Elevating thin flaps has long been a goal of reconstructive surgeons. Thin flaps have numerous advantages in reconstruction. In this study, we present a surgical method for elevating a thin flap and demonstrate the safety of the procedure. A retrospective review was performed of the electronic medical records of patients who underwent thin flap elevation for lower extremity reconstruction from April 2016 to September 2016 at the Department of Plastic Surgery of Asan Medical Center. All flaps included in this study were elevated above the superficial fascia. A total of 15 superficial circumflex iliac artery free flaps and 13 anterolateral thigh free flaps were enrolled in the study. The total complication rate was 17.56% (n=5), with total loss of the flap in one patient (3.57%) and partial necrosis of the flap in four patients (14.28%). No wound dehiscence or graft loss at the donor wound took place. Elevation above the superficial fascia is not inferior in terms of flap necrosis risk and is superior for reducing donor site morbidity. In addition to its safety, it yields good aesthetic results.

Urethral reconstruction is a problematic issue, thus its management can be challenging. Different methods using various materials were introduced for urethral reconstruction. The authors have made some changes in the groin flap surgery, affording more successful urethral reconstruction for defects of long urethra and penile soft tissue. A 45-year-old male requested both functional and cosmetic reconstruction of his defected penis, caused by an iatrogenic urethral injury and chronic infection following removal of paraffin self-injected on the penile shaft. The defect affected the full length of the penile urethra, corpus spongiosum, and prepuce. A groin flap was designed, measuring $28{\times}10cm$. The most distal flap was utilized for the construction of the luminal surface of the neourethra; relaxed length measuring 8 cm, and the lumen wide enough. Competent external meatus and neourethra was confirmed by retrograde cystogram and the patient voided with sufficient urine caliber up to 2 years follow-up. This operative technique has advantages. Donor sites have non-hair bearing skin for the neourethra and minimal or almost notrecognizable donor site morbidity. After surgery, the patient was relieved from voiding difficulties combined with psychological stress. The author would like to introduce a unique approach for the urethral and ventral phalloplasty using the groin flap.

성공적인 전방십자인대 재건술을 얻기 위해 수술 전 계획, 수술수기, 수술 후 재활 등 여러 가지 요소가 관여한다. 그리고 좋은 결과를 얻기 위해서 수술 중 이식건의 선택, 고정, 처리 방법, 성숙, 본체골에 병합, 장력 등을 고려해야 한다. 이식건을 선택할 때 이식건의 강도, 이식건의 고정방법, 고정부위 치유, 공유 부위 이환, 이식건의 표면적 크기 등을 고려해야 한다. 이식건에는 자가건과 동종건의 두 가지가 있다. 자가 슬개건, 슬괵건, 대퇴사두건 등 사용할 수 있는 자가건은 여러 가지가 있으며 각각의 장·단점을 가지고 있다. 최근 국내에서 동종건의 사용빈도가 높아지고 있는데 공여부의 이환이 없고, 수술 시간이 짧고, 수술 후 통증이 적고, 재료가 다양한 장점이 있다. 하지만 동종건이 자가건보다 장기간 추적 결과가 더 좋다는 보고는 없다. 동종건은 골과의 합병이 오래 걸리고, 불완전하며, 인대 재형성이 늦고, 생역학적으로 자가건보다 강도가 낮으며, 면역반응의 위험성이 높고, 질병 전파의 가능성 등 원초적인 제한점을 가지고 있다. 그래서 장기간 결과에서 실패율이 높고 이식건의 성숙도가 자가건보다 좋지 않다. 그러므로 동종건은 자가건의 대용이 될 수 있지만 자가건을 사용할 수 없을 때, 여러 가지 인대 재건술이 필요한 경우를 제외하고 자가건을 사용하도록 하는 것이 좋다. 만약 적절한 크기와 굵기의 자가건을 얻을 수 있다면 자가건을 사용한 적절한 고정방법을 선택하고 수술 후 재활을 하면 동종건을 사용한 결과보다 우수한 결과를 얻을 것으로 생각된다.

Reconstruction of soft tissue defect of knee joint area has been remained a challenging task for plastic surgeons. The earlier the normal tissue saved and the necrotic tissue removed, the less the patients had complications and functional disability. But such defects are difficult to manage for its poor vascularity, rigid tissue distensibility, easy infectability and a relatively long healing period. The goal of flap coverage in the knee joint should not only be satisfactory wound coverage, but also acceptable appearance and minimal donor site morbidity. We have treated five cases using the anterolateral thigh perforator flaps for reconstruction successfully. In conclusion, we believe that in cases of knee joint area soft tissue defects, flaps like anterolateral thigh perforator flap should be considered as the first line of treatment.

