Three-dimensional objective evaluation of facial palsy and follow-up of recovery with a handheld scanner.

BACKGROUND: Clinicians need accurate, reproducible, fast, and cost-effective grading systems to determine facial functions. There is currently no internationally accepted objective method to report the loss of function at the onset of facial paralysis and subsequent recovery. Our study aimed to test a three-dimensional handheld light scanner's efficacy for grading facial paralysis and monitoring recovery. METHODS: Sixty-one healthy volunteers (28 men and 33 women) aged between 20 and 75 years (mean 36.4 ± 11.9 years old) and 22 patients with facial palsy (10 male and 12 female patients) aged between 12 and 77 years (mean 47.6 ± 19.7 years old) were included in the study. The healthy individuals' and patients' facial scans were performed with a three-dimensional handheld scanner during different facial expressions at 3-month intervals. The asymmetry and intensity degree of each facial expression were determined in terms of the root mean square. RESULTS: After facial paralysis, a significant larger asymmetry value (1.2 ± 0.4 mm vs. 2.0 ± 0.8 mm and p<0.05) was determined as compared to the control group, while a significant smaller intensity value (2.3 ± 1.2 mm vs. 1.7 ± 0.9 mm and p<0.05) was observed. At the end of 3 months, both parameters showed a tendency to recover. CONCLUSION: Our findings suggest that three-dimensional morphological analyses may be an effective method to grade facial palsy. However, our data need to be confirmed by larger cohort size and more extended follow-up periods.

The digital doctor: telemedicine in facial plastic surgery.

PURPOSE OF REVIEW: In the setting of the COVID-19 global pandemic, the demand for and use of telemedicine has surged in facial plastic and reconstructive surgery. This review aims to objectively review and summarize the existing evidence for the use of telemedicine within facial plastic surgery. RECENT FINDINGS: Telemedicine has been successfully implemented among subsets of facial plastic surgery patients, with high patient and provider satisfaction. Although the technology to facilitate telemedicine exists and preliminary studies demonstrate promise, multiple technological, financial, and medical barriers may persist in the postpandemic era. SUMMARY: Telemedicine will likely continue to grow and expand within facial plastic surgery moving forward, and we should continue to critically evaluate patient selection, access to care, and strategies for effective implementation to enhance current clinical practices.

Validation of the Turkish version of the Sunnybrook facial grading system

Background/aim: To adapt the Sunnybrook facial grading system (SFGS) into Turkish and perform validation and reliability studies on the Turkish version. Materials and Methods: The original English version of the SFGS was translated into Turkish by performing a linguistic validity study based on international standards. The evaluators comprised 6 physicians. Evaluations were performed twice independently using the video recordings of 65 facial palsy patients. Synchronously, the House-Brackman facial grading system (HBFGS) was filled out to display concurrent validity. The intraclass correlation coefficient (ICC) and Cronbach's alpha was used for the examination of the inter- and intra-rater reliability. As another indication of reliability, the generalizability (G) was also examined. Results: The ICC for the inter-rater reliability for resting symmetry, symmetry of voluntary movement, synkinesis, and the composite score, which are 4 components of the SFGS, were determined, respectively, as 0.822, 0.956, 0.606, and 0.957 for the first evaluation, and 0.805, 0.965, 0.584, and 0.965 for the second evaluation. For the intra-rater reliability, the ICC were determined as 0.842, 0.956, 0.794, and 0.937, while the Cronbach's alpha coefficients were determined as 0.809, 0.956, 0.792, and 0.948, respectively. The G coefficient was determined as G = 0.772. For the concurrent validity, a strong correlation was found between the SFGS and HBFGS scores. Conclusion: The present study adapted the SFGS into Turkish, and demonstrated that the adapted scale was valid and reliable. The Turkish version can be used for the evaluation of facial palsy, the follow-up of treatment efficiency, and standardization in reporting outcomes with the international literature.

The spectrum of facial palsy: The MEEI facial palsy photo and video standard set.

