Bell's PalsyThe aim of this study is to compare the effects of prednisolone and staging acupuncture in the recovery of the affected facial nerve, and to verify that whether in combination with staging acupuncture is more effective than prednisolone alone for Bell's palsy in a large number of patients.
Artificial Eye Blinking Stimulation Following Paralysis of the Facial Nerve
Facial ParalysisBell PalsyArtificial eye blinking stimulation following damage to the facial nerve. Group 1 - Patients with a persistent unilateral facial paralysis (palsy) that underwent an operation for facial reanimation Group 2 - Patients with temporary unilateral facial paralysis, secondary to unilateral Bell's palsy. Primary objective: To evaluate whether the Neurotigger device can elicit a complete or a partial eyelid closure of the affected eye. Secondary objective: To optimize the location of the Neurotrigger's electrodes, and define the level of the pain generated, if any, during device implementation and stimulation, as well as the method for the personal adjustment of the precise pattern of stimulation (strength, intensity, other features) to achieve eye blinking for different patients.
Do We Need to Taper Down Steroid Therapy for Bell's Palsy
Bell PalsyBell's palsy [BP] is defined as acute idiopathic peripheral facial palsy or paralysis. Additional symptoms frequently include pain around or behind the ear, impaired tolerance to ordinary levels of noise and disturbed sense of taste on the same side. It affects men and women more or less equally. There is a consensus in the literature regarding the importance of steroid treatment for improving recovery rates and sequela of BP. Moreover, there is increasing level of high quality of evidence in recent years for a combined antiviral and steroids treatment for severe BP (House Brackmann [HB] 5-6). Adverse effects (AEs) were reported in 1-12% of patients treated with steroids, antivirals or placebo. The AEs reported were dyspepsia, loss of blood sugar control, headache, fatigue, dizziness and insomnia, recurrent duodenal ulcers, mood swings, and acute psychosis. All effects resolved when treatment was stopped. Although steroid and antivirals are widely used for BP, there is a high variability of steroids treatment, both in the dosage given and in the way of tapering down. Among the different steroid regimens used were: prednisone 1 mg/kg for 5 days tapered to 10 mg/day for remaining 5 days; prednisone (1 mg/kg for 10 days then tapered to zero over the next 6 days); prednisolone 60 mg for 5 days, 30 mg for 3 days, and 10 mg for 2 days. House-Brackmann (HB) system is widely used for facial function assessment. It is based on a six-grade score, where grade I is normal function, grade VI is complete absence of facial motor function, and grades II to V are intermediate. Steroid-induced side effects generally require tapering of the drug as soon as the disease being treated is under control. Tapering must be done carefully to avoid both recurrent activity of the underlying disease and possible cortisol deficiency resulting from hypothalamic-pituitary-adrenal axis (HPA) suppression. However, according to a review by Furst et al (2019), a patient who has received any dose of glucocorticoid for less than 3 weeks or patients treated with alternate-day prednisone at a dose of less than 10 mg (or its equivalent) are unlikely for HPA suppression. They concluded that short-term glucocorticoid therapy (up to three weeks), even if at a fairly high dose, can simply be stopped and need not to be tapered.. According to the above, the investigators assume that a rapid withdrawal of steroids after short course of treatment for BP should neither influence the efficacy or safety of treatment. Finally, steroid regimen may be hard to follow for some patients and can results in confusion and frustration. Simplifying steroid regimen, such as skipping withdrawal if not necessary, may solve this problem. The objective of our study is to determine the effectiveness and safety of prednisone treatment with no tapering down for Bell's Palsy.
Facial Function Reanimation by Electrical Pacing in Unilateral Facial Paralysis.
Facial Nerve PalsyPurpose of the trial is to study the activations of paralyzed facial muscles in a unilateral facial nerve palsy with a multi-channel electrical stimulator. The principle of the device is to measure muscle activity of the healthy side of the face by surface electromyography (EMG) and to use this information to stimulate the corresponding muscles of the paralyzed side. The ultimate goal is to develop a prosthetic device for persons with a facial nerve palsy. The trial consists of several different studies. The studies' aims are 1. To study activations of paralyzed facial muscles by the electrical stimulation. 2. To study different stimulation pulse waveforms, frequencies, and electrode placement and their effect on the muscle activations and the tolerability of the stimulation. 3. To study whether a symmetrical movement on the paralyzed side can be achieved with electrical stimulation when compared to the movements of the healthy side. 4. To study tolerability of stimulation-elicited eye blink when watching a film and the effect of the stimulation-induced blink on the eye symptoms, the visual acuity, and the effects of the stimulation on the lacrimal fluid. 5. To develop a method for facial pacing, i.e. measuring the muscle activations on the healthy side of the face and to use this information to stimulate and activate the healthy side of the face. Forty subjects with a chronic facial nerve palsy are recruited to the studies. Each subject can participate in one or several studies. Another forty subjects with an acute facial nerve palsy are recruited to the study on the tolerability and effect on the eye symptoms. Additionally, altogether ninety healthy volunteers are recruited to the studies in order to gather preliminary information on the tolerability and the effects of the stimulations.
