Congenital auricular deformities may be either deformational or malformational. Malformational anomalies present with a skin or cartilage shortage. Two cases with congenital cleft earlobe were presented. A new surgical technique using a two-layered repair with front and back flaps were introduced. She waited to begin wearing earrings until six months after the surgery to prevent possible scar contracture. The patients were followed up for a period ranging from 3 to 14 months. The earlobe volume deficiency was replaced, and acceptable scar maturation was obtained.

Purpose Displaced lateral end fracture of clavicle and acromioclavicular dislocation type Ⅲ∼Ⅵ may be required surgical treatment. Material and Methods : From May 1998 to March 2001, we operated with Welter plate with minimal incision by one surgeon. Immediately, pendulum and passive exercise was initiated after surgery. The shoulder function was evaluated using UCLA score. Average follow up was on 28(12∼45) months. Results : All 11 patients were regained satisfactory function. Average UCLA score was 31.9(29~35) at last follow up. Conclusion . The merit of Welter plate fixation with minimal incision is simple technique, reduced surgical time, smaller scar than large plate, strong fixation, early exercise, reduced implant failure. The disadvantage is expensive, skin irritatatation by long hook. But Welter plate fixation with minimal incision is a good method of internal fixation and excellent clinical result in surgical treatment of type H displaced lateral end fracture of the clavicle and type Ⅲ∼Ⅵ acromioclavicular dislocation.

Objectives : This study will broaden understanding of acupotomy therapy through comparison of side effects and complication which can be caused by the mechanism of treatment, surgical methods, and procedure by acupotomy therapy and epidural neuroplasty. Moreover, through an in-depth analysis of headache affected by two procedures, this research is supposed to find prospective cures for headache after acupotomy therapy. Methods : To compare acupotomy therapy with epidural neuroplasty this research was done using a comparative analysis eight theses about acupotomy therapy since 1995, as well as eleven theses about epidural neuroplasty since 2000. Other theses and data were used as references in the process of comparative analysis. Results : Acupotomy therapy and epidural neuroplasty, new treatments of damaged discs in the spine and stenosis made in 1990s, have the mechanism of treatment in common in that adhesion, a node or scar caused by the soft tissue damage is removed by putting catheter or acupuncture into the lesions. Epidural neuroplasty has additional injection into the lesions, which is different from acupotomy therapy in the process of surgical procedure. There are various reports of positive effects about curative effect in these two treatments. The two procedures may cause various complications. Headache may be a complication after surgery. The headache after acupotomy therapy is characterized as being an ache in the body, which is similar to that of post-dural puncture headache in the outbreaks and symptom. Headache after percutaneous epidural neuroplasty appears in general, which is similar to a headache as a result of the increased pressure of the brain spinal cord regardless of posture. Conclusions : Although they are alike in the mechanism of treatment, surgical methods and side effects, and complication after they are carried out as a result of analyzing theses related to acupotomy therapy and percutaneous epidural neuroplasty, there is a difference in aspects and mechanism of headaches experienced after the procedure.

Currently, robot-assisted latissimus dorsi muscle flap (RLDF) surgery is used in treating patients with Poland syndrome and for breast reconstruction. However, conventional RLDF surgery has several inherent issues. We resolved the existing problems of the conventional system by introducing the da Vinci single-port system in patients with Poland syndrome. Overall, three patients underwent RLDF surgery using the da Vinci single-port system with gas insufflation. In the female patient, after performing RLDF with silicone implant, augmentation mammoplasty was also performed on the contralateral side. Both surgeries were performed as single-port robotic-assisted surgery through the transaxillary approach. The mean operating time was 449 (335-480) minutes; 8.67 (4-14) minutes were required for docking and 59 (52-67) minutes for robotic dissection and LD harvesting. No patients had perioperative complication and postoperative problems related to gas inflation. The single-port robot-assisted surgical system overcomes the drawbacks of previous robotic surgery in patients with Poland syndrome, significantly shortens the procedure time of robotic surgery, has superior cosmetic outcomes in a surgical scar, and improves the operator's convenience. Furthermore, concurrent application to another surgery demonstrates the possibility in the broad application of the robotic single-port surgical system.