OBJECTIVES: Facial palsy causes variable facial disfigurement ranging from subtle asymmetry to crippling deformity. There is no existing standard database to serve as a resource for facial palsy education and research. We present a standardized set of facial photographs and videos representing the entire spectrum of flaccid and nonflaccid (aberrantly regenerated or synkinetic) facial palsy. To demonstrate the utility of the dataset, we describe the relationship between level of facial function and perceived emotion expression as determined by an automated emotion detection, machine learning-based algorithm. METHODS: Photographs and videos of patients with both flaccid and nonflaccid facial palsy were prospectively gathered. The degree of facial palsy was quantified using eFACE, House-Brackmann, and Sunnybrook scales. Perceived emotion during a standard video of facial movements was determined using an automated, machine learning algorithm. RESULTS: Sixty participants were enrolled and categorized by eFACE score across the range of facial function. Patients with complete flaccid facial palsy (eFACE <60) had a significant loss of perceived joy compared to the nonflaccid and normal groups. Additionally, patients with only moderate flaccid and nonflaccid facial palsy had a significant increase in perceived negative emotion (contempt) when compared to the normal group. CONCLUSION: We provide this open-source database to assist in comparing current and future scales of facial function as well as facilitate comprehensive investigation of the entire spectrum of facial palsy. The automated machine learning-based algorithm detected negative emotions at moderate levels of facial palsy and suggested a threshold severity of flaccid facial palsy beyond which joy was not perceived. LEVEL OF EVIDENCE: NA Laryngoscope, 130:32-37, 2020.

Sequelae of Facial Palsy: A Comprehensive Treatment.

LEARNING OBJECTIVES: After studying this article, the participant should be able to: 1. Identify the different types of facial paralysis sequelae and define the several medical and surgical techniques commonly available today. 2. Develop a surgical plan to restore symmetry of the face at rest and in dynamic expressions and manage the patient during smile rehabilitation after dynamic smile reanimation with regional or free muscle transfer. 3. Understand the different types of facial paralysis sequelae and know the several medical and surgical techniques commonly available today. 4. Establish a comprehensive treatment plan to restore symmetry of the face at rest and in dynamic expressions and support the patient during smile rehabilitation after dynamic smile reanimation with regional or free muscle transfer. SUMMARY: Sequelae of facial palsy have a negative impact on the cosmetic aspect and functions of the face. They bear severe consequences for patients with regard to their body image and social relationships. There are numerous medical and surgical treatments that should be proposed to patients to achieve comprehensive facial symmetry. The key to an adapted therapeutic choice, to achieve the best outcomes for patients, is to perform a comprehensive evaluation of the paralyzed face and have broad knowledge of the several techniques described over time in the literature. The patient should be informed of the different therapeutic alternatives, their implications, and their limits. With this article, readers will be able to accurately diagnose the different types of facial paralysis sequelae to develop a surgical plan adapted to each case to restore symmetry at rest and in motion.

Automated objective and marker-free facial grading using photographs of patients with facial palsy.

PURPOSE: An automated, objective, fast and simple classification system for the grading of facial palsy (FP) is lacking. METHODS: An observational single center study was performed. 4572 photographs of 233 patients with unilateral peripheral FP were subjectively rated and automatically analyzed applying a machine learning approach including Supervised Descent Method. This allowed an automated grading of all photographs according to House-Brackmann grading scale (HB), Sunnybrook grading system (SB), and Stennert index (SI). RESULTS: Median time to first assessment was 6 days after onset. At first examination, the median objective HB, total SB, and total SI were grade 3, 45, and 5, respectively. The best correlation between subjective and objective grading was seen for SB and SI movement score (r = 0.746; r = 0.732, respectively). No agreement was found between subjective and objective HB grading [Test for symmetry 80.61, df = 15, p < 0.001, weighted kappa = - 0.0105; 95% confidence interval (CI) = - 0.0542 to 0.0331; p = 0.6541]. Also no agreement was found between subjective and objective total SI (test for symmetry 166.37, df = 55, p < 0.001) although there was a nonzero weighted kappa = 0.2670; CI 0.2154-0.3186; p < 0.0001). Based on a multinomial logistic regression the probability for higher scores was higher for subjective compared to objective SI (OR 1.608; CI 1.202-2.150; p = 0.0014). The best agreement was seen between subjective and objective SB (ICC = 0.34645). CONCLUSIONS: Automated Sunnybrook grading delivered with fair agreement fast and objective global and regional data on facial motor function for use in clinical routine and clinical trials.

