Autologous breast reconstruction utilizing a perforator flap is an increasingly popular method for reducing donor site morbidity and implant-related complications. However, aberrant anatomy not readily visible on computed tomography angiography is a rare albeit real risk when undergoing perforator flap reconstruction. We present an operative case of a patient who successfully underwent a bilateral breast reconstruction sourced from a unilateral abdominal flap divided into deep superior epigastric artery and superficial circumflex iliac artery flap segments.

Purpose: Zygoma is a major portion of the midfacial skeleton, forms the malar prominence and the three adjacent bony articulations. Zygoma fracture is a very common in facial trauma. Open reduction and rigid fixation of displaced zygoma fractures are necessary to avoid immediate and delayed facial asymmetry and depression. However, it is possible to happen the complications related to the plates and screws. So, we planned to treat the 24 patients of Group II, III, IV zygoma fractures with precise reduction and non-fixation method via intraoral approach. Methods: From August, 2006, to August, 2009, we treated 24 cases of zygoma fracture with reduction and non-fixation methods. Before the surgery, we choose the patients who could be treated with this method among the Group II, III, IV patients. Results: No patients in this study had postoperative complications such as displacement of bony fragments, facial depression and asymmetry, malocclusion, hypoesthesia. Satisfactory aesthetic and functional results can be obtained. Conclusion: In the treatment of the zygoma fracture, it is possible to treat with precise reduction and non-fixation method. The greatest advantage is to decrease the operative time, no need to wide dissection, no complications related to the plates and screws. For the using of this method, it is necessary to choose the adequate patients through the preoperative planning.

Purpose: The most accepted method for the reanimation of a paralyzed face is the two-stage method that combines cross-face nerve grafting with free-muscle transfer. Although the results of reconstruction with this method are satisfactory, there is an excessive delay between the stages, which prolongs the period of rehabilitation. In order to overcome this drawback, a one- stage, neurovascular free-flap reconstruction method using free neurovascular muscle flaps is introduced. Methods: From 1994 to 2004, 35 patients with longstanding facial palsy were treated. Fifteen patients underwent the single-stage reconstruction with the latissimus dorsi muscle, and 20 patients underwent the two-stage reconstruction method with the gracilis muscle. We compared the long-term results of the two methods of reconstruction. The mean follow-up period was 28.7 months for one-stage reconstruction, and 35.2 months for the two-stage, respectively. Results: In the patient group of the single stage reconstruction, both mouth corner excursion and animation grade were markedly improved at the final postoperative visit. Moreover, the first muscle contraction occurred earlier in this group, than in the two-stage reconstruction group. However, four patients in the single stage group never achieved a first muscle contraction or mouth corner excursion. Conclusion: Facial palsy is a very challenging condition for cosmetic surgeons to deal with. Traditional methods for treatment of chronic facial palsy use a two-stage muscle flap which is time-consuming and burdensome to patients, many of whom are averse to waiting 8 to 12 months to complete the two stages. The one-stage reconstruction method described herein uses a latissimus dorsi free-flap and has demonstrated consistent positive outcomes in clinical assessments.

Purpose: Mulliken's method allows for normal nasal and lip growth, which in turn forms a natural shape of the philtrum. Therefore, we used a modified Mulliken's method to correct unilateral and bilateral cleft lip nasal deformities and followed the patients for 10 years. Methods: Ninety-one patients, who had undergone repair of unilateral and bilateral cleft lip and nasal deformity simultaneously using Mulliken's method during the time period from June 1997 to June 2009, were enrolled into this study. To follow-up of the growth of the lips and nose after the operation, the following 5 anthropometric measurements were analyzed: nasal tip protrusion, columellar length, upper lip height, cutaneous lip height, and vermilion mucosa height. Results: Using this method, we obtained a result that there was no significant difference in the development of the lip compared to the normal control group, and that the bilateral cleft lip patients' nasal projection and columellar length was shorter than that in normal persons. Both measures were statistically significant. Conclusion: Mulliken's method is a superb surgical technique, which enables the normal development of the nose and lip, which further allows for the innate philtrum appearance. The author's result does not seem to be meaningful, because the normal rate of nasal growth is slow before adolescence; however, we recommend additional follow-up and accordant treatment, if needed, once the nasal growth is complete.

Objectives: The purpose of this study was to estimate the minimal clinically important difference (MCID) of mouth opening (MO) and patient satisfaction in surgically treated oral submucous fibrosis (OSMF) patients. Materials and Methods: The status of MO was collected preoperatively (T0), postoperatively at 3 months (T1), and at a minimum of 6 months postoperatively (T2). MCID was determined through the anchor-based approach with the change difference method, mean change method, and receiver operator characteristic curve (ROC) method. Results: In this study, 35 patients enrolled and completed postoperative follow-up (T2) averaging a duration of 18.1 months. At T1, using the change difference method, MO was 14.89 mm and the ROC curve exhibited a 11.5 gain in MO (sensitivity 81.8% and specificity 100%, area under the curve [AUC] of 0.902) and was classified as MCID as reported by patients. At T2, MCID of MO was 9.75 mm using the change difference method and 11.75 mm by the mean change method. The ROC curve revealed that the MCID of MO at T2 was 10.5 mm with 73.9% sensitivity and 83.3% specificity (AUC of 0.873). The kappa value was 0.91, confirming reliability of the data. Conclusion: This study demonstrated MCID values that indicate the clinical relevance of surgical treatment of OSMF if the minimum possible gain in MO is approximately 10 mm.

