The temporalis fascia graft has been widely used in the correction of nasal deformities. The fascia can be used alone or combined for augmentation rhinoplasty. The fascia graft provides adequate coverage, contour, and bulk on the profile of the nose, as well as an inconspicuous donor site. A depressed radix area can be successfully corrected by the fascia graft. We present two cases of nasal radix augmentation by using temporalis fascia graft. Two male patients presented with the skeletal class III malocclusion and the depressed radix. A planned orthognathic surgery and the temporalis fascia graft to the radix were performed. The malocclusion and the profile of the patients were markedly improved after the operation. Not only the radix but also the nose was improved in its size and length. There was no noticeable resorption or displacement of the radix area at follow-up. The temporalis fascia graft could be an appropriate surgical technique in radix augmentation and nose lengthening.

Background: Funnel chest is one of the most common anomaly of chest wall, which is manifested by depression of sternum and costal cartilage. Popular operative methods were Ravitch operation and Wada operation. Material and Method: From 1983 to 1996, 21 cases of funnel chest were corrected surgically in the department of thoracic surgery, National Medical Center. Investigated age and sex distribution, combined anomaly,clinical symptom, degree of correction and complication, postoperative satisfaction. We used 2 different surgical methods, one was Wada & its variants(17 cases), the other was Ravitch and it variants(4 cases). Most of operative indications were cosmetic problems. Result: The pre-operative Welch index was 4.188, but this index decreased to 3.46 after the operations.(p=0.046) The degree of correction was higher in Wada & it variant operation than the modified Ravitch operation.(p=0.54) Their results were satisfactory in 20 patients, while unsatisfactory in 1 patient because of a k-wire fracture. There was no recurrence of chest wall depression or postoperative death during the OPD follow up period. Conclusion: We recommend Wada operation in symmetric and small degree of depressive chest wall deformity in preand post school age.

Radical paring of the cleft edge during primary cleft lip operation or repeated secondary surgeries can result in tightness of the upper lip. In case, the degree of the resulting side-to-side tension is very severe, the possibility of a lip switch flap must be considered. When the lip tightness accompanies a loss of more than two-thirds of the Cupid's bow, an Abbe flap is an alternative. The disadvantages of Abbe flap are scar formation on the lower lip, design of incision line on the upper lip, disharmony of colors, and the dysfunction of the orbicularis muscle. These problems have been recognized in the literature and extreme discretion has been advised in its application. We experienced four cases of Abbe flap operation which were designed differently to correct the secondary unilateral or bilateral cleft-lip nasal deformities. The Abbe flap operations resulted in removal of the scars and tightness of the upper lip, reconstruction of the Cupid's bow, lengthening of the columella, and therefore secondary cleft-lip nasal deformity could be corrected. It is thought that carefully applied Abbe flap is an appropriate method to relieve horizontal tightness or flattening of the upper lip which occured after primary operation of cleft lip.

There are still some controversies regarding one stage repair of pectus deformity with congenital heart disease due to probable complications after extensive resection of deformed cartilages. We performed Nuss operation with simul-taneous intracardiac repair in 8 year old patient with pectus excavatum and partial atrioventricular septal defect. The result of operation was satisfactory without prolongation of operation time, bleeding or instability of chest wall.

Proper positioning of maxillary incisors is key to success of surgery combined treatment. Establishing surgery plan would be a difficult job if maxillary incisors are lost. Patient who lost all of her maxillary incisors due to accident came for orthodontic treatment. Through careful modification of maxillary archform, pre-surgical orthodontic treatment was conducted with four prosthetic space consolidation. Position of incisors was decided by help of 3D prosthetic set-up, and 1-jaw surgery was planned. After relative short treatment period of 28 months, final prosthesis was done. When alveolar bone loss happens, harmonious prosthesis of upper incisors is difficult. Utilizing mandibular set-back surgery and incisor positioning using 3D set-up could make a better environment for treatment outcome. Strategic pre-surgical orthodontic treatment can allow shorter time and less number of prosthetics.

