Purpose: The purpose of study was to determine the effects of muscle reeducation training in patients with acute facial nerve paralysis. Methods: Thirty patients were randomly assigned to either the experimental group (n=15) or the control group (n=15). The experimental group received muscle reeducation training for 20 minutes after electrotherapy and the control group received conventional electrotherapy for only 40 minutes. Therapeutic intervention for each group was performed four times per week for four weeks. The patients were measured for recovery of paralysis using the House-Brackmann Grading System (H-B grade), the Movement Distance of Mouth, Nasolabial Angle (NA), and Facial Disability Index (FDI). Results: In within group comparison, the experimental group showed significant improvements for all variables (p<0.01). In comparison between two groups, the experimental group showed relatively greater significant improvements for all variables (p<0.01). Conclusion: These findings suggest that muscle reeducation training is more effective than conventional therapy in improving the condition of patients with facial nerve paralysis. In particular, the results of this study indicate that muscle reeducation training can be recommended by clinicians since it provides more benefits.

Objectives : Facial nerve palsy is a rare but well-known complication that occurs after a tooth extraction. The paralysis follows the injection of a local anesthetic, but patients typically recover after a few hours. However, there are a number of reports of delayed paralysis, and the cause of delayed facial palsy remains uncertain. This study is the first case report detailing how Korean medicine can be used to treat facial nerve palsy following tooth extraction. This study reports our experience of a patient's favorable recovery. Methods : A 25-year-old male patient experienced acute facial palsy after four premolar teeth were extracted. He was hospitalized in the Pusan National University Korean Medical Hospital. We provided complex Korean traditional medical treatments such as acupuncture, cupping, use of a hot water steamer, and herbal medicine for 18 days. Results : Using the Yanagihara Grading Score, we found improvements in the patient's voluntary facial movement as his score increased from 22 to 34. Furthermore, his accompanying symptoms, such as dry eye and facial pain, disappeared. However, the patient reported transient pain around acupoints after the acupuncture intervention. Conclusion : Our study suggests that Korean medical treatments might be effectively used to treat facial nerve palsy after tooth extraction, although further research should be conducted due to the limited number of cases in this area.

Objectives : This study was to compare the incipient grade and improvement rate between each opposite gender and part on peripheral facial nerve paralysis. Methods : We investigated 64 cases of patient with peripheral facial nerve paralysis and divided into four groups with each gender and affected part and compared their incipient grade and rate of improvement. All groups were evaluated by Yanagihara's unweighted grading system before treatment and in everyday and after treatment. Results & Conclusion : 1. There's a difference of incipient grade between each opposite affected lesion in male. But there was not significant statistics. 2. There's no difference of incipient grade between each opposite affected lesion in female. 3. There's a difference of incipient grade between each opposite gender, affected their right side. But there was not significant statistics. Left side affecting palsy is more severe than right in male, and reversed results in female. But there were not significant statistics. There's no differences between each affected lesion in female. 4. There's no differences of improvement rate between each affected lesion in female. 5. The group, affected right side had better rate of improvement than another in male. But it's not significant statistics. 6. Male group had better rate of improvement than female in both gender, affected its left lesion. But it's not significant statistics.

Background and Objectives: The aim of the present study was to assess the feasibility of a PC-based facial asymmetry assessment program (PC-FAAP) and to compare the results of PC-FAAP with subjective regional scoring by raters in acute unilateral peripheral facial nerve paralysis (FNP). Subjects and Methods: Participants were divided into 3 groups with 8 participants per group: group I, normal; group II, mild to moderate FNP; and group III, severe FNP. Using the PC-FAAP, the mouth asymmetry ratio (MAR), eyebrow asymmetry ratio (EAR), and complete eye closure asymmetry ratio (CAR) were calculated by comparing the movement of tracking points on both sides. The FNP grading scale (FGS) integrated each score, and the scores were weighted with a ratio of 5:3:2 (MAR:CAR:EAR). Subjective regional scoring was measured on a 0-100 scale score by three otologists. PC-FAAP and subjective scoring were compared in each group regarding the consistency of the results. Results: The mean scores of the MAR, EAR, CAR, and FGS of each group were significantly different. PC-FAAP showed significant differences between the three groups in terms of MAR, EAC, CAR, and FGS. PC-FAAP showed more consistent results than subjective assessment (p<0.001). The PC-FAAP was significantly more consistent in group I and group III (p<0.001 and p=0.002, respectively). FGS in group III was the only parameter that showed a more consistent result in PC-FAAP than the subjective scoring (p=0.008). Conclusions: An FNP grading system using a PC-based program may provide more consistent results, especially for severe forms.

