Objectives The aim of the present study was to investigate gender difference in empathic ability and recognition of facial emotion expression in schizophrenic patients. Methods Twenty-two schizophrenic outpatients (11 men and 11 women) and controls (10 men and 12 women) performed both the scale of Empathic Quotient (EQ) and facial emotion recognition test. We compared the scores of EQ and the facial emotion recognition test among each group according to diagnosis and gender. Results We found a significant sex difference in the scores of EQ and the facial emotion recognition test in the schizophrenic patients. And there were significantly negative correlation between the score of the facial emotion recognition test and the scores of Positive and Negative Symptom Scale (PANSS) in female schizophrenic patients. However, in male schizophrenic patients, there were no significant correlations between the score of each test and the scores of PANSS. Conclusions This study suggests that the sex difference in empathic ability and facial emotion recognition would be very important in chronic schizophrenic patients. Investigation of sex effects in empathic ability and facial emotion recognition in chronic schizophrenic patients would present an important solution for constructing optimal rehabilitation program.

Purpose: Nasal bone fractures are the most common childhood facial bone fractures, with an incidence of about 39%. While taking a nasal bone x-ray is a common modality used in the emergency department, reports have expressed concerns with its low sensitivity and low specificity. Our study was aimed at comparing accuracy of physical and x-ray examination with that of facial bone computed tomography (CT). Methods: Electronic medical records (EMR) were retrospectively reviewed for patients under the age of 15 who visited our emergency department from January 2010 to December 2011with a chief complaint of nasal pain due to trauma and who had also undergone a nasal bone x-ray and facial bone CT. Patients who had not taken facial bone CT, who had been transferred, and who did not have EMR were excluded. We divided the patients into 2 groups, those who had nasal bone fractures and those without a fracture on their facial bone CT. We analyzed other parameters such as age, sex, and type of fracture to find statistical differences between the two groups. Results: A total of 209 patients were included. The patients with nasal bone fractures on their facial bone CT were older, and their traumas were more violent. Ten patients who had apparent nasal bone fractures on their facial bone CT had no definite signs of a fracture on their plain x-ray. Conclusion: Though facial bone CT is an effective modality in detecting nasal bone fractures, in evaluating younger patients suspected of having nasal bone fractures, prudent use of facial bone CT is needed to reduce unnecessary exposure to radiation.

Objectives : This research was conducted to investigate the factors that affect the level of facial nerve damage. Methods : From October 2009 to September 2013, the total number of 581 patients of Bell's palsy and Ramsay-Hunt syndrome visited Facial Palsy Center in Kyung Hee University Hospital at Gangdong for Traditional Korean and Western combined medical treatment. Of these, 453 patients of peripheral facial nerve palsy were selected for the research. After reviewing the medical records that have details of age, gender, diagnosis(Bell's palsy and Ramsay-Hunt syndrome), onset, underlying diseases(DM, HTN), and HbAlc value, the analysis on the influence factors on the level of facial nerve damage was drew out. Results : The axonal loss rate of oris branch and nasal branch were significantly higher than the axonal loss rate of frontal branch and oculi branch. In addition, the frequency of becoming a major damaged branch was also high in the oris branch nasal branch. The factors by month, weather, smoking, and alcohol did not influence EMG axonal loss rate. Male rather than female and patient with Rasmay-Hut syndrome rather than Bell's palsy had a higher axonal loss rate in all branches. Of those, front of branch of male was remarkably higher than female. Patient with DM as P/H had high axonal loss rate in all branches. Patient with HTN as P/H had high axonal loss rate in all branches except for oris branches. Patients with DM and HTN group had significantly higher value from the average of axonal loss rate than patients who are only with HTN and without DM/HTN. DM alone group had significantly higher value than patients who are without DM/HTN. However, HTN alone was not significantly high. By analysing HbAlc of the patients who were hospitalised regardless DM, axonal loss rate was high in the order of DM group, preDM group, normal group. Nevertheless, only DM group showed higher axonal rate statistically than normal group. Considering DM and HbA1c value, the patients can be divided into 4 different groups of hkDM, lkDM, hfDM and nDM. By analysing those groups, the average damaged value of the groups with diagnosis followed by treatment(lkDM, hkDM) were higher than the average rate of hfDM and statistically higher than the rate of the nDM. Conclusions : The influential factors of increasing the level of EMG damage are male(only for the frontal branch), age above sixties, HTN, DM, and HbAlc value above 6.5. Besides, the negligible factors are month, season, diagnosis, alcohol, and smoking. Further research including clinical prognosis should be conducted.

For patients with bimaxillary protrusion, significant retraction and intrusion of the anterior teeth are sometimes essential to improve the facial profile. However, severe root resorption of the maxillary incisors occasionally occurs after treatment because of various factors. For instance, it has been reported that approximation or invasion of the incisive canal by the anterior tooth roots during retraction may cause apical root damage. Thus, determination of the position of the maxillary incisors is key for orthodontic diagnosis and treatment planning in such cases. Cone-beam computed tomography (CBCT) may be useful for simulating the post-treatment position of the maxillary incisors and surrounding structures in order to ensure safe teeth movement. Here, we present a case of Class II malocclusion with bimaxillary protrusion, wherein apical root damage due to treatment was minimized by pretreatment evaluation of the anatomical structures and simulation of the maxillary central incisor movement using CBCT. Considerable retraction and intrusion of the maxillary incisors, which resulted in a significant improvement in the facial profile and smile, were achieved without severe root resorption. Our findings suggest that CBCT-based diagnosis and treatment simulation may facilitate safe and dynamic orthodontic tooth movement, particularly in patients requiring maximum anterior tooth retraction.

