Filter by:Respiratory function, phonation and facial expressivity are related to emotional reaction through neurophysiological process. Specific emotional respiratory, vocal and facial patterns had been described in literature. Respiratory cycles variation is modulated by stimulus arousal. Furthermore, inspiratory-to-expiratory time ratio in abdominal area is modulated by emotional valence. Inextricably linked to respiration, vocal production depends on emotional arousal and valence too. According to embodied cognition, the effector pattern of an emotion initiates the corresponding subjective activation. Facial recognition is influenced by automatic mimicry and facial feedback. Most facial feedback studies included patients with diplegia but few studies dealt with emotional perception in Bell's palsy. The aim of the present study is to understand production and perception of emotion in Bell's palsy with respiratory, vocal and facial markers. What impact lack of mimicry have on physiological emotional reaction in Bell's palsy? To this end, prospective monocentric study will be conducted with 60 patients with Bell's Palsy from grade II to grade VI of House & Brackmann's scale. During production and perception of vocal and facial expression, respiratory rate and thoraco-abdominal movements will be analyzed. The investigators hypothesize that severity of facial deficit is negatively correlated with variation of respiratory cycles, lower segmental and suprasegmental changes during vocal expression, and lower facial perception (congruency and arousal).
Inadequate recovery from Bell's palsy is not uncommon and as consequence, physical and social impairment are exist in these patients. The medical options for chronic condition of Bell's palsy are insufficient. Low-level laser therapy has shown a favorable prognosis in the regeneration of peripheral nerves. Moreover, laser acupuncture therapy (LAT) become widely used method to stimulate acupuncture points, but its efficacy as treatment method for Bell's palsy and during the chronic stage is unclear.
Facial palsy is a serious and disabling disease whose drudgery and sensation are probably underestimated. Psychological, social and economic issues have major impacts although vital prognosis is not engaged in this pathology. Facial palsy remains a personal drama for patient. Consequences may take the form of: aesthetic deformation, modification of body image, with socio-professional consequences. Beside unsightly facial aspects, weakness of facial muscles can cause troubles in eating, drinking, talking, communicating personal emotions and communication. Facial palsy impacts patients' quality of life (QOL) and affects mental health. This wide multidimensional concept usually includes self-measures of physical and mental health. QOL is evaluated with general and specific scales. General scales allow to compare QOL of different diseases, when specific scales focus on one disease and consider all aspects related to this disease and therefore are more appropriate and sensitive in dimensions related to patient disease and health. "Facial disability Index" (FDi) and "Facial Clinimetric Evaluation" (FaCE) are the most used validated questionnaires to assess QOL of patients suffering from peripheral facial palsy (PFP). There is no existing validated questionnaire or scale in French version despite many French studies on PFP available. Using these questionnaires in French language requires translation and strict approval of the new language version. The aim of the study is to translate and validate French versions of specific scales of QOL in peripheral facial palsy patients: FDI and FaCE. Secondary objective is to evaluate QOL of patients depending on PFP etiology. Translation process will be done respecting internationally recognized rules. A pilot study will be performed on 5 physicians and 5 patients in order to validate the questionnaires translations. French versions obtained will be used for their validation on 80 patients suffering from PFP. Cronbach's alpha will be estimated to check internal consistency of FDI and FaCE scales. Test re-test reliability will be calculated with inter-class correlation, reiterating questionnaires one week later. Scores of FDI and FaCE scales will be compared to other clinical evaluation scales, estimating correlation coefficient. Social function of FDI and FaCE scales will be compared with general scale SF-36 scores, estimating a correlation coefficient.
Facial nerve paralysis is due to inflammation around the facial nerve. Current treatment for facial nerve paralysis is a 10 day course of oral steroids (which will reduce the inflammation), with electrodiagnostic testing. There have been limited studies on the use of intratympanic steroid injection, in addition to oral steroid, in the recovery of facial nerve paralysis. There are indications that the use of intratympanic injections, in addition to the oral steroids, will speed up the recovery rate of the facial nerve paralysis, as well as improve the complete recovery of the facial nerve paralysis. This study will randomize patients with facial nerve paralysis into two groups: 1) oral steroid only and 2) oral steroid plus a 3 intratympanic steroid injections spaced out over three weeks. There are a subset of patients that are unable to take oral steroids for medical reasons (such as diabetes); these patients will be placed into a third group and only receive 3 intratympanic steroid injections space out over three weeks. Subjects that are to receive the intratympanic injection will receive pre- and post-hearing exams as part of their standard of care. Patients will be evaluated via videorecording by two blinded investigators as well as in person evaluations by the unblinded treating physician. Subjects will be followed until complete facial nerve paralysis recovery or one year post-treatment, whichever comes first.
Purpose 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.
Facial nerve paralysis is a disfiguring complication which occurs in 7-10 % of temporal bone fractures. The onset of paralysis may be immediate, delayed or undetermined, the latter of which often occurs in unconscious patients with accompanying life-threatening complications.About one fourth has complete paralysis.
This is a randomized, single blinded, non-placebo controlled that will compare one group of Bells Palsy patients receiving the current standard of care including oral corticosteroids and oral antivirals against an experimental group receiving the current standard of care in addition to hyperbaric oxygen therapy. Outcome assessment will be based on both objective analyses of facial movements as well as subjective quality of life scales.
Bell'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.
The facial paralysis is a frequent disease causing important functionals swallowing dysfunctions. The purpose of our study was to evaluate the improvement of the swallowing disorders after surgery by lengthening temporalis myoplasty (LTM) in the facial paralysis. This prospective study has realised on the following of patients affected by facial paralysis treated by LTM. Self-administered questionnaires and clinics tests had realized to analyze three components oh the oral phase of the swallowing ( drooling, mastication and handicap). The evaluations was realized before the surgery and at 3 and 6 months after .
The problem posed is the possibility of objectively assessing facial muscle mobility. Today, in patients with facial paralysis, the assessment of the deficit is carried out using a subjective scale such as the House Brackman [1] or EMG scale of the facial nerve but does not distinguish each muscle individually . Objective measurements of skin muscles such as thickness and volume, in preoperative assessment of a facial paralysis rehabilitation surgery, would be useful in order to choose the most appropriate surgical technique. Indeed, too much amyotrophy will contraindicate hypoglosso-facial anastomosis (VII-XII) and it will be preferable to propose a temporal elongation myoplasty or a reinfused free muscle flap. Similarly, it would be useful to be able to objectively evaluate the recovery of muscle function after facial allo-transplantation. Although electromyography has been developed since the work of Duchenne de Boulogne, little research has been carried out on the development of noninvasive methods to objectively characterize in vivo skin muscles (variation, position, orientation, morphometry). The main morphometric data of the skin muscles come from anatomical dissections. Imaging of the skin muscles has not been specifically developed. Some studies have been carried out to visualize these muscles in MRI 1.5 Tesla in pathologies such as myasthenia gravis, facial paralysis, and labio-alveolo-palatine clefts for example. The originality of the project is to develop a method allowing to establish a quantitative correlation between the movements of the face and the muscular changes. This correlation will be achieved by associating muscular morphological data derived from MRI acquisitions and cutaneous deformations resulting from clinical examinations. This non-invasive approach should make it possible to establish objective and reproducible indicators in patients with facial paralysis sequelae.
