이차 구순비성형술을 받고자 본과에 내원한 편측성 완전 구순구개열을 가진 29세 남자 환자에서 상방으로 반전된 큐피드활과 적순부의 휘파람 변형을 교정하기 위해 중복 Z-성형술을 시행하였다. 수술 후에 반전된 큐피드활이 정상적인 형태로 재건되고 휘파람 변형이 없어졌으며 상순의 긴장도가 완화되었다. 중복 Z-성형술시 적순부 내에서만 피판을 형성하므로 피부에는 새로운 반흔이 생기지 않아 심미적으로 만족스러웠고 상순결절은 더욱 볼록해 졌다. 수술 4년경과 후 큐피드활은 부드러운 곡선으로 좌우 대칭을 이루고 매우 자연스럽게 보였으며 장기적인 추적관찰 결과 양호한 결과를 보였다. 중복 Z-성형술은 반전된 큐피드활의 교정시 다른 수술방법에 비해 술식이 간단하고 주위조직 손상이 적으며 휘파람 변형의 교정도 가능한 좋은 방법이라고 사료된다.

Purpose: Who may dare to state that optimal choice of treating nasal bone fracture is closed reduction? Few decades of authors' experience in nasal bone fracture has lead to believe that more active and assertive approach in nasal bone fracture by performing simultaneous lateral osteotomy may be applied in proper indications to acquire more accurate reduction and cosmetically satisfying result. Methods: From May 2008 to October 2009, among 241 nasal bone fracture patients, 20 patients underwent simultaneous lateral osteotomy with nasal bone fracture reduction. Followed by rigid septal correction, nasal cavity is packed to stabilize the fracture segment for safer osteotomy. Through intranasal incision, in selected cases of difficult reduction or for cosmetic purposes, various types of lateral osteotomy was performed corresponding to the fracture anatomy, conditions of the nasal cavity. Postoperative nasal packing was retained for one week and nasal dorsum splint for 3 weeks. Results: Lateral osteotomy was utilized for difficult cases of closed reduction, for correction of wide nose, hump and deviation in 9, 5, 2, and 4 cases, respectively. Patient satisfaction was scaled 90% in satisfaction and moderate in 10% (2 cases), complaining of mild nasal tip deviation. Physicians detected 2 cases of apparent deformity with patient recognition; one patient with mild step deformity at the osteotomy site and the other patient with minimal implant mobility. Conclusion: By accompanying profound understanding of the fracture anatomy, more active and assertive approach in nasal fracture reduction can be coincide with simultaneous lateral osteotomy to reduce the rate of secondary deformity and to obtain more cosmetically satisfying result.

Purpose: The purpose of our study is the comparison of radiological and clinical outcomes between modified distal chevron osteotomy and proximal metatarsal osteotomy for the patients who had moderate to severe hallux valgus deformity. Materials and Methods: In this retrospective study, we included 54 patients (65 feets) who underwent the operation of moderate to severe hallux valgus in our hospital from May 2007 to August 2010. Our study compares two groups. For Group 1, a modified distal chevron osteotmy and a distal soft tissue procedure were done and for Group 2, a proximal metatarsal osteotmy and a distal soft tissue procedure were done. The group 1 were 29 feets; the group 2 were 36 feets, and the average follow up was 9 months. Results: The radiological results show that the hallux valgus angle and the first-second intermetatarsal angle were significantly decreased in two groups. In each parameter, the correction of the hallux valgus angle was $19.1^{\circ}$ (Group 1) and $24.3^{\circ}$ (Group 2), the correction of the first-second intermetatarsal angle was $9.6^{\circ}$ (Group 1) and $10.3^{\circ}$ (Group 2). Shortening of the first metatarsal length was 0.87 mm (Group 1) and 0.77 mm (Group 2). There are no significant clinical results (American Orthopaedic Foot and Ankle Society score, AOFAS score) in two groups. Conclusion: It is thought that a modified distal chevron osteotomy and a distal soft tissue procedure are a considerable operative treatment of moderate to severe hallux valgus deformity because of the similar cilinical results, more simple operative techniques, and less complications than a proximal metatarsal osteotomy.

