외과적 치주처치의 근본 목적은 치주낭을 제거함으로써 질환의 진행을 정지시키고 치주조직을 건강한 상태로 회복시켜 주는데 있다. 임상에서 적용할 수 있는 외과적 처치술식은 치주낭의 깊이, 부착치은의 폭경, 치조골의 상태, 염증의 진행정도 등의 사항을 고려하여 선택되어져야 하며, 대표적인 술식으로는 치은 절제술(gingivectomy), 치은 판막술(modified Widman flap, open flap curettage)등을 들 수 있다. 치은 절제술은 치은조직을 제거해야 한다는 의미에서 볼 때 부착치은의 넓이와 골내낭의 유무를 판단하여야 하며 치은판막술은 깊은 치주낭을 성성하고 있거나 골내낭이 있거나 부가적인 치조골의 처치가 필요한 경우 시행될 수 있다. 그러나 외과적 치주처치의 어떤 방법을 택하던지간에 계속적인 치태관리가 더 중요한 요인으로 강조되어야 한다.

가축의 일란성 쌍태를 생산하기 위한 기술 개발을 확립하고자 상실배 및 포배기에 있는 BALB/c 계통의 생쥐 수정란을 micromanipulator로 분할 수정란을 작출하고 이를 체외배양을 실시하여 발달성적을 조사하였으며, 외과적 및 비외과적 이식을 실시하여 착상율 및 산자생산 성적을 조사한 결과는 다음과 같다. 1. 상실배 및 포기배에 있는 총 811개의 정상적인 수정란을 분할하여 이중에서 666(82.1%)개가 분할시의 물리적인 손상이 없이 분할되었고, 이때 분할 성공율은 발달단계 간에 유의적(P<0.05)인 차이가 없었다. 2. 분할 수정란중 상실배는 30-36시간, 초기 배반포 및 확장 배반포는 3-6시간 배양을 실시한 결과 분할 수정란중 한쌍이 모두 정상적으로 배양된 것은 각각 70.0%, 80.4% 및 73.1%로써 이들 발달단계 간에 유의적(P<0.05)인 차이가 없었다. 3. 분할된 상실배와 정상적인 수정란의 이식후 수태율은 각각 63.6% 및 61.3%로써 유의적(P<0.05)인 차이가 없었다. 그러나 분할된 상실배에 있어서 배양을 하지 않고 이식한 경우에는 전혀 수태되지 않았다(P<0.05). 4. 분할된 포배기 수정란을 체외 배양후 이식한 수태율(55.5%)과 배양과정을 거치지 않고 이식한 성적(43.8%) 그리고 정상적인 포배기 수정란을 이식한 수태율(55.4%) 간에는 유의적(P<0.05)인 차이가 없었다. 5. 분할 수정란을 외과적 방법으로 이식한 경우는 52.8%의 수태율을 얻었으나, 비외과적 방법으로 이식한 경우 27.5%로써 외과적 방법으로 이식한 경우보다 수태율이 유의적(P<0.05)으로 낮았다.

Traumatic intrusive luxation, an occurrence common in the primary dentition but one that occurs rarely in the permanent dentition, has a poor prognosis. There have been many treatment approaches such as allowing the tooth to reerupt spontaneously, surgical repositioning and immediate luxation, surgical luxation, and orthodontic repositioning; but all have their own drawbacks. Meanwhile, Turley et al. (1987) have proposed surgical and orthodontic combination therapy to treat intrusion. Surgical and orthodontic combination therapy means to apply the orthodontic traction force immediately after surgical luxation. If ankylosis occurs, orthodontic force may be applied after re-luxation repeatedly. But in cases of complete intrusive luxation, it would be not feasible to bond an orthodontic button or bracket on the tooth directly. Thus, in this case, traction of the tooth was attempted after surgically repositioning it close to the probable original socket site to promote better healing.

Impacted teeth occur at higher frequencies in permanent than primary dentition. The most frequently affected teeth are the maxillary and mandibular third molars, whereas it is quite uncommon for the mandibular first molar to be impacted. Treatment methods for impacted teeth include continuous examination for independent eruption, surgical exposure, subluxation after surgical exposure, orthodontic traction, and surgical repositioning. If all of these treatments fail, tooth extraction may be considered. In the first case study, an 8-year-old boy was treated with surgical exposure, after which he was fitted with an obturator. His mandibular first molar then erupted successfully. In the second case, we treated a 12 year-old boy using orthodontic traction. This study describes children with tooth eruption disorders of the mandibular first molar in mixed dentition, and reports acceptable results regarding treatment of the impacted teeth.

Purpose: The aim of this study is to evaluate the accuracy of surgically diagnosing early gastric cancer (EGC) and lymph node metastasis, and to determine its role for performing limited surgery for EGC. Materials and Methods: We reviewed 369 patients who underwent gastrectomy for primary gastric carcinoma. The surgical diagnosis was evaluated by determining its sensitivity, specificity and accuracy, and this was compared with the preoperative examinations. Results: The sensitivity, specificity, and accuracy of the intraoperative diagnosis for EGC were 74.5%, 95.7% and 83.7%, respectively. The predictive value for EGC according to the intraoperative diagnosis was 95.7%. The surgical diagnosis of EGC showed higher specificity and a higher predictive value than preoperative examinations, which significantly reduced the risk of underestimating advanced gastric cancer (AGC) to EGC. The sensitivity, specificity, and accuracy for lymph node metastasis according to the surgical diagnosis were 73.2%, 78.1% and 76.4%, respectively. For 70 patients with a discrepancy in the diagnosis of EGC between the pre- and intra-operative diagnosis, the surgical diagnosis was correct in 63 (90%) patients, but the preoperative examinations were correct in only 7 (10%) patients. Conclusion: The surgical diagnosis showed better accuracy than the preoperative examinations for detecting EGC and lymph node metastasis. Our results suggest that the decision for conducting limited surgery based on the surgical diagnosis might reduce the risk of under-treatment of AGC to EGC better than the preoperative examinations.

From October 1993 to February 1996, 9 patients with Wolfr-Parkinson-White syndrome underwent surgical ablation of the accessory atrioventricular conduction pathways. The indications for surgical ablation we e radiofrequency ablation failure in 6 cases, multiple accessory pathways in 1 case, catheter tip fracture ducting catheter ablation in 1 case and additional procedure(redo mitral valve replacement due to valve thrombosis) in 1 case. There was no operative mortality. The postoperative complications were noted In 2 cases pericardial effusion and wound Infection. All patients had accessory atrioventricular connections ablated which were proven by surface ECG and follow-up electrophysiologic study and have remained free of symptomatic tachycardia. The indications for surgical treatment of Wolff-Parkinson-White syndrome are radiofrequency ablation failure, multiple pathways, or when additional procedures are required The present results were satisfactory.
