Impact of early eyelid weight placement on the development of synkinesis and recovery in patients with idiopathic facial paralysis.

PURPOSE: Determine the impact of upper eyelid weight placement at 3 months post onset of idiopathic facial paralysis (IFP) on the recovery of facial function in patients with lagophthalmos. METHODS: This is a retrospective review of patients with incomplete recovery of IFP-defined as a Sunnybrook Facial Grading Scale (FGS) score of less than 100, 3 months after onset. Only patients with FGS and Facial Clinimetric Evaluation (FaCE) scores recorded at 3 and 12 months were included. Patients were categorized into 3 groups: Group A, lagophthalmos with eyelid weight placement; Group B, lagophthalmos without eyelid weight placement; Group C, complete eye closure (CEC) without eyelid weight placement. The eye comfort domain and composite score of the FaCE questionnaire were analyzed. Voluntary eye closure, synkinesis with eye closure, overall synkinesis and the composite score of the FGS were also analyzed. Paired two-tailed t-test was used to evaluate the data comparing the 3 and 12 month FaCE and FGS scores within and between the 3 groups. RESULTS: The change in composite FGS score significantly increased from month 3 to month 12 in Group A as compared to Group B (37 vs 4.25, P = 0.01). While Group A had significantly lower eye comfort (-12.5, P = 0.01), voluntary eye closure (-1.75, P = 0.05) and overall FGS scores (-28.75, P = 0.04) at 3 months compared to those in Group C, there were no differences between these two groups at 12 month follow-up. CONCLUSIONS: For patients with lagophthalmos at 3 months, early eyelid weight placement may lead to improved facial function at 12 months.

Mirror Book Therapy for the treatment of Idiopathic Facial Palsy.

OBJECTIVE: To determine the utility of treating facial palsy with mirror book therapy in conjunction with facial physical rehabilitation. METHODS: We randomly selected and reviewed the charts of 25 patients with idiopathic facial palsy. 10 of these patients received facial physical rehabilitation including manual therapy and postural exercises. 15 of these patients received mirror book therapy in conjunction with standard facial rehabilitation. Before and after treatment, patients in both groups were rated using the Facial Grading System (FGS) score, the Facial Disability Index--Physical (FDIP) score, and the Facial Disability Index--Social (FDIS) score. Differences in response to therapy were analyzed. RESULTS: Patients in the facial physical rehabilitation group without mirror book therapy group showed on average a 20.8% increase in the FGS score, a 19% increase in the FDIP score, and a 14.6% increase in the FDIS score. Patients in the mirror book therapy group showed an average of 24.9% increase in the Facial Grading System (FGS) score, a 21.6% increase in the Facial Disability Index--Physical (FDIP) score, and a 24.5% increase in the Facial Disability Index--Social (FDIS) score. CONCLUSION: The addition of mirror book therapy to standard facial rehabilitation treatments does significantly improve outcomes in the treatment of idiopathic facial palsy.

Association of Facial Paralysis With Perceptions of Personality and Physical Traits.

Importance: Facial paralysis has a significant effect on affect display, with the most notable deficit being patients' the inability to smile in the same way as those without paralysis. These impairments may result in undesirable judgements of personal qualities, thus leading to a significant social penalty in those who have the condition. Objective: To quantify the association of facial paralysis with the way smiling patients are perceived by others with respect to personality traits, attractiveness, and femininity or masculinity and to evaluate the potential association of facial palsy-related patient-reported outcome measures with how patients are perceived by others. Design, Setting, and Participants: This retrospective cross-sectional study used 20 images of smiling patients with facial paralysis evaluated between January 1, 2014, and December 31, 2016. Using photograph editing software, the photographs were edited to create a simulated nonparalysis smiling facial appearance. A total of 40 photographs were split into 4 groups of 10 photographs, each with 5 altered and 5 unaltered photographs. The surveys were designed such that altered and unaltered photographs of the same patient were not placed in the same survey to avoid recall bias. Anonymous raters used a 7-point Likert scale to rate their perception of each patient's personality traits (ie, aggressiveness, likeability, and trustworthiness), attractiveness, and femininity or masculinity based on photographs in their assigned survey. Raters were blinded to study intent. Scores from the Facial Clinimetric Evaluation questionnaire were included to assess self-perception. Data were analyzed from November 11, 2019, to February 20, 2020. Main Outcomes and Measures: Ratings of personality traits, attractiveness, and femininity or masculinity. Social function domain scores and overall scores were analyzed from the Facial Clinimetric Evaluation questionnaire. Results: This study included photographs of 20 patients with facial paralysis (mean [range] age, 54 [28-69] years; 15 [75%] women). A total of 122 respondents completed the survey (71 [61%] women). Most respondents were between the ages of 25 and 34 years (79 participants [65%]). Overall, smiling photos of patients with facial paralysis were perceived as significantly less likeable (difference, -0.29; 95% CI, -0.43 to -0.14), trustworthy (difference, -0.25; 95% CI, -0.39 to -0.11), attractive (difference, -0.47; 95% CI, -0.62 to -0.32), and feminine or masculine (difference, -0.21; 95% CI, -0.38 to -0.03) compared with their simulated preparalysis photographs. When analyzed by sex, smiling women with facial paralysis experienced lower ratings for likeability (difference, -0.34; 95% CI, -0.53 to -0.16), trustworthiness (difference, -0.24; 95% CI, -0.43 to -0.06), attractiveness (difference, -0.74; 95% CI, -0.94 to -0.55), and femininity (difference, -0.35; 95% CI, -0.58 to -0.13). However, smiling men with facial paralysis only received significantly lower ratings for likeability (difference, -0.24; 95% CI, -0.47 to -0.01) and trustworthiness (difference, -0.30; 95% CI, -0.53 to -0.07). As patients' self-reported social function and total Facial Clinimetric Evaluation scores increased, there was an increase in perceived trustworthiness (rs[480] = 0.11; P = .02) and attractiveness (rs[478] = 0.10; P = .04) scores by raters. Conclusions and Relevance: In this study, photographs of patients with facial paralysis received lower ratings for several personality and physical traits compared with digitally edited images with no facial paralysis. These findings suggest a social penalty associated with facial paralysis.