Evaluation of Yanagihara facial nerve grading system based on a muscle fiber analysis of human facial muscles.

PURPOSE: We morphometrically analyzed human facial muscles, and evaluated the Yanagihara facial nerve grading system using our data. METHODS: We used 15 types of human facial muscle, 2 types of masticatory muscle and 2 types of skeletal muscle. The materials were obtained from 11 Japanese male cadavers aged 43-86 years. We counted the muscle fibers and measured the transverse area of the muscle fibers (TAMF), and then calculated the number of muscle fibers (NMF) per mm2 and the average TAMF. RESULTS: We found a significant correlation between average TAMF and NMF (r = - 0.70; p < 0.01). We classified facial muscles into three types based on the correlational results. Type A had a low average TAMF and high NMF. Type C had a high average TAMF and low NMF. Masticatory and skeletal muscles were characterized as Type C. Type B was intermediate between Types A and C. CONCLUSIONS: Pathological changes in the facial muscles in facial nerve palsy seem to vary according to the type of facial muscle, because each facial muscle has a unique fiber-type composition. As the nine discrete facial expressive states evaluated in the Yanagihara system involve all three facial muscle types of our classification, the Yanagihara system is an outstanding system for grading facial nerve palsy in terms of the facial muscle morphology.

paraFaceTest: an ensemble of regression tree-based facial features extraction for efficient facial paralysis classification.

BACKGROUND: Facial paralysis (FP) is a neuromotor dysfunction that losses voluntary muscles movement in one side of the human face. As the face is the basic means of social interactions and emotional expressions among humans, individuals afflicted can often be introverted and may develop psychological distress, which can be even more severe than the physical disability. This paper addresses the problem of objective facial paralysis evaluation. METHODS: We present a novel approach for objective facial paralysis evaluation and classification, which is crucial for deciding the medical treatment scheme. For FP classification, in particular, we proposed a method based on the ensemble of regression trees to efficiently extract facial salient points and detect iris or sclera boundaries. We also employ 2nd degree polynomial of parabolic function to improve Daugman's algorithm for detecting occluded iris boundaries, thereby allowing us to efficiently get the area of the iris. The symmetry score of each face is measured by calculating the ratio of both iris area and the distances between the key points in both sides of the face. We build a model by employing hybrid classifier that discriminates healthy from unhealthy subjects and performs FP classification. RESULTS: Objective analysis was conducted to evaluate the performance of the proposed method. As we explore the effect of data augmentation using publicly available datasets of facial expressions, experiments reveal that the proposed approach demonstrates efficiency. CONCLUSIONS: Extraction of iris and facial salient points on images based on ensemble of regression trees along with our hybrid classifier (classification tree plus regularized logistic regression) provides a more improved way of addressing FP classification problem. It addresses the common limiting factor introduced in the previous works, i.e. having the greater sensitivity to subjects exposed to peculiar facial images, whereby improper identification of initial evolving curve for facial feature segmentation results to inaccurate facial feature extraction. Leveraging ensemble of regression trees provides accurate salient points extraction, which is crucial for revealing the significant difference between the healthy and the palsy side when performing different facial expressions.

