Coverage of Donor Site Defect of Radial Forearm Free Flap by using Terudermis(R)

Split-thickness skin grafting is commonly used to cover donor site defect of radial forearm free flap. One of disadvantages in this method is contour reflection of underlying structures (tendons and muscles) with irregularity which was caused by incomplete soft tissue replacement, and we called it 'silhouette phenomenon'. To promote soft tissue replacement, we have used Terudermis(R) (atelocollagen). In 10 cases of radial forearm free flap surgery of 10 patients, Terudermis(R) was applied on flap donor site just after flap surgery, followed by split-thickness skin grafting for resurfacing after 2 weeks. In all cases, Terudermis(R) and skin graft were taken well with no complications such as skin necrosis and loss. We successfully overcame silhouette phenomenon in all cases in the follow-up period of mean 8 months. Terudermis(R) , as a tissue-restoring biomaterial, is expected to be easily used for coverage of donor site defect of radial forearm free flap.

Modification of Le Fort III Osteotomy and Fronto-orbital Advancement for the Correction of Crouzon's Disease

In 1912, Crouzon reported one of craniofacial dysostosis, which was inherited as an autosomal dominant trait and characterized by craniosynostosis, midface hypoplasia, and exorbitism. In 1950, the first midface advancement was performed by means of a total facial osteotomy by Sir Harold Gillies. In 1967, Tessier accomplished complete craniofacial dysjunction by performing Le Fort III-Tessier I osteotomy on the basis of Le Fort III fracture and laid the foundation for modern craniofacial surgery. Variable combinations of the surgeries and osteotomies are performed considering functional disabilities as well as patient's age, general condition, and aesthetic problems. The nineteen-year-old female patient complained of frog-like face and showed severe exorbitism and midface hypoplasia, while the occlusion, being relatively normal. We applied modified Le Fort III osteotomy and fronto- orbital advancement. Over the follow-up period of six months, her previous normal occlusion was preserved and the exorbitism and midface deformity largely improved aesthetically.

Orbital Volume Change Measured by Computed Tomography in Blow Out Fracture

Enophthalmos is a common result of blow out fracture of the orbit. Prior to CT volume analysis no reliable measurement of the degree of bony and soft tissue deformity was available to identify patients who would develop enophthalmos. Evaluation of orbital volume expansion and volume expansion percentage were performed in 23 patients with blow out fracture, after 1-4 days of injury. All studies were performed on a CT (Somatom Plus, Germany, Siemens), using transaxial scan technique(140 kVp, 206 mA, 3 mm contiguous sections). The radiological boundaries of the orbit were defined anteriorly by a line mrrecting the anterior surface of the zygomaticofrontal process to the nasomaxillary suture and posteriorly to the optic foramen. The Hounsfield Unit(HU) ranges were -100 to 0 and 0 to +100. It is difficult to distinguish blood from fat in the orbital volume measurement. We used three methods to obtain more accurate orbital volume. First, The concave margin or the air meniscus surface area is blood and the convex margin area is fat. Second, It can be distingushed blood from fat by Hounsfield Unit of specific area pixel. Third, The homogenous area is blood and inhomogenous area is fat or mixture of fat and blood. The patients(> or =13% orbital volume expansion) are managed surgically. 15 patients were classified in operative group and 8 patients were in conservative treatment group. The volume expansion percentage is 12.7% to 28.8% in operative group and 4.2% to 11.2% in conservative group. There was no enophthamos in each groups after 3 months of operation and injury. CT measurements of orbital volume expansion and volume expansion percentage can predict the final degree of the late enophthalmos and may facilitate the planning of surgical intervention. To obtain more accurate prediction of enophthalmos, we consider not olny volume expansion but also volume expansion percentage, because everyone doesn't have the same normal orbital volume.

Huge Chondroid Syringoma of the Forehead: A case report

Chondroid syringoma also known as cutaneous mixed tumor of salivary gland type, is a relatively uncommon adnexal tumor of sweat gland origin. Most of these tumors are benign, although occasional malignant variants have been documented. Commonly, these tumors occur in the head and neck region but any part of the body may be affected. Their usual size is between 0.5-3.0cm. We treated a 47-years-old man was seen for tumor first noticed about 17 years ago on the forehead. This mass had been increasing in size slowly, An 8 x 8 x 9 cm size mass with surrounding subcutaneous tissue and overlying skin was excised from frontalis muscle fascia. On frozen biopsy, there was no malignant change. The wound was covered by skin graft. Microscopically, the mass is composed of glands or tubules, adipose tissue and hyalinized or chondromyxoid stroma(PAS:- , Alcian blue: +). Several areas show adenoic cystic carcinoma pattern, suspicous for early malignant change. No evidence of local recurrence has surfaced after 6 months of operation.

