Sutures support wound healing during the initial phase. As the tensile strength of a wound increases, the need for the presence of sutures becomes less important. For this reason, absorbable suture materials have been sought. Nowadays, commonly used suture materials are Chromic Catgut, Coated Vicryl, and PDS. Among these materials, Coated Vicryl is the most popular. Studies were conducted to compare the handling properties, reliability of knots, wound healing, and tissue reactivity(Inflammation, Fibroblast proliferation, Collagen deposition, Giant cell reaction, Absorption) between AILEE vicryl and ETHICON vicryl. We used twelve purebred New Zealand white rabbits, and biopsied the tissue at three, seven, fourteen, and thirty days post implantation. The results showed that both were supple and easy to handle and tie, and gross and histologic differences were not apparent.

Lower extremity injuries are frequently accompanied with large soft-tissue defects. Such Injuries are difficult to manage for its poor vascularity, rigid tissue distensibility, easy infectability and a relatively long healing period. Also, osteomyelitis, and/or non-union of the fractured bones are relatively common in lower extremity injuries and its weight-bearing role should be considered. Therefore, it is important to select appropriate reconstruction method of the lower extremities, which is applicable to a variety of surgical techniques according to these considerations. The goal of flap coverage in the lower extremity should not only be satisfactory wound coverage, but also acceptable appearance and minimal donor site morbidity. In this article, we have tried to establish a reconstruction method in the lower extremity based on our experiences and clinical analysis of soft tissue reconstruction using free muscle flap transfer in 27 cases from Jan. 2000 to Dec. 2002. The results showed 96% flap survival, and flap failure noted in one of the cases due to vascular insufficiency. In conclusion, we believe that in cases of lower extremity soft-tissue defects especially with open comminuted fractures and infections, muscle free flaps should be considered as the first line of treatment.

The W-plastic scar revision is the surgical technique by which a straight or curved antitension line(ATL) linear scar is changed into a zigzag pattern without tissue rotation. The scar is improved mainly by breaking up the bowstring effect of the long straight scar contracture, by redirecting the course of the malaligned scar and by unscarred tissue blending into the W-shaped scar. Although this technique is not easy, takes more operation time, and sacrifices some normal skin to increase the tensil strength of skin, ATL linear scar in forehead, cheek and chin can be treated effectively with it.
인두피부누공의 치료를 위한 요골전완유리피판의 새로운 도안

Pharyngocutaneous fistula is a dreaded complication of ablative surgery of the aerodigestive tract such as pharynx and larynx. This is a common problem for the surgeon. We present two patients with glottic carcinoma who suffered from pharyngocutaneous fistulae which developed after total laryngectomy and radiation therapy. The fistulae were reconstructed with newly designed radial forearm free flaps. A radial -forearm free flap larger than the defect was elevated and the flap, except the central inner lining area, was deepithelized. Skin around the defect was removed and then deepithelized. The inner lining was made with the central skin paddle. The deepithelized area was placed over the deskinned area around the defect. The final outer covering of skin graft was extended to the surrounding deepithelized areas. We obtained a obliteration of the fistulae and natural neck contour using this method. This new design has the following advantages; large contact area between the flap and the inflammed surrounding tissue, discontinuity between the suture lines of the inner lining and the outer covering, and reinforcement of suture line of outer covering with skin graft. We believe that this is a useful method for reconstructing irradiated pharyngocutaneous fistulae.

Surgical excision of the subcutaneous tissues, with or without skin excision in the axillary hair-bearing area, has been the treatment of choice for Treating axillary a osmidrosis for the several decades. However, long periods of postoperative immobilization of a shoulder joint, partial necrosis of skin flaps or hematoma and the possibility of unsightly scars are frequent complications. For the purpose of reducing these complications, we performed ultrasonic aspiration of subcutaneous fat of the axilla, including the apocrine gland, using ultrasonic liposuction technique under confirmation of endoscopy via one small skin incision. From November 1997 to December 1998, a total of 134 patients (93 women and 41 men) received surgery for bilateral axillary osmidrosis on an outpatient basis. Sixty patients were evaluated more than 6 months after surgery. Among these patients, 6patients complained of a persistent foul odor(10%). Five patients received secondary ultrasonic aspiration for persistent foul odor and were then cured. We concluded that our method has several advantages such as 1) preservation of skin flap vascularity for the prevention of flap necrosis and axillary hair, 2) minimal scarring and bleeding, 3) shorter operation time and postoperative immobilization of the shoulder joint, 4) increased patient comfort, and 5) a safer operative method for recurred cases as a secondary method.
구강 협부 점막에 생긴 국한성 림프관종(Lymphangioma circumscriptum)의 임상 증례 보고
유원민,오승훈,나동균,박병윤 大韓成形外科學會 1998 Archives of Plastic Surgery Vol.25 No.1
Lymphangioma circumscriptum is a benign disorder of lymphatic channels. The pathologic findings consist of a collection of deep, sequestered subcutaneous lymphatic cisterns which are encircled by smooth muscle. The lymphatic cisterns are communicating with superficial clusters of vesicles through dilated lymphatic channels. The etiology of this lesion is unclear ; however, lymphatic obstruction has been suggested as a possible cause. It is characterized clinically by grouped vesicles, some of which may be filled with serosanguinous fluid. It is an unpleasant, but benign condition conventionally managed by wide local excision, which provides symptom control and often prevents recurrence. Neither long term complication nor association with squamous cell carcinoma has been previously documented. Some cases were reported following mastectomy and radiation therapy or radiation therapy for squamous cell carcinoma of the cervix. We present a 17-year-old patient with lymphangioma circumscriptum developed on buccal mucosa, which developed 3 months after innervated serratus anterior muscle free flap for functional reconstruction of cheek. We suppose that it was caused not only by lymphatic blockage resulted from wide operation but also by chronic masticating local irritation. In review of literatures, we didn't have found any report of lymphangioma circumscriptum developed on buccal mucosa.