Insulina tópica en queratopatía neurotrófica tras resección de neurinoma del acústico / Topical insulin in neurotrophic keratopathy after resection of acoustic neuroma

Caso clínico: Una paciente con antecedente de resección quirúrgica de un neurinoma del acústico presentó compromiso tanto del nervio facial como del nervio trigémino izquierdos. Inicialmente consultó por queratitis de exposición, pero 2 semanas después presentó una queratitis infecciosa. Tras la toma de la muestra corneal cursó con un defecto epitelial persistente, que no respondió al manejo médico. Se indicó insulina tópica con lo que se evidenció disminución del área de la lesión en los siguientes 5 días. Se colocó además, en ese momento, una lente de contacto terapéutica y, finalmente, 2 semanas después de haberse iniciado la insulina, el defecto epitelial cerró por completo. Discusión: Se trata de un caso complejo por la confluencia de parálisis facial, queratitis neurotrófica y queratitis infecciosa, que finalmente tuvo un resultado exitoso. La insulina tópica puede ser una terapia coadyuvante efectiva en casos de úlceras neurotróficas que no respondan a la terapia convencional

Case report: A patient with a history of surgical resection of an acoustic neuroma presented with involvement of both the left facial nerve and the left trigeminal nerve. She initially consulted for exposure keratitis, but two weeks later presented with an infectious keratitis. After taking the corneal sample, she presented with persistent epithelial defect, which did not respond to medical management. Topical insulin was indicated, and a decrease in the area of the lesion was seen in the following 5 days. A therapeutic contact lens was also placed at that time and finally, two weeks after the initiation of insulin, the epithelial defect completely closed. Discussion: This was a complex case due to the confluence of facial paralysis, neurotrophic keratitis, and infectious keratitis, which finally had a successful outcome. Topical insulin can be an effective adjuvant therapy in cases of neurotrophic ulcers that do not respond to standard therapy

The association between paralytic side and health-related quality of life in facial palsy: a cross-sectional study of the Korea National Health and Nutrition Examination Survey (2008-2012).

BACKGROUND: Facial palsy is known to have correlations with low level of quality of life. However, little is known about the association between preference based health-related quality of life (HRQoL) and paralytic side of facial palsy. METHODS: This study used Korea National Health and Nutrition Examination Survey (KNHANES, 2008-2012) data, only when the facial palsy examination had been included in the survey contents. Hierarchical regression analyses were used to obtain optimal regression coefficients in the association between paralytic side of the facial palsy and HRQoL measured by EuroQoL-5 Dimension (EQ-5D). We also analyzed the association between the deteriorated domains of EQ-5D and facial palsy in both subgroups by using multiple logistic regression models. RESULTS: We included the data of 28,106 participants aged ≥19 years who were examined as facial palsy according to House-Brackmann score and completed EQ-5D questionnaire in KNHANES 2008-2012. The mean EQ-5D score was significantly low and percentages of deteriorated numbers in its domains were significantly high in facial palsy group. CONCLUSIONS: These results show that, after adjusting for confounding variables, left facial palsy is associated with impaired HRQoL compared with right-sided palsy. Among the domains of EQ-5D, only 'self-care' domain was directly affected by the disease in left facial palsy patients. These findings could be used in developing model and conducting analyses of economic evaluation about facial palsy interventions.

Surgery for post-traumatic facial paralysis: are we overdoing it?

PURPOSE: Early facial nerve decompression is recommended for cases of post-traumatic facial palsy on the basis of ENoG with degeneration > 95%. There is still a dispute in the literature concerning the role and timing of surgery versus conservative treatment in such cases. This study has been planned to evaluate the outcome of conservative management in traumatic facial paralysis with regard to type of trauma, onset, and electrodiagnostic tests. METHODS: A prospective cohort study included 39 patients with post-traumatic facial palsy. All patients underwent ENoG, nerve stimulation test, HRCT temporal bone and Schirmer's test. The patients received intravenous methylprednisolone 1 gm/day for 5 days or oral prednisolone 1 mg/kg in tapering doses for 3 weeks. Follow-up was done at 4, 12 and 24 weeks after the treatment. Surgical exploration was limited to patients showing no improvement after 12 weeks. Facial nerve function was evaluated by the HBFNS and FEMA grading systems. RESULTS: Among the 39 patients in the study [5 women and 34 men; mean (SD) age, 33.5 (11.37) years], facial nerve recovery with conservative treatment alone was noted in 31 patients. The first signs of clinical recovery were noted in 27 patients by 4 weeks, in 31 patients by 12 weeks. Seven patients required surgical exploration. At 24 weeks, 31 patients recovered to House-Brackmann grade I/III and 1 patient to grade IV. 19 of 26 patients with longitudinal fractures had grade I/III recovery, whereas all 6 patients with transverse fracture recovered on conservative treatment. CONCLUSIONS: Patients with incomplete facial palsy are candidates for conservative management. It is justified to try conservative management in patients with complete facial paralysis for up to 3 months even in cases where ENoG and NET suggest poor prognosis. The presence of sensorineural hearing loss or transverse fracture at presentation does not suggest a poor prognosis for improvement.