목적: 다발성 섬유성 이형성증에서 대퇴골두의 침범 부위 정도에 따라 분류하여 변형 정도를 분석하고 치료 경과에 대한 결과를 보고하고자 한다. 대상 및 방법: 1987년 3월부터 2014년 3월까지 전남대학교병원에 내원한 23명의 환자를 후향적 연구를 실시하였다. 대퇴골두 침범 부위에 따라 대퇴골두의 골단판 반흔 및 성장판을 침범하지 않은 Type I, 골단판 반흔 및 성장판을 침범한 Type II로 구분하였다. 단순방사선 촬영을 통해 대퇴경간각 및 비구-전자간 거리를 측정하였으며 측면사진을 통해 전방만곡을 측정하였다. 하지의 teleoroentgenogram을 통해 하지부동 및 하지 역학축의 변화를 측정하였다. 골스캔을 통해 하지병변의 위치와 변형을 확인하였다. 변형 교정 및 골절 치료를 위한 내고정술 전후의 대퇴경간각, 비구-전자간 거리를 비교하여 수술 후 교정의 소실 정도를 확인하였다. 결과: 총 23명(46하지) 중 23명(28하지)에서 근위 대퇴부에 병변이 있었다. Type I은 15/23명(16/28하지), Type II는 9/23명(12/28하지)이었다. 근위 대퇴골의 술 전 대퇴경간각은 Type I에서 116.8도, Type II에서 95.3도를 보였고, 비구-전자간 거리는 Type I에서 12.08 mm, Type II에서 -5.54 mm를 보여 Type II에서 의미 있게 변형이 심하였다. 수술 직후 변형 교정에 뚜렷한 호전을 보였으나 시간이 경과함에 따라 Type II의 경우 변형 교정이 소실됨을 보였다(대퇴경간각 Type I: 133.8-130.8도, Type II: 128.6-116.9도, 비구-전자간 거리 Type I: 17.66-15.72 mm, Type II: 7.44-4.16 mm). 전방 만곡은 Type I에서 평균 12.74도, Type II에서 평균 20.19도를 보였다. 실제 하지부동을 보인 총 9명에서 평균 12 mm 의 차이를 보였으며, 하지 역학축은 술 전을 기준으로 외측 편위 4하지, 내측 편위 7하지를 보였다. 결론: 다발성 섬유성 이형성증에서 대퇴골두를 침범한 경우 대퇴경간각 및 비구-전자간 거리, 대퇴골의 전방 만곡에서 훨씬 심한 변형을 보이고 수술 후 변형 교정의 소실 양상을 보여 병변의 대퇴골두 침범 여부가 환자의 예후에 중요한 인자임을 알 수 있었다. 내외반 변형뿐만 아니라 전방 만곡 등의 측면상의 변형 및 하지 역학축, 하지부동 등 전반적인 하지의 정렬을 고려해야 할 것으로 생각된다.

