Backgrounds: Electrodiagnostic tests have been developed to estimate the degree of facial nerve injury during the acute phase. Side-to-side amplitude comparison with the affected side expressed as a percentage of the nonaffected side has been one of the most valuable electrophysiologic methods of assessing facial nerve functioning. This study was designed to know whether there is any difference in the side-to-side comparison of amplitudes and terminal latencies of the compound muscle action potentials (CMAP) of the facial muscles in the patients with Bell's palsy. Methods: Electroneurographic recordings with surface electrodes on the frontalis, orbicularis oculi, nasalis, and orbicularis oris muscles were made within 2 weeks post-onset (mean, day 7) in 39 patients. Results: Of the 39 Bell's palsy patients, 38 patients (97.4%) recovered satisfactorily within 6 months. The amplitude of CMAP in all patients was not reduced to 10% or less of that of the contralateral healthy muscle. The correlation of amplitude change between four facial muscles was relatively strong, but the correlation of latency change was weak. When the electroneurographic values were compared in the four muscle groups, the general linear models procedure did not show any significant difference for CMAP amplitude and latency changes (p=0.62-0.63). Conclusions: This study did not show any significant clinical advantage of electroneurographic recordings in more than one facial muscle at the early stage of Bell's palsy.

Background: The purpose of this study was to determine the effect of massage and muscle reeducation training with conventional treatment in patients with facial paralysis. Methods: Twenty-five patients with facial nerve paralysis were randomly allocated to 3 groups: massage, muscle reeducation training, and control groups. Therapeutic intervention for the massage (n=8) and muscle reeducation training (n=8) groups consisted of conventional therapy such as application of hot pack and electrical stimulation plus massage therapy and muscle reeducation training, respectively. The control group (n=9) received only conventional therapy. Therapeutic intervention for each group was performed 6 times per week for 4 weeks. The patients were assessed by using the House-Brackmann Grading System (H-B grade) and Yanagihara Unweighted Grading System (Y grade) once every week. Results: The H-B and Y grades improved significantly in all 3 groups after a 4-week intervention (p<.01). At 3 and 4 weeks, the H-B and Y grades of the massage group improved significantly when compared with those of the control group (p<.01). Muscle reeducation training group showed significant improvements in the scores of the two grades with time when compared with the massage and control groups (p<.01). The rate of change in the H-B grade was significantly different between the control and muscle reeducation training groups (p<.01), and that of change in the Y grade was significantly different between the control and muscle reeducation training groups (p<.01) and between the control and massage groups (p<.01). Conclusion: These findings suggest that massage and muscle reeducation training are more effective in improving the condition of patients with facial nerve paralysis than conventional therapy. In particular, the results of this study indicate that muscle reeducation training can be recommended by clinicians since it provides more benefits.

Patients who miss teeth partially or fully show many changes which make them lose function and esthetics.From the esthetic point of view, loosing teeth makes lower face unharmonized. There are various changes of lower and whole face according as how much change oral cavity is. Restoring the multiple teeth missing properly can make patient's face harmonized. Especially full mouth implant restorations can cause drastic occlusal change affecting masticatory muscles. Because all the muscles are connected closely, the masticatory muscles which is part of lower facial muscles can cause whole muscle change. In full mouth implant restoration case, I will show the whole face muscle change harmonized by meticulous occlusal treatment process. Full mouth restorations installed in right way show whole face muscle changes extending to head and neck muscles.

Objective : The face is very important for human communication. So facial palsy patients experience not only physical disturbances but also serious emotional stress. Therefore the focus of treatment must be to not only aid the recovery of objective symptoms but also the improvement of subjective quality of life. However there has not been enough Oriental Medical study in this field until now. Thus this study was begun to suggest a useful index for the treatment of facial palsy. Methods : Grade of paralysis, sequelas, and quality of life were used for evaluation. To evaluate Grade of paralysis, House-Brackman Grade was used as the Gross scale and Kim's Grade was used as the Regional scale. Sequelas were evaluated by muscle contraction, synkinesis, NA, and grade of philtrum tilt. Quality of life was evaluated by SF-36v2, Facial Disability Index, and Vas. Results & Conclusion : 1. The change of grade of paralysis between the early and the present time reveals remarkable improvement statistically. 2. There was a remarkable improvement in all parts of quality of life except several areas of SF-36(RP, RE, MH, VT) 3. In only PF(Physical Function) of FDI, quality of life increased remarkably according to the improvement of grade of paralysis. 4. There is the positive relationship among Kim's grade, HB grade and Synkinesis 2. 5. Synkinesis among sequelas has the greatest effect on quality of life. And muscle contraction, change of NA, and grade of philtrum tilt also affect quality to some extent. 6. There was no remarkable relationship between the period of illness and change of quality of life. 7. Change of NA is shown after 3 months of illness and synkinesis becomes worse after 6 months of illness.

