Purpose: Autologous fat injection is ideal for patients who wish to add contour, projection and gross volumization of the aging, atrophic face and is claimed to be a safe procedure. However, there are several case reports in the literature where patients have suffered from acute visual loss and cerebral infarction after facial fat injection. This paper will explore a rare case of vessel related complication, an arteriovenous fistula that occurs after fat injection on forehead. Method: A 28 - year - old female who showed a non - tender, soft $1.0{\times}2.5cm$ sized mass on forehead for 3 weeks. A thrill could be detected on the totuous dilatated vessel - like structure around the mass. She had a fat injection on forehead for soft tissue augmentation 3 months prior to developing the mass. 3 - dimensional brain CT angiography showed arteriovenous fistula. Results: The fistula is totally excised with ligation of feeding vessels. Pathology report showed an atypical vessel which had intimal thickening, myxoid degeneration and thrombus formation. There were no evidences of recurrence at least for 2 months of follow - up. Conclusion: An occurrence of arteriovenous fistula after autologous fat injection is very rare. After perforation of artery and vein by coincidence, blood extravasates with the formation of a hematoma capsule and a pseudocapsule around it. The hematoma capsule would expand and clot would reabsorb resulting in a cavity leading to fistula formation. Other vessel related complications like acute visual loss or cerebral infarction are very severe. Therefore, surgeons should be cautious during facial fat injection to avoid vessel injuries.

Background The aim of this investigation was to systematically review the current literature to provide the best data for indications, outcomes, survival, and complication rates of pedicled propeller perforator flaps for upper body defects. Methods A comprehensive literature review for articles published from January 1991 to December 2011 was performed using the PubMed, Medline, and Cochrane Databases. Articles without available full-text, single case reports or papers with excessive missing data were excluded. Papers reporting pedicle-perforator (propeller) flaps used for lower extremity reconstruction were excluded from meta-analysis. Results From the initial 1,736 studies our search yielded, 343 studies qualified for the second stage of selection. Of 117 full-text reports screened, 41 studies, met the definitive inclusion and exclusion criteria. Of the selected 41 articles, 26 were case series, original papers or retrospective reviews and were included, whereas 15 were case report papers and therefore were excluded. Two hundred ninety-five propeller flaps were reported to have been used in a total of 283 patients. Indications include repair of trauma-induced injuries, post-trauma revision surgery, cancer resection, chronic infection, pressure sores, and chronic ulcers with a major complication rate (3.3%) comparable to that of free flaps. No specific exclusion criteria for the procedure were presented in the studies reviewed. Conclusions Pedicled propeller flaps are a versatile and safe reconstructive option that are easy and quick to raise and that provide unlimited clinical solutions because of the theoretical possibility of harvesting them based on any perforator chosen among those classified in the body.

With the gradual increase of cases using fillers, cases of patients treated by non-medical professionals or inexperienced physicians resulting in complications are also increasing. We herein report 2 patients who experienced acute complications after receiving filler injections and were successfully treated with adipose-derived stem cell (ADSCs) therapy. Case 1 was a 23-year-old female patient who received a filler (Restylane) injection in her forehead, glabella, and nose by a non-medical professional. The day after her injection, inflammation was observed with a $3{\times}3cm$ skin necrosis. Case 2 was a 30-year-old woman who received a filler injection of hyaluronic acid gel (Juvederm) on her nasal dorsum and tip at a private clinic. She developed erythema and swelling in the filler-injected area A solution containing ADSCs harvested from each patient's abdominal subcutaneous tissue was injected into the lesion at the subcutaneous and dermis levels. The wounds healed without additional treatment. With continuous follow-up, both patients experienced only fine linear scars 6 months postoperatively. By using adipose-derived stem cells, we successfully treated the acute complications of skin necrosis after the filler injection, resulting in much less scarring, and more satisfactory results were achieved not only in wound healing, but also in esthetics.

Cystadenocarcinoma of the salivary gland is a rare malignant tumor. It was first defined as papillary cystadenocarcinoma in the 1991 World Health Organization (WHO) classification, and it was reclassified as cystadenocarcinoma in the 2005 WHO classification. It is a low-grade neoplasm that features slow growing and predominantly cystic growth. We report a case of cystadenocarcinoma occurring on the parotid gland of a 61-year-old female patient presenting palpable mass on her left cheek. Preoperative examination may not reveal typical malignant characteristics. Such as in our case, the differential diagnosis between cystadenocarcinoma and benign lesion is difficult occasionally. We discuss the clinical and histopathological features of cystadenocarcinoma with the review of the literature.

