1.The Alar Extension Graft for Retracted Ala.
Journal of the Korean Society of Plastic and Reconstructive Surgeons 2009;36(1):66-74
PURPOSE: The importance of the deformities in alar - columellar complex has been underestimated in Asian ethnic groups for the last few decades. Fortunately, with increasing familiarity of the open rhinoplasty techniques, the anatomic details of the nasal tip have been pointed up. Definitely, having an interest and demand for improving the sub-normal relationship between the alar rim and columella are indebted for such growing of knowledge about nasal tip anatomy. However, it is true that any single procedure is not settled as versatile and fully confident modality to correct the retracted notching of the alar rim. With this article, I would like to propose another useful option for treating retracted ala. METHODS: The authors have tried to correct alar rim retraction by means of: (1) Triangular onlay septal cartilage graft on the lower lateral cartilage with the medial end fixed to the anterior surface of the lateral crus(Alar extension graft), (2) Inserting lateral end of the alar extension graft to the vestibular skin pocket in the form of a finger-in-groove, (3) using the vestibular skin in the form of an advancement flap, and (4) using the soft shield graft to prevent possible visible step-off of the alar margin. RESULTS: The authors applied an alar extension graft to 16 patients in order to correct a retracted ala for the last 27 months (August 2003-October 2005). The distance from alar rim to long axis of nostril was improved to be within 2mm in all cases, and also the shape of the alar rim changed to a round form. Nostril asymmetry (6%) was observed in one case, temporary palpable step-off (18%) in three cases, temporary visible step-off (6%) in one case, and temporary paresthesia of the tip (25%) in four cases, respectively. CONCLUSION: The alar extension graft is simple and efficacious. It does not need donor sites other than the operative field, and its results are predictable. In particular, since it may give structural intensity to a weak lower lateral cartilage, it may be preferentially used for the correction of a retracted ala that arises from hypoplastic lower lateral cartilage. Moreover intensified lower lateral cartilage also improves the esthetic shape of lobule.

BACKGROUND: Skin cancer is divided into two categories, melanoma and nonmelanoma skin cancer, by its malignant potential. The former is prone to be metastatic and it often requires regional lymph node dissection and chemotherapy, while the latter is rarely metastatic with no need for such further treatment. We report here on the reconstruction methods after surgical removal of skin cancers, with excluding melanoma. OBJECTIVE: Our purpose was to analyze the reconstruction methods according to the location and size of the lesions after surgical removal of nonmelanoma skin cancers and we report on the clinical findings. METHODS: We analyzed 186 cases of nonmelanoma skin cancers that were treated Between January, 2000 and December, 2006 at the Department of Dermatology, Chonbuk University Hospital. The cases were analyzed according to the reconstruction methods for the defects after surgery, the gender ratio, the age range, the lesion site and the lesion size. RESULTS: The mean age of onset was 67.7 years old. The ratio of men to women was 1:1.02. The most common nonmelanoma skin cancer was basal cell carcinoma (66.7%), followed by squamous cell carcinoma (22.1%), and Bowen's disease (4.3%). The most common site of all the nonmelanoma skin cancers was the face (68.8%), followed by the trunk (7.5%) and scalp (6.5%). The most common reconstruction method was local flap (40.3%), followed by primary closure (38.7%), skin graft (18.8%) and secondary intention (2.2%). In terms of location, the most commonly used method was local flap for the face (50.0%) and primary closure for the trunk (53.3%), scalp (83.3%) and the upper (44.4%) and lower extremities (63.6%). According to the lesions' size, the most common method was flap for tumor between 10 mm and 30 mm in diameter (95.1%), primary closure for tumor less than 10 mm in diameter (66.7%) and graft for tumor greater than 30 mm in diameter (66.7%). CONCLUSION: We offer this data for the reconstruction methods of nonmelanoma skin cancers and their clinical findings in Korea.

