Background Although plastic surgeons daily encounter various facial tumors in the field, reports limited on face are scarce. In our study, we want to provide basic epidemiologic data to help clinicians to decide the proper management for their patients. Methods We retrospectively reviewed the medical records of patients including age and gender, location and size of the tumor, histopathologic result, recurrence, type of anesthesia and any associated disorders who had undergone a surgical removal of their facial tumors and received the histopathologic report in the same institution between January 2009 and October 2012. Results One hundred eighty-nine patients with 203 non-melanocytic benign tumors were included. The most frequent site of tumors was the central subunit of the forehead, followed by the lateral subunit of the cheek and the auricular unit. Of 36 different histopathologic results, the epidermal cyst was most frequent, followed by lipoma, pilomatricoma and osteoma. Statistical analysis showed that males were dominant in the epidermal cyst and lipoma groups. While, females were dominant in the osteoma and pilomatricoma groups. No associations were found between lesions and other diseases. Conclusions Our study is the at most specific and concentrated study on non-melanocytic benign tumors of the face. We expect the epidemiologic data of our study may help plastic surgeons who are confronted with so many facial lesions in the field to decide on the most proper management for their patients.

Obejectives : To investigate the clinical effect of electroacupuncture and bee venom acupuncture for benign prostatic hyperplasia(BPH) symptoms. Methods : Among 39 outpatients who were treated at a BPH clinic, 8 were finally selected for analysis by charts-review, retrospectively. They were treated by electroacupuncture and bee venom acupuncture more than 3 times. We estimated the effectiveness of the treatments by using the International Prostate Symptom Score (IPSS) questionnaire and checking their nocturia frequency. On the basis of these variables, we analyzed the statistical significations of symptom improvements. Results : Among 8 patients, the IPSS and nocturia frequency showed significant improvement after the final treatment compared with baseline (P = .0078, P = .0078). The IPSS significantly decreased even after the 1st treatment and also after the 2nd treatment compared with the baseline (P = .0078, P = .0078). The IPSS at post final-treatment, post 1st- and post 2nd treatment also showed significant improvement compared with IPSS at baseline in 6 severe symptomatic patients(P = .031, P = .031, P = .031). Nocturia frequency decreased after the 1st treatment compared with baseline and showed significant improvement between baseline and post 2nd treatment (P = .0078). Conclusions : In a retrospective and cross-sectional study investigating the clinical effects of electroacupuncture and bee venom acupuncture on BPH, these treatments proved to have significant therapeutic effects, particularly for various symptoms involving frequent nocturia.

Purpose: Because of traffic accidents and many criminal violences, the incidence of facial trauma has been increasing not only in adults but also in children. We planed this study to introduce our experience about pediatric blow out fracture and provide more information. Methods: We made retrospective study in 76 children with blow out fracture from January 2001 to September 2005 by retrospective chart review including detailed preoperative and postoperative evaluations, age, sex, cause, symptom and sign, and their post-operative complications. Results: Among our patients, 69 were male and 7 were female. The ages ranged from 7 to 18 years, which shows the greatest incidence of blow out fracture. Physical violence(46%) was the most common cause in this group and was followed by vehicle accident(28%), and fall down accident(17%). Left side(64%) showed slightly more incidence than right side(36%), but there were no statistical importance. Ecchymosis(88%) was the most common symptom and followed by periorbital swelling(68%) and diplopia(30%). 30 patients was diagnosed with another facial bone fracture and nasal bone(51%) was the most common associated facial bone fracture. Fourty four Patients(60%) got an orbital wall reconstruction in 7 days after trauma. After the operation, only 3 patients(4%) suffered from diplopia postoperative 3 month, and resolved in 4 years. Conclusion: The incidence of blow out fracture in children has been increasing every year, and violence has become more important etiology of pediatric blow out fracture and public and private education institutions were the most common place that blow out fracture originated. Accurate diagnosis and careful treatment plans are important in pediatric blow out fracture.

