Facial palsy is commonly encountered disease in the clinic but bilateral facial palsy is known as rare disease. Type of facial nerve paralysis include unilateral, recurrent ipsilateral, recurrent alternating and bilateral simultaneous palsies. Among the types, the reported incidence of bilateral simultaneous palsy is 0.3~2% of facial paralysis patients. We experienced I case of patient with bilateral simultaneous facial palsy that was concluded as bilateral bell's palsy. Objective : The purpose of this paper is to report the patient with bilateral facial palsy, who improved by oriental medical treatment. Another purpose is to review the current literature and to differential diagnosis of bilateral facial paralysis. Methods and Results : The patient was treated by acupuncture, herb medication and self-massage on facial muscle for 14 weeks. House-brackmann grading score was improved into I/I (Rt/Lt) from IV/IV. Conclusion : Through reviewing some literatures and reports, It is concluded that bilateral facial palsy was related to many other disorders and more ominous than unilateral facial palsy. therefore, its work-up should include a complete neurologic assesment and thorough evaluation. also, we consider that bilateral Bell's palsy can improve by oriental medical treatments.

The most important concern to do parotidectomy is correct identification of the facial nerve and preservation of the nerve function. Many descriptions for the localization and branching types of the facial nerve trunk have existed. During the parotid surgery, it is necessary to have knowledges about the incidence and prognostic aspect of a invasion of the facial nerve by the parotid tumors. The method of the dissection and the surgical extent of the parotid gland would be decided not only by the anatomic variation of the facial nerve. but also the size and location of the tumor. Invasion of the facial nerve in parotid malignancies is the most significant factors affecting the prognosis, so radical parotidectomy which consists of the total extirpation of the parotid gland in conjunction with resection of the facial nerve is often required for proper management. Radical parotidectomy is advocated for the surgical treatment of high grade malignancies and in selective recurrent benign tumors intimately involving the facial nerve. Unfortunately, the morphologic and functional deficits created by sacrificing the facial nerve can be emotionally and physically traumatizing to the patient. Therefore, when the facial nerve is sacrificed, immediate reconstruction of the facial nerve should be necessary. Immediate nerve repair with direct anastomosis of the resected nerve ends or placement of a cable nerve graft provides the better cosmetic and functional results. Surgical resection remains the mainstay of treatment for cancer of the parotid gland, and there is general agreement that facial nerve should not be sacrificed unless the tumor is adherent to, or surrounds the nerve. The following statement is described general principles of troublesome management of the facial nerve during surgery for parotid tumor.

Objective : The facial nerve trace on the ipsilateral side of the vestibular schwannoma was reconstructed by diffusion tensor imaging tractography to identify the adjacent relationship between the facial nerve and the tumor, and to improve the level of intraoperative facial nerve protection. Methods : The clinical data of 30 cases of unilateral vestibular schwannoma who underwent tumor resection via retrosigmoid approach were collected between January 2019 and December 2020. All cases underwent magnetic resonance imaging examination before operation. Diffusion tensor imaging and anatomical images were used to reconstruct the facial nerve track of the affected side, so as to predict the course of the nerve and its adjacent relationship with the tumor, to compare the actual trace of the facial nerve during operation, verify the degree of coincidence, and evaluate the nerve function (House-Brackmann grade) after surgery. Results : The facial nerve of 27 out of 30 cases could be displayed by diffusion tensor imaging tractography, and the tracking rate was 90% (27/30). The intraoperative locations of facial nerve shown in 25 cases were consistent with the preoperative reconstruction results. The coincidence rate was 92.6% (25/27). The facial nerves were located on the anterior middle part of the tumor in 14 cases, anterior upper part in eight cases, anterior lower part in seven cases, and superior polar in one case. Intraoperative facial nerve anatomy was preserved in 30 cases. Among the 30 patients, total resection was performed in 28 cases and subtotal resection in two cases. The facial nerve function was evaluated 2 weeks after operation, and the results showed grade I in 12 cases, grade II in 16 cases and grade III in two cases. Conclusion : Preoperative diffusion tensor imaging tractography can clearly show the trajectory and adjacent position of the facial nerve on the side of vestibular schwannoma, which is beneficial to accurately identify and effectively protect the facial nerve during the operation, and is worthy of clinical application and promotion.

Objectives : The purpose of this study is research on facial palsy sequelae and evaluating scale that have studied insufficiently until now. Methods : We researched on the symptoms, epidemiology and evaluating scale of facial palsy sequelae. For this, we searched the research papers on facial palsy sequelae and the clinical papers that find out the effect of treatment by evaluating facial palsy sequelae. Results : The symptoms of facial palsy sequelae are synkinesis, contracture, spasm, crocodile tears syndrome, tearing decrease, gustation impairment, hearing impairment, tinnitus, hyperacusis, etc. Among these, synkinesis, contracture, spasm and crocodile tears syndrome are the most frequently observed broadly. The poor prognosis factor of facial palsy can be the risk factor of facial palsy sequelae. For example, severe degeneration of facial nerve can be the risk factor of facial palsy sequelae. Most of clinical papers on facial palsy sequelae have used NRS(numeric rating scale) as evaluating scale. But NRS is very subjective scale. The scales of Stennert, Peitersen, Murata et al. can evaluate facial palsy sequelae grossly. Sunnybrook scale, Sydney scale, SAQ(synkinesis assessment questionnaire), the scale of Kim, the scale of Scott, HFS-7(hemi facial spasm), HFS-36 and Schirmer's test can evaluate the respective symptoms of facial palsy sequelae. Conclusions : The symptoms of facial palsy sequelae are synkinesis, contracture, spasm, crocodile tears syndrome, etc. Most of clinical papers on facial palsy sequelae have used NRS as evaluating scale. There were some scales that can evaluate facial palsy sequelae grossly and respectively. In future, we will need more progressed study of facial palsy sequelae and evaluating scale.

