  • Perforator flaps have become increasingly popular in microsurgery nowadays and are being used widely for many cases of reconstruction after trauma and cancer ablation. And thoracodorsal perforator based free flap is one of them having the merits of carrying a large skin paddle with leaving intact innervation and function of the remaining latissimus dorsi muscle. We made a homogeneous thin flap excluding the main muscle with a long vascular pedicle and tried to decrease the donor site morbidity. But, it needs a long learning-curve and we have met marginal flap necrosis frequently. Besides, prolonged operation time for complete perforator dissection may be a tedious job to the microsurgeon. To overcome these disadvantages, we usually included very small portion of the latissimus dorsi muscle during this flap elevation around the pedicled 2-3 thoracodorsal perforators during this flap elevation. We performed 3 cases of thoracodorsal perforator based free flap at Hallym university sacred heart hospital between May and August 2005 for the soft tissue defect of the scalp and feet. The average flap size was $8{\times}14\;cm$. Although it is not a true perforator flap, we can get the reliability for the flap survival with much better blood circulation and save the time of one or two hours to dissect the perforators completely. All cutaneous flaps survived completely without any complication except one fatty female who had the very small superficial fat necrosis due to flap bulkiness. We believe the thoracodorsal perforator based free flap can be extended its versatility and reliability by including the very small portion of the muscle around the perforators.

  • 외상성, 혹은 선천적 결손으로 인한 함몰부에 사용한 자가 유리지방 이식은 잘 알려진 방법이다. 이를 위해 사용되는 주된 공여부는 복부나 둔부의 피하지방이었다. 그러나, 1977 년 Egyedi는 협지방대를 유경피판으로 처음 사용하였다. 협지방대는 안면골 절단술시, 협측 피판을 들어올릴 때, 혹은 이하선관 수술 같은 구강내 수술시 항상 귀찮은 구조물로써, 수술 시야를 방해한다. 협지방대는 매우 세밀한 막으로 둘러싸인 소엽형태의 볼록한 물질로, body와 네 개의 prccess들로 구성된다. 이 돌기들은 여러 근육층 사이의 충전물로 작용하며, 유아에서는 sucking시 보조작용으로, 성인에서는 윤활재로 사용되기도 한다. 본 교실에서는 협지방대를 사용하여 세 증례의 협골 함몰부에, 그리고 한 증례의 비순구 재건을 위해 사용한 바, 양호한 결과를 얻었기에 문헌고찰과 함께 증례보고를 하는 바이다.

  • 사지의 연부조직 결손으로 고려대학교 의과대학 정형외과학 교실에서 입원했던 12명의 환자 13례에 대하여 전완부 유리 피판술을 시행 후 최저 3개월에서 최고 37개월간 평균 14.3개월간 추시하여 다음과 같은 결론을 얻었다. 1. 13례 전례에서 연부조직 결손의 치료로 만족할만한 결과를 얻었다. 2. 이식피판의 크기는 평균 $54cm^2$였으며 유리피판의 평균 혈류 차단시간은 74분 이었다. 3. 술후 3례에서 합병증이 발생하였으며 3례중 2례는 동맥 문합부위에 혈전이 발생하였으나 술후 제 2일에 혈전 재거술을 시행하여 해결하였으며, 1례는 이식 정막내의 혈전으로 이식피판의 표층괴사가 발생하여 고식적인 피부이식술로 치료하였다. 4. 체중 부하를 받는 족저부의 재건에는 감각신경을 포함한 전완부 유리피판술이 좋은 방법의 하나이다. 5. 전완부 피판술은 비교적 넓은 연부조직 결손을 치료할 수 있고 이식 혈관의 내경이 커서 문합이 비교적 쉬워 숙련된 미세수술 수기를 익힌 외과의사에게는 성공률이 높은 유리피판술 중의 하나이다.

  • Purposes: Wide scars occurring on the lower face and neck are a source of both functional and esthetic problems. Consequently, we can use skin grafts, pedicled flaps, free flaps, and tissue expansion for the reconstruction of this area. Compared with other reconstruction techniques, tissue expansion is advantageous in that it enables the maintenance of a color and texture similar to that of the adjacent tissue. However, the conventional method of tissue expansion has been reported to lead to an unnatural cervicomental angle and to the deformity of adjacent structures. We have therefore made efforts to prevent these problems through the use of several operative procedures. Methods: Forty-one patients with lower facial and cervical scars underwent tissue expansion. The tissue expansion was performed using a rectangular-shaped Nagosil$^{(R)}$ tissue expansion device. On insertion of the tissue expander, the intermediate area of superficial fat layer was dissected and then the tissue expander was inserted to make a flap that was as thin as possible. In advancement of the flap, a capsule-formed by the tissue expander-was used for the interrupted fixed suture of the flap to the fascia of the platysma muscle of the neck. This procedure was performed multiple times and also performed between the flap and the periosteum of the mandible, such that the tension was removed during the suture of the flap margin. Finally, the patients were fitted with a Jobst$^{(R)}$ facial garment in order to stabilize the operation site at least twelve months. Results: The most prevalent location of the scar was the cheek (15 cases), followed by the chin in 14 cases and the neck in 12 cases. The mean size of scar was $55.7{\pm}39.4cm^2$. Conclusions: Using our procedures, we have experienced no significant deformities and have also achieved a more natural cervicomental angle in the patients.
