Purpose: The transverse rectus abdominis myocutaneous(TRAM) flap has become a mainstay of breast reconstruction. The chief disadvantage of the TRAM flap is its potential to create a weakness in the abdominal wall. Nowadays true hernia is less frequent, but bulging that appears at the muscle donor site, or at the contralateral side, or at the epigastric area is still remained as a problem. To prevent this complications, we have used synthetic mesh as well as abdominal muscle plication. Now we report the result of our methods. Methods: We started to use synthetic mesh and muscle plication as supplementary reinforcement for entire abdominal wall, after TRAM flap harvesting, in an attempt to stabilize it and achieve a superior aesthetic result since 2002. We observed complications of TRAM flap donor site, and compared our results (from January, 2002 to January, 2006) with other operator's result (before 2001) at the same hospital in aspect of incidence of abdominal complications. Results: 42 consecutive patients have been performed routine reinforcement with the extended mesh technique and muscle plication from January, 2002 to January, 2006. Mean patient follow up was 25.2 months. No hernia or mesh related infection were encountered and only one patient had a mild abdominal bulging. Nevertheless the our good results, there were no significant statistical differences were observed between two groups. Conclusion: We recommend the using of synthetic mesh and muscle plication for donor site reconstruction after TRAM flap breast reconstruction to improve strength as well as aesthetic quality of the abdominal wall.

Purpose: Generally speaking, most of Korean have smaller eyes than those of Caucasian and they have epicanthus with narrow palpebral fissure. It makes external appearance looking dull because the length of the palpebral fissure is short and there is a epicanthus. In case the function of the levator muscle is weak, their eyes look much smaller. Epicanthus and weak levator muscle function make the eyes look dull. The above mentioned, authors want to introduce double eyelid operation, epicanthoplasty, levator plication to extend and lengthen the palpebral fissure. Methods: From August 2001 to August 2004, there were 138 cases that had double eyelid operation with epicanthoplasty or levator plication. the 69 cases of them had double eyelid operation and epicanthoplasty, the 33 cases of them had double eyelid operation and levator plication and the 36 cases of them had double eyelid operation and epicanthoplasty and levator plication. Results: After the operation, the length and height of the eyelid are improved remarkably, and most of the patients were satisfied. The length of the eyelid is improved 3 to 5mm($3.4{\pm}0.5mm$) in case of the epicanthoplasty, the width of the eyelid is improved 3 to 4mm($3.1{\pm}0.3mm$) by the levator plication. The length of the eyelid is improved 3 to 5($3.4{\pm}0.4mm$) and the width is improved 2 to 4mm($2.9{\pm}0.5mm$) by the epicanthoplasty used levator plication. Conclusion: The improvement of the eyelid length is almost the same as epicanthoplasty and levator plication are done simultaneously. But the improvement of the eyelid width is less shorter when epicanthoplasty and levator plication are done simultaneously than the case of levator plication alone. This is because there is a tension influencing on the limitation of widening palpebral fissure to fix the epicanthal tendon. This method is recommendable for the patients who want to have much bigger eyes.

Background: Surgical correction needs to be considered when diaphragm eventration leads to impaired ventilation and respiratory muscle fatigue. Plication to sufficiently tense the diaphragm by VATS is not as easy to achieve as plication by open surgery. We used pneumatic compression with carbon dioxide ($CO_2$) gas in thoracoscopic diaphragmatic plication and evaluated feasibility and efficacy. Methods: Eleven patients underwent thoracoscopic diaphragmatic plication between January 2008 and December 2013 in Pusan National University Hospital. Medical records were retrospectively reviewed, and compared between the group using $CO_2$ gas and group without using $CO_2$ gas, for operative time, plication technique, duration of hospital stay, postoperative chest tube drainage, pulmonary spirometry, dyspnea score pre- and postoperation, and postoperative recurrence. Results: The improvement of forced expiratory volume at 1 second in the group using $CO_2$ gas and the group not using $CO_2$ gas was $22.46{\pm}11.27$ and $21.08{\pm}5.39$ (p=0.84). The improvement of forced vital capacity 3 months after surgery was $16.74{\pm}10.18$ (with $CO_2$) and $15.6{\pm}0.89$ (without $CO_2$) (p=0.03). During follow-up ($17{\pm}17$ months), there was no dehiscence in plication site and relapse. No complications or hospital mortalities occurred. Conclusion: Thoracoscopic plication under single lung ventilation using $CO_2$ insufflation could be an effective, safe option to flatten the diaphragm.