Purpose: The golden ratio has been used for a long time to objectify and quantify 'beauty'. Dr. Marqurardt claims that the golden ratio can be applied in the maxillofacial field as well. The purpose of this study was to evaluate the diagnostic significance of using a facial 'phi' mask for analyzing Korean faces with characteristics of Class I, II, and III malocclusion. Methods: We studied twenty five Korean celebrities' frontal facial photos (10 males, 15 females) and 90 malocclusion patients' frontal facial photos (30 patients in each malocclusion classification: Class I, Class II, and Class III). Patients who received orthodontic treatment at Samsung Medical Center were selected for this study. After superimposition of the selected facial photo and facial 'phi' mask using Adobe Photoshop CS3, the ratio of the entire facial area, mid facial area, lower facial area and horizontal and vertical lengths were measured. Results: The facial ratio in photos of Korean faces showed larger vertical and horizontal ratios than the facial 'phi' mask with golden ratio, regardless of skeletal malocclusion (entire face: 115%, lower face: 125% larger than the mask). The results of the frontal photos of Class I, II, and III malocclusion patients using facial 'phi' mask showed that the vertical length and frontal face area was more significantly influenced by the area of the lower face than the midface. This means that the lower face has larger proportions in the facial areas. Conclusion: The ratio of facial 'phi' mask is matched with the ideal facial appearance that the contemporary Korean general public is seeking. Thus, the facial 'phi' mask may be a convenient tool for esthetic analysis of Korean faces. Reducing the area of the lower face is esthetically more desirable for almost all Korean people when planning orthognathic surgery.

Objectives : Bell's palsy is the most common acute facial paralysis but its causes still unclear. At present, one of the most widely accepted cause is viral infections, and generally socioeconomic factors influence the viral infections. The purpose of this study is to investigate the relationship of incidence of facial palsy with socioeconomic factors. Methods : Seventeen patients with a acute facial palsy, who volunteered and completed all of the assessment measures participated. Using data on 17 participants, we examined the independent contribution of education, income, and occupation to a risk factor of severe facial palsy. Severity of global facial impairment was assessed by the facial disability index (FDI), the house-brackmann facial nerve grading system, WHO quality of life - bref (WHOQOL-BREF) and visual analogue scale (VAS) about discomfort of life. Results : There was no correlation between severity of facial palsy and gender, marriage, education, or occupation. Age greater than 60 years (p<0.05), and low monthly income(p<0.05), poor self-rated health was associated with greater severity of idiopathic facial paralysis. Conclusions : The number of subjects with facial palsy in our study (n-17) was small, and therefore generalization to larger patient populations might be unwarranted. But according to the outcome, we suggest that socioeconomic factors, especially low monthly income influence severity of bell's palsy.

Objectives : We investigate the characteristics of foot reflex zone acupoint of facial paralysis patients. Methods : In order to make a comparison between facial nerve paralysis patient group and non-facial paralysis group, we measured foot reflex zone acupoint detection in both group of 18 patients who were diagnosticated to facial nerve paralysis and 18 persons who were not. Results : 1. In comparing the means of the foot reflex zone, the measurements of facial nerve paralysis group is different significantly from non-facial paralysis group(p<0.05). 2. The measurement of detection of foot reflex zone acupoints, such as hypophysis(垂體), nose(鼻), cerebrum(大腦), neck(頸項), Trapezius muscle(僧帽筋), eye(眼) and ear(耳) of the facial nerve paralysis group is different significantly in comparison with non-facial paralysis group(p<0.05). But the measurement of detection of foot reflex zone acupoints, such as trigeminal nerve(三叉神經), cerebellum (小腦), kidney(腎), ureter(輸尿管) and urinary bladder(膀胱) of the facial nerve paralysis group is not defferent significantly in comparison with non-facial paralysis group(p>0.05). Conclusions : The results suggest that foot reflex zone can be used in the diagnosis and treatment of facial nerve paralysis.

We performed a retrospective study to evaluate the effect of posterior approach to facial nerve in parotid surgery, being the standard procedure in our hospital, on postoperative facial palsy and to access the safety of this procedure in preserving the function of facial nerve. A series of 176 parotid surgeries from 172 patients from January 1989 to December 1994 was analyzed, of which, 2 Schwannomas, 4 Kimura's diseases, 6 preoperative facial palsies, and 4 intentional nerve resections for malignancy were excluded. Factors such as pathology of tumor, extent of surgery, location of tumor, size of tumor, frequency of surgery were reviewed to determine if any factor contributed to the developement of facial palsy postoperatively. Of 160 parotidectomies, postoperative facial palsy was found in 58(36.3%), being temporary in 35(35. 6%), recovered within 12 months after surgery and permanent in 1(0.6%). Facial palsy occured in 47(35.7%) of 128 benign tumors, 42(89.5%) recovered completely within 6 months and in 11(34.4%) of 32 malignant tumors, 6(54.5%) within 6 months. Among the factors analyzed, postoperative facial palsy was found to be common in the tumors of deep lobe(p<0.02) and in total or neartotal parotidectomies(p<0.08). In our study, the factors of the location of tumor and extent of surgery would be contributable to developement of postoperative facial palsy and the surgical technique using posterior approach to the facial nerve may be a simple and safe surgical procedure for identification and preservation of facial nerve in parotid surgery.