Ancillary Procedures in Patients of Refractory Facial Palsy Patients Selection and Evaluation of...
Facial PalsyIntroduction: There are numerous causes of facial palsy (FP), though hemifacial weakness is often generally termed Bell's palsy, named after the Scottish neurologist Charles Bell, who described sudden onset unilateral facial paralysis in 1821. Virally triggered, acute FP, to which the term Bell's palsy (BP) refers, is one of the most common, and fortunately the most likely condition to result in eventual return to premorbid status; 70% to 90% of patients recover spontaneously. Other causes of FP routinely result in poorer recovery, and the clinician must discern among these to formulate a treatment plan. In facial palsy, paralysis of muscles on the affected side of the face results in loss of forehead creases, loss of the nasolabial fold, lagophthalmos, brow droop, and drooping of the corner of the mouth. In contrast, muscles on the unaffected side of the face no longer have opposing forces. This may cause difficulty in articulation, eating, drinking, and is often cosmetically unacceptable to patients because of asymmetry, especially when speaking, smiling, and laughing. There are significant psychological effects as patients lack the confidence to carry out many daily activities in public, such as appearing in photographs. Although management is difficult, there are a range of reanimation options available. These include nerve grafts, muscle transfers, myofunctional approaches, and microsurgical patches usually for the more severe facial palsies (House-Brackmann grades 4 to 6). However, despite these procedures, facial symmetry may not improve.
Surgery or Clincial Follow up, in Patients With Bell' s Palsy
Bell PalsyThe purpose of this study is to investigate if an early surgical intervention on patienst with Bell´s Palsy has a better impact on their facial muscular function and their quality of life as compared to conventional therapy.
Intratympanic Stereoidal Injections for Facial Nerve Palsy
Bell PalsyBell's palsy is defined as a facial nerve palsy without any other known cause. The common practice for this disease consists of the use of oral steroids. Such treatment can cause harm to people who have disabilities or prior conditions such as pregnancies, diabetes, obesity and/or high blood pressure. While the use of intratympanic injection for sudden sensory hearing loss is well rehearsed in many practices, similar management of facial nerve palsy due to Bell's phenomenon is rare and a few researches have been conducted regarding the subject. In this research we suggest intratympanic injections for these patients as a treatment for Bell's palsy.
Effect of Stellate Ganglion Block Combined With Facial Nerve Block on the Treatment of Idiopathic...
Peripheral Facial PalsyPeripheral facial palsy is caused by damage to the facial nerve at any site of the peripheral branches after the facial nucleus.Stellate ganglion block is performed to treat peripheral facial palsy because it increases blood flow and promotes nerve regeneration.Facial Nerve Block worked with elimination of local inflammation of nerve and oppression. Facial nerve block is a treatment that inject drugs into the damaged nerve around to eliminate local inflammation and compression of the nerve.
Cognitive Function and Emotional Possessing in Bilateral Facial Palsy
IntelligenceEmotionBased on recent findings that botulinum toxin injections in the cranial muscles might reduce emotional processing (Havas 2011), an increasing number of popular newspaper tabloids are suggesting a negative effect on cognition. The underlying research articles address the "facial feedback hypothesis". The hypothesis indicates that expressive behaviour, including facial mimic expressions influences the subject's brain via feedback. (Alam 2008) Other systemic neurological diseases, e.g of inflammatory origin, may lead to temporary bilateral facial nerve palsy (BF). During recovery process, the palsy usually remits completely. The effect of bilateral facial muscle palsy on cognition and emotional possessing has never been evaluated. The results of this pilot study might provide new information about the effect bilateral facial palsy on emotional processing and cognition and the facial feedback hypothesis. The aim of this controlled pilot study is to assess cognitive function and emotional processing in patients with bilateral facial palsy. In addition, differences in cognitive function and emotional processing in patients with different manifestations of dystonia should be evaluated. According to the facial feedback theory, paralysed mimic muscles might alter emotional processing. Therefore, investigators compare patients with bilateral facial muscle palsy and healthy controls. Investigators expect no influence of facial muscle palsy on cognitive functions in any of the tested groups; the investigators expect a mild impairment of emotional processing only in the patients group with bilateral facial muscle palsy (BEB and BF). In addition, the investigators expect no difference in emotional processing in patients with different manifestations of dystonia (BEB and CD) at remission. There might be a slight difference of emotional processing in patients with different manifestations of dystonia (BEB and CD) at time of prominent facial palsy.