Purpose: Tarsal tunnel syndrome is characterized by pain and paresthesia of the entire posterior tibial nerve and its branches of the lower extremity. The cause of the tarsal tunnel syndrome is usually unknown but, rare case of space occupying benign tumors such as a ganglion may be one of the causes. We report our experiences of surgical treatment of the tarsal tunnel syndrome caused by ganglion we have encountered recently. Methods: A 54-year-old male patient presented with paresthesia, burning pain, positive Tinnel's sign without preceeding trauma, infection or any other causes of event. With surgical intervention, we completely removed the space occupying ganglion and with performed surgical release of the posterior tibial nerve and its branches. Results: At a 14-month follow up examination, the symptoms of paresthesia, burning pain, sensory disturbance was much improved compared to the preoperative conditions. Takakura's rating scale was elevated from 4(Poor) to 8(Good). Conclusion: We report our surgical experience of a rare case of tarsal tunnel syndrome caused by a ganglion, with a review of literature.

In case of deep excavation analysis, the theory of beam on elasto-plastic geo-material (elasto-plastic theory) can not consider the inclined ground layers appropriately. It is frequently assumed that the soil layers are parallel to the surface. However, the soil layers are generally inclined and even asymmetric. The common modelling of the asymmetric half section of the excavation system using the elasto-plastic theory, can lead differences from the real behaviour of ground, which has critical significance in case of deep excavation in urban area. In this study, an attempt to find appropriate modelling methods was made by carrying out a comparative study between the FEM and the elasto-plastic analyses. It is shown that in case of the upward-inclined soil profile the elasto-plastic theory may underestimate the performance of retaining structures.

Cleft palate and congenital alveolar synechia is a rare syndrome. Only eight cases have been previously reported. It consists of a spectrum of facial anomalies always including cleft palate and congenital alveolar synechiae without other abnormalities. This report described an unusual case of congenital alveolar synechial band spanning posterior alveolar of the two jaws with cleft palate. Previously reported cases showed bilaterally or anteriorly located fibrous band. In our department, a new born revealed unilateral posterior synechia. Under brief intravenous sedation, synechium was divided using bipolar diathermy in the nursery at 3 days of age because of poor feeding. This division allowed full jaw opening after brief passive exercise. The patient is growing and maturing as expected with no complications. This patient is supposed to be the first reported case of isolated unilateral alveolar synechium combined with cleft palate in the worldwide.

Purpose: Glomus tumor is a benign neoplasm of the normal glomus body, occurring as painful subcutaneous nodules, frequently located in the subungual area. There are few cases of facial glomus tumor reported and we report a case of glomus tumor developing on the columella of nose. Methods: A 68-year-old female presented with a mass of the columella grown for 2 years. The nodule was 0.6 cm in diameter, red-colored without any symptoms such as pain, tenderness and cold hypersensitivity. The pathologic result after punch biopsy was hemangiopericytoma. Excision with local anesthesia was executed. Results: The postoperative recovery of the patient was uneventful, Histopathological examination indicated a glomus tumor. Immunostaining revealed positivity for vimentin, actin, and negativity for desmin, CD-34. After 8 months follow up, there is neither complication nor evidence of local recurrence on clinical examination. Conclusion: To accomplish an accurate diagnosis of glomus tumor, the histopathological examination is essential together with immunochemical studies. The differential diagnosis include hemangioma, lipoma, epidermal inclusion cyst, dermoid cyst and arteriovenous malformation in this region. We report a case of glomus tumor on the face with uncommon clinical features.

Objectives : In traditional Korean medicine literature, Succium(琥珀) is known to be effective in eliminating edema. However, pumpkins are misused in folk remedies to manage edema, because succium and pumpkin is homophony to 'Hobak' in Korean. The purpose of this study is to report the effects of Succium decoction on two patients with edema after plastic surgery. Methods : We treated two patients with edema after plastic surgery using Succium decoction. Numeric rating scale (NRS) of edema, photograph of changes in edema before and after treatment were analyzed to evaluate the effects of treatment. Results : After 2 weeks of administration, NRS for facial edema decreased from 5 to 3 and 2 to 1, respectively. Photograph of edema decreased after treatment, and there were no adverse events. Conclusions : This case report suggests that Succium decoction can be effective in treating edema after plastic surgery.