Reliability of grading of facial palsy using a video tutorial with synchronous video recording.

OBJECTIVE: To determine the intrarater, interrater, and retest reliability of facial nerve grading of patients with facial palsy (FP) using standardized videos recorded synchronously during a self-explanatory patient video tutorial. STUDY DESIGN: Prospective, observational study. METHODS: The automated videos from 10 patients with varying degrees of FP (5 acute, 5 chronic FP) and videos without tutorial from eight patients (all chronic FP) were rated by five novices and five experts according to the House-Brackmann grading system (HB), the Sunnybrook Grading System (SB), and the Facial Nerve Grading System 2.0 (FNGS 2.0). RESULTS: Intrarater reliability for the three grading systems was very high using the automated videos (intraclass correlation coefficient [ICC]; SB: ICC = 0.967; FNGS 2.0: ICC = 0.931; HB: ICC = 0.931). Interrater reliability was also high (SB: ICC = 0.921; FNGS 2.0: ICC = 0.837; HB: ICC = 0.736), but for HB Fleiss kappa (0.214) and Kendell W (0.231) was low. The interrater reliability was not different between novices and experts. Retest reliability was very high (SB: novices ICC = 0.979; experts ICC = 0.964; FNGS 2.0: novices ICC = 0.979; experts ICC = 0.969). The reliability of grading of chronic FP with SB was higher using automated videos with tutorial (ICC = 0.845) than without tutorial (ICC = 0.538). CONCLUSION: The reliability of the grading using the automated videos is excellent, especially for the SB grading. We recommend using this automated video tool regularly in clinical routine and for clinical studies. LEVEL OF EVIDENCE: 4 xsLaryngoscope, 129:2274-2279, 2019.

[Video Instruction for Synchronous Video Recording of Mimic Movement of Patients with Facial Palsy]. / Patienten-Instruktionsvideo mit synchroner Videoaufnahme von Gesichtsbewegungen bei Fazialisparese.

Background Photografy and video are necessary to record the severity of a facial palsy or to allow offline grading with a grading system. There is no international standard for the video recording urgently needed to allow a standardized comparison of different patient cohorts. Methods A video instruction was developed. The instruction was shown to the patient and presents several mimic movements. At the same time the patient is recorded while repeating the presented movement using commercial hardware. Facial movements were selected in such a way that it was afterwards possible to evaluate the recordings with standard grading systems (House-Brackmann, Sunnybrook, Stennert, Yanagihara) or even with (semi)automatic software. For quality control, the patients evaluated the instruction using a questionnaire. Results The video instruction takes 11 min and 05 and is divided in 3 parts: 1) Explanation of the procedure; 2) Foreplay and recreating of the facial movements; 3) Repeating of sentences to analyze the communication skills. So far 13 healthy subjects and 10 patients with acute or chronic facial palsy were recorded. All recordings could be assessed by the above mentioned grading systems. The instruction was rated as well explaining and easy to follow by healthy persons and patients. Discussion There is now a video instruction available for standardized recording of facial movement. This instruction is recommended for use in clinical routine and in clinical trials. This will allow a standardized comparison of patients within Germany and international patient cohorts.

Mirror book therapy for the treatment of idiopathic facial palsy.

We conducted a retrospective chart review to determine the effectiveness of treating idiopathic facial palsy with mirror book therapy in conjunction with facial physical rehabilitation. We compared outcomes in 15 patients who underwent mirror book therapy in addition to standard therapy with those of 10 patients who underwent standard rehabilitation therapy without the mirror book. Before and after treatment, patients in both groups were rated according to the Facial Grading System (FGS), the Facial Disability Index-Physical (FDIP), and the Facial Disability Index-Social (FDIS). Patients in the mirror therapy group had a mean increase of 24.9 in FGS score, 22.0 in FDIP score, and 25.0 in FDIS score, all of which represented statistically significant improvements over their pretreatment scores. Those who did not receive mirror book therapy had mean increases of 20.8, 19.0, 14.6, respectively; these, too, represented significant improvements over baseline, and thus there was no statistically significant difference in improvement between the two groups. Nevertheless, our results show that patients who used mirror book therapy in addition to standard facial rehabilitation therapy experienced significant improvements in the treatment of idiopathic facial palsy. While further studies are necessary to determine if it has a definitive, statistically significant advantage over standard therapy, we recommend adding this therapy to the rehabilitation program in view of its ease of use, low cost, and lack of side effects.
