Purpose: To close anterior cranial base, various types of pedicle flaps have been developed previously. However, the results of those pedicle flaps were not constant. To solve such problem, the author designed bipedicle temporalispericranial (BTP) flap based on various types of existing flaps and this study intends to introduce this flap and present clinical application case. Methods: The pedicle of the proposed temporalispericranial flap is temporalis muscle. The point of this BTP flap is that because of both sides of the unilateral temporalispericranial flap are connected by midline pericranial tissue connected with dense vascular network communicate one another locally, that BTP flap can be safely elevated. The case is a 14 months old male patient of frontoethmoidal encephalomeningocele. Surgery was done in a way that after elevating BTP flap and removing encephalomeningocele, BTP flap was moved intracranially, and to prevent cerebrospinal fluid leakage, anterior cranial base was closed. Results: During 1 year and 6 month outpatient tracking observation, no particular finding like CSF leakage, meningitis or hydrocephalus was observed. Conclusion: The benchmarked BTP flap, effective in the treatment of frontoethmoidal encephalomeningocele, is one of the methods to close intracranium and extracranium.

A 22-year-old man is presented with 3 months' history of dull pain on the lower thoracic area. Imaging studies suggested osteoid osteoma of 11th thoracic spine, which was verified pathologically after en bloc resection through transfacetal approach. The patient's preoperative pain was resolved immediately. We emphasize the importance of early diagnosis and complete surgical excision of tumor nidus.

Moyamoya disease is defined as the development of collateral pathways, associated with bilateral chronic progressive stenosis of the carotid fork. Persistent trigeminal artery is the vessel most frequently observed to persist into adult life among persistent carotid-basilar and carotid-vertebral anastomotic vessels. The authors present a man who had a sudden, severe headache and brain CT showed subarachnoid hemorrhage in left interpeduncular and prepontine cistern. Four-vessel angiogram revealed moyamoya disease associated with aneurysm arising from the junction of persistent trigeminal artery aneurysm and basilar artery. As a treatment, coil embolization was tried but it was failed because of anatomical difficulty of aneurysm. The aneurysm was successfully treated with clipping surgery 10 days later. To our knowledge, this is the first case being reported.
Congenital Dermatofibrosarcoma Protuberans: A Case Report
윤병민,Yun, Byung-Min Korean Society of Plastic and Reconstructive Surge 2010 Archives of Plastic Surgery Vol.37 No.3
Purpose: Dermatofibrosarcoma protuberans is a rare tumor, accounting for 0.1% of all malignant tumors. Although metastasis is very uncommon, local recurrence occur frequently. Dermatofibrosarcoma protuberans occurring in children is even more rare; this is the first case report of congenital dermatofibrosarcoma protuberans in Korea. Methods: The patient is a 14-month-old male infant with a lesion that was first thought to be a birthmark. The lesion grew larger, and a punch biopsy revealed dermatofibrosarcoma protuberans. A wide local excision was performed with a 2 cm peripheral resection margin beyond the gross tumor lesion. Deep fascia and a portion of muscle underneath the central part of the lesion were also taken. The surgical defect was covered by a split-thickness skin graft. Results: There has been no clinical sign of recurrence over one year after the surgery. Conclusion: A patient with congenital dermatofibrosarcoma protuberans detected at an early stage underwent a wide local excision of the tumor after accurate diagnosis was carried out by biopsy and immunohistochemical studies. There was no clinical evidence of tumor recurrence during over a 1-year follow-up.

Loupes-assisted microsurgery often needs an operational head lamp for a better condition of light. This may cause serious neck fatigue due to the weight the operational head lamp, the limitation of the operator's head movement from the hind cable, and some cost for purchasing and management of it. On the contrary, a mountain head lamp is very light, full of freedom in movement, applicable to all types of loupes, and relatively very cheap. In conclusion, a mountain head lame can be a cost-effective light source for Loupes-assisted microsurgery.

In this paper, robust watermarking scheme which is supposed to embedded watermark incorporating fuzzy inference into transform-based watermarking is proposed. In order to select optimal sub-bands, fuzzy inference method is involved, and human visual properties, such as text degree, contrast sensitivity function are utilized as a fuzzy input function. So as to testify the proposed scheme, such attacks as JPEG, filtering, cropping are used. Experimental results showed that DWT-based approach is superior to DCT with respect to the JPEG and AWGN ahannel in the OFDM/QPSK system, whereas DCT is more efficient in cropping attack at 2~5%.
Non-Melanocytic Skin Cancers of the Head and Neck: A Clinical Study in Jeju Province
강재경,윤병민,송정국,신명수 대한성형외과학회 2017 Archives of Plastic Surgery Vol.44 No.4
Background Jeju Island is geographically and socioeconomically distinct from the mainland of South Korea. Thus, the presentation and management of non-melanocytic skin cancers (NMSC) of the head and neck may differ from those in other regions of the country. We compared the clinical characteristics and treatment modalities of NMSC on Jeju Island with the findings of similar regional studies. Methods Patient data, including age, sex, diagnosis, tumor site, treatment, and recurrence, were obtained from the medical and pathology records of patients diagnosed with NMSC between January 2010 and June 2015. Results In total, 190 patients (57 men) with a mean age of 75 years (range, 42–97) were assessed. Overall, 203 NMSCs were diagnosed, including 123 basal cell carcinomas and 80 squamous cell carcinomas. The tumor sites included the nose, cheeks, periorbital area, and lips (n=55, 54, 25, and 20, respectively). We identified 92 T1-stage and 60 T2-stage tumors, and 120 cases were treated with wide surgical resection and 17 cases were treated with radiation therapy at the medical center. Of the 120 cases treated surgically, 69 required reconstructive surgery using a local skin flap, 22 required full-thickness skin grafting, and 12 underwent primary closure. Basal and squamous cell carcinomas recurred in 2 and 1 cases, respectively. Conclusions Compared to the reports from other regions, the average patient age was 10 years higher, with a marked female preponderance. While the proportion of squamous cell carcinoma was higher than in other regions, the tumor distribution and surgical management profiles were similar.

There are many women who want larger and brighter eyes that will give a favorable impression. Surgical methods that make the eye larger and brighter include double eyelidplasty, epicanthoplasty, as well as lateral canthoplasty. Double eyelidplasty produces changes in the vertical dimension of the eyes, whereas epicanthoplasty and lateral canthoplasty create changes in the horizontal dimension of the eyes. Epicanthoplasty, a surgical procedure which enlarges the eye horizontally, is performed at the inner corner of the eye, whereas lateral canthoplasty enlarges the outer edge of the eye. In particular, if the slant of the palpebral fissure is raised and the horizontal dimension of the palpebral fissure is short, adjusting the slant of the palpebral fissure through lateral canthoplasty can achieve an enlargement of eye width and smoother features. Depending on the patient’s condition, even better results can be achieved if this procedure is performed in conjunction with other procedures, such as double eyelidplasty, epicanthoplasty, eye roll formation surgery, fat graft, and facial bone contouring surgery. In this paper, the authors will introduce in detail their surgical method for a cosmetic lateral canthoplasty that lengthens the lateral canthal angle and corrects the outer tail of the eyes, in order to ease the unfavorable impression.