Background and Objective：A post-operative hypertrophic scar of the anterior neck is the leading complaint of the patients who underwent conventional thyroid surgery. In order to minimize the post-operative scar of the anterior neck, we performed thyroidectomy via axillary approach using operating microscope and a specialized retractor to determine technical feasibility. Patients and Methods：From January 2005 to December 2006, we performed thyroidectomy via axillary approach under operating microscope(f=400mm, ${\times}2.5$；OPMI $pico^{(R)}$；Zeiss, Germany) for benign unilateral nodule in 25 cases(all female, average age 34.5yrs). Under general anesthesia less than 7cm of skin incision was made in the axilla of ipsilateral side. A subcutaneous tunnel went over the pectoralis major muscle and the clavicle, and then through the sternocleidomastoid muscle and sternothyroid muscle was excised. The area around the thyroid was sufficiently dissected, and then a retractor designed for exposure via axillary approach was placed within the tunnel and under operating microscope thyroidectomy was performed. Results：There were 17 cases of thyroid nodulectomy and 8 cases of subtotal lobectomy. The mean average operative time was 102.64minutes. Postoperative complications included one case of postoperative bleeding, one case of temporary vocal cord paralysis, two cases of delayed wound healing, two cases of paresthesia of shoulder and arm, and two cases of hypertrophic scar of the axilla. Postoperative histopathology includes 17 cases of adenomatous hyperplasia, six cases of cyst, and two cases of follicular adenoma. For all cases hospitalization period was two days. Conclusion：Thyroidectomy via axillary approach under operating microscope has a good cosmetic advantage without a post-operative scar of the anterior neck. The procedure is simple due to direct vision using operating microscope, easy to identify important structures by magnifying them, and therefore surgical time can be reduced.

The specialized structure of the upper eyelid ensures complete closure of the eye and eyeball sealing. An upper eyelid injury can cause various symptoms associated with eyeball trauma, not just scar formation or eyelid deformity. In this report, we describe a case of lagophthalmos observed after wound repair in a patient with a crushing injury caused by a grinder. Several surgical techniques are used to treat lagophthalmos or scar contracture. In most cases, a releasing procedure is performed after 6 months of initial repair. However, if the patient has severe symptoms that are not relieved by conservative care, early revision is inevitable. We describe a case of early lagophthalmos successfully resolved with pentagonal wedge resection, fat redistribution, and full-thickness skin grafting. After the revisional surgery, we observed that the patient regained the ability to completely close the injured eyelid, with restoration of function and favorable cosmetic outcomes. Pentagonal wedge resection to release a retracted structure, fat redistribution to prevent readhesion, and full-thickness skin grafting for enough amount of skin to regain upper eyelid function is useful for scar release and lagophthalmos following crushing injuries of the upper eyelid.

Background Recently, the number of thyroid surgery cases has been increasing; consequently, the number of patients who visit plastic surgery departments with a chief complaint of swallowing deformity has also increased. We performed a scar correction technique on post-thyroidectomy swallowing deformity via platysma flap with Z-plasty and obtained satisfactory aesthetic and functional outcomes. Methods The authors performed operations upon 18 patients who presented a definitive retraction on the swallowing mechanism as an objective sign of swallowing deformity, or throat or neck discomfort on swallowing mechanism such as sensation of throat traction as a subjective sign after thyoridectomy from January 2009 till June 2012. The scar tissue that adhered to the subcutaneous tissue layer was completely excised. A platysma flap as mobile interference was applied to remove the continuity of the scar adhesion, and additionally, Z-plasty for prevention of midline platysma banding was performed. Results The follow-up results of the 18 patients indicated that the definitive retraction on the swallowing mechanism was completely removed. Throat or neck discomfort on the swallowing mechanism such as sensation of throat traction also was alleviated in all 18 patients. When preoperative and postoperative Vancouver scar scales were compared to each other, the scale had decreased significantly after surgery (P<0.05). Conclusions Our simple surgical method involved the formation of a platysma flap with Z-plasty as mobile interference for the correction of post-thyroidectomy swallowing deformity. This method resulted in aesthetically and functionally satisfying outcomes.

