Purpose: The rectus abdominis musculocutaneous (RAM) flap has contributed to the efficient reconstruction of soft tissue defects. The flap has the advantage of easy dissection, minimal donor site morbidity, and the constant vascular anatomy with long pedicle. Authors used the free RAM flap to reconstruct multi-located soft tissue defects while still considering functionality and aesthetics. We present the long-term outcomes and versatility of free RAM flaps. Materials and Methods: From 1994 to 2004, all patients who underwent soft tissue reconstruction with free RAM flap were reviewed retrospectively. The site of the reconstruction, vessels of anastomosis, type of RAM flap, and outcomes, including flap success rate, hospital stay after flap transfer, conduction of secondary procedure, flap complications, and donor-site complications were analyzed. Results: Twenty-one patients underwent 24 free RAM flaps in site of breast, face, upper extremity and lower extremity. Mean follow-up period was 36.1 months (range, 3~156 months). The overall success rate was 92% with only a loss of 2 flaps. Minor complications related to transferred flaps were necrosis of 2 partial flaps, hematoma formation in 3 cases, and a wound infection in 1 case. Donor site morbidity was not observed. Debulking surgery was performed in 4 patients, and scar revision was performed in 3 patients. Conclusion: Free RAM flap is a workhorse flap for general soft-tissue reconstruction with minimal donor site morbidity with aesthetically good results. Thus, the free RAM flaps are versatile, and sturdy for any sites of soft-tissue where reconstruction could be performed.

Background: To evaluate the versatility and reach of modified nasolabial flap used in reconstruction of defects created in and around the oral cavity. Methods: A total number of 20 cases were selected. Out of which 13 were males and 7 females. The age of these patients ranged from 24-63 years. 29 modified nasolabial flaps were raised in twenty patients. Based on clinical and histopathological examination, out of 20 patients, 14 patients were diagnosed with oral submucous fibrosis, 3 with verrucous carcinoma, 1 with squamous papilloma, 1 with oro-antral fistula and 1 with traumatic loss of lower lip. Results: Minimum preoperative interincisal distance (IID) was 0 mm and maximum was 15 mm with mean of $6.00{\pm}4.76mm$ in patients with oral submucous fibrosis and 12 months postoperatively minimum IID was 16 mm and maximum was 41 mm with mean of $28.00{\pm}8.96mm$. In one case, dehiscence (3.4%) was noted on the anterior tip for which tip revision was done. Bulky appearance of the flap intraorally was observed in 2 cases (6.9%). Five (17.2%) among the 29 flaps had visible scar at the donor site postoperatively up to 3 months. Conclusion: Numerous reconstructive techniques have been employed in the reconstruction of small to intermediate sized defects of oral cavity. Modified nasolabial flap is a versatile flap which has robust vascularity and can be successfully used with minimal complications. It can be rotated intraorally to extend from the soft palate to the lip. Thus, it can be used efficiently to treat the small defects of the oral cavity as well as recreating lost lip structure.

Purpose: Aging changes of midface include drooping of lower lid, wrinkles of malar area, orbitomalar groove and deepening of nasolabial fold from drooping of malar fat pad. Improvement of lower lid can be achieved through lower blepharoplasty, but improvement of cheek can not be gained. Superficial subciliary cheek lift(by Moelleken, 1996) is a method that lifts malar fat pad through extended subciliary incision. We obtained simultaneous improvement of lower lid, malar wrinkles and orbitomalar groove with modification of this technique. Methods: From December 2003 to January 2006, we performed this method on 21 patients among volunteers for lower blepharoplasty who wanted to correct orbitomalar groove and malar wrinkles. Under local anesthesia, lateral extension of subciliary incision is done 1cm from the lateral orbital rim. Skin-muscle flap is elevated, and dealing of orbital fat and septum is the same as with ordinary lower blepharoplasty. After downward subcutaneous dissection through extended incision, exposing the upper 1/3 level of malar fat pad, superolateral fixation is done to superior deep temporal fascia. Excision of the upper part of fat pad is performed, if needed. After excision of overlapped skin-muscle flap, skin closure is done. Results: We obtained satisfactory results with this simple method for improvement of orbitomalar groove and malar wrinkles among patients for lower blepharoplasty. During a follow-up period of 5 months on the average, no revision was performed. Conclusion: Under local anesthesia, lower blepharoplasty and improvement of orbitomalar groove and malar wrinkles can be achieved at the same time. It is good for patients who do not want conventional midface-lifting. But surgeons should select patients and perform cautiously for it may leave a scar of the extended incision that require over 2 months for maturation and it is insufficient for improvement of nasolabial fold compared to conventional mid face-lifts.

