Objective: Osteotomies are required for the mobilization of spinal segments in patients with revisional scoliosis surgery with a fusion mass; however, only a few techniques have shown efficacy and safety, and their mid- and long-term outcomes remain unelucidated. This study aimed to analyze long-term outcomes of the posterior multilevel crack osteotomy (PMCO) technique for revisional surgery for scoliosis with a fusion mass. Methods: Data from 18 patients who underwent revisional scoliosis surgery using PMCO between 2009 and 2015 and had more than 5-year follow-up were retrospectively reviewed. The Cobb angle and coronal and sagittal balance parameters were examined preoperatively, postoperatively, and during the final follow-up. Perioperative parameters and complications were also assessed. Results: Preoperative and postoperative Cobb angles were 60.5° and 29.9°, respectively (p < 0.001); this improvement was maintained until the final follow-up (33.4°, p = 0.058). The difference in preoperative and postoperative coronal balance was statistically significant (15.9 mm and 9.2 mm, respectively; p < 0.001); this was maintained until the final followup (p = 0.071). There was no change in sagittal balance parameters over the 3 measurement periods. Only 1 patient showed PMCO-related motor weakness, but he spontaneously recovered 3 months after postsurgery. Pseudarthrosis was not observed during the follow-up period. Conclusion: Incomplete osteotomy using PMCO provided satisfactory deformity correction without severe complications during revisional surgery for scoliosis with a fusion mass. It may be a less invasive procedure that maintains cortical continuity, preserves soft tissues, and provides sufficient mobility for the correction of spinal segments.

Background and Objectives Mutations of the SLC26A4 gene cause congenital hearing loss and enlarged vestibular aqueduct (EVA). A considerable proportion of patients with SLC26A4 mutations have significant residual hearing at birth that eventually worsen and become the cause for cochlear implantation (CI) later in their adolescence or adulthood. We analyzed the auditory outcome and prognostic factors of CI in patients with EVA and biallelic SLC26A4 mutations showing progressive early-onset hearing loss, who eventually had implantation in their adolescent or adult periods. Subjects and Method Sixteen patients with EVA carrying biallelic SLC26A4 mutations who received CI after 12 years of age were included for analysis. The outcome and prognostic factors of CI were analyzed. The postoperative follow-up period ranged from 3 to 48 months. Results The age at CI ranged from 12 to 44 years. The categories of auditory performance score was significantly improved after CI from 3.1 to 4.9 (p<0.05). The mean sentence scores improved significantly in the auditory-visual and auditory-only conditions (p<0.05). The significant prognostic factors were measurable bone conduction thresholds, preoperative residual hearing, recent history of sudden aggravation of hearing loss, and preoperative speech intelligibility rating scores. There was a tendency of lower postoperative sentence scores in the group with homozygous H723R mutation, but statistical significance was not reached. Conclusion Despite the early-onset of hearing loss, significant improvement in auditory performance can be expected after CI in adolescent and adult patients with EVA and biallelic SLC26A4 mutations. Significant prognostic factors should be considered in selecting candidates and preoperative counseling for CI. Korean J Otorhinolaryngol-Head Neck Surg 2017;60(12):605-13

A 33-year-old phenotypic female presented with primary amenorrhea. The physical examination revealed no breast development, scanty axillary and pubic hair, normal female external genitalia, and a short blind vagina. The findings of magnetic resonance imaging, karyotyping, and hormonal examinations supported the diagnosis of XY partial gonadal dysgenesis. Laparoscopic surgery showed that spermatic cords, including the bilateral streak gonads and epididymes, were within the inguinal canals. After opening the spermatic cords and identifying the lower borders of the streak gonads, the spermatic cords were transected at the level of the vas deferens. A prophylactic herniorrhaphy using polyprophylene mesh was performed due to weakening of the internal inguinal ring. Pathologic evaluation of the gonads confi rmed the diagnosis of partial gonadal dysgenesis without evidence of malignancy. A laparoscopic approach is feasible for treatment of XY gonadal dysgenesis, even if the streak gonads are present within the inguinal canal.

