Skull base surgery has developed through the evolution of imaging, anatomic research, surgical approach and reconstructive techniques. The basic disciplines of approaching skull base lesions are provide direct vision, minimizing brain retraction, excellent exposure and minimal blood loss. The focus of this report is to review the advantages of skull base approach in our cases and suggest some indications. We experienced 20 cases of skull base surgery by a team approach consisting of a neurosurgeon and plastic surgeon. The surgical approach were supraorbital osteotomy(5 case), orbitozygomatic osteotomy(8 case), orbitozygomaticoglenoid osteotomy(5 case) and orbitozygomaticoglenoidocondylar osteotomy(2 case). In our experiene, these approaches provided excellent exposure of the lesion, direct access to lesions and minimal brain retraction thereby better outcome.

Exophthalmos may be caused by thyrotoxic ophthalmopathy, intraorbital tumors, or arteriovenous malformation. Exophthalmos caused by a chronic epidural hematoma is rare and to our knowledge there is no previous report of a chronic epidural hematoma causing exophthalmos. This case shows unilateral exophthalmos related not to acute injury but to chronic epidural hematoma and granulation tissue in-growth through the orbital roof fracture caused by secondary trauma. Operative correction was performed by utilizing a frontal craniotomy. We removed the chronic epidural hematoma. After removal of the left orbital roof, we removed the hematoma and the granulation tissue. The bony defect of the orbital roof was reconstructed by using a split calvarial bone graft. The result of the correction was satisfactory.

조을제,탁관철,유원민,박병윤,황규석 大韓成形外科學會 1998 Archives of Plastic Surgery Vol.25 No.4

Sacral pressure sores have been treated by a variety of surgical methods. complete treatment needs wide excision and coverage with healthy tissue which has constant and sufficient blood supply. Use of gluteus maximus muscle flap with or without overlying skin is a revolutionary method because of the reliability of blood supply. However, it is technically a little bit complicated, and future reconstruction for recurrent decubitus is especially limited in paraplegic patients. The development of gluteal perforator-based flap with para-sacral perforator introduce a new treatment modality for the sacral pressure sores. Total 10 cases of sacral pressure sores were treated with gluteal perforator-based flap. There were minimal postoperative complications except wound dehiscence in one case. This flap has a many advantage of no transection or sacrifice of the gluteus maximus muscle, elevation time for the flap is short, reliable blood flow of the perforator, large rotation arc and no post-operative hindrance to walking in patients who are not paraplegic. The disadvantages of this perforator-based flaps are the anatomical variation in the location of perforators and the need for technically careful dissection.

Since Zeller first introduced the local flap transposition in the correction of a syndactyly in 1810, an evolution of improvements has taken place during the last 180 years. The principles of syndactyly correction are well established at the present time. Current principles of syndactyly correction are: 1) Creation of dorsal and/or palmar flap to create and line the commissure. 2) Zig-zag incisions to lessen the contracture. 3) Skin grafts to cover raw areas Numerous operative techniques have been devised on the basis of the above pronciples. the authors also have modified the current methods of syndactyly correction ;truncated rectangular flaps were elevated from both the palmar and dorsal sides. The free margins of the elevated flaps were approximated at the base of the newly formed interdigital space. Skin incisions were designed in a zig-zag pattern. Raw surgaces were confined near the base of digits as much as possible and were covered with full thickness skin harvested from the inguinal area. We adopted the above method in 6 cases of syndactylty of the fingers and 2 long term follow-up indicates that gratifying functional and aesthetic results could be achieved without recurrences of the deformity and disabling contractures of the interdigital space.

조을제,전재용,장석주 大韓成形外科學會 1994 Archives of Plastic Surgery Vol.21 No.2

The facial bone is composed of multiple protuberance and arched structures which are easily exposed to trauma. In displaced facial bone fracture combining facial deformity, and functional disturbance, it is necessary to correct the deformity by open reduction and internal fixation. The purpose of the treatment of facial bone fracture is accurate anatomic reduction and fixation. The authors reviewed 42 facial bone fractures. of 39 patients who were treated with microplates and screws. Among the facial bone fractures, zygoma was most frequently involved and maxilla was treated only in one case. In the mandibular fracture treated with microplates, parasymphyseal fracture was commonest. The hematoma developed in one case on the subcilliary incision site was treated with needle aspiration. A comparison was done between microplate fixation and other classical fixation methods in the treatment of facial bone fractures.

