The Effects of Telerehabilitation-Based Exercise Therapy on Motor and Non-Motor Clinical Outcomes in Adults With Facial Palsy: A Randomized Controlled Trial.

Recent case reports have emphasized the essential clinical contribution of telerehabilitation in the treatment of facial palsy. However, no randomized controlled trial has yet demonstrated the effects of telerehabilitation-based facial exercise therapy. Thus, we aimed to investigate the effectiveness of video exercise-based telerehabilitation on motor and non-motor clinical outcomes in adults with facial palsy. We conducted a randomized controlled trial with 40 peripheral facial palsy patients. Those in the experimental group (EG) received four weeks of telerehabilitation-based video exercises and routine care. Those in the control group (CG) received only routine care. All participants were evaluated with the Facial Disability Index (FDI), the Facial Clinimetric Evaluation Scale (FaCE), Short Form-12 (SF-12), the Hospital Anxiety and Depression Scale (HADS), the House-Brackmann Scale (H-B) and the Telemedicine Satisfaction and Usefulness Questionnaire (TSUQ), both before and after the interventions. Both groups demonstrated a significant improvement in FDI, FaCE, and SF-12 PCS scores (p < .05). In addition, there was a significant improvement only in EG on the SF-12 MCS score (p < .05), and there was a significant gain only in CG on the HADS-Depression score (p < .05). While these results provide a further contribution to our understanding of telerehabilitation benefits in mental health variables related to quality of life for facial palsy patients, we found no EG and CG differences on the physical components of treatment.

Acceptance and willingness of patients with chronic facial nerve palsy for an implantable device that assists with eye closure.

BACKGROUND: Patients with facial nerve palsy often experience lagophthalmos (incomplete eye closure), which can lead to exposure keratitis. The Bionic Lid Implant for Natural Eye Closure (BLINC) is a medical device designed to mimic the more natural blink kinetics than traditional lid loading techniques. AIMS: This study aimed to evaluate potential factors that might influence the design of the BLINC device and willingness of participant to undergo the implant placement surgery. METHODS: Patients attending a multidisciplinary facial nerve clinic were invited to complete a survey addressing patient acceptance of the BLINC device implantation. RESULTS: Seventy-two patients were mailed the survey, of which 50 returned completed surveys (69%). The most important factor identified by participants was the device function (81% ranked as very important) and the least important factor was cost (16% ranked as very important). Median acceptable device function time was 5 years (range 1-10 years). Ten participants (20%) indicated willingness to be the first to trial BLINC. Women were more likely to rate visual appearance as important (OR 3.32, CI 1.14-9.62, p = 0.028), and less likely to rate user friendliness as important (OR 0.16, CI 0.04-0.52, p = 0.0021). Older participants were more likely to rate the length of recovery period as important (OR 1.04, CI 1.01-1.08, p = 0.006). Participants with complete eye closure were less likely to be willing to trial the implant (OR 0.08, CI 0.00-0.53, p = 0.006, whilst patients with eye irritation were more willing to trial the implant (OR 7.20, CI 1.12-142, p = 0.036). CONCLUSION: Certain patient demographics impact patient aesthetic and functional preferences and the willingness to trial the BLINC device.

Combining early lower eyelid surgery with neuromuscular retraining for synkinesis prevention after facial palsy: the role of the eye in aberrant facial nerve regeneration.

Background: Facial synkinesis (FS) is a distressing sequela of facial palsy (FP) characterized by involuntary, simultaneous movements of facial muscles occurring during voluntary facial expressions. Treatment of synkinesis is challenging, and preventive methods are needed. Aim: This study evaluated the efficacy of physical facial nerve rehabilitation (PFNR) therapy alone vs. PNFR with eyelid surgery to correct lagophthalmos and prevent the onset of synkinesis. Methods: Twenty five outpatients were randomized to receive either PFNR alone (neuromuscular retraining and Kabat proprioceptive neuromuscular facilitation) or PNFR and early (90 days after FP onset) eyelid surgery (involving a conservative oculoplastic correction for lagophthalmos with epiphora or ectropion). Comprehensive otolaryngological assessments and Magnetic Resonance Imaging (MRI) were conducted. Synkinesis progression was measured using Another Disease Scale (ADS) at baseline, 3-, 6-, 12-, and 24-months post-treatment. The data were analyzed with ANOVA, τ-test, Chi-Square analyses. Results: Patients undergoing eyelid surgery with PFNR showed faster (p < 0.001) and better recovery of facial movements (p < 0.05) than patients receiving PFNR alone comparing T0 and T12 (p < 0.0001). No synkinesis were observed in the PFNR plus surgery group while 37% of patients in PFNR alone had synkinesis (p = 0.03). At 24 months, none of the patients in the surgery group presented synkinesis. Conclusion: Combining early surgical treatment of paralytic lagophthalmos or epiphora with PFNR accelerated functional recovery and reduced synkinesis in patients with FP compared to facial rehabilitation alone. Further investigations in larger populations with long-term follow-up are needed. Clinical trial registration: https://clinicaltrials.gov/study/NCT06538103, NCT06538103.

