation. Case 2 is a schwannoma in the jugular foramen. The operation was performed by the infralabyrinthine approach. Although only the intracapsular tumor was enucleated, facial palsy, hoarseness, dysphagia and paresis of the deltoid muscle occurred transiently after the operation. The patient's hearing had also slightly deteriorated. Case 3 is a dumbbell-typed schwannoma originating from the hypoglossal nerve. The hypoglossal canal was markedly enlarged by the tumor. As the hypoglossal nerves were embedded in the tumor, the tumor around the hypoglossal nerves was not resected. The tumor was significantly enlarged for a while after stereotactic irradiation. Case 4 is an intracranial cystic schwannoma originating from the IXth or Xth cranial nerves. The tumor was resected through the cerebello-medullary fissure. The tumor capsule attached to the brain stem was not removed. Hoarseness and dysphagia happened transiently after the operation. Cranial nerve palsy readily occurs after the removal of the schwannoma originating from the lower cranial nerves. Mechanical injury caused by retraction, extension and compression of the nerve and heat injury during the drilling of the petrous bone should be cautiously avoided.

Injury to distal portion of posterior cord of brachial plexus leads to palsy of radial and axillary nerves. Symptoms are usually motor deficits of the deltoid muscle; triceps brachii muscle; and extensor muscles of the wrist, thumb, and fingers. Tendon transfers, nerve grafts, and nerve transfers are options for surgical treatment of proximal radial nerve palsy to restore some motor functions. Tendon transfer is painful, requires a long immobilization, and decreases donor muscle strength; nevertheless, nerve transfer produces promising outcomes. We present a patient with proximal radial nerve palsy following a blunt injury undergoing triple nerve transfer. The patient was involved in a motorcycle accident with complete palsy of the radial and axillary nerves. After 6 months, on admission, he showed spontaneous recovery of axillary nerve palsy, but radial nerve palsy remained. We performed triple nerve transfer, fascicle of ulnar nerve to long head of the triceps branch of radial nerve, flexor digitorum superficialis branch of median nerve to extensor carpi radialis brevis branch of radial nerve, and flexor carpi radialis branch of median nerve to posterior interosseous nerve, for restoration of elbow, wrist, and finger extensions, respectively. Our experience confirmed functional elbow, wrist, and finger extensions in the patient. Triple nerve transfer restores functions of the upper limb in patients with debilitating radial nerve palsy after blunt injuries. Copyright © 2017 Elsevier Inc. All rights reserved.

Full Text Available Third nerve paralysis has been known to be associated with a wide spectrum of presentation and other associated factors such as the presence of ptosis, pupillary involvement, amblyopia, aberrant regeneration, poor bell′s phenomenon, superior oblique (SO overaction, and lateral rectus (LR contracture. Correction of strabismus due to third nerve palsy can be complex as four out of the six extraocular muscles are involved and therefore should be approached differently. Third nerve palsy can be congenital or acquired. The common causes of isolated third nerve palsy in children are congenital (43%, trauma (20%, inflammation (13%, aneurysm (7%, and ophthalmoplegic migraine. Whereas, in adult population, common etiologies are vasculopathic disorders (diabetes mellitus, hypertension, aneurysm, and trauma. Treatment can be both nonsurgical and surgical. As nonsurgical modalities are not of much help, surgery remains the main-stay of treatment. Surgical strategies are different for complete and partial third nerve palsy. Surgery for complete third nerve palsy may involve supra-maximal recession - resection of the recti. This may be combined with SO transposition and augmented by surgery on the other eye. For partial third nerve, palsy surgery is determined according to nature and extent of involvement of extraocular muscles.

2017-07-01

Parkinson's disease (PD) patients apart from motor dysfunctions exhibit respiratory disturbances. Their mechanism is still unknown and requires investigation. Our research was designed to examine the activity of phrenic (PHR) and hypoglossal (HG) nerves activity during a hypoxic respiratory response in the 6-hydroxydopamine (6-OHDA) model of PD. Male adult Wistar rats were injected unilaterally with 6-OHDA (20μg) or the vehicle into the right medial forebrain bundle (MFB). Two weeks after the surgery the activity of the phrenic and hypoglossal nerve was registered in anesthetized, vagotomized, paralyzed, and mechanically ventilated rats under normoxic and hypoxic conditions. Lesion effectiveness was confirmed by the cylinder test, performed before the MFB injection and 14days after, before the respiratory experiment. 6-OHDA lesioned animals showed a significant increase in normoxic inspiratory time. Expiratory time and total time of the respiratory cycle were prolonged in PD rats after hypoxia. The amplitude of the PHR activity and its minute activity were increased in comparison to the sham group at recovery time and during 30s of hypoxia. The amplitude of the HG activity was increased in response to hypoxia in 6-OHDA lesioned animals. The degeneration of dopaminergic neurons decreased the pre-inspiratory/inspiratory ratio of the hypoglossal burst amplitude during and after hypoxia. Unilateral MFB lesion changed the activity of the phrenic and hypoglossal nerves. The altered pre-inspiratory hypoglossal nerve activity indicates modifications to the central mechanisms controlling the activity of the HG nerve and may explain respiratory disorders seen in PD, i.e. apnea.

Twenty-five patients with 35 cranial nerve palsies were seen at the Fondation Curie during follow-up after radical radiotherapy for head and neck tumors. The twelfth nerve was involved in 19 cases, the tenth in nine, and the eleventh in five; the fifth and second nerves were involved once each and in the same patient. The twelfth nerve was involved alone in 16 patients and the tenth nerve alone in three, with multiple nerves involved in the remaining six patients. The palsy was noted from 12 to 145 months after diagnosis of the tumor. The latency period could be correlated with dose so that the least square fit equation representing NSD vs delay is NSD = 2598--Delay (in months) x 4.6, with a correlation coefficient of -0.58. The distinction between tumor recurrence and radiation-induced nerve palsy is critical. It can often be inferred from the latency period but must be confirmed by observation over a period of time

To investigate the prognostic value of concurrent phrenic nerve palsy for predicting spontaneous motor recovery in neonatal brachial plexus palsy. We reviewed the records of 366 neonates with brachial plexus palsy. The clinical and follow-up data of patients with and without phrenic nerve palsy were compared. Of 366 newborn babies with neonatal brachial plexus palsy, 21 (6%) had concurrent phrenic nerve palsy. Sixteen of these neonates had upper-type palsy and 5 had total-type palsy. Poor spontaneous motor recovery was observed in 13 neonates with concurrent phrenic nerve palsy (62%) and in 129 without concurrent phrenic nerve palsy (39%). Among neonates born via vertex delivery, poor motor recovery was observed in 7 of 9 (78%) neonates with concurrent phrenic nerve palsy and 115 of 296 (39%) without concurrent phrenic nerve palsy. Concurrent phrenic nerve palsy in neonates with brachial plexus palsy has prognostic value in predicting poor spontaneous motor recovery of the brachial plexus, particularly after vertex delivery.

Peripheral nerve involvement in Bell's palsy

Directory of Open Access Journals (Sweden)

J. A. Bueri

1984-12-01

Full Text Available A group of patients with Bell's palsy were studied in order to disclose the presence of subclinical peripheral nerve involvement. 20 patients, 8 male and 12 female, with recent Bell's palsy as their unique disease were examined, in all cases other causes of polyneuropathy were ruled out. Patients were investigated with CSF examination, facial nerve latencies in the affected and in the sound sides, and maximal motor nerve conduction velocities, as well as motor terminal latencies from the right median and peroneal nerves. CSF laboratory examination was normal in all cases. Facial nerve latencies were abnormal in all patients in the affected side, and they differed significantly from those of control group in the clinically sound side. Half of the patients showed abnormal values in the maximal motor nerve conduction velocities and motor terminal latencies of the right median and peroneal nerves. These results agree with previous reports which have pointed out that other cranial nerves may be affected in Bell's palsy. However, we have found a higher frequency of peripheral nerve involvement in this entity. These findings, support the hypothesis that in some patients Bell's palsy is the component of a more widespread disease, affecting other cranial and peripheral nerves.

This paper evaluates the utility of multiplanar reconstructions (MPRs) of three-dimensional (3D) MR angiography data sets in the examination of patients with cranial nerve palsies. The authors hypothesis was that 3D data could be reformatted to highlight the intricate spatial relationships of vessels to adjacent neural tissues by taking advantage of the high vessel-parenchyma contrast in high-resolution 3D time-of-flight sequences. Twenty patients with cranial nerve palsies and 10 asymptomatic patients were examined with coronal T1-weighted and axial T2-weighted imaging plus a gadolinium-enhanced 3D MRA sequence (40/7/15 degrees, axial 60-mm volume, 0.9-mm isotropic resolution). Cranial nerves II-VIII were subsequently evaluated on axial and reformatted coronal and/or sagittal images

Closed temporal bone fractures due to cranial trauma often result in facial nerve injury, frequently inducing incomplete facial paralysis. Conventional hypoglossal-facial nerve end-to-end neurorrhaphy may not be suitable for these injuries because sacrifice of the lesioned facial nerve for neurorrhaphy destroys the remnant axons and/or potential spontaneous innervation. we modified the classical method by hypoglossal-facial nerve "side"-to-side neurorrhaphy using an interpositional predegenerated nerve graft to treat these injuries. Five patients who experienced facial paralysis resulting from closed temporal bone fractures due to cranial trauma were treated with the "side"-to-side neurorrhaphy. An additional 4 patients did not receive the neurorrhaphy and served as controls. Before treatment, all patients had suffered House-Brackmann (H-B) grade V or VI facial paralysis for a mean of 5 months. During the 12-30 months of follow-up period, no further detectable deficits were observed, but an improvement in facial nerve function was evidenced over time in the 5 neurorrhaphy-treated patients. At the end of follow-up, the improved facial function reached H-B grade II in 3, grade III in 1 and grade IV in 1 of the 5 patients, consistent with the electrophysiological examinations. In the control group, two patients showed slightly spontaneous innervation with facial function improved from H-B grade VI to V, and the other patients remained unchanged at H-B grade V or VI. We concluded that the hypoglossal-facial nerve "side"-to-side neurorrhaphy can preserve the injured facial nerve and is suitable for treating significant incomplete facial paralysis resulting from closed temporal bone fractures, providing an evident beneficial effect. Moreover, this treatment may be performed earlier after the onset of facial paralysis in order to reduce the unfavorable changes to the injured facial nerve and atrophy of its target muscles due to long-term denervation and allow axonal

Full Text Available Aims: The aim was to assess the etiology of sixth nerve palsy and on the basis of our data, to formulate a diagnostic algorithm for the management in sixth nerve palsy. Design: Retrospective chart review. Results: Of the 104 neurologically isolated cases, 9 cases were attributable to trauma, and 95 (86.36% cases were classified as nontraumatic, neurologically isolated cases. Of the 95 nontraumatic, isolated cases of sixth nerve palsy, 52 cases were associated with vasculopathic risk factors, namely diabetes and hypertension and were classified as vasculopathic sixth nerve palsy (54.7%, and those with a history of sixth nerve palsy from birth (6 cases were classified as congenital sixth nerve palsy (6.3%. Of the rest, neuroimaging alone yielded a cause in 18 of the 37 cases (48.64%. Of the other 19 cases where neuroimaging did not yield a cause, 6 cases were attributed to preceding history of infection (3 upper respiratory tract infection and 3 viral illnesses, 2 cases of sixth nerve palsy were found to be a false localizing sign in idiopathic intracranial hypertension and in 11 cases, the cause was undetermined. In these idiopathic cases of isolated sixth nerve palsy, neuroimaging yielded no positive findings. Conclusions: In the absence of risk factors, a suggestive history, or positive laboratory and clinical findings, neuroimaging can serve as a useful diagnostic tool in identifying the exact cause of sixth nerve palsy. Furthermore, we recommend an algorithm to assess the need for neuroimaging in sixth nerve palsy.

Full Text Available Objective: The dehiscent facial nerve canal has been well documented in histopathological studies of temporal bones as well as in clinical setting. We describe clinical and radiologic features of a child with recurrent facial nerve palsy and dehiscent facial nerve canal. Methods: Retrospective chart review. Results: A 5-year-old male was referred to the otolaryngology clinic for evaluation of recurrent acute otitis media and hearing loss. He also developed recurrent left peripheral FN palsy associated with episodes of bilateral acute otitis media. High resolution computed tomography of the temporal bones revealed incomplete bony coverage of the tympanic segment of the left facial nerve. Conclusions: Recurrent peripheral FN palsy may occur in children with recurrent acute otitis media in the presence of a dehiscent facial nerve canal. Facial nerve canal dehiscence should be considered in the differential diagnosis of children with recurrent peripheral FN palsy.

2017-12-01

Selective upper airway stimulation (UAS) has shown effectiveness in treating patients with obstructive sleep apnea (OSA). The terminating branches of the hypoglossal nerve show a wide complexity, requiring careful discernment of a functional breakpoint between branches for inclusion and exclusion from the stimulation cuff electrode. The purpose of this study was to describe and categorize the topographic phenotypes of these branches. Thirty patients who received an implant with selective UAS from July 2015 to June 2016 were included. All implantations were recorded using a microscope and resultant tongue motions were captured perioperatively for comparison. Eight different variations of the branches were encountered and described, both in a tabular numeric fashion and in pictorial schema. The examinations showed the complex phenotypic surgical anatomy of the hypoglossal nerve. A schematic classification system has been developed to help surgeons identify the optimal location for cuff placement in UAS. © 2017 Wiley Periodicals, Inc.

Full Text Available Ischemic abducens nerve palsy usually presents as isolated cranial nerve palsy in the middle aged and elderly patients with known risk factors such as diabetes mellitus, hypertension, dyslipidemia, carotid artery disease, etc., In this report, we describe four patients with isolated abducens nerve palsy who presented with an acute onset diplopia whose detailed history and examination were suggestive of an ischemic etiology. Detailed systemic and laboratory evaluation revealed hyperhomocysteinemia as the only potential risk factor. To the best of our knowledge this is the first report of association of hyperhomocysteinemia and isolated abducens nerve palsy.

Our aim was to estimate the value of MRI in detecting irreversibly paralysed facial nerves. We examined 95 consecutive patients with a facial nerve palsy (14 with a persistent palsy, and 81 with good recovery), using a 1.0 T unit, with T2-weighted and contrast-enhanced T1-weighted images. The geniculate ganglion and tympanic segment had gave high signal on T2-weighted images in the chronic stage of persistent palsy, but not in acute palsy. The enhancement pattern of the facial nerve in the chronic persistent facial nerve palsy is similar to that in the acute palsy with good recovery. These findings suggest that T2-weighted MRI can be used to show severely damaged facial nerves. (orig.)

To study the character of facial nerve palsy due to four different auris diseases including chronic otitis media, Hunt syndrome, tumor and physical or chemical factors, and to discuss the principles of the surgical management of otogenic facial nerve palsy. The clinical characters of 24 patients with otogenic facial nerve palsy because of the four different auris diseases were retrospectively analyzed, all the cases were performed surgical management from October 1991 to March 2007. Facial nerve function was evaluated with House-Brackmann (HB) grading system. The 24 patients including 10 males and 14 females were analysis, of whom 12 cases due to cholesteatoma, 3 cases due to chronic otitis media, 3 cases due to Hunt syndrome, 2 cases resulted from acute otitis media, 2 cases due to physical or chemical factors and 2 cases due to tumor. All cases were treated with operations included facial nerve decompression, lesion resection with facial nerve decompression and lesion resection without facial nerve decompression, 1 patient's facial nerve was resected because of the tumor. According to HB grade system, I degree recovery was attained in 4 cases, while II degree in 10 cases, III degree in 6 cases, IV degree in 2 cases, V degree in 2 cases and VI degree in 1 case. Removing the lesions completely was the basic factor to the surgery of otogenic facial palsy, moreover, it was important to have facial nerve decompression soon after lesion removal.

2001-01-01

AIM: The purpose of this study was to investigate the value of contrast-enhanced magnetic resonance (MR) imaging in patients with peripheral facial nerve palsy. MATERIALS AND METHODS: MR imaging was performed in 147 patients with facial nerve palsy, using a 1.0 T unit. All of 147 patients were evaluated by contrast-enhanced MR imaging and the pattern of enhancement was compared with that in 300 control subjects evaluated for suspected acoustic neurinoma. RESULTS: The intrameatal and labyrinthine segments of the normal facial nerve did not show enhancement, whereas enhancement of the distal intrameatal segment and the labyrinthine segment was respectively found in 67% and 43% of patients with Bell's palsy. The geniculate ganglion or the tympanic-mastoid segment was enhanced in 21% of normal controls versus 91% of patients with Bell's palsy. Abnormal enhancement of the non-paralyzed facial nerve was found in a patient with bilateral temporal bone fracture. CONCLUSION: Enhancement of the distal intrameatal and labyrinthine segments is specific for facial nerve palsy. Contrast-enhanced MR imaging can reveal inflammatory facial nerve lesions and traumatic nerve injury, including clinically silent damage in trauma. Kinoshita T. et al. (2001)

Incomplete recovery of facial motor function continues to be long-term sequelae in some patients with Bell's palsy. The purpose of this study was to investigate the efficacy of transmastoid facial nerve decompression after steroid and antiviral treatment in patients with late stage Bell's palsy. Twelve patients underwent surgical decompression for Bell's palsy 21-70 days after onset, whereas 22 patients were followed up after steroid and antiviral therapy without decompression. Surgical criteria included greater than 90 % degeneration on electroneuronography and no voluntary electromyography potentials. This study was a retrospective study of electrodiagnostic data and medical chart review between 2006 and 2013. Recovery from facial palsy was assessed using the House-Brackmann grading system. Final recovery rate did not differ significantly in the two groups; however, all patients in the decompression group recovered to at least House-Brackmann grade III at final follow-up. Although postoperative hearing threshold was increased in both groups, there was no significant between group difference in hearing threshold. Transmastoid decompression of the facial nerve in patients with severe late stage Bell's palsy at risk for a poor facial nerve outcome reduced severe complications of facial palsy with minimal morbidity.

Soft tissue metastases, in particular intraneural metastasis, from any carcinomas seldom occur. To our knowledge, no case of sciatic nerve palsy due to intraneural metastasis of gastric carcinoma is reported in the literature. A case is reported of a 82-year old woman with sciatic nerve palsy with intraneural metastasis of gastric carcinoma. Although she had undergone partial gastrectomy with T2b, N0, M0 two years ago and primary site was cured, she developed sciatic nerve palsy from the carcinoma metastasis directly to the nerve. Operative resection and Histological examination revealed poorly differentiated adenocarcinoma, the same as her primary site adenocarcinoma. Sciatica is usually caused by a herniated disc or spinal canal stenosis. Sciatic nerve palsy may be caused by nondiscogenic etiologies that may be either intrapelvic or extrapelvic. It is important to image the entire course of the nerve to distinguish these etiologies quickly. The longer the nerve compression the less likely a palsy will recover. Surgery is a good intervention that simultaneously obtains a tissue diagnosis and decompresses the nerve

Facial nerve palsy, as a complication of an inferior alveolar nerve block anesthesia, is a rarely reported incident. Based on the time elapsed, from the moment of the injection to the onset of the symptoms, the paralysis could be either immediate or delayed. The purpose of this article is to report a case of delayed facial palsy as a result of inferior alveolar nerve block, which occurred 24 hours after the anesthetic administration and subsided in about 8 weeks. The pathogenesis, treatment, and results of an 8-week follow-up for a 20-year-old patient referred to a private maxillofacial clinic are presented and discussed. The patient's previous medical history was unremarkable. On clinical examination the patient exhibited generalized weakness of the left side of her face with a flat and expressionless appearance, and she was unable to close her left eye. One day before the onset of the symptoms, the patient had visited her dentist for a routine restorative procedure on the lower left first molar and an inferior alveolar block anesthesia was administered. The patient's medical history, clinical appearance, and complete examinations led to the diagnosis of delayed facial nerve palsy. Although neurologic occurrences are rare, dentists should keep in mind that certain dental procedures, such as inferior alveolar block anesthesia, could initiate facial nerve palsy. Attention should be paid during the administration of the anesthetic solution.

Isolated long thoracic nerve palsy results in scapular winging and destabilization. In this study, we review the surgical management of isolated long thoracic nerve palsy and suggest a surgical technique and treatment algorithm to simplify management. In total, 19 patients who required surgery for an isolated long thoracic nerve palsy were reviewed retrospectively. Preoperative demographics, electromyography (EMG), and physical examinations were reviewed. Intraoperative nerve stimulation, surgical decision making, and postoperative outcomes were reviewed. In total, 19 patients with an average age of 32 were included in the study. All patients had an isolated long thoracic nerve palsy caused by either an injury (58%), Parsonage-Turner syndrome (32%), or shoulder surgery (10%); 18 patients (95%) underwent preoperative EMG; 10 with evidence of denervation (56%); and 13 patients had motor unit potentials in the serratus anterior (72%). The preoperative EMG did not correlate with intraoperative nerve stimulation in 13 patients (72%) and did correlate in 5 patients (28%); 3 patients had a nerve transfer (3 thoracodorsal to long thoracic at lateral chest, 1 pec to long thoracic at supraclavicular incision). In the 3 patients who had a nerve transfer, there was return of full forward flexion of the shoulder at an average of 2.5 months. A treatment algorithm based on intraoperative nerve stimulation will help guide surgeons in their clinical decision making in patients with isolated long thoracic nerve palsy. Intraoperative nerve stimulation is the gold standard in the management of isolated long thoracic nerve palsy.

Two different aspects of the influence of neuromonitoring on the possible reduction of post-operative recurrent laryngeal nerve palsies require critical examination: the nerve identification and the monitoring of it's functions. Due to the additional information from the EMG signals, neuromonitoring is the best method for identifying the nerves as compared to visual identification alone. There are still no randomized studies available that compare the visual and electrophysiological recurrent laryngeal nerve detection in thyroid operations with respect to the postoperative nerve palsies. Nevertheless, comparisons with historical collectives show that a constant low nerve-palsy-rate was achieved with electrophysiological detection in comparison to visual detection. The rate of nerve identification is normally very high and amounts to 99 % in our own patients. The data obtained during the "Quality assurance of benign and malignant Goiter" study show that in hemithyreoidectomy and subtotal resection, lower nerve-palsy-rates are achieved with neuromonitoring as compared to solely visual detection. Following subtotal resection, this discrepancy becomes even statistically significant. While monitoring the nerve functions with the presently used neuromonitoring technique, it is possible to observe the EMG-signal remaining constant or decreasing in volume. Assuming that a constant neuromonitoring signal represents a normal vocal cord, our evaluation shows that there is a small percentage of false negative and positive results. Looking at the permanent recurrent nerve palsy rates, this method has a specificity of 98 %, a sensitivity of 100 %, a positive prognostic value of 10 %, and a negative prognostic value of 100 %. Although an altered neuromonitoring signal can be taken as a clear indication of eventual nerve damage, an absolutely reliable statement about the postoperative vocal cord function is presently not possible with intraoperative neuromonitoring.

The case histories of four patients who developed hemiatrophy of the tongue from 3 to 9 years after a course of curative radiation therapy for carcinomas of the head and neck are presented. These patients were subsequently followed from 1 1 / 2 to 6 years without local recurrence of the tumor, distant metastasis, or involvement of other cranial nerves, indicative of only a unilateral hypoglossal nerve atrophy. A review of the literature showed that peripheral and cranial nerve damages after radiation therapy have been reported for the optic nerve, hypoglossal nerve, oculomotor nerve, abducens nerve, recurrent laryngeal nerve, brachial plexus nerves, and peripheral nerves of the extremities. Review of clinical and experimental data indicated that in most cases, the damages were probably caused by extensive connective tissue fibrosis around and infiltrating the nerve trunks. Three possible types of peripheral and cranial nerve damages after radiation therapy are identified. (U.S.)

BACKGROUND: Cranial nerve palsies has several etiologies including vascular insufficiency, neoplasm, trauma and inflammation. Isolated sixth nerve palsy is an extremely rare presenting feature of leukemia. AIM: We describe an unusual ocular presentation of a bilateral progressive sixth nerve palsy in a young male with a preceding head injury. CONCLUSION: Acquired sixth nerve palsies in young adults may be due to trauma but in the absence of a definitive history other systemic processes must be outruled. We describe a case of bilateral sixth nerve palsy in a patient with ALL with no obvious CNS involvement. Potential etiological mechanisms are discussed.

To analyse the patterns of facial nerve canal injury seen at temporal bone computed tomography (CT) in patients with traumatic facial nerve palsy and to correlate these with clinical manifestations and outcome. Thirty cases of temporal bone CT in 29 patients with traumatic facial nerve palsy were analyzed with regard to the patterns of facial nerve canal involvement. The patterns were correlated with clinical grade, the electroneurographic (ENoG) findings, and clinical outcome. For clinical grading, the House-Brackmann scale was used, as follows:grade I-IV, partial palsy group; grade V-VI, complete palsy group. The electroneuronographic findings were categorized as mild to moderate (below 90%) or severe (90% and over) degeneration. In 25 cases, the bony wall of the facial nerve canals was involved directly (direct finding): discontinuity of the bony wall was onted in 22 cases, bony spicules in ten, and bony wall displacement in five. Indirect findings were canal widening in nine cases and adjacent bone fracture in two. In one case, there were no direct or indirect findings. All cases in which there was complete palsy (n=8) showed one or more direct findings including spicules in six, while in the incomplete palsy group (n=22), 17 cases showed direct findings. In the severe degeneration group (n=13), on ENog, 12 cases demonstrated direct findings, including spicules in nine cases. In 24 patients, symptoms of facial palsy showed improvement at follow up evaluation. Four of the five patients in whom symptoms did not improve had spicules. Among ten patients with spicules, five underwent surgery and symptoms improved in four of these; among the five patients not operated on , symptoms did not improve in three. In most patients with facial palsy after temporal bone injury, temporal bone CT revealed direct or indirect facial nerve canal involvement, and in complete palsy or severe degeneration groups, there were direct findings in most cases. We believe that meticulous

Strauss, Lauren; Loder, Elizabeth; Rizzoli, Paul

2014-01-01

Occipital nerve blocks are commonly performed to treat a variety of headache syndromes and are generally believed to be safe and well tolerated. We report the case of an otherwise healthy 24-year-old woman with left side-locked occipital, parietal, and temporal pain who was diagnosed with probable occipital neuralgia. She developed complete left facial nerve palsy within minutes of blockade of the left greater and lesser occipital nerves with a solution of bupivicaine and triamcinolone. Magnetic resonance imaging of the brain with gadolinium contrast showed no abnormalities, and symptoms had completely resolved 4-5 hours later. Unintended spread of the anesthetic solution along tissue planes seems the most likely explanation for this adverse event. An aberrant course of the facial nerve or connections between the facial and occipital nerves also might have played a role, along with the patient's prone position and the use of a relatively large injection volume of a potent anesthetic. Clinicians should be aware that temporary facial nerve palsy is a possible complication of occipital nerve block. © 2014 American Headache Society.

Kim, Na Hyun; Shin, Seung-Ho

2014-03-01

Facial nerve palsy results in the loss of facial expression and is most commonly caused by a benign, self-limiting inflammatory condition known as Bell palsy. However, there are other conditions that may cause facial paralysis, such as neoplastic conditions of the facial nerve, traumatic nerve injury, and temporal bone lesions. We present a case of facial nerve palsy concurrent with a benign cystic lesion of the temporal bone, adjacent to the tympanic segment of the facial nerve. The patient's symptoms subsided after facial nerve decompression via a transmastoid approach.

Objective: To analyze the incidence and causative factors of radiation-induced cranial nerve palsy in patients with nasopharyngeal carcinoma (NPC). Methods: 512 NPC patients who underwent radiotherapy from January 1, 1989 to December 31, 1990 and from January 1, 1994 to December 31, 1995 were retrospectively analyzed. According to Fuzhou' 92 NPC Staging Classification, there are 31 patients in stage I, 212 in stage II, 198 in stage III and 71 in stage IV. All patients were treated by 60 Co or 6 MV X-ray with faciocervical fields or pre-auricular fields to primary area. Some patients were boosted by post-auricular fields or cranial fields. The median dose to the nasopharyngeal region was 7130 cGy by external beam radiotherapy. Thirty-four patients were boosted by brachytherapy. The medial dose to cervical lymph nodes was 6410 cGy as definitive treatment and 5480 cGy as prophylactic treatment. 101 patients were treated with combined chemotherapy. Results: The median follow-up was 6.7 years . Radiation-induced cranial nerve palsies occurred in 81 among the 512 patients. The 5- and 10-year cumulative incidences were 10.3%, 25.4%, respectively. The most common affected nerve was XII. On multivariates analysis, cranial nerve invasion before radiation, chemotherapy, dose to the nasopharyngeal region and age were the independent factors of radiation-induced cranial nerve palsy on nerve I-VII, while the N stage and the radiation fields were independent factors on nerve IX-XII. The cumulative incidence of cranial nerve I-VII palsies increased in patients with cranial nerve invasion, chemotherapy and the dose to the nasopharyngeal region (>7000 cGy). The cumulative incidence of cranial nerve IX- XII palsies increased in patients with advanced N stage. Patients in the first group of treatment field had the highest risk to progress cranial nerve IX-XII palsies, followed by the second group, and the third group had the lowest risk. Only 1 in 34 patients with brachytherapy

Catheter versus non-catheter angiography in isolated third nerve palsy

International Nuclear Information System (INIS)

2007-01-01

To discuss the controversies surrounding the indications for catheter angiography versus non-catheter and less invasive angiography techniques (e.g. magnetic resonance angiography (MRA) and computerized tomography angiography (CTA)) in the evaluation of patients with a third nerve palsy. Clinical opinion-perspective and literature review. The patient with an isolated third nerve palsy might have a vasculopathic (and typically benign, self limited course) etiology or a life threatening intracranial posterior communicating artery aneurysm. Although it is clear that non-isolated third nerve palsies require imaging directed at the topographical localization of the clinical findings, the evaluation of the neurologically isolated third nerve palsy remains controversial. The completeness of the external (i.e. somatic) motor dysfunction and the presence or absence of internal (i.e. pupillary) dysfunction are generally used to guide the choice of initial neuroimaging. Advances in MRA and CTA technology have reduced but not eliminated our dependence upon catheter angiography in this setting. A properly performed and interpreted MRA or CTA probably will be able to detect greater than 95 % of aneurysms producing a third nerve palsy. The issues surrounding the use of catheter angiography in third nerve palsy are reviewed. If the clinician is highly confident in the capability, availability, and reliability of the neuroradiologist and of their institutional experience and quality of less invasive non-catheter MRA and CTA and if the risk of aneurysm is low or if the risk of angiography is high (e.g. elderly, renal failure, iodinated contrast allergy, risk of stroke) then MRI and MRA (or CTA) may be a reasonable alternative to catheter angiography. Patients with a moderate or uncertain risk of aneurysm and a lower risk for catheter angiography or if there is a low confidence in the quality or the interpretation of the institutional MRA (or CTA) may still require catheter

Neuro-ophthalmological approach to facial nerve palsy.

Facial nerve palsy is associated with significant morbidity and can have different etiologies. The most common causes are Bell's palsy, Ramsay-Hunt syndrome and trauma, including surgical trauma. Incidence varies between 17 and 35 cases per 100,000. Initial evaluation should include accurate clinical history, followed by a comprehensive investigation of the head and neck, including ophthalmological, otological, oral and neurological examination, to exclude secondary causes. Routine laboratory testing and diagnostic imaging is not indicated in patients with new-onset Bell's palsy, but should be performed in patients with risk factors, atypical cases or in any case without resolution within 4 months. Many factors are involved in determining the appropriate treatment of these patients: the underlying cause, expected duration of nerve dysfunction, anatomical manifestations, severity of symptoms and objective clinical findings. Systemic steroids should be offered to patients with new-onset Bell's palsy to increase the chance of facial nerve recovery and reduce synkinesis. Ophthalmologists play a pivotal role in the multidisciplinary team involved in the evaluation and rehabilitation of these patients. In the acute phase, the main priority should be to ensure adequate corneal protection. Treatment depends on the degree of nerve lesion and on the risk of the corneal damage based on the amount of lagophthalmos, the quality of Bell's phenomenon, the presence or absence of corneal sensitivity and the degree of lid retraction. The main therapy is intensive lubrication. Other treatments include: taping the eyelid overnight, botulinum toxin injection, tarsorrhaphy, eyelid weight implants, scleral contact lenses and palpebral spring. Once the cornea is protected, longer term planning for eyelid and facial rehabilitation may take place. Spontaneous complete recovery of Bell's palsy occurs in up to 70% of cases. Long-term complications include aberrant regeneration with

Full Text Available Cerebral venous thrombosis (CVT is a rare clinical condition between cerebrovasculer diases. The most common findings are headache, seizure and focal neurological deficit. Multiple cranial nerve palsy due to CVT is rarely seen and it is not clear pathology. A pathology that could explain the lack of cranial nerve imaging is carrying suspected diagnosis but the disease is known to provide early diagnosis and treatment. We want to emphasize with this case multipl cranial nerve palsy due to CVT is seen rarely and good response to treatment.

Park, Yong Ok; Lee, Myeong Jun; Lee, Chang Joon; Yoo, Jeong Hyun

2000-01-01

To evaluate the findings of normal facial nerve, as seen on oblique sagittal MRI using a TMJ (temporomandibular joint) surface coil, and then to evaluate abnormal findings of peripheral facial nerve palsy. We retrospectively reviewed the MR findings of 20 patients with peripheral facial palsy and 50 normal facial nerves of 36 patients without facial palsy. All underwent oblique sagittal MRI using a T MJ surface coil. We analyzed the course, signal intensity, thickness, location, and degree of enhancement of the facial nerve. According to the angle made by the proximal parotid segment on the axis of the mastoid segment, course was classified as anterior angulation (obtuse and acute, or buckling), straight and posterior angulation. Among 50 normal facial nerves, 24 (48%) were straight, and 23 (46%) demonstrated anterior angulation; 34 (68%) showed iso signal intensity on T1W1. In the group of patients, course on the affected side was either straight (40%) or showed anterior angulation (55%), and signal intensity in 80% of cases was isointense. These findings were similar to those in the normal group, but in patients with post-traumatic or post-operative facial palsy, buckling, of course, appeared. In 12 of 18 facial palsy cases (66.6%) in which contrast materials were administered, a normal facial nerve of the opposite facial canal showed mild enhancement on more than one segment, but on the affected side the facial nerve showed diffuse enhancement in all 14 patients with acute facial palsy. Eleven of these (79%) showed fair or marked enhancement on more than one segment, and in 12 (86%), mild enhancement of the proximal parotid segment was noted. Four of six chronic facial palsy cases (66.6%) showed atrophy of the facial nerve. When oblique sagittal MR images are obtained using a TMJ surface coil, enhancement of the proximal parotid segment of the facial nerve and fair or marked enhancement of at least one segment within the facial canal always suggests pathology of

Complete Spinal Accessory Nerve Palsy From Carrying Climbing Gear.

Science.gov (United States)

Coulter, Jess M; Warme, Winston J

2015-09-01

We report an unusual case of spinal accessory nerve palsy sustained while transporting climbing gear. Spinal accessory nerve injury is commonly a result of iatrogenic surgical trauma during lymph node excision. This particular nerve is less frequently injured by blunt trauma. The case reported here results from compression of the spinal accessory nerve for a sustained period-that is, carrying a load over the shoulder using a single nylon rope for 2.5 hours. This highlights the importance of using proper load-carrying equipment to distribute weight over a greater surface area to avoid nerve compression in the posterior triangle of the neck. The signs and symptoms of spinal accessory nerve palsy and its etiology are discussed. This report is particularly relevant to individuals involved in mountaineering and rock climbing but can be extended to anyone carrying a load with a strap over one shoulder and across the body.

Radiation-induced ocular motor cranial nerve palsies in patients with pituitary tumor.

