Carotid body tumor is rare tumor in the neck. Among the pathologic ccnditions affecting paraganglionic tissue, the carotid body is most frequently involved. There are controversies in terms of natural history, biological behaviors, technique of excision. risks of the operation. Carotid angiography is the most valuable diagnostic aid and important for the planning of therapy. Defmite treatment of carotid body tumor is surgical exci.i!ion. Considerable degree of caution and vascular surgical armamentation are required because of its anatomical location and profuse vascularity. Surgical removal of this kind of paraganglioma must be predicated upon several factors such as tumor character, location. symptom, vascularity, and surgeon's ability.

The harvesting of costal cartilage for the total ear reconstruction elicits various functional and aesthetic problems such as pneumothorax, atelectasis, pain, scar and chest contour deformities. Although the costal cartilage has been the most popular autogenous tissue for the total ear reconstruction, the studies about problems of donor site after harvesting the costal cartilage were relatively rare. From March 1989 to October 1996, 153 cases of total ear reconstruction by the costal cartilage framework insertion were done in our hospital and 61 cases whose follow up were done over 6 months were analysed for donor site scar, contour deformity and rate of satisfaction. The optimal age of microtia reconstruction was considered as over the age of 8, because of the growth of the ear and the volume of costal cartilage. Through a small incision, 3 ~ 4 cm, on the contralateral chest, the 6th, 7th and 8th costal cartilage were harvested with the outer layer of perichondrium for survival of the costal cartilage framework, the inner layer of perichondrium was remained for the growth of costal cartilage. There were 4 cases of uneventful pleural perforation, and remained no problems on the patients. The state of chest donor site were analyzed on 61 patients by use of medical records, medical photos and interview with the patients. Mean length and width of chest scar were 5.2 cm and 2.3 mm 79% of patients classified as excellent or acceptable. Chest contour deformity was observed on 39% and 85% of patients were satisfied with the result of donor site.

Hemifacial microsomia is a descriptive term for the developmental anomaly affecting the tissues derived from 1st and 2nd branchial arches, expressed as asymmetric underdevelopement in facial bony skeleton. Conventional strategy of surgical correction for hemifacial microsornia consists of leveling though maxillary LeFort osteotomy and rotation, advancement and recession through bilateral sagittal split us osteotomy, which was reinforced by ancillary procedures such as mandibular augmentation with onlay bone graft, mandibular angle ostectomy, temporomandibular dibular joint (TMJ) reconstruction and malar reconstruction. But these like conventional methods for correction of hemifacial microsomia were emphasized on the correction of vertical asymmetry primarily, overlooked the asymmetry of horizontal plane, namely hypoplastic malar deformity. In general, correction of malar hypoplasia was achieved by rib or calvarial bone graft. These methods remain donor site deformity and the result can not be precisely predicted due to progressive resorption of bone. Moreover, the natural appearance of zygomatic complex could not be established by bone graft. Malar expansion by zygomatic osteotomy and spread-out technique was applied on correction for 34 case in total 65 cases of hemifacial microsomia from March 1991 to February 1996. We could get more natural appearance of malar complex and facial symmetry in the correction of hemifacial microsomia at one stage operation than conventional malar reconstruction methods.

Utilizing the lateral thigh flap as originally described by Se-Min Baek. in 1983, we have treated seven cases of reconstruction involving crushing injuries of the hand. This flap is derived from the third perforator of the deep femoral artery and accompanying wein as per Baek`s method. When a large skin flap was needed such as the case of crushing hand injuries, a lateral thigh flap was more useful than any other flap. From our experiences for reconstruction of crushing hand injuries, the following advantages of this flap are noted: 1. It is possible to obtain a large size of all skin flap. 2. It is relatively thin with a small amount of the subcutaneous fat. 3. The vascular pedicle is long (10㎝ or more), facilitating microvascular anastomosis. 4. The lateral thigh flap can be a sensory flap. 5. It can be accommodated easily to any operating position.

Malignant tumor of the head and neck can be treated by radical excision of the lesion. But the resultant facial deformity acts as a handicap in the patient's life. The quality of life is as important as the quantity. Therefore reconstruction of these patients is an important field in plastic surgery. We used 3 kinds of flap for reconstruction after maxillectomy. Two cases were late reconstruction with Rectus Abdominis myocutaneous free flap and parascapular free flap respectively. In remaining one case, immediate reconstruction was performed with rib bone graft and Latissimus Dorsi free flap. The results were satisfactory. But we found that ptosis of the flap is problem in all cases.

