From Jan 1982 through Dec.1991, thirty-three DeVega`s tricuspid annuloplasties were performed in association with mitral and combined mitral and aortic valve disease. Preoperatively,all of the patients were in NYHA functional class III or IV.There were one early death and 4 patients died during follow up period of 18 to 138 months [ mean follow up : 67.3 months ]. Nine patients required reoperation because of biological mitral valve failure at 4.7 to 11 years after tricuspid annuloplasty[TAP]. Among these patients,2 cases needed for reoperation of TAP due to loosening of suture material. Twenty four [86%] of the survivors were in NYHA functional class I or II after TAP.The actuarial survival rate for the TAP was 74% at 138 months. Rt atrial pressure of 9 reoperation cases were significantly decreased [P<0.05] compared with initial Rt.atrial pressure [ Mean period; 93.6 months].Doppler echocardiographic studies for tricuspid regurgitation were performed in 15 cases after TAP [Mean period: 42.3 months].These results showed significantly reduced [P<0.01] tricuspid annulus diameter and tricuspid regurgitation distance [ P<0.05 ].Our surgical experience that the DeVega`s TAP is a simple,safe,effective procedure and resulted in good hemodynamic improvement with moderate to severe functional tricuspid regurgitation.

A 3-year-old castrated male Siberian husky was presented for evaluation after being hit by a car. On physical examination, the dog showed open-mouth, displacement of mandible and hypersalivation with blood ting. The base of tongue was transected almost 80% on the bias from right dorsal side to the left ventral side. Radiography demonstrated separation of mandible symphysis, and fracture of right condyle and vertical ramus. After debridement of the necrotic tissue, tongue apposition with simple interrupted suture was performed. Mandibular symphysis, condyle and mandibular vertical ramus fractures were fixed using pin, cerclage wire, T-plate, and K-wires. The mouth was irrigated daily using chlorhexidine after surgery. The sutures that were loose here or untied at tongue were re-sutured under sedation. The transected tongue was healed and recovered its normal movement after 6 weeks.

Previously reported nipple-areolar complex reconstruction (NAR) methods involve multiple incisions and wide skin redraping, which increase retraction forces and heighten the risk of nipple-areolar complex (NAC) flattening. We introduce a NAR method using the long V-Y advancement technique that can overcome these disadvantages. A V-shaped flap is designed with the width of the flap base 4-5 mm larger than the diameter of the normal nipple. The flap length is designed to be at least 2.5 times its width. Dissection is performed to the top of the artificial dermal matrix or muscle layer. The nipple is constructed with the same projection as the contralateral side by folding the elevated flap. The tip of the elevated flap is apposed in the middle of the donor defect to minimize the deformity during donor site closure. A 3-point skin suture is applied to the upper third of the folded flap to mold its shape. Using this long V-Y advancement technique, we successfully decreased skin tension in NAC flaps and improved the maintenance of reconstructed nipple projection. The long V-Y advancement technique provides an easy, simple NAR method, effectively maintaining longer nipple projections and reducing breast deformities, especially in Asian women with relatively large nipples.

The motality rate of acute subdural hematoma(ASDH) associated with closed head injury is high in spite of recent advances in neurosurgery. Many variables in regard to outcome of ASDH have been assessed. But among them, intracranial pressure(ICP) control and the time interval between injury and operative evacuation are the only things that can be affected by doctor. We introduced a simple method to the management of ASDH for reducing the time interval between injury and operation. When the immediate decompressive operation of ASDH was impossible by any causes, we made a burr hole at the center of hematoma, usually on 2-3cm above temporal squama and 1-2cm behind coronal suture under local anesthesia before main operation. Partial hematoma evacuation was achieved through the burr hole and it was effective in preventing further worsening of patients neurological status before main operation. Prompt hematoma evacuation through the burr hole seemed to be effective in delaying secondary ischemic brain damage and made easy to closing the dura opening and replacement of the bone flap at the end of main decompressive operation. This easy method may reduce the time interval between injury and operation. We represent surgical technique with two cases of ASDH managed with this simple method.

Background Although the conventional direct brow lift operation provides a simple means of managing lateral brow ptosis, the scars produced have been unacceptable. However, using the modifications proposed here, scarring showed remarkable improvement. This article reviews our experiences with the presented technique, mainly with respect to postoperative scarring. Methods Measured amounts of supra-eyebrow skin and subcutaneous fat were excised en bloc in the conventional manner under 'hyper-hydrated' local infiltration anesthesia. The lower flap and the edge of the upper flap were undermined above the muscular plane, and the orbicularis oculi muscle was directly suture-plicated and suspended upward to the distal frontalis muscle. Skin closure was performed in a basic plastic surgical manner. Results From April 2007 to April 2012, a consecutive series of 60 patients underwent surgery using the above method. The average width of the excised skin was 8 mm (range, 5-15 mm) at the apex of the eyebrow. Preoperative complaints were resolved without occurrence of significant complications. The surgical scars showed remarkable improvement and were negligible in the majority of the cases. Conclusions The direct brow lift operation combined with plication/suspension of the superior and lateral portion of the orbicularis oculi muscle provides a simple, safe, and predictable means of correcting lateral brow ptosis. The scars were acceptable to all of the patients. For proper management of the frontalis tone, upper blepharoplasty and/or repair of eyelid levator function must be considered in addition to brow lift procedures.