Purpose: The latissimus dorsi muscle flap is a versatile flap used in a variety of reconstructive procedures. The most common complication of LD muscle flap is donor site seroma, reported to occur in 20 to 79 percent of cases. The formation of dead space under the flap is intimately associated with seroma formation. The authors think that the use of progressive tension suture at closing donor site can decrease the formation of dead space and ultimately reduce the incidence of donor site seroma. Methods: A retrospective review was performed with 38 patients who underwent latissimus dorsi muscle harvest for breast reconstruction from March 2003 to September 2004. Progressive tension sutures were used during donor site closure in 22 patients. This group was compared with controls group(16 patients) who underwent latissimus dorsi muscle harvest without using this technique. Operation time, length of hospital stay, period of drainage, complication, and satisfaction about postoperative scar of donor site were examined. Results: The average length of hospital stay was 10.2 days and 12.7 days, and the mean duration of drainage were 7.3 days and 11.7 days in each progressive suture group and control group. These results were statistically significant (p<0.05). In the 22 patients who underwent progressive tension suture, none had seroma, hematoma or skin necrosis. In control group(16 patients), there happened one seroma formation and one partial skin necrosis. These complications were healed by aspiration of seroma and wound revision. The patients' satisfaction was not statistically significant, but the higher points were given by the patients who underwent progressive tension suture. Conclusion: This technique, progressive tension suture, is an effective method to reduce or eliminate donor site seroma, which is the most common complication associated with latissimus dorsi muscle harvest.

A clinical analysis was performed on 49 cases of the benign esophageal diseases experienced at Department of Thoracic and Cardiovascular Surgery, Seoul National University Hospital during 7 year period from 1977 to 1983. Of 49 cases Of the benign esophageal diseases, there were 19 patients of esophageal stricture, 11 of achalasia, 6 of perforation, 3 of bronchoesophageal fistula, 3 of esophageal perforation, 3 of esophageal leiomyoma and one of esophageal foreign body. Twenty three patients were male and 26 were female. Ages ranged from 4 years to 74 years with the average age of 34.7 years. Of 19 patients of esophageal strictures, 7 patients were male and 12 were female and ages ranged from 6 years to 74 years with the average being 33.8 years. Causes of esophageal strictures were corrosive of esophageal strictures were dysphagia, vomiting, general weakness, weight loss and pain that order and developed on several different parts of esophagus. Operations were performed in 18 cases, of whom 7 patients were performed by esophagocologastrostomy, 4 gastrostomy, 4 esophagogastrostomy, 1 esophageal resection and esophagoesophagostomy, 1 esophagotomy and dilatation and 1 scar revision. Five patients had one or two complications; 2 anastomotic leakage, 1 wound infection, 1 localized empyema, 1 bilateral pneumothorax and 1 respiratory failure. One patient expired due to respiratory failure arising from aspiration pneumonia. The average age of achalasia patients was 33.1 years and symptom durations were from 2 months to 10 years with the average of 3.3 years. Main symptoms were dysphagia, vomiting, weight loss, pain and cough in that order. Modified Hellers myotomy was performed in 11 patients with one complication of restenosis. One patient was operated on by using longitudinal incision and transverse sutures with good result. Of 6 patient of esophageal diverticulum, 2 patients were traction diverticulum on the midesophagus, 2 were pulsion diverticulum on the midesophagus and 2 were pulsion diverticulum on the lower esophagus. Diverticulectomy was performed on 2 cases of traction diverticulum and esophagocardiomyotomy with or without diverticulectomy was erformed on 4 cases of pulsion diverticulum with good results. Of 5 patients of congenital bronchoesophageal fistula, the chief complaints were productive cough in 4 patients and hematemesis without respiratory symptoms in one patient. Two patients were operated on by using fistulectomy only and 3 by fistulectomy with pulmonary lobectomy. Of 3 patients of esophageal perforation, causes were foreign body ingestion, esophageal stricture after ECG and corrosive esophagitis. Two patient were operated on by using drainage and gastrostomy with symptomatic improvement but one patient died due to septic shock after thoracotomy. Three patients of esophageal leiomyoma were all male and 2 patients were operated on by using enucleation and one by distal esophagectomy with esophagogastrostomy. In one patient of esophageal foreign body, it was removed by esophagotomy through the right thoracotomy.

