Intelligent bell facial paralysis assessment: a facial recognition model using improved SSD network.

With the continuous progress of technology, the subject of life science plays an increasingly important role, among which the application of artificial intelligence in the medical field has attracted more and more attention. Bell facial palsy, a neurological ailment characterized by facial muscle weakness or paralysis, exerts a profound impact on patients' facial expressions and masticatory abilities, thereby inflicting considerable distress upon their overall quality of life and mental well-being. In this study, we designed a facial attribute recognition model specifically for individuals with Bell's facial palsy. The model utilizes an enhanced SSD network and scientific computing to perform a graded assessment of the patients' condition. By replacing the VGG network with a more efficient backbone, we improved the model's accuracy and significantly reduced its computational burden. The results show that the improved SSD network has an average precision of 87.9% in the classification of light, middle and severe facial palsy, and effectively performs the classification of patients with facial palsy, where scientific calculations also increase the precision of the classification. This is also one of the most significant contributions of this article, which provides intelligent means and objective data for future research on intelligent diagnosis and treatment as well as progressive rehabilitation.

Oral Health-Related Quality of Life in Rare Disorders of Congenital Facial Weakness.

Congenital facial weakness (CFW) encompasses a heterogenous set of rare disorders presenting with decreased facial movement from birth, secondary to impaired function of the facial musculature. The aim of the present study is to provide an analysis of subject-reported oral health-related quality of life (OHRQoL) in congenital facial weakness (CFW) disorders. Forty-four subjects with CFW and age- and sex- matched controls were enrolled in an Institutional Review Board (IRB)-approved study. Demographic data, medical and surgical history, comprehensive oral examination, and the Oral Health Impact Profile (OHIP-14) were obtained. Compared to unaffected controls, subjects with CFW had higher OHIP-14 scores overall (mean ± SD: 13.11 ± 8.11 vs. 4.46 ± 4.98, p < 0.0001) and within five of seven oral health domains, indicating decreased OHRQoL. Although subjects with Moebius syndrome (MBS) were noted to have higher OHIP-14 scores than those with Hereditary Congenital Facial Paresis (HCFP), there was no significant correlation in OHIP-14 score to age, sex, or specific diagnosis. An increase in OHIP-14 scores in subjects was detected in those who had undergone reanimation surgery. In conclusion, subjects with CFW had poorer OHRQoL compared to controls, and subjects with MBS had poorer OHRQoL than subjects with HCFP. This study provides better understanding of oral health care needs and quality of life in a CFW cohort and suggests that guidelines for dental treatment are required.

Evaluation of quality of life for patients with resolved facial nerve palsy.

OBJECTIVES: The quality of life (QOL) for patients with resolved facial nerve palsy has not been evaluated adequately. The objective of this study is to investigate QOL for patients with resolved facial nerve palsy. METHODS: Forty-seven patients with resolved facial nerve palsy were included and the patients' QOL was evaluated using the Facial Clinimetric Evaluation Scale (FaCE Scale). RESULTS: Twenty-two of the 47 patients (46.8%) with resolved facial nerve palsy showed impaired QOL, especially in terms of facial comfort and eye comfort. In 10 cases followed-up after the condition was judged to be resolved, the median scores for the FaCE scale at the time the condition was judged to be resolved and at the last visit were 65.5 and 72, respectively. The mean durations from the onset of the palsy to diagnosis of cure and to the last visit were 2.4 ± 1.6 and 4.3 ± 2.2 months, respectively. There was a significant improvement in QOL after the condition was judged to be resolved. CONCLUSION: There were discrepancies between QOL and facial movement as evaluated by physicians in patients in whom facial nerve palsy was resolved as in patients with non-cured facial nerve palsy. Patients' QOL continued to improve even after physicians judged the condition to be resolved and this result indicated that there were cases where improvement in QOL was delayed in comparison to improvement in facial movement.

Secondary dynamic midface reanimation with gracilis free muscle transfer after failed reconstruction attempt: A 15-year experience.

