상악 골신장술과 하악 상행지시상분할술을 이용한 편측 상하악골 수직 증가술: 증례보고

Maxillary canting and vertical shortening of the unilateral mandibular ramus height is common in cases of severe facial asymmetry. Normally, mandibular distraction osteogenesis (DO) with horizontal osteotomy at the ascending ramus is used for vertical lengthening of the mandibular ramus to correct facial asymmetry with an absolute shortened ascending ramus. In this case report, vertical lengthening of the ascending ramus was performed successfully with unilateral DO and sagittal split ramus osteotomy (SSRO), where the posterior part of the distal segment can be distracted simultaneously in an inferior direction with maxillary DO, resulting in a lengthening of the medial pterygoid muscle. This case describes the acquired unilateral mandibular hypoplasia caused by a condylar fracture at an early age, which resulted in abnormal mandibular development that ultimately caused severe facial trismus. The treatment of this case included two-stage surgery consisting of bimaxillary distraction osteogenesis for gradual lengthening of the unilateral facial height followed by secondary orthognathic surgery to correct the transverse asymmetry. At the one year follow-up after SSRO, the vertical length was maintained without complications.

The latissimus dorsi myocutaneous flap (LDMF) was initially described at the turn of the century by Tansini et al, and latissimus dorsi myocutaneous free flap (LDMFF) was also first described for the coverage of a chronically infected scalp by Maxwell et al. As a pedicled flap, LDMF has been often used for breast reconstruction and for soft tissue replacement near the shoulder and the lower reaches of the head and neck. LDMFF is a flat and broad soft tissue flap with large-caliber thoracodorsal vessels for microvascular anastomosis. A skin paddle of the LDMFF can be more than $20{\times}40$ cm, so very large defects in the oral cavity and outer facial region can be covered by this LDMFF. Other advantages include consistent vascular anatomy, acceptable donor site morbidity and the ability to perform simultaneous flap harvest with tumor resection. For a better understanding of LDMFF as a routine reconstructive procedure in large defects of the oral cavity and facial legion, anatomical findings must be learned and memorized by young doctors during the special curriculum periods for the Korean national board of oral and maxillofacial surgery. This review article discusses the anatomical basis of LDMFF with Korean language.
Styrene과 2-Hydroxypropylacrylate(2-HPA) 공중합 특성
박근호,정영언,김남석,설수덕,서영옥 東亞大學校 大學院 1999 大學院論文集 Vol.24 No.-
Solution copolymerization of Styrene(St.) with 2-Hydroxypropylacrylate(2-HPA) was carried out with Benzoylperoxide(BPO) as an initiator in toluene at 80℃ in a batch reactor. Reaction volume and reaction time were 0.3 liters, 7hours respectively. The time to reach steady state was about the six time. The monomer reactivity ratios, r1(St.) and r2(2HPS) were determined by both the Kelen-Tudos method and the Fineman-Ross method : r1(St.)=0.376(0.330), r2(2-HPA)=0.408(0.778). The activation energy of thermal decomposition was in range of 33∼55 kcal/mol.
입상활성탄에 의한 BTX 및 활로겐화알칸의 기상흡착특성
이행자,정영언,최광재,손진언 東亞大學校 大學院 1993 大學院論文集 Vol.18 No.-
Gas phase adorption characteristics of BTX and halogenated alknaes vapor onto granular activated carbon in the fixed bed were investigated by experimentally. The following results were obtained. 1. For vapor of GAC-BTX and GAC-halogenated alkanes systems, uptake curves were obtained at 298K at various concentration range. 2. Capacity of adsorption of solvents vapors onto granular activated carbon was in the order as follows: ① BTX: m-Xylene> toluene> Benzene> 0-Xylen ②. Halogenated alkanes : CHCl₃>CCl₄>CH₂CL₂ 3. Kangmuir coefficient of each components were shown the TAble 3. 4. RElation of amount adworbated versus surface diffusivity coefficient was obtained like equation D?=a + bq and coefficient a and b were shown the Table 7.
各種 腦疾患에 對한 Technetium 99m Pertechnetate와 Mercury 203-Neohydrin을 使用한 腦走査의 結果
金英鎭,鄭永彦,朱文培,宋鎭彦,徐哲星 최신의학사 1970 最新醫學 Vol.13 No.11
One hundred fifty five patients who had variety of intracranial lesions wers scanned using Chlormerodrin Mercury 203 (35 cases) and Technetium 99m Pertechnetate from January 1967 to July, 1968 at Tae Qu Presbyteian hospital. The results were as follow; 1. Traumatic lesion. We obtained overall accuracy of 80% in localizing epidural hematoma, subdural hematoma, and brain contusion. Technetium 99m' Pertechnetate proved to be somewhat better agent than Mercury 203 Neohydrin. 2. Cerebrovascular lesion. Among 17 patients, only 6 had positive scans (five with ss- Tc and one eith "'Hg.) 3. Infectious disease. Brain scanning may be useful in detection and loclization, of infectious disease as brain abscess, epidural abscess, and tuberculoma. 4. Brain tumor. Meningioma was most accuracy with brain scanning among the brain tumor. Thirty % of astrocytoma with histological between grade I & Il. Was positive signs. 5. Various C. N. S. lesion. Radioactive brain scan was of no value in the diagnosis of various C. N. S. lesions as seizure, amyotropic lateral sclreosis,., headache of various orgin, etc: 6. Hydrocephalus. When 99m Tc was : inserted into the lateral ventricle, we obtained good diagnostic accuracy in patients who was hydrocephalus due to obstruction of aqueduct, aad who was performed ventriculopleural shunting.
