Nowadays, plastic surgical operations are increasingly being performed in Korea. We have gained added interest in this because some professional pictures contain plastic surgery in their venue. In the films, we intend to see the recognition of society for plastic surgeons and which field of plastic surgery. The list of movies for analysis were 'Plastic Beauty (1975)', 'Penthouse Elephant (2005)', '200 Pounds Beauty (2006)', 'Cinderella (2006)', and 'Time (2006)'. The TV dramas were 'She is looking (2005)', 'Lovers (2006-2007)', and 'Before & After Plastic Surgery Clinic (2008)'. Films were analyzed according to the following: the chief complaints and names of the operations, character of plastic surgeons, result of the operation and its possibility in reality, and its effect of plastic surgery on the life of the patients. Most of the film contained facial transplantation or the change of the face or body different from the original shape. Character type of the plastic surgeons was mostly medical realism, rather than ideal humanism. Most of the plastic surgeons have capability as a doctor; however, some of them had extramarital affairs. The surgery was successful in most of the cases, but were the patients happy with the results? This was not the case in the movies. In only one movie, '200 Pounds Beauty', the patient became happy; rest of them were eminently unhappy with the outcome. Why the discrepancy? It is difficult to analyze the minds of the people in the films, but considering that the majority of the characters in the films were rather unsavory, one may deduce that a crooked mind functions differently. Perhaps it is too much to hope for a day that will come when we will see a film that portrays the mental anguish that accompanies each and every procedure the Korean plastic surgeons make.

Purpose: A descriptive study was conducted to examine the levels of distress, state anxiety, and physiologic responses in postoperative patients under patient controlled analgesia (PCA), and to determine correlations among the variables. Method: The study sample included women who underwent an elective hysterectomy procedure or other gynecologic surgeries(N=100). Subjective distress was assessed by visual analog scales around 8 hours postoperatively. Trained nurses collected objective distress data through observation of subject's behavior and vital signs. Data were analyzed with frequencies, percentages, means, Pearson correlation coefficients, ANOVA, and the Scheffe post test using SPSS/PC 11.0. Result: Subjective distress, objective distress, and state anxiety scores were relatively low, except pain scores(5.31 out of 10.0) among sub-scales of subjective distress. Women who had a total abdominal hysterectomy showed significantly higher levels of both subjective distress and state anxiety than those after a minor gynecologic surgery. In relationships among variables, subjective distress correlated positively with postoperative state anxiety, but not with the amount of analgesic medication, verified by further analysis on sub-scales of subjective and objective distress. The higher the levels of state anxiety, the higher the levels of tension, dyspnea, facial change, and systolic blood pressure observed. Conclusion: Regardless of effective pain management, most postoperatively experienced distress in gynecological patients was derived from surgery associated anxiety and pain. Specific psychological strategies should be established as well for those with high levels of state anxiety to facilitate prompt recovery.

Purpose: This study considered the effects and proper treatments of mandibular condyle fractures by comparing clinical differences and complications according to analysis and treatment plan. Methods: From September 2007 to August 2010, patients who were diagnosed with condylar fracture and monitored for more than 3 months were selected. Cases were divided in a reductive manner and evaluated by type and period of intermaxillary fixation (IMF), status of occlusion and trismus according to the Spiessle/Schroll method. A total 50 patients were examined. Results: The number of the unilateral condyle fractures was 45 and 30 patients had multiple fractures. Type of fracture was categorized by the Spiessle/Schroll method. There were 21 patients with type I, 11 patients with type II, 3 patients with type 3, 10 patients with type V and 5 patients with type VI; there were no patients with a type IV fracture. 11 patients were operated on with open reduction. Among them, 9 patients were type II and 2 patients were type I. For type I patients, an intra-oral approach was conducted with an endoscope and trocar. For 3 of the type II patients, an retromandibular approach was conducted and for the rest of the type II patients, the same approach as type I was used. The periods of IMF were 2.36 weeks (mean) in open reduction group and 2.9 weeks (mean) in closed reduction group and the total mean period is 2.78 weeks. All patients had stable occlusion after removing the IMF. Trismus occurred in 1 patient for open reduction and 5 patients for closed reduction. Facial nerve palsy was observed in one patient postoperatively that resolved after 6 months. Conclusion: In this study, similar prognosis was shown after an open and closed reduction was conducted. Therefore, treatments need to be planned depending on the degree of condyle fracture and the amount of displacement. Additionally, the period of IMF could be shortened with open reduction.

Objective: This study aimed to analyze the correlation of horizontal and sagittal planes used in two-dimensional diagnosis with lip canting by using three-dimensional (3D) analysis. Methods: Fifty-two patients (25 men, 27 women; average age: 24 years) undergoing treatment for dentofacial deformity were enrolled. Computed tomography images were acquired, and digital imaging and communication in medicine files were reconstructed into a 3D virtual model wherein horizontal and sagittal craniofacial planes were measured. Subsequently, the correlations of lip canting with these horizontal and sagittal planes were investigated. Results: The mandibular symmetry plane, the occlusal plane, Camper's plane, the mandibular plane, Broadbent's plane, and the nasal axis plane were correlated with the amount of lip canting (Pearson's correlation coefficients: 0.761, 0.648, 0.556, 0.526, 0.438, and 0.406, respectively). Planes associated with the lower part of the face showed the strongest correlations; the strength of the correlations decreased in the midfacial and cranial regions. None of the planes showed statistically significant differences between patients with clinical lip canting (> 3°) and those without prominent lip canting. Conclusions: The findings of this study suggest that lip canting is strongly correlated with the mandibular symmetry plane, which includes menton deviation. This finding may have clinical implications with regard to the treatment of patients requiring correction of lip canting. Further studies are necessary for evaluating changes in lip canting after orthognathic surgery.