고령사회의 진입과 더불어 인간의 평균 수명이 연장됨에 따라 현대 사회의 남성 및 여성의 외모에 대한 관심이 증가하는 추세이다. 사람의 노화를 가장 외면적으로 판단할 수 있는 것이 바로 얼굴의 피부 주름이다. 깨끗하고 주름이 없으면서 탄력성 있는 건강한 피부를 갖기 위하여 사람들은 각종 시술을 받고 있다. 시술 중 간단하면서도 효과적인 시술을 원하는 경향이 있어 실리프팅 시술 방법이 많이 시행되고 있다. 본 연구에서는 실 리프팅 시 리프팅 효과를 개선시키기 위하여 기존의 PDO봉합사 시술에 RF고주파와 CO₂ gas를 주입하여 주름의 개선을 확인하기 위한 동물 실험을 진행하였다. 시술 전과 후의 주름 개선의 비교는 Labview를 이용한 주름 평가 프로그램으로 진행하였으며, 동물실험의 데이터는 시술 후 10주차 측정 데이터를 사용하였다. 실험그룹은 자연노화 그룹, PDO 시술 그룹, PDO에 RF고주파를 주입한 그룹, PDO에 CO₂ gas를 주입한 그룹, PDO에 CO₂ gas와 RF를 동시에 주입한 그룹으로 진행하였다. 자연노화 그룹의 개체들은 시술 전 평균 주름의 깊이는 0.408mm이었고, 10주째의 평균 주름의 깊이는 0.68mm으로 자연노화가 진행되었다. PDO 시술 그룹의 개체의 주름의 깊이는 시술 전 평균 0.384mm이었고, 시술 후 10주째에는 평균 0.348mm이었다. PDO에 RF고주파를 주입한 개체의 시술 전 평균 주름의 깊이는 0.42mm이었으며, 10주째 평균 주름의 깊이는 0.378mm이었다. PDO에 CO₂ gas를 주입한 개체는 시술 전 평균 주름의 깊이는 0.4mm이었으며, 시술 후 10주째 평균 주름의 깊이는 0.332mm로 감소하였다. PDO에 CO₂ gas와 RF고주파를 주입한 개체는 시술 전 평균 0.412mm, 시술 후 10주차 0.338mm로 감소를 볼 수 있었다. 동물 실험을 통하여 PDO봉합사에 CO₂ gas와 RF를 주입한 시술이 가장 높은 17.96%의 감소율을 보였다.

With the ligation of a patent ductus arteriosus by Gross in 1938, surgeons first entered the field of congenital heart disease, and treatment of the patent ductus is representative of the rapid advance made in thoracic surgery in the last 40 years. We have had clinical experiences about 36 cases of this in the department of Thoracic & Cardiovascular surgery, Pusan Paik Hospital, Inje medical college from March 1891 to June 1987. And the results were summarized as follows. 1. There were 11 males, 25 females. The age range of the patients were from 8 months to 36 years with the mean age of 7.9 years. 2. The chief complaints of the patients on admission were frequent URI[50%], dyspnea on exertion[29.8%], chest pain[11.1% k 1%], growth retardation[2%], cough[2.8%], anorexia[2.8%]. But there were 11 patients[30.6%] having no subjective symptoms. 3. In auscultation, the usual continuous machinery murmur was noticed in 30 patients[83.3%], only systolic murmur in 6[16.7%]. 4. In the preoperative chest P-A views, there were noticed cardiomegaly in 20 cases, enlarged pulmonary conus and / or pulmonary plethora in 22 patients[61.1%]. 5. In the preoperative EGG findings, there were noticed pattern of LVH in 8 patients[22.2`], RVH in 2[5.6%], BVH in 4[11.5%] and normal in 19[52.89o]. 6. The size of PDA[mean] was 9.5 mm[length] and 8.8 mm[width], the range of length was from 4 to 29 mm and the range of width was from 4 to 18 mm. 7. There were noticed 6 cases which were combined with other anomalies[VSD in 2 cases, Coarctation of aorta in 2, Mitral regurgitation in 1, and AP window in 1]. 8. On operation, simple ligation of the ductus was performed in 30 cases[83.3%], division and suture-ligation in 5[13.9%]. 9. Postoperative complications were noticed in 4 cases[pneumonia in one case, wound infection or disruption in 3], but there were no mortality.