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.

Congenital diaphragmatic eventration is a rare disease and generally accepted as an abnormally high position of part or all of the diaphragm, usually associated with a marked decrease in muscle fibers and a membranous appearance of the abnormal area. There were 4 cases of the congenital diaphragmatic eventration at the Dept. of Thoracic Surgery, Seoul National University Hospital, from 1957 to 1977. They were two boys and two girls and ranging from 1 day to 3 years of age. They were all repaired by surgical operation and one was expired postoperatively, another one was dead one year later due to complication. The ratio between right and left was 1:3 and their symptoms were cyanosis, dyspnea and frequent respiratory disease. In physical examination there was noted decreased breathing sound on the affected lung field and bowel sound was audible in some cases. Diagnosis was done by Chest X-ray and plication of the affected diaphragm was usually done in operation. There were noted atelectasis and cystic change of the affected side lung. And the liver, colon, spleen and small intestine were found in the dome of the eventrated diaphragm.

Eventration of the diaphragm is, by definition, abnormally high or elevated position of diaphragm as a result of paralysis, aplasia or atrophy of varing degrees of muscle fibers, and the cause of which may be congenital or acquired. The unbroken continuity of the diaphragm differentiates it from diaphragmatic hernia. The clinical manifestations of the condition, if present, are usually due to the interference of the ventilatory function of the lung and digesive dysfunction due to gastrointestinal distorsion. Treatment consists of surgical repair of the relaxed diaphragm to it`s normal position. A ease of left sided eventuration of the diaphragm, 31 year old officer, was found by chance after traffic accident with chief complaints of hemoptysis and multiple superficial contusions. Routine chest roentgenogram and barium study of the colon revealed moderately elevated left hemidiaphragm with displacement of the splenic flexure of the colon into the left chest. Past history revealed frequent attack of upper respiratory infection and some abnormal condition on his left chest announced by screen cheek of chest X-ray at the time of entrance for his army service 3 years before. Plication of the relaxed diaphragm through left thoracotomy was done and result was excellent as seen on Fig. 5. Cause of eventration of the left hemidiaphragm was due to paralysis of the left phrenic nerve which was tested during thoracotomy.

Purpose: We have classified blepharoptosis into the categories including pseudoptosis in Koreans and compared with other previous studies. Methods: Total of 250 patients(398 eyes) who underwent surgery for blepharoptosis from 1987 to 2006 were studied. By classification of Beard, patients were categorized into congenital, acquired and pseudo blepharoptosis and later they were reclassified by their etiologies. Also addition of pseudoptosis to the classification of Frueh, blepharoptosis were categorized into neurogenic type, myogenic type, aponeurotic type, mechanical type and pseudoptosis. And we divided these cases by the degree of blepharoptosis, levator function and the operation methods. Results: Out of the 250 patients, 175 patients were congenital type, 49 were acquired type and 26 were pseudoptosis. According to the mechanistic classification, 177 myogenic type, 30 aponeurotic, 7 mechanic, 8 neurogenic and 28 pseudoptosis were categorized. Regarding severity of blepharoptosis, there were 29.2% of mild, 40% of moderate, and 30.8% of severe cases. Out of the 398 cases, in terms of the operation methods, there were 39 aponeurosis plication, 184 levator resection, 5 Muller tucking, 60 Orbicularis oculi muscle flap, 66 frontalis transfer, and 21 blepharoplasty. Conclusion: The cause and degree of ptosis, and levator function are very important when considering the amount of resected muscle. There were only a few studies about blepharoptosis classification including pseudoptosis category. Therefore, through this study, we can investigate the relationship between the pseudoptosis and the others. This study could be useful for the making future management plans of blepharoptosis in Korean patients.