Job discrimination against applicants with the Moebius syndrome.

The main characteristic of Moebius syndrome is a lack of facial expressions, which involves stigmatization in many social contexts. We examined whether an applicant with this syndrome would be rated lower in personnel selection despite having equal qualifications. In two experiments, participants rated two applicants. Ratings of an applicant with Moebius syndrome were significantly lower when videos of job interviews had been watched without giving information about the syndrome. However, ratings did not differ when still images had been presented accompanied by an audio track or when participants were informed about Moebius syndrome ahead of the video. Discriminatory decisions in personnel selection could be reduced by educating about stigma, here, a neurologically caused lack of facial expressions.

Management of the Nasal Valve in Facial Paralysis.

Facial paralysis significantly impacts the form and function of patients. Assessment of the face in zones is important to ensure no functional area of the face is neglected. Nasal valve compromise in patients with facial paralysis, for example, is often overlooked yet should be addressed to correct nasal obstruction. In flaccid facial paralysis, inferomedial displacement of the alar base and lateral nasal sidewall insufficiency contribute to nasal valve compromise. For surgical candidates, static suspension of the nasal valve in a superolateral vector is an ideal technique to address the etiology of nasal obstruction in patients with facial paralysis.

Two novel compound heterozygous HOXB1 variants in congenital facial palsy: A case report and a brief review of the literature.

Hereditary congenital facial palsy (HCFP) is a medical condition caused by dysfunction of the seventh cranial nerve. HCFP is characterized by feeding difficulties and dysmorphic features in the orofacial region. In some cases hearing loss, strabismus, limb malformations, and musculoskeletal defects may be associated. There are three types of HCFP: HCFP3 (OMIM 614744) results from autosomal recessive pathogenic variants in the HOXB1 gene, while HCFP1 and 2 (OMIM 601471, 604185) are autosomal dominant, genetically less defined conditions. We report on a case of congenital bilateral facial palsy due to two novel compound heterozygous variants in the HOXB1 gene, found by exome sequencing (ES), in a child with facial nerve axonal neuropathy without evidence of nerve hypoplasia on neuroimaging. The results of this report suggest that in individuals with congenital facial paralysis and preserved ocular motor skills, with or without facial nerve hypoplasia and with confirmed facial nerve axonal neuropathy, HOXB1 variants and therefore a diagnosis of HCFP3 should be primarily considered.

Facia-Fix: Mobile Application for Bell's Palsy Diagnosis and Assessment using Computer Vision and Deep Learning.

Facial paralysis (FP) is a condition characterized by the inability to move some or all of the muscles on one or both sides of the face. Diagnosing FP presents challenges due to the limitations of traditional methods, which are time-consuming, uncomfortable for patients, and require specialized clinicians. Additionally, more advanced tools are often uncommonly available to all healthcare providers. Early and accurate detection of FP is crucial, as timely intervention can prevent long-term complications and improve patient outcomes. To address these challenges, our research introduces Facia-Fix, a mobile application for Bell's palsy diagnosis, integrating computer vision and deep learning techniques to provide real-time analysis of facial landmarks. The classification algorithms are trained on the publicly available YouTube FP (YFP) dataset, which is labeled using the House-Brackmann (HB) method, a standardized system for assessing the severity of FP. Different deep learning models were employed to classify the FP severity, such as MobileNet, CNN, MLP, VGG16, and Vision Transformer. The MobileNet model which uses transfer learning, achieved the highest performance (Accuracy: 0.9812, Precision: 0.9753, Recall: 0.9727, F1 Score: 0.974), establishing it as the optimal choice among the evaluated models. The innovation of this approach lies in its use of advanced deep learning models to provide accurate, objective, non-invasive and real-time comprehensive quantitative assessment of FP severity. Preliminary results highlight the potential of Facia-Fix to significantly improve the diagnostic and follow-up experiences for both clinicians and patients.