Science.gov (United States)

Vaphiades, Michael S; Spencer, Sharon A; Riley, Kristen; Francis, Courtney; Deitz, Luke; Kline, Lanning B

2011-09-01

Radiation therapy is often used in the treatment of pituitary tumor. Diplopia due to radiation damage to the ocular motor cranial nerves has been infrequently reported as a complication in this clinical setting. Retrospective case series of 6 patients (3 men and 3 women) with pituitary adenoma, all of whom developed diplopia following transsphenoidal resection of pituitary adenoma with subsequent radiation therapy. None had evidence of tumor involvement of the cavernous sinus. Five patients developed sixth nerve palsies, 3 unilateral and 2 bilateral, and in 1 patient, a sixth nerve palsy was preceded by a fourth cranial nerve palsy. One patient developed third nerve palsy. Five of the 6 patients had a growth hormone-secreting pituitary tumor with acromegaly. Following transsphenoidal surgery in all 6 patients (2 had 2 surgeries), 4 had 2 radiation treatments consisting of either radiosurgery (2 patients) or external beam radiation followed by radiosurgery (2 patients). Patients with pituitary tumors treated multiple times with various forms of radiation therapy are at risk to sustain ocular motor cranial nerve injury. The prevalence of acromegalic patients in this study reflects an aggressive attempt to salvage patients with recalcitrant growth hormone elevation and may place the patient at a greater risk for ocular motor cranial nerve damage.

Outcomes of Direct Facial-to-Hypoglossal Neurorrhaphy with Parotid Release.

Lesions of the temporal bone and cerebellopontine angle and their management can result in facial nerve paralysis. When the nerve deficit is not amenable to primary end-to-end repair or interpositional grafting, nerve transposition can be used to accomplish the goals of restoring facial tone, symmetry, and voluntary movement. The most widely used nerve transposition is the hypoglossal-facial nerve anastamosis, of which there are several technical variations. Previously we described a technique of single end-to-side anastamosis using intratemporal facial nerve mobilization and parotid release. This study further characterizes the results of this technique with a larger patient cohort and longer-term follow-up. The design of this study is a retrospective chart review and the setting is an academic tertiary care referral center. Twenty-one patients with facial nerve paralysis from proximal nerve injury at the cerebellopontine angle underwent facial-hypoglossal neurorraphy with parotid release. Outcomes were assessed using the Repaired Facial Nerve Recovery Scale, questionnaires, and patient photographs. Of the 21 patients, 18 were successfully reinnervated to a score of a B or C on the recovery scale, which equates to good oral and ocular sphincter closure with minimal mass movement. The mean duration of paralysis between injury and repair was 12.1 months (range 0 to 36 months) with a mean follow-up of 55 months. There were no cases of hemiglossal atrophy, paralysis, or subjective dysfunction. Direct facial-hypoglossal neurorrhaphy with parotid release achieved a functional reinnervation and good clinical outcome in the majority of patients, with minimal lingual morbidity. This technique is a viable option for facial reanimation and should be strongly considered as a surgical option for the paralyzed face.

The study describes the epidemiology, treatment, and treatment outcomes of the 10 cases of facial nerve palsy seen in children managed at the Obafemi Awolowo University Teaching Hospitals Complex, Ile-Ife over a 10 year period. It also compares findings with report from developed countries. This was a retrospective cohort review of pediatric cases of facial nerve palsy encountered in all the clinics run by specialists in the above named hospital. A diagnosis of facial palsy was based on International Classification of Diseases, Ninth Revision, Clinical Modification codes. Information retrieved from the case note included sex, age, number of days with lesion prior to presentation in the clinic, diagnosis, treatment, treatment outcome, and referral clinic. Only 10 cases of facial nerve palsy were diagnosed in the institution during the study period. Prevalence of facial nerve palsy in this hospital was 0.01%. The lesion more commonly affected males and the right side of the face. All cases were associated with infections: Mainly mumps (70% of cases). Case management include the use of steroids and eye pads for cases that presented within 7 days; and steroids, eye pad, and physical therapy for cases that presented later. All cases of facial nerve palsy associated with mumps and malaria infection fully recovered. The two cases of facial nerve palsy associated with otitis media only partially recovered. Facial nerve palsy in pediatric patients is more commonly associated with mumps in the study environment. Successes are recorded with steroid therapy.

Quantitative analysis of the facial nerve on the lesion side as well as the normal side, which allowed for more accurate measurement of facial nerve enhancement in patients with facial palsy, showed statistically significant correlation with the initial severity of facial nerve inflammation, although little prognostic significance was shown. This study investigated the clinical significance of quantitative measurement of facial nerve enhancement in patients with Bell's palsy by analyzing the enhancement pattern and correlating MRI findings with initial severity of facial palsy and clinical outcome. Facial nerve enhancement was measured quantitatively by using the region of interest on pre- and postcontrast T1-weighted images in 44 patients diagnosed with Bell's palsy. The signal intensity increase on the lesion side was first compared with that of the contralateral side and then correlated with the initial degree of facial palsy and prognosis. The lesion side showed significantly higher signal intensity increase compared with the normal side in all of the segments except for the mastoid segment. Signal intensity increase at the internal auditory canal and labyrinthine segments showed correlation with the initial degree of facial palsy but no significant difference was found between different prognostic groups.

Unilateral phrenic nerve palsy as initial presentation of the retrosternal goitre is extremely rare event. This is a case report of a 57-year-old woman with history of cough and breathlessness of 3 months duration, unaware of the thyroid mass. She had large cervico-mediastinal goiter and chest radiograph revealed raised left sided hemidiaphragm. Chest CT scan did not reveal any lung parenchymal or mediastinal pathology. The patient underwent a total thyroidectomy through a cervical approach. The final pathology was in favor of multinodular goitre. Even after 1 year of follow up, phrenic nerve palsy did not improve indicating permanent damage. Phrenic nerve palsy as initial presentation of the retrosternal goitre is unusual event. This case is reported not only because of the rare nature of presentation, but also to make clinicians aware of the entity so that early intervention may prevent attendant morbidity.

Primary oculomotor nerve palsy due to mild head injury. Report of two cases

International Nuclear Information System (INIS)

Katsuno, Makoto; Kobayashi, Shiro; Yokota, Hiroyuki; Teramoto, Akira

2008-01-01

Two patients with primary oculomotor nerve palsy due to direct mild head injury are reported. They presented with internal ophthalmoplegia, dilated nonreactive pupils, and very mild disturbance in consciousness. Except for the persistent oculomotor nerve palsy, both the patients recovered fully within one week. Neither demonstrated a history that was suggestive of a cause for their oculomotor nerve palsy. Initial CT scans demonstrated localized subarachnoid hemorrhage around the brain stem. One of the patients had sustained a fracture of the anterior clinoid process. As the underlying pathophysiologic mechanism underlying the oculomotor nerve palsy we suspected mild injury to the pupillomotor fibers at the anterior petroclinoidal ligament and that of the pupillary fibers at the posterior petroclinoidal ligament. We speculate that these perforating fibers at the anterior petroclinoidal ligament acted as a fulcrum due to downward displacement of the brainstem at the time of impact. (author)

Isolated unilateral sixth cranial nerve palsy: A rare presentation of dengue fever

Directory of Open Access Journals (Sweden)

Yang Liang Boo

2016-11-01

Full Text Available Dengue fever is a common mosquito-borne viral infection endemic in tropical and subtropical countries. Neurological manifestations in dengue infection are relatively uncommon, and include encephalitis, encephalopathy, neuromuscular disorders and neuro-ocular disorders. Cranial mononeuropathy is a rare manifestation of dengue infection. A 40-year-old man was diagnosed with isolated, unilateral sixth cranial nerve palsy complicating dengue infection. The patient was managed accordingly, and full ocular recovery was observed. This was the first reported case of isolated sixth cranial nerve palsy associated with dengue fever in Malaysia. It is important for clinicians to consider dengue as a differential diagnosis in patients presenting with fever and sixth cranial nerve palsy.

2007-08-01

Full Text Available Abstract Background Solitary involvement of the sphenoid sinus has rarely been reported in non-Hodgkin's lymphoma. Isolated oculomotor nerve palsy is uncommon as an initial presentation of malignant tumors of the sphenoid sinus. Case presentation A 53-year-old woman presented with a three-month history of headache and diplopia. Neurological examination revealed complete left oculomotor nerve palsy. Magnetic Resonance Imaging (MRI demonstrated a homogenous soft-tissue lesion occupying the left sphenoid sinus and invading the left cavernous sinus. The patient underwent transsphenoidal biopsy and the lesion was histologically diagnosed as non-Hodgkin's lymphoma, diffuse large B-cell type. Tumor cells were positive for CD20 and negative for CD3. Following six cycles of chemotherapy, the left oculomotor nerve palsy that had been previously observed was completely resolved. There was no enhancing lesion noted on follow-up MRI. Conclusion It is important to recognize that non-Hodgkin's lymphoma of the sphenoid sinus can present with isolated oculomotor nerve palsy, although it is extremely rare. The cranial nerve deficits can resolve dramatically after chemotherapy.

Multiple cranial nerves palsies following a posterior fossa exploration confined to an extradural compartment is a rare clinical presentation. This case report describes a young man who developed a unilateral abducens and bilateral facial nerve palsies following a posterior fossa exploration confined to an extradural compartment. There are different theories to explain this presentation, but the exact mechanism remains unclear. We propose that this patient cranial nerve palsies developed following cerebrospinal fluid (CSF) leak, potentially as a consequence of rapid change in CSF dynamics.

Bell palsy in lyme disease-endemic regions of canada: a cautionary case of occult bilateral peripheral facial nerve palsy due to Lyme disease.

Science.gov (United States)

Ho, Karen; Melanson, Michel; Desai, Jamsheed A

2012-09-01

Lyme disease caused by the spirochete Borrelia burgdorferi is a multisystem disorder characterized by three clinical stages: dermatologic, neurologic, and rheumatologic. The number of known Lyme disease-endemic areas in Canada is increasing as the range of the vector Ixodes scapularis expands into the eastern and central provinces. Southern Ontario, Nova Scotia, southern Manitoba, New Brunswick, and southern Quebec are now considered Lyme disease-endemic regions in Canada. The use of field surveillance to map risk and endemic regions suggests that these geographic areas are growing, in part due to the effects of climate warming. Peripheral facial nerve palsy is the most common neurologic abnormality in the second stage of Lyme borreliosis, with up to 25% of Bell palsy (idiopathic peripheral facial nerve palsy) occurring due to Lyme disease. Here we present a case of occult bilateral facial nerve palsy due to Lyme disease initially diagnosed as Bell palsy. In Lyme disease-endemic regions of Canada, patients presenting with unilateral or bilateral peripheral facial nerve palsy should be evaluated for Lyme disease with serologic testing to avoid misdiagnosis. Serologic testing should not delay initiation of appropriate treatment for presumed Bell palsy.

Electron microscopic localization of 3H-leucine in the neurons of the hypoglossal nerve during axonal reaction

International Nuclear Information System (INIS)

Gylybov, G.P.; Chuchkov, Ch.Kh.; Davidov, M.S.

1978-01-01

The uptake of tritium-labelled leucine in the neuronal organelles with the aim of a follow-up of the dynamics in the protein synthesis in the motoneurons affected during axonal reaction was investigated. The experiments were carried out with rats, of which one of the hypoglossal nerve was crushed and the other was left intact. The labelled amino-acid was injected in the lateral cerebral ventricle 30 to 40 min before the sacrificing of each animal. The examination of the histological preparations shows that the neurons of the hypoglossal nerve cumulate to a larger extent the labelled precursor in comparison with the neuroglia. The perinuclear region, the nucleus, the nucleolus and the axonal hillock show preponderance in the accumulation. The activity greatly decreases at the more remote parts of the axon. The electron=microscopic data confirm these results and supplement them by exactly determining the localization of the labels in the individual organelles. The highest activity was found in the mitochondria, in the Golgi apparatus and in the lysosomes. This can be viewed as the result of intensified transfer of proteins from the ribosomes toward these organelles. There is, however, another possibility - the directly elevated biosynthesis. The elevated activity of the protein synthesis in the cell organelles, assume the authors, is related not only to preserving their structural proteins but also to intensifying axonal transport.

Grabau, Olga; Leonhardi, Jochen; Reimers, Carl D.

2014-01-01

Introduction: Recurrent oculomotor nerve palsies are extremely rare clinical conditions. Case report: Here, we report on a unique case of a short-lasting recurrent unilateral incomplete external and complete internal oculomotor nerve palsy. The episodic palsies were probably caused by an ipsilateral mesencephalic metastasis of a breast carcinoma and occurred after successful brain radiation therapy. Discussion: While the pathogenic mechanism remains unclear, the recurrent sudden onset and disappearance of the palsies and their decreasing frequency after antiepileptic treatment suggest the occurrence of epilepsy-like brainstem seizures. A review of case reports of spontaneous reversible oculomotor nerve palsies is presented. PMID:25104947

Unilateral facial weakness is common. Transcranial magnetic stimulation (TMS) allows identification of a conduction failure at the level of the canalicular portion of the facial nerve and may help to confirm the diagnosis. We retrospectively analyzed 216 patients with the diagnosis of peripheral facial palsy. The electrophysiological investigations included the blink reflex, preauricular electrical stimulation and the response to TMS at the labyrinthine part of the canalicular proportion of the facial nerve within 3 days after symptom onset. A similar reduction or loss of the TMS amplitude (p facial palsy without being specific for Bell's palsy.

Microcystic adnexal carcinoma (MAC)-like squamous cell carcinoma as a differential diagnosis to Bell´s palsy: review of guidelines for refractory facial nerve palsy.

Mueller, S K; Iro, H; Lell, M; Seifert, F; Bohr, C; Scherl, C; Agaimy, A; Traxdorf, M

2017-01-05

Bell´s palsy is the most common cause of facial paralysis worldwide and the most common disorder of the cranial nerves. It is a diagnosis of exclusion, accounting for 60-75% of all acquired peripheral facial nerve palsies. Our case shows the first case of a microcystic adnexal carcinoma-like squamous cell carcinoma as a cause of facial nerve palsy. The patient, a 70-year-old Caucasian male, experienced subsequent functional impairment of the trigeminal and the glossopharyngeal nerve about 1½ years after refractory facial nerve palsy. An extensive clinical work-up and tissue biopsy of the surrounding parotid gland tissue was not able to determine the cause of the paralysis. Primary infiltration of the facial nerve with subsequent spreading to the trigeminal and glossopharyngeal nerve via neuroanastomoses was suspected. After discussing options with the patient, the main stem of the facial nerve was resected to ascertain the diagnosis of MAC-like squamous cell carcinoma, and radiochemotherapy was subsequently started. This case report shows that even rare neoplastic etiologies should be considered as a cause of refractory facial nerve palsy and that it is necessary to perform an extended diagnostic work-up to ascertain the diagnosis. This includes high-resolution MRI imaging and, as perilesional parotid biopsies might be inadequate for rare cases like ours, consideration of a direct nerve biopsy to establish the right diagnosis.

Motor palsies of cranial nerves (excluding VII) after vaccination: reports to the US Vaccine Adverse Event Reporting System.

Science.gov (United States)

Woo, Emily Jane; Winiecki, Scott K; Ou, Alan C

2014-01-01

We reviewed cranial nerve palsies, other than VII, that have been reported to the US Vaccine Adverse Event Reporting System (VAERS). We examined patterns for differences in vaccine types, seriousness, age, and clinical characteristics. We identified 68 reports of cranial nerve palsies, most commonly involving the oculomotor (III), trochlear (IV), and abducens (VI) nerves. Isolated cranial nerve palsies, as well as palsies occurring as part of a broader clinical entity, were reported. Forty reports (59%) were classified as serious, suggesting that a cranial nerve palsy may sometimes be the harbinger of a broader and more ominous clinical entity, such as a stroke or encephalomyelitis. There was no conspicuous clustering of live vs. inactivated vaccines. The patient age range spanned the spectrum from infants to the elderly. Independent data may help to clarify whether, when, and to what extent the rates of cranial nerve palsies following particular vaccines may exceed background levels.

Knowledge of the possible neural interconnections found between the lower cranial and upper cervical nerves may prove useful to surgeons who operate on the skull base and upper neck regions in order to avoid inadvertent traction or transection. We review the literature regarding the anatomy, function, and clinical implications of the complex neural networks formed by interconnections between the lower cranial and upper cervical nerves. A review of germane anatomic and clinical literature was performed. The review is organized into two parts. Part I discusses the anastomoses between the trigeminal, facial, and vestibulocochlear nerves or their branches and other nerve trunks or branches in the vicinity. Part II deals with the anastomoses between the glossopharyngeal, vagus, accessory and hypoglossal nerves and their branches or between these nerves and the first four cervical spinal nerves; the contribution of the autonomic nervous system to these neural plexuses is also briefly reviewed. Part II is presented in this article. Extensive and variable neural anastomoses exist between the lower cranial nerves and between the upper cervical nerves in such a way that these nerves with their extra-axial communications can be collectively considered a plexus.

Full Text Available Victoria Cui,1 Timur Kouliev2 1Washington University School of Medicine, St Louis, MO, USA; 2Emergency Department, Beijing United Family Hospital, Beijing, China Abstract: Acute subdural hematoma (SDH resulting from head trauma is a potentially life-threatening condition that requires expedient diagnosis and intervention to ensure optimal patient outcomes. Rapidly expanding or large hematomas, elevated intracranial pressure, and associated complications of brain herniation are associated with high mortality rates and poor recovery of neurological function. However, smaller bleeds (clot thickness <10 mm or hematomas occurring in infrequent locations, such as the tentorium cerebelli, may be difficult to recognize and patients may present with unusual or subtle signs and symptoms, including isolated cranial nerve palsies. Knowledge of neuroanatomy supported by modern neuroimaging can greatly aid in recognition and diagnosis of such lesions. In this report, we present a case of isolated oculomotor nerve palsy resulting from compressive tentorial SDH following blunt head trauma, review the literature concerning similar cases, and make recommendations regarding the diagnosis of SDH in patients presenting with isolated cranial nerve palsies. Keywords: head injury, oculomotor, palsy, subdural hematoma, trauma, tentorium, cerebral herniation, intracranial hemorrhage

Phrenic nerve palsy is a peripheral nerve disorder caused by excessive cervical extension due to birth trauma or cardiac surgery. We describe two new patients with phrenic nerve palsy associated with birth trauma. Both patients exhibited profound dyspnea and general hypotonia immediately after birth. A chest roentgenogram and fluoroscopy revealed elevation of the diaphragm, leading to a diagnosis of phrenic nerve palsy associated with birth trauma. Since they had intermittently exhibited dyspnea and recurrent infection, we performed video-assisted thoracoscopic surgery (VATS) plication in both cases, at an early and a late stage, respectively. Both patients subsequently exhibited a dramatic improvement in dyspnea and recurrent respiratory infection. Interestingly, the late stage operated infant exhibited spontaneous recovery at 7 months with cessation of mechanical ventilation once. However, this recovery was transient and subsequently led to an increased ventilation volume demand, finally resulting in surgical treatment at 15 months. Histological examination of the diaphragm at this time showed grouped muscle atrophy caused by phrenic nerve degeneration. To our knowledge, this is the first pathologically proven report of grouped muscle atrophy of the diaphragm due to phrenic nerve degeneration, suggesting that partial impairment of phrenic nerves resulted in respiratory dysfunction with incomplete recovery. We conclude that recently developed VATS plication is a safe and effective treatment for infants with phrenic nerve palsy, and should be considered as a surgical treatment at an early period.

El-Boghdadly, Kariem; Chin, Ki Jinn; Chan, Vincent W S

2017-07-01

Regional anesthesia has an established role in providing perioperative analgesia for shoulder surgery. However, phrenic nerve palsy is a significant complication that potentially limits the use of regional anesthesia, particularly in high-risk patients. The authors describe the anatomical, physiologic, and clinical principles relevant to phrenic nerve palsy in this context. They also present a comprehensive review of the strategies for reducing phrenic nerve palsy and its clinical impact while ensuring adequate analgesia for shoulder surgery. The most important of these include limiting local anesthetic dose and injection volume and performing the injection further away from the C5-C6 nerve roots. Targeting peripheral nerves supplying the shoulder, such as the suprascapular and axillary nerves, may be an effective alternative to brachial plexus blockade in selected patients. The optimal regional anesthetic approach in shoulder surgery should be tailored to individual patients based on comorbidities, type of surgery, and the principles described in this article.

Although herpes simplex virus type 1 (HSV-1) is a causative agent of Bell palsy, the precise mechanism of the paralysis remains unknown. It is necessary to investigate the pathogenesis and treatment of Bell palsy due to HSV-1 infection. This study elucidated the role of nitric oxide (NO) in the incidence of facial nerve paralysis caused by HSV-1 in mice and to evaluate the possible role of edaravone, a free radical scavenger, in preventing the paralysis. Sixty-two mice served as animal models of Bell palsy in this laboratory study conducted at an academic institution. Levels of NO in the facial nerve were measured using high-performance liquid chromatography and absorption photometry. The incidence of facial palsy was assessed following administration of edaravone immediately after HSV-1 inoculation and daily for 11 days thereafter. The ratio of NO (inoculated side to control side) and incidence of facial palsy. RESULTS Before the onset of facial palsy, no substantial difference in the NO level was noted between the HSV-1-inoculated side and the control side. When facial palsy occurred, usually at 7 days after inoculation, the NO level was significantly higher on the inoculated side than on the control side. Following recovery from the palsy, the high NO level of the inoculated side decreased. No increase in the NO level was observed in animals without transient facial palsy. When edaravone was administered, the incidence of facial palsy decreased significantly. These findings suggest that NO produced by inducible NO synthase in the facial nerve plays an important role in the onset of facial palsy caused by HSV-1 infection, which is considered a causative virus of Bell palsy. Hato and colleagues elucidate the role of nitric oxide in HSV-1–related facial nerve paralysis in mice and evaluate the role of edaravone, a free radical scavenger, in preventing the paralysis.

We performed enhanced MRI using Gd-DTPA in 84 patients with facial palsy. After assessing enhancement of the normal facial nerve, we examined enhancement in patients with Bell's palsy and Ramsay Hunt syndrome. In 95% of patients with Bell's palsy, enhancement was obtained in the distal IAC and labyrinthine portions. In 72%, enhancement was significant from the distal IAC portion through the vertical portion. In some of the patients who underwent enhanced MRI twice, increased signal intensity was observed in distal portions such as the vertical portion. In many cases of Ramsay Hunt syndrome, enhancement was seen extensively in the IAC portion through the vertical portion. In the subjects with internal auditory symptoms such as vertigo and tinnitus, enhancement of the IAC portion was seen not only in the facial nerve but also in the vestibular and the cochlear nerves. These results suggest that the vascular permeability of lesions in Bell's palsy may be increased from the distal IAC portion to the vertical portion. Judging from the present findings with Ramsay Hunt syndrome, symptoms related to the enhanced portions suggest that accompanying internal auditory symptoms occur due to inflammation of the IAC portions of cochlear and vestibular nerves.

2013-08-01

Conclusion: Based on this meta-analysis, statistically significant differences were determined in terms of the incidences of total and transient recurrent laryngeal nerve palsy after using IONM versus recurrent laryngeal nerve identification alone during thyroidectomy. However, no statistically significant differences were identified regarding the incidence of persistent recurrent laryngeal nerve palsy between groups.

Full Text Available A 30-year-old primigravida presented with isolated left sixth nerve palsy at 38 weeks gestation. Her MRI showed a lesion consistent with central pontine myelinolysis (CPM. Extensive investigations did not reveal any secondary cause for the CPM. She recovered spontaneously in 2 weeks with complete resolution of her MRI changes. To our knowledge, this is the first report of CPM occurring in third trimester in the absence of identifiable secondary causes and of CPM presenting as an isolated sixth nerve palsy. We discuss the reported causes of CPM in pregnancy, possible pathophysiologic mechanisms involved and the anatomic basis of the unique clinical presentation of sixth nerve palsy in our case.

Ulnar and median nerve transfers to arm muscles have been used to recover elbow flexion in infants with neonatal brachial plexus palsy, but there is no direct outcome comparison with the classical supraclavicular nerve grafting approach. We retrospectively analyzed patients with C5-C7 neonatal brachial plexus palsy submitted to nerve surgery and recorded elbow flexion recovery using the active movement scale (0-7) at 12 and 24 months after surgery. We compared 13 patients submitted to supraclavicular nerve grafting with 21 patients submitted to distal ulnar or median nerve transfer to biceps motor branch. We considered elbow flexion scores of 6 or 7 as good results. The mean elbow flexion score and the proportion of good results were better using distal nerve transfers than supraclavicular grafting at 12 months (p nerve grafting at 12 months showed good elbow flexion recovery after ulnar nerve transfers. Distal nerve transfers provided faster elbow flexion recovery than supraclavicular nerve grafting, but there was no significant difference in the outcome after 24 months of surgery. Patients with failed supraclavicular grafting operated early can still benefit from late distal nerve transfers. Supraclavicular nerve grafting should remain as the first line surgical treatment for children with neonatal brachial plexus palsy.

Full Text Available BACKGROUND A comprehensive analysis of the aetiology and clinical profile of isolated infranuclear abducens nerve palsy in a tertiary eye care centre. MATERIALS AND METHODS A hospital-based retrospective case series analysis of 90 isolated infranuclear neurogenic abducens nerve palsies. Documentation included age, gender, presenting complaints, history of diabetes mellitus, hypertension, mode of onset, progression of the disease, treatment given and recovery rate was evaluated. Detailed ophthalmic evaluation of both eyes including anterior segment examination, extraocular movements, diplopia charting and Hess charting. Thorough central nervous system examination and systemic examination was done. Inclusion Criteria- All isolated infranuclear neurogenic lesions of abducens nerve palsy. Exclusion Criteria- Conditions like supranuclear lesions, myasthenia, orbital inflammation and myopathies, false localising sign of abducens nerve palsy were excluded by appropriate testing and investigations. RESULTS Total cases were 90 patients. Mean age of presentation was between 3rd to 5th decades with male preponderance. Commonest presenting symptom was diplopia (71.1%, commonest cause being idiopathic neuritis (48%, diabetes mellitus (20%, hypertension (15%, trauma (10% and others (7%. CONCLUSION In our study, isolated infranuclear abducens nerve palsy with nonspecific aetiology predominantly affecting males of 3 rd to 5 th decade with variable recovery rates were seen. Hence, careful clinical examination in all cases is essential with close follow up on a long-time basis.

Myelography and CT myelography (CMT) were reviewed in 18 cases of birth palsy with clinically suspected avulsion injury. Root-somatosensory evoked potential (root-SEP) was also reviewed for myelographic evaluation of the nerve root avolusion in birth palsy. Root-SEP is not induced in case of avulsed nerve roots, but is induced in case of both normal and incompletely avulsed roots. Myelography demonstrated 58 abnormal nerve roots in 18 cases (19 limbs); 45 (78%) complete and 13 (22%) incomplete nerve root avulsions. Each of complete and incomplete avulsions was defined as total absence and partial presence of rootlets on myelography, respectively. Traumatic meningoceles were detected at 46 roots (79%) on myelography and/or CTM; 35 roots on myelography and 45 roots on CTM. CTM could not detect only a very small meningocele at one root. At 11 roots CTM was superior to myelography in delineating a meningocele because CTM is sensitive to a poorly enhanced meningocele. CTM, however, could not diagnose nerve root avulsions so accurately as myelography, since myelography detected 12 (7 completely and 5 incompletely) avulsed roots without meningocele, whereas CTM could not delineate the nerve roots clearly. Thus, myelography is indispensable to evaluate nerve root avulsions without meningocele. Root-SEP was examined in 9 patients who underwent branchial plexus exploration. SEP was negative at 22/25 roots with complete avulsion and was positive at 7/7 roots with myelographically incomplete avulsion, regardless of presence or absence of any traumatic meningocele. Myelography and root-SEP correlated well at 29 (92%) out of 32 roots in evaluating complete and incomplete avulsion injuries. Myelography and root-SEP were not considered in 3 roots. Though myelography demonstrated complete avulsions with traumatic meningocele, SEP was positive in these three roots, which were interpreted as partially avulsed roots. (J.P.N.).

2016-01-01

Facial nerve injury following head trauma is a frequent event with or without temporal bone fractures. Computed tomography is the imaging modality of choice for assessing the possible bone disruption of the facial nerve canal. Magnetic resonance is helpful in presence of a facial nerve paralysis, unexplained by computed tomography findings. We present a case of delayed post-traumatic facial nerve palsy without radiological evidence of temporal bone fractures, in which magnetic resonance was crucial for diagnosing the nerve impairment. Radiological findings in accordance both with electrodiagnostic tests and clinical presentation suggested the successful conservative management. - Highlights: • Facial nerve is more prone to damage than any other cranial nerve after trauma. • Facial nerve trauma is usually associated with temporal bone fractures. • MRI is mandatory in case of no evidence of bone disruption at CT.

Bilateral facial nerve palsy is a rare and sometimes difficult diagnosis. We describe a case of bilateral simultaneous facial nerve palsy associated with Epstein-Barr virus (EBV) infection in a 3-year-old boy. Several symptoms led to the diagnosis of EBV infection: the clinical situation (fever, stomachache, and throat infection), white blood cell count (5300/mm 3 with 70% lymphocyte count), seroconversion with EBV-specific antibodies, lymphocytic meningitis, and a positive blood EBV polymerase chain reaction (9.3×10 3 copies of EBV-DNA). An MRI brain scan showed bilateral gadolinium enhancement of the facial nerve. A treatment plan with IV antibiotics (ceftriaxone) and corticosteroids was implemented. Antibiotics were stopped after the diagnosis of Lyme disease was ruled out. The patient's facial weakness improved within a few weeks. Bilateral facial nerve palsy is rare and, unlike unilateral facial palsy, it is idiopathic in only 20% of cases. Therefore, it requires further investigation and examination to search for the underlying etiology. Lyme disease is the first infectious disease that should be considered in children, especially in endemic areas. An antibiotic treatment effective against Borrelia burgdorferi should be set up until the diagnosis is negated or confirmed. Further examination should include a blood test (such as immunologic testing, and serologic testing for viruses and bacterium with neurological tropism), a cerebrospinal fluid test, and an MRI brain scan to exclude any serious or curable underlying etiology. Facial bilateral nerve palsy associated with EBV is rarely described in children. Neurological complications have been reported in 7% of all EBV infections. The facial nerve is the most frequently affected of all cranial nerves. Facial palsy described in EBV infections is bilateral in 35% of all cases. The physiopathology is currently unknown. Prognosis is good most of the time. Copyright © 2017 Elsevier Masson SAS. All rights reserved.

Full Text Available Objective: Synkiesia is a sequel of facial nerve palsy. It usually begins 3-4 months after axonal regeneration and progressed up to two years afterward. Treatment of synkinesia is very difficult and sometimes impossible.The aim of our study is find a better procedure to treat facial nerve palsy and prevent synkinesia. Materials and Methods: Twenty nine patients with facial nerve palsy were selected by electrodiagnosis tests. They were divided in two groups. The experimental group was treated by biofeedback electromyography and the second group was treated by common physiotherapy. The evaluation of all patients was done by Photoshop assessment and facial grading scale before and after treatment. Result: After the treatment, a significant general improvement was observed in both groups (p<0.05, but in experimental group (biofeedback showed better result than the other one. The number of patients with synkinesia as well as the severity of their synkinesis in experimental group were lesser than the other one. Conclusion: Biofeedback therapy is more efficient than common physiotherapy.By using this approach, control and reducing synkinesia is more feasible. Assessment by Pohotoshop procedure showed better accuracy than facial grading scale.

The purpose of this study was to identify the cisternal segment of the abducens nerve and to investigate its anatomical features using three-dimensional Fourier transform constructive interference in steady-state (3-D CISS) sequence with a 1.5-tesla magnetic resonance (MR) imaging system. Images of abducens nerve palsy were also studied. Using this imaging system, the following procedures were performed to identify the abducens nerve. First, gray scale of the original images was inverted (inverted image). Second, Dollero's canal was identified, which contains the abducens nerve, and third, the nerve was followed to the root exit zone with a multiple-planar reconstruction method. Twenty-one volunteers and 3 patients with abducens nerve palsies participated in this study and following results were derived: all nerves in volunteers were clearly identified in the coronal and sagittal planes, the images closely resembled autopsy cases, seven nerves in asymptomatic cases were remarkably distorted by the vessels, and the cause of the palsy was not clear by their shapes in the images; this technique, however, can play a great role in evaluating abducens nerve palsy.

Immediate Nerve Transfer for Treatment of Peroneal Nerve Palsy Secondary to an Intraneural Ganglion: Case Report and Review.

Science.gov (United States)

Ratanshi, Imran; Clark, Tod A; Giuffre, Jennifer L

2018-05-01

Intraneural ganglion cysts, which occur within the common peroneal nerve, are a rare cause of foot drop. The current standard of treatment for intraneural ganglion cysts involving the common peroneal nerve involves (1) cyst decompression and (2) ligation of the articular nerve branch to prevent recurrence. Nerve transfers are a time-dependent strategy for recovering ankle dorsiflexion in cases of high peroneal nerve palsy; however, this modality has not been performed for intraneural ganglion cysts involving the common peroneal nerve. We present a case of common peroneal nerve palsy secondary to an intraneural ganglion cyst occurring in a 74-year-old female. The patient presented with a 5-month history of pain in the right common peroneal nerve distribution and foot drop. The patient underwent simultaneous cyst decompression, articular nerve branch ligation, and nerve transfer of the motor branch to flexor hallucis longus to a motor branch of anterior tibialis muscle. At final follow-up, the patient demonstrated complete (M4+) return of ankle dorsiflexion, no pain, no evidence of recurrence and was able to bear weight without the need for orthotic support. Given the minimal donor site morbidity and recovery of ankle dorsiflexion, this report underscores the importance of considering early nerve transfers in cases of high peroneal neuropathy due to an intraneural ganglion cyst.

Posterior interosseous nerve palsy as a complication of friction massage in tennis elbow.

Wu, Ya-Ying; Hsu, Wei-Chih; Wang, Han-Cheng

2010-08-01

Friction massage is a commonly used physical therapy that is usually safe and without complication. We report an unusual case of posterior interosseous nerve palsy that arose after friction massage. Electrophysiologic findings confirmed a focal neuropathy 4-6 cm distal to the lateral epicondyle. The neurologic symptoms resolved completely 2 mos after discontinuation of friction massage. This case experience broadens the spectrum of etiologies of posterior interosseous nerve palsy. Nerve conduction studies may be a useful adjunct to a thorough physical examination to confirm the diagnosis and is important to prognostic evaluation, if unexplained neurologic symptoms develop after certain physical therapy procedures. Further treatment includes avoiding compression and observation.

[Treatment of idiopathic peripheral facial nerve paralysis (Bell's palsy)].

Science.gov (United States)

Meyer, Martin Willy; Hahn, Christoffer Holst

2013-01-28

Bell's palsy is defined as an idiopathic peripheral facial nerve paralysis of sudden onset. It affects 11-40 persons per 100,000 per annum. Many patients recover without intervention; however, up to 30% have poor recovery of facial muscle control and experience facial disfigurement. The aim of this study was to make an overview of which pharmacological treatments have been used to improve outcomes. The available evidence from randomized controlled trials shows significant benefit from treating Bell's palsy with corticosteroids but shows no benefit from antivirals.

Although glufosinate ammonium herbicides are considered safe when used properly, ingestion of the undiluted form can cause grave outcomes. Recently, we treated a 34-yr-old man who ingested glufosinate ammonium herbicide. In the course of treatment, the patient developed apnea, mental deterioration, and sixth cranial nerve palsy; he has since been discharged with full recovery after intensive care. This case report describes the clinical features of glufosinate intoxication with a focus on sixth cranial nerve palsy. Our observation suggests that neurologic manifestations after ingestion of a "low-grade toxicity herbicide" are variable and more complex than that was previously considered.

Isolated Bilateral Fourth Cranial Nerve Palsies as the Presenting Sign of Hydrocephalus

Directory of Open Access Journals (Sweden)

Dimosthenis Mantopoulos

2011-07-01

Full Text Available Midbrain lesions leading to bilateral fourth nerve palsies are typically accompanied by other brainstem symptomatology. Here we report a case of a 29-year-old man with hydrocephalus and significant third ventricle dilation applying pressure on the dorsal midbrain and having as the only manifestation isolated, bilateral fourth cranial nerve palsies. This finding, reported here for the first time, could be attributed to a partially working ventriculoperitoneal shunt previously placed in this patient, which was able to sporadically relieve the increases of the intraventricular pressure on the midbrain that would normally lead to other manifestations.