There has been considerable controversy as to the treatment method of dislocation of the acromioclavicular joint, so various operative treatment modalities have been suggested. We analyzed the results of 40 patients with acromio­clavicular dislocation, in whom twenty patients were treated by modified Phemister method and 20 patients by modified Weaver-Dunn method above follow-up two years. The purpose of this study was to compare the clinical results of two operative methods. According to Weitzman criteriae for clinical results, 12 cases were excellent, six cases good and two cases fair in modified Phemister method. But in modified Weaver-Dunn method, ten cases were excellent, eight cases good, one case fair and one case poor. In radiological result, coracoclavicular distance was measured at preoperative, postoperative and last follow-up period. The modified Phemister method was 6.lmm, 1.5mm and 2.4mm respectively, and the modified Weaver-Dunn method 7.8mm, 2.lmm and 2.5mm respectively. The complications were two cases of heterotopic ossification, one case of inadequate fixation and one case of K-wire breakage in modified Phemister method, and two cases of early fixation loss and one case of heterotopic ossification in modified Weaver-Dunn method. We obtained that the clinical, functional and radiological results showed no significant difference in two methods. The modified Phemister method was effective treatment for old patients in acute injuries due to short operation time and simple technique. The modified Weaver-Dunn method, as a reconstructive operation that reduces various complications for young and active male patients, was also good for getting the stability of coraco­clavicular ligament through clavicular bony union.

Purpose: Steatocystoma multiplex is a rare benign disease that occurred multiply on whole body surface. Many physicians have tried managing steatocystoma in variable methods. However it is hard to define the optimal way to cure steatocystoma. We performed both aspiration and excisional method to study the usefulness of both methods. Methods: A 28-year-old woman has asymptomatic multiple subcutaneous nodules on whole body. Most lesions were aspirated with 26-guage needled 3 cc syringe but large and purulent three nodules were excised. Results: We diagnosed the lesion histologically as steatocystoma multiplex. Aspirated wound healed without scar, excised wound remained scar but esthetically acceptable. Axillary lesion contained so clustered type cysts that was difficult to aspirate whole cyst. Thus additional excisional method was needed. Conclusion: There are many practical methods to cure steatocystoma. However, there is no appropriate method to cure it. Therefore we should select different therapeutic method according to anatomical location and cyst size. Especially at subcutaneous fat-rich lesion like axilla and abdomen, it is better to excise the clustered cyst than to aspirate.

Purpose: The presence of epicanthal fold and the absence of supratarsal fold are characteristics of Korean eyelids. There has been many surgical procedures to eliminate medial epicanthal fold but those procedures focus on the lengthening of horizontal palpebral fissure and the shortening of intercanthal distance so that the shape of eye had tendency to be sharp. The authors suggest that the supermedial shifting of epicanthal fold enhance the aesthetic result. Methods: From Sep 2006 to May 2007, total 17 women(mean age 22) with Type III epicanthal fold underwent epicanthoplasty using author's modified Uchida method. The design for epicanthoplasty was drawn superolaterally along epicanthal fold and split V-W plasty was done to shift the epicanthal fold superomedially. Also non-incisional double-eyelid operation was underwent. Results: The epicanthal fold was shifted in superomedially, intercanthal distance was shortened and double-eyelid was achieved. The patients were satisfied with the result and no major complication was noted. Conclusion: This method can be effective in correcting the epicanthal fold of Korean eyelid by shifting the epicanthal fold superomedially to make the shape of eye aesthetically without noticeable scar.

Background Restoring orbital volume in large blowout fractures is still a technically challenge to the orbital surgeon. In this study, we restored the orbital wall using the combination of transorbital and transnasal approach with additional supports from the paranasal sinuses, and we compared the surgical outcome to that of a conventional transorbital method. Methods A retrospective review of all patients with pure unilateral blowout fractures between March 2007 and March 2013 was conducted. 150 patients were classified into two groups according to the surgical method: conventional transorbital method (group A, 75 patients, control group), and the combination of transorbital and transnasal approach with additional supports from the paranasal sinuses (group B, 75 patients, experimental group). Each group was subdivided depending on fracture location: group I (inferior wall), group IM (inferomedial wall), and group M (medial wall). The surgical results were assessed by the Hertel scale and a comparison of preoperative and postoperative orbital volume ratio (OVR) values. Results In the volumetric analysis, the OVR decreased more by the experimental groups than each corresponding control groups (P<0.05). Upon ophthalmic examination, neither the differences among the groups in the perioperative Hertel scale nor the preoperative and postoperative Hertel scales were statistically significant (P>0.05). Conclusions Our surgical results suggest that orbital volume was more effectively restored by the combination of transorbital and transnasal approach with additional supports from the paranasal sinuses than the conventional method, regardless of the type of fracture.

Acetabular dysplasia is a condition defined by inadequate development of an individual's acetabulum. Individual diversity of the symptoms in this disease needs safe and accurate preoperative planning. Technologies that utilize multidimensional image information are thus important. The assessment method by Janzen et al. was suggested a coefficient method in evaluation of acetabular dysplasia. In this study, we applied it, using a three-dimensional computed tomography (3D CT) on the koreans. 19 cases of the normal hips and 4 cases of the acetabular dysplasia were investigated to evaluate the proved method; 3D CT was used to define the geometric center of the femoral head and to measure center edge angles at $10^{\circ}$ rotational increments around the acetabular rim. Mean and standard deviation in CEAs (Center Edge Angle) of normal 19 hips at $10^{\circ}$ rotational increments from anterior to posterior rim were determined, and termed as a 'normal curve'. Then this normal values were compared with the CEA data measured from 4 cases of acetabular dysplasia patiens. Quantative comparison of the CEA values between the normal cases and dysplasia cases was successfully demonstrated, and thus, we claim that this simple CT method of assessing acetabular dysplasia can be well applicable to diagnosis, quantification and surgical planning for adult acetabular dysplasia patients.