Evaluation of YouTube videos as a source of information on facial paralysis exercises.

BACKGROUND: YouTube has emerged as an important source for obtaining information regarding health issues. OBJECTIVE: The study aimed to assess the reliability and quality of facial paralysis exercise videos that are accessible on the YouTube platform. METHODS: The investigation was carried out on Youtube, utilizing the keyword "facial paralysis exercises". We listed the first 100 videos based on relevancy. The quality and reliability of the videos were assessed using DISCERN, the Journal of the American Medical Association (JAMA) Benchmark Criteria, the Global Quality Scale (GQS), and the Video Power Index (VPI). RESULTS: Out of 100 studies, we excluded 52 and included the remaining 48. The scores we obtained for the videos were as follows: DISCERN Quality (2.92±0.91), DISCERN Total (39.16±6.75), JAMA (2.09±0.55), and GQS (3.00±0.89). Our study also revealed that videos uploaded by healthcare professionals had significantly higher DISCERN total, JAMA and VPI scores compared to those uploaded by non-healthcare professionals (p = 0.018, 0.001 and 0.023, respectively). Additionally, we observed a positive and statistically significant correlation between the DISCERN quality score, total score, JAMA, and video features. CONCLUSION: The facial paralysis exercise videos were determined to be of medium to low quality. Higher-quality videos need to be produced.

Facial Paralysis in Otitis Media Due to Granulomatosis with Polyangiitis.

Granulomatosis with polyangiitis (GPA), formerly Wegener's granulomatosis, commonly presents primarily with otitis media and hearing loss, as well as upper and lower respiratory symptoms. However, facial nerve paralysis is a rare manifestation of this uncommon necrotizing vasculitis. We report a patient with facial paralysis accompanied by otitis media. In further studies, our patient was diagnosed with GPA, which was neglected before. In such a presentation, acute suppurative otitis media is the most likely cause of the facial paralysis, but GPA must also be considered, especially in cases with new-onset, painful serous otitis, acute otitis media, or pale granulation tissue in the middle ear, in adults with no previous history of Eustachian tube dysfunction.

Medullary infarction with central facial paralysis as the only symptom: a case report.

The anatomical structure of the medulla oblongata is complex, its nerve fibers are dense, and its blood vessels are complex. Clinical manifestations of ischemic damage to the medulla oblongata are therefore relatively diverse, and include vertigo, dysphagia, and dysarthria. Although facial paralysis may also occur, medullary infarction with facial paralysis as the first and only symptom is rare. Herein, we report a case of medullary infarction with ipsilateral central facial paralysis as the only symptom.

Through their eyes: Navigating life with limited eyelid closure in patients with Moebius syndrome.

BACKGROUND: Moebius syndrome (MoS), a rare congenital condition caused by the underdevelopment of the sixth and seventh cranial nerves, presents with uni- or bilateral facial paralysis and lateral gaze palsy. Those with MoS often have incomplete eyelid closure (lagophthalmos). This study aimed to investigate the experiences of individuals living with incomplete eyelid closure due to MoS. METHODS: Participants shared their experiences in semi-structured open-ended focus groups during the 2023 MoS Foundation Conference. Data were analyzed thematically using Nvivo. The Terzis and Bruno scoring system was used to grade participant eyelid closure (range: 1 being no eyelid closure with full scleral show to 5 being complete eyelid closure with no scleral show) and blink (from 1 being no blink to 5 being synchronous and complete blink present). Marginal reflex distances 1 and 2 (MRD1 and MRD2) were measured to grade for ptosis and lid retraction, respectively. RESULTS: Fifteen participants participated in two focus groups, comprising adults (n = 12) and adolescents (n = 3). All participants had lagophthalmos with some scleral show, ptosis, and lid retraction. The median eyelid closure score was 3 (incomplete eye closure with 1/3 scleral showing). Five key themes were identified: social stigma and misunderstanding, daily life impacts, seasonal exacerbations, different attitudes toward surgical intervention between adults and adolescents, and a prevailing sense of self-acceptance regarding their condition. CONCLUSION: Incomplete eyelid closure poses significant social challenges for individuals with MoS, especially around social encounters. Our findings show the importance of developing tailored communication tools to support those living with this facial difference.

Dynamic Repair Surgery for Late-Stage Facial Paralysis: Advances in Restoring Movement and Function.

