배경 : 흔히 설소대 단축증이 조음장애를 일으키는 원인 중의 하나라고 인식하여 왔으나 설소대 절개술 후에 설소대 단축증 환아들의 조음에 어떠한 변화가 일어나는 지에 대한 연구는 미흡하다. 목적 : 따라서 본원에서는 설소대 절개술이 필요하다고 진단된 아동들에 대한 조음장애의 정도를 알아보고, 설소대 절개술 전 후의 자음정확도를 분석하여 설소대 절개술의 효과에 대해 알아보고자 하였다. (중략)

In the mitral regurgitation (MR) accompanied with a serious ischemic cardiomyopathy (ICMP), coronary revascularization to viable myocardium, LV reduction and mitral reconstruction become the main surgery under the bad conditions that the cardiac transplantation is not so easy. The MR in ischemic cardiomyopathy appears as various pathologic factors, among them, the papillary muscle displacement in addition to the annular dilatation is pointed out as the important cause. Our hospital would like to report the experience of the surgery about coronary revascularization to the left main with 3-vessel coronary disease, severe ICMP patients accompanied with the MR, posterior mitral annuloplasty and papillary muscle plication through the LVtomy.

We treated 654 patients with simultaneous bilateral sympathectomy for essential hyperhidrosis from March 1989 to September 1997(354 males and 300 females). The exposure afforded by thoracoscopy is actually superior to that seen at the time of either thoracotomy or axillary thoracotomy. The use of single-lumen intubation with alternating partially collapsed lung by CO2 inflation resulted in shorter anesthesia, shorter operative time, and shorter hospitalization. 2-mm extended thoracoscopic T2-sympathectomy is not only a time-saving method but also a very simple and effective one in the treatment of hyperhidrosis by experienced surgeons. The modification on our technique of thoracoscopic sympathectomy as described allowed us to significantly improve our previous results. A majority of the patients were relieved, and over 95% were satisfied initially.

우리 군도 신기술 발전 추세에 부응하여 연구개발단계 중에서 탐색개발 단곌ㄹ 통합하여 불요불급한 절차를 단축하고, 핵심기술 연구 확대 및 사전계획성능개량 의무화, 연구개발 기간을 3년 이내로 한정하는 등 체계개발을 위한 제반 여건과 방식을 개선해야 한다. 또한 DFSS의 도입 및 시험평가 제도 개선을 통한 실시간 연구관리체계를 구축하여 사업주관부서의 연구개발 통제력을 강화하고, 연구개발 예산편성 방법을 개선하여 신기술 분야 핵심기술 연구를 활성화시켜야 할 것이다.

Between December 1993 and March 1996, 75 patients had undergone ubannular procedures in mitral valve reconstruction. Their mean age was 45 years and they consisted of 28 males and 47 females. The cause of mitral disease in 75 patients were classified as follow : 29 cases were degenerative, 40 cases were rheumatic, 3 cases were congenital, 2 cases were infectious and 1 case was ischemic. Average number of mitral anatomical lesion per patient was 3.1 and we used average 1.5 procedures on subannular structure in mitral valve per patient. Subannular procedures were chordae shortening 21, chordae transfer 22, new chordae formation 20, papillary muscle splitting 33, shortening of papillary muscle 2. Intraoperative transesophageal echocardiography was carried out for providing an immediate and accurate assessment of the adequacy of the reconstruction. There was no operative death. Patients have been followed up from 2 to 29months, mean 12.5. There were two failures that necessitated reoperation. The mean functional class (NYHA) was 3.19 preoperative and improved to 1.12 postoperatively. After mitral valve repair, the patients were improved hemodynamic, echocardiographic data. In conclusion, subannular procedure in mitral valve repair when feasible is stable and safe with a low prevalence of reoperation.

Purpose: We evaluated the effectiveness of temporary using the extendible external fixator (EF) for lengthening of soft tissue that contracture caused by tumor prosthesis removal in the treatment of complications after limb salvage surgery like deep infection and loosening. Materials and Methods: Five patients six cases were included who underwent extendible EF (Dyna-extor(r)). EF was applied after insertion of half pin to the proximal and distal bone of defect area. EF lengthening started at third day of post-operation, above 2-3 mm per day in the range of no neurological sign. Results: The treatment area was three in femur and two in tibia. Mean age when the time of EF apply was 22.2 years old (range 15-29), but its primary limb salvage operation had done in 13.4 years old (range 9-19), therefore mean times of interval between initial tumor prosthesis reconstruction and temporary EF apply was 8.8 years (range 3-14). One patient had EF for 150 days with 7.2 cm lengthening. Others 5 cases of 4 patients had EF for mean 37 days (range 25-50) and mean soft tissue lengthening was 5.8 cm. Three patients underwent re-insertion of tumor prosthesis and two patients underwent knee fusion as final operation and showed no evidence of infection through mean 22 months follow up period. Conclusion: Temporary using of extendible EF is an effective method for correction of leg shortening which occurred by soft tissue contracture in the complications of limb salvage operation or their treatment process, and it could be provide easily application of tumor prosthesis and knee fusion as final operation.
