The gracilis muscle is well suited to small and medium-sized soft tissue defects that cannot be adequately handled by simple rotational flaps and it will conform well to irregular contours, can be split longitudinally at both ends to allow cavities and awkwardly shaped spaces and can be transferred in part or in whole. The gracilis muscle used as a free muscle or musculocutaneous flap is small with a long, narrow contour and its vascular pedicle is a terminal branch of the medial femoral circumflex artery and vein. The aims of soft tissue reconstruction are to cover soft tissue defects, to clear up infection and to prepare for further surgical procedures. Authors have performed 12 gracilis muscle flaps in the lower extremities at Chonbuk National University Hospital from June 1994 through March 1998. The results were as follows. 1. 11 cases of 12(91.7%) were sustained from the crushing injury and secondary complications from the traffic accident. 2. The microsurgical anastomosis of one artery and two veins have performed in 6 cases(50%) of 12 and 11(91.7%) cases of 12 were successful at the third postoperative week and in the final result. 3. Gracilis muscle flap is the infetion-resistant and aesthetically acceptable performed in the lower leg 1/3 and the foot.

Purpose: Pink gingival esthetic especially on the anterior teeth has been an important success criterion in implant-supported restoration. Inter-implant papillae are a critical factor for implant esthetics, and various techniques for inter-implant papilla reconstruction have been introduced. The aim of this study is to suggest and evaluate a surgical technique for reconstructing inter-implant papillae. Methods: A 28-year-old man had an implant placed on the #13 and #14 area. Four months after implant placement, a second stage surgery was planned for inter-implant papilla reconstruction. At the time of the abutment connection, I-type incisions were performed on the #13i & #14i area followed by full-thickness flap elevation and connection of a healing abutment on underlying fixtures without suture. Results: Two weeks after the second stage implant surgery, soft tissue augmentation between the two implants was achieved. Conclusions: I-shaped incisions for papilla reconstruction performed during the second stage implant surgery were useful for inter-implant papilla reconstruction and showed a good esthetic result.

The nasolabial flap has been used for reconstruction of moderate size intraoral defects. The nasolabial fold area provides an ample supply of tissue with a good color and texture match. The nasolabial flap classified advancement flap, inferiorly-based flap, superiorly-based flap. The flap is based inferiorly, so that it can easily be rotated to the intraoral defects. The nasolabial flap is chosen for the repair of various intraoral defects because of its simple elevation, proximity to the defect and its rich subcutaneous blood supply of a island flap. The subjects were 6 patients with nasolabial flap, who had reconstruction of moderate size intraoral defects. We have found the inferiorly-based nasolabial flap with a subcutaneous pedicle useful in the primary repair of surgical defects of the buccal mucosa, edentulous mandibular ridge, maxillary alveolus area and soft palate in these patients. There was no complication except one case. Intraoral hair growth was a minor problem of this patient. We thought that the inferiorly-based nasolabial flap is a useful technique for reconstruction of various intraoral defects.

Diabetic foot ulcers are a severe complication of diabetes, and their management requires a multidisciplinary approach for optimal management. When treating these ulcers, limb salvage remains the ultimate goal. In this article, we present the "hanging" free flap for the reconstruction of chronic lower extremity diabetic ulcers. This two-staged approach involves standard free flap harvest and inset; however, following inset the "hanging" pedicle is covered within a skin graft instead of making extraneous incisions within the undisturbed soft tissues or tunnels that can compress the vessels. After incorporation, a second-stage surgery is performed in 4 to 6 weeks which entails pedicle division, flap inset revision, and end-to-end reconstruction of the recipient vessel. Besides decreasing the number of incisions on diabetic patients, our novel technique utilizing the "hanging" pedicle simplifies flap monitoring and inset and allows reconstruction of recipient vessels to reestablish distal blood flow.

Necrotizing fasciitis is an uncommon yet fatal soft tissue infection. Current recommended treatment includes antibiotics with repeat surgical exploration and wound debridement followed by reconstruction. In burn patients, the Meek micrograft has demonstrated a higher true expansion ratio, faster reepithelialization rate, more resilient toward infection, and reduced risk of graft failure as compared with meshed graft. To our best knowledge, the use of Meek micrografting technique in reconstruction of postdebridement wounds of necrotizing fasciitis has not been reported. Hereby, we present a case of a 57-year-old gentleman who was referred to us for wound reconstruction after surgical debridement of Fournier's gangrene and extensive necrotizing fasciitis involving the anterior abdomen and bilateral femoral region. Meek micrografting technique was used to reconstruct the anterior abdomen as the wound bed was large. Although the graft was complicated with a small area of localized infection, it did not spread across the entire graft and was successfully treated with topical antibiotics and regular wound dressing. In our case, wound reconstruction using Meek micrografting technique in a patient with extensive necrotizing fasciitis was successful and showed positive outcome. Therefore, we suggest further studies to be conducted to investigate the applications and outcomes of the Meek micrografting technique, especially in patients with extensive wound bed and limited donor site availability.