Purpose: Facial paralysis results from congenital or acquired facial nerve damage, leading to significant cosmetic and functional deficits. Surgical resection of parotid and midface tumors can cause facial paralysis, necessitating effective treatment strategies. This review addresses the challenge of restoring movement and function in late-stage facial paralysis, focusing on dynamic repair techniques involving nerve and muscle transplantation. Methods: The review encompasses studies on dynamic repair surgery for late facial paralysis, including techniques such as local muscle flap with pedicle transfer, vascularized nerve flap with pedicle transfer, and multiple muscle flap procedures. A systematic literature search was conducted using PubMed, Web of Science, and Google Scholar, covering studies from 2000 to 2024. Keywords included "dynamic repair", "late-stage facial paralysis", "nerve and muscle transplantation", "muscle flap", and "tendon transposition". Included were clinical studies, systematic reviews, and meta-analyses reporting surgical outcomes. Exclusion criteria included studies with insufficient data and non-peer-reviewed articles. Results: Dynamic repair techniques involving nerve and muscle transplantation are essential for treating late-stage facial paralysis. Each surgical method has strengths and limitations. The masseter muscle flap demonstrates high success rates, although it can cause horizontal tension and jaw contour issues. The temporalis muscle flap is effective for smile restoration but may lead to temporal concavity. The gracilis muscle flap is widely used, especially with dual nerve innervation, showing high success in spontaneous smiles but requiring a longer recovery period. The latissimus dorsi flap is effective but can cause edema and shoulder issues. The serratus anterior free flap offers flexibility with precise vector positioning but may not achieve adequate lip elevation and can cause cheek swelling. Combined multi-flap surgeries provide more natural facial expressions but increase surgical complexity and require advanced microsurgical skills. Conclusions: Dual nerve innervation shows promise for restoring spontaneous smiles. One-stage surgery offers faster recovery and reduced financial burden. Comprehensive patient evaluation is crucial to select the most suitable surgical method. Dynamic repair techniques involving nerve and muscle transplantation provide effective solutions for restoring function and aesthetics in late-stage facial paralysis. Future research should focus on long-term outcomes, patient satisfaction, and standardizing surgical protocols to optimize treatment strategies.

Beyond the smile: a systematic review of diagnostic tools for peripheral facial paralysis.

BACKGROUND: Effective rehabilitation of peripheral facial paralysis (PFP) requires reliable assessment tools. This systematic review aimed to identify and validate instruments used in PFP rehabilitation, categorizing them according to the ICF framework. METHODS: A comprehensive search was conducted across PubMed, Cinahl, Web of Science, and Scopus up to April 2024. Observational analytical studies and one non-randomized controlled trial that validated tools for assessing PFP were included. RESULTS: Thirty-three studies were included, covering twenty different tools. Seventeen tools were related to the "Structure and Function" domain, while three addressed "Activity and Participation." The Sunnybrook and House-Brackmann scales were the most extensively studied. The Sunnybrook scale exhibited excellent intra- and inter-rater reproducibility and internal validity, making it suitable for clinical use. The House-Brackmann scale was user-friendly but had limitations in reproducibility and sensitivity to subtle differences, which newer versions like the FNGS 2.0 aimed to address. The FAME scale showed promise by reducing subjective scoring. Computerized tools, such as eFACE and A-FPG, and instruments for lip asymmetry and ocular involvement demonstrated potential but require further validation. The Facial Disability Index and the FaCE Scale were validated for assessing disability and participation restrictions. CONCLUSION: This review identified several validated tools for PFP assessment, with the Sunnybrook and House-Brackmann scales being the most reliable. While emerging tools and computerized programs show promise, they need further validation for routine clinical use. Integrating validated tools into clinical practice is essential for comprehensive assessment and effective rehabilitation of PFP.

A case series of low-level laser therapy treatment in patients with peripheral facial palsy.