A Study of Partial Excision and Suvdermal Exicision in Surgical Treatment of Axillary Osmidrosis

There are 3 basic methods for surgical treatment of axillary osmidrosis; 1) method that removes only subcutaneous cellular tissue without removing skin 2) method that removes skin and subcutaneous cellular tissue en bloc, and 3) method that partially removes skin and subcutaneous cellular en bloc as well as removing the subcutaneous cellular tissue of the adjacent region. We studied the results of partial removal of the skin and subcutaneous cellular tissue en bloc, as well as the removal of subcutaneous cellular tissue of the adjacent region to compare the results of the bipedicled flap with the graft conversion method. There was no difference between two methods in results and complication rates. There are 3 advantage to this procedure. First, about 70-80% of apocrine glands were centrally distributed among the axillary hairbearing region therefore, resection of the central portion of axillary hair distribution area is important for good result. Second, the preservation of the subdermal plexus with careful excision of adjacent underlying subcutaneous tissue under the aid of the magnifying surgical loupe, is important for good wound healing. Third, the central excision of the axillary hair distribution area provides good exploration for undermining and defatting of the undersurface of the adjacent area, therefore it tooks a shorter operation time.

A comparisin of the Operative Results and Costs Between Interosseous Wiring and Miniplate Fixation in Open Reduction of Mandible Fracture

Mandible fractures have recently been managed by rigid internal fixation with miniplate and screws more often than by traditional interosseous wiring methods. The purpose of this paper was to compare traditional interosseous wiring with miniplate fixation in open reduction of mandible fracture, especKweonially in operative results and costs. From June of 1989 to June of 1998, there were 142 patients, admitted to the department of Plastic and Reconstructive Surgery, Chun-Cheon Sacred Heart Hospital, Hallym University. Of those, 101 patients were managed by open reduction, and among them, 83 patients were treated with miniplate fixation, but 18 patients had recently been treated with interosseous wiring methods. No significant difference was noted between the two groups in terms of complications, but the overall cost of miniplate and screws was higher than interosseous wiring, while the mean operative time was longer in the group treated with miniplate fiation. The authors recommend interosseous wiring technique for patients with mandible fractures requiring open reduction and fixation, except for absolute indications of rigid internal fixation.

Reconstruction of the alveolar cleft with gingivo-vestibular-mucoperiosteal flap

The maxillary alveolar ridge separates the palate from the lip and clefts of the primary palate have a cleft of the alveolus as well. In the most common clefts of the primary palate, the alveolar portion of the cleft is located between the lateral incisor, if present, and the canine. The cleft may also pass between the central incisor and the lateral incisor, rarer forms of clefts may pass between the central incisor or more distally on the maxillary arch. There are still considerable differences of opinion as to the optimal time for closure of alveolar defects, with or without concomitant bone grafting. But the preferred time for the operation with bone graft is between age 9 and 11 before the canine teeth have fully erupted. As an alternative to primary bone grafting, Skoog developed the periosteoplasty, or "boneless bone graft" technique, in which periosteal continuity was established between maxillary segments by the transfer of local periosteal flaps from the anterior maxillary wall. this procedure, which takes advantage of the propensity of periosteum to form bone in young children, leads to the formation of new bone within the alveolar cleft in spite of the fact that no bone graft is used.This study attempts to defin the effectiveness of early alveolar cleft repair with gingivo-vestibular-mucoperiosteal flap.The results in 6 unilateral alveolar clefts and 1 bilateral alveolar cleft, which is corrected early by gingivo-vestibular-mucoperiosteal flap, have been satisfactory alveolar arch continuity and alveolar bone formation with tooth eruption.

Clinical Experience of Gentian Violet Dressing for Local Treatment of Wound Infection with MRSA / 병원감염관리

BACKGROUND: Methicillin-resistant Staphylococcus aureus (MRSA) is hardly controllable organism among the pathogen of nosocomial infection, because it is resistant to most antibiotics except vancomycin and local treatment with most antiseptics are not effective to eradicate MRSA from the infected wounds. There is increasing fear that MRSA infection can be spread widely in the hospitals. The effectiveness of Gentian Violet against MRSA was reported by Saji et al in 1992 for the first time. We tried Gentian Violet dressing on MRSA infected wounds to evaluate whether at not the Gentian Violet is effective to eradicate 11RSA which existed in the open wound. METHODS: 24 patients were treated by wet dressing with 0.1%Gentian Violet soaked gauze twice daily. They included 10 cases of sacral and trochanteric pressure sore, 6 cases of postoperative wound infectious, 3 cases of posttraumatic skin defects, 2 cases of DM foot, 1 case of post infectious skin defect and 2 cases of electrical burn, The wound culture was evaluated for elimination of MRSA infection twice weekly. RESULTS: The clinical results revealed that MRSA was not detected in all cases within 34days (average 13.5 days) after topical administration 0.1% Gentian Violet. CONCLUSION: There is no evidence of tissue irritation with Gentian Violet dressing on open wound or wound margin. After negative conversion of MRSA with Gentian Violet dressing, gram (-) organism was isolated in a half of the cases. 0.1% Gentian Violet topical administration is a useful treatment method of wound infection with MRSA.