BACKGROUND: The quantitative outcome of secondary reanimation after a failed primary reconstruction attempt for facial paralysis is rarely reported in the literature. This study aimed to investigate the feasibility of secondary reanimation with gracilis free muscle transfer (GFMT) and whether this outcome is influenced by the primary reconstruction. METHODS: Twelve patients with previously failed static procedures (static group, n = 6), temporal muscle transfer (temporal transfer group, n = 2), and GFMT (GFMT group, n = 4) were all secondarily reanimated with GFMT. The clinical outcome was graded with the eFACE metric. The objective oral commissure excursion was measured with Emotrics, and the artificial intelligence software FaceReader evaluated the intensity score (IS) of emotional expression. RESULTS: The mean follow-up was 40 ± 27 months. The eFACE metric showed a statistically significant (p < 0.05) postoperative improvement in the dynamic and smile scores across all groups. In the GFMT group, oral commissure with smile (75.75 ± 20.43 points), oral commissure excursion while smiling with teeth showing (32.7 ± 4.35 mm), and the intensity of happiness emotion while smiling without teeth showing (IS of 0.37 ± 0.23) were significantly lower as compared with the static group postoperatively (98.83 ± 2.86 points, p = 0.038; 41.7 ± 4.35 mm, p = 0.025; IS 0.83 ± 0.16, p = 0.01). CONCLUSIONS: Our data suggest that secondary dynamic reconstruction with GFMT is feasible should the primary reconstruction fail. The secondary GFMT appears to improve the outcome of primary GFMT; however, the oral commissure excursion while smiling might be lower than that in patients who had static procedures as primary reconstruction.

Inability to move one's face dampens facial expression perception.

Humans rely heavily on facial expressions for social communication to convey their thoughts and emotions and to understand them in others. One prominent but controversial view is that humans learn to recognize the significance of facial expressions by mimicking the expressions of others. This view predicts that an inability to make facial expressions (e.g., facial paralysis) would result in reduced perceptual sensitivity to others' facial expressions. To test this hypothesis, we developed a diverse battery of sensitive emotion recognition tasks to characterize expression perception in individuals with Moebius Syndrome (MBS), a congenital neurological disorder that causes facial palsy. Using computer-based detection tasks we systematically assessed expression perception thresholds for static and dynamic face and body expressions. We found that while MBS individuals were able to perform challenging perceptual control tasks and body expression tasks, they were less efficient at extracting emotion from facial expressions, compared to matched controls. Exploratory analyses of fMRI data from a small group of MBS participants suggested potentially reduced engagement of the amygdala in MBS participants during expression processing relative to matched controls. Collectively, these results suggest a role for facial mimicry and consequent facial feedback and motor experience in the perception of others' facial expressions.

The psychological and psychosocial effects of facial paralysis: A review.

Facial nerve function is essential for a multitude of processes in the face, including facial movement; expression; and functions, such as eating, smiling, and blinking. When facial nerve function is disrupted, facial paralysis may occur and various complications for the patient may result. Much research has been conducted on the physical diagnosis, management, and treatment of facial paralysis. However, there is a lack of knowledge of the psychological and social effects of the condition. Patients may be at an increased risk for anxiety and depression, as well as negative self and social perceptions. This review analyzes the current literature on the various adverse psychological and psychosocial effects of facial paralysis, factors that may play a role, and treatment options that may help improve patients' quality of life.

Patient Perception of Education, Care Coordination, and Psychological Distress After Developing Facial Paralysis: A Qualitative Study.

