PURPOSE: In the correction of cleft lip, there have been various methods to minimize recurrence of the nasal deformity after primary nasal surgery. After cheiloplasty and primary nasal surgery, we tried to elongate the columella of the cleft side, to stretch the vestibular lining of cleft side, and to elevate the alar cartilage of the cleft side with a molding prong. METHODS: We had fifteen cleft lip patients; 12 unilateral cases(6.3-8.2 months), and 3 bilateral cases(3 -7.5 months). Immediately after primary repair of the cleft lip, the toboggan shaped molding prong was located to deep inside of vestibular web of the cleft side. It was persistently suspended by a silicone tube which was connected to the prong and the frontal scalp. The results were analyzed with Photoshop(R) photogrammetrically for 6-48 months with on average of 20.6 months. We measured the proportion index of columellar length-interalar distance for three times(preoperation, immediate postoperation, and postoperation) on the nasal base views. RESULTS: In unilateral, the index had a significant increase statistically between preoperation(10.73) and immediate postoperation(23.96). It is supposed that columellar length was reconstructed to 105.80% of normal side. But, it was decreased to maintain 87.7% of normal side in postoperation(20.54). The results were similar in bilateral. The linear scars by suture penetrating nose skin were not discernable. CONCLUSION: In summary, placement of the molding prong could elongate the reconstructed columella with some relapse postoperatively.

Drug-induced thrombocytopenia and purpura have boon developed by many various agents. Rifampin and Pyrazinamide have been known as bactericidal antituberculous drugs, but, the above side effects have been a problem. Especially, hematologic side effects art fatal to patients occasionally. Rifampin-induced thrombocytopenia and purpura have been well known, also, pyrazinamide-induced thrombocytopenia have been reported. A new quilonone agent Ciprofloxacin, has been commonly used in clinics now, but it's side effects are not known well. So, we report a case of a 23-year-old female with thrombocytopenia and purpura after taking Rifampin, Pyrazinamide, and Ciprofloxacin as antituberculous agents.

STATEMENT OF PROBLEM: There have been previous studies about considerable variations in machining accuracy and consistency in the implant-abutment-screw interfaces. PURPOSE: The purpose of this study was to evaluate the machining accuracy and consistency of implant/abutment/screw combinations on two randomly selected implants from each of four manufactures. MATERIAL AND METHODS: In this study, screws were respectively used to secure a cemented abutment to a hexlock implant fixture; teflon coated titanium alloy screw(Torq-Tite) and titanium alloy screw in Steri-Oss system, gold-plated gold-palladium alloy screw(Gold-Tite) and titanium alloy screw in 3i system, gold screw and titanium screw in AVANA Dental Implant system, and titanium screws in Paragon System. The implants were perpendicularly mounted in polymethyl methacrylate autopolymerizing acrylic resin block(Orthodontic resin, Densply International Inc. USA) by use of dental surveyer. Each abutment screw was secured to the implant with recommended torque value using a digital torque controller. Each screw was again tightened after 10minutes. All samples were cross sectioned with grinder-polisher unit(Omnilap 2000 SBT Inc) after embeded in liquid unsaturated polyester (Epovia, Cray Valley Inc). RESULTS: There were the largest gaps in the neck areas of screws in hexagonal extension implants which were examined in this study. The leading edge of the abutment screw thread (superior surface) was in contact with the implant body thread, and the majority of the contacting surfaces were localized to the middle portion of the mating threads. Considerable variation in the contacting surfaces was noted in the samples evaluated. Amounts of contact in the abutment screw thread were larger for assemblies with Gold-Tite screw, gold alloy screw, Torq-Tite screw than those with titanium screws. The findings of intimate contact between the screw and screw seat were seen in all samples, regardless of manufacturers. However, microgap between the head and lateral neck surface of the screw and the abutment could be dectected in all samples. The findings of intimate contact between the platform of the implant and the bottom of the abutment were consistent in all samples, regardless of manufacturers. However, microgaps between the lateral surface of external hex of the fixture and the abutment could be dectected in all samples. CONCLUSION: Considerable variations in machining accuracy and consistency were noted in the samples and the implant-abutment-screw interfaces were incomplete. From the results of this study, further development of the system will be required, including improvements in pattern design.