승모판 재건술의 장점은 이미 잘 확립되어져 왔고 그래서 최근에는 승모판막 질환에서 판막 재건술 이 선택적인 수술수기로 여겨지고 있다. 저자들은, 승모판막 폐쇄부전으로 판막 재건술을 시행한 38례(승모판 재건술을 시행받은 환자는 총 49명이었으나, 승모판막 치환술을 받은 11명의 환자는 제외함.)의 환자들에서 중기성적을 보고하는 바이다. 대상 및 방법: 1991년 3월부터 2001년 3월까지, 38명의 환자가 승모판막 폐쇄부전으로 판막 재건술을 시행받았고, 일부는 판막협착이 동반되기도 하였다. 평균연령은 47.6 $\pm$ 14.7세(범위 15~70세)이고 이중 11명은 남자 27명은 여자였다. 폐쇄부전의 원인은 퇴행성 14, 류마티스성 21, 감염성 2, 선천성 1명이었다. 결과: Carpentier 기능분류상 제일형 3례, 제이형 16례이고 제삼형은 19례 이었다 적용된 수술수기는 판륜성형술 15, 교련절개술 19, 판첨절제 및 판륜중첩술 9, 건삭단축술 11, 건삭 전이술 5, 새로운 건삭형성술 2례이고, 유두근분할이 2례, 판첨의 세균성증식 제거술이 2례 이었고, 이들 수기들은 대부분 환자에서 복합적으로 적용되었다. 조기사망이 2명이었는데 사망원인은 호흡부전, 신부전 그리고 폐혈증이었고, 만기사망은 없었다 또한 중등도의 승모판막 폐쇄부전 및 승모판의 협착으로 총 6례에서 판막재건술 후 승모판막 치환술이 이루어졌다. 추적관찰 기간은 1개월부터 116개월이고 평균 43개월이었다. 수술 전 후 NYHA 기능분류는 술 전 2.36에서 술 후 1.70으로 호전된 양상을 보였다. 결론 : 대부분의 승모판막 폐쇄부전에서 기술적으로 환자에게 적용이 가능하다면 판막 재건술은 안정적인 기능적 결과를 얻을 수 있고 또 낮은 수술사망이나 만기사망을 얻을 수 있는 효과적인 수술수기가 될 것이다.맥 차단 시간은 평균 $96.6{\pm}35.3$분 이었고, 심폐관류 시간은 평균 179.2${\pm}$94.6분이었다. 전체 조기 사망률은 8.6%이었으나 선택적 수술에서의 사망률은 3.1%였으며 가장 흔한 사망 원인은 6례(2.1%)에서 나타난 저심박출증이었다. 조기 사망에 영향을 미치는 요소는 고혈압, 70세 이상의 고령, 좌심실 박출계수 40% 미만의 좌심실기능 저하, 울혈성 심부전, 술전 대동맥내 풍선펌프, 응급 수술, 만성 신부전이었다. 생존한 환자 269례중 241례에서 추적관찰을 시행하였으며 평균 추적관찰 기간은 39.0127.0개월이었다. 만기 사망이 7례(2.9%)에서 있었으며 이중 4례가 심장질환으로 인한 사망이었고, 증상의 재발이 14례(5.8%)에서 발생하였다. 증상이 재발한 환자 14례중 13례에서 관상동맥 조영술을 시행하였으며 이에 준하여 재관상동맥 우회술, 관상동맥 중재술과 약물요법을 시행했고 1례를 제외한 12례에서 이후 증상의 재발은 없었다. 결론: 관상동맥 우회술후 조기 성적뿐 아니라 만기 사망과 증상의 재발 등에 관하여 지속적으로 추적관찰을 하여 비교적 만족할만한 성적을 얻었으나 성적을 향상시키기 위해서는 수술수기의 향상뿐 아니라 수술후 관리와 외래 추적관찰 등에 대한 적극적인 관심도 필요할 것으로 생각된다.하고도 완전교정술 도달 확률이 높은 치료전략이라는 사실을 입증하였으며 주대동맥폐동맥혈관부행지의 크기나 숫자가 단일화하기 쉬운 형태학적 특징을 지닌 경우에는 조기에 일단계완전교정술을 시행하여 양호한 결과를 얻을 수 있다는 사실을 발견하였다. 반면 본 환아군 중 단일화술을 먼저 시도한 군에서는 비록 단계적인 단일화를 시도한 군에서 단일화술과 관계된 수술사망율이 약간 낮기는 하였으나 완전교정술까지 완료될 가능성에는 차이가 없었다. 그러나
