The synchondrosis between the sixth and seventh costal cartilage is usually used for the base frame in autogenous ear reconstruction. If the synchondrosis is loose, a variety of modifications can be devised. This report introduces new methods for these problems. In cases of incomplete synchondrosis, only the surface of the base block margin was smoothly tapered without carving for the removal of the conchal deepening. The secure fixation of the two segments (helix and antihelix) to the base block using fine wire sutures gave stability to the unstable basal frame. After confirming that all the segments were assembled in one stable piece, the remaining conchal deepening of the basal framework was removed, and the outer lower portion of the basal cartilage was trimmed along its whole length. A total of 10 consecutive patients with microtia, ranging from 8 to 13 years old, were treated from 2008 to 2009. The follow-up period was 6 months to 2 years. Despite incomplete synchondrosis, the stable frameworks were constructed using the authors' method and aesthetically acceptable results were achieved. The proposed method can provide an easy way to make a stable cartilage framework regardless of the variable conditions of synchondrosis.

PURPOSE: Although the demand for the mammoplasty including reduction or reconstruction is remarkably increasing, the anthropometric measurement for the breast, especially about the nipple areola complex(NAC) of Korean women has not been reported recently. Therefore, the anthropometric measurement about the NAC was performed to suggest the standard size of NAC for Korean women. METHODS: Two hundred and twenty five female volunteers in 20's through 50's were included for the study. Questionnaires including the diameter of NAC, the diameter, height of nipple, age, marital status, delivery and lactation history were distributed to the volunteers and collected. RESULTS: The mean values of our study are as follows: the areola diameter is 30.93+/-10.07mm, the nipple diameter is 10.21+/-4.14mm and the height of nipple is 6.54+/-3.74mm. The diameter of nipple areola complex(NAC) is bigger in old ages. If the volunteers have the history of marriage, delivery and lactation, it is bigger, as well. The height of nipple closely related to individual characters except the correlation between height of nipple and age. CONCLUSION: It is important to have standard data for the nipple areola complex in order to have good aesthetic results of mammoplasty. Despite the importance, there are a few measurement data for the nipple areola complex(NAC) of Korean women. The result of our study is not the absolute parameter for breast surgery, however it can be used as the standard size for NAC in the Korean female during breast surger

PURPOSE: To reconstruct soft tissue defect on lower extremity especially combined with osteomyelitis, free flap with enough blood supplies is required. There are some instance when patients have inadequate recipient vessels for microanastomosis. Anastomosis with harvested vein graft can solve the problem. It may be more problematic or even increase recipient site complication. Cross leg free flaps using contra-lateral vessel can be a solution. METHODS: From 2005 to 2008, 12 cases of cross leg free flap were done for 12 patients(9 male, 3 female). External fixators used in all cases. The free flaps used were laissmus dorsi muscle flap(n=5), anterolateral thigh flap(n=4), gracilis muscle flap(n=2) and medial plantar artery fasciotaneous flap(n=1). In all cases, contralateral posterior tibial artery and vein were used as recipient pedicle. RESULTS: All flaps survived without additional operative procedures. There happened no complications such as hematoma or Infection. Sometimes patients needed further therapeutic exercise for fast movement recovery. CONCLUSION: Although cross leg free flaps require long period of bed resting and rehabilitation after pedicle cutting, It can be a practical alternative for soft tissue defect on lower distal extremity with inadequate recipient vessels for free flap on affected leg.