A General Approach to Facial Palsy.

Management of facial palsy can be daunting. This article presents a conceptual framework for classification and therapeutic management of facial palsy.

[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.

[Validation of the German Version of the Sunnybrook Facial Grading System]. / Validierung einer Deutschen Version des Sunnybrook Facial Grading Systems.

Background: The Sunnybrook facial grading system (SFGS) is frequently applied to evaluate facial function in patients with facial palsy, but still now there is no validated German version of this evaluation sheet. Methods: The original English version of the SFGS was translated and validated in accordance with international standards. The interrater reliability from 5 raters (speech therapy students) and the intrarater reliability from repeated ratings at 2 time points using video tapes of 18 patients with different types of facial palsy were analyzed by calculating the intraclass correlation coefficient (ICC) and other reliability measures. Results: ICC for the interrater reliability for the 4 components of the SFGS, resting symmetry, symmetry during voluntary movements, synkinesis, and the composite score were ICC 0.845; 0.903; 0.731 and 0.918, respectively, for the first evaluation and ICC 0.881; 0.932; 0.818 and 0.940, respectively, for the second evaluation. The mean intrarater reliability for the 4 SFGS scores was ICC=0.791; 0.906; 0.770 and 0.905. Discussion: There is now a valid German version of the SFGS available that can be used even by novices. The German version is suitable for evaluation of facial palsies in clinical routine and studies to allow a better comparability of German patients with results of the international literature.

Thirty-Day Perioperative Outcomes in Pediatric Parotidectomy.

IMPORTANCE: Limited information exists about the short-term morbidity of parotidectomy in children. This information is important when counseling parents and planning treatment for children with parotid masses. OBJECTIVE: To examine 30-day perioperative outcomes after parotidectomy in the pediatric population. DESIGN, SETTING, AND PARTICIPANTS: A prospective case series of 87 pediatric patients who underwent parotidectomy from January 1, 2008, to June 30, 2015, performed by 2 pediatric head and neck specialists in a tertiary care pediatric hospital. MAIN OUTCOMES AND MEASURES: Thirty-day perioperative complications, postoperative facial nerve function, reoperation rates, and readmission rates were the main outcome measures. Secondary outcome measures were operative time and length of stay. RESULTS: Ninety parotidectomies (71 superficial and 19 total) were performed in 87 patients (48 male and 39 female). Mean age at operation was 8.3 years. Eighty-five of the cases (94%) were performed for benign disease. Mean operative time was 4.09 hours (range, 1.58-10.43 hours) and mean length of stay was 2.24 days (range, 0.97-4.33 days). Immediate postoperative facial weakness was observed in 32 cases (36%); 10 of these cases (31%) involved the upper branch and 29 (90%) involved the lower branch. Immediate postoperative paresis occurred more often after total parotidectomy vs superficial parotidectomy (11 of 19 [58%] vs 21 of 71 [30%]; P = .03) but was unrelated to the etiologic cause of the patients' parotid disease. Thirty of 32 cases (94%) of facial nerve weakness were transient, and the mean time to resolution was 61 days. Eleven complications (12%) other than facial nerve weakness occurred during the 30-day postoperative period. Three patients (3%) required a return to the operating room for hematoma or wound dehiscence. One patient (1%) required readmission in the 30-day postoperative period for contralateral parotitis. CONCLUSIONS AND RELEVANCE: We observed a low rate of 30-day perioperative complications as a result of superficial or total parotidectomy for pediatric parotid disease. Major adverse events included return to the operating room and 1 wound infection. Only 1 patient required readmission. Transient weakness of the facial nerve is relatively common, observed more often in the lower division, and can be expected to resolve in most patients by an average of 2 months.