Rehabilitation of the paralyzed face as a result of trauma or surgery remains a daunting task. Complete restoration of emotionally driven symmetric facial motion is still unobtainable, but current techniques have enhanced our ability to improve this emotionally traumatic deficit. Problems of mass movement and synkinesis still plague even the best reconstructions. The reconstructive techniques used still represent a compromise between obtainable symmetry and motion at the expense of donor site deficits, but current techniques continue to refine and limit this morbidity. In chronically paralyzed face, direct nerve anastomosis, nerve graft, or microvascular-muscle graft is not always possible. In this case, regional muscle transposition is tried to reanimate the eyelid and lower face. Regional muscle includes maseeter muscle, temporalis muscle and anterior belly of the digastric muscle. Temporalis muscle is preferred because it is long, flat, pliable and wide-motion of excursion. In order to reanimate the upper and lower eyelid, Upper eyelid Gold weight implantion and lower eyelid shortening and tightening is mainly used recently, because this method is very simple, easy and reliable.

Various types of flaps including local flaps, pedicle flaps and free flap have been used to reconstruct hand soft tissue defects, but each flaps have some limitation and disadvantages. The reverse posterior interosseous artery flap described by Zancolli and Angrigiani have some advantages : preserving the major artery of the hand, minimal donor site morbidity and thin skin. From May 1999 to May 2001, we reconstructed 18 cases of hand defects in industrial injury with reverse posterior interosseous artery flaps and partial distal part necrosis of flaps due to infection developed in a case but other 17 cases survived completely without any specific complication.

Among the various surgical treatment methods for osteochondral lesions of the talus, autologous osteochondral transplantation (AOT) is a useful procedure in cases of a large defect, subchondral cyst, and failed primary bone marrow stimulation procedure. Although bone marrow stimulation alone may not regenerate the damaged plate sufficiently, AOT has the advantage of being able to replace the subchondral bone plate and cartilage with a new one at a same time. Nevertheless, postoperative cyst formation or pain may persist and donor site morbidity is still a limitation of AOT.

Simple or complex defects in the lower leg, and especially in its distal third, continue to be a challenging task for reconstructive surgeons. A variety of flaps were used in the attempt to achieve excellence in form and function. After a long evolution of the reconstructive methods, including random pattern flaps, axial pattern flaps, musculocutaneous flaps and fasciocutaneous flaps, the reappraisal of the works of Manchot and Salmon by Taylor and Palmer opened the era of perforator flaps. This era began in 1989, when Koshima and Soeda, and separately Kroll and Rosenfield described the first applications of such flaps. Perforator flaps, whether free or pedicled, gained a high popularity due to their main advantages: decreasing donor-site morbidity and improving aesthetic outcome. The use as local perforator flaps in lower leg was possible due to a better understanding of the cutaneous circulation, leg vascular anatomy, angiosome and perforasome concepts, as well as innovations in flaps design. This review will describe the evolution, anatomy, flap design, and technique of the main distally pedicled propeller perforator flaps used in the reconstruction of defects in the distal third of the lower leg and foot.

골의 퇴축 혹은 수술시의 절제로 인해 임플란트를 식립하기엔 불충분한 악골을 가진 환자에 있어서 골 이식술의 필요성은 오랫동안 논의 되어왔다. 골이식술은 악골의 전체 두께(full thickness)결손시 연결성(continuity)의 수복, 혹은 표면(surface)에서의 골상실시 보강(augmentation)목적으로 쓰일 수 있다. 따라서 술자들은 임플란트를 식립하기에 불충분한 악골을 가진 환자에 있어 골 이식술에 권유하게된다. 그러나, 골 이식술은 donor site 의 morbidity혹은 수술에 대한 두려운, 추가되는 비용에 대한 염려등으로 인해 환자에 의해 거부될 때가 종종 있다. 악골 결손으로 인해 골이식없이는 임플란트를 식립하기 어려운 경우에 있어서도 임플란트 술식이 여전히 해결책이 될 수 있을까? 다음의 두가지 증례를 통해 저자등은 골이식술 없이는 임플란트르 식립하기 어려운 경우에 있어서도 임플란트 술식이 여전히 치료방법으로서 의미가 있었음을 보고하는 바이다.

Tongue reconstruction after oncologic resection with free flap is important to conserve function and shape. Vertical rectus myocutaneous free flap is usually used for total tongue reconstruction, but our patient was thin and primary closure after flap elevation seemed hard. So we used anterolateral thigh free flap to reduce donor site morbidity and to maintain bulk of the tongue as much as possible. Deepithelization of both middle side of flap and folding was done to mimic normal tongue base's shape and volume. Flap survived without complication and patient underwent concurrent chemoradiation therapy three weeks after surgery. Anterolateral thigh free flap can be good candidate for total tongue reconstruction especially in thin patient.