Facial esthetics is one of the most important goal of the orthodontic treatment and main concern of many patients. Facial esthetics should be considered in orthodontic diagnosis and treatment planning. Prediction of soft tissue profile changes after orthodontic tooth movement should be considered as well. The purpose of this study was to find out the effect of orthodontic treatment on lip profile in adult patient. The pre and post treatment cephalometric roentgenograms of 87 female adult with bimaxillary protrusion were used to analyze lip profile change. All subjects were treated with four bicuspids extraction. Obtained results were as follows . 1. Lip thickness changes after incisor retraction showed different patterns according to areas of the lip. The thickness of the red lip area showed 2.78 mm increase in average. In contrast the thickness of the cutaneous area showed 0.65 - 0.7 mm decrease according to the different cutaneous areas. 2. The length of the red lip area decreased(1.3mm) after incisor retraction. 3. The length of the cutaneous lip area increased(2.9mm) after incisor retraction.

A Brazilian girl aged 14 years and 9 months presented with a chief complaint of protrusive teeth. She had a convex facial profile, extreme overjet, deep bite, lack of passive lip seal, acute nasolabial angle, and retrognathic mandible. Intraorally, she showed maxillary diastemas, slight mandibular incisor crowding, a small maxillary arch, 13-mm overjet, and 4-mm overbite. After the diagnosis of severe Angle Class II division 1 malocclusion, a mandibular protraction appliance was placed to correct the Class II relationships and multiloop edgewise archwires were used for finishing. Follow-up examinations revealed an improved facial profile, normal overjet and overbite, and good intercuspation. The patient was satisfied with her occlusion, smile, and facial appearance. The excellent results suggest that orthodontic camouflage by using a mandibular protraction appliance in combination with the multiloop edgewise archwire technique is an effective option for correcting Class II malocclusions in patients who refuse orthognathic surgery.

Study of dentofacial structure relationships relative to TMJ internal derangement is required to increase the predictability of TMJ internal derangement. But few studies have been reported. The purpose of this study is to reveal any correlation of dentofacial characteristics with TMJ internal derangement by lateral cephalometric analysis. Patients were devided into two groups. (1) Symptomatic patients with TMJ internal derangement (2) Asymptomatic volunteers with no TMJ internal derangement. Twenty symptomatic patients with TMJ internal derangement(7male, 13female) were selected from our clinic and had undergone a standarized clinical examination, panorama, transcranical view, TMJ tomography. Twenty asymptomatic volunteers(9male, 11female) were selected from our clinic with no pain, no limitation of motion. All subjects had undergone lateral cephalometric analysis. The results were obtained as follows. 1. No significant difference between ID and normal group is detected in cranial base. 2. Maxilla position of ID group is located more posterioly than normal group. 3. Mandible position of ID group is located more posteriorly than normal group and facial profile is hyperdivergent. 4. Posterior facial height of ID group is less than normal group thus facial profile is hyperdivergent. The patients, as mentioned, have a high prevalance of ID thus it should be careful in TMJ ID diagnosis and treatment.

Posttraumatic pseudoaneurysm of the superficial temporal artery is very rare and occurs secondary to trauma. Clinical diagnosis is based on past history of trauma and physical examination and can be confirmed by duplex ultrasonogram, digital subtraction angiography, CT and MRI. Ligation of proximal and distal ends of the superficial temporal artery and excision of the pseudoaneurysm has been the standard treatment. Compressive therapy, endovascular coil embolization, percutaneous thrombin injection under ultrasound guidance have been reported as alternative treatment methods. When surgical excision of the superficial temporal artery pseudoaneurysm is performed, surgeon must be concerned about the anatomical relation between superficial temporal artery and temporal branches of the facial nerve. In this article, we report a rare case of superficial temporal artery pseudoaneurysm with some review of the literatures about anatomical relation between superficial temporal artery and temporal branches of facial nerve.

The ankylosis of temporomandibular joint occured by several causes directly developes TM joint disfunction, In cases with prolonged condylar ankylosis, especially at growing age the condylar ankylosis evokes malfunction of growth center area, and then developes the abnormal facial morphology and malocclusion. Therefore it must be cured. Almost authors have agreed to the necessity of surgical correction of the TMJ anylosis. but they did not decide the one surgical method to get the best result. The Tx. method suggested by many authors are the using interposition after resection of condyle to remain a lever of 3rd class in Mn. kinetics, the autogenous condylar graft and the alloplastic condylar graft. Some authors have got the satisfied results only with the condylectomy of the involved TMJ. This study also operated only the detachment of fibrous adhesion on ankylosed condylar side and then established occlusion in the case with the unilateral TMJ ankylosis and fibrous joint adhesion and facial asymmetry evoked after the fracture of condylar head at early age. This study got a improved mouth opening and a stable postsurgical result after 1 year. Also, this study reviewed many author's study about the chanracteristics, etiology, diagnosis and Tx. method for the ankylosis of TMJ.