BACKGROUND: Peripheral Facial Palsy (PFP) is a facial paralysis with various etiologies, including idiopathic causes (Bell's palsy), infections, trauma, and genetic factors. Traditional treatments involve antiviral medications, corticosteroids, and physiotherapy. However, new therapies, such as Low-Level Laser Therapy (LLLT), are emerging with promising results. METHODS: This case series reports on two patients with PFP treated with LLLT combined with Vitamin B1, B6, and B12 supplementation. The first case involved a 52-year-old female with PFP due to a viral infection. The second case was a 33-year-old male who developed PFP following a traumatic brain injury. Both patients received LLLT sessions every two weeks, targeting 10 points along the facial nerve pathway from the facial notch across the face. The laser device used was the Theraphy EC (DMC, Sao Carlos, SP, Brazil), with each point receiving 4 Joules of energy applied perpendicular to the skin after cleaning the face with water and soap to remove lipids that could interfere. The administration of Vitamin B was done using NEUROBIONTA tablets (Vitamin B1 + Vitamin B6 + Vitamin B12; Procter & Gamble, Santiago, Chile) with one tablet taken daily for 30 days. RESULTS: After six to seven sessions, both patients showed significant improvement in facial muscle function and overall facial symmetry. In the first case, improvements were noted in muscle tonicity and facial movements, with the patient reporting reduced facial disfigurement. In the second case, notable recovery in facial mobility and symmetry was observed, with the patient experiencing decreased paresthesia and restored muscle functionality. CONCLUSION: These findings suggest that LLLT, combined with Vitamin B1, B6, and B12 supplementation, may effectively improve facial muscle function and symmetry in PFP patients. The non-invasive nature and ease of application make LLLT a viable option for PFP treatment. Further studies with larger sample sizes and standardized protocols are necessary to confirm these results and establish LLLT as a standard treatment for PFP.

[Clinical observation on acupuncture at infusion points of "four seas" on refractory peripheral facial paralysis].

OBJECTIVE: To observe the clinical effect of acupuncture at the infusion points of "four seas" for refractory peripheral facial paralysis on the basis of conventional acupuncture. METHODS: A total of 52 patients with refractory peripheral facial paralysis were randomized into an observation group (26 cases, 2 cases dropped out) and a control group (26 cases, 1 case dropped out). On the basis of conventional acupuncture (Yintang [GV 24+] and Yangbai [GB 14], Dicang [ST 4] at affected side, etc.), acupuncture at the infusion points of "four seas", i.e. Baihui (GV 20), Dazhui (GV 14) and bilateral Shangjuxu (ST 37), Xiajuxu (ST 39), Zusanli (ST 36), was delivered in the observation group. On the basis of conventional acupuncture, shallow acupuncture was applied at corresponding non-meridian and non-acupoint points of the infusion points of "four seas" in the control group. The needles were maintained for 30 min, the treatment was given once every other day, 3 times a week for 4 weeks in the two groups. Before and after treatment, the House-Brackmann (H-B) facial nerve grading and the dynamic view score of the facial nerve function scoring system were observed, and the clinical efficacy was evaluated after treatment in the two groups. RESULTS: After treatment, the H-B facial nerve grading was improved compared with that before treatment in the two groups (P<0.05), and the grading in the observation group was superior to that in the control group (P<0.05); the dynamic view scores of the facial nerve function scoring system were increased compared with those before treatment in the two groups (P<0.05), and the score in the observation group was higher than that in the control group (P<0.05). The total effective rate was 91.7% (22/24) in the observation group, and that in the control group was 84.0% (21/25), there was no significant difference in the total effective rate between the two groups (P>0.05). The cure rate was 62.5% (15/24) in the observation group, which was higher than 20.0% (5/25) in the control group (P<0.05). CONCLUSION: On the basis of conventional acupuncture, acupuncture at infusion points of "four seas" can effectively treat refractory peripheral facial paralysis, improve the facial nerve function and increase the cure rate.

Optimization of the automated Sunnybrook Facial Grading System - Improving the reliability of a deep learning network with facial landmarks.

OBJECTIVE: The Sunnybrook Facial Grading System (SFGS) is a well-established grading system to assess the severity and progression of a unilateral facial palsy. The automation of the SFGS makes the SFGS more accessible for researchers, students, clinicians in training, or other untrained co-workers and could be implemented in an eHealth environment. This study investigated the impact on the reliability of the automated SFGS by adding a facial landmark layer in a previously developed convolutional neural network (CNN). METHODS: An existing dataset of 116 patients with a unilateral peripheral facial palsy and 9 healthy subjects performing the SFGS poses was used to train a CNN with a newly added facial landmark layer. A separate model was trained for each of the 13 elements of the SFGS and then used to calculate the SFGS subscores and composite score. The intra-class coefficient of the automated grading system was calculated based on three clinicians experienced in the grading of facial palsy. RESULTS: The inter-rater reliability of the CNN with the additional facial landmarks increased in performance for all composite scores compared to the previous model. The intra-class coefficient for the composite SFGS score increased from 0.87 to 0.91, the resting symmetry subscore increased from 0.45 to 0.62, the symmetry of voluntary movement subscore increased from 0.89 to 0.92, and the synkinesis subscore increased from 0.75 to 0.78. CONCLUSION: The integration of a facial landmark layer into the CNN significantly improved the reliability of the automated SFGS, reaching a performance level comparable to human observers. These results were attained without increasing the dataset underscoring the impact of incorporating facial landmarks into a CNN. These findings indicate that the automated SFGS with facial landmarks is a reliable tool for assessing patients with a unilateral peripheral facial palsy and is applicable in an eHealth environment.