소아청소년에서의 거골 골연골 병변

송미현(Mi Hyun Song) 대한정형외과학회 2018 대한정형외과학회지 Vol.53 No.3

거골 골연골 병변은 거골의 관절연골과 연골하골에 분절과 분리가 나타나는 질환으로 관절면에서 분절된 골연골편의 안정성과 크기에 따라 예후가 결정된다. 소아 및 청소년에서 발생한 경우 성인의 거골 골연골 병변보다 병변이 치유되고 증상이 호전될 가능성이 높기 때문에 소아청소년에서의 거골 골연골 병변은 초기 치료로 보존적 치료가 우선 시행된다. 하지만 보존적 치료에 실패하거나 병변의 크기가 큰 경우와 전위가 발생한 경우에는 수술적 치료가 권장된다. 수술적 치료가 요하는 경우에는 병변의 상태에 따라 골수자극술, 자가 골연골 이식술 등을 시행하게 된다. Osteochondral lesion of the talus (OLT) is a disease affecting the subchondral bone and articular cartilage of the talus, which may cause fragmentation and displacement of the osteochondral lesion. The stability of the joint and the size of the lesion are important prognostic factors. Conservative treatment is preferred in the initial treatment of OLT in skeletal immature patients because it has a more favorable prognosis than adult OLT in terms of the healing potential and improvement of symptoms. Surgery is recommended when the conservative outcome is unsatisfactory and the fragment is large or displaced. Surgical procedures, including marrow stimulation technique, autologous osteochondral transplantation, and autologous chondrocyte implantation, were performed depending on the condition of the osteochondral lesion.

Background and Objectives:During the last decade, the surgical use of alloplasts has become more and more widespread among otologists. In this study, we evaluated the hearing results of ossiculoplasty using Polycel?? prosthesis. Subjects and Method: One hundred eighty eight cases who underwent ossicular chain reconstruction using Polycel?? prosthesis and had been followed up postoperatively for more than 12 months at Severance Eye-ENT Hospital from 1998 to 2002 were reviewed retrospectively. Postoperative hearing results were assessed by measuring the postoperative air-bone gap (ABG) and closure in air-bone gap. Successful postoperative ABG criteria were defined as the following three groups;ABG of ≤10 dB, ABG of ≤20 dB, and ABG of ≤30 dB. Several prognostic factors such as the condition of middle ear mucosa and ossicles, presence or absence of cholesteatoma, surgical method, staging and revision surgery were analyzed. Results:Of the total of 188 cases, 22 cases (11.7%) were ≤10 dB ABG, 96 (51.1%) cases were ≤20 dB ABG, and 158 (84.0%) cases were ≤30 dB ABG. The hearing results were good for healthy middle ear mucosa and cases which contained stapes superstructure, the hearing results were good. Conclusion:Polycel?? is a good material to be used in ossiculoplasty as a hydroxyapatite and autologous bone. In ossiculoplasty, good prognostic factors of the middle ear condition were healthy middle ear mucosa and the presence of stapes superstructure.

The world on the verge of entering a new milennium, is experiencing a major transition from an industrial society into a "knowledge and informatization based society". The government policy of converting schools into educational institutes equipped with computer networks and programs focuses for the informatization in the field of education as one of the national informatization. In the other hand, school drop-outs are considered as one of big problems at schools. These teenagers tend to commit crimes and become even a social problem Therefore, it is necessary for the Ministry of Education to enforce the application of those to the educational performance for provision of user-centered services. Data mining, which is a new information technology which processes lots of data and derive meaningful information from them, is applied to the case analysis of high school drop-outs for the first time in this paper. That is, a model is created predicting how many students will drop out of high school by using the analysis such as logistic, decision tree, and neural network Also, a foundation is laid being able to counsel students about quitting school, and a concrete case is provided on how the data mining can be used for the informatization in the field of education.

