구강은 다양한 기능을 가지고 있다. 즉, 소화, 호흡 및 발음의 기능을 주로 하며, 심미적으로 매우 중요하다. 그러므로 토진 및 구개열과 같은 기형은 위에 열거한 작용을 훼손시켜, 환자 본인은 물론, 주위 사람들에게 커다란 불행이라 할 수 있다. 그리하여 토진 및 구개파열을 수정하려는 노력은 고대로부터 출발된다. Boo-Chai는 A.D390년경에 중국에서 토진수술이 있었다고 1966년에 보고한 바 있다. 이후에는 수많은 사람들이 토진 및 구개파열에 대한 수술방법을 제시하여 왔으며 현재에도 여러 가지 다양한 수술방법이 이용되고 있다. 그러므로 토진 및 구개파열을 전반적으로 다루는 것은 매우 방대한 것이기 때문에, 먼저 발생빈도, 원인 및 분류에 대하여 간단히 이야기하고 수술시기와 장 많이 쓰이고 있는 수술방법을 다루기로 한다.

Mitral valve surgery is most commonly performed through the left atriotomy via the inter-atrial groove or trans-septal approach. An alternative method for approaching to the mitral valve is via the dome of the left atrium located between the ascending aorta and superior vena cava. Although this approach was described 30 years ago, it has not been popularized in mitral valve surgery. We introduce our recent experiences with mitral valve surgery carried out through the dome of the left atrium with brief review of literature.

배경: Maze수술은 승모판 질환에 동반되는 심방세동의 효과적인 치료방법으로 알려져있다. 이 연구는 승모판 수술과 심방세동 수술을 동시에 시행한 환자에서 심방세동 수술 후 중기적인 결과와 그 재발 여부를 조사하였다. 대상 및 방법: 심방세동 수술과 승모판 수술을 받은 11예의 환자(10예는 류마티스성 승모판 질환)를 대상으로 하였다. Maze II 수술 및 그 변형수술을 6예에서 시행했고, Maze III 수술 및 그 변형수술을 5예에서 시행하였다. 심방세동 수술 후 좌심방의 수축정도를 심방세동 수술 없이 승모판 수술만으로 동율동을 얻은 경우와 비교하였다. 결과: Maze II 수술을 받은 환자 6예 중 5예(83.3%)에서, maze III 수술을 받은 환자 5예 모두에서 동율동을 회복하였다(전체적으로 90.9%). 전자의 1예(20%)와 후자의 2예(40%)에서 수술 후 각각 23, 2, 13개월만에 심방세동이 재발하였다. 그 후 다시 2예는 동율동으로 전환되었으나, 1예는 재발된 심방세동을 그대로 유지하고 있다. 변형술을 받은 3예에서는 심방세동의 재발이 없었다. Maze 수술 후 4예(40%)에서만 좌심방의 수축기능을 보였으며, maze 수술 후 좌심방 수축 정도(승모판의 A파의 속도)도 maze 수술 없이 승모판 수술과 항부정맥제 투여로 동율동을 회복한 경우보다 낮았다. 결론: 심방세동을 동반한 승모판 수술 환자에서 maze 수술로써 심방세동으로부터 동율동을 회복할 수 있으나 중기적으로 재발할 수 있으며, maze 수술 후 좌심방 수축정도는 상당히 떨어질 수 있다고 생각된다.

뇌하수체 종양에 대한 경비중격 경접형동 수술은 1907년 Schloffer가 비절개수술에 의한 방법을 보고한 이래 1914년 Cushing이 sublabial approach를 정립하였으나, 이후 약 반세기 동안 경비중격 경접형동 수술이 개두술에 비해 종양의 재발율이 높다는 이유로 기피되어왔다. 1968년에 이르러 Cottle의 maxilla-premaxilla approach로 비중격에 대한 수기가 축적되고 수술현미경의 발달로 미세수술이 도입되면서 경비중격 경접형동수술이 다시 각광을 받게 되었다. 이후 sublabial approach, alotomy approach, columellar approach, external rhinoplasty approach 등이 개발되어 보고되었으며 접형동의 함기화가 불완전한conchal 형이나 터어키안 상측부로의 종양의 확장이 심한 예를 제외하고는 모두 이 방법으로 수술을 시행하는 것이 보편화되어 있으며 문헌고찰에 의하면 개두술시의 술후 사망율이 17%인데 비해 경비중격 경접형동술의 경우 1.8%라고 보고되고 있다. 서울대학교병원 이비인후과에서는 sublabial approach로 터어키안까지 종양을 노출시킨 후 신경외과의와 공동으로 뇌하수체 종양을 치료한 예를1977년부터 1988년까지 135례를 보고한 바 있다. 최근에는 sublabial approach의 단점을 보완하면서 외비의 해부학적인 구조에 익숙해질 수 있는external rhinoplasty approach를 이용하여 경비중격 경접형동 수술을 시행하고 있으며 1977년부터의 치험례를 임상분석하여 특히 external rhinoplasty approach의 수술성적을 보고하는 바이다.