Although current surgical techniques have reduced the incidence of malunion, it is still observed because of the complexity of the fracture or associated injuries. Osteotomy is needed when the amount of malunion is expected to result in an overload of cartilage and instability of the joint. Preoperative planning is essential when performing an osteotomy for malunion. Inadequate planning can result in serious complications, such as iatrogenic malalignment, intraoperative fracture, postoperative recurrence of deformity, or soft tissue injuries. In addition, a poor functional result can occur secondary to poor patient selection. This review article includes the surgical indications and planning to correct malunion. Various methods of corrective osteotomy are described according to the kinds of plane and fixation implants.

The pectus excavatum is the most common deformity of chest wall. The most common cause of surgical correction is cosmetic problem. From January 1981 to July 1996, 24 patients had undergone surgery for pectus excavatum and they were corrected by Ravitch operation(n=4) or modified Wada operation(n=20) respectively. We analyzed each surgical cases according to age, sex, chief complaint, degree of deformity, EKG findings, complications and satisfaction degree of patient. In some cases, we measured Welch index preoperatively and postoperatively. The postoperative complications were wound infection in two, pneumothorax in two and reccurrence in one. The average value of Welch index was significantly improved from 5.86$\pm$0.51 preoperatively to 4.10$\pm$0.51 postoperatively(P<0.05). The results by Humphreys' criteria were satisfiable in 88%(excellent 71%, good 17%). The findings of this study suggest that surgical correction of pectus excavatum with modified Wada rocedure and submammary s in incision is effective method in physical and psychiatric aspect.

Purpose: To evaluate the treatment result in polyostotic fibrous dysplasia classified according to the involvement of the femoral head. Materials and Methods: Twenty-three patients from March 1987 to March 2014 were reviewed retrospectively. Patients with no involvement of the physeal scar in the femoral head were classified as Type I, and those with involvement of the physeal scar were classified as Type II. A plain radiograph was used to measure the femoral neck shaft angle, articulo-trochanteric distance (ATD), and anterior bowing through the lateral view. A teleoroentgenogram of the lower limb was used to measure the leg length discrepancy and lower extremity mechanical axis. The pre- and postoperative femoral neck-shaft angle and ATD were compared to assess the degree of correction of the deformity. Results: Among a total of 46 cases (23 patients), 28 cases (23 patients) had lesions in the proximal femur. Type I were 16/28 cases (15/23 patients) and Type II were 12/28 cases (9/23 patients). The preoperative proximal femoral neck-shaft angle was 116.8° in Type I and 95.3° in Type II. The ATD was 12.08 mm in Type I and -5.54 mm in Type II. The deformity correction showed significant improvement immediately after surgery, the deformity correction was lost in Type II (neck shaft angle Type I: 133.8°-130.8°, Type II: 128.6°-116.9°, and ATD Type I: 17.66-15.72 mm, Type II: 7.44-4.16 mm). The extent of anterior bowing was 12.74° in Type I and 20.19° in Type II. The mean differences of 12 mm between the 9 patients who showed a leg length discrepancy and the lower extremity mechanical axis showed 4 cases of lateral deviation and 7 cases of medial deviation. Conclusion: In polyostotic fibrous dysplasia, when the femur head is involved, the femur neck shaft angle, ATD, and anterior bowing of the femur had more deformity, and the postoperative correction of deformity was lost, suggesting that the involvement of the femoral head was an important factor in the prognosis of the disease.

Angular limb deformities (ALD) are common in foals. A 30-days-old Thoroughbred foal was presented for the evaluation of severe ALD of the both forelimbs. On radiographic examination, both distal radiuses were diagnosed as valgus angular limb deformities. But the degree of deviation of right forelimb was so severe that we tried to correct one after the other. We tried new surgical correction method combination of one screw implant on medial aspect for growth retardation and periosteal transection on lateral aspect of the right forelimb. 40 days later, successfully corrected and then removed the screw. After the right forelimb correction, the periosteal transection on left forelimb was performed. We did the inhalation anesthesia using isoflurane. There were no complications such as fibrosis over the screw heads, and overcorrection that produces an opposing deformity identified. These results suggest that combination of one screw implant and periosteal transection technique is able to be a safe and effective method to correct severe ALD in the foal.
