Among studies that reported patient gender, 653 (70.6%) patients were female, 271 (29.3%) were male, and 66 were not described. The manuscript will undergo copyediting, typesetting, and review of the resulting proof before it is published in its final form. Treatment depends on the cause, but is largely conservative with facial retraining or mime therapy, if needed, while Botox and surgery are used as last resort. Description of Patients in Included Studies, by Treatment Modality. Full-text English language articles of cohort studies or randomized controlled trials on synkinesis treatment were eligible for inclusion. Surgery may be a reasonable option if conservative therapy fails. [15], The basis of this hypothesis is as follows: after a lesion, axonal degeneration (via Wallerian degeneration) occurs. All authors agree to accountable for all aspects of the work. Neuromuscular retraining for the patient with a hypoglossal (XII) anastomosis is similar to treatment of synkinesis. To smile, lip pucker, chew) the eye on the affected side will partially/fully close. You also have the option to opt-out of these cookies. Instead of the characteristic upward curl at the angle of the mouth (a smile), s/he has a drawing down at the angle of the mouth (a grimace). PT is often utilized adjunctively in synkinesis management. The muscles that control facial movements can also become damaged when a nerve is damagedsuch as when theres trauma to the face. None of the 33 included studies directly compared different treatment categories. In some cases, patients experience decreased synkinesis after the injection effects have worn off.81. This strategy yielded 1250 citations; 592 remained after deduplication. Previously, many developed treatment strategies (that inevitably failed) were invented based on the original hypothesis by only focusing on the lesion site for improving the organization of regeneration. Many clinicians may also use digital photography and video to score a patients facial paralysis and synkinesis. In summary, our results indicate that surgery is likely safe for management, but it is not supported by sufficient data to be superior. This page was last edited on 29 January 2023, at 01:19. The https:// ensures that you are connecting to the Facial muscles contain few to none intrinsic muscle sensory receptors (used for proprioceptive feedback) and additionally they do not span movable joints and so lack joint receptors (another source for proprioceptive feedback).

Our website is not intended to be a substitute for professional medical advice, diagnosis, or treatment. Botulinum toxin A treatment in facial palsy synkinesis: a systematic review and meta-analysis. Synkinesis can cause functional limitation with activities such as eating, drinking, smiling, and may even lead to social isolation. There is no evidence-based, definitive answer for this question. The chemodenervation group was the most consistent in reporting variables of interest such as age, facial palsy etiology, and adverse effects. Many studies failed to include detailed information about treatment schedules.

Additionally, complete information about post-treatment assessment intervals were not available for most studies, so timeframes of observed results remain unclear. HHS Vulnerability Disclosure, Help Background: Synkinesis is defined as involuntary movements accompanying by voluntary movements and can occur during the aftermath of peripheral facial palsy, causing functional, aesthetic and psychological problems in the patient. 2022 Oct;43(10):1470-1475. doi: 10.3174/ajnr.A7619. There are lack of high evidence level data for robust comparisons of post-paretic synkinesis treatments, however, this condition is likely effectively treated non-surgically and requires the support of a specialized multi-disciplinary team. The EFACE scoring system is used to assess patients at rest, with dynamic facial movement and to also assess severity of synkinesis. Recovery is not easy, but it is possible to improve your facial appearance and muscle control with therapy, medication, or surgery. Examples include: Other less common variations of synkinesis involving the cranial nerves include: Bimanual Synkinesis occurs when left and right upper limbs, especially the hands and fingers execute exactly the same movement even though only one hand is intentionally moved. This accommodation-convergence synkinesis can result in esotropia, or eyes that turn in when the ratio between accommodation and convergence is unusually high. As the patient becomes adept at performing these movement patterns, s/he can begin to dissociate tongue from facial movements. The patient should be followed monthly to record changes, modify the home program and monitor for the development of synkinesis. By clicking Accept, you consent to the use of ALL the cookies. This occurs due to irregular healing and regeneration of the nerves that control facial movements after they have been damaged. 5215 Torrance Blvd., #300, In congenital cases, mutations of genes involved in nerve growth, specifically axonal growth have been found. Surgical indications included segmental paresis, aesthetic disturbance, and synkinesis refractory to chemodenervation. These cookies do not store any personal information. Facial twitching, especially in the cheek and sometimes the chin, is also a form of synkinesis. [18] Thus, biofeedback allows the patient to actively sense the motion of their muscles. Future studies must address the need for: 1) uniform outcome reporting with 2) comparative treatment groups and 3) long term follow-up. Its analyses can allow for treatment options to be evaluated. [24] Due to the short span of Botox effects though, patients must come back to the doctor for re-injection approximately every 3 months. Epub 2022 Dec 22. Therapy may involve one or more of these options. Prolonged lack of eye closure and lacrimation may lead to ophthalmologic referral for gold weight, spring placement or other procedure. The average age of the total patient cohort was 46.4 years. Additionally, a common treatment option for facial palsy is to use electrical stimulation. Unfortunately, meta-analysis was simply not possible due to extreme heterogeneity in the literature. [19] The subsequent role of the patient is to control the movement of undesired muscle during volitional movement by incorporating the information perceived through the EMG. Two additional steps to the ones described for synkinesis are required to improve motor control: Step 1 The patient allows movement of the tongue to initiate facial movement, but only until s/he begins to make minimal movements of the face without activating the tongue. Physical therapy techniques can involve neuromuscular retraining exercises (exercises that train nerves and muscles to communicate) and biofeedback (electrical signals from muscles help the person learn to control the muscles). Join for free today. The Newcastle-Ottawa tool assesses the representativeness of the cases and controls in the cohort, ascertainment of exposure, and quality of reported outcomes. 2017. Synkinesis typically does not require an imaging study to diagnose. Botulinum toxin injections can help a little to reduce the overactivity of muscles but injections alone will not resolve the facial movement long term. Seven prospective cohort studies, 23 retrospective cohort studies, and 3 randomized controlled trials met inclusion criteria. The raters will use the Sunnybrook Facial Grading System to assess each video and rate improvement of synkinesis after administration of the study drug. It affects each patient differently. Chemodenervation studies showed an average post-intervention improvement of 17.8% (range 11 to 33.3%), with PT improving by 29.7% (range 14.6 to 41.2%), surgery by 16.6% (range 4.7 to 41%) and combination therapy by 20.4% (range 5.13 to 37.5%). As the patient becomes proficient in performing the exercise, inhibition of synkinesis requires less concentration, and excursion of the primary movement increases as control is learned. Since the post-synaptic cell is hypersensitive, the neurotransmitters that reach it from an axon of another nerve will successfully provide stimulation. Some of the data that are collected include the number of visitors, their source, and the pages they visit anonymously. Among those that did provide schedules, provider-led in-person sessions ranged from as infrequent as once monthly to as often as three times per week. The treatment typically lasts for a few months at a time, and it can be repeated. Heidi Moawad is a neurologist and expert in the field of brain health and neurological disorders. Synkinesis refers to the abnormal involuntary facial movement that occurs with voluntary movement of a different facial muscle group. Institutional Review Board Approval: This study did not require approval by the Human Research Protection Office at Washington University in St. Louis given it was a review of publicly available data. 1Division of Plastic and Reconstructive Surgery, Department of Surgery, Washington University School of Medicine, St. Louis, Missouri, 2Division of Reconstructive Microsurgery, Department of Plastic Surgery, Chang Gung Memorial Hospital, Chang Gung University, Taoyuan, Taiwan, 3Section of Plastic Surgery, Department of Surgery, University of Michigan, Ann Arbor, Michigan, 4Becker Medical Library, Washington University School of Medicine, 5Division of Public Health Sciences, Washington University School of Medicine. It is usually acquired. Purpose of Review Facial synkinesis is a sequela of facial nerve injury that results in involuntary facial movement occurring simultaneously with volitional facial movement. It is the consequence of normal axonal growth from a proximal site of injury into the "wrong" distal target muscles; as a result, patients may experience eye closure with smile or vice versa. Table 1 summarizes the characteristics of included studies. The facial nerve fibers can implant into the different muscles in cases of Bell's palsy. The effects of Botox have shown to be remarkable, with synkinetic symptoms disappearing within 2 or 3 days. Considering the lack of control groups, the median percent change was found for each modality rather than calculating effect size.