2013-05-01

Persistent phrenic nerve palsy is the most frequent complication of cryoballoon ablation for atrial fibrillation and can be disabling. To describe a technique-immediate balloon deflation (IBD)-for the prevention of persistent phrenic nerve palsy, provide data for its use, and describe in vitro simulations performed to investigate the effect of IBD on the atrium and pulmonary vein. Cryoballoon procedures for atrial fibrillation were analyzed retrospectively (n = 130). IBD was performed in patients developing phrenic nerve dysfunction (n = 22). In vitro simulations were performed by using phantoms. No adverse events occurred, and all patients recovered normal phrenic nerve function before leaving the procedure room. No patient developed persistent phrenic nerve palsy. The mean cryoablation time to onset of phrenic nerve dysfunction was 144 ± 64 seconds. Transient phrenic nerve dysfunction was seen more frequently with the 23-mm balloon than with the 28-mm balloon (11 of 39 cases vs 11 of 81 cases; P = .036). Balloon rewarming was faster following IBD. The time to return to 0 and 20° C was shorter in the IBD group (6.7 vs 8.9 seconds; P = .007 and 16.7 vs 37.6 seconds; Pphrenic nerve palsy. Simulations suggest that IBD is unlikely to damage the atrium or pulmonary vein. Copyright © 2013 Heart Rhythm Society. All rights reserved.

Full Text Available Background:Birth trauma and its often incorrect inference of iatrogenic causation has led to unfortunate implications for the affected child, the parents, the obstetrician and the midwife due to unwarranted medico-legal attention in our current litigious society.A more discerning evaluation of neonatal nerve palsies following labour and delivery has led to a better understanding of their aetiology with potentially more appropriate outcomes for all parties involved.

Case of Cytomegalovirus Infection Causing Isolated Oculomotor Nerve Palsy

Directory of Open Access Journals (Sweden)

Halil Sen

2014-06-01

Full Text Available The third cranial nerve is called the oculomotor nerve. The pathology is revealed by limitation of eye movement inward-up-down, mydriasis, loss of light reflex and ptosis. Oculomotor nerve pathologies are frequently seen in neurology practice and are situations that may be very difficult for differential diagnosis. Differential diagnosis first involves disqualifying intracranial etiologies by imaging because these intracranial etiologies may be situations that can result in death and should be primarily evaluated. If intracranial events are ruled out, generally rarer etiologic reasons with generally difficult differentiation should be researched. Viral infections are among the rare etiological reasons causing 3rd cranial nerve involvement. Our case was a 71-year old female with etiological research due to 3rd cranial nerve palsy. The patient with diabetes-linked immune deficiency was found to have cranial nerve involvement developed secondary to cytomegalovirus (CMV infection. We report this case as 3rd cranial nerve involvement is rarely observed developing linked to CMV infection.

Cranial nerve involvement is not common in leprosy. The fifth and seventh cranial nerves are the most commonly affected in leprosy. Herein we present a patient with Hansen disease (BL) with type I reaction who developed isolated involvement of the sixth cranial nerve leading to lateral rectus muscle palsy. He responded to timely anti-reactional therapy and it produced a good response. Careful observation of patients with lepra reaction is needed to avoid damage to important organs.

Molinari, Andrea; Ugrin, Maria Cristina

2009-12-01

Superior oblique palsy is accompanied in most cases by overaction of the muscle's ipsilateral antagonist, the inferior oblique muscle. Overaction and contracture of the ipsilateral superior rectus muscle in patients with unilateral fourth (trochlear) nerve palsy is seldom discussed in the literature. The purpose of this study is to evaluate the frequency of superior rectus muscle overaction/contracture syndrome in patients with unilateral trochlear nerve palsy. The records of 198 patients with unilateral trochlear nerve palsy examined by the authors between July 1987 and July 2008 were reviewed retrospectively. All patients underwent complete eye examination with measurement of the deviation in the 9 positions of gaze and with the head tilted to both sides in all cooperative patients. Selection criteria for superior rectus muscle overaction/contracture syndrome in these patients were as follows: vertical deviation of 15(Delta) or larger in primary position, equal or larger hypertropia with the ipsilateral forced tilt test than with the eyes looking straight ahead, more than 5(Delta) hypertropia of the affected eye in horizontal gaze to the same side, hypertropia in all upgazes, and overaction of the contralateral superior oblique muscle. Of 198 patients, 33 (16.6%) met the selection criteria for superior rectus muscle overaction/contracture syndrome. Superior rectus muscle overaction/contracture syndrome frequently occurs in unilateral superior oblique palsy.

1987-01-01

A case of the persistence of the primitive hypoglossal artery is reported, with a roentgenographic demonstration of the enlarged hypoglossal canal. A 63-year-old man was admitted to this hospital as a result of a malfunction of the ventriculo-peritoneal shunt. At the age of 51, the patient had been operated on in this hospital for an aneurysm of the right middle cerebral artery; at that time, the right primitive hypoglossal artery was observed on right carotid angiograms. On the day following admission, bilateral retrograde vertebral angiography was performed and the right persistent primitive hypoglossal artery was recognized again. Stenvers views of the skull demonstrated an enlargement of the hypoglossal canal, with a smooth sclerotic rim. High-resolution computed tomography with a contrast infusion delineated the right primitive hypoglossal artery through the enlarged hypoglossal canal. The diameter of the enlarged right hypoglossal canal and that of the left one were found to be 8 mm and 4 mm respectively on the CT. When an enlargement of the hypoglossal canal with a sclerotic rim is observed, the persistence of the primitive hypoglossal artery should be considered in the differential diagnosis. (author)

Bell's palsy is highly associated with diabetes mellitus (DM). Either the reactivation of herpes simplex virus type 1 (HSV-1) or diabetic mononeuropathy has been proposed to cause the facial paralysis observed in DM patients. However, distinguishing whether the facial palsy is caused by herpetic neuritis or diabetic mononeuropathy is difficult. We previously reported that facial paralysis was aggravated in DM mice after HSV-1 inoculation of the murine auricle. In the current study, we induced HSV-1 reactivation by an auricular scratch following DM induction with streptozotocin (STZ). Controlled animal study. Diabetes mellitus was induced with streptozotocin injection in only mice that developed transient facial nerve paralysis with HSV-1. Recurrent facial palsy was induced after HSV-1 reactivation by auricular scratch. After DM induction, the number of cluster of differentiation 3 (CD3)(+) T cells decreased by 70% in the DM mice, and facial nerve palsy recurred in 13% of the DM mice. Herpes simplex virus type 1 deoxyribonucleic acid (DNA) was detected in the facial nerve of all of the DM mice with palsy, and HSV-1 capsids were found in the geniculate ganglion using electron microscopy. Herpes simplex virus type 1 DNA was also found in some of the DM mice without palsy, which suggested the subclinical reactivation of HSV-1. These results suggested that HSV-1 reactivation in the geniculate ganglion may be the main causative factor of the increased incidence of facial paralysis in DM patients. © 2014 The American Laryngological, Rhinological and Otological Society, Inc.

This study evaluates the effect of incobotulinumtoxinA in the acute and chronic phases of facial nerve palsy after neurosurgical interventions. Patients received incobotulinumtoxinA injections (active treatment group) or standard rehabilitation treatment (control group). Functional efficacy was assessed using House-Brackmann, Yanagihara System and Sunnybrook Facial Grading scales, and Facial Disability Index self-assessment. Significant improvements on all scales were seen after 1month of incobotulinumtoxinA treatment (active treatment group, р<0.05), but only after 3months of rehabilitation treatment (control group, р<0.05). At 1 and 2years post-surgery, the prevalence of synkinesis was significantly higher in patients in the control group compared with those receiving incobotulinumtoxinA treatment (р<0.05 and р<0.001, respectively). IncobotulinumtoxinA treatment resulted in significant improvements in facial symmetry in patients with facial nerve injury following neurosurgical interventions. Treatment was effective for the correction of the compensatory hyperactivity of mimic muscles on the unaffected side that develops in the acute period of facial nerve palsy, and for the correction of synkinesis in the affected side that develops in the long-term period. Appropriate dosing and patient education to perform exercises to restore mimic muscle function should be considered in multimodal treatment. Copyright © 2017 Elsevier B.V. All rights reserved.

Saatci, I.; Sahintuerk, F.; Sennaroglu, L.; Boyvat, F.; Guersel, B.; Besim, A.

1996-01-01

The purpose of this prospective study was to define the enhancement pattern of the facial nerve in idiopathic facial paralysis (Bell's palsy) on magnetic resonance (MR) imaging with routine doses of gadolinium-DTPA (0.1 mmol/kg). Using 0.5 T imager, 24 patients were examined with a mean interval time of 13.7 days between the onset of symptoms and the MR examination. Contralateral asymptomatic facial nerves constituted the control group and five of the normal facial nerves (20.8%) showed enhancement confined to the geniculate ganglion. Hence, contrast enhancement limited to the geniculate ganglion in the abnormal facial nerve (3 of 24) was referred to a equivocal. Not encountered in any of the normal facial nerves, enhancement of other segments alone or associated with geniculate ganglion enhancement was considered to be abnormal and noted in 70.8% of the symptomatic facial nerves. The most frequently enhancing segments were the geniculate ganglion and the distal intracanalicular segment. (orig.)

2017-06-01

Full Text Available Malignant peripheral nerve sheath tumor (MPNST of oral cavity is an extremely uncommon malignancy. Less than 15 cases have been reported since 1973 though none of them describes a distant metastasis. We present a rare case of MPNST of the tongue who presented with features of hypoglossal nerve palsy. Incisional biopsy showed a malignant spindle cell tumor in the sub-epithelial connective tissue. The tumor cells were immune-positive for S-100. He underwent surgery followed by adjuvant chemo-radiation. Later the disease recurred in the form of isolated pelvic bone metastasis. Palliative chemotherapy was offered to him. With this case report we intend to refer to such unusual presentation and pattern of recurrence in a MPNST of tongue.

Selective upper airway stimulation of the hypoglossal nerve is a novel therapy option for obstructive sleep apnea. Different tongue motions were observed after surgery during active therapy. We examined tongue motions in 14 patients (mean age 51 ± 10 years) who received an implantation of an upper airway stimulation system (Inspire Medical Systems) from September 2013 to February 2014 in three different implantation centers in Germany after surgery. Sleep recording was performed preoperatively: 2 months (M02) and 6 months (M06) after surgery. There were three different tongue motions observed after surgery at 1 month (M01), M02, and M06 after surgery: bilateral protrusion (BP), right protrusion (RP), and mixed activation (MA). At M01: 10 BP, 2 RP, and 2 MA; at M02: 12 BP, 0 RP, and 2 MA; and at M06: 12 BP, 0 RP, and 2 MA could be detected. The average apnea-hypopnea index (AHI) was reduced from 32.5 ± 14.2/h before surgery to 17.9 ± 23.3/h at M02 and 14.1 ± 19.8/h at M06. An increased reduction in AHI was found in BP and RP group (Baseline: 29.6 ± 12.6/h; M02: 12.06 ± 14.1/h; M06: 9.7 ± 12.6/h) compared to the MA group (Baseline 49.6 ± 13.8/h; M02: 49.7 ± 5.1/h; M06: 40.5 ± 4.1/h). These findings suggest that the postoperative tongue motions in upper airway stimulation are associated with the therapy outcome. The stimulation electrode placement on the hypoglossal nerve for selective muscle recruitment may play a role in the mechanism of action.

Radial nerve palsy in mid/distal humeral fractures: is early exploration effective?

Science.gov (United States)

Keighley, Geffrey; Hermans, Deborah; Lawton, Vidya; Duckworth, David

2018-03-01

Radial nerve palsies are a common complication with displaced distal humeral fractures. This case series examines the outcomes of early operative exploration and decompression of the nerve with fracture fixation with the view that this provides a solid construct for optimisation of nerve recovery. A total of 10 consecutive patients with a displaced distal humeral fracture and an acute radial nerve palsy were treated by the senior author by open reduction and internal fixation of the distal humerus and exploration and decompression of the radial nerve. Motor function and sensation of the radial nerve was assessed in the post-operative period every 2 months or until full recovery of the radial nerve function had occurred. All patients (100%) had recovery of motor and sensation function of their upper limb in the radial nerve distribution over a 12-month period. Recovery times ranged between 4 and 32 weeks, with the median time to recovery occurring at 26 weeks and the average time to full recovery being 22.9 weeks. Wrist extension recovered by an average of 3 months (range 2-26 weeks) and then finger extension started to recover 2-6 weeks after this. Disability of the arm, shoulder and hand scores ranged from 0 to 11.8 at greater than 1 year post-operatively. Our study demonstrated that early operative exploration of the radial nerve when performing an open stabilization of displaced distal humeral fractures resulted in a 100% recovery of the radial nerve. © 2017 Royal Australasian College of Surgeons.

Intraneural arachnoid cyst is an extremely rare etiology of isolated cranial nerve palsy. Although seldom encountered in clinical practice, this pathology is amenable to surgical intervention. Correct identification and treatment of the cyst are required to prevent permanent nerve damage and potentially reverse the deficits. We describe a rare case of isolated third nerve palsy caused by an intraneural arachnoid cyst. A 49-year-old woman with a recent history of headaches experienced acute onset of painless left-sided third nerve palsy. According to hospital records ptosis, mydriasis, absence of adduction, elevation, and intorsion were noted in the left eye. Computed tomography and magnetic resonance imaging studies showed an extra-axial, 1-cm lesion along the left paraclinoid region, causing mild indentation on the uncus. There was dense fluid layering dependently concerning for hemorrhage, but no evidence of aneurysms. A pterional craniotomy was performed, revealing a completely intraneural arachnoid cyst in the third nerve. The cyst was successfully fenestrated. At 7-month follow-up, the left eye had recovered intact intorsion and some adduction, but the left pupil remained dilated and nonreactive. There was still no elevation and no afferent pupillary defect. Double vision persisted with partial improvement in the ptosis, opening up to more than 75% early in the day. To our knowledge, this is the first report of an intraneural arachnoid cyst causing isolated third nerve palsy. This rare pathology proves to be both a diagnostic and therapeutic challenge.

The distinction between central and peripheral facial nerve palsy can be difficult but is very important for the workup and treatment. A tumefactive demyelinating lesion (TDL) is a rare condition that can sometimes cause diagnostic difficulties due to its similarity to a brain tumour. We present a 20-year-old female patient who visited her GP with a discrete right-sided drooping corner of her mouth. The GP started treatment with oral glucorticoids because of presumed Bell's palsy and referred her to the neurology outpatient clinic. Repeated neurological examination showed central facial palsy on the right side of the face. An MRI study of the brain revealed a single large contrast-enhanced abnormality in the left hemisphere that was diagnosed as TDL after exclusion of other causes. In view of the limited number of clinical symptoms, an expectative policy was conducted. The patient recovered spontaneously and repeated MRI studies showed partial regression of TDL. TDL is often considered to be a first presentation of multiple sclerosis. Accurate analysis with MRI can help in making a diagnosis without the need for a biopsy.

Outcome of different facial nerve reconstruction techniques

Directory of Open Access Journals (Sweden)

Aboshanif Mohamed

Full Text Available Abstract Introduction: There is no technique of facial nerve reconstruction that guarantees facial function recovery up to grade III. Objective: To evaluate the efficacy and safety of different facial nerve reconstruction techniques. Methods: Facial nerve reconstruction was performed in 22 patients (facial nerve interpositional graft in 11 patients and hypoglossal-facial nerve transfer in another 11 patients. All patients had facial function House-Brackmann (HB grade VI, either caused by trauma or after resection of a tumor. All patients were submitted to a primary nerve reconstruction except 7 patients, where late reconstruction was performed two weeks to four months after the initial surgery. The follow-up period was at least two years. Results: For facial nerve interpositional graft technique, we achieved facial function HB grade III in eight patients and grade IV in three patients. Synkinesis was found in eight patients, and facial contracture with synkinesis was found in two patients. In regards to hypoglossal-facial nerve transfer using different modifications, we achieved facial function HB grade III in nine patients and grade IV in two patients. Facial contracture, synkinesis and tongue atrophy were found in three patients, and synkinesis was found in five patients. However, those who had primary direct facial-hypoglossal end-to-side anastomosis showed the best result without any neurological deficit. Conclusion: Among various reanimation techniques, when indicated, direct end-to-side facial-hypoglossal anastomosis through epineural suturing is the most effective technique with excellent outcomes for facial reanimation and preservation of tongue movement, particularly when performed as a primary technique.

Variant Anterior Digastric Muscle Transfer for Marginal Mandibular Branch of Facial Nerve Palsy

Directory of Open Access Journals (Sweden)

Matthew J. Zdilla, DC

2014-02-01

Full Text Available Summary: Marginal mandibular branch of facial nerve (MMBFN palsy is a common consequence of head and neck surgeries. MMBFN palsy results in paralysis of muscles which depress the inferior lip. Current management of MMBFN palsy involves ruination of normal neuromuscular anatomy and physiology to restore symmetry to the mouth. The article outlines the possibility to transfer variant anterior digastric musculature to accomplish reanimation of the mouth without adversely affecting normal nonvariant anatomy. The procedure may have the additional cosmetic benefit of correcting asymmetrical muscular bulk in the submental region.

Transient sixth cranial nerve palsy following orgasm abrogated by treatment with sympathomimetic amines.

Check, J H; Katsoff, B

2014-01-01

To describe a unique disorder where a transient 6th nerve palsy leading to diploplia following orgasm developed in a 28-year-old woman. This coincided with a weight gain of 100 pounds in a short time without a corresponding change in dietary habits. She was treated with the sympathomimetic amine dextroamphetamine sulfate. Indeed she immediately responded to treatment with dextroamphetamine sulfate sustained release capsules with complete resolution of the episodes of 6th nerve palsy following orgasm. The main importance of this case is that it suggests that orgasm causes a transient generalized decrease in sympathetic nervous system activity and that the achievement of an orgasm may require an increase in the sympathetic nervous system activity.

2013-12-01

The issue of phrenic nerve preservation during pneumonectomy is still an unanswered question. So far, its direct effect on immediate postoperative pulmonary lung function has never been evaluated in a prospective trial. We conducted a prospective crossover study including 10 patients undergoing pneumonectomy for lung cancer between July 2011 and July 2012. After written informed consent, all consecutive patients who agreed to take part in the study and in whom preservation of the phrenic nerve during operation was possible, were included in the study. Upon completion of lung resection, a catheter was placed in the proximal paraphrenic tissue on the pericardial surface. After an initial phase of recovery of 5 days all patients underwent ultrasonographic assessment of diaphragmatic motion followed by lung function testing with and without induced phrenic nerve palsy. The controlled, temporary paralysis of the ipsilateral hemidiaphragm was achieved by local administration of lidocaine 1% at a rate of 3 mL/h (30 mg/h) via the above-mentioned catheter. Temporary phrenic nerve palsy was accomplished in all but 1 patient with suspected catheter dislocation. Spirometry showed a significant decrease in dynamic lung volumes (forced expiratory volume in 1 second and forced vital capacity; p phrenic nerve palsy causes a significant impairment of dynamic lung volumes during the early postoperative period after pneumonectomy. Therefore, in these already compromised patients, intraoperative phrenic nerve injury should be avoided whenever possible. Copyright © 2013 The Society of Thoracic Surgeons.

Peroneal nerve palsy in traumatic knee dislocations associated with multiple ligament injuries is common. Several surgical approaches are described for this lesion with less-than-optimal outcomes. The present case represents the application of plasma rich in growth factors (PRGF) technology for the treatment of peroneal nerve palsy with drop foot. This technology has already been proven its therapeutic potential for various musculoskeletal disorders. Based on these results, we hypothesized that PRGF could stimulate the healing process of traumatic peroneal nerve palsy with drop foot. The patient was a healthy 28-year-old man. He suffered peroneal nerve palsy with drop foot after multiple ligament injuries of the knee. PRGF was prepared according to the manufactured instruction. Eleven months after the trauma with severe axonotmesis, serial intraneural infiltrations of PRGF were started using ultrasound guidance. The therapeutic effect was assessed by electromyography (EMG), echogenicity of the peroneal nerve under ultrasound (US) and manual muscle testing. Twenty-one months after the first injection, not complete but partial useful recovery is obtained. He is satisfied with walking and running without orthosis. Sensitivity demonstrates almost full recovery in the peroneal nerve distribution area. EMG controls show complete reinnervation for the peroneus longus and a better reinnervation for the tibialis anterior muscle, compared with previous examinations. Plasma rich in growth factors (PRGF) infiltrations could enhance healing process of peroneal nerve palsy with drop foot. This case report demonstrates the therapeutic potential of this technology for traumatic peripheral nerve palsy and the usefulness of US-guided PRGF. V.

Cranial nerve lessions often accompany head trauma. Nevertheless, isolated involvement of the sixth nerve without any cranial or cervical fracture is rare. Nerve injury could occur at the sites of the dural entry points and at the petrous apex during down- or upward movement of the brain caused by violent linear force to the head. Management is symptomatic. Most cases improve within three months and many resolve by six months, but spontaneous recovery does not always occur. We describe the case of a 13-year-old boy who developed isolated abducens nerve palsy after closed head trauma.

Peripheral facial nerve palsy is the commonest cranial nerve motor neuropathy. The causes range from cerebrovascular accident to iatrogenic damage, but there are few reports of facial nerve paralysis attributable to odontogenic infections. In majority of the cases, recovery of facial muscle function begins within first three weeks after onset. This article reports a unique case of 32-year-old male patient who developed facial pain followed by unilateral facial nerve paralysis due to odontogen...

The term Bell's palsy is used for the peripheral paresis of the facial nerve and is of unknown origin. Many studies have been performed to find the cause of the disease, but none has given certain evidence of the etiology. However, the majority of investigators agree that the pathophysiology of the palsy starts with the edema of the facial nerve and consequent entrapment of the nerve in the narrow facial canal in the temporal bone. In this study the authors wanted to find why the majority of the paresis are suprastapedial, i.e. why the entrapment of the nerve mainly occurs in the proximal part of the canal. For this reason they carried out anatomical measurements of the facial canal diameter in 12 temporal bones. By use of a computer program which measures the cross-sectional area from the diameter, they proved that the width of the canal is smaller at its proximal part. Since the nerve is thicker at that point because it contains more nerve fibers, the authors conclude that the discrepancy between the nerve diameter and the surrounding bony walls in the suprastapedial part of the of the canal would, in cases of a swollen nerve after inflammation, cause the facial palsy.

Fractures of the skull base can cause lower cranial nerve palsies because of involvement of the nerves as they traverse the skull. A variety of syndromes have been described, often involving multiple nerves. These are most commonly unilateral, and only a handful of cases of bilateral cranial nerve involvement have been reported. We describe a 64-year-old man with occipital condylar fracture complicated by bilateral palsies of IX and X nerves associated with dramatic physiological derangement causing severe management challenges. Apart from debilitating postural hypotension, he developed dysphagia, severe gastrointestinal dysmotility, issues with airway protection as well as airway obstruction, increased oropharyngeal secretions and variable respiratory control. This is the first report of a patient with traumatic bilateral cranial nerve IX and X nerve palsies. This detailed report and the summary of all 6 previous case reports of traumatic bilateral lower cranial nerve palsies illustrate clinical features, treatment strategies, and outcomes of these rare events.

There is no technique of facial nerve reconstruction that guarantees facial function recovery up to grade III. To evaluate the efficacy and safety of different facial nerve reconstruction techniques. Facial nerve reconstruction was performed in 22 patients (facial nerve interpositional graft in 11 patients and hypoglossal-facial nerve transfer in another 11 patients). All patients had facial function House-Brackmann (HB) grade VI, either caused by trauma or after resection of a tumor. All patients were submitted to a primary nerve reconstruction except 7 patients, where late reconstruction was performed two weeks to four months after the initial surgery. The follow-up period was at least two years. For facial nerve interpositional graft technique, we achieved facial function HB grade III in eight patients and grade IV in three patients. Synkinesis was found in eight patients, and facial contracture with synkinesis was found in two patients. In regards to hypoglossal-facial nerve transfer using different modifications, we achieved facial function HB grade III in nine patients and grade IV in two patients. Facial contracture, synkinesis and tongue atrophy were found in three patients, and synkinesis was found in five patients. However, those who had primary direct facial-hypoglossal end-to-side anastomosis showed the best result without any neurological deficit. Among various reanimation techniques, when indicated, direct end-to-side facial-hypoglossal anastomosis through epineural suturing is the most effective technique with excellent outcomes for facial reanimation and preservation of tongue movement, particularly when performed as a primary technique.

The patient was a 47-year-old man who presented with diplopia and gait instability with a gradual onset over the course of three days. Neurological examinations showed ophthalmoplegia, diminished tendon reflexes, and truncal ataxia. Tests for anti-GQ1b antibodies and several other antibodies to ganglioside complex were positive. We made a diagnosis of Fisher syndrome. After administration of intravenous immunoglobulin, the patient's symptoms gradually improved. However, bilateral facial palsy appeared during the recovery phase. Brain MRI showed intensive contrast enhancement of bilateral facial nerves. During the onset phase of facial palsy, the amplitude of the compound muscle action potential (CMAP) in the facial nerves was preserved. During the peak phase, the facial CMAP amplitude was within the lower limit of normal values, or mildly decreased. During the recovery phase, the CMAP amplitude was normalized, and the R1 and R2 responses of the blink reflex were prolonged. The delayed facial nerve palsy improved spontaneously, and the enhancement on brain MRI disappeared. Serial neurophysiological and neuroradiological examinations suggested that the main lesions existed in the proximal part of the facial nerves and the mild lesions existed in the facial nerve terminals, probably due to reversible conduction failure.

OBJECTIVE Compressive cranial nerve syndromes can be useful bedside clues to the diagnosis of an enlarging intracranial aneurysm and can also guide subsequent evaluation, as with an acute oculomotor nerve (cranial nerve [CN] III) palsy that is presumed to be a posterior communicating artery aneurysm and a surgical emergency until proven otherwise. The CN VI has a short cisternal segment from the pontomedullary sulcus to Dorello's canal, remote from most PICA aneurysms but in the hemodynamic pathway of a rupturing PICA aneurysm that projects toward Dorello's canal. The authors describe a cranial nerve syndrome for posterior inferior cerebellar artery (PICA) aneurysms that associates subarachnoid hemorrhage (SAH) and an isolated abducens nerve (CN VI) palsy. METHODS Clinical and radiological data from 106 surgical patients with PICA aneurysms (66 ruptured and 40 unruptured) were retrospectively reviewed. Data from a group of 174 patients with other aneurysmal SAH (aSAH) were analyzed in a similar manner to control for nonspecific effects of SAH. Univariate statistical analysis compared incidence and risk factors associated with CN VI palsy in subarachnoid hemorrhage. RESULTS Overall, 13 (4.6%) of 280 patients had CN VI palsy at presentation, and all of them had ruptured aneurysms (representing 13 [5.4%] of the 240 cases of ruptured aneurysms). CN VI palsies were observed in 12 patients with ruptured PICA aneurysms (12/66 [18.1%]) and 1 patient with other aSAH (1/174 [0.1%], p < 0.0001). PICA aneurysm location in ruptured aneurysms was an independent predictor for CN VI palsy on multivariate analysis (p = 0.001). PICA aneurysm size was not significantly different in patients with or without CN VI palsy (average size 4.4 mm and 5.2 mm, respectively). Within the PICA aneurysm cohort, modified Fisher grade (p = 0.011) and presence of a thick cisternal SAH (modified Fisher Grades 3 and 4) (p = 0.003) were predictors of CN VI palsy. In all patients with ruptured PICA

Full Text Available Monteggia fractures are rare in children, and subtle radial head dislocations, with minor plastic deformation of the ulna, may be missed in up to a third of cases. Complications of Monteggia fractures-dislocations include persistent radial head dislocation, forearm deformity, elbow stiffness, and nerve palsies at the time of presentation. An unusual case of median nerve palsy following elastic stable intramedullary nailing of a type I Monteggia lesion in a 6-year-old girl is presented, and we highlight that, although most nerve palsies associated with a Monteggia fracture-dislocations are treated expectantly in children, early intervention here probably provided the best outcome.

A 4 year-old girl was referred to our hospital after have suffered a severe accident. The patient was diagnosed with complete third nerve palsy in her right eye and Purtscher retinopathy in her left eye. Purtscher retinopathy is a rare condition. The diagnosis is made on clinical ground and its treatment is not well defined although it is believed that systemic steroids could improve the visual outcome. Traumatic third nerve palsy has a poor spontaneous recovery. The use of botulinum toxin might be useful in children to improve the recovery rate, maintaining binocularity, and avoiding amblyopia in other cases.

Objectives  This study aimed at evaluating facial nerve outcomes in vestibular schwannoma patients presenting with preoperative facial nerve palsy. Design  A retrospective review. Setting  Single-institution cohort. Participants  Overall, 368 consecutive patients underwent vestibular schwannoma resection. Patients with prior microsurgery or radiosurgery were excluded. Main Outcome Measures  Incidence, House-Brackmann grade. Results  Of 368 patients, 9 had confirmed preoperative facial nerve dysfunction not caused by prior treatment, for an estimated incidence of 2.4%. Seven of these nine patients had Koos grade 4 tumors. Mean tumor diameter was 3.0 cm (range: 2.1-4.4 cm), and seven of nine tumors were subtotally resected. All nine patients were followed up clinically for ≥ 6 months. Of the six patients with a preoperative House-Brackmann grade of II, two improved to grade I, three were stable, and one patient worsened to grade III. Of the three patients with grade III or worse, all remained stable at last follow-up. Conclusions  Preoperative facial nerve palsy is rare in patients with vestibular schwannoma; it tends to occur in patients with relatively large lesions. Detailed long-term outcomes of facial nerve function after microsurgical resection for these patients have not been reported previously. We followed nine patients and found that eight (89%) of the nine patients had either stable or improved facial nerve outcomes after treatment. Management strategies varied for these patients, including rates of subtotal versus gross-total resection and the use of stereotactic radiosurgery in patients with residual tumor. These results can be used to help counsel patients preoperatively on expected outcomes of facial nerve function after treatment.

To assess and grade facial nerve dysfunction according to the extent of facial paralysis in the clinical course of acupuncture treatment for Bell's palsy, and to observe the interrelationship between the grade, the efficacy and the period of treatment, as well as the effect on prognosis. The authors employed the House-Brackmann scale, a commonly used evaluation scale for facial paralysis motor function, and set standards for eye fissure and lips. According to the improved scale, the authors assessed and graded the degree of facial paralysis in terms of facial nerve dysfunction both before and after treatment. The grade was divided into five levels: mild, moderate, moderately severe, severe dysfunction and complete paralysis. The authors gave acupuncture treatment according to the state of the disease without artificially setting the treatment period. The observation was focused on the efficacy and the efficacy was evaluated throughout the entire treatment process. Fifty-three cases out of 68 patients with Bell's palsy were cured and the overall rate of efficacy was 97%. Statistically significant differences (PBell's palsy in terms of severity of facial nerve dysfunction. Efficacy is reduced in correlation with an increase in facial nerve dysfunction, and the period of treatment varies in need of different levels of facial nerve dysfunction. It is highly necessary to assess and grade patients before observation and treatment in clinical study, and choose corresponding treatment according to severity of damage of the disease.

Little is known about the reasons for occurrence of facial nerve palsy after removal of cerebellopontine angle tumors. Since the intra-arachnoidal portion of the facial nerve is considered to be so vulnerable that even the slightest tension or pinch may result in ruptured axons, we tested whether a graded stretch or controlled crush would affect the postoperative motor performance of the facial (vibrissal) muscle in rats. Thirty Wistar rats, divided into five groups (one with intact controls and four with facial nerve lesions), were used. Under inhalation anesthesia, the occipital squama was opened, the cerebellum gently retracted to the left, and the intra-arachnoidal segment of the right facial nerve exposed. A mechanical displacement of the brainstem with 1 or 3 mm toward the midline or an electromagnet-controlled crush of the facial nerve with a tweezers at a closure velocity of 50 and 100 mm/s was applied. On the next day, whisking motor performance was determined by video-based motion analysis. Even the larger (with 3 mm) mechanical displacement of the brainstem had no harmful effect: The amplitude of the vibrissal whisks was in the normal range of 50°-60°. On the other hand, even the light nerve crush (50 mm/s) injured the facial nerve and resulted in paralyzed vibrissal muscles (amplitude of 10°-15°). We conclude that, contrary to the generally acknowledged assumptions, it is the nerve crush but not the displacement-induced stretching of the intra-arachnoidal facial trunk that promotes facial palsy after cerebellopontine angle surgery in rats.

Full Text Available Tendon transfers for radial nerve palsy is a common operation with good results. We did a retrospective study on twenty patients with radial nerve palsy who underwent tendon transfer surgery and recovered between January 2008 and December 2012. Outcomes measured were motor power of wrist extension, finger extension, grip strength and DASH scores. There was significant improvement of motor power of wrist and finger extension between the preoperative period and three months post-operatively, between the pre operative period and six months post operatively and between three and six months postoperatively (p = 0.0005. Grip strength improved significantly as well between preoperative, three and six months postoperatively (p = 0.0005. DASH scores reflecting patient satisfaction at six months postoperatively showed only mild or moderate difficulty of function.

Resolution of oculomotor nerve palsy (ONP) after clipping of posterior communicating artery (PCoA) aneurysms has been well documented. However, whether additional decompression of the oculomotor nerve via aneurysm sac dissection or resection is superior to pure aneurysm clipping is the subject of much debate. Therefore, the objective in the present investigation was to analyze the influence of surgical strategy--specifically, clipping with or without aneurysm dissection--on ONP resolution. Between June 1999 and December 2010, 18 consecutive patients with ruptured and unruptured PCoA aneurysms causing ONP were treated at the authors' institution. Oculomotor nerve palsy was evaluated on admission and at follow-up. The electronic database MEDLINE was searched for additional data in published studies of PCoA aneurysms causing ONP. Two reviewers independently extracted data. Overall, 8 studies from the literature review and 6 patients in the current series (121 PCoA aneurysms) met the study inclusion criteria. Ninety-four aneurysms were treated with simple aneurysm neck clipping and 27 with clipping plus aneurysm sac decompression. The surgical strategy, simple aneurysm neck clipping versus clipping plus oculomotor nerve decompression, had no effect on full ONP resolution on univariate (p = 0.5) and multivariate analyses. On multivariate analysis, patients with incomplete ONP at admission were more likely to have full resolution of the palsy than were those with complete ONP at admission (p = 0.03, OR = 4.2, 95% CI 1.1-16). Data in the present study indicated that ONP caused by PCoA aneurysms improves after clipping without and with oculomotor nerve decompression. The resolution of ONP is inversely associated with the initial severity of ONP.

Vacher, C; Cyna-Gorse, F

Motor innervation of the face depends on the facial nerve for the mobility of the face, on the mandibular nerve, third branch of the trigeminal nerve, which gives the motor innervation of the masticator muscles, and the hypoglossal nerve for the tongue. In case of facial paralysis, the most common palliative surgical techniques are the lengthening temporalis myoplasty (the temporal is innervated by the mandibular nerve) and the hypoglossal-facial anastomosis. The aim of this work is to describe the surgical anatomy of these three nerves and the radiologic anatomy of the facial nerve inside the temporal bone. Then the facial nerve penetrates inside the parotid gland giving a plexus. Four branches of the facial nerve leave the parotid gland: they are called temporal, zygomatic, buccal and marginal which give innervation to the cutaneous muscles of the face. Mandibular nerve gives three branches to the temporal muscles: the anterior, intermediate and posterior deep temporal nerves which penetrate inside the deep aspect of the temporal muscle in front of the infratemporal line. The hypoglossal nerve is only the motor nerve to the tongue. The ansa cervicalis, which is coming from the superficial cervical plexus and joins the hypoglossal nerve in the submandibular area is giving the motor innervation to subhyoid muscles and to the geniohyoid muscle.

[Facial palsy].

Cavoy, R

2013-09-01

Facial palsy is a daily challenge for the clinicians. Determining whether facial nerve palsy is peripheral or central is a key step in the diagnosis. Central nervous lesions can give facial palsy which may be easily differentiated from peripheral palsy. The next question is the peripheral facial paralysis idiopathic or symptomatic. A good knowledge of anatomy of facial nerve is helpful. A structure approach is given to identify additional features that distinguish symptomatic facial palsy from idiopathic one. The main cause of peripheral facial palsies is idiopathic one, or Bell's palsy, which remains a diagnosis of exclusion. The most common cause of symptomatic peripheral facial palsy is Ramsay-Hunt syndrome. Early identification of symptomatic facial palsy is important because of often worst outcome and different management. The prognosis of Bell's palsy is on the whole favorable and is improved with a prompt tapering course of prednisone. In Ramsay-Hunt syndrome, an antiviral therapy is added along with prednisone. We also discussed of current treatment recommendations. We will review short and long term complications of peripheral facial palsy.