The function of the masseter and anterior temporal muscles was assessed by electromyography in 30 patients with mandibular prognathism (20 patients with facial asymmetry and 10 patients without facial asymmetry) before orthognathic surgery and 4weeks afterwards. Electromyogram(EMG) recordings were made during resting, clenching and swallowing. We compared with right-left difference of this recording and asymmetry index before and after orthognathic surgery. The result of this study was as follows. 1. There was no significant right-left difference in muscle activities of masticatory muscles both asymmetric groups and controls and many variable change after orthognathic surgery.(P>0.05) 2. The mean electric activity of the masticatory muscles was found to have decreased during more clenching than resting, but there was no statistically significant difference because of individual difference of measuring values.(P>0.05) 3. The asymmetry index of masticatory muscles in asymmetric groups was significantly greater during clenching compared with controls.(P<0.05) In conclusion, no right-left difference of muscle activities was found in patients with facial asymmetry before orthognathic surgery and 4weeks afterwards. Not only muscular functioning but also many other factors, such as occlusion, temporomandibular joint disorder and trauma, probably affect facial asymmetry and will be analyzed in future studies. And we will need long term follow-up after orthognathic surgery.

In this study, we apply the facial Facial Action Coding System for coding the muscular system anatomical approach facial expressions to be displayed in response to a change in sensitivity. To verify by applying the virtual character the Duchenne smile to the original. I extracted the Duchenne smile by inducing experiment of emotion (man 2, woman 2) and the movie theater department students trained for the experiment. Based on the expression that has been extracted, I collect the data of the facial muscles. Calculates the frequency of expression of the face and other parts of the body muscles around the mouth and lips, to be applied to the virtual character of the data. Orbicularis muscle to contract end of lips due to shrinkage of the Zygomatic Major is a upward movement, cheek goes up, the movement of the muscles, facial expressions appear the outer eyelid under the eye goes up with a look of smile. Muscle movement of large muscle and surrounding Zygomatic Major is observed together (AU9) muscles around the nose and (AU25, AU26, AU27) muscles around the mouth associated with openness. Duchen smile occurred in the form of Orbicularis Oculi and Zygomatic Major moves at the same time. Based on this, by separating the orbicularis muscle that is displayed in the form of laughter and sympathy to emotional feelings and viable large muscle by the will of the person, by applying to the character of the virtual, and expression of human I try to examine expression of the virtual character's ability to distinguish.

Facial asymmetry is found in patients with or without cosmetic facial alterations. Some patients have facial asymmetry that manifests underlying skeletal problems, while others have only limited soft-tissue facial asymmetry. Orthognathic surgery brings about a dermatic change, as soft tissue covers underlying bones. Limited soft-tissue asymmetry, meanwhile, is difficult to correct. The treatment modalities for the creation or restoration of an esthetically pleasing appearance were autogenous fat grafts, cartilage graft, and silicon injections. A young female patient had right-side facial asymmetry. The clinical assessment involved visual inspection of the face and palpation to differentiate soft tissue and bone. Although the extra-oral examination found facial asymmetry with skin atrophy, the radiographic findings revealed no mandibular atrophy or deviation. She was diagnosed as localized scleroderma with muscle spasm. In conclusion, facial asymmetry patients with skeletal asymmetry can be esthetically satisfied by orthognathic surgery; however, facial atrophy patients with skin or subdermal tissue contraction need treatment by cosmetic dermatological surgery and orthodontic correction.

Since G.N. Hounsfield's clinical use of computed tomography in 1971, digital imaging technique using computers has shown an eye opening progress. Progress has made 3-dimensional understanding of not only facial bones but muscles and other connective tissues possible through 3-dimensional reconstruction of preexisting tomographical images. Also, quantitative analysis of density, distance, volume has become possible, allowing objective analysis of preoperative and postoperative states through imaging. The authors measured the masseter muscle volume of 20 normal individuals and 8 female patients through 3-D reconstructive CT imaging and made a statistical analysis of the measurements. The method used in our study may be applied to the diagnosis of disease causing the change of the facial volume and presurgical design as a useful tool to provide objective information on the evaluation of surgery outcome.