The aim of surgery for all parotid masses is directed toward total removal of the tumor with adequate safe margins of adjacent normal tissue and preservation of the facial nerve whenever possible. Reconstructive procedures following parotidectomy for benign or low grade malignant lesions are most commonly necessary if soft tissue deficits appear at the angle of the mandible below the earlobe as a major cosmetic deformity. This is a report of Z4 cases with a diagnosis of parotid tumor who were treated using various surgical procedures at Department of Plastic and Reconstructive Surgery, Hanyang University Hospital over the period of 4 years from January, 1983 to December, 1986. Among 24 cases, 11 cases were reconstructed by Sternocleidomastoid muscle flap at the same time that extirpative surgery is outlined. The advantage of Sternocleidomastoid muscle flap is the coverage of the facial nerve, so adhesion between the facial nerve and skin was prevented. Absorption and loss of bulk was not found such as dermofat graft. It was a simple method. Neither donor site defect nor sternocleidomastoid muscle deformity was developed. Sternocleidomastoid muscle flap have been found satisfactory in maintaining filled-out soft tissue hollows with good result cosmetically and functionally.

Soft-tissue reconstruction of the foot and ankle has long been a challenge for reconstructive surgeons. Limitations in the available local tissue and donor-site morbidity restrict the options. In an effort to solve these difficult problems, the authors have begun to use a subcutaneous fascial pedicled lateral supramalleolar flap. This report presents the authors' experience with five patients treated with this flap. The patients’ ages ranged from 26 to 72 years; four of the patients were male and one was female. The cause of the soft-tissue defects involved acute trauma and malignant melanom. All flaps survived and provided satisfactory coverage of the defect. Compared with the classic lateral supramalleolar flap, when the perforating branch is interrupted in its course, it is possible to elevate this subcutaneous fascial pedicled flap. The distally based flap with a compound pedicle which is continuous with a vascular axis and a band of subcutaneous fascial pedicle has long pedicle. This procedure is valuable for remote defect of the foot. It is believed that this flap is versatile and effective and is a good addition to the available techniques used by reconstructive surgeons for coverage of the foot and ankle.

It is so hard to obtain optimal anterior esthetics in the implant prosthesis. This is not only because of hard and soft tissue problem such as alveolar bone resorption and interdental papilla loss but also because of prosthetic limitation related to marginal exposure of metal abutment and metal ceramics and low transillumination. In this case, guided soft tissue healing is obtained using a long term provisional restoration with soft and hard tissue augmentation or immediate implantation. Then, this healed tissue is transferred to final master model using a customized impression coping and the implant is restored with a customized zirconia abutment and a all ceramics. This case presents satisfying result esthetically and functionally.

Background The mandible is an important structure that is located in the lower third of the face. Large mandibular defects after tumor resection cause loss of its function. This study assessed the outcomes and tumor recurrence after immediate mandibular reconstruction using a free fibula osteocutaneous flap following radical resection of ameloblastoma. Methods This is a retrospective non-randomized study of outcomes and tumor recurrence of all patients diagnosed with mandibular ameloblastoma from August 1997 until August 2017 (20 years) requiring free fibula osteocutaneous flap reconstruction at a single institution. The patients were identified through an electronic operative database; subsequently, their medical records and photo documentation were retrieved. Results Twenty-seven patients were included in this study. Eighteen patients were male, while nine were female. The majority of the patients (48.1%) were in their third decade of life when they were diagnosed with ameloblastoma. All of them underwent radical resection of the tumor with a surgical margin of 2 cm (hemimandibulectomy in cases with a large tumor) and immediate mandibular reconstruction with a free fibula osteocutaneous flap. Two patients required revision of a vascular anastomosis due to venous thrombosis postoperatively, while one patient developed a flap recipient site infection. The flap success rate was 100%. There was no tumor recurrence during a mean follow-up period of 5.6 years. Conclusions Mandibular ameloblastoma should be treated with segmental mandibulectomy (with a surgical margin of 2 cm) to reduce the risk of recurrence. Subsequent mandibular and adjacent soft tissue defects should be reconstructed immediately with a free fibula osteocutaneous flap.

PURPOSE : For the reconstruction of large bone defect after tumor resection, it is possible to reuse the bone involved by tumor with some treatment to it. Several bone-reusing methods have been reported such as autoclaving, low-heat treatment(pasteurization) and intraoperative radiotherapy. We have used extracorporeally radiated autogenous bone graft for reconstruction after tumor resection, and analyzed the periods for junctional union, functional results and complications to know the indications of this method. METHODS : From Dec. 1993 to Sept. 1995, nine patients had taken autogenous bone graft with extracorporeal irradiation. Eight cases were osteosarcoma and 1 giant cell tumor. The graft sites were 5 in femur, 3 proximal tibia and 1 femur and tibia. Stage 3 was 1 case(GCT), Stage IIB 3 and Stage IIIB 5. After wide resection, surrounding soft tissue and intramedullary and extramedullary portion of the tumor were removed. Radiation was done in 5000cGy to the resected bone. Ender nails and bone cement were inserted and filled into the medulla to prevent fracture. RESULTS : Average follow-up period was 12.3(4 to 21) months. Average junctional union period in simple X-ray was 6.5 months in 4 cases. Average functional score following Enneking's criteria was 19(12-27). Complications were as follows ; condylar fractures and femur neck fracture in 4 cases, subluxation of the knee joint 3 and infection 1. Although local recurrence was detected in 1 case, the site of recurrence was not in the radiated bone but surrounding soft tissue. At final follow-up, no recurrence was found in one case(GCT), CDF 2, AWD 2, DOD 3, and died of chemotherapy related sepsis 1. CONCLUSIONS : Extracorporeally radiated bone autograft is considered to be a method for reconstruction of the large bone defect made by tumor resection, especially in the reconstruction around the joint.