Purpose: The Mulliken's method is a one of the very excellent technique to correction of the unilateral cleft lip. It could decrease the need of additional operation and second operation by the early simultaneous correction of unilateral cleft lip and nasal deformity, at a time. Numerous procedures were advocated for the correction of nasal deformity, but with general dissatisfaction of the results, it became obvious that no one procedure is the ideal one. The authors have been operating on unilateral cleft lip by Mulliken's method and long term follow - up of postoperative result was evaluated. Methods: The authors have done long term follow - up of result in the 75 cases unilateral cleft lip patient, during 1 ~ 7 years. That was repaired by simultaneous correction of cleft lip and nasal deformity by Mulliken's method at the period from June, 1997 to December, 2007. The patients were unilateral complete cleft lip 39 cases, unilateral incomplete cleft lip 36 cases. In the severe complete cleft lip cases, lip adhesion operation was done before definite operation. The mean age of unilateral cleft lip operation was 3.2 months. Five anthropometric parameters, which were upper lip, cutaneous lip and vermilion mucosa height, nasal tip protrusion, columella length were measured by Sliding Vernier Caliper. The anthropometric analysis was performed preoperative and postoperative at 6 months, 3, 5 and 7 years and the results were com pared with those of age - matched, normal children. T - tests were used to analyze the differences between the measurements. Results: Long - term postoperative results were evaluated by anthropometrically. Most patients showed adequate growth of upper lip height, vermilion mucosa height and columella length. But nasal tip protrusion was relatively short compare with normal value. Incomplete cleft lip group was nearly normal growth results than complete cleft lip group. Conclusion: In conclusion, we could make harmonious Cupid's bow, natural philtrum and lip, appropriate nasal shape by Mulliken's method. But nasal tip protrusion was under the normal values on complete and incomplete group. And incomplete group was more good results than complete group. We have experienced repair of cleft lip by Mulliken's method with 75 cases of unilateral cleft lip patients and conclude that it was very useful and good method.

Background Pectus excavatum is less common in females than in males, and it often aggravates a coexistent breast asymmetry. We conducted a study comparing female patients' versus medical professionals' evaluation of pectus excavatum repair to assess differences in aesthetic outcome ratings. Moreover, we evaluated the influence of surgical correction on patients' self-perception. Methods Of 30 female patients who were initially screened, 18 patients (mean age, 20 years) who underwent bar removal after surgical correction of pectus excavatum deformity participated in the survey (60%). They completed a questionnaire rating their appearance before and after surgery and responded to a psychological questionnaire about the changes that they had experienced. The mean interval between pectus bar removal and evaluation was 28 months. Standardized preoperative and postoperative patient photographs were evaluated using the same questionnaire by a panel of medical professionals and students (n=24) and the results were compared. Results Patients rated their preoperative deformity as more severe than the other evaluators, revealing the significant impact of the deformity on patients' self-perception. Postoperatively, patient and professional evaluations were much better than before and were very similar. The psychological evaluation showed a clear improvement in well-being. The ratings of the medical professionals were not influenced by their degree of medical education. Conclusions Surgical correction of pectus excavatum in female patients positively influences body perception and psychological well-being. It should therefore not be considered as a merely aesthetic correction, but as an important procedure to restore a patient's self-perception.

Purpose: Reconstructive surgeries for equinocavovarus foot deformities are quite variable, including hind-midfoot osteotomy or arthrodesis, soft tissue procedure, tendon transfers, etc. Comprehensive evaluation of the deformity and its etiology is mandatory for achievement of successful deformity correction. Few studies in this field have been reported. We report on the clinical and radiographic outcome of reconstruction for cavovarus foot deformities. Materials and Methods: The study is based on 16 feet with cavovarus foot deformities that underwent bony and soft tissue reconstructive surgery from 2004 to 2008. We evaluated the etiologies, varieties of surgical procedures performed, pain score, functional scores, and patient satisfaction and measured the radiographic parameters. Results: The average age at the time of surgery was 39.4 years old, with a male/female ratio of 9/4 and an average follow-up period of 23.9 months (range, 12~49 months). The etiologies of the cavovarus deformity were idiopathic 7 feet, residual poliomyelitis 5 feet, Charcot-Marie-Tooth disease 2 feet, and Guillain-Barre syndrome and hemiplegia due to cerebrovascular accident sequela 1 foot each. Lateral sliding calcaneal osteotomies were performed in 12 feet (75%), followed by Achilles tendon lengthening and plantar fascia release in 11 feet (69%), and first metatarsal dorsiflexion osteotomy/arthrodesis and tendon transfer in 10 feet (63%). Visual analogue scale pain score showed improvement, from an average of 4.2 to 0.5 points. American Orthopaedic Foot and Ankle Society ankle-hindfoot score showed significant improvement, from 47.8 to 90.0 points (p<0.05). All patients were satisfied. Ankle range of motion improved from $27.5^{\circ}$ to $46.7^{\circ}$. In radiographic measurements, calcaneal pitch angle improved from $19.1^{\circ}$ to $15.8^{\circ}$, Meary angle from $13.0^{\circ}$ to $9.3^{\circ}$, Hibb's angle from $44.3^{\circ}$ to $37.0^{\circ}$, and tibio-calcaneal axis angle from varus $17.5^{\circ}$ to varus $1.5^{\circ}$ Conclusion: We achieved successful correction of cavovarus foot deformities by performing appropriate comprehensive reconstructive procedures with improved functional, radiographic measures and high patient satisfaction.