Objectives The purpose of this study was to compare the effect of supine JS cervical therapy and muscle release/strengthening technique in patients with acute neck pain caused by traffic accidents. Methods We studied 42 patients with acute neck pain caused by traffic accidents from July 1, 2019 to November 30, 2019. The study was conducted as a retrospective study which analyzes the patient's medical records. 21 patients (group A) had received supine JS cervical therapy and 21 patients (group B) had received muscle release/strengthening technique. We used the neck disability index (NDI) and visual analog scale (VAS) to evaluate improvements in symptoms and pain, and used the five point Likert scale to evaluate patient's satisfaction with chuna manual therapy. In each group, we compared the NDI and VAS of hospitalization day to those of 5 days later. Then we compared the NDI, VAS variation and five point Likert scale between the groups. Statistical analysis was conducted using the IBM SPSS for windows 25.0. Result Both group A and group B showed a statistically significant decrease in the NDI and VAS on the 5th day of hospitalization. In group A, there was a statistically significant decrease in the NDI compared to group B. The VAS and Five Point Likert Scale decrease was greater in group A than in group B, but the difference was not statistically significant. Conclusion We found that using supine JS cervical therapy may be more effective than muscle release/strengthening technique in acute stage after traffic accidents.

Objectives: This study conducted a retrospective review to compare the effectiveness of herbal medicine, while confirming the effectiveness of Korean medicine (KM) in traffic accidents (TA). Methods: We investigated the medical records of TA patients who were hospitalized at Muuido Korean medicine hospital from January 2016 to June 2018 retrospectively. Medical records included general characteristics (Gender, age), TA & treatment-related information (Collision type, chief complaint, hospitalization period, and herbal medicine prescription), and clinical scales (Five-scale improvement, numerical rating scale (NRS)). Statistical analysis was performed for data distribution and effectiveness comparison. Results: 755 TA patients showed 0.78:1 gender ratio. 20-50s years old, rear collision, pain in the cervical and lumbar spine, and hospitalization period within 14 days were the majority. KM improved 83.18% of 755 TA patients' symptoms and ROM over 'improvement' level, which indicated 30-70% improvement. With common KM treatments including acupuncture, cupping, heat therapy, and manipulation therapy, TA patients received various herbal medicines and herbal medicine for breaking severe blood stasis (Tongdo-san) showed improvement in both five-scale improvement and NRS change at the same time. Conclusions: We could confirm the effectiveness of KM, particularly herbal medicine in TA. It would be necessary to develop new herbal medicines such as Tongdo-san to treat TA-related symptoms.

Objectives To observe the pain reduction effect of Korean medical treatment combined with supine JS cervical therapy on neck pain and headache caused by whiplash injury. Methods The medical records of 30 patients suffering from neck pain and headache caused by traffic accidents from August 1, 2020 to October 30, 2020 were studied. 15 patients receiving supine JS cervical therapy combined with Korean medical treatment were assigned to group A and another 15 patients receiving Korean medical treatment but without Chuna therapy were assigned to group B. The following patient data were analyzed retrospectively - age, sex, and number of admission days, neck pain and headache visual analogue scale (VAS), and neck disability index (NDI). Statistical analysis was conducted using IBM SPSS 25.0. for Windows. A p-value≤0.05 was considered to be statistically significant. Results Both neck pain and headache VAS score in group A and B showed a statistically significant decrease. The changes in neck pain and headache VAS score in group A was statistically significant higher compared to those of group B. NDI in group A showed a statistically significant decrease, but NDI in group B did not decreased statistically significant. Conclusions Korean medicine treatment effectively reduces neck pain and headache. Especially, the pain reduction effect is better in patients receiving Korean medicine treatment combined with supine JS cervical therapy than in those receiving Korean medicine treatment without supine JS cervical therapy.

Objective: The aim of this retrospective study was to assess the midfacial soft tissue changes following maxillary expansion using micro-implant-supported maxillary skeletal expanders (MSEs) in young adults by cone-beam computerized tomography (CBCT) and to evaluate the correlations between hard and soft tissue changes after MSE usage. Methods: Twenty patients (mean age, 22.4 years; range, 17.6-27.1) with maxillary transverse deficiency treated with MSEs were selected. Mean expansion amount was 6.5 mm. CBCT images taken before and after expansion were superimposed to measure the changes in soft and hard tissue landmarks. Statistical analyses were performed using paired t-test and Pearson's correlation analysis on the basis of the normality of data. Results: Average lateral movement of the cheek points was 1.35 mm (right) and 1.08 mm (left), and that of the alar curvature points was 1.03 mm (right) and 1.02 mm (left). Average forward displacement of the cheek points was 0.59 mm (right) and 0.44 mm (left), and that of the alar curvature points was 0.61 mm (right) and 0.77 mm (left) (p < 0.05). Anterior nasal spine (ANS), posterior nasal spine (PNS), and alveolar bone width showed significant increments (p < 0.05). Changes in the cheek and alar curvature points on both sides significantly correlated with hard tissue changes (p < 0.05). Conclusions: Maxillary expansion using MSEs resulted in significant lateral and forward movements of the soft tissues of cheek and alar curvature points on both sides in young adults and correlated with the maxillary suture opening at the ANS and PNS.