Importance: The management of vestibular schwannoma may include observation, microsurgical resection, or radiation of a tumor near the facial nerve. Injury to the facial nerve can result in facial paralysis with major functional, social, and psychological sequelae, and the experiences of patients after paralysis are not well studied. Objective: To (1) identify patient preparedness for developing facial paralysis and how well their care is coordinated following its development and (2) present in their own words outcomes of facial paralysis in terms of physical health, emotional health, self-perception, and social interactions. Design, Setting, and Participants: A qualitative observational study was performed using semistructured interviews at a tertiary care academic medical center. Semistructured interviews were conducted between January 1, 2018, and June 30, 2019, with adults aged 25 to 70 years who developed facial paralysis after treatment for vestibular schwannoma. Data were analyzed from July 2019 to June 2020. Main Outcomes and Measures: Perceptions of the educational and emotional experiences of individuals who developed complete facial paralysis after surgical treatment of vestibular schwannoma. Results: Overall, 12 participants were interviewed (median age, 54 years [range, 25-70 years]; 11 were female). Saturation was achieved after 12 interviews, indicating that no further information could be elicited from additional interviews. Four major themes were identified: (1) lack of sufficient patient education about the diagnosis of facial paralysis; (2) lack of appropriate care coordination related to facial paralysis; (3) changes in physical and emotional health following facial paralysis; and (4) changes in social interactions and external support following facial paralysis. Conclusions and Relevance: It is well-known that patients with facial paralysis have reduced quality of life, severe psychological and emotional sequelae. However, little is currently done to help prepare patients for this undesirable outcome. In this qualitative study of facial paralysis, patients express, in their own words, their feeling that the education and management of facial paralysis by their clinicians was inadequate. Before patients undergo surgery, and certainly after injury to the facial nerve, clinicians should consider the patient's goals, preferences, and values to ensure that a comprehensive educational program and psychosocial support system are implemented. Facial reanimation research has not adequately captured these key patient factors associated with the quality of communication.

Influence of Subclinical Anxiety and Depression on Quality of Life and Perception of Facial Paralysis.

Introduction: Patients with facial paralysis have increased psychosocial distress, which affects overall quality of life (QOL). Objective: To evaluate the relationship between QOL and paralysis severity among patients with subclinical anxiety and/or depression. Methods: Patients with facial paralysis were screened for anxiety and depression using the Generalized Anxiety Disorder-2 and Patient Health Questionnaire-2 surveys. QOL scores (Facial Clinimetric Evaluation) and paralysis severity scores (House-Brackmann [HB] and Sunnybrook [SB]) were collected. Patients with a mental health diagnosis or treatment were excluded. Univariate and multivariate analyses and Pearson's correlations were performed after stratifying by anxiety and/or depression screenings. Results: Positive anxiety and depression screening rates were 25.78% and 22.66%, respectively. Patients screening positive had significantly worse QOL scores despite no difference in paralysis severity. QOL scores did not correlate with SB scores among patients who screened positive for depression. Conclusion: Patients screening positive for anxiety and/or depression demonstrated worse QOL, which did not correlate with paralysis severity suggesting that health care professionals should remain alert to mental health symptoms when QOL impairment is out of proportion with the severity of paralysis.

Psychological counselling in patients with a peripheral facial palsy: initial experience from an expert centre.

BACKGROUND: The aims of this pilot study were to evaluate the psychologist's role on the multidisciplinary team during peripheral facial palsy (PFP) patient care and to identify the potential predictors of anxiety and depressive symptoms/disorders in PFP patients. METHODS: Using the prospective non-controlled study design, PFP patients aged 18-75 years who presented to the Radboud Facial Palsy Expert Centre, the Netherlands, were enrolled during a 1-year interval. The main outcome variables were 1) anxiety and depression in relation to PFP using the Hospital Anxiety and Depression Scale (HADS) and 2) the outcome of psychological counselling in patients with a HADS score ≥ 8. RESULTS: A sample comprised 25 patients (68% females, 56% right-side PFP, 16% House-Brackmann scale I-II) with a mean age of 50 ± 14 years were referred to a psychologist. The proportion of patients with a HADS score ≥8, were 16 (64%) and 13 (52%), respectively. Especially, coping (in general or coping with the disease, 48%) and/or help with the choice of possible surgery (8.0%) were important reasons for counselling. In one case, a patient had chronic fatigue syndrome and was therefore referred to a psychological specialist centre. One patient was treated with acceptance and commitment therapy (ACT) with good results. CONCLUSIONS: Despite a small sample size and limited statistical analyses, the results of this study suggest that one-eighth of the PFP patients require psychological evaluation and treatments. This pilot study emphasises the important role of psychological screening and counselling in PFP patient care.