PURPOSE: Owing to the improvement of microscope, microsurgery implements, and microsuture, finger replantation has made a considerable development. With high success rate of microsurgery in children, positive results have been reported from distal amputation. We report the patients demographics, methods, and results of the microsurgery performed in children in our hospital for the last 8 years. METHODS: From the medical records of 21 patients who had given the treatment in our hospital from January 2000 to December 2007, we analyzed patients' sex, age, operative method, and complication retrospectively. RESULTS: The number of male patients was twice as many as female, where most patients belong to the ages of five to ten years. Operative methods performed in this study included end-to-end anastomosis of artery and vein, vein graft, and epineurial suture. As a result, 19 out of 21 cases were successfully accomplished, and four of them went through the debridement of necrotic tissue due to the partial necrosis of the lesion. A one-year follow-up observation was made after surgery and most of them were almost fully recovered as in their previous state. CONCLUSION: The success rate of finger replantaion in children is continuously improving despite the difficulty of vessel anastomotic procedure, rehabilitation treatment and management after surgery. We report the satisfactory results of pediatric finger replantation technically and aesthetically.

PURPOSE: Self-inflicted wrist laceration is a common injury in the department of hand surgery. The aim of this study was to investigate the clinical characteristics and psychiatric features of self-inflicted wrist laceration using categorization according to wound severity. METHODS: We reviewed 71 patients from 2002 through 2012. All of the patients were grouped into four groups. Data regarding the following characteristics were collected: age, gender, size, structure involved, instruments used, history of previous self-inflicted injury, comorbidities in psychiatric and presentation of follow-up outpatient appointment to the department of plastic surgery and psychiatry. RESULTS: In these patients, approximately 64% of patients were female. About 80% of patients cut their wrist using a knife. And in grade 3-4 injury, percentage of glass injury was relatively high (22%), compared with other grades (3%). Unlike previous studies, patients in grade 3-4 tended to cut their wrist repeatedly. Focusing on psychiatric problems, approximately one quarter of patients had a previous history of self-infliction. In all patient groups, mood disorder was the most common disorder in patients who had a previous psychiatric disorder. But after operation, more than two thirds of patients had not visited department of psychiatry again. CONCLUSION: We identified some other differences among their characteristics. All patients in group also should be evaluated and surgically treated properly. A multidisciplinary approach is required for patients with wrist laceration due to self-injury in comparison to those with laceration due to other causes. Because many of them have previous self-injury experiences and psychiatric disease.

PURPOSE: Incidence of radiographic contrast media extravasation has increased owing to the escalating availability of contrast enhanced imaging. Potential complications of extravasation include localized swelling, itching sensation, hypesthesia, erythema, limitation of finger movement, compartment syndrome, skin sloughing, and necrosis. We describe clinical characteristics and treatment of computed tomography contrast media extravasation. METHODS: A retrospective chart review was performed on 26 consulted patients experiencing contrast extravasation, between January 2005 and December 2011. Age, signs, symptoms, types of contrast administered, volume of extravasation, treatment and patient outcomes were documented and evaluated, retrospectively. RESULTS: Extravasation of less than 100 mL occurred in 85%. Immediate surgical therapy was necessary in 23% of cases. There were no postoperative complications and it rendered excellent cosmetic outcomes. In 77% of cases, conservative management was recommended, such as elevation and immobilization of extremity, application of ice pack, and careful monitoring. CONCLUSION: Prevention is the most important for extravasation injuries. Diagnosis and treatment must be made on the spot in order to avoid severe soft tissue damage. Hand surgeons' decision on the necessity of surgical treatment within 6 hours is important in the prognosis of patients.