SNS를 활용한 창의성 프로그램 적용가능성 탐색 - ‘창의성 동아리’를 중심으로

김은영,송미현 한국창의력교육학회 2012 창의력교육연구 Vol.12 No.3

The purpose of this study is to examine practicable application and expansion of SNS (Social Networking Service) for creative program through non-curriculum in University. In this study, 22 students in 5 Creativity communitys of S University participate for 5 months. Activities in Creativity communitys were worked with SNS(face-book) and analyzed SNS response, community response, supervisor response, Creative Problem Solving(CPS) response through CPS processes of Treffinger, Isaksen, Dorval(2000). The results of CPS processes in this study were the highest ‘exploring data’ in stage ‘understanding the challenge’ and ‘building acceptance’ in stage ‘preparing for action’. SNS response and community response were higher than all activity in 5 communitys. Also perceived performances of Creativity community were improvement of communication, cooperation, self-confidence, and change of attitude toward life. Practicable applications of SNS in Creativity communitys represented instant communication, data sharing, public relations(PR) etc. This study provided implications about using SNS in CPS processes, applying to creative program through non-curriculum in University. 본 연구의 목적은 SNS를 활용한 대학의 비교과 프로그램 ‘창의성 동아리’를 통해 대학 내 창의성프로그램의 확대와 SNS의 적용가능성을 검토해 보는 것이다. 연구대상은 S여대 창의성 동아리로 5개 팀 22명의 학생이 5개월간 활동하였다. S여대 창의성 동아리 활동은 페이스북으로 진행되었고,Treffinger, Isaken, Dorval(2000)이 개발한 창의적 문제해결 모형 중 과정요소를 활용하여 창의적문제해결반응, SNS반응, 동아리반응, 관리자반응 등으로 동아리 활동을 분석하였다. 연구결과, SNS 를 활용한 창의성 동아리 활동은 창의적 문제해결 과정요소 중 ‘문제(도전)의 이해’ 중 ‘자료탐색’,‘행동(실천)을 위한 준비’ 중 ‘수용적 토대 구축’이 가장 높게 나타났다. 창의적 사고 중에서는 발산적 사고가 수렴적 사고보다 높게 나타났다. 전체 동아리 활동 중에서는 ‘SNS 반응’과 ‘동아리반응’이 높게 나타났다. 그리고 학생들이 지각한 창의성 동아리의 성과로는 의사소통능력 및 협업능력 향상, 자신감 고취, 삶의 태도 변화가 나타났으며, SNS 활용성으로는 즉각적인 의사소통과 자료공유,홍보 등이 나타났다. 본 연구는 대학의 비교과 영역에서 창의성 프로그램의 적용과 SNS를 활용한창의성 프로그램에 대한 시사점을 제공하였다.

A Case of Pseudo-Vestibular Neuritis with Contralesional Canal Paresis due to Spontaneous Bilateral Vertebral Artery Dissection

심대보,송미현,박계천,송창은 대한이비인후과학회 2014 대한이비인후과학회지 두경부외과학 Vol.57 No.8

Pseudo-vestibular neuritis is a central pathology of acute vestibular syndrome, characterized by unidirectional nystagmus mimicking acute peripheral vestibulophaty. We report a 39-year-old female patient who developed cerebellar infarction with isolated vertigo, spontaneous nystagmus, a positive head thrust test, and unilateral canal paresis in the contralesional side. The patient had no vascular risk factors. A diffusion-weighted image of the brain showed infarction of medial branch of posterior inferior and superior cerebellar artery on the left side. A magnetic resonance angiography of neck disclosed a wide range of diffused severe stenosis and narrowing of right and left vertebral arteries, respectively. This case suggests the possibility of vestibular ischemia masking the central pathology in isolated vertigo. Korean J Otorhinolaryngol-Head Neck Surg 2014;57(8):552-5