Psychological evaluation for patients with non-cured facial nerve palsy.

OBJECTIVE: The aim of the present study was to evaluate the psychological condition of patients with non-cured facial nerve palsy and to investigate whether their psychological condition is correlated with the degree of facial nerve palsy, synkinesis or quality of life. METHODS: Thirty patients with non-cured facial nerve palsy were enrolled in this study. Psychological conditions were evaluated by questionnaires including State-Trait Anxiety Inventory and Self-rating Depression Scale. RESULTS: Of the thirty patients with non-cured facial nerve palsy, 17 (56.7%) and 15 patients (50.0%) felt anxiety and depression, respectively. Although there were no significant correlations between their psychological condition and the degree of facial nerve palsy or that of sequelae, significant correlations were observed between psychological condition and the degree of QOL, especially in terms of social function. CONCLUSIONS AND SIGNIFICANCE: Disabilities associated with facial nerve palsy may be overlooked when evaluation is performed by physician-graded instruments alone. To resolve this problem, patients with non-cured facial nerve palsy should be evaluated by not only physician-graded tools but also patient-based assessment tools.

Psychometric Validation of the FACE-Q Craniofacial Module for Facial Nerve Paralysis.

Background: Systematic reviews have identified the need for a patient-reported outcome measure for facial nerve paralysis (FNP). The aim of this study was to determine the psychometric properties of FACE-Q Craniofacial module scales when used in a combined sample of children and older adults with FNP. Methods: Data were collected between December 2016 and December 2019. We conducted qualitative interviews with children and adults with FNP. FACE-Q data were collected from patients aged 8 years and older with FNP. Rasch measurement theory analysis was used to examine the reliability and validity of the relevant scales in the FNP sample. Results: Twenty-five patients provided 2052 qualitative codes related to appearance, physical, psychological, and social function. Many patient concerns were common across age. The field-test sample included 235 patients aged 8-81 years. Of the 13 scales examined, all 122 items had ordered thresholds and good item fit to the Rasch model. For 12 scales, person separation index values were ≥0.79 and Cronbach's alpha values were ≥0.82. The 13th scale's reliability values were ≥0.71. Conclusion: The FACE-Q Craniofacial module scales described in this study can be used to collect and compare evidence-based outcome data from children and adults with FNP.

Associations Between Clinician-Graded Facial Function and Patient-Reported Quality of Life in Adults With Peripheral Facial Palsy: A Systematic Review and Meta-analysis.

Importance: Understanding how the quality of life of adults (≥18 years) with peripheral facial palsy can be estimated using clinician measures of facial function and patient-reported variables might aid in counseling patients and in conducting research. Objectives: To analyze associations between clinician-graded facial function and patient-reported quality of life in adults with peripheral facial palsy, compare associations between facial function and the physical and social functions of quality of life, and examine factors that might influence the associations. Data Sources: A literature search was conducted in PubMed, Embase, CINAHL, Web of Science and PsycInfo on June 4, 2020, with no restrictions on the start date. Study Selection: Twenty-three studies reporting an association between clinician-graded facial function and patient-reported quality of life in adults with peripheral facial palsy were included. Facial function instruments included the House-Brackmann, Sunnybrook Facial Grading System, and electronic clinician-graded facial function assessment. Quality-of-life instruments included the Facial Disability Index and Facial Clinimetric Evaluation Scale. Data Extraction and Synthesis: Data extraction and qualitative synthesis were performed according to the Meta-analysis of Observational Studies in Epidemiology guidelines. Record screening, data extraction, and quality assessments were done by 2 researchers independently. Data were pooled using random-effects models. Main Outcomes and Measures: The main outcome was the association between facial function and quality of life, quantified by Pearson r, Spearman ρ, or regression analysis. Results: In total, 23 studies (3746 participants) were included. In the 21 studies that reported on the sex of the cohorts, there were 2073 women (57.3%). Mean or median age ranged from 21 to 64 years and mean or median duration of palsy ranged from newly diagnosed to 12 years. Bell palsy (n = 1397), benign tumor (n = 980), and infection (n = 257) were the most common etiologic factors. Pooled correlation coefficients were 0.424 (95% CI, 0.375-0.471) to 0.533 (95% CI, 0.447-0.610) between facial function and Facial Clinimetric Evaluation Scale total, 0.324 (95% CI, 0.128-0.495) to 0.397 (95% CI, 0.242-0.532) between facial function and Facial Clinimetric Evaluation Scale social function, 0.423 (95% CI, 0.322-0.514) to 0.605 (95% CI, -0.124-0.910) between facial function and Facial Disability Index physical function, and 0.166 (95% CI, 0.044-0.283) to 0.208 (95% CI, 0.031-0.373) between facial function and Facial Disability Index social function. Conclusions and Relevance: Associations noted in this systematic review and meta-analysis were overall low to moderate, suggesting that only a small part of quality of life is explained by facial function. Associations were higher between facial function and physical function than social function of quality of life.