Objectives: The purpose of this retrospective study was to evaluate the variables associated with length of stay (LOS), hospital costs, intensive care unit (ICU) use, and treatment outcomes in patients hospitalized for maxillofacial infections at a tertiary medical center in South Korea. Materials and Methods: A retrospective chart review was conducted for patients admitted for treatment of maxillofacial infections at Dankook University Hospital from January 1, 2011 through September 30, 2020. A total of 390 patient charts were reviewed and included in the final statistical analyses. Results: Average LOS and hospital bill per patient of this study was 11.47 days, and ₩4,710,017.25 ($4,216.67), respectively. Of the 390 subjects, 97.3% were discharged routinely following complete recovery, 1.0% expired following treatment, and 0.8% were transferred to another hospital. In multivariate linear regression analyses to determine variables associated with LOS, admission year, infection side, Flynn score, deep neck infection, cardiovascular disease, admission C-reactive protein (CRP) and glucose levels, number and length of surgical interventions, tracheostomy, time elapsed from admission to first surgery, and length of ICU stay accounted for 85.8% of the variation. With regard to the total hospital bill, significantly associated variables were age, type of insurance, Flynn score, number of comorbidities, admission CRP, white blood cell, and glucose levels, admission temperature, peak temperature, surgical intervention, the length, type, and location of surgery, tracheostomy, time elapsed from admission to first surgery, and length of ICU use, which accounted for 90.4% of the variation. Age and ICU use were the only variables significantly associated with unfavorable discharge outcomes in multivariate logistic regression analysis. Conclusion: For successful and cost-effective management of maxillofacial infections, clinicians to be vigilant about the decision to admit patients with maxillofacial infections, perform appropriate surgery at an adequate time, and admit them to the ICU.

Background: The purpose of this study was to identify predictors of the time from initial presentation to total shoulder arthroplasty (TSA) in patients with primary glenohumeral osteoarthritis (OA) and rotator cuff (RTC) arthropathy who were conservatively managed with corticosteroid injections. Methods: We conducted a retrospective cohort study of patients who underwent TSA from 2010 to 2021. Kaplan-Meier survival analysis was used to estimate median time to TSA for primary OA and RTC arthropathy patients. The Cox proportional hazards model was used to identify significant predictors of time to TSA and to calculate hazard ratios (HRs) with 95% confidence intervals (CIs). Statistical significance was set at P<0.05. Results: The cohort included 160 patients with primary OA and 92 with RTC arthropathy. In the primary OA group, median time to TSA was 15 months. Significant predictors of shorter time to TSA were older age at presentation (HR, 1.02; 95% CI, 1.00-1.04; P=0.03) and presence of moderate or severe acromioclavicular joint arthritis (HR, 1.45; 95% CI, 1.05-2.01; P=0.03). In the RTC arthropathy group, median time to TSA was 14 months, and increased number of corticosteroid injections was associated with longer time to TSA (HR, 0.87; 95% CI, 0.80-0.95; P=0.003). Conclusions: There are distinct prognostic factors for progression to TSA between primary OA patients and RTC arthropathy patients managed with corticosteroid injections. Multiple corticosteroid injections are associated with delayed time to TSA in RTC arthropathy patients.

Objectives: This study analyzed laboratory serum data results before and after patients took herbal medicine to confirm the clinical safety of herbal medicine. In addition, in the event of liver damage, the case was analyzed to confirm the characteristics of liver damage and the possibility of liver damage caused by herbal medicine. Methods: A retrospective chart review of the effects of herbal medicine on liver function in patients diagnosed with functional dyspepsia was conducted. The electronic medical records of 128 patients in a single hospital were reviewed. Results: The statistical analysis revealed a statistically significant decrease in liver function-related laboratory serum data after taking herbal medicine (p<0.05). In addition, among 128 patients, there were two cases of drug-induced liver injury (DILI) (1.56%). Conclusion: Taking herbal medicine prescribed by experts does not significantly affect liver function in patients with functional dyspepsia. Rather, the liver levels of the subjects showed a significant decrease after taking herbal medicine. To support these results, further large-scale multicenter prospective studies are necessary.
