유리전박피판술의 응용과 유리전박이중피판술의 고안

윤근철 충남대학교 의과대학 지역사회의학연구소 1987 충남의대잡지 Vol.14 No.2

Since the opening era of reconstructive microsugery, many free flap donor sites have been investigated and used clinically. Up to date over-sixty free flaps have been registered in our surgical memorandum. Among them several free flaps deserve to be admired for their superior clinical adoptability to the other free flaps. The forearm free flap, which is also called "Chinese free flap" because it was introduced to us by Chinese plastic surgeons, is used and admired world-widely recently for it's convenience of performance and acceptable clinical results. Author performed the forearm free flap in reconstructing one case of compound facial defect and three cases of pharyngoesophagus ablation. Notably the auther duplicated the flap for inner lining of nose and release of stenotic permenant tracheal opening. Four cases of forearm free flap and method of duplicating flap are reviewed and discussed with literatures.

유리피판을 이용한 두경부재건술에 관한 임상적 고찰

윤근철 충남대학교 의과대학 지역사회의학연구소 1988 충남의대잡지 Vol.15 No.2

The method of reconstruction has been known to take large part in the quality of treatment of head and neck malignancies. Every effort has been made by many reconstructive surgeons to improve postoperative life quality of the patients. Among them, free flap by microvascular transfer techniqueare relatively new but much contributory method. We have experienced 8 free flap cases for reconstruction of head and neck cancer patient since 1987. They are 5 cases of forearm free flaps for cervical pharyngoesophagus reconstruction and 3 cases of scapular steocutaneous free flaps for lower jaw reconstruction. Although the quantity of our experience is not large, we discuss its advantages, disadvantages for further refinement.

"후천성안면열-Noma 후유증"의 치험례

신영진,윤근철 大韓成形外科學會 1989 Archives of Plastic Surgery Vol.16 No.5

The authors experienced reconstruction of a complex adult facial deformity extending from right side of nose to right anterior part of the maxilla owing to tissue necrosis from small pox complication in a neonate. Because the event ocurred in the very early period of life, the secondary deviation of the facial structures through growth was an additional problem besides simple tissue defects. As it seemed that was vary like the features of congenital facial cleft due to the error in viviparity, we dared to name deformity acquired facial cleft. Etiologically the deformity can be classified as a sequale of noma which defines a mixed aggressive infection of the facial tissue in chronically mal nourished children during or soon after an acute debilitation illness. Because the socioeconomic condition of our country has improved so much, active noma cases are rare nowadays. So we are presenting a case of acquired facial cleft due to noma sequale for following reasons in summary. 1. Noma survivor is quite rare nowadays and there is rare clinical report of reconstructing that deformity in this country. 2. Because the deformity or defects of this case involves multiple facial units, we consider the experience of reconstructing this case is invaluable.

백계 족지에서의 Bunnel과 Bevel건 봉합술 후의 유착 및 활주기능 비교관찰

Restoration of function after tenorraphy in digital sheath has been most baffling problem in hand surgery and adhesion formation has been thought to be a pre-requisite for tendon healing. But recent work demonstrated that a tendon is a metabolically active tissue and also has intrinsic mechanism of repair. There are many methods of tenorrhaphy based on this fact. Among them a methodintroduced by Hilton Becker has a sufficiently strong junction which enables immediate active mobilization without strangulation of blood supply. This time, we observed a difference in gliding function following Becker type and classical Bunnel tenorraphy using chicken toes.

In Craniofacial reconstruction, autogenous grafting is not always welcomed in clinical cases because of the volume limitation and donor site morbidity. Therefore research for suitable bone graft substitute has continued. Lyophilized bank cartilage(LC) was introduced by Dr. Sailer with superior clinical results for facial contour correction. However, there has been scanty literature regarding the healing process of LC. We assumed that the healing process of LC might be different from that of fresh cartilage allograft because of the lyophilization process. We prepared the rabbet rib cartilage by defatting, lyophilization and gas sterilization and this LC(rabbit lyophilized bank cartilage) was stored at room temperature and hydrated for 24 hours in antibiotic solution just before use. 15 rabbits underwent subperiosteal implantation of banked LC, autogenous rib cartilage, fresh frozen cartilage allograft and autogenous rib bone on the snout with microscrew fixation. They were sacrificed after 1 week, 4 weeks and 16 weeks. the specimens were decalcified and histology was reviewed. We compared the histology of healing for 16 weeks and found that the potential for bone for mation with moderate maintenance of shape is unique In LC healing process.