The impact of radical parotidectomy with immediate facial nerve reconstruction: a quality-of-life measure.

OBJECTIVE: Immediate facial nerve reconstruction is the standard of care following radical parotidectomy; however, quality of life comparisons with those undergoing limited superficial parotidectomy without facial nerve sacrifice is lacking. METHOD: Patients who underwent parotidectomy were contacted to determine quality of life using the University of Washington Quality of Life and Parotidectomy Specific Quality of Life questionnaires. A total of 29 patients (15 in the radical parotidectomy and 14 in the limited superficial parotidectomy groups) completed and returned questionnaires. RESULTS: Using the University of Washington Quality of Life Questionnaire, similar quality of life was noted in both groups, with the radical parotidectomy group having significantly worse speech and taste scores. Using the Parotidectomy Specific Quality of Life Questionnaire, the radical parotidectomy group reported significantly worse speech, eye symptoms and eating issues. CONCLUSION: Those undergoing radical parotidectomy with reconstruction had comparable overall quality of life with the limited superficial parotidectomy group. The Parotidectomy Specific Quality of Life Questionnaire better identified subtle quality of life complaints. Eye and oral symptoms remain problematic, necessitating better rehabilitation and more focused reconstructive efforts.

Association between duration of peripheral facial palsy, severity, and age of the patient, and psychological distress.

BACKGROUND: Peripheral facial palsy (PFP) (paralysis) can be a devastating condition that has been shown to have associations with increased depression and worse quality of life. The aim of the present study is to better understand the complex association of psychological distress with the duration, severity, and age of patients with PFP. We hypothesize that a shorter duration of PFP is associated with higher levels of psychological distress. METHODS: Fifty-nine patients with PFP that existed longer than 3 months were included in this study. The Hospital Anxiety and Depression Scale (HADS) was used to assess the presence and severity of anxiety and depressions. Spearman's correlation analysis was used to determine correlation between psychological distress, duration, severity of the PFP, and age. RESULTS: Fifty-nine patients were included in this study, of whom 22 were male and 37 were female. The mean age was 55.6 ±â€¯14.6 years and mean duration of PFP from onset ranged from 3 months to 35 years (with a mean duration of 5.39 ±â€¯6.06 years). Twenty-eight patients had left-sided PFP, 30 patients had right-sided PFP, and one patient had bilateral PFP. The majority were caused by Bell's palsy (50.8%). In the group with a duration less than 5 years, there were five (12.8%) patients having a score between 11 and 15 (on HADS) compared to two (10%) patients in the group with a duration of 5 years or more(p = 0.04). CONCLUSION: There seems to be an association between moderate depression and duration of the PFP. Further studies need to substantiate our findings.

Early Outcomes in an Emerging Facial Nerve Center: The Oregon Health and Science University (OHSU) Experience.