Until May 2007, there was no clinical scale to measure synkinesis. Sometimes the symptoms of synkinesis can be mild and might not require treatment. 0:00 / 15:20 NEW RAY OF HOPE FOR PEOPLE WITH SYNKINESIS 5,217 views Premiered May 2, 2021 VIDEO TITLE: SYNKINESIS CAN BE REVERSED! Synkinesis (pronounced sink-eye-nee-sis) means the development of linked or unwanted facial movements. J Plast Reconstr Aesthet Surg. The https:// ensures that you are connecting to the Synkinesis describes unwanted contractions of the muscles of the face during attempted movement. Bookshelf Chemodenervation articles were the most consistent in adverse event reporting; all studies commented on side effects. As synkinesis following peripheral nerve injury occurs so rarely, there is no precedent for identifying, understanding, or treating it. Sunderland Road, Chemodenervation is a simple, fast treatment that targets specific muscles. Synkinesis (pronounced sink-eye- nee -sis) means the development of linked or unwanted facial movements. Neurolysis has been shown to be effective in relieving synkinesis but only temporarily and unfortunately symptoms return much worse than originally. Most, but not all, patients will benefit from a multidisciplinary approach that includes facial therapy by an expert in facial physical/occupational therapy, speech language pathology, and plastic surgery of the face. Download our 'Questions for my Surgeon' form here. Synkinesis occurs when a desired facial movement is accompanied by another unwanted facial movement. Your treatment may involve a team approach that includes a physical therapist, occupational therapist, a neurologist (a specialist in conditions affecting the nervous system), or a physical medicine and rehabilitation physician. This causes weakness in voluntary chewing; also, facial movements such as blinking cause the muscles to contract. Disclosure: The authors have no financial interest to declare in relation to the content of this article. Biofeedback using mirrors or electromyography has been used both for the treatment and prevention of facial synkinesis. Front Neurol. Searches were completed in February 2018 and updated in May 2019; details are included in Appendix 1. Experimental research for treatment has been mostly focused on facial synkinesis due to its abundant prevalence compared to extra-ocular synkinesis. Patient-led, at-home schedules were better described. Plast Reconstr Surg. Synkinesis is characterized by abnormal sequencing of facial movements resulting in uncoordinated . Some patients who have previously had Bells palsy or other reversible forms of facial nerve injury may go on to develop synkinesis. In general, the involuntary movements of synkinesis only affect one side of the face because the damage that causes the condition typically affects one nerve or one side of the face. These aberrant branches can simultaneously innervate different subdivisions of the facial nerve.[3].