Weighting of Facial Grading Variables to Disfigurement in Facial Palsy.

IMPORTANCE: A universal, health care professional-graded scale for facial assessment would be a useful tool for reporting, comparing, and assessing facial function among patients with facial paralysis. OBJECTIVES: To correlate scores of an assessment tool, the eFACE scale, with expert-rated facial disfigurement and to determine the relative contributions of facial features to facial palsy-related disfigurement. DESIGN, SETTING, AND PARTICIPANTS: The eFACE scale yields 15 individual variable scores, in addition to subscores for static, dynamic, and synkinesis elements, and a total score that is based on 100-point scales. Two hundred patients with varying degrees of unilateral facial palsy underwent independent eFACE assessment and assignment of a disfigurement score by 2 facial nerve surgeons. The mean scores were determined, and multivariate regression analysis was performed to fit eFACE subset scores (static, dynamic, and synkinesis) to disfigurement ratings. A hybrid regression model was then used to weight each of the 15 eFACE variables, using stepwise regression to control for the effect of the other variables. Scoring was performed during an 8-week period from March 16 to May 8, 2015. MAIN OUTCOME AND MEASURE: Use of the 100-point eFACE variables, together with a 100-point visual analog scale of disfigurement, with 0 representing the most extreme disfigurement possible from a facial nerve disorder and 100 representing no discernible facial disfigurement. RESULTS: In the 200 patients included in analysis (126 [63.0% female]; mean [SD] age, 46.5 [16.4] years]), predicted disfigurement scores based on eFACE subset scores demonstrated excellent agreement with surgeon-graded disfigurement severity (r2 = 0.79). Variable weighting demonstrated that the 6 key contributors to overall disfigurement were (in order of importance) nasolabial fold depth at rest (normalized coefficient [NC], 0.18; P < .001), oral commissure position at rest (NC, 0.15; P < .001), lower lip asymmetry while pronouncing the long /e/ (NC, 0.09; P < .001), palpebral fissure width at rest (NC, 0.09; P < .001), nasolabial fold orientation with smiling (NC, 0.08; P = .001), and palpebral fissure width during attempts at full eye closure (NC, 0.06; P = .03). CONCLUSIONS AND RELEVANCE: A mathematical association between eFACE-measured facial features and overall expert-graded disfigurement in facial paralysis has been established. For those using the eFACE grading scale, predictions of the specific effects of various interventions on expert-rated disfigurement are now possible and may guide therapy. LEVEL OF EVIDENCE: NA.

Emerging vs Time-Tested Methods of Facial Grading Among Patients With Facial Paralysis.