Purpose: As the interest and demand for esthetics grow up with medical development, the number of patients who want to correct dentofacial deformities by orthognathic surgery has increased. And the success of orthognathic surgery is dependent upon satisfaction of patients in great measure. Therefore the purpose of this study is to examine functional disability, sensory disturbance and esthetic satisfaction of the patients after orthognathic surgery. Material and methods: Among 89 patients who orthognathic surgery was performed at Seoul National University Bundang Hospital during the period from July 2003 to July 2008, 46 patients were considered in the study. Patients were surveyed with questionnaires and visual analogue scale(VAS) which author has designed. The analysis and comparison were performed according to gender, follow up span, and type of surgery based on answer of questionnaires. Results and conclusions: Total satisfaction rate was 76%. And there was statistical significant difference between subjective evaluation of facial esthetics before the surgery and that of after surgery(p<0.05). Differences in occurrence of functional disability, sensory disturbance between groups were not observed. In conclusion, the operator should understand the postoperative self-satisfaction of the patients and complications. If we can communicate with the patients before operation. patients' satisfaction rate will increase after operation.

Objectives: This paper proposes Han's ratio as an objective and quantitative comparative result obtained from pre and postoperative data in patients with a mandibular angle reduction. Materials and Methods: Thirty patients, 12 men and 18 women, who visited the Department of Oral and Maxillofacial Surgery with the chief complaints of skeletal mandibular prognathism and prominent mandibular angle were selected. The subjects were classified into 3 groups according to the types of surgical procedures involved. Group A consisted of patients who underwent mandibular angle resection and mandibular setback. Group B was comprised of patients with mandibular angle resection, mandibular setback and genioplasty. Group C consisted of patients with mandibular angle resection, mandibular setback, Le Fort I osteotomy, and genioplasty. The landmarks placed in pre and postoperative frontal photographs were used to obtain the Han's ratio in each group. The Han's ratios were compared pre- and postoperation and according to the surgical techniques applied. Results: Of the 3 groups who had undergone a mandibular angle resection, all showed a statistically significant increase in Han's ratio. On the other hand, there was no statistically significant difference based on the surgical techniques used. Conclusion: The ratio of the lateral lower face proposed in this study is a potential indicator of postoperative esthetic enhancement in mandibular angle reduction surgery.

Background A blow-out fracture is one of the most common facial injuries in midface trauma. Orbital wall reconstruction is extremely important because it can cause various functional and aesthetic sequelae. Although many materials are available, there are no uniformly accepted guidelines regarding material selection for orbital wall reconstruction. Methods From January 2007 to August 2012, a total of 78 patients with blow-out fractures were analyzed. 36 patients received absorbable mesh plates, and 42 patients received titanium-dynamic mesh plates. Both groups were retrospectively evaluated for therapeutic efficacy and safety according to the incidence of three different complications: enophthalmos, extraocular movement impairment, and diplopia. Results For all groups (inferior wall fracture group, medial wall fractrue group, and combined inferomedial wall fracture group), there were improvements in the incidence of each complication regardless of implant types. Moreover, a significant improvement of enophthalmos occurred for both types of implants in group 1 (inferior wall fracture group). However, we found no statistically significant differences of efficacy or complication rate in every groups between both implant types. Conclusions Both types of implants showed good results without significant differences in long-term follow up, even though we expected the higher recurrent enophthalmos rate in patients with absorbable plate. In conclusion, both types seem to be equally effective and safe for orbital wall reconstruction. In particular, both implant types significantly improve the incidence of enophthalmos in cases of inferior orbital wall fractures.

Purpose: Reduction malarplasty is a popular aesthetic surgery for contouring wide and prominent zygoma. However a few patients complain postoperative results and want to revise the midfacial contour. We analyzed the etiology of unfavorable results and treated unsatisfied midfacial contours after reduction malarplasty. Methods: Total 53 patients were performed secondary operation for correction of unfavorable results after primary reduction malarplasty from elsewhere. Midfacial contour was evaluated with plain films and three-dimensional computed tomography. Unfavorable midfacial contours were corrected by secondary malarplasty. Flaring of zygomatic arch was reduced with infracturing technique and prominent zygomatic body was reduced with shaving. Drooped or displaced zygoma complex has been suspended to higher position and fixed with interosseous wiring. As adjuvant procedure, autologous fat injection has been performed in the region of depressed zygomatic body region. Results: The etiology of unfavorable midfacial contour after reduction malarplasty was classified into 7 categories: undercorrection of zygomatic arch(n=8), undercorrection of zygomatic arch and undercorrection of zygomatic body(n=6), undercorrection of zygomatic arch and overcorrection of zygomatic body(n=28), overcorrection of zygomatic body(n=3), simple asymmetry(n=4), malunion(n=2) or nonunion(n=2). Slim and balanced malar contour was achieved with treatment. And most of the patients were satisfied with the results of the surgery. Conclusion: To prevent the unfavorable results after reduction malarplasty, complete analysis of facial contour, choice of appropriate operation technique, precise osteotomy under direct vision, and security of zygoma position are important.