Basic fibroblast growth factor (bFGF) promotes the regeneration of denervated nerves. The aim of this study was to evaluate the regeneration-facilitating effects of novel facial nerve decompression surgery using bFGF in a gelatin hydrogel in patients with severe Bell palsy. Prospective clinical study. Tertiary referral center. Twenty patients with Bell palsy after more than 2 weeks following the onset of severe paralysis were treated with the new procedure. The facial nerve was decompressed between tympanic and mastoid segments via the mastoid. A bFGF-impregnated biodegradable gelatin hydrogel was placed around the exposed nerve. Regeneration of the facial nerve was evaluated by the House-Brackmann (H-B) grading system. The outcomes were compared with the authors' previous study, which reported outcomes of the patients who underwent conventional decompression surgery (n = 58) or conservative treatment (n = 43). The complete recovery (H-B grade 1) rate of the novel surgery (75.0%) was significantly better than the rate of conventional surgery (44.8%) and conservative treatment (23.3%). Every patient in the novel decompression surgery group improved to H-B grade 2 or better even when undergone between 31 and 99 days after onset. Advantages of this decompression surgery are low risk of complications and long effective period after onset of the paralysis. To the authors' knowledge, this is the first clinical report of the efficacy of bFGF using a new drug delivery system in patients with severe Bell palsy.

Functional anatomy of the hypoglossal innervated muscles of the rat tongue: a model for elongation and protrusion of the mammalian tongue.

McClung, J R; Goldberg, S J

This anatomical investigation in the rat was designed to illustrate the detailed organization of the tongue's muscles and their innervation in order to elucidate the actions of the muscles of the higher mammalian tongue and thereby clarify the protrusor subdivision of the hypoglossal-tongue complex. The hypoglossal innervated, extrinsic styloglossus, hyoglossus, and genioglossus and the intrinsic transversus, verticalis and longitudinalis linguae muscles were observed by microdissection and analysis of serial transverse-sections of the tongue. Sihler's staining technique was applied to whole rat tongues to demonstrate the hypoglossal nerve branching patterns. Dissections of the tongue demonstrate the angles at which the extrinsic muscles act on the base of the tongue. The Sihler stained hypoglossal nerves demonstrate branches to the styloglossus and hyoglossus emanating from its lateral division while branches to the genioglossus muscle exit from its medial division. The largest portions of both XIIth nerve divisions can be seen to enter the body of the tongue to innervate the intrinsic muscles. Transverse sections of the tongue demonstrate the organization of the intrinsic muscle fibers of the tongue. Longitudinal muscle fibers run along the entire circumference of the tongue. Alternating sheets of transverse lingual and vertical lingual muscles can be observed to insert into the circumference of the tongue. Most importantly in clarifying tongue protrusion, we demonstrate the transversus muscle fibers enveloping the most superior and inferior portions of the longitudinalis muscles. Longitudinal muscle fascicles are completely encircled and thus are likely to be compressed by transverse muscle fascicles resulting in elongation of the tongue. We discuss our findings in relation to biomechanical studies, that describe the tongue as a muscular hydrostat and thereby define the "elongation-protrusion apparatus" of the mammalian tongue. In so doing, we clarify the

Combined Ipsilateral Oculomotor Nerve Palsy and Contralateral Downbeat Nystagmus in a Case of Cerebral Infarction

Directory of Open Access Journals (Sweden)

Kosuke Matsuzono

2014-04-01

Full Text Available We report a patient with acute cerebral infarction of the left paramedian thalamus, upper mesencephalon and cerebellum who exhibited ipsilateral oculomotor nerve palsy and contralateral downbeat nystagmus. The site of the infarction was considered to be the paramedian thalamopeduncular and cerebellar regions, which are supplied by the superior cerebellar artery containing direct perforating branches or both the superior cerebellar artery and the superior mesencephalic and posterior thalamosubthalamic arteries. Contralateral and monocular downbeat nystagmus is very rare. Our case suggests that the present downbeat nystagmus was due to dysfunction of cerebellar-modulated crossed oculovestibular fibers of the superior cerebellar peduncle or bilateral downbeat nystagmus with one-sided oculomotor nerve palsy.

Transient Femoral Nerve Palsy Complicating “Blind” Transversus Abdominis Plane Block

2013-01-01

Full Text Available We present two cases of patients who reported quadriceps femoris weakness and hypoesthesia over the anterior thigh after an inguinal hernia repair under transversus abdominis plane (TAP block. Transient femoral nerve palsy is the result of local anesthetic incorrectly injected between transversus abdominis muscle and transversalis fascia and pooling around the femoral nerve. Although it is a minor and self-limiting complication, it requires overnight hospital stay and observation of the patients. Performing the block under ultrasound guidance and injecting the least volume of local anesthetic required are ways of minimizing its incidence.

Concurrent Rotator Cuff Tear and Axillary Nerve Palsy Associated with Anterior Dislocation of the Shoulder and Large Glenoid Rim Fracture: A “Terrible Tetrad”

2014-01-01

Full Text Available We present a case of concurrent rotator cuff tear and axillary nerve palsy resulting from anterior dislocation of the shoulder and a large glenoid rim fracture—a “terrible tetrad.” A 61-year-old woman fell on her right shoulder. Radiographs showed anterior dislocation of the shoulder with a glenoid rim fracture, and an MRI two months after injury revealed a rotator cuff tear. Upon referral to our hospital, physical and electrophysiological examinations revealed axillary nerve palsy. The axillary nerve palsy was incomplete and recovering, and displacement of the glenoid rim fracture was minimal and already united; therefore, we surgically repaired only the rotator cuff tear three months after injury. The patient recovered satisfactorily following the operation. In patients whose axillary nerve palsy is recovering, surgeons should consider operating on rotator cuff tears in an attempt to prevent rotator cuff degeneration.

1976-10-01

Three cases of bilateral traumatic abducens nerve palsy were presented and the mechanism of damage to the abducens nerve was discussed in relation to the analysis of traumatic force at the time of impact and topographical anatomy of the abducens nerve in detail. Case 1. A 70 year old man sustained a traffic accident with one hour loss of consciousness. Physical examination revealed a contused area on the medial side of his right forehead. Neurological examination revealed bilateral abducens nerve palsy (Fig. 1). There were no ther cranial nerve abnormalities. Roentgenograms of the skull, including views of the base and orbit showed no fracture. At follow up examination 12 months later, bilateral Duane's retraction syndrome could be noticed with slight increase in size of the pupil on each side of lateral gaze (Fig. 2). Case 2. A 32 year old women sustained a traffic accident with 31 days of loss of consciousness. At the time of admission, bilateral abducens nerve palsy and slight left hemiparesis were noticed in semicomatose condition. Right carotid angiogtam showed no evidence of intracranial hematoma. One month later, the right eye began to abduct and 2 months later, the left eye began to abduct. Three months after the injury, bilateral abducens nerve palsy could no longer be demonstrated. No retraction syndrome was observed during this period. Case 3. A 3 year old boy sustained a traffic accident with 32 days of loss of consciousness. At the time of admission, neurological examination showed bilateral abducens palsy and left sided decerebrate posture in comatose condition. At the time of discharge 3 months after admission, bilateral abducens palsy, right hemiataxia, left spastic hemiparesis and scanning speach were noticed. Three months later, right eye began to abduct and 4 months later, the left eye began to abduct. At follow up examination 6 months later, there was no evidence of abducens nerve palsy. Topographical details of anatomy of the abducens nerve are

A 62-year-old man with acute paraplegia was transferred to our hospital. He had flaccid paraplegia and multiple cranial nerve palsies, such as mydriasis of the left pupil, abduction palsy of the left eye, hoarseness and dysphagia, but no meningeal irritation signs. MRI of the spinal canal showed swellings of the conus medullaris and the cauda equine, and also contrast enhancement of the spinal meninges. The cerebrospinal fluid (CSF) showed pleocytosis and protein increment. The lymph node was swollen in his right axilla. The biopsy specimen from the right axillary lymph node revealed metastasis of malignant melanoma histologically. Careful check-up of his whole body found a malignant melanoma in the subungual region of the right ring finger. Repeated cytological examination revealed melanoma cells in the CSF, confirming the diagnosis of leptomeningeal melanomatosis. His consciousness was gradually deteriorated. His family members chose supportive care instead of chemotherapy or surgical therapy after full information about his conditions. Finally, he died 60 days after transfer to our hospital. This is a rare case of leptomenigeal melanomatosis presenting with acute paraplegia and multiple cranial nerve palsies. Careful follow-up and repeated studies are vital for the early diagnosis of leptomenigeal melanomatosis in spite of atypical clinical presentation.

Full Text Available Aims. To report the results of lateral rectus muscle recession, medial rectus muscle resection, and superior oblique muscle transposition in the restoration and maintenance of ocular alignment in primary position for patients with total third-nerve palsy. Methods. The medical records of patients who underwent surgery between March 2007 and September 2011 for total third-nerve palsy were reviewed. All patients underwent a preoperative assessment, including a detailed ophthalmologic examination. Results. A total of 6 patients (age range, 14–45 years were included. The median preoperative horizontal deviation was 67.5 Prism Diopter (PD (interquartile range [IQR] 57.5–70 and vertical deviation was 13.5 PD (IQR 10–20. The median postoperative horizontal residual exodeviation was 8.0 PD (IQR 1–16, and the vertical deviation was 0 PD (IQR 0–4. The median correction of hypotropia following superior oblique transposition was 13.5 ± 2.9 PD (range, 10–16. All cases were vertically aligned within 5 PD. Four of the six cases were aligned within 10 PD of the horizontal deviation. Adduction and head posture were improved in all patients. All patients gained new area of binocular single vision in the primary position after the operation. Conclusion. Lateral rectus recession, medial rectus resection, and superior oblique transposition may be used to achieve satisfactory cosmetic and functional results in total third-nerve palsy.

Ultrasound-Guided Interscalene Catheter Complicated by Persistent Phrenic Nerve Palsy

2018-01-01

Full Text Available A 76-year-old male presented for reverse total shoulder arthroplasty (TSA in the beach chair position. A preoperative interscalene nerve catheter was placed under direct ultrasound-guidance utilizing a posterior in-plane approach. On POD 2, the catheter was removed. Three weeks postoperatively, the patient reported worsening dyspnea with a subsequent chest X-ray demonstrating an elevated right hemidiaphragm. Pulmonary function testing revealed worsening deficit from presurgical values consistent with phrenic nerve palsy. The patient decided to continue conservative management and declined further invasive testing or treatment. He was followed for one year postoperatively with moderate improvement of his exertional dyspnea over that period of time. The close proximity of the phrenic nerve to the brachial plexus in combination with its frequent anatomical variation can lead to unintentional mechanical trauma, intraneural injection, or chemical injury during performance of ISB. The only previously identified risk factor for PPNP is cervical degenerative disc disease. Although PPNP has been reported following TSA in the beach chair position without the presence of a nerve block, it is typically presumed as a complication of the interscalene block. Previously published case reports and case series of PPNP complicating ISBs all describe nerve blocks performed with either paresthesia technique or localization with nerve stimulation. We report a case of a patient experiencing PPNP following an ultrasound-guided placement of an interscalene nerve catheter.

Management of synkinesis and asymmetry in facial nerve palsy: a review article.

Science.gov (United States)

Pourmomeny, Abbas Ali; Asadi, Sahar

2014-10-01

The important sequelae of facial nerve palsy are synkinesis, asymmetry, hypertension and contracture; all of which have psychosocial effects on patients. Synkinesis due to mal regeneration causes involuntary movements during a voluntary movement. Previous studies have advocated treatment using physiotherapy modalities alone or with exercise therapy, but no consensus exists on the optimal approach. Thus, this review summarizes clinical controlled studies in the management of synkinesis and asymmetry in facial nerve palsy. Case-controlled clinical studies of patients at the acute stage of injury were selected for this review article. Data were obtained from English-language databases from 1980 until mid-2013. Among 124 articles initially captured, six randomized controlled trials involving 269 patients were identified with appropriate inclusion criteria. The results of all these studies emphasized the benefit of exercise therapy. Four studies considered electromyogram (EMG) biofeedback to be effective through neuromuscular re-education. Synkinesis and inconsistency of facial muscles could be treated with educational exercise therapy. EMG biofeedback is a suitable tool for this exercise therapy.

Theresa Krätzig

Full Text Available Our aim was to identify the impact of different surgical strategies on the incidence of C5 palsy.Degenerative cervical spinal stenosis is a steadily increasing morbidity in the ageing population. Postoperative C5 nerve root palsy is a common complication with severe impact on the patients´ quality of life.We identified 1708 consecutive patients who underwent cervical decompression surgery due to degenerative changes. The incidence of C5 palsy and surgical parameters including type and level of surgery were recorded to identify predictors for C5 nerve palsy.The overall C5 palsy rate was 4.8%, with 18.3% of cases being bilateral. For ACDF alone the palsy rate was low (1.13%, compared to 14.0% of C5 palsy rate after corpectomy. The risk increased with extension of the procedures. Hybrid constructs with corpectomy plus ACDF at C3-6 showed significantly lower rates of C5 palsy (10.7% than corpectomy of two vertebrae (p = 0.005. Multiple regression analysis identified corpectomy of C4 or C5 as a significant predictor. We observed a lower overall incidence for ventral (4.3% compared to dorsal (10.9% approaches (p<0.001. When imaging detected a postoperative shift of the spinal cord at index segment C4/5, palsy rate increased significantly (33.3% vs. 12.5%, p = 0.034.Extended surgical strategies, such as dorsal laminectomies, multilevel corpectomies and procedures with extensive spinal cord shift were shown to display a high risk of C5 palsy. The use of extended procedures should therefore be employed cautiously. Switching to combined surgical methods like ACDF plus corpectomy can reduce the rate of C5 palsy.

Low Median Nerve Palsy as Initial Manifestation of Churg-Strauss Syndrome.

2017-06-01

Anterior interosseous nerve (AIN) syndrome is typically characterized by forearm pain and partial or complete dysfunction of the AIN-innervated muscles. Although the exact etiology and pathophysiology of the disorder remain unclear, AIN syndrome is increasingly thought to be an inflammatory condition of the nerve rather than a compressive neuropathy because the symptoms often resolve spontaneously following prolonged observation. However, peripheral neuropathy can be 1 of the first symptoms of systemic vasculitis that needs early systemic immunotherapy to prevent extensive nerve damage. Churg-Strauss syndrome (CSS; eosinophilic granulomatosis with polyangiitis) is 1 type of primary systemic vasculitis that frequently damages the peripheral nervous system. CSS-associated neuropathy usually involves nerves of the lower limb, and few studies have reported on the involvement of the upper limb alone. We report on a rare case of low median nerve palsy as the initial manifestation of CSS. The patient recovered well with early steroid treatment for primary systemic vasculitis.

Cat scratch disease is a common infectious disorder caused by Bartonella henselae that is transmitted primarily by kittens. It typically exhibits a benign and self-limiting course of subacute regional lymphadenopathy and fever lasting two to eight weeks. The most severe complication of cat scratch disease is involvement of the nervous system, such as encephalitis, meningitis, and polyneuritis. Peripheral facial nerve palsy associated with Bartonella infection is rare; few reported pediatric and adult cases exist and the precise pathogenesis is unknown. A previously healthy 7-year-old boy presented with fever, cervical lymphadenopathy, and peripheral facial nerve palsy associated with serologically confirmed cat scratch disease. The stapedius muscle reflex was absent on the left side and brain magnetic resonance imaging revealed a mass lesion at the left internal auditory meatus. The patient's symptoms and imaging findings were gradually resolved after the antibiotics and corticosteroids treatment. The suspected granulomatous lesion was considered to have resulted from the host's immune reaction to Bartonella infection and impaired the facial nerve. This is the first case report providing direct evidence of peripheral facial nerve palsy caused by a suspected granulomatous lesion associated with cat scratch disease and its treatment course.

We performed Gd-DTPA-enhanced magnetic resonance imaging (MRI) examinations at several stages in 40 patients with peripheral facial nerve palsy (Bell's palsy and Ramsay-Hunt syndrome). In 38 of the 40 patients, one and more enhanced region could be seen in certain portion of the facial nerve in the temporal bone on the affected side, whereas no enhanced regions were seen on the intact side. Correlations between the timing of the MRI examination and the location of the enhanced regions were analysed. In all 6 patients examined by MRI within 5 days after the onset of facial nerve palsy, enhanced regions were present in the meatal portion. In 3 of the 8 patients (38%) examined by MRI 6 to 10 days after the onset of facial palsy, enhanced areas were seen in both the meatal and labyrinthine portions. In 8 of the 9 patients (89%) tested 11 to 20 days after the onset of palsy, the vertical portion was enhanced. In the 12 patients examined by MRI 21 to 40 days after the onset of facial nerve palsy, the meatal portion was not enhanced while the labyrinthine portion, the horizontal portion and the vertical portion were enhanced in 5 (42%), 8 (67%) and 11 (92%), respectively. Enhancement in the vertical portion was observed in all 5 patients examined more than 41 days after the onset of facial palsy. These results suggest that the central portion of the facial nerve in the temporal bone tends to be enhanced in the early stage of facial nerve palsy, while the peripheral portion is enhanced in the late stage. These changes of Gd-DTPA enhanced regions in the facial nerve may suggest dromic degeneration of the facial nerve in peripheral facial nerve palsy. (author)

2017-04-01

Neuralgic Amyotrophy (NA) or Parsonage-Turner syndrome is an idiopathic neuropathy commonly affecting the brachial plexus. Associated phrenic nerve involvement, though recognised, is thought to be very rare. We present a case series of four patients (all male, mean age 53) presenting with dyspnoea preceded by severe self-limiting upper limb and shoulder pain, with an elevated hemi-diaphragm on clinical examination and chest X-ray. Neurological examination of the upper limb at the time of presentation was normal. Diaphragmatic fluoroscopy confirmed unilateral diaphragmatic paralysis. Pulmonary function testing demonstrated characteristic reduction in forced vital capacity between supine and sitting position (mean 50%, range 42-65% predicted, mean change 23%, range 22-46%), reduced maximal inspiratory pressures (mean 61%, range 43-86% predicted), reduced sniff nasal inspiratory pressure (mean 88.25, range 66-109 cm H 2 O) and preserved maximal expiratory pressure (mean 107%, range 83-130% predicted). Phrenic nerve conduction studies confirmed phrenic nerve palsy. All patients were managed conservatively. Follow-up ranged from 6 months to 3 years. Symptoms and lung function variables normalised in three patients and improved significantly in the fourth. The classic history of severe ipsilateral shoulder and upper limb neuromuscular pain should be elicited and thus NA considered in the differential for a unilateral diaphragmatic paralysis, even in the absence of neurological signs. Parsonage-Turner syndrome is likely to represent a significantly under-diagnosed aetiology of phrenic nerve palsy. Conservative management as opposed to surgical intervention is advocated as most patients demonstrate gradual resolution over time in this case series.

The purpose of this study was to evaluate the causes and ophthalmologic outcome of oculomotor nerve palsy or paresis in children younger than 8 years of age. Patients evaluated between 1985 and 1997 were retrospectively reviewed. Data analyzed included vision, residual strabismus after surgery, aberrant reinnervation, binocular function, and anisometropia. Long-term outcome was assessed in patients followed-up longer than 6 months. Forty-one patients were identified. The most frequent causes were congenital (39%), traumatic (37%), and neoplastic (17%). Visual acuities were reduced in 71% of patients at the time of the initial visit. Long-term outcome could be assessed in 20 of the 41 patients (49%), with a mean follow-up of 3.6 years (range, 0.5 to 13 years). Visual acuities were reduced because of amblyopia in 35% and nonamblyopic factors in 25% of patients in the long-term outcome group at last follow-up. The best response to amblyopia therapy was in the congenital group, in which all patients improved to normal visual acuity. Strabismus surgery was performed on 8 of 20 children (40%) followed-up, none of whom demonstrated measurable stereopsis after operation despite improved alignment. Aberrant reinnervation was present in 9 of 20 patients (45%). Only 3 patients fully recovered from their oculomotor nerve injuries, and these were the only patients to regain measurable stereopsis. The causes in those 3 patients were congenital, traumatic, and neoplastic. Oculomotor nerve palsy/paresis is associated with poor visual and sensorimotor outcome in children younger than 8 years of age. The best ophthalmologic outcome was in the resolved cases (3 of 20; 15%). Amblyopia therapy was most effective with congenital causes, but treatment results were poor with other causes. Young children with posttraumatic and postneoplastic oculomotor nerve injuries demonstrated the worst ophthalmologic outcomes.

The aim of the study was to test the feasibility of the tractography technique based on diffusion-tensor imaging (DTI) for the assessment of small infarcts involving the brainstem. A patient who presented with an isolated left third cranial nerve palsy underwent magnetic resonance examination. Images were obtained by use of a whole-body, 1.5-T imager. Data were transferred to an off-line workstation for fiber tracking. The conventional diffusion-weighted imaging (DWI) performed using a 5 mm slice thickness could only depict an equivocal hyperintensity lesion located at the left paramedian midbrain. An additional thin-slice DTI was performed immediately after the initial DWI using a 3 mm slice thickness and was able to delineate the lesion more clearly. Image postprocessing of thin-slice DTI data revealed that the lesion location involved the course of the third cranial nerve tract, corresponding with the patient's clinical symptoms. The tractography technique can be applied to assess fine neuronal structures of the brainstem, enabling direct clinicoradiological correlation of small infarcts involving this region. (orig.)

Since 1907 a variety of muscle transposition procedures for the treatment of abducens nerve palsy has been established internationally. Full tendon transposition of the vertical rectus muscle was initially described by O'Connor 1935 and then augmented by Foster 1997 with addition of posterior fixation sutures on the vertical rectus muscle. Full tendon transposition augmented by Foster belongs to the group of the most powerful surgical techniques to improve the abduction. Purpose of this study was to evaluate the results of full tendon vertical rectus transposition augmented with lateral fixation suture for patients with abducens nerve palsy. Full tendon transpositions of vertical rectus muscles augmented with posterior fixation suture was performed in 2014 on five patients with abducens nerve palsy. Two of the patients received Botox injections in the medial rectus muscle: one of them three months after the surgery and another during the surgery. One of the patients had a combined surgery of the horizontal muscles one year before. On three of the patients, who received a pure transposition surgery, the preoperative deviation at the distance (mean: + 56.6 pd; range: + 40 to + 80 pd) was reduced by a mean of 39.6 pd (range 34 to 50 pd), the abduction was improved by a mean of 3 mm (range 2 to 4 mm). The other two patients, who received besides the transposition procedure additional surgeries of the horizontal muscles, the preoperative deviation at the distance (+ 25 and + 126 pd respectively) was reduced by 20 and 81 pd respectively. The abduction was improved by 4 and 8 mm respectively. After surgery two patients developed a vertical deviation with a maximum of 4 pd. None of the patients had complications or signs of anterior segment ischemia. The elevation and/or depression was only marginally affected. There was no diplopia in up- or downgaze. Full tendon transposition of vertical rectus muscles, augmented with lateral posterior fixation suture is

The outcome of severe peripheral nerve injuries requiring surgical repair (transection and suture) is usually poor. Recent work suggests that direct suture of nerves increases collagen production and provides unfavourable conditions for a proper axonal regrowth. We tested whether entubulation of the hypoglossal nerve into a Y-tube conduit connecting it with the zygomatic and buccal facial nerve branches would improve axonal pathfinding at the lesion site, quality of muscle reinnervation and recovery of vibrissal whisking. For hypoglossal-facial anastomosis (HFA) over a Y-tube (HFA-Y-tube) the proximal stump of the hypoglossal nerve was entubulated and sutured into the long arm of a Y-tube (isogeneic abdominal aorta with its bifurcation). The zygomatic and buccal facial branches were entubulated and sutured to the short arms of the Y-tube. Restoration of vibrissal motor performance, degree of collateral axonal branching at the lesion site and quality of neuro-muscular junction (NMJ) reinnervation were compared to animals receiving HFA-Coaptation (no entubulation) after 4 months. HFA-Y-tube reduced collateral axonal branching. However it failed to reduce the proportion of polyinnervated NMJ and did not improve functional outcome when compared to HFA-Coaptation. Elimination of compression by tightly opposed nerve fragments improved axonal pathfinding. However, biometric analysis of vibrissae movements did not show positive effects suggesting that polyneuronal reinnervation - rather than collateral branching - may be the critical limiting factor. Since polyinnervation of muscle fibers is activity-dependent and can be manipulated, the present findings raise hopes that clinically feasible and effective therapies after HFA could be soon designed and tested.

Sixth nerve palsy is a common complication of endovascular treatment for carotid-cavernous fistulas (CCF). Two hypotheses are evoked: the spontaneous venous congestion into the cavernous sinus and the direct compression of the nerve by the embolic agent into the cavernous sinus. Nevertheless, the evidence is still uncertain. Knowing the vicinity of the sixth nerve with the inferior petrosal sinus (IPS) in the Dorello canal, we hypothesized that the recanalization of the IPS increased the risk of nerve damage. We analyzed a prospective database of patients treated for CCFs from March 2009 to April 2016. We excluded patients who did not need treatment, cases of high-flow CCF, and patients lost to follow-up, obtaining a homogeneous population of 82 patients with indirect CCFs. This population was divided in 2 groups: patients without new-onset/worsening of sixth nerve palsy and patients with this postprocedural complication. Our main endpoints were the potential differences between patients with or without recanalization of IPS and between those who underwent or not an embolization with Onyx-18. We did not find any statistically meaningful difference between the 2 groups concerning the necessity of IPS recanalization (P > 0.999, odds ratio 0.97, 95% confidence interval 0.32-2.96) or with the use of Onyx-18 as an embolic agent (P = 0.56; odds ratio 1.41, 95% confidence interval 0.41-2.45). The recanalization of a thrombosed IPS does not increase the risk of procedural sixth nerve damage. The initial injury seems to relate with development/worsening of a sixth nerve palsy.

Methanol is generally known to cause visual impairment and various systemic manifestations. There are a few reported specific findings for methanol intoxication on magnetic resonance imaging (MRI) of the brain. A case is reported of unilateral blindness with third cranial nerve palsy oculus sinister (OS) after the ingestion of methanol. Unilateral damage of the retina and optic nerve were confirmed by fundoscopy, flourescein angiography, visual evoked potential and electroretinogram. The optic nerve and extraocular muscles (superior rectus, medial rectus, inferior rectus and inferior oblique muscle) were enhanced by gadolinium-DTPA on MRI of the orbit. This is the first case report of permanent monocular blindness with confirmed unilateral damage of the retina and optic nerve, combined with third cranial nerve palsy after methanol ingestion.

Long-Lasting Cranial Nerve III Palsy as a Presenting Feature of Chronic Inflammatory Demyelinating Polyneuropathy

Directory of Open Access Journals (Sweden)

Rossella Spataro

2015-01-01

Full Text Available We describe a patient with chronic inflammatory demyelinating polyneuropathy (CIDP in which an adduction deficit and ptosis in the left eye presented several years before the polyneuropathy. A 52-year-old man presented with a 14-year history of unremitting diplopia, adduction deficit, and ptosis in the left eye. At the age of 45 a mild bilateral foot drop and impaired sensation in the four limbs appeared, with these symptoms showing a progressive course. The diagnostic workup included EMG/ENG which demonstrated reduced conduction velocity with bilateral and symmetrical sensory and motor involvement. Cerebrospinal fluid studies revealed a cytoalbuminologic dissociation. A prolonged treatment with corticosteroids allowed a significant improvement of the limb weakness. Diplopia and ptosis remained unchanged. This unusual form of CIDP presented as a long-lasting isolated cranial nerve palsy. A diagnostic workup for CIDP should therefore be performed in those patients in which an isolated and unremitting cranial nerve palsy cannot be explained by common causes.

The aim of this nationwide cohort study was to evaluate whether the occurrence of isolated 3rd, 4th or 6th cranial nerve (CN) palsies is associated with a higher risk of ischemic stroke. This study utilized data from Taiwan Longitudinal Health Insurance Database during 1995-2012. Subjects aged 20 years or older who had isolated CN 3/4/6 palsies diagnosed by a neurologist or ophthalmologist between January 2000 and December 2011 were included. A set of propensity score matched, randomly sampled patients who had never been diagnosed with CN 3/4/6 palsies were extracted to constitute the control group (cases and controls = 1:4). All subjects were followed until death, loss due to follow-up or completion of the study. Cox proportional hazard regression model stratified by matched pairs was used to estimate the hazards ratio (HR) of ischemic stroke. A total of 657 patients with isolated CN 3/4/6 palsies (61.1% male, mean age 54.8 years) were identified. Compared with control group, the patients with isolated CN 3/4/6 palsies exhibited an increased risk of ischemic stroke (CN3: adjusted HR 3.69 (95% CI 2.20-6.19); CN4: 2.71 (95% CI 1.11-6.64); CN6: 2.15 (95% CI 1.31-3.52)). The association between CN 3/4/6 palsies and ischemic stroke was detected in both separate subgroup and sensitivity analyses. The patients with CN 3/4/6 palsies exhibited an increased risk of developing ischemic stroke. Therefore, isolated ocular motor nerves palsies appear to represent an unrecognized risk factor for ischemic stroke, and these require further confirmation and exploration. © 2016 S.

Nerve ultrasound in Charcot-Marie-Tooth (CMT) disease has focused mostly on the upper limbs. We performed an evaluation of a large cohort of CMT patients in which we sonographically characterized nerve abnormalities in different disease types, ages, and nerves. Seventy patients affected by different CMT types and hereditary neuropathy with liability to pressure palsies (HNPP) were evaluated, assessing median, ulnar, fibular, tibial, and sural nerves bilaterally. Data were correlated with age. Nerve dimensions were correlated with CMT type, age, and nerve site. Nerves were larger in demyelinating than in axonal neuropathies. Nerve involvement was symmetric. CMT1 patients had larger nerves than did patients with other CMT types. Patients with HNPP showed enlargement at entrapment sites. Our study confirms the general symmetry of ultrasound nerve patterns in CMT. When compared with ultrasound studies of nerves of the upper limbs, evaluation of the lower limbs did not provide additional information.

Unusually large quiescent ancient schwannoma of hypoglossal nerve

Directory of Open Access Journals (Sweden)

Sangeeta P Wanjari

2013-01-01

Full Text Available Ancient schwannoma is considered as a variant of schwannoma, comprising about 10% of all schwanommas. Schwannoma is a benign neoplasm derived from the nerve sheath of peripheral motor, sensory and sympathetic nerves and from the cranial nerve pairs. It usually presents as a solitary soft-tissue lesion which is slow growing, encapsulated and is often associated with nerve attached peripherally. Diagnosis is often confirmed with the microscopic examination. The long standing schwannoma attributes to degenerative changes and is termed "ancient" schwannoma. Present case is of a 68-year-old female patient who reported with an asymptomatic large swelling below mandible on the left side since last 23 years. The lesion was surgically excised under general anesthesia.

Ptosis as partial oculomotor nerve palsy due to compression by infundibular dilatation of posterior communicating artery, visualized with three-dimensional computer graphics: case report.

Oculomotor nerve palsy (ONP) due to internal carotid-posterior communicating artery (PcomA) aneurysm generally manifests as partial nerve palsy including pupillary dysfunction. In contrast, infundibular dilatation (ID) of the PcomA has no pathogenic significance, and mechanical compression of the cranial nerve is extremely rare. We describe a 60-year-old woman who presented with progressive ptosis due to mechanical compression of the oculomotor nerve by an ID of the PcomA. Three-dimensional computer graphics (3DCG) accurately visualized the mechanical compression by the ID, and her ptosis was improved after clipping of the ID. ID of the PcomA may cause ONP by mechanical compression and is treatable surgically. 3DCG are effective for the diagnosis and preoperative simulation.

2016-03-01

To compare surgical clipping with endovascular coiling in terms of recovery from oculomotor nerve palsy (ONP) in the management of posterior communicating artery (PCoA) aneurysms causing third nerve palsy. We conducted a systematic review of the literature and meta-analysis. The meta-analysis included 11 relevant studies involving 384 patients with third nerve palsy caused by PCoA aneurysms at baseline, of whom 257 (67.0%) were treated by clipping and 127 were treated by coiling (33.0%). Pooled odds ratios of the impact of clipping or coiling on complete ONP recovery, lack of ONP recovery, and procedure-related death were calculated. The overall complete ONP recovery rate was 42.5% in the coiling group compared with 83.6% in the clipping group. The increase in complete ONP recovery in the clipping group corresponds to an overall pooled Mantel-Haenszel odds ratio of 4.44 (95% confidence interval = 1.66-11.84). Subgroup analysis revealed a clear benefit of clipping over coiling in patients with ruptured aneurysms, but not in patients with unruptured aneurysms. No procedure-related deaths were reported by any of the 11 studies. Surgical clipping of PCoA aneurysms causing third nerve palsy achieves better ONP recovery than endovascular coiling; this could be particularly true in the case of ruptured aneurysms. In view of the purely observational data, statements about this effect should be made with great caution. A randomized trial would better address the therapeutic dilemma, but pending the results of such a trial, we recommend treating PCoA aneurysms causing ONP with surgery. Copyright © 2016 Elsevier Inc.

Hsu, Ko-Chiang; Wang, Ann-Ching; Chen, Shyi-Jou

2008-03-01

Delayed-onset facial nerve paralysis is a rather uncommon complication of a mastoid bone fracture for children younger than 10 years. We routinely arrange a cranial computed tomography (CT) for patients encountering initial loss of consciousness, severe headache, intractable vomiting, and/or any neurologic deficit arising from trauma to the head. However, minor symptomatic cranial nerve damage may be missed and the presenting symptom diagnosed as being a peripheral nerve problem. Herein, we report a case of a young boy who presented at our emergency department (ED) 3 days subsequent to his accident, complaining of hearing loss in the right ear and paralysis of the ipsilateral face. Unpredictably, we observed his cranial CT scan revealing a linear fracture of the skull over the right temporal bone involving the right mastoid air cells. The patient was treated conservatively and recovered well without any adverse neurologic consequences. We emphasize that ED physicians should arrange a cranial CT scan for a head-injured child with symptomatic facial nerve palsy, even if there are no symptoms such as severe headache, vomiting, Battle sign, and/or initial loss of consciousness.

Immediate Postoperative Bell's Palsy: Viral Etiology or Post-Traumatic Phenomena?

Directory of Open Access Journals (Sweden)

Mohammad Ghasem Shams

2010-12-01

Full Text Available Introduction: Bell’s palsy is a sudden unilateral paralysis of the facial nerve. Postoperative Bell’s palsy following surgery is rare. It occurs in less than 1% of operations. The hypothesis: We premise that the main cause of immediate postoperative Bell's palsy is latent herpes viruses (herpes simplex virus type 1 and herpes zoster virus, which are reactivated from cranial nerve ganglia. Inflammation of the nerve initially results in a reversible neurapraxia, but ultimately Wallerian degeneration ensues. The palsy is often sudden in onset and evolves rapidly, with maximal facial weakness developing within two days. Associated symptoms of-ten seen in idiopathic Bell’s palsy are tearing problems, hyperacusis and altered taste.Evaluation of the hypothesis: Facial paralysis presenting postoperatively is distressing and poses a diagnostic chal-lenge. A complete interruption of the facial nerve at the sty-lomastoid foramen paralyzes all the muscles of facial expression. Taste sensation may be lost unilaterally and hye-racusis may be present. Idiopathic Bell’s palsy is due to inflammation of the facial nerve in the facial canal. Bell’s palsy may also occur from lesions that invade the temporal bone (carotid body, cholesteatoma, dermoid cyst, acoustic neu-romas. Although traumatic Bell’s palsy cannot be ruled out, it seems logic to postulate that the main cause of immediate postoperative Bell's palsy is latent herpes viruses.

Internal carotid artery (ICA) lesions in the parapharyngeal space (a dissection and a pseudoaneurysm) may present as isolated lower cranial nerves (IX, X, XI, and XII) palsy (Collet-Sicard syndrome). Some arteriopathies such as fibromuscular dysplasia and tortuosity make a vessel predisposed to dissection. Extreme vessel tortuosity makes the treatment by a stent graft impossible. Two Silk stents were used in a 46 year-old man with left lower cranial nerves (IX-XII) palsy for the treatment of left ICA spontaneous dissection with pseudoaneurysm. A follow-up angiogram 5 months later confirmed pseudoaneurysm thrombosis and patency of the left ICA. The patient recovered completely from the deficits.