Many investigators have reported that collagen gel contraction reflects the mechanism of wound contraction. In 1995, Tsai et al. reported that hypertrophic scar-derived fibroblasts in a connective tissue model possessed the greatest contraction potency when compared with those of normal skin and normal oral mucosa-derived CTMs. In this study, we studied the effect of collagen gel contraction by growth factors such as epidermal growth factor, platelet-derived growth factor, transforming growth factor-β1, and transforming growth factor-β3, Skin fibroblasts used in this study were obtained from the explant of rat skin culture. Fibroblasts were cultured in Dulbecco's modified Eagle's medium containing 10% fetal bovine serum. Growth factors were added per FPCL in the desired concentrations and we measured the collagen gel diameters in growth factor-treated FPCL on day 1,2,3, and 4 respectively after starting incubation. We examined the effects of EGF, PDGF, TGF-β₁, TGF-β₃ and the effects of combinations of TGF-β₁+ EGF, TGF-β₁+ PDGF, and TGF-β₁+ TGF-β₃ to contract a collagen gel. EGF has little influence on collagen gel contraction. TGF-β₁ and TGF-β₃ increase the collagen contraction. TGF-β₁ enhanced the contractility of collagen gel according to the concentrations. While TGF-β₃ alone had stimulatory contraction effects at low dose, high doses of TGF-β₃ decreased the potency of collagen gel contraction. A combination of TGF-β₁ and EGF minimally decrease TGF-β₁ activity. A combination of TGF-β₁and PDGF had an effect similar to TGF-β₁ activity. A combination of TGF-β₁ and TGF-β₃ decreased TGF-β₁ activity. According to reports that FPCL contraction is equivalent to the process of wound contraction, growth factors which enhance gel contraction may be related to wound contraction and wound healing. TGF-β₁ is reported to enhance scar formation in fetal wound. EGF accelerates wound healing and inhibits the promotion of hypertrophic scar formation. Compared to the effect of collagen gel contraction in this study, the combination of TGF-β₁ and TGF-β₃ that inhibited the promotion of collagen gel contraction are thought to diminish the formation of scar tissue. As well, EGF that has not enhanced collagen gel contraction is thought to diminish the production of scar tissue. We will study the interactive effects of TGF-β₃, EGF and TGF-β₁ on the contraction of collagen gels in the future.

Reconstruction of soft tissue defects with exposure of bone or tendons on the hands can be a difficult problem. Local subcutaneous tissue flaps with immediate skin graft were successfully used to reconstruct the soft tissue defect of hand in 4 cases of 3 patients. All flaps survive completley with no major problems. Among various technique the benefits of this flap are that it is and easy and rapid one-Stage procedure, it requires limited immobilization of the involved joint, it leaves an inconspicuous donor site scar and it preserving the shape of the limb. Thus this technique is very useful inrepairing soft tissue defect in the hand and can replace the classical fasciocutaneous flap, local muscle flap and even free flap.

조을제,박병윤,최중언,유재덕 大韓成形外科學會 1992 Archives of Plastic Surgery Vol.19 No.5

Craniosynostosis is the term that designates premature fusion of one or more sutures in either cranial vault or cranial base. Since several case reports of strip craniectomy had been recorded in the literature before the turn of the century, an evolution of improvements in the correction of the craniosynostosis has taken place. The widespread protocol is established in the present time. In isolated synostoses, strip craniectomy has been replaced in recent years by fromtal bone advancement and cranial vault remodeling. The procedures are usually performed at 6 months of age. We reviewed 17 patients with isolated craniosynostosis who had undergone surgical treatments and report the surgical methods, the timing of surgery, the operation time, the amount of blood transfusion and complications with review of the literature. In scaphocephaly, we performed cranial vault remodeling. In other cases, bilateral supraorbital band advancement and forehead remodeling were performed. We followed each patient for 3 years in average (2 months-6 years) and the result was analized according to the type of disease. We drew the following conclusions: 1) Early surgery is important to ensure good prognosis; surgery should be undertaken within 4 months of age regardless of the types of anomaly. 2) Many patients accompanied CNS problems and the early release of cranial base did not alter the course of the already occurred CNS problems. 3) Among the types of craniosynostosis, the plagiocephaly did not show any CNS problem; more-over, operations of the patients showed the best results.