PURPOSE: Hook nail deformity is caused by inadequately supported nail bed due to loss of distal phalanx or lack of soft tissue, resulting in a claw-like nail form. A composite graft from the foot bencath the nail bed gives adequate restoration of tip pulp. METHODS: From September of 1999 to March of 2004, six patients were treated for hook nail deformity and monitored for long term follow up. Donor sites were the lateral side of the big toe or instep area of the foot. We examined cosmetic appearance and nail hooking and sensory test. The curved nail was measured by the picture of before and after surgery. RESULTS: In all cases, composite grafts were well taken, and hook nail deformities were corrected. The curved nail of the 4 patients after surgery were improved to average 28.7 degrees from average 55.2 degrees before surgery. The static two point discrimination average was 6.5mm and the moving two point discrimination average was 5.8mm in the sensory test. CONCLUSION: Composite graft taken from foot supports the nail bed with the tissue closely resembling the fingertip tissue, making it possible for anatomical and histological rebuilding of fingertip.

PURPOSE: Nasal bone fractures are often classified as minor injury. However, the incidence of posttraumatic nasal deformity remains alarmingly high. It is because of unnoticed septal fracture. This study was conducted to determine the necessity of septoplasty for patients with nasal bone fracture accompanying grade I septal fractures. METHODS: Among 105 patients with nasal bone fractures, 52 who had grade I septal fracture were diagnosed based on physical examination and computed tomography. Patients' age ranged from 14 to 65 years (mean 29.25 years), and 35 were male and 17 female. Patients were divided into 2 groups according to surgical treatment METHODS: patients who underwent closed reduction only (group 1, n=28) and those who underwent simultaneous closed reduction and septoplasty (group 2, n=24). The treatment outcomes were evaluated by comparing changes in nasal airway volume measured by acoustic rhinometry before the surgery, 3 months and 6 months after the surgery according to the timing of surgical repair and surgical treatment methods. RESULTS: Nasal airway volume increased after the surgery by 17.8% in 3 months after the surgery, 25.2% in 6 months in group 1 and by 22.7% in 3 months, 35.8% in 6 months in group 2. The increase in airway volume after the surgery by 26.3% in 3 months after the surgery, 34.2% in 6 months after the surgery in operation within 1 week after trauma and by 12.1% in 3 months, 22.2% in 6 months after the operation later 1 week after trauma. The difference was statistically significant. Three patients in group 1 complained of intermittent nasal obstruction, two of whom showed a decrease in nasal airway volume by acoustic rhinometry. CONCLUSION: Most patients with nasal bone fractures accompanying grade I septal fractures have been treated with closed reduction in clinical settings. However, the results of this study suggest that septoplasty be performed after a correct diagnosis of septal fracture is made through comprehensive physical examination and computed tomography. Septoplasty is important to obtain more favorable outcomes and reduce complication.

PURPOSE: In the partial thickness burn management, despite of several advantages, the use of human amniotic membrane has been limited. The authors applied dried bovine amniotic membrane(DBAM) to overcome disadvantages of amniotic membrane for partial thickness burn and to compare the effectiveness of cultured allogenic keratinocytes(CAK) that have been recently used for the management of burn. METHODS: From August 2007 to May 2008, 16 patients with partial thickness burn were assigned to this study. The ages ranged from 12 to 59, with the average of 38. Either DBAM or CAK were applied, and the secondary dressing was removed on the following day. To compare treatment effect, time for epithelization, Vancouver scar scale and chromameteric results were evaluated. RESULTS: The time for epithelization was 10.1 days and 9.1 days in DBAM and CAK, respectively, which are shorter than the previous 2-3 weeks. At the follow up Vancouver scar scale was 2.8 in DBAM and 3.0 points in CAK, both of which showed good results. The results of chromameter showed that the L*, a*, and b* values of the area applied DBAM were 60.1, 13.6, and 13.3, respectively, and the values of the area applied CAK were 60.1, 12.4, and 12.4, respectively. It was found that the skin color of the healed area after burn was darker, the redness was higher, and the yellowness was lower. After dressing, no significant side effects were observed, and in the cases of applying CAK, it was inconvenient as the moving area had to be fixed. CONCLUSION: As CAK, DBAM has several advantages such as the shortening of the epithelization period, reduction of scar and pigmentation, and convenient application, etc., it is an effective method for the partial thickness burn management.