Nowadays the surgical attempts are on the increase in Korea to rejuvenate human aging faces. In 1979, at the Seventh International Congress of Plastic and Reconstructive Surgery in Rio de Janeiro, Paul Tessier described the subperiosteal frontal rhytidectomy. Since that historic point, surgical challenges to rejuvenate againg face by subperiosteal lifting of upper and middle face have been tried and developed. In 1984, Santana reaffirmed this technique by proving that a consequence of the aging process may be seen not only in the skin's cells and subcutaneous tissue but also in a series of structures that go from the bone(which ages not in form but in structure)to the periosteum and to the anatomical structures attached to it. In consideration of the concept of subperiosteal lifting and Korean's ethnic and social points of view, authors have operated on 18 female patients who mainly complaint of upper and middle facial aging appearances using the extensive subperiosteal dissection. The extensive subperiosteal face lift procedure was much ore effective, longer lasting and had more natural results. Complications were hematoma, hypoesthesia of scalp and focal hair loss but these wee completely recovered.

The double eyelid, which is a factor of beautiful eye, has been the interesting subject of the related study through anatomy. But in spite of generalized interest, there is scanty publications about the genetic aspect of the double eyelid. All of them are "single eyelid is dominant factor" by Fernandez in 1960, and "autosomal dominant inheritance with complete penetrance of single eyelid" by McCurdy in 1990. In this research, though I tried to verify of autosomal dominant inheritance of single or double eyelid in 2568 Korean of random sample, I found out that single or double eyelid is not inherited through autosomal dominant trait. As the result of analysis about parents type of eyelid, their pedigree, sex and age, I would like to suggest the hypothesis that the double eyelid have multifactorial inheritance pattern and its factors are double eyelid traits of parent, sex, age ethnic difference.

Various techniques such as bone graft, vascularized bone and implantation of synthetic material have been used to reconstruct the mandible but these techniques have their own limitations, that is, bony resorption, infection, donor site morbidity and exposure of implant. These limitations could be, however, overcome when the technique of bone lengthening by distraction osteogenesis, the process of generating new bone by gradual distraction. Bone lengthening by distraction osteogenesis has been performed to reconstruct the deficiency of long bones such as tibia since early twentieth century, and is now widely performed in the field of orthopedic surgery. But applying distraction osteogenesis in reconstructing the mandible has a short history. There are few reports describing the optimal rate of mandibular distraction and it remains also controversial whether the nerve injury occurs during distraction. The purpose of this study is to evaluate the process of new bone formation in the mandible and to exzamine the integrity of inferior alveolar nerve histologically when the distraction rate is 1.6mm per day. Six healthy 15 to 20Kg mongrel dogs served as the experimental animals. Left side periosteal preserving reversed L-shape corticotomy was performed from the antegonial notch, and an external lengthening device (Bonefix 200) was fixed parallel to the inferior border of the mandible. After 5 days of latent period, the mandible was lengthened 1.6mm per day(0.8mm in every 12 hrs) for 20 days and held in external fixation for 6 weeks after which all dogs were sacrificed. The specimens were evaluated anthropometrically, radiologically and histologically. Then the results were as follows; 1) The gain in length ranged from 18mm to 25mm(average 23mm). 2) The newly formed bone showed intramembranous ossification. 2 cases contained island of cartilage. 3) Most of nerve fibers in the elongated inferior alveolar nerve showed myelination and normal structure of axon. New bone formation at the distraction rate over 1 mm per day was favorable and most of the new bone was formed by intramembranous ossification, and also inferior alveolar nerve nearly maintained its integrity after distraction. However more detailed study is necessary to determine the ideal distraction rate and exacts ossification mechanism of the mandible.

백세민,김수신 大韓成形外科學會 1986 Archives of Plastic Surgery Vol.13 No.1

The concept of the myocutaneous flap has established various anatomic territories from which flaps may be elevated for reconstruction of defects in the area of head and neck. The trapezius muscle is a flat, triangular muscle, covering the back of the neck and shoulder. It arises from the medial one-third of the superior nuchal line of the occipital bone, the external occipital protuberance, the ligamentum nuchae, the spine of the seventh cervical and the spines of all the thracic vertebrae and the corresponding portion of the supraspinous ligament. The upper part of the muscle inserts to the lateral third of the clavicle; the middle part into the medial edge of the acromion and the upper border of the spine of the scapular; the lower part to terminate in a tubercle at the medial end of the spine of the scapular. The trapezius is supplied by the accessory nerve and also by branches from the third and fourth cervical nerves, which are probably sensory. The vascular supply comes from the transverse cercical artery and the occipital artery primarily. In an effort to define clinical usefulness of the trapezius myocutaneous flaps, this paper describes various myocutaneous flaps, incorporating various portions of the muscle and bone, and reports the clinical applications.

The present study was undertaken to determine if direct current(DC) electirical fields could improve survival rate of random pattern skin flap in the rat. 20 Sparque- Dawley rats were divided into two groups and caudally based 2cm width and 8cm length random pattern flaps were elevated in all rats. Electrical fields of 9mA were introduced by 1.5V disk button battery. Electrical field was applied for 5days to the stimulation group(B). DC electrical fields shows the enhancement of flap survival by increasing the rate to 33.5%(p<0.01). The enhancement of skin flap survival by application of direct current electrical field has possibility for cover the large skin defect.