Purpose: To correct the upper lip depression after the correction of unilateral cleft lip, autologous grafts such as bone, dermal, fascial grafts and fat injections or alloplastic implants are used. Transplanted bones, dermis and fascia have a tendency to be absorbed and have donor morbidity. Fat injections are absorbed inconsistently and alloplastic implants have problems such as foreign body reactions, protrusions and infections. Authors corrected the upper lip depression using conchal cartilage graft in unilateral cleft lip deformity and the results was analysed with photos. Methods: 26-unilateral cleft lip and 2-microform cleft lip cases, totally 28 cases were performed. Their mean age was 21.89 years. The male and female cases were 12 and 16, respectively. Under anesthesia (general: 18 cases and local: 10 cases), cavum conchae (n=8), cymba conchae (n=16) and whole conchae (n=4) were harvested. Transversely cut the margin of the obtained cartilage, we cut out the most bent portion and put a partial-thickness incision on concave surface in cases of excessive convexity. Then, we performed the onlay graft of the conchal cartilage via scar revision site in unilateral cleft lip and via the reconstruction site of the cupid bow in microform cleft lip. The augmentation of the upper lip was evaluated with photos. Adapting the baseline connecting between the both cheilions as a horizontal standard line, we measured the highest point among the tangents between the upper lip and nose (point a), the lowest point (point c), the middle point between a and c (point b) and the vertical line from the alare (point d) to the horizontal standard line. To assess the postoperative symmetry, we compared cleft side upper lip contour index (%) A,B,C,D=(a,b,c,d)-ch ${\times}$ 100/(ch-ch) and non-cleft side upper lip contour index (%) A',B',C',D'= (a',b',c',d')-ch ${\times}$ 100 / (ch-ch).h) Results: After the surgery, no complication was found except in one case which double layers graft performed in the cleft lip deformity, the lateral portion was protruded. The upper lip contour index, the difference of A and A' were-0.83%, and thus the mild depression was persisted. Difference of B and B', C and C', D and D' were 0.83%, 1.07%, 0.90%. There were statistically significant difference, and thus the depression of upper lip were improved generally. Conclusion: Authors performed the onlay graft of the conchal cartilage in unilateral cleft lip deformity and found that the depression of the upper lip was well corrected except the uppermost part when photogrammetrically analyzed.

목적: 상완골 근위부 절제 후 다양한 재건술이 시도되었으나 역 견관절 전치환술의 도입으로 기능적 결과의 향상이 있었다. 그러나 광범위한 골결손을 동반한 경우에도 이 방법을 적용할 수 있는지와 비수술적 치료 실패 후 지연 재건하면 기능회복의 정도가 어떤지에 대해서는 불확실하다. 대상 및 방법: 상완골 근위부 재건술 후 실패한 11예는 중첩 동종골과 역 견관절 전치환술의 조합술을, 비수술적 치료가 실패한 6예는 지연 역 견관절 전치환술을 시행하였다. 수술 전, 후 기능적 결과를 비교하였으며 합병증을 기술하였다. 결과: 역 견관절 전치환술과 동종골 조합술로 일차 수술이 실패한 11예 전부에서 안정된 재건술이 가능하였으며 수술 전 주 증상도 해소되었다. 골 접합부 평균 골유합 기간은 5.5개월이었다. 수술 전, 후 근골격계 기능 점수는 평균 20.3점에서 25.7점으로 증가하였다. 일차 수술 후 4년 이내에 역 견관절 전치환술로 치환한 6예 중 4예에서 $90^{\circ}$ 이상의 상지 거상이 가능하였으며, 일차 수술 후 4년 이후에 수술한 5예는 견관절의 안정성은 얻었으나 전부 $90^{\circ}$ 이상 거상이 불가능하였다. 합병증은 관절탈구와 무균성 감염이 각각 1예로 폴리에틸렌 교체와 반흔 조직 절제술로 치료하였다. 비수술적 치료 실패로 지연 역 견관절 전치환술을 한 6예에서 기능평가 점수는 향상되었으나 전 예에서 상지의 $90^{\circ}$ 이상 거상은 불가능하였다. 결론: 중첩 동종골과 역 견관절 전치환술의 조합술은 대량의 상완골 골결손이 발생한 환자에서 간단하고 합병증이 적은 골질 회복방법으로 생각된다. 진단 시 근위 상완골 전 절제가 필요한 전이성 골종양 환자는 조기에 역 견관절 전치환술을 하는 것이 기능유지에 도움이 될 것으로 생각된다.