Endometriosis is defined as the presence of functioning endometrial tissue outside the uterine cavity, and the standard treatment is extensive surgical excision. Cesarean scar endometriosis is a type of cutaneous endometriosis arising on or near a Cesarean section scar. A 44-year-old woman presented with a $9{\times}6$ cm sized dark-brown, stony-hard, irregular, lower abdominal mass of four years duration. The patient had a history of two Cesarean deliveries, 14 and 16 years ago. Suspecting endometriosis, we excised the tumor conservatively rather than extensively to prevent incisional hernia considering the benign nature of the tumor and the low possibility of recurrence because the patient's age was near menopause, along with simultaneous bilateral salpingo-oophorectomy that was performed in this case. On reconstruction, mini-abdominoplasty was adopted to avoid possible wound complications and cosmetic deformities. The patient was satisfied with the cosmetic results, and neither recurrence nor functional problems occurred during the 1-year follow-up period. Plastic surgeons should keep in mind the possibility of cutaneous endometriosis in an abdominal mass of a female of reproductive age with a previous history of pelvic or intra-abdominal surgery. An optimal result from oncological, functional, and cosmetic standpoints can be achieved with conservative excision followed by mini-abdominoplasty of extensive Cesarean scar endometriosis.

Background Hypertrophic scars and keloids are associated with abnormal levels of growth factors. Silicone gel sheets are effective in treating and preventing hypertrophic scars and keloids. There has been no report on the change in growth factors in the scar tissue following the use of silicone gel sheeting for scar prevention. A prospective controlled trial was performed to evaluate whether growth factors are altered by the application of a silicone gel sheet on a fresh surgical scar. Methods Four of seven enrolled patients completed the study. Transforming growth factor (TGF)-${\beta}1$, platelet-derived growth factor (PDGF), and basic fibroblast growth factor (bFGF) were investigated immunohistochemically in biopsies taken from five scars at 4 months following surgery. Results In both the epidermis and the dermis, the expression of TGF-${\beta}1$ (P=0.042 and P=0.042) and PDGF (P=0.043 and P=0.042) was significantly lower in the case of silicone gel sheet-treated scars than in the case of untreated scars. The expression of bFGF in the dermis was significantly higher in the case of silicone gel sheet-treated scars than in the case of untreated scars (P=0.042), but in the epidermis, the expression of bFGF showed no significant difference between the groups (P=0.655). Conclusions The levels of TGF-${\beta}1$, PDGF, and bFGF are altered by the silicone gel sheet treatment, which might be one of the mechanisms of action in scar prevention.

Purpose: Heterotopic calcification is the abnormal deposition of calcium salts in tissues other than bone and enamel, and it occurs in the form of dystrophic calcification or metastatic calcification. This deposition can occur under many conditions, but in some rare cases, it may develop in burns and nonhealed scars. It is difficult to treat the combination of heterotopic calcification and ulceration in scar tissues by using conservative therapy and to determine the margin of excision in such cases. Our study proposes the use of intraoperative C-arm-guided mapping of lesions with heterotopic calcification, and adequate excision of ulcers in chronic scars where heterotopic calcification is also observed. Methods: This study included 2 patients and was conducted from January 2010 to July 2010. The first patient was a 63-year-old woman who presented with atypical calcium deposits and chronic ulceration in the lower one-third region of the right leg. The second patient was a 38-year-old man who presented with a nonhealing ulcer that had developed on the right leg 3 months earlier he had a history of 40% scalding burns on the entire body. Surgery is the most reliable method for treating heterotopic calcification therefore, both patients were treated using intraoperative C-arm-guided marginal mapping of heterotopic calcification, followed by release of contracture, and eventually split-thickness skin grafting. Results: Plain radiographs of the leg showed spotty radiopaque areas in the hard part of the scar well superficial to the underlying bones. Histopathological analysis revealed multiple foci of calcified deposits, increased fibrosis, and inflammation in the scar tissue. Surgery-related complications were not observed. Conclusion: C-arm guided excision of calcified scars and the release of contracture can cure nonhealing ulcers and may therefore prevent recalcification.