Objective: The aim of this study was to evaluate the skeletal and dentoalveolar changes after miniscrew-assisted rapid palatal expansion (MARPE) in young adults by cone-beam computed tomography (CBCT). Methods: This retrospective study included 14 patients (mean age, 20.1 years; range, 16-26 years) with maxillary transverse deficiency treated with MARPE. Skeletal and dentoalveolar changes were evaluated using CBCT images acquired before and after expansion. Statistical analyses were performed using paired t-test or Wilcoxon signed-rank test according to normality of the data. Results: The midpalatal suture was separated, and the maxilla exhibited statistically significant lateral movement (p < 0.05) after MARPE. Some of the landmarks had shifted forwards or upwards by a clinically irrelevant distance of less than 1 mm. The amount of expansion decreased in the superior direction, with values of 5.5, 3.2, 2.0, and 0.8 mm at the crown, cementoenamel junction, maxillary basal bone, and zygomatic arch levels, respectively (p < 0.05). The buccal bone thickness and height of the alveolar crest had decreased by 0.6-1.1 mm and 1.7-2.2 mm, respectively, with the premolars and molars exhibiting buccal tipping of $1.1^{\circ}-2.9^{\circ}$. Conclusions: Our results indicate that MARPE is an effective method for the correction of maxillary transverse deficiency without surgery in young adults.

Objective: The aim of this study was to evaluate the stability of bimaxillary surgery involving bilateral intraoral vertical ramus osteotomy performed with or without presurgical miniscrew-assisted rapid palatal expansion (MARPE) in adult patients with skeletal Class III malocclusion. Methods: A total of 40 adult patients with skeletal Class III malocclusion were retrospectively divided into two groups (n = 20 each) according to the use of MARPE for the correction of transverse maxillomandibular discrepancy during presurgical orthodontic treatment. Serial lateral cephalograms and dental casts were analyzed until 6 months after surgery. Results: Before presurgical orthodontic treatment, there was no significant differences in terms of sex and age between groups. However, the difference of approximately 3.1 mm in the maxillomandibular intermolar width was statistically significant (p < 0.001). Two days after surgery, the mandible had moved backward and upward without any significant intergroup difference. Six months after surgery, the maxillary intercanine (2.7 ± 2.1 mm), interpremolar (3.6 ± 2.4 mm), and intermolar (2.0 ± 1.3 mm) arch widths were significantly increased (p < 0.001) relative to the values before presurgical orthodontic treatment in the MARPE group; these widths were maintained or decreased in the control group. However, there was no significant difference in surgical changes and the postsurgical stability between the two groups. No significant correlations existed between the amount of maxillary expansion and postsurgical mandibular movement. Conclusions: MARPE is useful for stable and nonsurgical expansion of the maxilla in adult patients with skeletal Class III malocclusion who are scheduled for bimaxillary surgery.

A 5-week old Thoroughbred foal was presented with severe left carpal valgus. Radiographs of the dorsopalmar projections confirmed the deviation was 14 degrees. Surgery using a single-position screw traversing the physis of the distal radius was performed. The limb was almost straight (2 degrees) 3 weeks after surgery. Visual/radiograph follow-up 7 months after screw removal revealed no over-correction after removal of the screw. Transphyseal bridging using a single-position screw without lateral periosteal transection of distal radius was successful for the correction of foals with this condition.