We performed Gd-DTPA-enhanced magnetic resonance imaging (MRI) examinations at several stages in 40 patients with peripheral facial nerve palsy (Bell's palsy and Ramsay-Hunt syndrome). In 38 of the 40 patients, one and more enhanced region could be seen in certain portion of the facial nerve in the temporal bone on the affected side, whereas no enhanced regions were seen on the intact side. Correlations between the timing of the MRI examination and the location of the enhanced regions were analysed. In all 6 patients examined by MRI within 5 days after the onset of facial nerve palsy, enhanced regions were present in the meatal portion. In 3 of the 8 patients (38%) examined by MRI 6 to 10 days after the onset of facial palsy, enhanced areas were seen in both the meatal and labyrinthine portions. In 8 of the 9 patients (89%) tested 11 to 20 days after the onset of palsy, the vertical portion was enhanced. In the 12 patients examined by MRI 21 to 40 days after the onset of facial nerve palsy, the meatal portion was not enhanced while the labyrinthine portion, the horizontal portion and the vertical portion were enhanced in 5 (42%), 8 (67%) and 11 (92%), respectively. Enhancement in the vertical portion was observed in all 5 patients examined more than 41 days after the onset of facial palsy. These results suggest that the central portion of the facial nerve in the temporal bone tends to be enhanced in the early stage of facial nerve palsy, while the peripheral portion is enhanced in the late stage. These changes of Gd-DTPA enhanced regions in the facial nerve may suggest dromic degeneration of the facial nerve in peripheral facial nerve palsy. (author).

Delayed Onset of Isolated Unilateral Oculomotor Nerve Palsy Caused by Post-Traumatic Pituitary Apoplexy: A Case Report

Tomoki Ishigaki

2017-09-01

Full Text Available Post-traumatic pituitary apoplexy is uncommon, most of which present with a sudden onset of severe headache and visual impairments associated with a dumbbell-shaped pituitary tumor. We experienced an unusual case of post-traumatic pituitary apoplexy with atypical clinical features. A 66-year-old man presented with mild cerebral contusion and an incidentally diagnosed intrasellar tumor after a fall accident with no loss of consciousness. The patients denied any symptoms before the accident. After 4 days, the left oculomotor nerve palsy developed and deteriorated associated with no severe headache. Repeated neuroimages suggested that pituitary apoplexy had occurred at admission and showed that the tumor compressed the left cavernous sinus. The patient underwent endonasal transsphenoidal surgery at 6 days after head injury, and the mass reduction improved the oculomotor nerve palsy completely within the following 14 days. The pathologic diagnosis was nonfunctioning pituitary adenoma with hemorrhage and necrosis.

To describe a case of the rare complication of facial palsy following preoperative embolization of a juvenile nasopharyngeal angiofibroma (JNA). To illustrate the vascular supply to the facial nerve and as a result, highlight the etiology of the facial nerve palsy. The angiography and magnetic resonance (MR) imaging of a case of facial palsy following preoperative embolization of a JNA is reviewed. A 13-year-old male developed left-sided facial palsy following preoperative embolization of a left-sided JNA. Evaluation of MR imaging studies and retrospective review of the angiographic data suggested errant embolization of particles into the petrosquamosal branch of the middle meningeal artery (MMA), a branch of the internal maxillary artery (IMA), through collateral vasculature. The petrosquamosal branch of the MMA is the predominant blood supply to the facial nerve in the facial canal. The facial palsy resolved since complete infarction of the nerve was likely prevented by collateral blood supply from the stylomastoid artery. Facial palsy is a potential complication of embolization of the IMA, a branch of the external carotid artery (ECA). This is secondary to ischemia of the facial nerve due to embolization of its vascular supply. Clinicians should be aware of this potential complication and counsel patients accordingly prior to embolization for JNA.

Preoperative percutaneous cranial nerve mapping in head and neck surgery.

Park, Jung I

To identify and map the course of the peripheral branches of the cranial nerve preoperatively and percutaneously. Prospective study. Preoperative percutaneous nerve mapping performed prior to the operation under deep sedation or general anesthesia without muscle paralysis. Private office surgery suite, freestanding surgery center, and regional medical centers. A total of 142 patients undergoing head and neck surgery and facial plastic surgery between August 1994 and July 1999. Monopolar probe was used for nerve stimulation. Electromyographic reading was done through intramuscular bipolar recording electrodes. The equipment used was a nerve monitor. The mandibular divisions were tested in 142 cases, the frontal division in 60 cases, the accessory nerve in 12 cases, and the hypoglossal nerve in 3 cases. Satisfactory mappings were obtained in 115 cases of the mandibular division, 49 cases of the frontal division, 8 cases of the accessory division, and 1 case of the hypoglossal nerve. Preoperative percutaneous nerve mapping is a new method of identifying the location of the peripheral branches of the cranial nerves. Identifying and mapping the course of peripheral branches of the cranial nerves safely assists the head and neck surgeon in the placement of incisions in a favorable location and in the dissection of the area involving the nerves. Mapping alerts the surgeon to an area containing a nerve and allows the surgeon to avoid just the specific area where a nerve is present, preventing large-scale abandonment of unmapped areas for fear of potential nerve damage.

The impact of intraoperative neuromonitoring on recurrent laryngeal nerve palsy remains debated. Our aim was to evaluate the potential protective effect of intraoperative neuromonitoring on recurrent laryngeal nerve during total thyroidectomy. This was a prospective, multicenter French national study. The use of intraoperative neuromonitoring was left at the surgeons' choice. Postoperative laryngoscopy was performed systematically at day 1 to 2 after operation and at 6 months in case of postoperative recurrent laryngeal nerve palsy. Univariate and multivariate analyses and propensity score (sensitivity analysis) were performed to compare recurrent laryngeal nerve palsy rates between patients operated with or without intraoperative neuromonitoring. Among 1,328 patients included (females 79.9%, median age 51.2 years, median body mass index 25.6 kg/m 2 ), 807 (60.8%) underwent intraoperative neuromonitoring. Postoperative abnormal vocal cord mobility was diagnosed in 131 patients (9.92%), including 69 (8.6%) and 62 (12.1%) in the intraoperative neuromonitoring and nonintraoperative neuromonitoring groups, respectively. Intraoperative neuromonitoring was associated with a lesser rate of recurrent laryngeal nerve palsy in univariate analysis (odds ratio = 0.68, 95% confidence interval, 0.47; 0.98, P = .04) but not in multivariate analysis (oddsratio = 0.74, 95% confidence interval, 0.47; 1.17, P = .19), or when using a propensity score (odds ratio = 0.76, 95% confidence interval, 0.53; 1.07, P = .11). There was no difference in the rates of definitive recurrent laryngeal nerve palsy (0.8% and 1.3% in intraoperative neuromonitoring and non-intraoperative neuromonitoring groups respectively, P = .39). The sensitivity, specificity, and positive and negative predictive values of intraoperative neuromonitoring for detecting abnormal postoperative vocal cord mobility were 29%, 98%, 61%, and 94%, respectively.

Conclusion: Contrary to our expectations, secondary procedures and prior multiple surgeries with failed implants and poor soft tissue were not predictive factors of postoperative deficit. From our study, we also conclude that radial nerve recovery can be reasonably expected in all patients with a postoperative palsy following the anterolateral approach.

Common Peroneal Nerve Palsy with Multiple-Ligament Knee Injury and Distal Avulsion of the Biceps Femoris Tendon

Directory of Open Access Journals (Sweden)

2015-01-01

Full Text Available A multiple-ligament knee injury that includes posterolateral corner (PLC disruption often causes palsy of the common peroneal nerve (CPN, which occurs in 44% of cases with PLC injury and biceps femoris tendon rupture or avulsion of the fibular head. Approximately half of these cases do not show functional recovery. This case report aims to present a criteria-based approach to the operation and postoperative management of CPN palsy that resulted from a multiple-ligament knee injury in a 22-year-old man that occurred during judo. We performed a two-staged surgery. The first stage was to repair the injuries to the PLC and biceps femoris. The second stage involved anterior cruciate ligament reconstruction. The outcomes were excellent, with a stable knee, excellent range of motion, and improvement in the palsy. The patient was able to return to judo competition 27 weeks after the injury. To the best of our knowledge, this is the first case report describing a return to sports following CPN palsy with multiple-ligament knee injury.

Bell's palsy is defined as a peripheral facial nerve palsy, idiophatic, and sudden onset and is considered the most common cause of this pathology. It is caused by damage to cranial nerves VII, resulting in complete or partial paralysis of the facial mimic. May be associated with taste disturbances, salivation, tearing and hyperacusis. It is diagnosed after ruling out all possible etiologies, because its cause is not fully understood.Some researches shows that herpes virus may cause this type of palsy due to reactivation of the virus or by imunnomediated post-viral nerve demielinization. Physical therapy, corticosteroids and antiviral therapy have become the most widely accepted treatments for Bell's palsy. Therapy with low-level laser (LLLT) may induce the metabolism of injured nerve tissue for the production of proteins associated with its growth and to improve nerve regeneration. The success of the treatment of Bell's palsy by using laser phototherapy isolated or in association with other therapeutic approach has been reported on the literature. In most cases, the recovery occurs without uneventfully (complications), the acute illness is not associated with serious disorders. We will present a clinical approach for treating this condition.

Bell's palsy, named after the Scottish anatomist, Sir Charles Bell, is the most common acute mono-neuropathy, or disorder affecting a single nerve, and is the most common diagnosis associated with facial nerve weakness/paralysis. Bell's palsy is a rapid unilateral facial nerve paresis (weakness) or paralysis (complete loss of movement) of unknown cause. The condition leads to the partial or complete inability to voluntarily move facial muscles on the affected side of the face. Although typically self-limited, the facial paresis/paralysis that occurs in Bell's palsy may cause significant temporary oral incompetence and an inability to close the eyelid, leading to potential eye injury. Additional long-term poor outcomes do occur and can be devastating to the patient. Treatments are generally designed to improve facial function and facilitate recovery. There are myriad treatment options for Bell's palsy, and some controversy exists regarding the effectiveness of several of these options, and there are consequent variations in care. In addition, numerous diagnostic tests available are used in the evaluation of patients with Bell's palsy. Many of these tests are of questionable benefit in Bell's palsy. Furthermore, while patients with Bell's palsy enter the health care system with facial paresis/paralysis as a primary complaint, not all patients with facial paresis/paralysis have Bell's palsy. It is a concern that patients with alternative underlying etiologies may be misdiagnosed or have unnecessary delay in diagnosis. All of these quality concerns provide an important opportunity for improvement in the diagnosis and management of patients with Bell's palsy. The primary purpose of this guideline is to improve the accuracy of diagnosis for Bell's palsy, to improve the quality of care and outcomes for patients with Bell's palsy, and to decrease harmful variations in the evaluation and management of Bell's palsy. This guideline addresses these needs by encouraging

Summary Endovascular packing of intracranial aneurysm with preservation of the parent vessel has become in many cases a valid alternative to surgical clipping. Regression of oculomotor disorders after clipping of internal carotid-posterior communicating artery (ICA-PCoA) aneurysms has been well assessed. This report focuses on the reversal of third nerve palsy after endovascular packing of ICA-PCoA aneurysms. To this end, clinical appearances, neuroradiological features, and endovascular interventional procedures of six treated patient are reported and discussed in the light of the very few previous case observations found in the literature. Results indicate that endovascular packing of ICA-PCoA aneurysms may produce effective recovery of correlated third nerve dysfunction. PMID:20667199

Peroneal nerve palsy is a frequent and potentially disabling complication of multiligament knee dislocation, but little information exists on the degree to which patients recover motor or sensory function after this injury, and whether having this nerve injury--with or without complete recovery--is a predictor of inferior patient-reported outcome scores. The purposes of this study were to (1) report on motor and sensory recovery as well as patient-reported outcomes scores of patients with peroneal nerve injury from multiligament knee dislocation; (2) compare those endpoints between patients who had partial versus complete nerve injuries; and (3) compare patient-reported outcomes among patients who sustained peroneal nerve injuries after knee dislocation with a matched cohort of multiligament knee injuries without nerve injury. Thirty-two patients were identified, but five did not have 2-year followup and are excluded (16% lost to followup). Twenty-seven patients (24 male, three female) with peroneal nerve injury underwent multiligament knee reconstruction and were followed for 6.3 years (range, 2-18 years). Motor grades were assessed by examination and outcomes by International Knee Documentation Committee (IKDC) and Lysholm scores. Retrospectively, patients were divided into complete (n = 9) and partial nerve palsy (n = 18). Treatment for complete nerve palsy included an ankle-foot orthosis for all patients, nonoperative (one), neurolysis (two), tendon transfer (three), nerve transfer (one), and combined nerve/tendon transfer (one). Treatment for partial nerve palsy included nonoperative (12), neurolysis (four), nerve transfer (one), and combined nerve/tendon transfer (one). Furthermore, patients without nerve injury were matched by Schenck classification, age, and sex. Data were analyzed using univariate and multivariate models. Overall, 18 patients (69%) regained antigravity ankle dorsiflexion after treatment (three complete nerve palsy [38%] versus 15 partial

The effects of aging on hypoglossal motoneurons in rats.

Aging can result in a loss of neuronal cell bodies and a decrease in neuronal size in some regions of the brain and spinal cord. Motoneuron loss in the spinal cord is thought to contribute to the progressive decline in muscle mass and strength that occurs with age (sarcopenia). Swallowing disorders represent a large clinical problem in elderly persons; however, age-related alterations in cranial motoneurons that innervate muscles involved in swallowing have been understudied. We aimed to determine if age-related alterations occurred in the hypoglossal nucleus in the brainstem. If present, these changes might help explain alterations at the neuromuscular junction and changes in the contractile properties of tongue muscle that have been reported in older rats. We hypothesized that with increasing age there would be a loss of motoneurons and a reduction in neuronal size and the number of primary dendrites associated with each hypoglossal motoneuron. Neurons in the hypoglossal nucleus were visualized with the neuronal marker NeuN in young (9-10 months), middle-aged (24-25 months), and old (32-33 months) male F344/BN rats. Hypoglossal motoneurons were retrograde-labeled with injections of Cholera Toxin beta into the genioglossus muscle of the tongue and visualized using immunocytochemistry. Results indicated that the number of primary dendrites of hypoglossal motoneurons decreased significantly with age, while no age-associated changes were found in the number or size of hypoglossal motoneurons. Loss of primary dendrites could reduce the number of synaptic inputs and thereby impair function.

Facial nerve is easy to be damaged, and there are many reconstructive methods for facial nerve reconstructive, such as facial nerve end to end anastomosis, the great auricular nerve graft, the sural nerve graft, or hypoglossal-facial nerve anastomosis. However, there is still little study about great auricular-facial nerve neurorrhaphy. The aim of the present study was to identify the role of great auricular-facial nerve neurorrhaphy and the mechanism. Rat models of facial nerve cut (FC), facial nerve end to end anastomosis (FF), facial-great auricular neurorrhaphy (FG), and control (Ctrl) were established. Apex nasi amesiality observation, electrophysiology and immunofluorescence assays were employed to investigate the function and mechanism. In apex nasi amesiality observation, it was found apex nasi amesiality of FG group was partly recovered. Additionally, electrophysiology and immunofluorescence assays revealed that facial-great auricular neurorrhaphy could transfer nerve impulse and express AChR which was better than facial nerve cut and worse than facial nerve end to end anastomosis. The present study indicated that great auricular-facial nerve neurorrhaphy is a substantial solution for facial lesion repair, as it is efficiently preventing facial muscles atrophy by generating neurotransmitter like ACh.

, independent of the treatment regimen. In the Bell's paralysis group, 38 patients (70%) recovered completely after 1 year, including 94% of patients with a denervation by ENoG of less than 90%. Thirty percent of Bell's paralysis patients recovered incompletely, revealing the worst outcome in patients with a 100% denervation on ENoG. None of the 4 patients with HZO and ENoG denervation of more than 90% recovered to normal facial function. We found a highly significant difference regarding the time course and final outcome in patients with incomplete palsies versus total paralysis; however, only 3 of 250 studies make this distinction. The time course for improvement and the extent of recovery is significantly different in patients presenting with an incomplete facial nerve paresis compared with patients with a total paralysis. Whereas the term "palsy" includes both entities, the term "paralysis" should only be used to describe total loss of nerve function. Patients with incomplete acute Bell's palsy (paresis) should start to improve their facial function early (1-2 wk after onset) and are expected to recover completely within 3 months. These patients do not benefit from antiviral medications and most likely do not profit from systemic steroids. Mixing patients with different severity of palsies will always lead to controversial results.

Full Text Available Thrombosis of the cerebral veins and sinuses is an infrequent cerebrovascular disorder. Because the highly variable symptoms, recent neuroimaging plays a key role in the diagnosis. Abducens nerve palsy as a focal neurological deficit is a rare clinical manifestation in these patients. We present two cases with sudden onset of diplopia and headache. Case 1: A 3-year old girl with B cell lymphoblastic leukemia developed bilateral abducens deficit and bilateral optic disc edema after treatment including L-asparaginase. Thrombosis of the right jugular vein, sagittal and right sigmoid sinuses was visualized on magnetic resonance imaging (MRI and magnetic resonance venography (MRV. Symptoms gradually resolved after treatment with enoxiparine and MRV demonstrated recanalization.Case 2: A 75-year old female with medical history of arterial hypertension presented with headache and sudden left abduction deficit. Computerized tomography (CT scan was normal. MRI and MRV revealed aging brain and disruption of venous flow at the left internal jugular vein, suspecting thrombosis. Extracranial colour duplex sonography and CT angiography proved haemodinamic equivalent of left internal jugular vein thrombosis due to sclerotic pathology of aortic arch.Our first case illustrates the role of improved neuroimaging techniques as the best method for diagnosis of cerebral veins and sinuses thrombosis, presenting with abducens nerve palsy. With second case the potential neuroimaging pitfalls concerning the accurate diagnosis of these cerebrovascular disorders with neuro-ophthalmologic manifestation are discussed.

Granulomatosis with polyangiitis (GPA, previously known as Wegener's granulomatosis) is an autoimmune systemic small-vessel vasculitis, associated with the presence of anti-neurophil cytoplasmic antibodies with a cytoplasmic staining pattern (c-ANCA). It is characterized by necrotizing granulomas, usually affecting the airways and kidneys. GPA should be considered when patients do not improve despite adequate treatment of otologic symptoms, when patients have unspecific symptoms suggesting systemic disease (e.g. fever, malaise), or when other organs are involved (kidney, lungs, etc.). We present an interesting case of a 14-year-old female with eight-weeks of bilateral otalgia, unilateral facial nerve palsy, decreased appetite, and fatigue refractory to steroid, anti-viral, and antibiotic treatment ultimately diagnosed with GPA.

Purpose: To evaluate various prognostic factors and the impact of imaging modalities on tumor control in patients with nasopharyngeal cancer (NPC) with cranial nerve (China) palsy. Material and Methods: Between September 1979 and December 2000, 330 NPC patients with CN palsy received radical radiotherapy (RT) by the conventional opposing technique at Chang Gung Memorial Hospital-Linkou. Imaging methods used varied over that period, and included conventional tomography (Tm) for 47 patients, computerized tomography (CT) for 195 patients, and magnetic resonance image (MRI) for 88 patients. Upper CN (II-VI) palsy was found in 268 patients, lower CN (IX-XII) in 13, and 49 patients had both. The most commonly involved CN were V or VI or both (23%, 12%, and 16%, respectively). All patients had good performance status (World Health Organization <2). The median external RT dose was 70.2 Gy (range, 63-77.5 Gy). Brachytherapy was also given to 156 patients in addition to external RT, delivered by the remote after-loading, high-dose-rate technique. A total of 139 patients received cisplatin-based chemotherapy, in 115 received as neoadjuvant or adjuvant chemotherapy and in 24 concomitant with RT. Recovery from CN palsy occurred in 171 patients during or after radiotherapy. Patients who died without a specific cause identified were regarded as having died with persistent disease. Results: The 3-year, 5-year, and 10-year overall survival was 47.1%, 34.4%, and 22.2%. The 3-year, 5-year, and 10-year disease-specific survival (DSS) rates were 50.4%, 37.8%, and 25.9%. The 5-year DSS for patients staged with MRI, CT, and Tm were 46.9%, 36.7%, and 21.9%, respectively (p = 0.016). The difference between MRI and CT was significant (p = 0.015). The 3-year and 5-year local control rates were 62% and 53%, respectively. The 5-year local control was 68.2% if excluding patients who died without a specific cause. Patients who had an MRI had a significantly better tumor control rate than those

Multidetector computerized tomography (MDCT) with improved temporal and spatial resolution is one of the most commonly used non-invasive tests for evaluation of pulmonary veins (PVs) and adjacent structures before cryoablation of atrial fibrillation (AF). Identification of spatial neighbouring of phrenic nerves is important to decrease likelihood of phrenic nerve palsy (PNP). The purpose of our study is to clarify the course of right phrenic nerve, its relations to PVs using 64-slice MDCT, and effect on occurrence of PNP. A total of 162 patients underwent MDCT with 3D reconstruction of left atrium prior to cryoablation for AF. The location of the right pericardiophrenic artery (RPA) was identified on axial images and artery distance to the right upper PV (RUPV) ostium was measured in 3D image. Right pericardiophrenic artery was detectable in 145 of 162 (89.5%) patients (52.4% male, age 54.5 ± 10.1 years, and 80.7% paroxysmal AF). Acute procedural success rate was 96.2%. Mean procedural and fluoroscopy times were 74.4 ± 6.2 and 15.7 ± 4.3 min. Transient right PNP was developed in four (2.75%) patients. RUPV ostium to RPA distance was lower in patients with PNP (P = 0.033). In multivariate regression analysis, only RUPV ostium to RPA distance (odds ratio: 2.95; 95% confidence interval: 1.76-4.66, P = 0.001) was the independent predictor of PNP occurrence during cryoablation. Our results revealed that pre-ablation cardiac imaging with 64-slice MDCT adequately detected RPA bordering the phrenic nerve, which was an important determinant of PNP development during cryoballoon-based AF ablation.

Full Text Available In the article we present the results of the retrospective clinico-electrophysiological analysis of 182 patients suffering from the idiopathic neuropathy of the facial nerve (Bell`s palsy. The comparison of the most common electromyographical (ENMG predictors of outcomes was made. It was demonstrated that the most sensitive method in the acutest period (less then 5 days is the level of excitability of the nerve, in the acute period (less then 14 days – estimation of M-answer amplitude loss, and from the 21st day – the presence of denervation in muscles. The most specific electromyographical approach to estimate the therapy efficiency is an analysis of the M-answer amplitude and latency. In conclusion, neurologists have the possibility to predict the outcome and to control the therapy efficiency in any period of the disease. The correlation dynamics ÈNMG sensitivity settings – NLN on different dates can be used to determine the volume of ÈNMG – the NLN study depending on the timing for the treatment of patients.

Diagnostic gait pattern of a patient with longstanding left femoral nerve palsy: a case report.

LENUS (Irish Health Repository)

Burke, Neil G

2010-12-01

The gait pattern of a 35-year-old man with longstanding, left femoral nerve palsy was assessed using 3-dimensional kinematic and kinetic analysis. Stability of his left knee in stance was achieved by manipulating the external moments of the limb so that the ground reaction force passes in front of the knee joint. This compensatory mechanism of locking the knee in extension is reliant on the posterior capsular structures. The patient was managed conservatively and continued to walk without aids.

Gd-DTPA-enhanced MR imaging in facial nerve paralysis

Tien, R.D.; Dillon, W.P.

1989-01-01

GD-DTPA-enhanced MR imaging was used to evaluate 11 patients with facial nerve paralysis (five acute idiopathic facial palsy (Bell palsy), three chronic recurrent facial palsy, one acute facial palsy after local radiation therapy, one chronic facial dyskinesia, and one facial neuroma). In eight of 11 patients, there was marked enhancement of the infratemporal facial nerve from the labyrinthine segment to the stylomastoid foramen. Two patients had additional contrast enhancement in the internal auditory canal segment. In one patient, enhancement persisted (but to a lesser degree) 8 weeks after symptoms had resolved. In one patient, no enhancement was seen 15 months after resolution of Bell palsy. The facial neuroma was seen as a focal nodular enhancement in the mastoid segment of the facial nerve

The phrenic nerve can be transferred to the musculocutaneous nerve in patients with traumatic brachial plexus palsy in order to recover biceps strength, but the results are controversial. There is also a concern about pulmonary function after phrenic nerve transection. In this paper, we performed a qualitative systematic review, evaluating outcomes after this procedure. A systematic review of published studies was undertaken in accordance with the Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) statement. Data were extracted from the selected papers and related to: publication, study design, outcome (biceps strength in accordance with BMRC and pulmonary function) and population. Study quality was assessed using the "strengthening the reporting of observational studies in epidemiology" (STROBE) standard or the CONSORT checklist, depending on the study design. Seven studies were selected for this systematic review after applying inclusion and exclusion criteria. One hundred twenty-four patients completed follow-up, and most of them were graded M3 or M4 (70.1 %) for biceps strength at the final evaluation. Pulmonary function was analyzed in five studies. It was not possible to perform a statistical comparison between studies because the authors used different parameters for evaluation. Most of the patients exhibited a decrease in pulmonary function tests immediately after surgery, with recovery in the following months. Study quality was determined using STROBE in six articles, and the global score varied from 8 to 21. Phrenic nerve transfer to the musculocutaneous nerve can recover biceps strength ≥M3 (BMRC) in most patients with traumatic brachial plexus injury. Early postoperative findings revealed that the development of pulmonary symptoms is rare, but it cannot be concluded that the procedure is safe because there is no study evaluating pulmonary function in old age.

A 64-year-old woman with Lyme disease and manifesting facial nerve palsy had been bitten by a tick on the left frontal scalp 4 weeks previously. Erythema migrans appeared on the left forehead, accompanied by left facial paralysis. Nested polymerase chain reaction-restriction fragment length polymorphism analysis (nested PCR-RFLP) was performed on DNA extracted from a skin biopsy of the erythema on the left forehead. Borrelia flagellin gene DNA was detected and its RFLP pattern indicated that the organism was B. garinii, Five weeks later, B. garinii was isolated by conventional culture from the erythematous skin lesion, but not from the cerebrospinal fluid. After treatment with ceftriaxone intravenously for 10 days and oral administration of minocycline for 7 days, both the erythema and facial nerve palsy improved significantly. Nested PCR and culture taken after the lesion subsided, using skin samples obtained from a site adjacent to the original biopsy, were both negative. We suggest that nested PCR-RFLP analysis might be useful for the rapid diagnosis of Lyme disease and for evaluating therapy.

Background  C7 - T1 palsy results in complete loss of finger motion and poses a surgical challenge. This study investigated the anatomy of the radial nerve in the elbow and forearm and the feasibility of intraplexus nerve transfer to restore thumb and finger extension. Methods  The radial nerves were dissected in 28 formalin-fixed upper extremities. Branching pattern, length, diameter, and number of myelinated fibers were recorded. Results  Commonly, the branching pattern (from proximal to distal) was to the brachioradialis, extensor carpi radialis longus, superficial sensory proximal to the lateral epicondyle, extensor carpi radialis brevis, supinator, extensor digitorum communis, extensor digiti minimi, extensor carpi ulnaris, abductor pollicis longus, extensor pollicis brevis, extensor pollicis longus, and extensor indicis distal to the lateral epicondyle. Conclusions  Branches to the brachioradialis, extensor carpi radialis longus, and supinator can be transferred to the posterior interosseous nerve to restore hand movement in patients with C7 - T1 brachial plexus palsies; the supinator branch is probably the best choice in this regard.

Bachtiar, Arian; Auer, Herbert; Finsterer, Josef

2012-10-01

Toxocarosis involving cranial nerves is extremely rare and almost exclusively concerns the optic nerve. Toxocarosis involving the seventh cranial nerve has not been reported. A 33y male developed left-sided Bell's palsy two days after left-sided otalgia 6y before. Despite extensive diagnostic work-up at that time the cause of Bell's palsy remained unknown. During the following years Bell's palsy slightly improved but retromandibular pain remained almost unchanged and he developed enlarged lymph nodes along the jugular veins, submandibularly, and in the trigonum caroticum. Re-evaluation 6y later revealed an increased titer of serum antibodies against Toxocara canis and a positive Westernblot for Toxocara canis ES-antigen. Despite absent eosinophilia in the serum, toxocarosis was diagnosed and a therapy with albendazole initiated, with benefit for retromandibular pain, but hardly for Bell's palsy or enlarged lymph nodes. CSF investigations after albendazole revealed a positive Westernblot for antibodies against toxocara but absent pleocytosis or eosinophilia, and negative PCR for Toxocara canis. Visceral larva migrans due to Toxocara canis may be associated with Bell's palsy, retromandibular pain, and lymphadenopathy. A causal relation between Bell's palsy and the helminthosis remains speculative. Adequate therapy years after onset of the infestation may be of limited benefit.

Bell's palsy is a condition that affects the facial nerve, which is one of the twelve cranial nerves. Its main function is to control all the muscles of the facial expression. It is a unilateral, acute, partial or complete paralysis of the facial nerve. Bell's palsy remains the most common cause of facial nerve paralysis, more often encountered in females aged 17 to 30 years, recurrent in many cases and with poor associations with other pathologic conditions. In modern literature, the suspected etiology could be due to the reactivation of the latent herpes viral infections in the geniculate ganglia, and their subsequent migration to the facial nerve but, favorable outcome by using vasodilators, neurotrophic and corticosteroid therapy was recorded.

Idiopathic facial nerve palsy, also known as Bell palsy is rare in the neonatal age group. Other more common causes such as birth trauma; infections, especially otitis media; and congenital malformations need to be excluded. We present here a 4-week-old neonate with Bell palsy who responded rapidly to oral corticosteroids. Such an early presentation of idiopathic facial nerve palsy and use of corticosteroids in neonates is scarcely reported in the literature.

Aberrant regeneration of the third cranial nerve is most commonly due to its damage by trauma. A ten-month old child presented with the history of a fall from a four-storey building. She developed traumatic third nerve palsy and eventually the clinical features of aberrant regeneration of the third cranial nerve. The adduction of the eye improved over time. She was advised for patching for the strabismic amblyopia as well. Traumatic third nerve palsy may result in aberrant regeneration of the third cranial nerve. In younger patients, motility of the eye in different gazes may improve over time. © NEPjOPH.

The lower cranial nerves receive their arterial supply from an intricate network of tributaries derived from the external carotid, internal carotid, and vertebrobasilar territories. A contemporary, comprehensive literature review of the vascular supply of the lower cranial nerves was performed. The vascular supply to the trigeminal, facial, vestibulocochlear, glossopharyngeal, vagus, spinal accessory, and hypoglossal nerves are illustrated with a special emphasis on clinical issues. Frequently the external carotid, internal carotid, and vertebrobasilar territories all contribute to the vascular supply of an individual cranial nerve along its course. Understanding of the vasculature of the lower cranial nerves is of great relevance for skull base surgery. Copyright © 2013 Wiley Periodicals, Inc.

An analysis of facial nerve function in irradiated and unirradiated facial nerve grafts

International Nuclear Information System (INIS)

Brown, Paul D.; Eshleman, Jeffrey S.; Foote, Robert L.; Strome, Scott E.

2000-01-01

Purpose: The effect of high-dose radiation therapy on facial nerve grafts is controversial. Some authors believe radiotherapy is so detrimental to the outcome of facial nerve graft function that dynamic or static slings should be performed instead of facial nerve grafts in all patients who are to receive postoperative radiation therapy. Unfortunately, the facial function achieved with dynamic and static slings is almost always inferior to that after facial nerve grafts. In this retrospective study, we compared facial nerve function in irradiated and unirradiated nerve grafts. Methods and Materials: The medical records of 818 patients with neoplasms involving the parotid gland who received treatment between 1974 and 1997 were reviewed, of whom 66 underwent facial nerve grafting. Fourteen patients who died or had a recurrence less than a year after their facial nerve graft were excluded. The median follow-up for the remaining 52 patients was 10.6 years. Cable nerve grafts were performed in 50 patients and direct anastomoses of the facial nerve in two. Facial nerve function was scored by means of the House-Brackmann (H-B) facial grading system. Twenty-eight of the 52 patients received postoperative radiotherapy. The median time from nerve grafting to start of radiotherapy was 5.1 weeks. The median and mean doses of radiation were 6000 and 6033 cGy, respectively, for the irradiated grafts. One patient received preoperative radiotherapy to a total dose of 5000 cGy in 25 fractions and underwent surgery 1 month after the completion of radiotherapy. This patient was placed, by convention, in the irradiated facial nerve graft cohort. Results: Potential prognostic factors for facial nerve function such as age, gender, extent of surgery at the time of nerve grafting, preoperative facial nerve palsy, duration of preoperative palsy if present, or number of previous operations in the parotid bed were relatively well balanced between irradiated and unirradiated patients.

Spinal accessory nerve schwannomas masquerading as a fourth ventricular lesion

Directory of Open Access Journals (Sweden)

Shyam Sundar Krishnan

2015-01-01

Full Text Available Schwannomas are benign lesions that arise from the nerve sheath of cranial nerves. The most common schwannomas arise from the 8 th cranial nerve (the vestibulo-cochlear nerve followed by trigeminal and facial nerves and then from glossopharyngeal, vagus, and spinal accessory nerves. Schwannomas involving the oculomotor, trochlear, abducens and hypoglossal nerves are very rare. We report a very unusual spinal accessory nerve schwannoma which occupied the fourth ventricle and extended inferiorly to the upper cervical canal. The radiological features have been detailed. The diagnostic dilemma was due to its midline posterior location mimicking a fourth ventricular lesion like medulloblastoma and ependymoma. Total excision is the ideal treatment for these tumors. A brief review of literature with tabulations of the variants has been listed.

Pituitary apoplexy in patients with pituitary macroadenomas can occur either spontaneously or following various interventions. We present a case of a 71-year-old woman who developed third, fourth, and sixth cranial nerve palsies following administration of the four hypothalamic releasing hormones for routine preoperative testing of pituitary function. The MR examination showed interval tumor growth with impression of the floor of the third ventricle. There were also changes in signal intensity characteristics of the mass, suggestive of intratumoral bleeding. A transsphenoidal surgery with subtotal resection of the pituitary adenoma was performed. Microscopical examination revealed large areas of necrosis and blood surrounded by adenomatous tissue. Third, fourth, and sixth cranial nerve palsies completely resolved within 4 months. We conclude that MR imaging is useful in the demonstration of pituitary apoplexy following preoperative stimulation tests, but we suggest that these tests should be abandoned in patients with pituitary macroadenomas

Lower cranial and phrenic nerve involvement is exceptional in hereditary neuropathy with liability to pressure palsies (HNPP). Here we report the occurrence of reversible laryngeal and phrenic nerve involvement in a patient with HNPP. The patient recalled several episodes of reversible weakness and numbness of his feet and hands since the age of 30 years. His medical history was uneventful, apart from chronic obstructive pulmonary disease (COPD). At age 44, following severe weight loss, he presented with progressive dysphonia and hoarseness. EMG of cricoarytenoid and thyroarytenoid muscles and laryngeal fibroscopy confirmed vocal cord paralysis. These speech disturbances gradually regressed. Two years later, he reported rapidly worsening dyspnea. Electroneurography showed increased distal latency of the right phrenic nerve and diaphragm ultrasonography documented reduced right hemi-diaphragm excursion. Six months later and after optimization of CODP treatment, his respiratory function had improved and both phrenic nerve conduction and diaphragm excursion were completely restored. We hypothesize that chronic cough and nerve stretching in the context of CODP, together with severe weight loss, may have triggered the nerve paralysis in this patient. Our report highlights the need for optimal management of comorbidities such as CODP as well as careful control of weight in HNPP patients to avoid potentially harmful complications.

Bell's Palsy is a peripheral facial nerve weakness (facial nerve) with acute onset on one side of the face. This condition causes the inability of the patient to move half of his face consciously (volunter) on the affected side. The Bell's Palsy incidence is 20-30 cases out of 100.000 people and accounts for 60-70% of all cases of unilateral facial paralysis.