BACKGROUND: This article presents long-term outcomes after correcting secondary bilateral cleft lip nasal deformities using a refined reverse-U incision and V-Y plasty or in combination with a composite graft in order to elongate the short columella. METHODS: A total of forty-six patients underwent surgery between September 1996 and December 2008. The age of the patients ranged from 3 to 19 years of age. A bilateral reverse-U incision and V-Y plasty were used in 24 patients. A composite graft from the helical root was combined with a bilateral reverse-U incision in the 22 patients who possessed a severely shortened columella. The follow-up period ranged between 2 and 10 years. RESULTS: A total of 32 patients out of 46 were evaluated postoperatively. The average columella length was significantly improved from an average of 3.7 mm preoperatively to 8.5 mm postoperatively. The average ratio of the columella height to the alar base width was 0.18 preoperatively and 0.29 postoperatively. The postoperative basal and lateral views revealed a better shape of the nostrils and columella. The elongated columella, combined with a composite graft, presented good maintenance of the corrected position with no growth disturbance. A composite graft showed color mismatching in several patients. Twenty-six patients demonstrated no alar-columella web deformity and satisfactory symmetry of the nostrils. Four patients experienced a drooping and overhanging of the corrected alar-columella web. CONCLUSIONS: A bilateral reverse-U incision with V-Y plasty or in combination with a composite graft was effective in correcting secondary bilateral cleft lip nasal deformity.

Oncoplastic surgery has revolutionized the field of breast conserving surgery (BCS). The final aims of this technique are to obtain an adequate resection margin that will reduce the rate of local recurrence while simultaneously improving cosmetic outcomes. To obtain successful results after oncoplastic surgery, it is imperative that patients be risk-stratified based on risk factors associated with positive margins, that relevant imaging studies be reviewed, and that the confirmation of negative margins be confirmed during the initial operation. Patients who had small- to moderate-sized breasts are the most likely to be dissatisfied with the cosmetic outcome of surgery, even if the defect is small; therefore, oncoplastic surgery in this population is warranted. Reconstruction of the remaining breast tissue is divided into volume displacement and volume replacement techniques. The use of the various oncoplastic surgeries is based on tumor location and excised breast volume. If the excised volume is less than 100 g, the tumor location is used to determine which technique should be used, with the most commonly used technique being volume displacement. However, if the excised volume is greater than 100 g, the volume replacement method is generally used, and in cases where more than 150 g is excised, the latissimus dorsi myocutaneous flap may be used to obtain a pleasing cosmetic result. The local recurrence rate after oncoplastic surgery was lower than that of conventional BCS, as oncoplastic surgery reduced the rate of positive resection margins by resecting a wider section of glandular tissue. If the surgeon understands the advantages and disadvantages of oncoplastic surgery, and the multidisciplinary breast team is able to successfully collaborate, then the success rate of BCS with partial breast reconstruction can be increased while also yielding a cosmetically appealing outcome.

PURPOSE: We report our initial experience with transurethral injection of autologous adipose-derived regenerative cells (ADRCs) for the treatment of urinary incontinence after radical prostatectomy. MATERIALS AND METHODS: After providing written informed consent, six men with persistent urinary incontinence after radical prostatectomy were enrolled in the study. Under general anesthesia, about 50 mL of adipose tissue was obtained from the patients by liposuction. ADRCs were obtained by separation with centrifugation using the Celution cell-processing device. A mixture of ADRCs and adipose tissue were transurethrally injected into the submucosal space of the membranous urethra. Functional and anatomical improvement was assessed using a 24-h pad test, validated patient questionnaire, urethral pressure profile, and magnetic resonance imaging (MRI) during 12-week follow-up. RESULTS: Urine leakage volume was improved with time in all patients in the 24-h pad test, with the exemption of temporal deterioration at the first 2 weeks post-injection in 2 patients. Subjective symptoms and quality of life assessed on the basis of questionnaire results showed similar improvement. The mean maximum urethral closing pressure increased from 44.0 to 63.5 cm H2O at 12 weeks after injection. MRI showed an increase in functional urethral length (from 6.1 to 8.3 mm) between the lower rim of the pubic bone and the bladder neck. Adverse events, such as pelvic pain, inflammation, or de novo urgency, were not observed in any case during follow-up. CONCLUSION: This study demonstrated that transurethral injection of autologous ADRCs can be a safe and effective treatment modality for postprostatectomy incontinence.