A total of 21 patients were operated. Via a columellar labial incision, the upper lateral cartilages were separated from the septum. A submucous resection of the septal cartilage was carried out. After rasping the convex lateral nasal wall of the unaffected side, a low-to-low lateral nasal osteotomy was conducted. Along the deviated dorsal line at the bony vault passing the submucous tunnel, a paramedian nasal osteotomy was performed. The convex side of the nasal bone flap was contoured by rasping. The convex side of the "T"-shaped dorsal septum was trimmed. A total direct septal extension graft of the septal cartilage was done and the alar cartilages were suspended to it. The postoperative results were evaluated by photogrammetric analysis processed by a "neon glow" filter in Adobe Photoshop. The distance from the nasal midline to the most deflective point at 5 levels was measured, and the proportion indices were obtained in regard to intercanthal distance. The results revealed improvement in all levels (p < 0.05), although not perfect. In summary, this technique can result in a clinically good-looking in spite of a slight deflection that still exists.

PURPOSE: Complete septal extension grafts have been widely used in rhinoplasty for effective projection of the short retruded columella in Asian patients. Autologous septal cartilages and porous high-density polyethylene sheets are frequently used as septal extension grafts. This study was conducted to compare the postoperative results of porous polyethylene sheets and septal cartilages used for correction of unilateral cleft lip nasal deformities by using photogrammetric analysis. METHODS: This study investigated a total of 49 patients with cleft lip nasal deformities who underwent corrective surgery, and were followed up for at least 6 months. Septal cartilages were used in 39 patients, and porous polyethylene sheets were used in 10 patients. In all patients, through the open rhinoplasty, complete septal extension grafts were sutured to the caudal margin of the septal cartilage, and the alar cartilage was sutured with suspension. The cleft side alar cartilage was overcorrected by approximately 3 - 5 mm. Postoperative outcomes were evaluated by using photogrammetric analysis. Five indices and 4 angles were measured on their photographs taken before and after the surgery. In patients with unilateral cleft lip nasal deformities, symmetry was also evaluated by means of columellar length index. RESULTS: The postoperative values obtained in photogrammetric analysis showed improvements in comparison with the preoperative ones. The polyethylene group produced more improved outcomes than the septal cartilage group but also resulted in more complications at the same time. CONCLUSION: The results of this study indicates that complete septal extension grafts are efficient for the correction of unilateral cleft lip nasal deformities. However, since postoperative complications occur more frequently in the polyethylene group than in the septal cartilage group, caution is advised in using porous high-density polyethylene sheets in patients with cleft lip nasal deformities.

A traditional tie-over dressing may be applied to support the take of a skin graft. Although there are many advantage of this method, it has significant disadvantages, including time-consuming application. Furthermore, when the dressing is changed, the gauze becomes hard and can be stuck to the graft, causing damage and pain upon removal. The purpose of our study is to evaluate the effect of semi-occlusive dressing using polyurethane foam and film dressing(Allevyn(R), Opsite(R)) after full thickness skin graft. The authors treated 45 cases including burn scar contracture(n=38), syndactyly (n=1), absence of nipple-areolar complex(n=4), traumatic skin defect(n=1) and contact burn(n=1) with authors' method and 39 patients including burn scar contracture (n=39) with the tie-over dressing between 2000 and 2004. The patients in polyurethane foam and film dressing group ranged from 1 to 62 years of age (mean age, 15.1 years) and the patients in tie-over dressing group ranged from 2 to 60 years of age(mean age, 21.3 years). The postoperative results were analyzed according to the following measures: (1) the duration of graft-taking, (2) the admission period, (3) complications. Compared with the traditional tie-over dressing, polyurethane foam and film dressing was shown to be more successful in a reduced duration of graft-taking, in which was similar to the former in the rate of graft-taking, a reduced admission period and patient's discomfort. We concluded that semi-occlusive dressing using Allevyn(R) and Opsite(R) was an effective method after full thickness skin graft, which was easy to shape to difficult body locations, such as web spaces, fingers and maintains a moist environment for wound healing and does not stick to the wound.