Effect of modified facial paralysis rehabilitation nursing on patients with facial paralysis after vestibular schwannoma surgery.

Background and objective: After vestibular schwannoma (VS) surgery, some patients exhibit different degrees of peripheral facial paralysis, which can seriously affect their quality of life. The recovery of facial nerve function after surgery typically takes a considerable amount of time; therefore, the recovery of facial nerve function depends mainly on the rehabilitation treatment and nursing after discharge. In the past, we implemented conventional paralysis rehabilitation nursing program for patients with facial paralysis due to VS surgery. However, several patients with facial paralysis have bad compliance and do not achieve ideal facial nerve function recovery. Therefore, this study aimed to investigate whether modified facial paralysis rehabilitation nursing improves the effectiveness of rehabilitation of facial paralysis after VS surgery by analysing the clinical data of patients. Methods: We screened the patients with facial paralysis after VS surgery from December 2019 to May 2023. The patients were divided into the conventional and modified groups based on the different nursing programs (conventional vs. modified facial paralysis rehabilitation nursing program) to compare the differences in facial nerve function, quality of life of patients, and compliance of rehabilitation between the two groups. Results: We analysed 128 patients with facial paralysis after VS surgery who met the inclusion and exclusion criteria; 65 and 63 patients in the conventional and modified group, respectively. The number of patients in the modified group with House-Brackmann grade changes >0 in facial nerve function was significantly higher than that in the conventional group 3 months after surgery (82.5 % vs 63.1 %, p = 0.01). Except for the lacrimal control score, the mean scores of the Chinese version of the FaCE scale were significantly higher in the modified group than those in the conventional group at 1 and 3 months postoperatively. Conclusions: The modified facial paralysis rehabilitation nursing, i.e., integrated use of facial expressive muscle exercises and facial massage with video-assisted education, substantially improved the facial nerve function, quality of life, and compliance of rehabilitation nursing of patients with facial paralysis after VS surgery.

Chemodenervation is Associated With Reduced Mental Health Disorders in Patients With Synkinesis.

OBJECTIVE: To compare the prevalence of mental health disorders in individuals with facial synkinesis, facial paralysis alone, and the general population. STUDY DESIGN: Retrospective cohort. SETTING: Eighty-two health care organizations across the United States. METHODS: The TriNetX Research Network was queried from 2011 to 2021 for patients with facial paralysis without synkinesis, facial paralysis and documented synkinesis, and controls, matched for age, sex, race, and ethnicity. Cases included infectious, iatrogenic, or idiopathic facial paralysis. Patients with pre-existing depression or anxiety were excluded. Two-year rates of newly diagnosed depression, anxiety, and mental health prescriptions were compared. RESULTS: Among 127,573 patients with facial paralysis, 92.5% (n = 117,976) had facial paralysis alone, and 7.5% (n = 9597) also had documented synkinesis. Compared to controls, patients with facial paralysis alone had increased risks of new depression (8.9% vs 7.3%, P < .001) and anxiety (10.1% vs 9.6%, P < .001), with higher mental health medication rates (16.6% vs 13.1%, P < .001). Patients with documented synkinesis, in comparison to controls, had the highest risks of depression (19.8% vs 8.6%, P < .001), anxiety (20.5% vs 10.5%, P < .001), and prescriptions (28.1% vs 15.8%, P < .001). The 27.8% (n = 2669) of synkinetic patients treated with chemodenervation had lower rates of depression (8.5% vs 23.5%, P < .001), anxiety (9.0% vs 23.8%, P < .001), and prescriptions (21.6% vs 30.0%, P < .001) compared to synkinetic patients who were not. CONCLUSION: Facial paralysis, particularly synkinesis, is linked to increased mental health disorders. Integrating mental health screening and treatment into a comprehensive approach is crucial. Chemodenervation is associated with decreased mental health disorders in synkinesis, highlighting its therapeutic potential.