Archives of Plastic Surgery 2012;39(4):301-308
In the treatment of mandibular condyle fracture, conservative treatment using closed reduction or surgical treatment using open reduction can be used. Management of mandibular condylar fractures remains a source of ongoing controversy in oral and maxillofacial trauma. For each type of condylar fracture,the treatment method must be chosen taking into consideration the presence of teeth, fracture height, patient'sadaptation, patient's masticatory system, disturbance of occlusal function, and deviation of the mandible. In the past, closed reduction with concomitant active physical therapy conducted after intermaxillary fixation during the recovery period had been mainly used, but in recent years, open treatment of condylar fractures with rigid internal fixation has become more common. The objective of this review was to evaluate the main variables that determine the choice of an open or closed method for treatment of condylar fractures, identifying their indications, advantages, and disadvantages, and to appraise the current evidence regarding the effectiveness of interventions that are used in the management of fractures of the mandibular condyle.

The incidence of condylar fractures is high, but the management of fractures of the mandibular condyle continues to be controversial. Historically, maxillomandibular fixation, external fixation, and surgical splints with internal fixation systems were the techniques commonly used in the treatment of the fractured mandible. Condylar fractures can be extracapsular or intracapsular, undisplaced, deviated, displaced, or dislocated. Treatment depends on the age of the patient, the co-existence of other mandibular or maxillary fractures, whether the condylar fracture is unilateral or bilateral, the level and displacement of the fracture, the state of dentition and dental occlusion, and the surgeonnds on the age of the patient, the co-existence of othefrom which it is difficult to recover aesthetically and functionally;an appropriate treatment is required to reconstruct the shape and achieve the function ofthe uninjured status. To do this, accurate diagnosis, appropriate reduction and rigid fixation, and complication prevention are required. In particular, as mandibular condyle fracture may cause long-term complications such as malocclusion, particularly open bite, reduced posterior facial height, and facial asymmetry in addition to chronic pain and mobility limitation, great caution should be taken. Accordingly, the authors review a general overview of condyle fracture.

Temporomandibular joint(TMJ) and dental occlusion are important in functional aspect as well as in cosmetic aspect for craniofacial surgery such as orthognathic and traumatic surgery. During these operations, appropriate maxillomandibular fixation(MMF) is especially necessary to conserve or reconstruct, dynamic TMJ and functional occlusion. Arch bar is one of the most popular method to gain proper MMF. Seventeen patients including 5 patients with mandibular fracture, 12 patients with orthognathic surgery(6 patients had relatively normal occlusion, however 6 patients had facial anomalies such as hemifacial microsomia with irregular occlusal plane.) were joined in this study. Arch bar was contoured on the dental cast, which was prepared for model surgery, prior to apply it on the facial anomaly patient. On using pre-contoured arch bar, patients felt better during the procedure and surgeons saved time. Moreover, well-contoured arch bar promises precise transmission of force on the bone, which implies surgeons do not need to worry about the occlusion while fixing bony structures. Authors suggest how to apply arch bar to satisfy basic theories about dental row and occlusion based on the experience. In addition, it is proposed to contour arch bar on the dental impression prior to apply it on the patient who has irregular and complex occlusal plane.

Cleft palate and congenital alveolar synechia is a rare syndrome. Only eight cases have been previously reported. It consists of a spectrum of facial anomalies always including cleft palate and congenital alveolar synechiae without other abnormalities. This report described an unusual case of congenital alveolar synechial band spanning posterior alveolar of the two jaws with cleft palate. Previously reported cases showed bilaterally or anteriorly located fibrous band. In our department, a new born revealed unilateral posterior synechia. Under brief intravenous sedation, synechium was divided using bipolar diathermy in the nursery at 3 days of age because of poor feeding. This division allowed full jaw opening after brief passive exercise. The patient is growing and maturing as expected with no complications. This patient is supposed to be the first reported case of isolated unilateral alveolar synechium combined with cleft palate in the worldwide.
