Lentigo maligna melanoma and lentigo maligna are typically located on photo-exposed sites such as the head and neck, with the cheek being the most common site. Since lentigo maligna melanoma and lentigo maligna are found predominantly on such cosmetically-sensitive areas, it is critical to determine the exact histologic margin for maximal sparing of tissue and complete extirpation of the tumor. Since Mohs micrographic surgery has been recommended for tumors on cosmetically-sensitive locations where the tumor margin is indistinct, it appears to be a reasonable treatment modality for this type of tumor. We describe a case of lentigo maligna melanoma on the cheek, which was resected with Mohs micrographic surgery.

PURPOSE: Human adipose tissue-derived mesenchymal stem cells(hATSCs) can be differentiated into multiple mesenchymal lineages, including bone, cartilage, and muscle. And growth hormone play important roles in the normal growth and development of the CNS. In this study, we explored whether the transplanted hATSCs and growth hormones could improve functional recoveries from rats with contusive spinal cord injury. METHODS: We divided 30 female rats, which were subjected to a weight driven implant spinal cord injury, into 3 groups with 10 rats each; Group A as a control group, group B with hATSCs transplantation on injured region, and group C with hATSCs transplantation and GH administration for 7 days. Then, we researched their neurologic functional recoveries before and 2, 4, and 8 weeks after transplantation using Basso-Beattie-Bresnahan (BBB) locomotor rating scale. And we checked Y- chromosome positive cells by FISH(Fluorescent in situ hybridization) to identify the survival of transplanted mesenchymal stem cells. RESULTS: After 4 weeks of transplantation, the group B and group C showed significant improvement of neurologic function on BBB locomotor rating scale in comparison with the group A(Group A: 13.1+/-0.58, Group B: 14.6+/-0.69, Group C: 14.9+/-0.56). Moreover, the group C displayed meaningful recovery of neurologic function after 8 weeks in comparison with group B (Group B: 15.7+/-0.63, Group C: 16.5+/-1.14). The group A, the control one, improved for 5 weeks after injury, and had no more recovery. On the other hand, Group B and C showed the improvement of neurologic function continuously for 9 weeks after injury. CONCLUSION: In this study, we found out that hATSCs transplantation have an effect on neurologic functional recovery of spinal cord injured rat and GH injection seems to bring the synergistic results on this good tendency.

PURPOSE: Until now, many kinds of treatment modalities for facial bone fractures have been proposed. Among them, the semi-rigid fixation using miniplates has become the most popular procedure due to its simplicity and good clinical results. However, achieving anatomic reduction of bone fragments with miniplates may be difficult because of inadequate instrumentation for fracture fragment stabilization. We examined the use of inter-maxillary fixation screws or titanium screws tied with stainless steel wire to assist in positioning of fractured segment. METHODS: We used this method for reduction in 50 cases of facial bone fractures. Inter-maxillary fixation screws or titanium screws tied with stainless steel wire were used to assist in aligning bony segment. Postoperative radiologic and clinical follow-ups were performed. RESULTS: Radiologic follow-up showed correct reduction and fixation in all cases. Nonnunion and malunion were not shown. Clinical follow-up showed an satisfactory results. CONCLUSION: By using Inter-maxillary fixation screws tied with stainless steel wire, it was shown that reducing the bony segment to their preinjury position is easy to perform and it enables us to make more accurate reduction, ensure wider visual field.

Journal of the Korean Cleft Palate-Craniofacial Association 2010;11(1):13-18
PURPOSE: Nasal defect can be caused by excision of tumor, trauma, inflammation from foreign body reaction. Nose is located in the middle of face and protruded, reconstruction should be done in harmony with size, shape, color, and textures. We report various methods of nasal reconstruction using local flaps. METHODS: From March 1998 to July 2008, 36 patients were operated to reconstruct the nasal defects. Causes of the nasal defects were tumor(18 cases), trauma(11 cases), inflammation from foreign body reaction(5 cases) and congenital malformation(2 cases). The sites of the defects were ala(22 cases), nasal tip(8 cases) and dorsum(6 cases). The thickness of the defects was skin only(5 cases), dermis and cartilagenous layer(7 cases) and full-thickness(24 cases). According to the sites and thickness of the defects, various local flaps were used. Most of alar defects were covered by nasolabial flaps or bilobed flaps and the majority of dorsal and tip defects were covered by paramedian forehead flaps. Small defects below 0.25cm2 were covered with composite graft or full-thickness skin graft. RESULTS: The follow-up period was 14 months. Partial flap necrosis was observed in a case, and one case of infection was reported, it was improved by wound revision and antibiotics. Nasal reconstruction with various local flaps could provide satisfactory results in terms of color and texture match. CONCLUSION: The important factors of nasal reconstruction are the shape of reconstructed nose, color, and texture. Nasolabial flap is appropriate method for alar or columellar reconstruction and nasolabial island flap is suitable for tip defect. The defect located lateral wall could be reconstructed with bilobed flap for natural color and texture. Skin graft should be considered when the defect could not afford to be covered by adjacent local flap. And entire nasal defect or large defect could be reconstructed by paramedian forehead flap.