OBJECTIVES: Nerve transfer (NT) and free gracilis muscle transfer (FGMT) are procedures for reanimation of the paralyzed face. Assessing the surgical outcomes of these procedures is imperative when evaluating the effectiveness of these interventions, especially when establishing a new center focused on the treatment of patients with facial paralysis. We desired to discuss the factors to consider when implementing a facial nerve center and the means by which the specialist can assess and analyze outcomes. METHODS: Patients with facial palsy secondary to multiple etiologies, including cerebellopontine angle tumors, head and neck carcinoma, and trauma, who underwent NT or FGMT between 2014 and 2019 were included. Primary outcomes were facial symmetry and smile excursion, calculated using FACE-gram and Emotrics software. Subjective quality of life outcomes, including the Facial Clinimetric Evaluation (FaCE) Scale and Synkinesis Assessment Questionnaire (SAQ), were also assessed. RESULTS: 14/22 NT and 6/6 FGMT patients met inclusion criteria having both pre-and postoperative photo documentation. NT increased oral commissure excursion from 0.4 mm (SD 5.3) to 2.9 mm (SD 6.8) (P = 0.05), and improved symmetry of excursion (P < 0.001) and angle (P < 0.001). FGMT increased oral commissure excursion from -1.4 mm (SD 3.9) to 2.1 mm (SD 3.7), (P = 0.02), and improved symmetry of excursion (P < 0.001). FaCE scores improved in NT patients postoperatively (P < 0.001). CONCLUSIONS: Measuring outcomes, critical analyses, and a multidisciplinary approach are necessary components when building a facial nerve center. At our emerging facial nerve center, we found NT and FGMT procedures improved smile excursion and symmetry, and improved QOL following NT in patients with facial palsy secondary to multiple etiologies.

Activity limitations and participation restrictions in patients with peripheral facial palsy: a cross-sectional study over a six-year period.

BACKGROUND: Peripheral facial palsy is a pathological condition caused by a wide range of etiologies. A damage of VII cranial nerve produces facial disfigurement and limitations in daily life activities, such as drinking, eating and speaking. As a consequence, patients may experience psychological distress and social isolation. To counsel and design a patient-tailored rehabilitation for patients affected by peripheral facial palsy, physical and social limitations should be considered. Moreover, the knowledge of factors associated with disability plays a key role in the early identification and adequate care of patients with higher risk to develop psychological distress and participation restrictions. AIM: To evaluate activity limitations, psychological distress and participation restrictions of patients affected by peripheral facial palsy seeking for rehabilitation and to identify individual and disease-specific factors associated to disability. DESIGN: Cross-sectional study. SETTING: Consultation hour dedicated to facial palsy patients in the outpatient clinic of a Rehabilitation Unit. POPULATION: One hundred eighty-six outpatients with recent or chronic peripheral facial palsy at the first assessment at our Rehabilitation Unit. METHODS: Using multiple linear regression models, we evaluated the association between the two subscales of Facial Disability Index (FDI) and the composite score of Sunnybrook Facial Grading System, as well as the association between the two FDI subscales and other clinical and demographic variables. RESULTS: Activity limitations correlate with the severity of palsy, while psychological distress and participation restrictions do not correlate with the neurological impairment. The correlation between the severity of palsy and both activity limitations and participation restrictions is influenced by palsy etiology. Activity limitations decrease with time from palsy onset, while psychological distress and participation restrictions are more severe in women. CONCLUSIONS: Beyond severity, also etiology, time from onset and gender influence disability after facial palsy. These factors should be considered in counselling and planning a patient-tailored multidisciplinary rehabilitative treatment. CLINICAL REHABILITATION IMPACT: Our study highlights the individual and pathology-associated factors related to activity limitations and participation restrictions in patients with peripheral facial palsy. These elements should be considered in the definition of a patient-tailored rehabilitative plan and in the organization of a multidisciplinary care.

Health-related quality of life in facial palsy: translation and validation of the Dutch version Facial Disability Index.