Objectives The purpose of this study is to analyze the latest clinical trends in peripheral facial nerve palsy pediatric and adolescent patients who treated in Korean medicine hospital. Methods The study was conducted based on 185 cases of pediatric and adolescent patients with peripheral facial nerve paralysis who visited Korean medicine hospital from January 2017 to June 2022. Results The mean age of onset of facial nerve paralysis in children and adolescents was 11.7 years, and the incidence rate was higher in boys than in girls. The seasonal distribution was the most common in autumn, and 91.4% were diagnosed with Bell's palsy. The recurrence rate was 7.6%. The severity was evaluated on the House-Brackmann Grading System (HBGS) scale, and the most common was Grade III. It took an average of 6.5 days from the date of onset to visit the hospital, and 75.7% visited the hospital within a week from the date of onset. Hospitalized treatment was 69.2%. The higher the HBGS grade, the more hospitalized treatment was, and the total number of treatments and the duration of treatment tended to increase. The average treatment period from the first visit date was 119.6 days. 17.8% received only Korean medicine treatment, and 69.2% took Western medicine with herbal medicine. Conclusions In this study, there was a difference in the average treatment period from previous studies according to the study period setting. Long-term studies on the recovery rate and prognosis of pediatric facial paralysis are needed.

Herpes zoster oticus which is called Ramsay Hunt syndrome, geniculate ganglion herpes and otic herpes, is characterized by a viral prodrome with otalgia, vesicular eruptions, facial paralysis, hearing disturbance, tinnitus, vertigo and other symtoms. Among cranial nerves, trigeminal and facial nerves are the most commonly affected in patients with herpes zoster oticus, but on rare occasions 8th, 9th, 10th, 11th, 12th cranial nerves and even the upper cervical nerve are influenced as well.. In general, it has poor prognosis compared with Bell's palsy, leaving permanent facial nerve dysfunction. We report a case of Herpes zoster oticus, which was fully recovered by acupuncture and herbal medication within 12 days. We used $FEMA^{11)}$ and House-Brackmann's grading system to assess the degree of paralysis in each part of face.

Background: This retrospective study aimed to determine whether there were correlations between the number and type of accompanying symptoms of peripheral facial nerve palsy, and surface electromyography (SEMG) and clinical assessment scales to help diagnosis. Methods: There were 30, cases of peripheral facial nerve palsy at Visit 1 to the Korean Medicine Hospital, Dong-eui University, 22 cases at Visit 2 and 10 cases at Visit 3. The study period was from July 19, 2021 to November 31, 2021. Symptoms were evaluated three times (with two-week intervals which began 7 days from onset) using SEMG, clinical assessment scales and accompanying symptoms. In this study, the House-Brackmann grading system (HBGS), and the Yanagihara's unweighted grading system (Y-score) clinical assessment scales were used. The Pearson or Spearman correlation was used for statistical analysis. Results: On Visit 1, the number of accompanying symptoms of peripheral facial nerve palsy had no significant correlation with other measures. On Visits 1-3, the HBGS score had a significant negative correlation with the Y-score. On Visit 2, most of the mean values measured had significant correlations with each other although not between SEMG-Z and SEMG-O that Z means a zygomaticus muscle and O means a orbicularis oris muscle. On Visit 3, the number of accompanying symptoms significantly correlated with the clinical assessment scales. The HBGS score, Y-score, and SEMG measurements (except SEMG-Z) had significant correlations with each other. A significant positive correlation between SEMG-Z and SEMG-T was noted. Conclusion: We predict accompanying symptoms can be used to diagnose the peripheral facial nerve palsy including both clinical assessment scales and SEMG measurements at 2-5 weeks after onset.

Background and purpose: Bell‘s Palsy is a condition that causes the facial muscles to weaken or become paralyzed. It's caused by trauma to the 7th cranial nerve, and is not permanent. The aim of this study is to be convinced of differences between facial electrodermal activities of paralyzed side and those of normal side in acute stage of Bell's Palsy patients Methods: Electrodermal activity (EDA) was performed within 1 week after the onset of facial palsy and facial nerve electromyography (EMG) at 2 weeks after the onset. The recovery of facial nerve function was documented by House and Brackmann grading. All the patients were followed up weekly until recovery or up to 6 weeks. Results: There was significant differences (conductivity A: t=3.319, p=0.002; conductivity C: t=2.699, p=0.010) between facial electrodermal conductivities of paralyzed side and those of normal side in acute stage of Bell's Palsy patients (N=45). And the result showed that logarithmic scale of electrodermal conductivity A value ratio obviousely decreased with logarithmic scale of EMG zygomatic branch amplitude ratio (r=-0.472, p=0.143); logarithmic scale of capacitance B, logarithmic scale of EMG temporal branch amplitude ratio (r=-0.422, p=0.133); logarithmic scale of conductivity C, logarithmic scale of EMG buccal branch amplitude ratio (r=-0.545, p=0.083) (N=12). Conclusion: Electrodermal conductivities increased in paralyzed facial side in acute stage of Bell's Palsy patients.

Bell's palsy is an acute facial paralysis caused by peripheral facial nerve dysfunction. The aim of this study is to assess the efficacy of Korean medicine in the treatment of three patients who were hospitalized and diagnosed with Bell's palsy within 2 weeks of coronavirus disease 2019 (COVID-19) infection. The patients were administered with Korean medicine treatments, steroids, and antiviral drugs. Moreover, the Korean medicine treatments include acupuncture, pharmacopuncture, moxibustion, physical therapy, and herbal medicine. Symptom improvement was evaluated daily using the Yanagihara facial nerve grading system, a facial function evaluation tool. Furthermore, it was suggested that the patients affected by Bell's palsy after COVID-19 infection may have a slower improvement in their treatment progress compared with those without COVID-19 infection in the acute stage.