This single center retrospective study reviews the management and outcomes of 117 consecutive patients with humeral shaft fractures and associated radial nerve palsy (RNP) treated over a 20-year period (1986-2006). A total of 101 fractures were managed conservatively and 16 fractures underwent external fixation for poor bony alignment. Sixteen grade 1 and 2 open fractures underwent wound toileting alone. No patients underwent initial radial nerve exploration or opening of the fracture sites. All patients achieved clinical and radiological bony union at a mean of 8 weeks (range 7-12 weeks). There were no complications or pin tract infections in the operated patients. A total of 111 cases had initial spontaneous RNP recovery at a mean of 6 weeks (range 3-24 weeks) with full RNP recovery at a mean of 17 weeks (range 3-70 weeks) post-injury. Fourteen patients had no clinical/EMG signs of nerve activity at 12 weeks and 6 subsequently failed to regain any radial nerve recovery; 2 had late explorations and the lacerated nerves underwent sural nerve cable neurorraphy; and 4 patients underwent delayed tendon transposition 2-3 years after initial injury, with good/excellent functional outcomes. Humeral fractures with associated RNP may be treated expectantly. With low rates of humeral nonunion, 95% spontaneous nerve recovery in closed fractures and 94% in grade 1 and 2 open fractures, one has the opportunity of waiting. If at 10-12 weeks there are no clinical/EMG signs of recovery, then nerve exploration/secondary reconstruction is indicated. Late tendon transfers may also give good/excellent functional results.

An unusual presentation of adenoid cystic carcinoma of the minor salivary glands with cranial nerve palsy: a case study

Adenoid Cystic Carcinoma (ACC) is a rare tumor entity and comprises about 1% of all malignant tumor of the oral and maxillofacial region. It is slow growing but a highly invasive cancer with a high recurrence rate. Intracranial ACC is even more infrequent and could be primary or secondary occurring either by direct invasion, hematogenous spread, or perineural spread. We report the first case of the 5 th and 6 th nerve palsy due to cavernous sinus invasion by adenoid cystic carcinoma. A 49-year-old African American female presented to the emergency room complaining of severe right-sided headache, photophobia, dizziness and nausea, with diplopia. The patient had a 14 year history migraine headaches, hypertension, and mild intermittent asthma. Physical examination revealed right lateral rectus muscle palsy with esotropia. There was numbness in all three divisions of the right trigeminal nerve. Motor and sensory examination of extremities was normal. An MRI of the brain/brain stem was obtained which showed a large mass in the clivus extending to involve the nasopharynx, pterygoid plate, sphenoid and right cavernous sinuses. Biopsy showed an ACC tumor with a cribriform pattern of the minor salivary glands. The patient underwent total gross surgical resection and radiation therapy. This is a case of ACC of the minor salivary glands with intracranial invasion. The patient had long history of headaches which changed in character during the past year, and symptoms of acute 5 th and 6 th cranial nerve involvement. Our unique case demonstrates direct invasion of cavernous sinus and could explain the 5 th and 6 th cranial nerve involvement as histopathology revealed no perineural invasion

Full Text Available "nDuring last decades many researchers have focused on the conditions associated with Bell's palsy including diabetes mellitus, hypertension, and viral infections. This study was performed to evaluate correlation of diabetes mellitus and Bell's palsy and some relevant features not discussed in the literature in an Iranian population. The presence of diabetes mellitus was evaluated in a total number of 275 subjects (75 patients with Bell's palsy and 200 control subjects. Diabetes mellitus was noted in 10 (13.3% patients with Bell's palsy among which 6 case were diagnosed as new cases of diabetes. Previous history of Bell's palsy was present in 10.67% of the subjects with Bell's palsy. Symptoms of other cranial nerves revealed higher figures in Bell's palsy patients with underlying diabetes. Such studies in developing countries may reveal some unknown features of the disease. This study confirms the correlation of diabetes mellitus and Bell's palsy for the first time in an Iranian population. The results also suggest that diabetic patients with Bell's palsy suffer from more cranial nerve symptoms. We offer screening tests of diabetes as a routine process in the management of Bell's palsy especially in developing countries.

The Bell's Palsy incidence is 20-30 cases out of 100.000 people and accounts for 60-70% of all cases of unilateral facial paralysis. The disease is self-limited, but causes great suffering for patients who are not treated properly. Controversy in the management is still debated, and the cause is still unknown. The underlying hypothesis is ischemic, vascular, viral, bacterial, hereditary, and immunologic. Therapy done so far is to improve facial nerve function and healing process. The management of the therapy used will be closely related to the structure of the anatomy and its functions and associated abnormalities. The modalities of Bell's Palsy therapy are with corticosteroids and antivirals, facial exercises, electrostimulation, physiotherapy and decompression operations. Approximately 80-90% of patients with Bell's palsy recover completely within 6 months, even in 50-60% of cases improved within 3 weeks. Approximately 10% experienced persistent facial muscle asymmetry, and 5% experienced severe sequelae, and 8% of cases were recurrent.

Eight patients with Bell palsy were evaluated with Gd-DTPA (Magnevist)-enhanced MR imaging in a 1.0-T Siemen's Magnetom unit. Axial pre-and postcontrast and coronal postcontrast T1-weighted MR images of facial nerves were studied. Significant unilateral enhancement of the facial nerve within the internal auditory canal, with or without involvement of the geniculate ganglia, was found in six patients. Three of these patients without satisfactory response to medical treatment underwent surgical decompression, with excellent recovery of facial nerve function. The authors believe that gadolinium-enhanced MR imaging is valuable in the evaluation and management of Bell palsy

Third nerve palsy (TNP) caused by a posterior communicating artery (PCoA) aneurysm is a well-known symptom of the condition, but the characteristics of unruptured PCoA aneurysm-associated third nerve palsy have not been fully evaluated. The aim of this study was to analyze the anatomical features of PCoA aneurysms that caused TNP from the viewpoint of the relationship between the ICA and the skull base. Forty-eight unruptured PCoA aneurysms were treated surgically between January 2008 and September 2013. The characteristics of the aneurysms were evaluated. Thirteen of the 48 patients (27%) had a history of TNP. The distance between the ICA and the anterior-posterior clinoid process (ICA-APC distance) was significantly shorter in the TNP group (pPCoA aneurysms can cause third nerve palsy if the ICA runs close to the skull base.

Hontanilla, Bernardo; Marre, Diego; Cabello, Alvaro

2014-01-01

Although in most cases Bell palsy resolves spontaneously, approximately one-third of patients will present sequela including facial synkinesis and paresis. Currently, the techniques available for reanimation of these patients include hypoglossal nerve transposition, free muscle transfer, and cross-face nerve grafting (CFNG). Between December 2008 and March 2012, eight patients with incomplete unilateral facial paralysis were reanimated with two-stage CFNG. Gender, age at surgery, etiology of paralysis denervation time, donor and recipient nerves, presence of facial synkinesis, and follow-up were registered. Commissural excursion and velocity and patient satisfaction were evaluated with the FACIAL CLIMA and a questionnaire, respectively. Mean age at surgery was 33.8 ± 11.5 years; mean time of denervation was 96.6 ± 109.8 months. No complications requiring surgery were registered. Follow-up period ranged from 7 to 33 months with a mean of 19 ± 9.7 months. FACIAL CLIMA showed improvement of both commissural excursion and velocity greater than 75% in 4 patients, greater than 50% in 2 patients, and less than 50% in the remaining two patients. Qualitative evaluation revealed a high grade of satisfaction in six patients (75%). Two-stage CFNG is a reliable technique for reanimation of incomplete facial paralysis with a high grade of patient satisfaction.

Peripheral facial weakness is a facial nerve damage that results in muscle weakness on one side of the face. It may be idiopathic (Bell's palsy) or may have a detectable cause. Almost 80% of peripheral facial weakness cases are primary and the rest of them are secondary. The most frequent causes of secondary peripheral facial weakness are systemic viral infections, trauma, surgery, diabetes, local infections, tumor, immune disorders, drugs, degenerative diseases of the central nervous system, etc. The diagnosis relies upon the presence of typical signs and symptoms, blood chemistry tests, cerebrospinal fluid investigations, nerve conduction studies and neuroimaging methods (cerebral MRI, x-ray of the skull and mastoid). Treatment of secondary peripheral facial weakness is based on therapy for the underlying disorder, unlike the treatment of Bell's palsy that is controversial due to the lack of large, randomized, controlled, prospective studies. There are some indications that steroids or antiviral agents are beneficial but there are also studies that show no beneficial effect. Additional treatments include eye protection, physiotherapy, acupuncture, botulinum toxin, or surgery. Bell's palsy has a benign prognosis with complete recovery in about 80% of patients, 15% experience some mode of permanent nerve damage and severe consequences remain in 5% of patients.

Bell’s palsy: data from a study of 70 cases

Science.gov (United States)

Cirpaciu, D; Goanta, CM

2014-01-01

Bell’s palsy is a condition that affects the facial nerve, which is one of the twelve cranial nerves. Its main function is to control all the muscles of the facial expression. It is a unilateral, acute, partial or complete paralysis of the facial nerve. Bell's palsy remains the most common cause of facial nerve paralysis, more often encountered in females aged 17 to 30 years, recurrent in many cases and with poor associations with other pathologic conditions. In modern literature, the suspected etiology could be due to the reactivation of the latent herpes viral infections in the geniculate ganglia, and their subsequent migration to the facial nerve but, favorable outcome by using vasodilators, neurotrophic and corticosteroid therapy was recorded.

The hypoglossal canal and the origin of human vocal behavior

Science.gov (United States)

Kay, Richard F.; Cartmill, Matt; Balow, Michelle

1998-01-01

The mammalian hypoglossal canal transmits the nerve that supplies the muscles of the tongue. This canal is absolutely and relatively larger in modern humans than it is in the African apes (Pan and Gorilla). We hypothesize that the human tongue is supplied more richly with motor nerves than are those of living apes and propose that canal size in fossil hominids may provide an indication about the motor coordination of the tongue and reflect the evolution of speech and language. Canals of gracile Australopithecus, and possibly Homo habilis, fall within the range of extant Pan and are significantly smaller than those of modern Homo. The canals of Neanderthals and an early “modern” Homo sapiens (Skhul 5), as well as of African and European middle Pleistocene Homo (Kabwe and Swanscombe), fall within the range of extant Homo and are significantly larger than those of Pan troglodytes. These anatomical findings suggest that the vocal capabilities of Neanderthals were the same as those of humans today. Furthermore, the vocal abilities of Australopithecus were not advanced significantly over those of chimpanzees whereas those of Homo may have been essentially modern by at least 400,000 years ago. Thus, human vocal abilities may have appeared much earlier in time than the first archaeological evidence for symbolic behavior. PMID:9560291

Objective: To compare the frequency of recurrent laryngeal nerve(s) (RLNs) palsy after various thyroid procedures with and without identification of recurrent laryngeal nerve during the operation. Study Design: Randomized controlled trial. Place and Duration of Study: Department of Surgery, Military Hospital, Rawalpindi, from August 2008 to April 2010. Methodology: Patients undergoing indirect laryngoscopy with normal vocal cords and those with carcinoma and re-do surgery having normal vocal cord were included in the study. Patients with hoarseness of voice, abnormal vocal cord movements and with solitary nodule in the isthmus were excluded. These patients were randomly divided into 2 groups of 50 each using random number tables. RLN was identified by exposing the inferior thyroid artery and traced along its entire course in group-A. Whereas, in group-B, nerves were not identified during the operations. Immediate postoperative direct laryngoscopy was performed by a surgeon with the help of an anaesthesiologist for the assessment of vocal cords. Patients with persistent hoarseness of voice were followed-up with indirect laryngoscopy at 3 and 6 months. Results: Temporary unilateral recurrent laryngeal nerve palsies occurred in 2 (4%) patients in group-A where the voice and cord movements returned to normal in 6 months. In group-B, it occurred in 8 (16%) patients, 2 bilateral (4%) injuries requiring tracheostomy and 6 unilateral injuries (12%). Among the 2 bilateral recurrent laryngeal nerve injuries, the tracheostomy was removed in one case after 6 months with persistent hoarseness of voice but no respiratory difficulty during routine activities. Tracheostomy was permanent in the other case. Among the 6 cases of unilateral nerve injuries, the voice improved considerably in 4 cases within 6 months but in 2 cases hoarseness persisted even after 6 months. Frequency of recurrent laryngeal nerve palsies was significantly lower in group-A as compared to group-B (p = 0

Femoral nerve palsy caused by ileopectineal bursitis after total hip replacement: a case report

Directory of Open Access Journals (Sweden)

Bähr Mathias

2011-05-01

Full Text Available Abstract Introduction Infectious ileopectineal bursitis is a rare complication after total hip replacement and is associated mainly with rheumatoid arthritis. The main complications are local swelling and pain, but communication of the inflamed bursa with the joint can occur, leading to subsequent cartilage damage and bone destruction. Case presentation We report a case of a 47-year-old Caucasian woman without rheumatoid arthritis who reported pain and palsy in her left leg almost one year after total hip replacement. She was diagnosed with an ileopectineal bursitis after total hip replacement, leading to femoral nerve palsy. The diagnosis was obtained by thorough clinical examination, the results of focused computed tomography and magnetic resonance imaging. Conclusion To the best of our knowledge, this is the first report of non-infectious ileopectineal bursitis in a patient without rheumatoid arthritis as a complication of total hip replacement. This rare case underlines the importance of proper neurologic examination of persistent conditions after orthopedic intervention in otherwise healthy individuals. We believe this case should be useful for a broad spectrum of medical specialties, including orthopedics, neurology, radiology, and general practice.

Cavalcanti, Daniel D; Garcia-Gonzalez, Ulises; Agrawal, Abhishek; Tavares, Paulo L M S; Spetzler, Robert F; Preul, Mark C

2010-07-01

The lower cranial nerves must be identified to avoid iatrogenic injury during skull base and high cervical approaches. Prompt recognition of these structures using basic landmarks could reduce surgical time and morbidity. The anterior triangle of the neck was dissected in 30 cadaveric head sides. The most superficial segments of the glossopharyngeal, vagus and its superior laryngeal nerves, accessory, and hypoglossal nerves were exposed and designated into smaller anatomic triangles. The midpoint of each nerve segment inside the triangles was correlated to the angle of the mandible (AM), mastoid tip (MT), and bifurcation of the common carotid artery. A triangle bounded by the styloglossus muscle, external carotid artery, and facial artery housed the glossopharyngeal nerve. This nerve segment was 0.06 ± 0.71 cm posterior to the AM and 2.50 ± 0.59 cm inferior to the MT. The vagus nerve ran inside the carotid sheath posterior to internal carotid artery and common carotid artery bifurcation in 48.3% of specimens. A triangle formed by the posterior belly of digastric muscle, sternocleidomastoid muscle, and internal jugular vein housed the accessory nerve, 1.90 ± 0.60 cm posterior to the AM and 2.30 ± 0.57 cm inferior to the MT. A triangle outlined by the posterior belly of digastric muscle, internal jugular vein, and common facial vein housed the hypoglossal nerve, which was 0.82 ± 0.84 cm posterior to the AM and 3.64 ± 0.70 cm inferior to the MT. Comprehensible landmarks can be defined to help expose the lower cranial nerves to avoid injury to this complex region. Copyright © 2010 Elsevier Inc. All rights reserved.

Common questions about Bell palsy.

Science.gov (United States)

Albers, Janet R; Tamang, Stephen

Bell palsy is an acute affliction of the facial nerve, resulting in sudden paralysis or weakness of the muscles on one side of the face. Testing patients with unilateral facial paralysis for diabetes mellitus or Lyme disease is not routinely recommended. Patients with Lyme disease typically present with additional manifestations, such as arthritis, rash, or facial swelling. Diabetes may be a comorbidity of Bell palsy, but testing is not needed in the absence of other indications, such as hypertension. In patients with atypical symptoms, magnetic resonance imaging with contrast enhancement can be used to rule out cranial mass effect and to add prognostic value. Steroids improve resolution of symptoms in patients with Bell palsy and remain the preferred treatment. Antiviral agents have a limited role, and may improve outcomes when combined with steroids in patients with severe symptoms. When facial paralysis is prolonged, surgery may be indicated to prevent ocular desiccation secondary to incomplete eyelid closure. Facial nerve decompression is rarely indicated or performed. Physical therapy modalities, including electrostimulation, exercise, and massage, are neither beneficial nor harmful.

Diagnosis and management of patients with Bell's palsy.

Science.gov (United States)

Mooney, Tracy

Bell's palsy (idiopathic facial paralysis) is the most common cause of acute unilateral facial nerve paralysis. Although it is usually a self-limiting condition, it can be distressing for the patient. Many people who experience one-sided facial paralysis fear that it is a symptom of stroke. However, there are subtle differences between Bell's palsy and stroke. This article discusses potential causes of the condition and identifies the differences between Bell's palsy and stroke. In addition, appropriate strategies for the care of patients with the condition are suggested. Management includes antiviral medication, corticosteroid therapy, eye care, botulinum toxin type A injection, physiotherapy, surgery and acupuncture. Psychological and emotional care of these patients is also important because any facial disability caused by facial nerve paralysis can result in anxiety and stress.

Facial nerve disorders may be of sudden onset and more often of unknown etiology. Edema of the facial nerve within the fallopian canal results in Bell's palsy. This causes compression of the nerve and affects the microcirculation. Many authors have suggested treatment for facial nerve paralysis ranging from simple physiotherapy to complicated microvascular decompression. It more often results in symptoms like synkinesis and muscle spasm after the decompression surgery of the nerve because of ...

Traumatic injuries of the abducens nerve as a consequence of facial and/or head trauma occur with or without associated cervical or skull base fracture. This is the first report on unilateral avulsion of the abducens nerve in a 29-year-old man with severe right facial trauma. In addition, he exhibited mild left facial palsy, and moderate left hearing disturbance. Magnetic resonance imaging (MRI) using fast imaging employing steady-state acquisition (FIESTA) revealed avulsion of left sixth cranial nerve. We recommend thin-slice MR examination in patients with abducens palsy after severe facial and/or head trauma.

Common peroneal nerve palsy leading to foot drop is difficult to manage and has historically been treated with extended bracing with expectant waiting for return of nerve function. Peroneal nerve exploration has traditionally been avoided except in cases of known traumatic or iatrogenic injury, with tendon transfers being performed in a delayed fashion after exhausting conservative treatment. We present a new strategy for management of foot drop with nerve exploration and concomitant tendon transfer. We retrospectively reviewed a series of 12 patients with peroneal nerve palsies that were treated with tendon transfer from 2005 to 2011. Of these patients, seven were treated with simultaneous peroneal nerve exploration and repair at the time of tendon transfer. Patients with both nerve repair and tendon transfer had superior functional results with active dorsiflexion in all patients, compared to dorsiflexion in 40% of patients treated with tendon transfers alone. Additionally, 57% of patients treated with nerve repair and tendon transfer were able to achieve enough function to return to running, compared to 20% in patients with tendon transfer alone. No patient had full return of native motor function resulting in excessive dorsiflexion strength. The results of our limited case series for this rare condition indicate that simultaneous nerve repair and tendon transfer showed no detrimental results and may provide improved function over tendon transfer alone.

Idiopathic Non-traumatic Facial Nerve Palsy (Bell’s Palsy) in Neonates; An Atypical Age and Management Dilemma

Science.gov (United States)

Khair, Abdulhafeez M.; Ibrahim, Khalid

2018-01-01

Idiopathic (Bell’s) palsy is the commonest cause of unilateral facial paralysis in children. Although being idiopathic by definition, possible infectious, inflammatory, and ischemic triggers have been suggested. Bell’s palsy is thought to be responsible for up to three-fourths of cases of acute unilateral facial paralysis worldwide. The diagnosis has to be reached after other causes of acute peripheral palsy have been excluded. However, it is rarely described in neonates and young infants. Steroids may have some role in treatment, but antiviral therapies have doubtful evidence of benefit. Prognosis is good, though residual dysfunction is occasionally encountered. We report the case of a two-week-old neonate with no prior illnesses who presented with acute left facial palsy. Clinical findings and normal brain imaging were consistent with the diagnosis of Bell’s palsy. The patient had a good response to oral steroids. PMID:29468002

Full Text Available Clivus fractures are a rare pathology, frecuently associated tohigh power trauma. Such injuries may be associated with vascular and cranial nerves lesions. The abducens nerve is particularly vulnerable to traumatic injuries due to its long intracranial course, since their real origin until the lateral rectus muscle. The unilateral abducens nerve palsy of 1- 2-7% occurs in patients with cranial trauma, bilateral paralysis is rare. We report a patient who presented bilateral abducens nerve palsy associated with a clivus fracture

Full Text Available Acupuncture is a common and effective therapeutic method to treat facial nerve palsy (FNP. However, its underlying mechanism remains unclear. This study was aimed to investigate the effects of electroacupuncture on symptoms and content of HSV-1 DNA in FNP mice. Mice were randomized into four groups, an electroacupuncture treatment group, saline group, model animal group, and blank control group. Electroacupuncture was applied at Jiache (ST6 and Hegu (LI4 in electroacupuncture group once daily for 14 days, while electroacupuncture was not applied in model animal group. In electroacupuncture group, mice recovered more rapidly and HSV-1 DNA content also decreased more rapidly, compared with model animal group. We conclude that electroacupuncture is effective to alleviate symptoms and promote the reduction of HSV-1 in FNP.

A 67-year-old man presented with hoarseness, dysarthria and deviation of the tongue to the left side the day after the open-heart operation under general anesthesia. Brain MRI demonstrated no causal lesion, and laryngoscope showed left vocal cord abductor palsy, so we diagnosed him with Tapia's syndrome (i.e., concomitant paralysis of the left recurrent and hypoglossal nerve). His neurological symptoms recovered gradually and improved completely four months after the onset. Tapia's syndrome is a rare condition caused by the extra cranial lesion of the recurrent laryngeal branch of the vagus nerve and the hypoglossal nerve, and mostly described as a complication of tracheal intubation. In this case, transesophageal echo probe has been held in the left side of the pharynx, so compression to the posterior wall of pharynx by the probe resulted in this condition, and to the best of our knowledge, this is the first report of Tapia's syndrome due to transesophageal echocardiography during an open-heart operation. This rare syndrome should be considered as a differential diagnosis of dysarthria and tongue deviation after a procedure associated with compression to the pharynx.

Clinical studies on Bell's palsy

Yamada, Yoshio

1985-01-01

The purpose of this study was to evaluate the diagnostic value of the salivary gland scintigraphy using sup(99m)Tc-pertechnetate for the prognosis of Bell's palsy. The salivary gland scintigraphy was performed in 40 patients with Bell's palsy and 15 normal subjects. After intravenous injection of 10 mCt of sup(99m)Tc-pertechnetate, sequential scintigrams were taken with a scintillation camera every one minute for 25 minutes. At 15 minutes after injection, both of normal subjects and patients were given ascorbic acid to stimulate the secretion of saliva. By the present method, the time activity curve was examined for the regions of interest over the parotid and submandibular glands and backgrounds. In normal subjects, values of the concentration and excretory ratio between the right and left sides of the parotid and submandibular glands were more than 80%. Some patients with Bell's palsy showed a decreased concentration and/or excretory ratio less than 80% between the normal and affected sides of the parotid glands. This suggests a functional involvement of the facial nerve in the salivary secretion from the parotid glands. On examination within 10 days of the onset of Bell's palsy, 31 cases with complete recovery showed values of the concentration ratio and/or excretory ratio more than 80% between the normal and affected sides of the submandibular glands. In contrast, 9 cases with imcomplete recovery showed low values of the concentration ratio and excretory ratio less than 80%. In the latter, more active treatments such as decompression operation should be considerd in the early stage of the palsy. The salivary scintigraphy using sup(99m)Tc-pertechnetate is more valuable as an early prognostic indicator for Bell's palsy compared with other prognostic tests such as the lid vibration test, the stapedial reflex test, the electrogustometry, the nerve excitability test and the evoked electromyography.

Handlebar palsy--a compression syndrome of the deep terminal (motor) branch of the ulnar nerve in biking.

Science.gov (United States)

Capitani, Daniel; Beer, Serafin

2002-10-01

We describe 3 patients who developed a severe palsy of the intrinsic ulnar supplied hand muscles after bicycle riding. Clinically and electrophysiologically all showed an isolated lesion of the deep terminal motor branch of the ulnar nerve leaving the hypothenar muscle and the distal sensory branch intact. This type of lesion at the canal of Guyon is quite unusual, caused in the majority of cases by chronic external pressure over the ulnar palm. In earlier reports describing this lesion in bicycle riders, most patients experienced this lesion after a long distance ride. Due to the change of riding position and shape of handlebars (horn handle) in recent years, however, even a single bicycle ride may be sufficient to cause a lesion of this ulnar branch. Especially in downhill riding, a large part of the body weight is supported by the hand on the corner of the handlebar leading to a high load at Guyon's canal. As no sensory fibres are affected, the patients are not aware of the ongoing nerve compression until a severe lesion develops. Individual adaptation of the handlebar and riding position seems to be crucial for prevention of this type of nerve lesion.

Bell's palsy is considered the most common cause of facial nerve paralysis in children. Although different theories have been postulated for its diagnosis, reactivation of the Varicella zoster virus (VZV) has been implicated as one of the causes of Bell's palsy. The aim of the study was to evaluate the association of Varicella-zoster virus infection with Bell's palsy and its outcome in children. A total of 30 children with Bell's palsy were recruited and were assayed for evidence of VZV infection. The severity of facial nerve dysfunction and the recovery rate were evaluated according to House-Brackmann Facial Nerve Grading Scale (HB FGS). Paired whole blood samples from all patients were obtained at their initial visit and 3 weeks later, and serum samples were analyzed for VZV IgG and IgM antibodies using ELISA. A significantly higher percentage of Bell's palsy patients were seropositive for VZV IgM antibodies than controls (36.6% of patients vs 10% of controls) while for VZV IgG antibodies the difference was statistically nonsignificant. HB FGS in Bell's palsy patients with serologic evidence of VZV recent infection or reactivation showed a statistiacally significant less cure rate than other patients. VZV reactivation may be an important cause of acute peripheral facial paralysis in children. The appropriate diagnosis of VZV reactivation should be done to improve the outcome and the cure rate by the early use of antiviral treatment. Copyright © 2014 Elsevier Ireland Ltd.

MRI enhancement of the facial nerve with Gd-DTPA, 2

International Nuclear Information System (INIS)

Yanagida, Masahiro

1993-01-01

We performed enhanced MRI using Gd-DTPA in 84 patients with facial palsy. After assessing enhancement of the normal facial nerve, we examined enhancement in patients with Bell's palsy and Ramsay Hunt syndrome. In 95% of patients with Bell's palsy, enhancement was obtained in the distal IAC and labyrinthine portions. In 72%, enhancement was significant from the distal IAC portion through the vertical portion. In some of the patients who underwent enhanced MRI twice, increased signal intensity was observed in distal portions such as the vertical portion. In many cases of Ramsay Hunt syndrome, enhancement was seen extensively in the IAC portion through the vertical portion. In the subjects with internal auditory symptoms such as vertigo and tinnitus, enhancement of the IAC portion was seen not only in the facial nerve but also in the vestibular and the cochlear nerves. These results suggest that the vascular permeability of lesions in Bell's palsy may be increased from the distal IAC portion to the vertical portion. Judging from the present findings with Ramsay Hunt syndrome, symptoms related to the enhanced portions suggest that accompanying internal auditory symptoms occur due to inflammation of the IAC portions of cochlear and vestibular nerves.

Our experience of 3 cases with dysphagia due to cranial nerve palsy as a late complication after radiation therapy for nasopharyngeal carcinoma (NPC) is herein reported. The cases consisted of two males and one female, ranging in age from 20 to 41 years old at the time of radiation therapy. Two cases received conventional radiation therapy alone while one case was given a combination of chemotherapy and radiotherapy. All patients began to suffer from dysphagia from eight to fifteen weeks after the therapy. All cases had bilateral hypoglossal nerve palsy with several sensory and motor disturbances of the pharynx and larynx. The method of intermittent oral-esophageal tube feeding was performed in one case, however, the other one case had to undergo a total laryngectomy in order to prevent aspiration pneumonia. Recently, the combination of chemotherapy and radiotherapy is frequently performed in order to improve prognosis of NPC. As a result, the occurrence of dysphagia associated with this therapeutic regimen and caused by a late disturbance of the cranial nerve may therefore increase in future. (author)

Cranial nerve palsies in childhood parameningeal rhabdomyosarcoma.

Children with parameningeal rhabdomyosarcoma (PM RMS) and cranial nerve palsy (CNP) are at risk for permanent neurologic dysfunction. Clinicians often consider the use of emergent therapies such as expedited radiation and/or corticosteroids; however, there is a paucity of information describing the natural history of CNP in PM RMS. We sought to describe the clinical features of patients with PM RMS plus associated CNP and to evaluate the patient, disease, and treatment-related factors that impacted neurologic recovery. We conducted a retrospective review of PM RMS cases treated at the Hospital for Sick Children between 1985 and 2010. Thirty-five children were treated for PM RMS, 19 (54%) of whom presented with CNP. Children with CNP were nine times more likely to have other high-risk features (cranial base bony erosion and/or intracranial extension) at the time of presentation than children without CNP (OR 9.6, 95% CI 1.69, 54.79, P = 0.013). In addition to commencing chemotherapy, 13 patients (68%) received expedited RT and corticosteroids, four (21%) corticosteroids alone, and two (11%) received only standard chemotherapy and RT. At last follow up of the 11 survivors, neurologic recovery was complete in five (45%), partial in five (45%), and absent in one (9%). In our cohort, recovery of PM RMS associated CNP was often incomplete despite multi-modal therapy. A larger cohort of patients is required to determine the utility of emergent initiation of radiation or corticosteroids. This study will facilitate the counseling of future families on the long-term neurologic recovery CNP in PM RMS. Copyright © 2012 Wiley Periodicals, Inc.

Sudden headache, third nerve palsy and visual deficit: thinking outside the subarachnoid haemorrhage box.

Ní Chróinín, Danielle; Lambert, John

2013-11-01

A 75-year-old lady presented with sudden severe headache and vomiting. Examination was normal, and CT and lumbar puncture not convincing for subarachnoid haemorrhage. Shortly thereafter, she developed painless diplopia. Examination confirmed right third cranial nerve palsy plus homonymous left inferior quadrantanopia. Urgent cerebral MRI with angiography was requested to assess for a possible posterior communicating artery aneurysm, but revealed an unsuspected pituitary mass. Pituitary adenoma with pituitary apoplexy was diagnosed. Pituitary apopolexy is a syndrome comprising sudden headache, meningism, visual and/or oculomotor deficits, with an intrasellar mass. It is commonly due to haemorrhage or infarction within a pituitary adenoma. Treatment includes prompt steroid administration, and potentially surgical decompression. While subarachnoid haemorrhage is an important, well-recognised cause of sudden severe headache, other aetiologies, including pituitary apoplexy, should be considered and sought.

3D-FT MRI of the facial nerve

Girard, N.; Raybaud, C.; Poncet, M.

1994-01-01

Contrast-enhanced 3D-FT MRI of the intrapetrous facial nerve was obtained in 38 patients with facial nerve disease, using a 1.0 T magnet and fast gradient-echo acquisition sequences. Contiguous millimetric sections were obtained, which could be reformatted in any desired plane. Acutely ill patients, were examined within the first 2 months, included: 24 with Bell's palsy and 6 with other acute disorders (Herpes zoster, trauma, neuroma, meningeal metastasis, middle ear granuloma). Six patients investigated more than a year after the onset of symptoms included 3 with congenital cholesteatoma, 2 with neuromas and one with a chronic Bell's palsy. The lesion was found incidentally in two cases (a suspected neurofibroma and a presumed drop metastasis from an astrocytoma). Patients with tumours had nodular, focally-enhancing lesions, except for the leptomeningeal metastasis in which the enhancement was linear. Linear, diffuse contrast enhancement of the facial nerve was found in trauma, and in the patient with a middle ear granuloma. Of the 24 patients with an acute Bell's palsy 15 exhibited linear contrast enhancement of the facial nerve. Three of these were lost to follow-up, but correlation of clinical outcome and contrast enhancement showed that only 4 of the 11 patients who made a complete recovery and all 10 patients with incomplete recovery demonstrated enhancement. Possible explanations for these findings are suggested by pathological data from the literature. 3D-FT imaging of the facial nerve thus yields direct information about the of the nerve condition and defines the morphological abnormalities. It can also demonstrate contrast enhancement which seems to have some prognostic value in acute idiopathic Bell's palsy. (orig.)

Intratemporal Facial Nerve Paralysis- A Three Year Study

Full Text Available Introduction This study on intratemporal facial paralysis is an attempt to understand the aetiology of facial nerve paralysis, effect of different management protocols and the outcome after long-term follow-up. Materials and Methods A prospective longitudinal study was conducted from September 2005 to August 2008 at the Department of Otorhinolaryngology of a medical college in Kolkata comprising 50 patients of intratemporal facial palsy. All cases were periodically followed up for at least 6 months and their prognostic outcome along with different treatment options were analyzed. Result Among different causes of facial palsy, Bell’s palsy is the commonest cause; whereas cholesteatoma and granulation were common findings in otogenic facial palsy. Traumatic facial palsies were exclusively due to longitudinal fracture of temporal bone running through geniculate ganglion. Herpes zoster oticus and neoplasia related facial palsies had significantly poorer outcome. Discussion Otogenic facial palsy showed excellent outcome after mastoid exploration and facial decompression. Transcanal decompression was performed in traumatic facial palsies showing inadequate recovery. Complete removal of cholesteatoma over dehiscent facial nerve gave better postoperative recovery. Conclusion The stapedial reflex test is the most objective and reproducible of all topodiagnostic tests. Return of the stapedial reflex within 3 weeks of injury indicates good prognosis. Bell’s palsy responded well to conservative measures. All traumatic facial palsies were due to longitudinal fracture and 2/3rd of these patients showed favourable outcome with medical therapy.

Gd-DTPA enhanced MR imaging in Bell's palsy

1991-01-01

Magnetic resonance imaging (MRI) was carried out in 27 patients with Bell's palsy. T1-weighted spin-echo images (TR500/TE25-34) were taken before and after the intravenous administration of Gd-DTPA (0.1 mmol/kg) with 0.5T superconductive MRI. There was significant enhancement at the geniculate ganglion and the horizontal segment of the involved facial nerve in 22 patients (81.5%) and at the vertical segment in 20 (74.1%). Enhancement at the meatal fundus was seen in only 4 patients (14.9%) and at the labyrinthine segment in 8 (29.6%). These results corroborate other evidence that the geniculate ganglion is involved most frequently in Bell's palsy. In addition, the enhancement of the proximal portion, i.e. the meatal fundus and the labyrinthine segment of the nerve, although not common, noted in this study may be important in the diagnosis and treatment of Bell's palsy.

In this report, the relationship of acoustic neuromas to the adjacent cranial nerves is discussed. On T{sub 1}-weighted images, the trigeminal nerve was detected in all 13 cases. Mild to marked compression of these nerves by the tumors was observed in eight cases. The extent of compression did not always correspond to the clinical symptoms. In four cases with a maximum tumor diameter of 2 cm or less, the 7th and 8th cranial nerves were identified. There was no facial palsy in these patients. Two patients with a tumor diameter of more than 2 cm also had no facial palsy. All patients, including those with small tumors, complained of hearing loss and/or tinnitus. While MR imaging has some limitations, it is an effective imaging modality for showing the relationship between tumors and nerves. (author).

Facial nerve paralysis in children

2015-01-01

Facial nerve palsy is a condition with several implications, particularly when occurring in childhood. It represents a serious clinical problem as it causes significant concerns in doctors because of its etiology, its treatment options and its outcome, as well as in little patients and their parents, because of functional and aesthetic outcomes. There are several described causes of facial nerve paralysis in children, as it can be congenital (due to delivery traumas and genetic or malformative diseases) or acquired (due to infective, inflammatory, neoplastic, traumatic or iatrogenic causes). Nonetheless, in approximately 40%-75% of the cases, the cause of unilateral facial paralysis still remains idiopathic. A careful diagnostic workout and differential diagnosis are particularly recommended in case of pediatric facial nerve palsy, in order to establish the most appropriate treatment, as the therapeutic approach differs in relation to the etiology.

