  • This study was examined for effects of acupuncture of Chok-Samni(ST36) on the facial thermography in health subjects, The volunteers who participating in this study had taken rest for 15 mins in room temperature (19-21 ℃) before the examination and informed them what to prohibit smoking, drinking and administration of drug for the previous day, The thermography of face was taken using Digital Infrared Thermographic Imaging (D.I.T.I. : Dorex, DTI-16UT1, U.S.A.) by time interval of 35 minutes at 15 min before and 20 min after acupuncture stimulation. Thermal temperature of Yangbaek(GB14), Myon-koryo(ST3) and Chichang(ST4) was measured and compared, The results showed that acupuncture of Chok-Samni(ST36) decreased the Absolute difference of temperature between Myon-koryo(ST3) and Chichang(ST4) (p<0,05, Data were represented mean±S,E.M.(n=33)), But, acupuncture of Chok-Samni(ST36) particularly decreased the absolute difference of temperature between Yangbaek(GB14) and Chichang(ST4) and particularly decreased the absolute difference of temperature between Vangbaek(GB14) and Myon-koryo(ST3) (p<0,05, Data were represented mean±S,E.M.(n=33)). Also, it was observed that acupuncture of Chok-Samni(ST36) decreased variety of the color tone of thermographic contour line and decreased thermal distribution. The results showed that acupuncture of Chok-5amni(ST36) significantly decreased the absolute difference of temperature of partial facial surface. Hereafter, study about if acupuncture of Chok-Samni(ST36) significantly decrease the absolute difference of temperature of all the areas of facial surface is requested. Also, continued study of effects of acupuncture of other meridian on the facial thermography is requested.

  • Objectives : The aim of this study was to investigate the characteristics of Ryodoraku and association of Ryodoraku in Idiopathic Facial Paralysis Patients Methods : Subjects were 53 patients with Facial palsy patients and 28 normal people. We calculated the average Ryodoraku score(RS, ${\mu}A$) and each variation from physiologic range of 12 Ryodoraku points, and investigated the incidence when left and right points were simultaneously below(bilateral deficiency) or above(bilateral excess) physiologic range. Results : The electric current value of several meridian of normal group was more higher in idiopathic facial palsy group than in normal group. The measurement value of Ryodoraku followed sex was not significant statistically. Conclusions : These findings suggest that the measurement value of several Meridians of Ryodoraku is more higher in idiopathic facial palsy group than in normal group, because Ryodoraku has low correlation with Parasympathetic nerve.

  • The treatment of mandibular subcondylar fractures is a matter of controversy. The majority of mandibular subcondylar fracture are treated by closed reduction, but the displaced or dislocated mandibular subcondylar fractures may be treated by open reduction. The characteristics of open reduction are the anatomical reduction, the functional restoration, the rapid function, the maintenance of vertical ramus dimension, the better appearance and the less resultant TMJ problem etc. When an open reduction is considered, the wire, miniplate, lag screw and Kirschner wire are available with internal fixation. Of these, Kirschner wire is a simple method relatively and correct positioning of the wire achieves rigid fixation. But many open reduction methods for mandibular subcondylar fractures require extraoral approach. The extraoral approach has some problems, the facial scar and the risk of facial nerve injury. On the other hand, the intraoral approach eliminates the potency of the facial scar and the facial nerve injury, but is difficult to access the operation site. Since the intraoral approach was first described by Silverman (1925), the intraoral approach to the mandibular condyle has been developed with modifications. The purpose of this article is to describe the intraoral technique with the Kirschner wire on mandibular subcondylar fractures. Conclusion : The intraoral reduction with Kirschner wire on mandubular subcondylar fractures avoids the facial scar and facial nerve injury and is simple method to the extraoral approach. And it has minimal morbidity and better esthetics.

  • This study was examined for effects of acupuncture of Zusanli (ST36) on the facial thermography in health subjects. The volunteers who participating in this study had taken rest for 20 - 30 mins in room temperature (23-$25^{\circ}C$) before the examination and informed them what to prohibit smoking, drinking and administration of drug for the previous day. The thermography of face was taken using Infra-Red Imaging System (IR 2000, MEDI-CORE Co., Korea) by time interval of 15 minutes at 15 min before, just before and 15 min after, 30 min after and 45 min after acupuncture stimulation. Acupuncture was applied to the left ST36 for 30 mins. The results showed that acupuncture of ST36 significantly decreased the temperature of all the areas of facial surface comparing to those of control group. Also, it was observed that the quantities of thermal changes following acupuncture of ST36 been increased significantly at the A1, A4, A6, A7 and A9 ROIs (region of interest) comparing that of control group. Observed the thermography classified by ROI, it was clear the fact that acupuncture of ST36 could modulate the specific areas concerning to the facial pathway of Stomach Meridian, because the thermal responses following acupuncture of ST36 were specific at the A1, A2, A5 and A9 ROIs, relatively. These results suggest that acupuncture of ST36 may modulate thermal distributions and changes of facial areas concerned with Stomach Meridian.