BACKGROUND: Chondroid syringoma is a rare benign tumor composed of epithelial and stromal elements. Studies of chondroid syringoma are lacking in Korea and controversy still exists regarding the stromal cell origins. OBJECTIVE: To investigate the clinicopathological and immunohistochemical characteristics of chondroid syringoma in Korea. METHODS: We included 23 patients who were diagnosed with chondroid syringoma. RESULTS: There was a predilection for males (M : F=2.3 : 1), and the mean patient age was 50.4+/-15.4 years (range 22~78 years), peaking in the forties. Of the 23 cases, 22 (95.7%) had it on the head and neck. There were 21 apocrine type cases and 2 eccrine type cases. Apocrine type cases showed decapitation secretion as well as follicular and sebaceous differentiations. Myxohyaline matrix was present in all cases, and in some cases, chondroid, lipomatous, and osseous metaplasias were also observed. In apocrine type cases, inner cell layers displaying tubuloglandular structures expressed cytokeratin, carcino-embryonic antigen, and epithelial membrane antigen, while outer cell layers expressed vimentin, S-100 protein, neuron-specific enolase, and smooth muscle actin. Stromal cell immunophenotypes were similar to those of the outer layer. CONCLUSION: Chondroid syringoma was most commonly observed on the head and neck in middle-aged males. The apocrine type was far more common than the eccrine type and showed various differentiating characteristics. The matrix may contain myxohyaline stroma with alterations, including chondroid, lipomatous, and osseous metaplasias. Our immunohistochemical study suggests that myoepithelial cells play an important role in the histogenesis of chondroid syringoma and matrix production.

PURPOSE: Marjolin's ulcer is rare but highly aggressive malignant cancer that is associated with chronic, nonhealing wounds such as burn wound. There are no confirmed effective protocols for treatment of this disease. This study was conducted to describe the clinical presentation and treatment modalities of Marjolin's ulcer in our hospital. METHODS: This was a retrospective study of Marjolin's ulcer. 20 cases were histologically confirmed malignant skin cancer seen at Chonbuk National University Hospital from January 2000 to December 2011. Data were retrieved from patients' medical records and photographs. RESULTS: The total 20 cases of Marjolin's ulcer were studied. Squamous cell carcinoma was the most common pathological type in 20 patients (100%). Lymph node metastasis at the time of diagnosis was recorded in 3 patient (15%). Wide excision was the most common surgical procedure performed in 17 patients (85%) of cases. The reconstruction modalities were various as free flap 3 patients (15%), skin graft 13 patients (65%), local advancement flap 2 patients (10%) and regional flap 1 patient (5%). Local recurrence was noted in 3 patients (15%) who had surgical treatment. And one patient (5%) expired in hospital. CONCLUSION: Marjolin's ulcer is an infrequent lesion. Unfortunately the diagnosis and treatment are often delayed. If the wound was histologically confirmed, aggressive excision and reconstruction is warranted in these highly malignant skin cancer. Early recognition and aggressive treatment of Marjolin's ulcers are essential to improve outcomes.

BACKGROUND: Dermatofibrosarcoma protuberans is a mesenchymal tumor of the skin of intermediate-grade which is a rare condition. The slow growing and aggressive invasion on local tissues are characteristic features of dermatofibrosarcoma protuberans. The treatment for dermatofibrosarcoma protuberans is mainly a surgical excision such as a wide excision and Mohs micrographic surgery. OBJECTIVE: The aim of this study was to compare the result of wide excision and Mohs micrographic surgery for the treatment of dermatofibrosarcoma protuberans at a single institution in Korea. METHODS: A retrospective review was done for 24 patients diagnosed with dermatofibrosarcoma protuberans and treated surgically from 1999 to 2010 at Chonbuk National University Hospital. Patient demographics, tumor features, surgical features, and recurrence during the follow-up period were evaluated. RESULTS: 13 patients were treated with wide excision, and 11 with Mohs micrographic surgery. There was no metastasis for all the cases. Mean operation time for the wide excision group was 83 minutes whereas 182 minutes for the Mohs micrographic surgery group, and it was a statistically significant difference. However, no significant difference was observed in post-operative defect size, advanced surgical repair and local recurrence in our study. CONCLUSION: We suggest that wide excision and Mohs micrographic surgery are both successful modalities for the surgical treatment of dermatofibrosarcoma protuberans. Hence, individualized patient and tumor characteristics should be concerned when determining the surgical options for dermatofibrosarcoma protuberans.