Previous studies have attempted to determine the best treatment for oculomotor nerve palsy (ONP) secondary to posterior communicating artery (PCoA) aneurysms, but have been limited by small sample sizes and limited treatment. To analyze the treatment of ONP secondary to PCoA with both coiling and clipping in ruptured and unruptured aneurysms. Data from 2 large academic centers was retrospectively collected over 22 years, yielding a total of 93 patients with ONP secondary to PCoA aneurysms. These patients were combined with 321 patients from the literature review for large data analyses. Onset symptoms, recovery, and time to resolution were evaluated with respect to treatment and aneurysm rupture status. For all patients presenting with ONP (n = 414) 56.6% of those treated with microsurgical clipping made a full recovery vs 41.5% of those treated with endovascular coil embolization (P = .02). Of patients with a complete ONP (n = 229), full recovery occurred in 47.3% of those treated with clipping but in only 20% of those undergoing coiling (P = .01). For patients presenting with ruptured aneurysms (n = 130), full recovery occurred in 70.9% compared with 49.3% coiled patients (P = .01). Additionally, although patients with full ONP recovery had a median time to treatment of 4 days, those without full ONP recovery had a median time to treatment of 7 days (P = .01). Patients with ONP secondary to PCoA aneurysms treated with clipping showed higher rates of full ONP resolution than patients treated with coil embolization. Larger prospective studies are needed to determine the true potential of recovery associated with each treatment.

Electromyography-guided phrenic nerve (PN) monitoring using a catheter positioned in a hepatic vein can aid in preventing phrenic nerve palsy (PNP) during cryoballoon ablation for atrial fibrillation. We wanted to evaluate the feasibility and efficacy of PN monitoring during procedures using second-generation cryoballoons. This study included 140 patients (43 women) in whom pulmonary vein isolation was performed using a second-generation cryoballoon. Electromyography-guided PN monitoring was performed by pacing the right PN at 60 per minute and recording diaphragmatic compound motor action potential (CMAP) via a quadripolar catheter positioned in a hepatic vein. If a 30% decrease in CMAP amplitude was observed, cryoapplication was discontinued with forced deflation to avoid a PNP. Monitoring was unfeasible in 8 of 140 patients (5.7%), PNP occurred in 1. Stable CMAP amplitudes were achieved before ablation in 132 of 140 patients (94.3%). In 18 of 132 patients (13.6%), a 30% decrease in CMAP amplitude occurred and cryoablation was discontinued. Each time, recovery of CMAP amplitude took <60 s. In 9 of 18 cases, a second cryoapplication in the same pulmonary vein was safely performed. We observed no PNP or complication related to electromyography-guided PN monitoring. Electromyography-guided PN monitoring using a catheter positioned in a hepatic vein seems feasible and effective to prevent PNP during cryoballoon ablation using second-generation cryoballoon. © 2015 American Heart Association, Inc.

We examined a series of 21 peripheral facial palsy patients attempted to ( 17 Bell's palsy, 4 Hunt syndrome) with Gd-DTPA-enhanced MRI and attempted to determine the relation between prognosis and MRI findings. We divided patients into two groups based on facial palsy scores of Japanese facial nerve research; a good group (G-Group) and a bad group (B-group). The G-group scored over 20 points on the 20th day after the first visit and the B-group under 20 points. G-group consisted of 9 Bell's palsy and 1 Hunt syndrome patients, and the B-group of 8 Bell's palsy and 3 Hunt syndrome patients. The averaged facial palsy score of both groups was analyzed every week during 4 weeks. Recovery from the palsy was better in the G-group than the B-group (P<0.05); the scores at the 4th week of the G- and B-groups were 32.6±15.2 and 7.8±7.4, respectively. The MRI findings of both groups were examined retrospectively. Nine of 10 G-group and nine of 11 B-group patients had abnormal contrast enhancement. The result of enhanced facial nerve segment was as follows: G-group, auditory canal 1, labyrinthine/geniculate 7, tympanic 7, mastoid 7: B-group, auditory canal 2, labyrinthine/geniculate 8, tympanic 8, mastoid 7. Our results indicate no relation between the prognosis and the MRI findings. Therefore, it is impossible to predict the prognosis of facial palsy from the results of Gd-DTPA-enhanced MRI. (author)

The authors report a case of invasive aspergillosis of a sphenoid sinus mucocele revealed in a patient with diabetes in Djibouti by homolateral palsy of the 3rd, 4th, 5th and 6th nerves. This rare condition occurs preferentially in immunodeficient subjects. Because of its clinical polymorphism, its diagnosis is difficult and is often not made until complications develop. Endonasal surgery with anatomopathological and mycological examination is both a diagnostic and therapeutic procedure. It must be performed early, to avoid functional or even life-threatening complications.

Also, we studied possible neural mechanisms involved in B210 treatment and subsequent reduced snoring in rats.Methods and result: We compared pressure and frequency of snoring, activities of phrenic nerve (PNA, activities of recurrent laryngeal nerve (RLNA and activities of hypoglossal nerve (HNA, inspiratory time (TI and expiratory time (TE of PNA, and pre-inspiratory time (Pre-TI of HNA in aged rats between sham and B210 treatment groups (30 mg/mL dissolved in DMSO. We found that aged rats that received B210 treatment had significantly reduced pressure and frequency of snoring than rats who received sham treatment. Also, we observed that aged rats that received B210 treatment had significantly increased PNA, RLNA, and HNA, extended TI and TE of PNA, and prolonged Pre-TI of HNA compared to rats that received sham treatment. In other words, B210 treatment may relieve snoring through modulating activities and breathing time of upper airway related nerves in aged rats.Conclusion: We suggested that the B210 might be a potential herbal formula for snoring remission.Keywords: Chinese herbal medicine, snoring remission, upper airway, phrenic nerve, recurrent laryngeal nerve, hypoglossal nerve

Idiopathic peripheral facial palsy, also named Bell's palsy, is the most common cause of peripheral facial palsy in adults. Although it is considered as a benign condition, its social and psychological impact can be dramatic, especially in the case of incomplete recovery. The main pathophysiological hypothesis is the reactivation of HSV 1 virus in the geniculate ganglia, leading to nerve edema and its compression through the petrosal bone. Patients experience an acute (less than 24 hours) motor deficit involving ipsilateral muscles of the upper and lower face and reaching its peak within the first three days. Frequently, symptoms are preceded or accompanied by retro-auricular pain and/or ipsilateral face numbness. Diagnosis is usually clinical but one should look for negative signs to eliminate central facial palsy or peripheral facial palsy secondary to infectious, neoplastic or autoimmune diseases. About 75% of the patients will experience spontaneous full recovery, this rate can be improved with oral corticotherapy when introduced within the first 72 hours. To date, no benefit has been demonstrated by adding an antiviral treatment. Hemifacial spasms (involuntary muscles contractions of the hemiface) or syncinesia (involuntary muscles contractions elicited by voluntary ones, due to aberrant reinnervation) may complicate the disease's course. Electroneuromyography can be useful at different stages: it can first reveal the early conduction bloc, then estimate the axonal loss, then bring evidence of the reinnervation process and, lastly, help for the diagnosis of complications.

Contrast-enhanced 3D-FT MRI of the intrapetrous facial nerve was obtained in 38 patients with facial nerve disease, using a 1.0 T magnet and fast gradient-echo acquisition sequences. Contiguous millimetric sections were obtained, which could be reformatted in any desired plane. Acutely ill patients, were examined within the first 2 months, included: 24 with Bell's palsy and 6 with other acute disorders (Herpes zoster, trauma, neuroma, meningeal metastasis, middle ear granuloma). Six patients investigated more than a year after the onset of symptoms included 3 with congenital cholesteatoma, 2 with neuromas and one with a chronic Bell's palsy. The lesion was found incidentally in two cases (a suspected neurofibroma and a presumed drop metastasis from an astrocytoma). Patients with tumours had nodular, focally-enhancing lesions, except for the leptomeningeal metastasis in which the enhancement was linear. Linear, diffuse contrast enhancement of the facial nerve was found in trauma, and in the patient with a middle ear granuloma. Of the 24 patients with an acute Bell's palsy 15 exhibited linear contrast enhancement of the facial nerve. Three of these were lost to follow-up, but correlation of clinical outcome and contrast enhancement showed that only 4 of the 11 patients who made a complete recovery and all 10 patients with incomplete recovery demonstrated enhancement. Possible explanations for these findings are suggested by pathological data from the literature. 3D-FT imaging of the facial nerve thus yields direct information about the of the nerve condition and defines the morphological abnormalities. It can also demonstrate contrast enhancement which seems to have some prognostic value in acute idiopathic Bell's palsy. (orig.)

Although many patients with facial paralysis have obtained benefits or completely recovered after acupuncture or electroacupuncture therapy, it is still difficult to list intuitive evidence besides evaluation using neurological function scales and a few electrophysiologic data. Hence, the aim of this study is to use more intuitive and reliable detection techniques such as facial nerve magnetic resonance imaging (MRI), nerve electromyography, and F waves to observe changes in the anatomic morphology of facial nerves and nerve conduction before and after applying acupuncture or electroacupuncture, and to verify their effectiveness by combining neurological function scales. A total of 132 patients with Bell's palsy (grades III and IV in the House-Brackmann [HB] Facial Nerve Grading System) will be randomly divided into electroacupuncture, manual acupuncture, non-acupuncture, and medicine control groups. All the patients will be given electroacupuncture treatment after the acute period, except for patients in the medicine control group. The acupuncture or electroacupuncture treatments will be performed every 2 days until the patients recover or withdraw from the study. The primary outcome is analysis based on facial nerve functional scales (HB scale and Sunnybrook facial grading system), and the secondary outcome is analysis based on MRI, nerve electromyography and F-wave detection. All the patients will undergo MRI within 3 days after Bell's palsy onset for observation of the signal intensity and facial nerve swelling of the unaffected and affected sides. They will also undergo facial nerve electromyography and F-wave detection within 1 week after onset of Bell's palsy. Nerve function will be evaluated using the HB scale and Sunnybrook facial grading system at each hospital visit for treatment until the end of the study. The MRI, nerve electromyography, and F-wave detection will be performed again at 1 month after the onset of Bell's palsy. Chinese Clinical Trials

To evaluate the MRI findings of acute facial nerve paralysis in Bell's palsy and herpes zoster opticus, and to correlate these with the clinical findings. We retrowspectively reviewed the MRI findings in six cases of BEll's palsy(BP) and two of herpes zoster oticus(HZO), and compared them with the findings for 30 normal facial nerves. This nerve was considered abnormal when its signal intensity was greater than that of brain parenchyma or the contralateral normal side on Gd-enhanced T1-weighted axial and coronal MR images. We analysed the location and degree of contrast enhancement, interval change, and clinical progression in correlation with House-Brackmann(HB) grade and electroneuronography (ENoG) findings. Fifteen of 30 normal facial nerves(50%) seen on Gd-enhanced MRI were mildly enhanced in the geniculate ganglion, the proximal tympanic, and the proximal mastoid segment of the facial nerve. No enhancement of the internal auditory canal(IAC) or labyrinthine segment of the facial nerve was noted, however. In BP and HZO, Gd-enhanced MR images revealed fair to marked enhancement for more than two segments from the internal auditory canal to the mastoid segment of the facial nerve. During follow-up MRI, enhancement of the facial nerve varied in location and signal intensity, though gradually decreased in intensity approximately eight weeks after the onset of facial nerve palsy. No correlation between clinical HB grade, ENoG, and follow up MRI findings was noted. Except in the internal auditory canal and labyrinthine segment, normal facial nevemay show mild and relatively symmetrical enhancement. In BP and HZO, the facial nerve showed diffuse enhancement from the IAC to the mastoid segment.=20

Foot drop is a complex symptom with a considerable range in aetiology, severity and prognosis. We aim to characterise the aetiologies of foot drop and assess the diagnostic contribution of neurophysiologic testing (NCS\\/EMG). Retrospective review of consecutive referrals of foot drop to the Neurophysiology Department in Cork University Hospital was performed over a two year period (January 2012 to December 2013). Of a total of 59 referrals, common peroneal nerve (CPN) palsy comprised only slightly more than half of cases; 3(5%) have central origin; 3(5%) have motor neuron disease. Six (10%) have diabetes; 7(12%) have cancer; 5(8%) were bilateral. NCS\\/EMG altered initial working diagnosis in 14 out of 52 (27%) cases whereby initial diagnosis was provided. However one-third of all cases revealed additional coexistent pathology in an anatomic location remote to that of the primary diagnosis. Foot drop with central and proximal localisations are important and under recognised. NCS\\/EMG is valuable and also reveals additional pathology which warrants investigation

To investigate the clinical and electrophysiological features of facial nerve paralysis (FNP) due to benign temporal bone masses (TBMs) and elucidate its differences as compared with Bell's palsy. FNP assessed by the House-Brackmann (HB) grading system and by electroneurography (ENoG) were compared retrospectively. We reviewed 914 patient records and identified 31 patients with FNP due to benign TBMs. Moderate FNP (HB Grades II-IV) was dominant for facial nerve schwannoma (FNS) (n=15), whereas severe FNP (Grades V and VI) was dominant for cholesteatomas (n=8) and hemangiomas (n=3). The average ENoG value was 19.8% for FNS, 15.6% for cholesteatoma, and 0% for hemangioma. Analysis of the correlation between HB grade and ENoG value for FNP due to TBMs and Bell's palsy revealed that given the same ENoG value, the corresponding HB grade was better for FNS, followed by cholesteatoma, and worst in Bell's palsy. Facial nerve damage caused by benign TBMs could depend on the underlying pathology. Facial movement and ENoG values did not correlate when comparing TBMs and Bell's palsy. When the HB grade is found to be unexpectedly better than the ENoG value, TBMs should be included in the differential diagnosis. Copyright © 2017 Elsevier B.V. All rights reserved.

Bell's palsy is a kind of peripheral neural disease that cause abrupt onset of unilateral facial weakness. In the pathologic study, it was evidenced that ischemia of facial nerve at the affected side of face existed in Bell's palsy patients. Since the direction of facial nerve blood flow is primarily proximal to distal, facial skin microcirculation would also be affected after the onset of Bell's palsy. Therefore, monitoring the full area of facial skin microcirculation would help to identify the condition of Bell's palsy patients. In this study, a non-invasive, real time and full field imaging technology - laser speckle imaging (LSI) technology was applied for measuring facial skin blood perfusion distribution of Bell's palsy patients. 85 participants with different stage of Bell's palsy were included. Results showed that Bell's palsy patients' facial skin perfusion of affected side was lower than that of the normal side at the region of eyelid, and that the asymmetric distribution of the facial skin perfusion between two sides of eyelid is positively related to the stage of the disease (P Bell's palsy patients, and we discovered that the facial skin blood perfusion could reflect the stage of Bell's palsy, which suggested that microcirculation should be investigated in patients with this neurological deficit. It was also suggested LSI as potential diagnostic tool for Bell's palsy.

Full Text Available BACKGROUND The facial nerve paralysis is a broad term having so many differential diagnoses starting from congenital causes to malignant tumour. Accurate diagnosis with localisation of the site of injury or compression and timely intervention has become a challenge to an otorhinolaryngologist. Objective- To outline the incidence of the different aetiologies and the profile of peripheral facial nerve paralysis patients in the Otolaryngology Dept. of ENT in VIMSAR, Burla. MATERIALS AND METHODS The records of 53 patients with facial nerve paralysis seen during the years of 2016 & 2017 were analysed. RESULTS From the 53 patients analysed, 60.4% were male, maximum cases 35.85% were in 3 rd decade of age and had the right side of the face involved in 62.26%. Bell´s palsy was the most frequent aetiology (66.04%, others are traumatic (11.32%, Ramsay Hunt syndrome (1.89%, CSOM (16.98%, malignant otitis externa (1.89%. One case of Bell´s palsy during pregnancy was also seen in this series. CONCLUSION The data found are similar to the most of the literature showing that Bell´s palsy is still the most frequent. Males are more commonly affected with a preponderance to involve right side of face.

To describe the surgical management and convalescence of two patients presenting with severe facial nerve weakness associated with small intracanalicular vestibular schwannomas (VS). Retrospective review. Two adult female patients presenting with audiovestibular symptoms and subacute facial nerve paralysis (House-Brackmann Grade IV and V). In both cases, post-contrast T1-weighted magnetic resonance imaging revealed an enhancing lesion within the internal auditory canal without lateral extension beyond the fundus. Translabyrinthine exploration demonstrated vestibular nerve origin of tumor, extrinsic to the facial nerve, and frozen section pathology confirmed schwannoma. Gross total tumor resection with VIIth cranial nerve preservation and decompression of the labyrinthine segment of the facial nerve was performed. Both patients recovered full motor function between 6 and 8 months after surgery. Although rare, small VS may cause severe facial neuropathy, mimicking the presentation of facial nerve schwannomas and other less common pathologies. In the absence of labyrinthine extension on MRI, surgical exploration is the only reliable means of establishing a diagnosis. In the case of confirmed VS, early gross total resection with facial nerve preservation and labyrinthine segment decompression may afford full motor recovery-an outcome that cannot be achieved with facial nerve grafting.

The history of facial palsy and spasm

Although Sir Charles Bell was the first to provide the anatomic basis for the condition that bears his name, in recent years researchers have shown that other European physicians provided earlier clinical descriptions of peripheral cranial nerve 7 palsy. In this article, we describe the history of facial distortion by Greek, Roman, and Persian physicians, culminating in Razi's detailed description in al-Hawi. Razi distinguished facial muscle spasm from paralysis, distinguished central from peripheral lesions, gave the earliest description of loss of forehead wrinkling, and gave the earliest known description of bilateral facial palsy. In doing so, he accurately described the clinical hallmarks of a condition that we recognize as Bell palsy. PMID:21747074

Tabachnikova, T V; Serova, N K; Shimansky, V N

2014-01-01

Over 200 patients with acoustic neuromas and over 100 patients with posterior cranial fossa meningiomas are annually operated on at the N.N. Burdenko Neurosurgical Institute. Intraoperative monitoring of the facial nerve function is used in most patients with tumors of the posterior cranial fossa to identify the facial nerve in the surgical wound. If the anatomical integrity of the facial nerve in the cranial cavity cannot be retained, facial nerve repair is performed to restore the facial muscle function. Intraoperative electrical stimulation of the facial nerve has a great prognostic significance to evaluate the dynamics of lagophthalmos in the late postoperative period and to select the proper method for lagophthalmos correction. When the facial nerve was reinnervated by the descending branch or trunk of the hypoglossal nerve, sufficient eyelid closure was observed only in 3 patients out of 17.

Bell's palsy in known as the most common cause of facial paralysis, determined by the acute onset of lower motor neuron weakness of the facial nerve with no detectable cause. With a lifetime risk of 1 in 60 and an annual incidence of 11-40/100,000 population, the condition resolves completely in around 71% of the untreated cases. Clinical trials performed for Bell's palsy have reported some recurrences, ipsilateral or contralateral to the side affected in the primary episode of facial palsy. Only few data are found in the literature. Melkersson-Rosenthal is a rare neuromucocutaneous syndrome characterized by recurrent facial paralysis, fissured tongue (lingua plicata), orofacial edema. We attempted to analyze some clinical and epidemiologic aspects of recurrent idiopathic palsy, and to develop relevant correlations between the existing data in literature and those obtained in this study. This is a retrospective study carried out on a 10-years period for adults and a five-year period for children. A number of 185 patients aged between 4 and 70 years old were analyzed. 136 of them were adults and 49 were children. 22 of 185 patients with Bell's palsy (12%) had a recurrent partial or complete facial paralysis with one to six episodes of palsy. From this group of 22 cases, 5 patients were diagnosed with Melkersson-Rosenthal syndrome. The patients' age was between 4 and 70 years old, with a medium age of 27,6 years. In the group studied, fifteen patients, meaning 68%, were women and seven were men. The majority of patients in our group with more than two facial palsy episodes had at least one episode on the contralateral side. Our study found a significant incidence of recurrences of idiopathic facial palsy. Recurrent idiopathic facial palsy and Melkersson-Rosenthal syndrome is diagnosed more often in young females. Recurrence is more likely to occur in the first two years from the onset, which leads to the conclusion that we should have a follow up of patients

Data on incidence of facial palsy is generally lacking in Nigeria. To assess six years' incidence of facial palsy in Murtala Muhammed Specialist Hospital (MMSH), Kano, Nigeria. The records of patients diagnosed as facial problems between January 2000 and December 2005 were scrutinized. Data on diagnosis, age, sex, side affected, occupation and causes were obtained. A total number of 698 patients with facial problems were recorded. Five hundred and ninety four (85%) were diagnosed as facial palsy. Out of the diagnosed facial palsy, males (56.2%) had a higher incidence than females; 20-34 years age group (40.3%) had a greater prevalence; the commonest cause of facial palsy was found out to be Idiopathic (39.1%) and was most common among business men (31.6%). Right sided facial palsy (52.2%) was predominant. Incidence of facial palsy was highest in 2003 (25.3%) and decreased from 2004. It was concluded that the incidence of facial palsy was high and Bell's palsy remains the most common causes of facial (nerve) paralysis.

Magnetic resonance imaging (MRI) was carried out in 27 patients with Bell's palsy. T1-weighted spin-echo images (TR500/TE25-34) were taken before and after the intravenous administration of Gd-DTPA (0.1 mmol/kg) with 0.5T superconductive MRI. There was significant enhancement at the geniculate ganglion and the horizontal segment of the involved facial nerve in 22 patients (81.5%) and at the vertical segment in 20 (74.1%). Enhancement at the meatal fundus was seen in only 4 patients (14.9%) and at the labyrinthine segment in 8 (29.6%). These results corroborate other evidence that the geniculate ganglion is involved most frequently in Bell's palsy. In addition, the enhancement of the proximal portion, i.e. the meatal fundus and the labyrinthine segment of the nerve, although not common, noted in this study may be important in the diagnosis and treatment of Bell's palsy.

The masseteric nerve has many advantages including low morbidity, its proximity to the facial nerve, the strong motor impulse, its reliability, and the fast reinnervation that is achievable in most patients. Reinnervation of a neuromuscular transplant is the main indication for its use, but it has been used for the treatment of recent facial palsies with satisfactory results. We have retrospectively evaluated 60 patients who had facial animation procedures using the masseteric nerve during the last 10 years. The patients included those with recent, and established or congenital, unilateral and bilateral palsies. The masseteric nerve was used for coaptation of the facial nerve either alone or in association with crossfacial nerve grafting, or for the reinnervation of gracilis neuromuscular transplants. Reinnervation was successful in all cases, the mean (range) time being 4 (2-5) months for facial nerve coaptation and 4 (3-7) months for neuromuscular transplants. Cosmesis was evaluated (moderate, n=10, good, n=30, and excellent, n=20) as was functional outcome (no case of impairment of masticatory function, all patients able to smile, and achievement of a smile independent from biting). The masseteric nerve has many uses, including in both recent, and established or congenital, cases. In some conditions it is the first line of treatment. The combination of combined techniques gives excellent results in unilateral palsies and should therefore be considered a valid option.

To determine the value of blink reflex in early diagnosis and prognosis evaluation of Bell palsy. Blink reflex and facial nerve conduction were examined in 58 patients with Bell palsy within one week after symptom onset. The patients without response of R1 , R2 and R2 ' waves were classified as complete efferent retardarce (Group A, 30 cases), and those with response of R1 , R2 and R2 ' waves were classified as incomplete efferent anomalies (Group B, 28 cases). The clinical outcomes after three months of systemic therapy were evaluated using the House-Blackmann (H-B) scale. Efferent anomalies of blink reflex occurred in ail of the 58 patients. Abnormal results of facial nerve conduction appeared in 23 (39. 7%) patients. The three months therapy was effective in 93% patients in Group B and 70% patients in Group A (PBell palsy.

Automated eye movement tracking may provide clues to nervous system function at many levels. Spatial calibration of the eye tracking device requires the subject to have relatively intact ocular motility that implies function of cranial nerves (CNs) III (oculomotor), IV (trochlear), and VI (abducent) and their associated nuclei, along with the multiple regions of the brain imparting cognition and volition. The authors have developed a technique for eye tracking that uses temporal rather than spatial calibration, enabling detection of impaired ability to move the pupil relative to normal (neurologically healthy) control volunteers. This work was performed to demonstrate that this technique may detect CN palsies related to brain compression and to provide insight into how the technique may be of value for evaluating neuropathological conditions associated with CN palsy, such as hydrocephalus or acute mass effect. The authors recorded subjects' eye movements by using an Eyelink 1000 eye tracker sampling at 500 Hz over 200 seconds while the subject viewed a music video playing inside an aperture on a computer monitor. The aperture moved in a rectangular pattern over a fixed time period. This technique was used to assess ocular motility in 157 neurologically healthy control subjects and 12 patients with either clinical CN III or VI palsy confirmed by neuro-ophthalmological examination, or surgically treatable pathological conditions potentially impacting these nerves. The authors compared the ratio of vertical to horizontal eye movement (height/width defined as aspect ratio) in normal and test subjects. In 157 normal controls, the aspect ratio (height/width) for the left eye had a mean value ± SD of 1.0117 ± 0.0706. For the right eye, the aspect ratio had a mean of 1.0077 ± 0.0679 in these 157 subjects. There was no difference between sexes or ages. A patient with known CN VI palsy had a significantly increased aspect ratio (1.39), whereas 2 patients with known CN III

To determine the plasma fibrinogen level in patients with Bell palsy and explore the significances of it in Bell palsy. One hundred five consecutive patients with facial paralysis were divided into 3 groups: group I (Bell palsy), group II (temporal bone fractures), and group III (facial nerve schwannoma). In addition, 22 volunteers were defined as control group. Two milliliters fasting venous blood from elbow was collected, and was evaluated by CA-7000 Full-Automatic Coagulation Analyzer. The plasma fibrinogen concentration was significantly higher in the group of patients with Bell palsy (HB IV-VI) than that in the control group (P 0.05); similarly, there was also no marked difference between group III and control group (P >0.05). In group I, the plasma fibrinogen levels became higher with the HB grading increase. The plasma fibrinogen level of HB-VI was highest. Plasma fibrinogen has an important clinical meaning in Bell palsy, which should be used as routine examination items. Defibrinogen in treatment for patients with high plasma fibrinogen content also should be suggested.

To evaluate the MRI findings of acute facial nerve paralysis in Bell's palsy and herpes zoster opticus, and to correlate these with the clinical findings. We retrowspectively reviewed the MRI findings in six cases of BEll's palsy(BP) and two of herpes zoster oticus(HZO), and compared them with the findings for 30 normal facial nerves. This nerve was considered abnormal when its signal intensity was greater than that of brain parenchyma or the contralateral normal side on Gd-enhanced T1-weighted axial and coronal MR images. We analysed the location and degree of contrast enhancement, interval change, and clinical progression in correlation with House-Brackmann(HB) grade and electroneuronography (ENoG) findings. Fifteen of 30 normal facial nerves(50%) seen on Gd-enhanced MRI were mildly enhanced in the geniculate ganglion, the proximal tympanic, and the proximal mastoid segment of the facial nerve. No enhancement of the internal auditory canal(IAC) or labyrinthine segment of the facial nerve was noted, however. In BP and HZO, Gd-enhanced MR images revealed fair to marked enhancement for more than two segments from the internal auditory canal to the mastoid segment of the facial nerve. During follow-up MRI, enhancement of the facial nerve varied in location and signal intensity, though gradually decreased in intensity approximately eight weeks after the onset of facial nerve palsy. No correlation between clinical HB grade, ENoG, and follow up MRI findings was noted. Except in the internal auditory canal and labyrinthine segment, normal facial nevemay show mild and relatively symmetrical enhancement. In BP and HZO, the facial nerve showed diffuse enhancement from the IAC to the mastoid segment.=20.

Descriptions of the anatomy of the neural communications among the cranial nerves and their branches is lacking in the literature. Knowledge of the possible neural interconnections found among these nerves may prove useful to surgeons who operate in these regions to avoid inadvertent traction or transection. We review the literature regarding the anatomy, function, and clinical implications of the complex neural networks formed by interconnections among the lower cranial and upper cervical nerves. A review of germane anatomic and clinical literature was performed. The review is organized in two parts. Part I concerns the anastomoses between the trigeminal, facial, and vestibulocochlear nerves or their branches with any other nerve trunk or branch in the vicinity. Part II concerns the anastomoses among the glossopharyngeal, vagus, accessory and hypoglossal nerves and their branches or among these nerves and the first four cervical spinal nerves; the contribution of the autonomic nervous system to these neural plexuses is also briefly reviewed. Part I is presented in this article. An extensive anastomotic network exists among the lower cranial nerves. Knowledge of such neural intercommunications is important in diagnosing and treating patients with pathology of the skull base. Copyright © 2013 Wiley Periodicals, Inc.

2009-08-01

Facial synkinesis (or synkinesia) (FS) occurs frequently after paresis or paralysis of the facial nerve and is in most cases due to aberrant regeneration of (branches of) the facial nerve. Patients suffer from inappropriate and involuntary synchronous facial muscle contractions. Here we describe two cases of sound-induced facial synkinesis (SFS) after facial nerve injury. As far as we know, this phenomenon has not been described in the English literature before. Patient A presented with right hemifacial palsy after lesion of the facial nerve due to skull base fracture. He reported involuntary muscle activity at the right corner of the mouth, specifically on hearing ringing keys. Patient B suffered from left hemifacial palsy following otitis media and developed involuntary muscle contraction in the facial musculature specifically on hearing clapping hands or a trumpet sound. Both patients were evaluated by means of video, audio and EMG analysis. Possible mechanisms in the pathophysiology of SFS are postulated and therapeutic options are discussed.

Left is right and right is wrong: fluorodeoxyglucose uptake in left hemi-diaphragm due to right phrenic nerve palsy

A 36-year-old Indian man, a recently diagnosed case of the right lung carcinoma underwent fluorodeoxyglucose positron emission tomography-computed tomography (FDG PET/CT) for staging of the malignancy. PET/CT showed increased FDG uptake in the right lung mass, consistent with the known primary tumor. Right hemidiaphragm was found to be elevated on CT, suggesting right diaphragmatic paresis. The PET scan demonstrated asymmetric, intense FDG uptake in the left hemidiaphragm and accessory muscles of respiration, which was possibly due to compensatory increased workload related to contralateral right diaphragmatic paresis. The right diaphragmatic paresis was hypothesized to be caused by phrenic nerve palsy by right lung neoplasm. (author)

Bell palsy is a facial nerve neuropathy that is a rare disorder but occurs at higher frequency in pregnancy. Almost 30% of cases are associated with preeclampsia or gestational hypertension. Bilateral Bell palsy occurs in only 0.3%-2.0% of cases of facial paralysis, has a poorer prognosis for recovery, and may be associated with a systemic disorder. We describe a case of a 24-year-old primigravid woman with a twin gestation at 35 weeks diagnosed initially with bilateral facial palsy and subsequently with preeclampsia. She then developed partial hemolysis, elevated liver enzymes, and low platelet count syndrome, prompting the diagnosis of severe preeclampsia, and was delivered. Bilateral facial palsy is a rare entity in pregnancy that may be the first sign of preeclampsia and suggests increased severity of disease, warranting close monitoring.

A general practice approach to Bell's palsy.

Bell's palsy is characterised by an acute onset of unilateral, lower motor neuron weakness of the facial nerve in the absence of an identifiable cause. Establishing the correct diagnosis is imperative and choosing the correct treatment options can optimise the likelihood of recovery. This article summarises our understanding of Bell's palsy and the evidence-based management options available for adult patients. The basic assessment should include a thorough history and physical examination as the diagnosis of Bell's palsy is based on exclusion. For confirmed cases of Bell's palsy, corticosteroids are the mainstay of treatment and should be initiated within 72 hours of symptom onset. Antiviral therapy in combination with corticosteroid therapy may confer a small benefit and may be offered on the basis of shared decision making. Currently, no recommendations can be made for acupuncture, physical therapy, electrotherapy or surgical decompression because well-designed studies are lacking and available data are of low quality.

Painful tic convulsif is referred to as the concurrent trigeminal neuralgia and hemifacial spasm. However, painful tic convulsif after ipsilateral Bell palsy has never been reported before. We report a case of a 77-year-old woman with coexistent trigeminal neuralgia and hemifacial spasm who had experienced Bell palsy half a year ago. The patient underwent microvascular decompression. Intraoperatively, the vertebrobasilar artery was found to deviate to the symptomatic side and a severe adhesion was observed in the cerebellopontine angle. Meanwhile, an ectatic anterior inferior cerebellar artery and 2 branches of the superior cerebellar artery were identified to compress the caudal root entry zone (REZ) of the VII nerve and the rostroventral cisternal portion of the V nerve, respectively. Postoperatively, the symptoms of spasm ceased immediately and the pain disappeared within 3 months. In this article, the pathogenesis of the patient's illness was discussed and it was assumed that the adhesions developed from inflammatory reactions after Bell palsy and the anatomic features of the patient were the factors that generated the disorder. Microvascular decompression surgery is the suggested treatment of the disease, and the dissection should be started from the caudal cranial nerves while performing the operation.

Complete 3rd cranial nerve dysfunction postdeflation/ excision of an encasing pituitary macroadenoma intrasellular cyst: A Case Report

Directory of Open Access Journals (Sweden)

Ng C. S.

2016-09-01

Full Text Available Central nervous system injury in particular cranial nerve palsy has been reported to be as high as 2%. Such prevalence of palsy generally attributed to surgical manipulation at the cavernous sinus, especially incurring the abducens nerve. We report the first case of acute oculomotor nerve sequel to the release of cystic fluid wrapping the nerve following a transsphenoidal excision of pituitary macroadenoma in a 57-year-old woman. She attended with the presentation of acute excruciating headache associated with partial drooping of right eye. The computed tomography and magnetic resonance imaging (MRI were consistent with pituitary apoplexy of an underlying pituitary macroadenoma. Urgent transsphenoidal hypophysectomy was done. Intra-operatively, cystic fluid was aspirated during pituitary tumour dissection. At the same time, curettage was employed to removal residual tumour after the tumour biopsy. Immediate post-operative assessment noted complete right eye ptosis, with clinical evidence of complete right third and fourth nerve palsies. MRI was repeated a week later in view of such palsy non-resolution. However, no local compression or edema noted. Observation and monitoring were opted versus surgical revision. Propitiously the aforementioned cranial nerve palsies persist for a month and subsequently subsided. In this case, we highlight the potential deleterious impact of aspirating cystic component and curettaging during pituitary surgery. Likely postulated accounts for such occurrence include sudden release of fluid pressure with resultant cystic traction on its enfolding cranial nerves and subsequent neuropraxia. We aim to invite comments that could enlighten us on this gray area.

Facial nerve disorders may be of sudden onset and more often of unknown etiology. Edema of the facial nerve within the fallopian canal results in Bell's palsy. This causes compression of the nerve and affects the microcirculation. Many authors have suggested treatment for facial nerve paralysis ranging from simple physiotherapy to complicated microvascular decompression. It more often results in symptoms like synkinesis and muscle spasm after the decompression surgery of the nerve because of the inability to arrange the nerve fibers within the canal. The treatment choice also depends on patient's age, extent of the nerve damage, and patient's needs and desires. Many patients who cannot be rehabilitated functionally can be treated for esthetics of the involved muscles. This case report elaborates about a patient who was rehabilitated for esthetics and to some extent for function.

Submandibular gland function and parotid gland function in Bell's palsy, 3

1986-01-01

With the use of sup(99m)Tc, we attempted to measure simultaneously submandibular gland function and parotid gland function, which is thought not to be controlled by the facial nerve, in patients with unilateral Bell's palsy. For comparison, the lachrymal gland function of some patients was measured by the thread method. We found that facial palsy sometimes affects parotid gland function as well as submandibular gland function. In 60 % of the patients the function of the two glands tended to be affected in the same way. Lachrymal gland function tended to be affected in a similar way to parotid gland function. We conclude that the chorda tympani and the greater petrosal nerve may influence parotid gland function. (author)

An unusual presentation of whiplash injury: long thoracic and spinal accessory nerve injury

Whiplash injuries from motor vehicle accidents are very common. The usual presentation and course of this condition normally results in resolution of symptoms within a few weeks. Brachial plexus traction injuries without any bone or joint lesion of the cervical spine have been reported before. We report a case where a gentleman was involved in a rear end vehicle collision, sustained a whiplash injury and was later found to have a long thoracic nerve palsy and spinal accessory nerve palsy. Although isolated injuries of both nerves following a whiplash injury have been reported, combined injury of the two nerves following a whiplash injury is very uncommon and is being reported for the first time.