PURPOSE: Patient-reported outcome measures are essential in the evaluation of facial palsy. Aim of this study was to translate and validate the Facial Disability Index (FDI) for use in the Netherlands. METHODS: The FDI was translated into Dutch according to a forward-backward method. Construct validity was assessed by formulating 22 hypotheses regarding associations of FDI scores with the Facial Clinimetric Evaluation scale, the Synkinesis Assessment Questionnaire, the Short Form-12 and the Sunnybrook Facial Grading System. Validity was considered adequate if at least 75% (i.e. 17 out of 22) of the hypotheses were confirmed. Additionally, confirmatory factor analysis was performed. Cronbach's α was calculated as a measure of internal consistency. Participants were asked to fill out the FDI a second time after 2 weeks to analyse test-retest reliability. Lastly, smallest detectable change was calculated. RESULTS: In total, 19 hypotheses (86.4%) were confirmed. Confirmatory factor analysis showed acceptable fit for the two factor structure of the original FDI (root mean square error of approximation = 0.064, standardized root mean square residual = 0.081, comparative fit index = 0.925, Chi-square = 50.22 with 34 degrees of freedom). Internal consistency for the FDI physical function scale was good (α > 0.720). Internal consistency for the FDI social/well-being scale was slightly less (α > 0.574). Test-retest reliability for both scales was good (intraclass correlation coefficients > 0.786). Smallest detectable change at the level of the individual was 17.6 points for the physical function and 17.7 points for the social/well-being function, and at group level 1.9 points for both scales. CONCLUSION: The Dutch version FDI shows good psychometric properties. The relatively large values for individual smallest detectable change may limit clinical use. The translation and widespread use of the FDI in multiple languages can help to compare treatment results internationally.

A Systematic Review of the Psychosocial Adjustment of Children and Adolescents with Facial Palsy: The Impact of Moebius Syndrome.

INTRODUCTION: Facial palsy is often associated with impaired facial function and altered appearance. However, the literature with regards to the psychological adjustment of children and adolescents with facial palsy has not been systematically reviewed to date. This paper aimed to review all published research with regards to psychosocial adjustment for children and adolescents with facial palsy. METHODS: MEDLINE, CINAHL, Embase, PsychInfo and AMED databases were searched and data was extracted with regards to participant characteristics, study methodology, outcome measures used, psychosocial adjustment and study quality. RESULTS: Five studies were eligible for inclusion, all of which investigated psychosocial adjustment in participants with Moebius syndrome, a form of congenital facial palsy. Many parents reported their children to have greater social difficulties than general population norms, with difficulties potentially increasing with age. Other areas of psychosocial adjustment, including behaviour, anxiety and depression, were found to be more comparable to the general population. DISCUSSION: Children and adolescents with Moebius syndrome may experience social difficulties. However, they also demonstrate areas of resilience. Further research including individuals with facial palsy of other aetiologies is required in order to determine the psychosocial adjustment of children and adolescents with facial palsy.

A closer look at the paralyzed face; a narrative review of the neurobiological basis for functional and aesthetic appreciation between patients with a left and a right peripheral facial palsy.

BACKGROUND: The facial nerve or n. facialis (NVII) is the seventh cranial nerve and it is responsible for the innervation of the mimic muscles, the gustatory organ, and the secretomotor function to the salivary, lacrimal, nasal and palatine glands. Clinical presentation of Facial Palsy (FP) is characterized by unilateral facial asymmetry and may present with a change in taste, decreased saliva production, and dysarthria. A facial palsy has a notable effect on the facial appreciation by both the patient and the environment and also affects quality of life and emotional processing. There appear to be differences in the appreciation of people with a left and right facial palsy. PURPOSE OF THIS REVIEW: The purpose of the review is to give an overview of the anatomy of the facial nerve, neuro-anatomy of face processing, and hemispheric specialization and lateralization. Further,an overview is given of the clinical studies that translated the neuro-anatomical and neurobiological basis of these concepts into clinical studies. What this review adds: This review emphasizes the neurobiological evidence of differences in face processing between the left and right cerebral hemisphere, wherein it seems that the right hemisphere is superior in emotional processing. Several theories are proposed; 1) a familiarity hypothesis and 2) a left-right hemispheric specialization hypothesis. In clinical studies, promising evidence might indicate that, in patients with FP, there is indeed a difference in how left and right FP are perceived. This might give differences in decreased quality of life and finally in occurrence of depression. Further research must aim to substantiate these findings and determine the need for altering the standard therapeutic advice given to patients.
