Funnel chest is the most common deformity of the sternum. It is characterized by a funnel shaped depression of the sternum with sharp angulation and lengthening of the costal cartilages, with the result that the cartilages point posteriorly. We have experienced with eight cases of funnel chest for 2 years recently, and they were corrected by the method of Ravitch operation with or without Kirschner`s wire. The postoperative course was uneventful. And now we report these with literature review.

This is a case report of correction of posttraumatic diplopia and enophthalmos using autogenous composite conchal cartilage and temporal fascia. The results are as follows. 1. Diplopia and enophthalmos may be persistent complications in zygomatic complex fracture. 2. The concha is a reservior of autogenous cartilage which leaves no cosmetic and functional deformity in reconstruction of orbital floor. 3. Warpping the cartilage in temporal fascia may serve to increase implant stability and get graft with smooth edge. 4. Donor incision lines are well hidden within the scalp and in auriculocephalic fold.

Purpose: A cranioremodeling helmet for correcting plagiocephaly was recently developed. However, no discrete objective methods to evaluate how the deformity is being corrected have been developed. We have established an easy and cost-effective method that can be used not only to show the correction process, but can also be used by physicians to assess the degree of plagiocephaly two-dimensionally. Methods: For two-dimensional evaluation, a length of malleable memory wire (2 mm in diameter) resembling "Sun-Wukong's headband" was placed on the patient's head. The wire around the patient's head was positioned on a plane including points 1 cm above the eyebrow and 1 cm above the auricle. The wire was placed on a sheet of paper and the outline was marked using pens of various colors during each visit. The degree of plagiocephaly correction could then be shown to the patient's parents at every consultation. Results: The method established by the present study easily shows the horizontal cross-section transformation of the head, illustrates plagiocephaly correction by the helmet, and shows the degree of correction in a two-dimensional manner. Conclusion: A soft-shell helmet is widely used for correcting plagiocephaly. However, evaluating the effectiveness of the helmet has been determined in a subjective manner, and a more objective method is now in demanded. Our study found that a "Sun-Wukong's headband" wire can accurately measure two-dimensional changes. Future studies will be required to identify landmarks needed for assessing plagiocephaly correction.

Study Design: Retrospective review. Purpose: To detect the effect of cannulated (poly-axial head) and solid (mono-axial head) screws on the local kyphotic angle, vertebral body height, and superior and inferior angles between the screw and the rod in the surgical management of thoracolumbar fractures. Overview of Literature: Biomechanics studies showed that the ultimate load, yield strength, and cycles to failure were significantly lower with cannulated (poly-axial head) pedicle comparing to solid core (mono-axial head). Methods: The medical charts of patients with thoracolumbar fractures who underwent pedicle screw fixation with cannulated or solid pedicle screws were retrospectively reviewed; the subjects were followed up from January 2011 to December 2015. Results: Total 178 patients (average age, $36.1{\pm}12.4years$; men, 142 [84.3%]; women, 28 [15.7%]) with thoracolumbar fractures who underwent surgery and were followed up at Hamad Medical Corporation were classified, based on the screw type as those with cannulated screws and those with solid screws. The most commonly affected level was L1, followed by L2 and D12. Surgical correction of the local kyphotic angle was significantly different in the groups; however, there was no significant difference in the loss of correction of the local kyphotic angle of the groups. Surgical correction of the reduction in the vertebral body height showed statistical significance, while the average loss of correction in the reduction of the vertebral body height was not significantly different. The measurement of the angles made by the screws on the rods was not significantly different between the cannulated (poly-axial head) and solid (mono-axial head) screw groups. Conclusions: Solid screws were superior in terms of providing increased correction of the kyphotic angle and height of the fractured vertebra than the cannulated screws; however, no difference was noted between the screws in the maintenance of the superior and inferior angles of the screw with the rod.

The pectus excavatum is the most common deformity of chest wall. The most common cause of surgical correction is cosmetic problem. From January 1981 to July 1996, 24 patients had undergone surgery for pectus excavatum and they were corrected by Ravitch operation(n=4) or modified Wada operation(n=20) respectively. We analyzed each surgical cases according to age, sex, chief complaint, degree of deformity, EKG findings, complications and satisfaction degree of patient. In some cases, we measured Welch index preoperatively and postoperatively. The postoperative complications were wound infection in two, pneumothorax in two and reccurrence in one. The average value of Welch index was significantly improved from 5.86$\pm$0.51 preoperatively to 4.10$\pm$0.51 postoperatively(P<0.05). The results by Humphreys' criteria were satisfiable in 88%(excellent 71%, good 17%). The findings of this study suggest that surgical correction of pectus excavatum with modified Wada rocedure and submammary s in incision is effective method in physical and psychiatric aspect.