자가이개연골이식을 이용한 상안검 퇴축의 교정

The retraction of the upper eyelid occurs most frequently as one of the ocular manifestations of thyroid disease, also occurs iatrogenically after eyelid or orbital surgery. With varying degrees, excessive corneal exposure leads to discomfort, epiphora and decreased visual acuity. Moreover increased showing of sclera above upper corneal limbus is considered one of the cosmetic defects. The difficulties in surgical correction consist of anatomic delicacy of the eyelid and unpredictability of levator-Muller muscle manipulation and healing of grafted materials. To avoid these difficulties, we used bihalved autograft of antihelical cartilage as a spacer to keep the recessed levator from reattaching to the upper border of the tarsus, in one case of thyoid ophthalmopathy and in one case of repeated blepharoplasty. It is autogenous, sturdy, thin material and harvesting is easy. The result was satisfactory without undercorrection nor overcorrection.

하악절골술에서의 융비술의 역할

김준성,윤근철 大韓成形外科學會 1995 Archives of Plastic Surgery Vol.22 No.2

Augmentation rhinoplasty is by far the most frequent aesthetic procedure in oriental faces. The flat and broad dorsum of nose doesn't go well with the modern standard of beauty. In the meanwhile, the facial bone osteotomies are about to gain popularity in our society. The aesthetic relation between nose and jaw cannot be ignored. An example of interaction between reduction rhinoplasty and advancement genioplasty in western literature is quiet well known. Herein we can postulate the positive effect of augmentation rhinoplasty to mandibular setback and advancement genioplasty. Augmentation rhinoplasty per se has an effect of advancing soft tissue nasion and nasal tip in the facial profile. These changes have an indirect camouflaging effect on mandibular prognathism. Theoretically because the advanced nasion has an effect of diminution of SNB angle and nasal tip projection and advanced chin have an effect of moving Ricketts' esthetic line anteriorly. In this article we present the examples of augmentation rhinoplasties carried out with mandibular surgery to enhance the overall aesthetic result. The technical detail, an aesthetic interaction with mandibular changes and advantages are discussed.

Titanium micro-mesh를 이용한 광범위한 안와상벽결손의 재건

최해천,윤근철 大韓成形外科學會 1994 Archives of Plastic Surgery Vol.21 No.4

In the reconstruction of the massive orbital wall defect, the accuracy in three dimensional anatomic restoration is a paramount importance to prevent enophthalmos and dystopia. Although autogenous bone graft is theoretically ideal, its later resorption and difficulties in shaping make the goal seldom accompanished. Inorganic implants are not welcomed for high rate of infection. Meanwhile, the advent of titanium implants afforded us more dexterity in facial bone fixation. The titanium, micro-mesh was introduced and used with bone grafts for massive orbital floor reconstruction to ensure perfect restoration of the orbital volume and the position of eyeball. Likewise the floor, reconstruction of the orbital roof defect is not easy because of its complex domed contour especially when the defect is so massive as adjacent frontal bone, lateral and medial orbital wall are included. We experienced two cases of successful reconstruction of the massive orbital roof defect with titanium micro mesh. The meshes were prefabricated on a dry skull and used as a carrier for rib bone graft or a support for fractured bone fragments.

Latissimus Dorsi Myocutaneous Island Flap을 이용한 上腕의 Dermatofibrosarcoma Protuberans 治驗例

민경원,김진환,윤근철 대한성형외과학회 1981 Archives of Plastic Surgery Vol.8 No.1

The dermatofibrosarcoma protuberans is one of rare neoplasms which is characterized by bulky, protuberant tumor mass that looks like infected keloids. Histologically, it displays areas with uniform, closely aggregated spindle-shaped cells arranged in a storiform pattern. We have presented a case of Dermatofibrosacoma protuberans which was widely excised and the defect was covered with Latissimus dorsi myocutaneous flap and the donor defect was covered with mesh graft. The result was acceptable.