A 66-year-old male was admitted to our neurosurgical floor because of double vision and gait disturbance. Neurological examinations revealed bilateral 6th nerve palsy with both eyes pointing toward the midline. Initially, using a tentative diagnosis of intracranial mass lesions, especially localized at the base of the skull, computerized tomography of the head, cerebral angiography, orbital venography, and metrizamide CT cisternography were performed; the findings were normal. An orbital CT scan showed an enlargement of the bilateral medial rectus muscles, and the thyroid functions of T 3 and T 4 and the T 3 uptake were all elevated, which was compatible with the diagnosis of Graves' disease. The limitations of both eyeballs were considered to be due not to the 6th nerve palsy, but to the hypertrophy of the bilateral medial rectus muscles. We neurosurgeons should recall Graves' disease as well as intracranial lesions, cerebrovascular disease, and post-traumatic sequelae when examining a patient who presents limitations of external ocular movement.

Ramus marginalis mandibulae nervus facialis palsy in hemifacial microsomia.

Silvestri, A; Mariani, G; Vernucci, R A

2008-12-01

The paralysis of the ramus marginalis mandibulae nervus facialis may occur in Hemifacial Microsomia (HM); the combination of both HM and palsy contributes to an elongation of the mandibular body. This study explores a possible correlation between neurological deficit, muscular atony, and structural deficiency. Of 58 patients with HM who had come to the University of Rome (Sapienza) Pre-surgical Orthodontics Unit, 4 patients were afflicted with Hemifacial Microsomia and ramus marginalis mandibulae nervus palsy; these patients underwent physical, neurological, opthamologic and systemic examinations. The results were then analysed in order to determine a possible correlation between neuro-muscular and structural deficit. Electroneurographic and electromyographic examinations were performed to estimate facial nerve and muscles involvement. Neuroelectrographic exam showed a damage of the nervous motor fibres of the facial nerve ipsilateral to HM, with an associated damage of the muscular function, while neuro-muscular functions on the healthy side were normal. The peripheral nervous and muscular deficits affect the function of facial soft tissues and the growth of mandibular body with an asymmetry characterised by a hypodevelopment of the ramus (due to the HM) and by an elongation of the mandibular body (due to ramus marginalis mandibulae nerve palsy), so that the chin deviation is contralateral to HM. In these forms, a neurological examination is necessary to assess the neurological damage on the HM side. Neuromuscular deficiency can also contribute to a relapse tendency after a surgical-orthodontic treatment.

Vascular endothelial growth factor gene therapy improves nerve regeneration in a model of obstetric brachial plexus palsy.

2015-03-01

The treatment of obstetric brachial plexus palsy has been limited to conservative therapies and surgical reconstruction of peripheral nerves. In addition to the damage of the brachial plexus itself, it also leads to a loss of the corresponding motoneurons in the spinal cord, which raises the need for supportive strategies that take the participation of the central nervous system into account. Based on the protective and regenerative effects of VEGF on neural tissue, our aim was to analyse the effect on nerve regeneration by adenoviral gene transfer of vascular endothelial growth factor (VEGF) in postpartum nerve injury of the brachial plexus in rats. In the present study, we induced a selective crush injury to the left spinal roots C5 and C6 in 18 rats within 24 hours after birth and examined the effect of VEGF-gene therapy on nerve regeneration. For gene transduction an adenoviral vector encoding for VEGF165 (AdCMV.VEGF165) was used. In a period of 11 weeks, starting 3 weeks post-operatively, functional regeneration was assessed weekly by behavioural analysis and force measurement of the upper limb. Morphometric evaluation was carried out 8 months post-operatively and consisted of a histological examination of the deltoid muscle and the brachial plexus according to defined criteria of degeneration. In addition, atrophy of the deltoid muscle was evaluated by weight determination comparing the left with the right side. VEGF expression in the brachial plexus was quantified by an enzyme-linked immunosorbent assay (ELISA). Furthermore the motoneurons of the spinal cord segment C5 were counted comparing the left with the right side. On the functional level, VEGF-treated animals showed faster nerve regeneration. It was found less degeneration and smaller mass reduction of the deltoid muscle in VEGF-treated animals. We observed significantly less degeneration of the brachial plexus and a greater number of surviving motoneurons (P reason for these effects. The clinical use

Development and Functional Organization of the Cranial Nerves in Lampreys.

Pombal, Manuel A; Megías, Manuel

2018-04-16

Lampreys, together with hagfishes, are the only extant representatives of the oldest branch of vertebrates, the agnathans, which are the sister group of gnathostomes; therefore, studies on these animals are of great evolutionary significance. Lampreys exhibit a particular life cycle with remarkable changes in their behavior, concomitant, in part, with important modifications in the head and its musculature, which might influence the development of the cranial nerves. In this context, some cranial nerves such as the optic nerve and the ocular motor nerves, which develop slowly during an extremely long larval period lasting more than five years, have been more thoroughly investigated; however, much less experimental information is available about others, such as the facial or the hypoglossal nerves. In addition, the possible existence of a "true" accessory nerve in these animals is still a matter of conjecture. Although growing in last decades, investigations on the physiology of the lamprey cranial nerves is scanty. This review focuses on past and recent findings that have contributed to characterize the anatomical organization of the cranial nerves in lampreys, including their components and nuclei, and their relations in the brain; in addition, comments on their development and functional role are also included.

Introduction: Schwannomas of the 6th nerve are extremely rare.Only 22 cases of intracranial schwannomas of the 6th cranial nerve pathologically confirmed have been reported.Case Presentation: Here, we report a case of a 14-year-old girl who presented with isolated progressive 6th nerve palsy.A cisternal type of schwannomawas found from neuro-imaging.Subtotal removal of the tumor was performed by a routine left subtemporal craniotomy with an petrosectomy.The attachment to the 6th nerve was found.After surgery, the patient's 6th nerve palsy remained.Histological images revealed a cellular schwannoma.Then the classification, clinical presentation, diagnosis, operation, stereotactic radiosurgery are reviewed.Conclusions: The location and the attachment to the 6th nerve is the key for diagnosis.Most cases are treated surgically.It looks like it is not easy to completely remove for CA type because of invasion of the cavernous sinus or firm adherence to the nerves.The 6th nerve function seldom completely recovered postoperatively.The direction of further research is to improve the diagnosis and therapy to have better nerve recovery.

Full Text Available Hypoglossal (XII motoneurons innervate tongue muscles and are vital for maintaining upper-airway patency during inspiration. Depression of XII nerve activity by opioid analgesics is a significant clinical problem, but underlying mechanisms are poorly understood. Currently there are no suitable pharmacological approaches to counter opiate-induced suppression of XII nerve activity while maintaining analgesia. Ampakines accentuate alpha-amino-3-hydroxyl-5-methyl-4-isoxazole-propionate (AMPA receptor responses. The AMPA family of glutamate receptors mediate excitatory transmission to XII motoneurons. Therefore the objectives were to determine whether the depressant actions of mu-opioid receptor activation on inspiratory activity includes a direct inhibitory action at the inspiratory premotoneuron to XII motoneuron synapse, and to identify underlying mechanism(s. We then examined whether ampakines counteract opioid-induced depression of XII motoneuron activity.A medullary slice preparation from neonatal rat that produces inspiratory-related output in vitro was used. Measurements of inspiratory burst amplitude and frequency were made from XII nerve roots. Whole-cell patch recordings from XII motoneurons were used to measure membrane currents and synaptic events. Application of the mu-opioid receptor agonist, DAMGO, to the XII nucleus depressed the output of inspiratory XII motoneurons via presynaptic inhibition of excitatory glutamatergic transmission. Ampakines (CX614 and CX717 alleviated DAMGO-induced depression of XII MN activity through postsynaptic actions on XII motoneurons.The inspiratory-depressant actions of opioid analgesics include presynaptic inhibition of XII motoneuron output. Ampakines counteract mu-opioid receptor-mediated depression of XII motoneuron inspiratory activity. These results suggest that ampakines may be beneficial in countering opiate-induced suppression of XII motoneuron activity and resultant impairment of airway patency.

Detailed imaging of the five sections of the full intratemporal course of the facial nerve can be achieved by MRI and using thin tomographic section techniques and surface coils. Contrast media are required for tomographic imaging of pathological processes. Established methods are available for diagnostic evaluation of cerebellopontine angle tumors and chronic Bell's palsy, as well as hemifacial spasms. A method still under discussion is MRI for diagnostic evaluation of Bell's palsy in the presence of fractures of the petrous bone, when blood volumes in the petrous bone make evaluation even more difficult. MRI-based diagnostic evaluation of the idiopatic facial paralysis currently is subject to change. Its usual application cannot be recommended for routine evaluation at present. However, a quantitative analysis of contrast medium uptake of the nerve may be an approach to improve the prognostic value of MRI in acute phases of Bell's palsy. (orig./CB) [de

OBJECTIVE Neonatal brachial plexus palsy (NBPP) continues to be a problematic occurrence impacting approximately 1.5 per 1000 live births in the United States, with 10%-40% of these infants experiencing permanent disability. These children lose elbow flexion, and one surgical option for recovering it is the Oberlin transfer. Published data support the use of the ulnar nerve fascicle that innervates the flexor carpi ulnaris as the donor nerve in adults, but no analogous published data exist for infants. This study investigated the association of ulnar nerve fascicle choice with functional elbow flexion outcome in NBPP. METHODS The authors conducted a retrospective study of 13 cases in which infants underwent ulnar to musculocutaneous nerve transfer for NBPP at a single institution. They collected data on patient demographics, clinical characteristics, active range of motion (AROM), and intraoperative neuromonitoring (IONM) (using 4 ulnar nerve index muscles). Standard statistical analysis compared pre- and postoperative motor function improvement between specific fascicle transfer (1-2 muscles for either wrist flexion or hand intrinsics) and nonspecific fascicle transfer (> 2 muscles for wrist flexion and hand intrinsics) groups. RESULTS The patients' average age at initial clinic visit was 2.9 months, and their average age at surgical intervention was 7.4 months. All NBPPs were unilateral; the majority of patients were female (61%), were Caucasian (69%), had right-sided NBPP (61%), and had Narakas grade I or II injuries (54%). IONM recordings for the fascicular dissection revealed a donor fascicle with nonspecific innervation in 6 (46%) infants and specific innervation in the remaining 7 (54%) patients. At 6-month follow-up, the AROM improvement in elbow flexion in adduction was 38° in the specific fascicle transfer group versus 36° in the nonspecific fascicle transfer group, with no statistically significant difference (p = 0.93). CONCLUSIONS Both specific and

OBJECT Unruptured posterior communicating artery (PCoA) aneurysms with oculomotor nerve palsy (ONP) have a very high risk of rupture. This study investigated the hemodynamic and morphological characteristics of intracranial aneurysms with high rupture risk by analyzing PCoA aneurysms with ONP. METHODS Fourteen unruptured PCoA aneurysms with ONP, 33 ruptured PCoA aneurysms, and 21 asymptomatic unruptured PCoA aneurysms were included in this study. The clinical, morphological, and hemodynamic characteristics were compared among the different groups. RESULTS The clinical characteristics did not differ among the 3 groups (p > 0.05), whereas the morphological and hemodynamic analyses showed that size, aspect ratio, size ratio, undulation index, nonsphericity index, ellipticity index, normalized wall shear stress (WSS), and percentage of low WSS area differed significantly (p PCoA aneurysms with ONP demonstrated a distinctive morphological-hemodynamic pattern that was significantly different compared with asymptomatic unruptured PCoA aneurysms and was similar to ruptured PCoA aneurysms. The larger size, more irregular shape, and lower WSS might be related to the high rupture risk of PCoA aneurysms.

Imaging plays a critical role in the evaluation of a number of facial nerve disorders. The facial nerve has a complex anatomical course; thus, a thorough understanding of the course of the facial nerve is essential to localize the sites of pathology. Facial nerve dysfunction can occur from a variety of causes, which can often be identified on imaging. Computed tomography and magnetic resonance imaging are helpful for identifying bony facial canal and soft tissue abnormalities, respectively. Ultrasound of the facial nerve has been used to predict functional outcomes in patients with Bell’s palsy. More recently, diffusion tensor tractography has appeared as a new modality which allows three-dimensional display of facial nerve fibers

Objective: To study the influence of 125 I seed interstitial brachytherapy in parotid region on the recovery of facial nerve function. Methods: A total of the data of 21 patients with primary parotid carcinoma were treated with resection and 125 I interstitial brachytherapy. All the patients had no facial palsy before operation and the prescribed dose was 60 Gy. During 4 years of follow-up, the House-Brackmann grading scales and ENoG were used to evaluate the function of facial nerve. According to the modified regional House-Brackmann grading scales, the facial nerve branches of patients in affected side were divided into normal and abnormal groups, and were compared with those in contra-lateral side. Results: Post-operation facial palsy occurred in all the patients, but the facial palsy recovered within 6 months. The latency time differences between affected side and contralateral side were statistically significant in abnormal group from 1 week to 6 months after treatment (t=2.362, P=0.028), and were also different in normal group 1 week after treatment (t=2.522, P=0.027). Conclusions: 125 I interstitital brachytherapy has no influence on recovery of facial nerve function after tumor resection and no delayed facial nerve damage. (authors)

Autism is often associated with multiple developmental anomalies including asymmetric facial palsy. In order to establish the etiology of autism with facial palsy, research into developmental abnormalities of the peripheral facial nerves is necessary. In the present study, to investigate the development of peripheral cranial nerves for use in an animal model of autism, rat embryos were treated with valproic acid (VPA) in utero and their cranial nerves were visualized by immunostaining. Treatment with VPA after embryonic day 9 had a significant effect on the peripheral fibers of several cranial nerves. Following VPA treatment, immunoreactivity within the trigeminal, facial, glossopharyngeal and vagus nerves was significantly reduced. Additionally, abnormal axonal pathways were observed in the peripheral facial nerves. Thus, the morphology of several cranial nerves, including the facial nerve, can be affected by prenatal VPA exposure as early as E13. Our findings indicate that disruption of early facial nerve development is involved in the etiology of asymmetric facial palsy, and may suggest a link to the etiology of autism.

Peripheral facial nerve paralysis in children might be an alarming sign of serious disease such as malignancy, systemic disease, congenital anomalies, trauma, infection, middle ear surgery, and hypertension. The cases of 40 consecutive children and adolescents who were diagnosed with peripheral facial nerve paralysis at Baskent University Adana Hospital Pediatrics and Pediatric Neurology Unit between January 2010 and January 2013 were retrospectively evaluated. We determined that the most common cause was Bell palsy, followed by infection, tumor lesion, and suspected chemotherapy toxicity. We noted that younger patients had generally poorer outcome than older patients regardless of disease etiology. Peripheral facial nerve paralysis has been reported in many countries in America and Europe; however, knowledge about its clinical features, microbiology, neuroimaging, and treatment in Turkey is incomplete. The present study demonstrated that Bell palsy and infection were the most common etiologies of peripheral facial nerve paralysis. © The Author(s) 2014.

Our objective was to assess the prognostic value of measurements of the degree of contrast enhancement of the intratemporal segments of the facial nerve. We prospectively obtained MRI, slice thickness <1 mm of 20 patients with a facial palsy on the first day of inpatient treatment, and measured contrast enhancement of the nerve. The data were compared with compound muscle action potential (CMAP) measurements and the clinical course. Analysis of the initial enabled differentiation of three patients whose palsy was to show no improvement from 17 whose palsy was to resolve as expected. No patient with a poor outcome showed lesser increase in signal in the internal auditory canal, pars tympanica and pars mastoidea than patients who fully recovered. In no patient who had been diagnosed on the basis of the initial MRI as having a ''normal'' palsy was the amplitude of the (CMAP) reduced to less than 20% that of the normal side. Measurement of contrast enhancement was thus shown to be a prognostic indicator and may provide a basis for a differential treatment of facial palsy. (orig.)

Pathology and surgery of bell's palsy: A report of 108 cases subjected to the ballance-duel operation

Directory of Open Access Journals (Sweden)

Karsten Kettel

1954-12-01

Full Text Available The majority of cases of Bell's palsy are due to ischaemia of the facial nerve near the stylomastoid foramen. Following lack of blood supply the nerve loses its power of conduction, and venous stasis arises with ensuing swelling of the nerve, which becomes secondarily compressed within the Fallopian canal. The therapy of choice is medical treatment aiming to relieve the vasoconstriction and maintain the contractility of the muscles. Surgical decompression of the facial nerve is indicated in a limited number of cases, and the results of 108 operations are briefly recorded. Decompression should be performed in both fresh and relapsing palsies if no signs of spontaneous movement are observed after two months of observation. With patients in whom spontaneous recovery has ceased be-fored complete restitution has been obtained, further improvement may be expected from decompression.

Full Text Available Lesions of the nervus abducens, the 6th cranial nerve tend to be rare, usually occur suddenly following head injuries. A 43-year-old male patient presented with a history of fall from a height due to an occupational accident on the date of 11.01.2014. Cranial tomography demonstrated bilateral epidural hematoma. The epidural hematoma was drained during the operation. After the surgery, eye examination showed no vision loss, except limited bilateral lateral gaze. When the patient was unable to walk due to diplopia, he was advised to close one eye. On the right side, there were findings suggesting central facial paralysis. There may be multiple cranial nerve damage following head injury. Therefore, all cranial nerves should be thoroughly examined. [J Contemp Med 2016; 6(2.000: 110-113

Exploring vocal recovery after cranial nerve injury in Bengalese finches.

Urbano, Catherine M; Peterson, Jennifer R; Cooper, Brenton G

2013-02-08

Songbirds and humans use auditory feedback to acquire and maintain their vocalizations. The Bengalese finch (Lonchura striata domestica) is a songbird species that rapidly modifies its vocal output to adhere to an internal song memory. In this species, the left side of the bipartite vocal organ is specialized for producing louder, higher frequencies (≥2.2kHz) and denervation of the left vocal muscles eliminates these notes. Thus, the return of higher frequency notes after cranial nerve injury can be used as a measure of vocal recovery. Either the left or right side of the syrinx was denervated by resection of the tracheosyringeal portion of the hypoglossal nerve. Histologic analyses of syringeal muscle tissue showed significant muscle atrophy in the denervated side. After left nerve resection, songs were mainly composed of lower frequency syllables, but three out of five birds recovered higher frequency syllables. Right nerve resection minimally affected phonology, but it did change song syntax; syllable sequence became abnormally stereotyped after right nerve resection. Therefore, damage to the neuromuscular control of sound production resulted in reduced motor variability, and Bengalese finches are a potential model for functional vocal recovery following cranial nerve injury.

To study on relationship between diverse handling time following onset and clinical prognosis of cases with Bell palsy. Two hundred and sixteen cases with Bell palsy, who were admitted in our department between Jun. 2006 and Dec. 2009, were collected and divided into 6 groups according to disease time: 1-2 months, > 2 - 3 months, > 3 - 4 months, > 4 - 5 months, > 5 - 6 months, and > 6 months. Cases in all groups received subtotal course decompression of facial nerve and other compound treatment, and the relationship between handling timing and clinical prognosis were compared. It was found that the difference of prognosis and handling timing was statistically significant, after comparison between all groups with Facial Grading Standards (H-B) as the standard to assess prognosis. Clinical prognosis of cases with Bell palsy was related to alternative handling time, and subtotal course decompression of facial nerve was recommended to be performed as early as possible for those cases who were irresponsive after conservative treatment for one month.

Facial nerve schwannoma is a rare intracranial tumor. Treatment for this benign tumor has been controversial. Here, we report a case of extracranial facial nerve schwannoma treated successfully by hypo-fractionated CyberKnife (Accuray, Sunnyvale, CA) radiosurgery and discuss the efficacy of this treatment. A 34-year-old female noticed a swelling in her right mastoid process. The lesion enlarged over a seven-month period, and she experienced facial spasm on the right side. She was diagnosed with a facial schwannoma via a magnetic resonance imaging (MRI) scan of the head and neck and was told to wait until the facial nerve palsy subsides. She was referred to our hospital for radiation therapy. We planned a fractionated CyberKnife radiosurgery for three consecutive days. After CyberKnife radiosurgery, the mass in the right parotid gradually decreased in size, and the facial nerve palsy disappeared. At her eight-month follow-up, her facial spasm had completely disappeared. There has been no recurrence and the facial nerve function has been normal. We successfully demonstrated the efficacy of CyberKnife radiosurgery as an alternative treatment that also preserves neurofunction for facial nerve schwannomas.

We have analyzed the correlation between the House-Brackmann (HB) scale and Facial Nerve Grading System 2.0 (FNGS 2.0) in patients with Bell palsy, and evaluated the usefulness of the new grading system. Sixty patients diagnosed with Bell palsy from May 2009 to December 2010 were evaluated using the HB scale and FNGS 2.0 scale during their initial visit, and after 3 and 6 weeks and 3 months. The overall intraclass correlation coefficient (ICC) was 0.908 (P=0.000) and the Spearman correlation coefficient (SCC) was 0.912 (P<0.05). ICC and SCC displayed differences over time, being 0.604 and 0.626, respectively, at first visit; 0.834 and 0.843, respectively, after 3 weeks; 0.844 and 0.848, respectively, after 6 weeks; and 0.808 and 0.793, respectively, after 3 months. There was a significant difference in full recovery, depending on the scale used (HB, P=0.000; FNGS 2.0, P<0.05). The exact agreements between regional assessment and FNGS 2.0 for the mouth, eyes, and brow were 72%, 63%, and 52%, respectively. FNGS 2.0 shows moderate agreement with HB grading. Regional assessment, rather than HB grading, yields stricter evaluation, resulting in better prognosis and determination of grade.

(--Epigallocatechin gallate attenuates NADPH-d/nNOS expression in motor neurons of rats following peripheral nerve injury

Full Text Available Abstract Background Oxidative stress and large amounts of nitric oxide (NO have been implicated in the pathophysiology of neuronal injury and neurodegenerative disease. Recent studies have shown that (--epigallocatechin gallate (EGCG, one of the green tea polyphenols, has potent antioxidant effects against free radical-mediated lipid peroxidation in ischemia-induced neuronal damage. The purpose of this study was to examine whether EGCG would attenuate neuronal expression of NADPH-d/nNOS in the motor neurons of the lower brainstem following peripheral nerve crush. Thus, young adult rats were treated with EGCG (10, 25, or 50 mg/kg, i.p. 30 min prior to crushing their hypoglossal and vagus nerves for 30 seconds (left side, at the cervical level. The treatment (pre-crush doses of EGCG was continued from day 1 to day 6, and the animals were sacrificed on days 3, 7, 14 and 28. Nicotinamide adenine dinucleotide phosphate-diaphorase (NADPH-d histochemistry and neuronal nitric oxide synthase (nNOS immunohistochemistry were used to assess neuronal NADPH-d/nNOS expression in the hypoglossal nucleus and dorsal motor nucleus of the vagus. Results In rats treated with high dosages of EGCG (25 or 50 mg/kg, NADPH-d/nNOS reactivity and cell death of the motor neurons were significantly decreased. Conclusions The present evidence indicated that EGCG can reduce NADPH-d/nNOS reactivity and thus may enhance motor neuron survival time following peripheral nerve injury.

Background Facial nerve paralysis in a patient with a salivary gland mass usually denotes malignancy. However, facial paralysis can also be caused by benign salivary gland tumors. Methods We present a case of facial nerve paralysis due to a benign salivary gland tumor that had the imaging characteristics of an intraparotid facial nerve schwannoma. Results The patient presented to our clinic 4 years after the onset of facial nerve paralysis initially diagnosed as Bell palsy. Computed tomography demonstrated filling and erosion of the stylomastoid foramen with a mass on the facial nerve. Postoperative histopathology showed the presence of a pleomorphic adenoma. Facial paralysis was thought to be caused by extrinsic nerve compression. Conclusions This case illustrates the difficulty of accurate preoperative diagnosis of a parotid gland mass and reinforces the concept that facial nerve paralysis in the context of salivary gland tumors may not always indicate malignancy.

1991-01-01

Because of advances in CT and MR imaging, accurate identification and evaluation of cranial nerve lesions is now possible. Cranial nerves III, IV, and VI, providing motor and sensory control of the eye, can be evaluated as a unit. In this paper, the authors present an overview of the anatomy and pathology of these cranial nerves. We first illustrate their normal anatomic pathways from the brain stem to the orbit. This is followed by clinical examples of patients with a variety of isolated and complex palsies of these three cranial nerves. This is accomplished by inclusion of ocular photographs, correlative imaging studies, and the use of diagrams. Knowledge of the gross and imaging anatomy and the ophthalmologic manifestations of pathology affecting these three cranial nerves permits a tailored approach to their evaluation

Purpose In this study the authors evaluate the clinical outcomes in patients with radial nerve palsy who underwent nerve transfers utilizing redundant fascicles of median nerve (innervating the flexor digitorum superficialis and flexor carpi radialis muscles) to the posterior interosseous nerve and the nerve to the extensor carpi radialis brevis. Methods A retrospective review of the clinical records of 19 patients with radial nerve injuries who underwent nerve transfer procedures using the median nerve as a donor nerve were included. All patients were evaluated using the Medical Research Council (MRC) grading system. Results The mean age of patients was 41 years (range 17 – 78 years). All patients received at least 12 months of follow-up (20.3 ± 5.8 months). Surgery was performed at a mean of 5.7 ± 1.9 months post-injury. Post-operative functional evaluation was graded according to the following scale: grades MRC 0/5 - MRC 2/5 were considered poor outcomes, while MRC of 3/5 was a fair result, MRC grade 4/5 was a good result, and grade 4+/5 was considered an excellent outcome. Seventeen patients (89%) had a complete radial nerve palsy while two patients (11%) had intact wrist extension but no finger or thumb extension. Post-operatively all patients except one had good to excellent recovery of wrist extension. Twelve patients recovered good to excellent finger and thumb extension, two patients had fair recovery, five patients had a poor recovery. Conclusions The radial nerve is a commonly injured nerve, causing significant morbidity in affected patients. The median nerve provides a reliable source of donor nerve fascicles for radial nerve reinnervation. This transfer was first performed in 1999 and evolved over the subsequent decade. The important nuances of both surgical technique and motor re-education critical for to the success of this transfer have been identified and are discussed. PMID:21168979

Full Text Available Introduction: According to the high incidence of Bell's palsy (IFP and lack of clinical data regarding different aspects of disease, the present study investigated 121 Iranian patients with peripheral facial paralysis referred to the emergency department. Methods: In this retrospective study, all patients with peripheral facial paralysis, referred to the emergency department of Poursina hospital, Rasht, Iran, from August 2012 to August 2013, were enrolled. For all patients with diagnosis of Bell's palsy variables such as age, sex, occupation, clinical symptoms, comorbid disease, grade of paralysis, and the severity of the facial palsy were reviewed and analyzed using STATA version 11.0. Results: A total of 121 patients with peripheral facial paralysis were assessed with a mean age of 47.14±18.45 years (52.9% male. The majority of patients were observed in the summer (37.2% and autumn (33.1% and the recurrence rate was 22.3%. The most common grades of nerve damage were IV and V based on House- Brackman grading scale (47.1%. Also, the most frequent signs and symptoms were ear pain (43.8%, taste disturbance (38.8%, hyperacusis (15.7% and increased tearing (11.6%. There were not significant correlations between the severity of palsy with age (p= 0.08, recurrence rate (p=0.18, season (p=0.9, and comorbid disease including hypertension (p=0.18, diabetes (p=0.29, and hyperlipidemia (p=0.94. The patients with any of following symptoms such as ear pain (p<0.001, taste disturbance (p<0.001, increased tearing (p=0.03, and Hyperacusis (p<0.001 have more severe palsy. Conclusion: There was equal gender and occupational distribution, higher incidence in fourth decade of life, higher incidence in summer and autumn, higher grade of nerve damage (grade V and VI, and higher incidence of ear pain and taste disturbance in patients suffered from IFP. Also, there was significant association between severity of nerve damage and presence of any simultaneous symptoms. 

The lower cranial nerves: IX, X, XI, XII.

The lower cranial nerves innervate the pharynx and larynx by the glossopharyngeal (CN IX) and vagus (CN X) (mixed) nerves, and provide motor innervation of the muscles of the neck by the accessory nerve (CN XI) and the tongue by the hypoglossal nerve (CN XII). The symptomatology provoked by an anomaly is often discrete and rarely in the forefront. As with all cranial nerves, the context and clinical examinations, in case of suspicion of impairment of the lower cranial nerves, are determinant in guiding the imaging. In fact, the impairment may be located in the brain stem, in the peribulbar cisterns, in the foramens or even in the deep spaces of the face. The clinical localization of the probable seat of the lesion helps in choosing the adapted protocol in MRI and eventually completes it with a CT-scan. In the bulb, the intra-axial pathology is dominated by brain ischemia (in particular, with Wallenberg syndrome) and multiple sclerosis. Cisternal pathology is tumoral with two tumors, schwannoma and meningioma. The occurrence is much lower than in the cochleovestibular nerves as well as the leptomeningeal nerves (infectious, inflammatory or tumoral). Finally, foramen pathology is tumoral with, outside of the usual schwannomas and meningiomas, paragangliomas. For radiologists, fairly hesitant to explore these lower cranial pairs, it is necessary to be familiar with (or relearn) the anatomy, master the exploratory technique and be aware of the diagnostic possibilities.

We examined the clinical records of 468 facial palsy patients who were treated with an antiviral drug in combination with either oral or intravenous corticosteroids in participating hospitals between 2010 and 2014. Patients were divided into a Bell's palsy group or a Hunt's palsy group. We used the Yanagihara facial nerve grading system to grade the severity of facial palsy. "Recovery" from facial palsy was defined as achieving a Yanagihara score ≥36 points within 6 months of onset and having no accompanying facial contracture or synkinesis. We collected information about pretreatment hematologic findings, demographic data, and electrophysiologic test results of the Bell and Hunt group patients who recovered and those who did not. We then compared these data across the 2 palsy groups. In the Bell's palsy group, recovered and unrecovered patients differed significantly in age, sex, electroneuronography score, stapedial muscle reflex, neutrophil rate, lymphocyte rate, neutrophil-to-lymphocyte ratio, and initial Yanagihara score. In the Hunt's palsy group, recovered and unrecovered patients differed in age, electroneuronography score, stapedial muscle reflex, monocyte rate, platelet count, mean corpuscular volume, and initial Yanagihara score. Pretreatment hematologic findings, which reflect the severity of inflammation and bone marrow dysfunction caused by a virus infection, are useful for predicting the prognosis of facial palsy. © American Academy of Otolaryngology—Head and Neck Surgery Foundation 2016.

Quadriceps palsy is mainly caused by proximal lesions in the femoral nerve. The obturator nerve has been previously used to repair the femoral nerve, although only a few reports have described the procedure, and the outcomes have varied. In the present study, we aimed to confirm the feasibility and effectiveness of this treatment in a rodent model using the randomized control method. Sixty Sprague-Dawley rats were randomized into two groups: the experimental group, wherein rats underwent femoral neurectomy and obturator nerve transfer to the femoral nerve motor branch; and the control group, wherein rats underwent femoral neurectomy without nerve transfer. Functional outcomes were measured using the BBB score, muscle mass, and histological assessment. At 12 and 16 weeks postoperatively, the rats in the experimental group exhibited recovery to a stronger stretch force of the knee and higher BBB score, as compared to the control group (p nerve with myelinated and unmyelinated fibers was observed in the experimental group. No significant differences were observed between groups at 8 weeks postoperatively (p > 0.05). Obturator nerve transfer for repairing femoral nerve injury was feasible and effective in a rat model, and can hence be considered as an option for the treatment of femoral nerve injury.

Neuropsychiatric side effects of long-term recombinant interferon-α therapy consist of a large spectrum of symptoms. In the literature, cranial neuropathy, especially Bell's palsy, and movement disorders, have been reported much less often than other neurotoxic effects. We report a case of Bell's palsy in a patient with chronic hepatitis C during peginterferon-α and ribavirin therapy. The patient subsequently developed clinically inapparent facial nerve involvement on the contralateral side and showed an increase in choreic movements related to Huntington's disease during treatment.

Our objective was to assess the prognostic value of measurements of the degree of contrast enhancement of the intratemporal segments of the facial nerve. We prospectively obtained MRI, slice thickness <1 mm of 20 patients with a facial palsy on the first day of inpatient treatment, and measured contrast enhancement of the nerve. The data were compared with compound muscle action potential (CMAP) measurements and the clinical course. Analysis of the initial enabled differentiation of three patients whose palsy was to show no improvement from 17 whose palsy was to resolve as expected. No patient with a poor outcome showed lesser increase in signal in the internal auditory canal, pars tympanica and pars mastoidea than patients who fully recovered. In no patient who had been diagnosed on the basis of the initial MRI as having a ''normal'' palsy was the amplitude of the (CMAP) reduced to less than 20% that of the normal side. Measurement of contrast enhancement was thus shown to be a prognostic indicator and may provide a basis for a differential treatment of facial palsy. (orig.)

While standardized methods are established to examine the pathway from motorcortex to the peripheral nerve in patients with facial palsy, a reliable method to evaluate the facial muscles in patients with long-term palsy for therapy planning is lacking. A 3D ultrasonographic (US) acquisition system driven by a motorized linear mover combined with conventional US probe was used to acquire 3D data sets of several facial muscles on both sides of the face in a healthy subject and seven patients with different types of unilateral degenerative facial nerve lesions. The US results were correlated to the duration of palsy and the electromyography results. Consistent 3D US based volumetry through bilateral comparison was feasible for parts of the frontalis muscle, orbicularis oculi muscle, depressor anguli oris muscle, depressor labii inferioris muscle, and mentalis muscle. With the exception of the frontal muscle, the facial muscles volumes were much smaller on the palsy side (minimum: 3% for the depressor labii inferior muscle) than on the healthy side in patients with severe facial nerve lesion. In contrast, the frontal muscles did not show a side difference. In the two patients with defective healing after spontaneous regeneration a decrease in muscle volume was not seen. Synkinesis and hyperkinesis was even more correlated to muscle hypertrophy on the palsy compared with the healthy side. 3D ultrasonography seems to be a promising tool for regional and quantitative evaluation of facial muscles in patients with facial palsy receiving a facial reconstructive surgery or conservative treatment.

Phrenic nerve palsy remains the most frequent complication associated with cryoballoon-based pulmonary vein (PV) isolation. We sought to characterize our experience using a novel monitoring technique for the prevention of phrenic nerve palsy. Two hundred consecutive cryoballoon-based PV isolation procedures between October 2010 and October 2013 were studied. In addition to standard abdominal palpation during right phrenic nerve pacing from the superior vena cava, all patients underwent diaphragmatic electromyographic monitoring using surface electrodes. Cryoablation was terminated on any perceived reduction in diaphragmatic motion or a 30% decrease in the compound motor action potential (CMAP). During right-sided ablation, a ≥30% reduction in CMAP amplitude occurred in 49 patients (24.5%). Diaphragmatic motion decreased in 30 of 49 patients and was preceded by a 30% reduction in CMAP amplitude in all. In 82% of cases, this reduction in CMAP amplitude occurred during right superior PV isolation. The baseline CMAP amplitude was 946.5±609.2 mV and decreased by 13.8±13.8% at the end of application. This decrease was more marked in the 33 PVs with a reduction in diaphragmatic motion than in those without (40.9±15.3% versus 11.3±10.5%; Pphrenic nerve palsy persisted beyond the end of the procedure, with all cases recovering within 6 months. Despite the shortened application all veins were isolated. At repeat procedure the right-sided PVs reconnected less frequently than the left-sided PVs in those with phrenic nerve palsy. Electromyographic phrenic nerve monitoring using the surface CMAP is reliable, easy to perform, and offers an early warning to impending phrenic nerve injury. © 2014 American Heart Association, Inc.

Facial nerve schwannoma localized in the middle fossa is a rare lesion. We report a case of a facial nerve schwannoma in a 30-year-old male presenting with facial nerve palsy. Magnetic resonance imaging (MRI) showed a 3 cm diameter tumor of the right middle fossa. The tumor was removed using a sub-temporal approach. Intraoperative monitoring allowed for identification of the facial nerve, so it was not damaged during the surgical excision. Neurological clinical examination at discharge demonstrated moderate facial nerve improvement (Grade III House-Brackmann).
