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: Varicella-zoster virus (VZV) infection is a common childhood disease. However, old and immune compromised patients are also at risk. Necrotizing fasciitis is a life threatening infection of the subcutaneous tissues, rapidly extending along the fascial planes. It is associated with a significant mortality rate, reported between 20% and 50%, and is therefore regarded as a surgical emergency. The authors treated a patient, who developed skin necrosis of her nose and left hemifacial area, following VZV infection. There are few literatures concerning this case; therefore, we present a rare case with review of literature. METHODS: A 39-year-old woman had shown a localized, painful, multiple bullae and eschar formation in her nose and left hemifacial area for several days. Her skin lesion had rapidly worsened in size and morphology. RESULTS: We diagnosed her as a necrotizing fasciitis, following herpes zoster, and then we performed a debridement of necrotic tissue and took a full thickness skin graft on her nose and left hemifacial area. Now, she was followed up with acceptable aesthetic result after 6 months. CONCLUSION: Secondary bacterial skin infection following VZV, can cause a result in a higher risk of complications. Among the complication, a necrotizing fasciitis of the head and neck is uncommon, and involvement of the nose is even more rare. Through this uncommon case report, we intend to emphasize the fact that early diagnosis of necrotizing fasciitis is very important, since it frequently necessitates surgical treatment which improves morbidity and leads to good recovery.

Thermal injury to free flap site can be severe and distressing injuries both for the patients and the surgeon. Thermal injuries to insensate free flaps are known complications often reported. But thermal injuries to free flaps are also occurred in the perioperative period. This study focused on the various factors associated with these injuries. We reported a 36-years old male patient with scalding burn in using warmed saline irrigation who underwent anterolateral thigh perforator free flap due to diabetic foot ulcer on dorsum of left foot. The clinical characteristics of thermal injuries during the free tissue transters are 1) Warmed saline irrigation is often too hot and a temperature excess 48degrees C should be considered very hot saline during the operation. 2) The direct exposure of the microscope light often causes iatrogenic burn, so copiously irrigating the surgical field and readjusting the light source's position or its output intensity are important. Surgeon must be aware that warmed saline irrigation & surgical microscope can cause thermal injury to free flap during the free tissue transfer.

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.

BACKGROUND: A recent advancement in microsurgery, the free flap is widely used in the reconstruction of the lower leg and foot. The simple and effective methods of local flaps, including transposition and advancement flaps, have been considered for patients with chronic debilitation who are unable to endure long surgical procedures or general anesthesia. However, the location and size of the wound may restrict the clinical application of a local flap. Under these circumstances, a sural flap can be an excellent alternative, rendering satisfying clinical outcomes in chronically debilitated patients. METHODS: Between 2008 and 2012, 39 patients underwent soft tissue defect treatment by sural artery flap as a final method. All of the patients had at least one chronic disease or more (diabetes, hypertension, vascular disease, etc.). Also, all of the patients had a history of chronic lower extremity ulceration, which revealed no response to several months of conservative treatment. RESULTS: The results of the 39 cases had a success rate of 100% with 39 complete recoveries. Nine cases suffered complications: partial necrosis (n=4), wound dehiscence without necrosis (n=3), hematoma (n=1), and infection (n=1). CONCLUSIONS: The sural artery flap is not only useful for the lower leg but also for the heel, and other various parts. Furthermore, it is a relatively simple surgical technique for reconstructing the defect area for patients with various chronic conditions with a high surgical risk or contraindications to surgery.

PURPOSE: Neurofibromas of neuroectodermal origin are commonly found in Von Recklinghausens disease or neurofibormatosis type 1. It is an autosomal dominant disease caused by mutation of the long arm of chromosome 17. It can present from small nodules to disfiguring giant tumor. Plexiform neurofibroma is benign in most cases, but it could be transformed into malignant tumor, which requires surgical excision. To cover the defects after the excision, a number of surgical correction methods are available. This study is to report a surgical correction of disfiguring plexiform neurofibroma using anterolateral thigh free flap for extensive defects after surgical excision of neurofibrona. METHODS: Data of five neurofibroma patients with an average age of 39 including medical history, physical examination, computed tomography, and magnetic resonance imaging were checked. No disease other than neurofibroma were detected. Biopsy on the excised tissues was performed. The follow-up period was 7 to 27 months. RESULTS: The average size of defects after complete excision of neurofibroma was 13x10~25x15cm. Defects were covered by anterolateral thigh free flap, while donor sites were covered by local flap, split thickness skin graft and regional flap. Throughout follow-up, there were no complication, relapse, or any abnormalities. CONCLUSION: Despite various surgical correction methods are applicable to defects after excision on disfiguring plexiform neurofibroma, coverage of massive defects is still challenging in plastic and reconstructive surgeon. We have made five successful cases of surgical correction of disfiguring plexiform neurofibroma using anterolateral thigh free flap.

Automobile airbags have been shown to reduce morbidity and mortality in the event of a vehicle crash; however, new problems have been identified. Among these problems, direct injury from the airbag itself has become a serious concern. This suggests that an airbag itself may not be safe. Burn injury from airbags accounts for about 7.8% of all injuries caused by vehicle crashes. There are three types of burn injuries from airbags: Thermal, chemical, and frictional. Moreover, there are three subtypes within the category of thermal airbag burn, as identified by Tsunetuki in 2003. Herein, we review a case of an airbag burn and report a unique burn case on ‘an upper extremity’, including both thermal and frictional burns.
