  • 기관연골까지만 침윤된 갑상선암에서 침윤된 기관연골을 면도식으로 깍아 내는 술식을 선택했을때 효과적인 치료방법이 되는가를 알아보기 위하여 본 연구를 실시하였다. 1979년 부터 1988년까지 10년간수술이 시행된 갑상선암환자 432예중 기관연골까지만 침윤된 환자는 16예 이였다. 남자가 3예, 여자가 13예 이었으며, 이들의 평균 연령은 55.8세 이었고, 조직학적으로는 유두상암이 14예, 여포상암이 2예 였다. 전예에서 침윤된 기관연골을 면도식으로 깍아내였으며, 수술후 보조치료로 방사성 동위원소 치료나 외부 방사선 조사를 추가하였고, 또한 갑상선 홀몬 투여로 TSH 억제 치료를 하였다. 평균 추척 기간은 67.7개월이었다. 16예중 무병생존은 4예에 불과하였고, 12예가 치료에 실패했는데 이중 7예는 갑상선암의 재발로 사망하였다. 이상의 결과로 면도식 절제술은 갑상선암이 기관연골에 침윤되었을 때의 술식으로는 부적당하며 무병 생존율을 향상시키기 위해서는 비록 표재성인 기관연골 침윤이라도 기관제술과 같은 적극적인 술식 선택이 바람직하다고 사료되었다.

  • When thyroid carcinoma invades the larynx or trachea, the proper treatment is needed because of significant morbidity and mortality due to airway obstruction. Hemoptysis and dyspnea are the result of intraluminal extension of the tumor and call for immediate investigation with endoscopic examination and CT. If the thyroid carcinoma with extracapsular spread invades only outer perichondrium of the tracheal or laryngeal cartilage, the shaving operation would be sufficient, but if the tumor invades the cartilage or if there is intraluminal invasion, it is mandatory to remove partial or total part of some aerodigestive tract structures. We retrospectively analyzed 14 surgical cases of the thyroid cancer with laryngotracheal invasion(12 papillary carcinomas and 2 anaplastic carcinomas) at the Department of Otorhinolaryngology-Head and Neck Surgery, Seoul National University Hospital. The analysis was focused on clinical manifestation, pathologic findings, types of management and results. Survival result was not adequately analyzed due to some recently operated cases.

  • During the condylar shaving procedure, the articular soft tissue cover can be removed. Author compaired the histological healing process of the articular soft tissue cover between the preservative and unpreservative group group with 45 New Zealand rabbits(Average wt. : about 2.5kg). In unpreservative group, the usual high condylar shave with the removal of soft tissue cover was performed. In the preservative group, the underlying bone, replaced in its original position and sutured. The animals were sacrified 1, 2, 3, 4, 6 weeks interval after operation. The specimens were fixed in 10% neutral formalin and decalcified, paraffin embedded and stained by Hematoxylin & Eosin, and Masson's trichrome. The obtained results were as follows. 1. The condyles of the both group were covered with an articular sop tissue layer. 2. The cartilage cells in subarticular layer has regular continuous patterns in the preservative group but frequently interrupted in the unpreservative group. 3. The incision made in the posterior part of the articular surface for the elevation of the articular soft tissue frequently caused a deformity such as the interruption of the subarticular layer of cartilage. 4. By the above findings, the preservation of articular sop tissue cover may be the effective operation method on concept of bone remodelling.

  • Perforator flaps are becoming increasingly common, and as primary thinning techniques are being developed, the need for secondary contouring of flaps is decreasing. However, many reconstructive flap procedures still incorporate secondary debulking to improve the functional and aesthetic outcomes. Direct excision, liposuction, tissue shaving with an arthroscopic cartilage shaver, and skin grafting are the four major methods used for secondary debulking. Direct excision is primarily applied in flaps where the skin is redundant, even though the volume is not excessive. However, due to the limited range of excision, performing a staged excision is recommended. Liposuction can reduce the amount of subcutaneous tissue of the flap and protect the vascular pedicles. However, the main drawback of this method is its limited ability to remove fibrotic tissues, for which the use of a shaver may be more convenient. The main drawback of using a shaver is that it is difficult to simultaneously remove excess skin. Skin grafting enables the removal of sufficient excess tissue to recover the contour of the normal limb and to improve the color match, facilitating excellent aesthetic results.

  • Purpose: Number of arthroscopic surgery is gradually increasing with development of its equipment and technique. Arthroscopic ankle surgery performed with the traction device has various complications and need more time for preparation. We investigated whether the complication rate increased when surgery was performed without the traction device, and compared the complication rate of arthroscopic surgery with the traction device. Materials and Methods: From January 2009 to June 2012, arthroscopic ankle surgery was performed without the traction device in four hundred eleven cases. There were two hundred sixty-one males and one hundred fifty females. The average age at operation was 35 years (range, 17-56), and the average follow up period was 28 months (range, 12-41). Postoperative symptoms and complications were checked. Results: There were difficulties performing arthroscopic surgery without the traction device in five cases with severe traumatic osteoarthritis. However, after burring and shaving, we had enough space to work on. Superficial peroneal nerve symptom was found in two cases, grooving of talus was found in 11, and saphenous vein injury was found in five. Since preparing for the traction device was unnecessary, we were able to save time with the mean duration of surgery of 50 minutes (range, 30-120). Conclusion: With only manual traction, we could explore the entire ankle joint without damage on cartilage. Yet, skilled arthroscopic technique will be necessary for arthroscopic surgery without the traction device.

  • 목적 : 족근관절 손상 후 동통을 호소하는 환자에서 동통의 원인을 찾아내어 적절한 치료를 시행하기는 쉽지 않다. 그러나 최근 들어 관절경 기계 및 술기가 비약적으로 발전하면서 족근관절 손상 후 나타나는 동통의 원인을 진단하고 치료하는데 관절경의 이용이 증가되고 있다. 이 연구의 목적은 족근관절 골절 치료 후 만성 동통의 원인 진단과 치료에 대한 족근관절경의 유용성을 알아보려는 것이다. 대상 및 방법 : 1997년 1월부터 1998년 6월까지 족근관절 골절 치료 후 족근관절의 지속적인 동통과 운동 제한으로 최소 3개월동안 물리 치료를 받았던 환자중 증상의 호전이 없어 족근관절경을 시행한 17례를 분석하였다. 결과 : 방사선적 검사에서 관절내 유리체가 2례, 골관절염의 진행 정도에 의한 분류상 Crade 0 3례, Crade I 8례, Crade II 6례, Grade III는 없었으며, 족근관절 전방부의 골극은 14례에서 관찰되었다. 관절경 소견상 비후성 활액막염이 전례에서, 연부조직 충돌 증후군이 총 13례, 관절내 유리체 5례 그리고 연골 병변 4례가 관찰되었다. 관절경적 치료로 골극의 골 연마술 8례, 연부 조직 제거술은 13례, 관절내 유리체 제거술이 5례에서 시행되었다. Evanski와 Waugh score상 족근관절경 술전 기능 34점, 동통 17.4점, 운동 범위 7.3점으로 평균 58.7점에서 술후 기능 38.4점, 동통 28.4점, 운동 범위 7.8점으로 평균 74.6점이었으며 전체 17례 중 14례$(82\%)$에서 증상이 호전되었다. 합병증은 전례에서 보이지 않았다. 결론 : 족근관절 골절 치료후 만성적 족근관절 동통이나 기능 장애가 있는 환자에서 진단과 치료를 동시에 시행할 수 있는 관절경술은 매우 유용한 방법으로 사료된다.