Although variable surgical methods of sympathetic nerve for palmar hyperhidrosis are curative and safe therapeutic options, they have some limitations such as compensatory sweating and anhidrosis of hand in long term satisfaction rate. Material and Method: Therefore, we tried to decrease severity of compensatory sweating and prevent excessive dryness of hand through selective division of rami communicantes of thoracic sympathetic ganglia distributed to the hands(ramicotomy). Result: In postoperative results, about half of the patients maintained humidity of hands and most of them showed no more than mild degree of compensatory sweating. Conclusion: Therefore, ramicotomy of thoracic sympathetic ganglia can be recommended as selective and physiologic surgical method for palmar hyperhidrosis.

Recently the cases of varicose veins are increasing because the patients with latent disease have come to realize that they want a positive treatment. Accordingly, the purpose of this study is to compare and analyze two methods the conventional phlebectomy (CP) and transiliuminated powered phlebectomy (TIPP). Material and Method: From March 200f to December 2004, 114 patients (167 legs) with varicose vein were operated in Pusan National University Hospital. A retrospective review was performed on the clinical records. We analyzed age, sex, duration of illness, chief complaints, duplex doppler findings, number of skin incisions, operative time, length of hospitalization, complications, and remnant lesions. Result: Operative time was significantly shorter in the TIPP group than CP group (for one leg $108.4\pm27.6\;min\;vs\;83_4\pm24.4\;min,\;for\;both\;legs\;184.7\pm28.4\;min\;vs\; 137.8\pm24.4\;min)$. There was signifcant statistical difference in average number of skin incisions per leg between the CP group and the TIPP group $(5.9\pm2.2\;vs\;4.2\pm1.6)$. Mean duration of hospitalization was Significantly shorter in the TIPP group than CP group $(4.4\pm1.0\;days\;vs\;5.8\pm1.9\;days)$. Complications were pain $(15.9\%)$, remnant lesion $(9.5\%)$, and ecchymosis $(4.8\%)$ in the CP group and ecchymosis $(19.6\%),\;pain\;(7.8\%),\;and\;remnant\;lesion\;(7.8\%)$ in TIPP group. Sclerotherapy or reopertaion was done for the patients who had remnant lesions. Conclusion: Transilluminated powered phlebectomy in varicose vein could reduce operative time and number of skin incisions, and almost completely removed the multiple lesions. Although there were postoperative complications such as ecclymosis, they were absorbed within 2 months and patients were satisfied. Therefore, TIPP is a more effective operative technique than conventional phlebectomy in varicose veins.

Perimembranous ventri ular septal defects(PMVSDS) are the most common type of ventricular septal defects(VSDs) and consist morphologically of deficiency of the membranous septum and variable portions of the adjacent muscular septum. Repair of VSD has begun via a right ventriculotomy. Even with this exposure, however, it mght lead to ventricular dysfunction. Transatrial exposure of VSDs is luiown to a versatile approach to PMVSDS and even malaligunent defects can be repaired by this method. Although transatrial exposure can be improved by taking down'the atrioventricular valve at the annulus, surgeons have been hesitant to do so because of concern for valvular competence. Therefore, this study was undertaken to clarity the effects of transamlular approach of tricuspid valve (TATV) at operation of PMVSD. During last 5 years, twenty eight cases from 96 patients of PMVSD were closed by TATV and follow up study was done from 3 months to 33 months and results were obtained as follows. 1. Age at operation was fr m 4 months to 38 years and most patients(17, 62%) were above 5 years. 2. Preoperative pulmonary-systemic flow ratio(QPIQS) was ranged from 1 to 2.8 and 22 patients(79%) were less than 2. 3. Peak systolic pulmonary artery pressure was below 30mmHg in 8, 30-50mmHg in 17, above 50mmHg in 3 patients and 25 patients(89%) were less than 50mmHg. 4. Preoperative tricuspid regurgitation(TR) is none in 12, trivial in 6, mild in 3, moderate in 5, severe in 2 patients but postoperative TR was none in 18, trivial in 6, mild in 4 patients, so TR in most patients had decreased or not. 5. Indications for operation were based on the presence of a significant shunt. However, in patients with small shunts, indications for operation were included additional factors, tricuspid valve pouch, RVOT obstruction(right ventricular outflow tract obstruction), subacute bacterial endocarditis and associated anomalies. 6. There were no hospital deaths and residual shunts in postoperative echocardiography. Therefore TATV is especially a good method in PMVSn where patients have trcuspid valve pouch. And it is a safe and effective technique that improves exposure for PMVSD repair and does not adversely affect tricuspid valvular competence.

Background: Early detection and surgical resection offer the most advantage out of all cures for lung cancer. Elderly patients may fail to benefit maximally from these interventions because of their general condition and residual lung function. To study the impact of age on stages, histology, symptoms, and treatments of the patients with non-small cell lung cancer, we undertook a retrospective review. Material and Method : Two hundred eleven patients with non-small cell lung cancer were operated on at Samsung Seoul hospital between October 1994 and June 1997. Patients were arbitrarily arbitrarily by age less than 70 years(176 patients) and 70 years or more(35 patients), and their medical records were reviewed. Result: There were no differences in pathologic staging and diagnosis. But there were differences in surgical methods, complications, and mortality rates between the two groups. There were much more complications in the 70 years or more group(p=0.02). We chose less invasive surgical methods in the 70 years or more group. Conclusion: More complications were experienced in the 70 years or more group. Although thoracic operation imparts the greatest survival advantage, this benefit is diminished in elderly patients because of their high complications and mortality rate. We recommend serious consideration of surgical indications and operative methods.