  • Objectives : The purpose of this study was to investigate the non-surgical treatment of peripheral facial paralysis sequelae such as bell's palsy and Ramsay-hunt syndrome during last 10 years. Methods : We searched articles in the RISS, MEDLINE, CAJ from January, 2008 to June, 2018. Articles on the non-surgical treatment of bell's palsy and Ramsay-hunt syndrome sequelae were included. We extracted data about treatments, characteristics of intervention, outcomes from the included studies and classified in to 4 categories such as case studies, RCTs, nRCTs, literature reviews. Results : 132 potentially relevant studies were identified, of which 60 studies met our inclusion criteria. Of 60 included studies, 30 were case reports, 22 were RCTs, 4 were nRCTs, and 4 were reviews. China (81.8%) were the most common by country, bell's palsy(81.7%) by disease, and case reports(50%) by study type were the most common. Symptoms were lagophthalmos, asymmetry, contracture, spasm, dacryorrhea, synkinesis, paresthesia, crocodile tears mostly in the order of frequency, and these symptoms occurred at least one month after the onset of symptoms. The most common method of treatment was acupuncture, which was used in 49 studies. As the evaluation variables, the effective rate was the highest in 25, House-Brakmann grading system in 17, and Sunnybrook facial grading system in 7. In 95% of the studies, after-treatment was reported to be cured, but objectivity is low. Conclusions : This study suggests that Korean medicine such as acupuncture can play a valid role in the non-surgical treatment of peripheral facial paralysis sequelae. In the future, a systematic and well-designed clinical study is needed for treatment of peripheral facial paralysis sequelae.

  • Facial feminization surgery (FFS) incorporates aesthetic and craniofacial surgical principles and techniques to feminize masculine facial features and facilitate gender transitioning. A detailed understanding of the defining male and female facial characteristics is essential for success. In this first part of a two-part series, we discuss key aspects of the general preoperative consultation that should be considered when evaluating the prospective facial feminization patient. Assessment of the forehead, orbits, hairline, eyebrows, eyes, and nose and the associated procedures, including scalp advancement, supraorbital rim reduction, setback of the anterior table of the frontal sinus, rhinoplasty, and soft tissue modifications of the upper and midface are discussed. In the second part of this series, bony manipulation of the midface, mandible, and chin, as well as soft tissue modification of the nasolabial complex and chondrolaryngoplasty are discussed. Finally, a review of the literature on patient-reported outcomes in this population following FFS is provided.

  • Background: Facial feminization surgery and malarplasty require information concerning facial features in the malar area. Such information varies as a function of sex and race. The objectives of this study aimed to quantitatively evaluate the location of malar prominence across sexes in the Southeast Asian population, and identify sex-specific differences in malar prominence using a combination of two-dimensional (2D) computed tomography (CT) and three-dimensional (3D) CT. Methods: The location of malar prominence was evaluated in 101 Thai adults, consisting of 52 men and 49 women. This study used both 2D CT and 3D CT to achieve greater accuracy, in which 2D CT was used to measure malar distance, malar summit width, facial width, and malar summitto-facial width ratio whereas 3D CT was used to evaluate the positional relationship between the zygomatic summit and four reference points of the zygoma. Results: The malar summit was positioned more laterally in males (p< 0.01) and was more projected in females (p= 0.01). The other 2D-parameters were wider in males. The ratio between the malar summit width and facial width showed similar results for both sexes. The vertical dimension did not show any statistically significant differences; however, a higher summit position was observed in males. Conclusion: The zygomatic summit is positioned more laterally in males and is more projected in females. However, the ratio was similar, which indicates that the male cranium is larger in size. Based on the results in this study, when facial feminization surgery or malarplasty is performed on a Southeast Asian patient, the malar bone should be reduced horizontally and moved forward for better outcomes.

  • Objectives Sasang constitutional medicine is a traditional Korean medicine that classifies humans into four constitutions in consideration of individual differences in physical, psychological, and physiological characteristics. In this paper, we proposed a method to classify Taeeum person (TE) and Non-Taeeum person (NTE), Soeum person (SE) and Non-Soeum person (NSE), and Soyang person (ST) and Non-Soyang person (NSY) using a convolutional neural network with only facial images. Methods Based on the convolutional neural network VGG16 architecture, transfer learning is carried out on the facial images of 3738 subjects to classify TE and NTE, SE and NSE, and SY and NSY. Data augmentation techniques are used to increase classification performance. Results The classification performance of TE and NTE, SE and NSE, and SY and NSY was 77.24%, 85.17%, and 80.18% by F1 score and 80.02%, 85.96%, and 72.76% by Precision-Recall AUC (Area Under the receiver operating characteristic Curve) respectively. Conclusions It was found that Soeum person had the most heterogeneous facial features as it had the best classification performance compared to the rest of the constitution, followed by Taeeum person and Soyang person. The experimental results showed that there is a possibility to classify constitutions only with facial images. The performance is expected to increase with additional data such as BMI or personality questionnaire.

  • 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.