PURPOSE: Transgender is a disorder of gender identity, who have appropriate chromosomal, hormonal and anatomical characteristics corresponding to their sexual phenotype but feel strongly with respect to their sexual identity, that they belong to the opposite sex. There is a persistence discomfort and sense of inappropriateness about one's assigned sex in a person who has reached puberty. Transgender is a psychiatric problem, but surgical method provides more satisfactory adjustment for patients. In gender reassignment surgery for female to male transgender, mastectomy, nipple reduction, hysterectomy, oophorectomy and phalloplasty are included. And as the final operation, recommended for scrotoplasty and artificial testes insertion. So we investigated the necessity and method of scrotoplasty in the final operation of female to male transgender. METHODS: The authors have long term follow-up of 75 cases female to male transgender from January 1991 to February 2008. Among them, 13 cases were evaluated in this study. During phalloplasty, the labium major skin preserved. And this labium majoral skin flap was made for the neoscrotum. At least six months later, artificial testes were inserted in neoscrotum with local anesthesia. Middle sized(3cm diameter) artificial testes(silicon gel or carving soft silicone implant) were used because of the limitation of the neoscrotum. We evaluated the questionnaire and interview about the postoperative satisfaction in configuration of reconstructed scrotum, and the necessity of operation, the postoperative psychosocioeconomic improvement and limitation of body exposure activities such as swimming, public bathing. RESULTS: Based on this study, satisfaction of reconstructed scrotum after scrotoplasty was improved(92%). The necessity of scrotoplasty was in 92.3% and the postoperative psychosocioeconomic well-being improvement was 77% in answers. Less limitation of activities requiring body exposure was 54% in answers. Most of the patients were satisfied with the results of surgical operation despite of some postoperative complications. CONCLUSION: This study reports that the scrotoplasty in female to male transgender is not only a conversion of external genitalia but also an improvement of psychosocial state. As most of the patients sincerely hope to take this operation, we improve our surgical method for more good results.

PURPOSE: The survival of bone marrow derived stem cell was reported several times. But the survival of adipose tissue derived stem cells(hASCs) was not mentioned on. We studied the adipose tissue derived stem cell's survival and effect on articular cartilage in rabbits. METHODS: Osteoarthritis was induced in twenty New Zealand white rabbits by intraarticular injection of monosodium iodoacetate(MIA). After four weeks, hASCs were also injected into the knee joints space without any vehicle, but the control group received phosphate buffered saline only. The histologic grade of articular cartilage was measured in 4 and 8 weeks after the transplantation of hASC and the viability of injected stem cells measured by Fluorescent in situ Hybridization (FISH) examination. RESULTS: After 4 and 8 weeks from hASCs transplantation, histologic grade was not significantly difference between two groups(p>0.05), and the Y chromosome of the transplanted hASCs was not detected in articular cartilage. CONCLUSION: We found that direct injection of hASC in joint space didn't work on damaged articular cartilage repair.

INTRODUCTION: Most of the palatal fistulas develop along the suture line in a small size, so they can be corrected easily by re-palatoplasty or various flap surgery using the local mucoperiosteum. But it is very difficult to repair if the fistula is very large or located anterior to the hard palate. Buccal mucosal or vestibular mucosal flaps may settle the problems but there are many limitations on the size and location. And other extraoral distant flaps need not only many surgical steps but also cause inconvenience. But tongue flap proffers as an excellent method for the repair of large anterior palatal fistula because of highly mobility and rich blood supply and low donor site morbidity. MATERIALS & METHODS: We treated the six cases of large palatal fistulas using the distally based tongue flap. We dissected under the submucosa layer around fistula site preserving the mucoperiosteum and the elevated flap was rotated to nasal side and sutured with 4-0 Vicryl(R) for the repair of the nasal side. And then we elevated the tongue flap on the distal portion of the tongue. The elevated tongue flap was placed on the defect area and sutured with 4-0 Chromic(R). After 2 or 3 weeks, we detached the tongue flap which was placed on the fistula site. Donor site was closed with 4-0 Chromic(R). RESULTS: The mean size of palatal fistula was 7.2 cm. All of patients complained the discomforts in masticating and speaking before flap detaching operation. A wound dehiscence was observed on tongue flap sutured to defect site. But it was healed by revisionary suture. There was no donor site complication. CONCLUSION: The authors propose that the distally based tongue flap is an excellent method for the repair of large palatal fistula because of its highly mobility, rich blood supply, and few of donor site morbidit