IMPORTANCE: Most rehabilitation specialists and many facial reanimation surgeons use the Sunnybrook Facial Grading System (FGS) to measure and detect changes in facial function. The eFACE, an electronic and digitally graded facial measurement scale, was recently created to provide similar information to the Sunnybrook FGS, but with scaling uniformity across all categories of facial function, graphical outputs, and easy-to-use visual analog scales. OBJECTIVES: To establish the correlation between the scores on the eFACE and the Sunnybrook FGS among patients with facial paralysis and to compare the reliability of the 2 scales. DESIGN, SETTING, AND PARTICIPANTS: A retrospective review of medical records identified 109 patients who were evaluated at a facial nerve center by physical therapists using the eFACE and the Sunnybrook FGS on the same day, between November 1, 2014, and May 31, 2015. The level of facial function predicted using the 2 scales was compared to study correlation between the scales. Data analysis was conducted from June 1 to September 1, 2015. MAIN OUTCOMES AND MEASURES: Correlation between the Sunnybrook FGS and the eFACE grading scale. METHODS: Two independent physical therapists evaluated patients using both the eFACE and the Sunnybrook FGS. Scores were compared and the Spearman rank correlation coefficient was calculated between the total scores and each of the 3 subscores, including static, dynamic, and synkinesis scores. The total Sunnybrook FGS synkinesis score (worst score, 15; perfect score, 0) and static score (worst score, 20; perfect score, 0) were normalized to a 100-point scale with the eFACE (perfect score, 100; worst score, 1). RESULTS: eFACE scores ranged from 48 to 100, and Sunnybrook FGS scores ranged from 0 to 100. Among 109 patients, there was a moderately strong correlation between eFACE and Sunnybrook FGS scores in both total and subcategory scores. The Spearman rank correlation coefficient of the total eFACE and Sunnybrook FGS was 0.75 (r < 0.0001). For the static scores, the correlation coefficient was -0.71 (r < 0.0001). The correlation coefficients for the dynamic and synkinesis scores were 0.77 (r < 0.0001) and -0.78 (r < 0.0001), respectively. CONCLUSIONS AND RELEVANCE: There is moderately good agreement between the Sunnybrook FGS and the eFACE. Given the ease of using the eFACE on mobile devices, as well as its additional functionality, it may represent a reasonable facial grading option across disciplines in the future. LEVEL OF EVIDENCE: NA.

Idiopathic recurrent facial palsy: Facial nerve decompression via middle cranial fossa approach.

OBJECTIVE: To introduce our experience of preventing further episodes of idiopathic recurrent facial palsy by facial nerve decompression via middle cranial fossa approach. METHODS: Twelve cases (surgery group) who had idiopathic recurrent facial palsy underwent facial nerve decompression via middle cranial fossa approach, and 6 cases (control group) who declined surgery accepted conservative treatment. Further episodes of facial palsy and final outcomes of facial nerve were recorded. Facial nerve function was assessed by House-Brackmann facial nerve grade system. RESULTS: Only 8.3% of the patients (one case) in the surgery group had further episodes of facial palsy on the surgical side, but up to 64.7% of the patients (4 cases) in the control group suffered further episodes (p<0.05). 11 patients (91.7%) in the surgery group recovered to Grade I or Grade II in contrast to 3 cases (50%) in the control group. CONCLUSIONS: Facial nerve decompression via middle cranial fossa approach was able to prevent further episodes of idiopathic recurrent facial palsy, and surgical decompression seemed to achieve better outcomes of facial nerve than conservative treatment.

[Hypoglossofacial anastomosis for facial palsy treatment: Indications and results]. / Réhabilitation de la face paralysée par anastomose hypoglosso-faciale. Indications et résultats.

UNLABELLED: Hypoglossofacial anastomosis is a classical surgical procedure for the treatment of facial paralysis when the trunk of the facial nerve cannot be repaired and its peripheral branches are normal. PATIENTS AND METHODS: Between 2004 and 2015, 77 patients were able to benefit from an hypoglossofacial anastomosis. The etiology of the paralysis was mainly the surgery of vestibular schwannoma, tumors of the facial nerve and diseases of the brainstem. A specific and premature speech therapy remediation was realized for all patients in order to preserve the tongue function and to upgrade the facial motricity. RESULTS: Sixty-nine patients could be studied. The House Brackmann grading scale was used to appreciate the result. Thirty-one patients are grade III, 34 grade IV and in only one case the result is a grade V despite the anastomosis works. The main predictive factor for a good result is a small delay between the onset of the paralysis and the surgery for the rehabilitation. The specific physiotherapy upgrades the result with less side effects of the anastomosis. CONCLUSION: Hypoglossofacial anastomosis is a simple and reliable surgical procedure for rehabilitation of paralysed face. The quality of the result is linked with an early surgery and a specific physiotherapy.