The need to assess preoperative psychological characteristics of orthognathic surgery patients has recently been recognized. Fifty six patients were involved in this study, they were investigated in the preoperative psychosocial aspects. Korean Version Eysenk Personality Questionaire and Korean Version Tennessee Self-Concept Scale were used for psychological test. The results were as follows : 1. There was no significant difference of sex and age in the personality dimension, the selfconcept scale, and the preoperative tests(P>0.05). 2. 37% of subjects showed phonetic problem, 60% masticatory problem and 56% social problem for facial deformity. The first choice was the face in the order of correction for mastication, phonation and face. And 83% of the subjects forecasted the change in their face after surgical correction, The answer was generally vague. 64% of the subjects expected their personality to become more lively as a result of their operation. 3. Total positive self score and personal self score were less improved in the groups with high scores of toughmindness and neuroticism(P<0.05), degree of suffering was increased in the group with high scores of neuroticism(P<0.05). 4. Degree of subjective deformity, self-consciousness, and degree of dissimilarity were more improved in the group of intraversion, there was a significant correlation with degree of dissimilarity in the group with high score of toughmindness(r=-.64, P<0.05). 5. There was a significant correlation with the forecast of change in the groups with high score in extraversion(r=.59, P<0.01) and with low score in neuroticism(r=-.39, P<0.05).

Background Microtia with constricted features is characterized by a short helical length of variable severity, upper antihelical or scaphal deficiency, and a downfolded upper ear. No consensus has been reached regarding the most appropriate surgical method for this condition. In this study, we aimed to introduce a simple and safe surgical method for the correction or reconstruction of upper helix ear deformities. Methods Between February 2011 and June 2014, eight patients with microtia with constricted upper helix ear deformity underwent reconstruction of the ear deformity. The upper ear helical framework was constructed by carving and curving the eighth rib cartilage harvested from the ipsilateral chest wall, covering this cartilage with a superficial temporal fascial flap, and adjusting the skin graft to align with the ear contour. To evaluate their satisfaction, patients were asked to complete a questionnaire regarding ear shape, symmetry, position, color, and overall outcome scored on a 5-point scale at 12 months postoperatively. Results None of the patients experienced severe complications in the reconstructed ear. The preoperative and postoperative vertical ear length ratios were 0.88 and 1.02, respectively. And the mean patient satisfaction scores for shape, symmetry, position, color, and overall outcome were 4.2, 4.5, 4.7, 4.4, and 4.6 out of 5 points, respectively. All patients expressed a high level of satisfaction at 12 months postoperatively. Conclusions Our technique provides a good alternative method for the reconstruction of moderate constricted upper helix ear deformities in patients who meet the surgical indications with satisfactory outcomes and few complications.

Objective : A thoracolumbar burst fracture is usually unstable and can cause neurological deficits and angular deformity. Patients with unstable thoracolumbar burst fracture usually need surgery for decompression of the spinal canal, correction of the angular deformity, and stabilization of the spinal column. We compared two struts, titanium mesh cages (TMCs) and expandable cages. Methods : 33 patients, who underwent anterior thoracolumbar reconstruction using either TMCs (n=16) or expandable cages (n=17) between June 2000 and September 2011 were included in this study. Clinical outcome was measured by visual analogue scale (VAS), American Spinal Injury Association (ASIA) scale and Low Back Outcome Score (LBOS) for functional neurological evaluation. The Cobb angle, body height of the fractured vertebra, the operation time and amount of intra-operative bleeding were measured in both groups. Results : In the expandable cage group, operation time and amount of intraoperative blood loss were lower than that in the TMC group. The mean VAS scores and LBOS in both groups were improved, but no significant difference. Cobb angle was corrected higher than that in expandable cage group from postoperative to the last follow-up. The change in Cobb angles between preoperative, postoperative, and the last follow-up did not show any significant difference. There was no difference in the subsidence of anterior body height between both groups. Conclusion : There was no significant difference in the change in Cobb angles with an inter-group comparison, the expandable cage group showed better results in loss of kyphosis correction, operation time, and amount of intraoperative blood loss.

Ankyloglossia, or tongue-tie, is a congenital condition which occurs as a result of fusion between the tongue and the floor of the mouth. Ankyloglossia often results in malocclusion with an anterior "open bite" deformity, early prognathism, swallowing problem, speech disorder, and periodontal problem. Generally lingual frenectomy is used for treatment of ankyloglossia, but incomplete operation and simple frenectomy may produce a scar contracture resulting in a more deformed ankyloglossia than was present initially. The Z-plasty is used for the correction of scar contractures and the replacement of missing tissue and this procedure is ideally suited for the treatment of an ankylosed frenum. Most authors advise postponement of any decision for surgical correction of tongue-tie until the age of 4 years, unless the child is having much difficulty with sucking or swallowing. We treated 4 patients with ankyloglossia using Z-plasty technique. As a result, we found out that it was effective for correction of movement limitation of tongue, prevention of relapse. Further, periodic check ups are needed for evaluation of relapse, improvement of speech, and other functions of the tongue.
