Objectives : Among the assessment tools for evaluating facial function, the House-Brackmann scale is used as a standard tool, but it has some shortcomings. The Sunnybrook Facial Grading System can assess the after effects of facial palsy and facial movement by each part of the face. By understanding the application state of this Sunnybrook Facial Grading System, we intend to analyze the relationship between House-Brackmann scale score and Sunnybrook Facial Grading System score so that we can examine the advantages of the Sunnybrook Facial Grading System as a more accurate tool. Methods : We screened both inpatients and outpatients who visited the Facial Palsy Center at Kyung Hee University Hospital for Korean medical treatment and were evaluated with the Sunnybrook Facial Grading System from December 2015 to October 2016. A total of 159 out of 166 patients were studied, including basic characteristics and missing data. We used descriptive statistics for general features of patients and SPSS Ver.18 for statistical analysis. Results : House-Brackmann scale and Sunnybrook Facial Grading System have high negative correlation through Pearson Correlation Coefficient with a score of -0.884. Analyzing outlier data resulting from relation analysis between the House-Brackmann scale and the Sunnybrook Facial Grading System showed many outliers when the damaged state of each part of the face is different. Conclusion : Sunnybrook Facial Grading System can make up for faults of the House-Brackmann scale, which is inferior in accuracy when each damage status of each part of the face is different. Sunnybrook Facial Grading System performs a detailed assessment of facial function and sequelae of facial palsy easier than the House-Brackmann scale.

The goal in facial paralysis treatment is to achieve the normal appearance of the face as well as to reconstruct the natural symmetrical smile. In cases of facial paralysis, a widely accepted procedure is the two stage method, which combines neurovascular free muscle transfer with cross face nerve grafting. Although the results are promising, the two operations of this method, which are about 1 year apart, impose an economic burden on the patients and require a lengthy period before results are obtained. In order to overcome these drawbacks, one stage method, using latissimus dorsi neurovascuular free muscle flap was introduced. Between January 2000 and January 2004, fifteen patients with long standing facial paralysis were treated in the Korea University Anam Hospital. The segmental latissimus dorsi with long nerve and pedicle was transferred to the paralyzed side of the face. The first postoperative movement of the transferred muscle was reported at 8.9 months, faster than that of the two stage method. During the next 24 months, a constant increase in the power of muscle contraction was observed. The fifteen cases were evaluated within an average of 31.7 months following the surgery and satisfactory results including muscle contraction were obtained in eleven of the cases but muscle contraction was not found in three cases.

Objectives : The purpose of this study was to report a case of a patient efficacy of electromagnetic acupuncture using Whata 153 in facial nerve palsy in Herpes zoster oticus. Methods : We treated the patient with magnetic acupuncture combined with electro-acupuncture. Acupuncture points were at the face (BL2, GB14, TE23, ST4, ST6, ST3). All the acupuncture points were stimulated with magnetic field and 4 of them were combined with electro-acupuncture. Results & Conclusions : The improvement of facial movement and symptom was evaluated by Yanagihara grading system(Y-system), House-Brackmann scale(HB scale) and Sunnybrook facial grading system(SFGS). After treatment, all of the scales(Y-system, HB scale and SFGS) and symptom of the patient were improved. From the above results, we suggest that magnetic acupuncture and electro-acupuncture might be effective on facial nerve palsy in Herpes zoster oticus.

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 : The purpose of this study is to investigate the mechanism of Cosmetic Acupuncture through reinterpretation of anatomy and physiology. Methods : The causes of wrinkle increases and rapid aging of facial skin were studied and the theoretical system of Cosmetic Acupuncture treatment was analyzed through anatomy and physiology reinterpretation. Results and Conclusions : An increase in wrinkles and rapid aging of facial skin is caused by xerosis. Skin condition represents the condition of subcutaneous muscle. The reason why skin becomes easily dry is the heat produced by craniofacial part. Craniofacial part always generates lot of physiological fever because of the muscles. This physiological fever is produced from the muscles that are responsible for maintaining skull suture, controlling the movement of temporomandibular joint, maintaining head and neck posture. Controlling this fever is the crux of Cosmetic Acupuncture mechanism. These muscles correspond to Foot Taeyang meridian-muscle, Foot Soyang meridian-muscle and Foot Yangmyung meridian-muscle. Cosmetic Acupuncture is effective for preventing facial skin from aging and wrinkle increase by mechanical stimulus on facial muscles, and for controlling craniofacial part meridian-muscle system producing the heat.

Facial nerve schwannomas (FNSs) are usually painless, slow-growing, and without specific symptoms, so that early diagnosis may be difficult. They are particularly liable to being misdiagnosed as parotid gland origin benign tumor before surgery, which can lead to unnecessary parotidectomy or unexpected facial nerve injury. To prevent these complications, it is important that the correct diagnosis is performed at least in intraoperative time. When an adhesion between the mass and the facial nerve is exist or when electrical stimulation of the mass triggers facial movement, FNS is highly suggested diagnosis. In such cases, frozen section analysis should always be performed. In this case, the pre-operative diagnosis from clinical examination and MRI was pleomorphic adenoma. However, intraoperative features led us to suspect that the mass originated from facial nerves, and intraoperative frozen section analysis yielded results consistent with a schwannoma. Based on this intraoperative diagnosis, we carried out a successful conservative treatment with preservation of facial nerve.

Background Temporalis muscle transfer produces prompt surgical results with a one-stage operation in facial palsy patients. The orthodromic method is surgically simple, and the vector of muscle action is similar to the temporalis muscle action direction. This article describes transferring temporalis muscle insertion to reconstruct incomplete facial nerve palsy patients. Methods Between August 2009 and November 2011, 6 unilateral incomplete facial nerve palsy patients underwent surgery for orthodromic temporalis muscle transfer. A preauricular incision was performed to expose the mandibular coronoid process. Using a saw, the coronoid process was transected. Three strips of the fascia lata were anchored to the muscle of the nasolabial fold through subcutaneous tunneling. The tension of the strips was adjusted by observing the shape of the nasolabial fold. When optimal tension was achieved, the temporalis muscle was sutured to the strips. The surgical results were assessed by comparing pre- and postoperative photographs. Three independent observers evaluated the photographs. Results The symmetry of the mouth corner was improved in the resting state, and movement of the oral commissure was enhanced in facial animation after surgery. Conclusions The orthodromic transfer of temporalis muscle technique can produce prompt results by applying the natural temporalis muscle vector. This technique preserves residual facial nerve function in incomplete facial nerve palsy patients and produces satisfying cosmetic outcomes without malar muscle bulging, which often occurs in the turn-over technique.
