Full-thickness nasal tip reconstruction is a challenging process that requires provision of ample skin and soft tissue, and intricate cartilage structure that maintains its architecture in the long term. In this report, we describe reconstruction of a full-thickness nasal tip and ala defect using a posterior auricular artery perforator based chondrocutaneous free flap. The flap consisted of two lay ers of skin covering conchal cartilage, and was based on a perforating branch of the posterior auricular artery. A superficial vein was secured at the posterior margin. The donor perforator was anastomosed to a perforating branch of the lateral nasal artery. The superficial vein was connected to a superficial vein of the surrounding soft tissue. The donor healed well after primary closure. The flap survived without complications, and the contour of the nasal rim was sustained at follow-up 6 months later. As opposed to combined composite reconstructions using a free cartilage graft together with a small free flap or pedicled nasolabial flap, the posterior auricular artery perforator free flap encompasses all required tissue types, and is similar in contour to the alar area. This flap is a useful option in single-stage reconstruction of nasal composite defects.

Persistent lymphocele of the groin is a complication of groin surgery that can severely impact the quality of life. The restoration of the interrupted lymphatic pathway is considered by many authors the ideal treatment to prevent a recurrence. However, multiple aspiration procedures and surgical revisions can compromise the availability of local veins needed for a lymphovenular bypass surgery. In addition, surgical debridement of a long-standing lymphocele can generate extensive dead space and contour deformity. A flap delivering additional venules for trans-flap lymphovenular anastomoses (LVAs) can overcome both problems by providing soft tissue and competent veins harvested outside the zone of injury. A successful case of severe groin lymphocele treated with trans-flap LVAs from an abdominal-based flap is presented. The patient was referred to us for a recurrent lymphocele developed in the right groin after lipoma excision that persisted despite multiple surgical attempts. After the identification of patent and draining inguinal lymphatic vessels, a pinch test was used to design a mini-abdominoplasty superficial inferior epigastric artery flap. The superficial veins of the cranial incision were identified and anastomosed to the lymphatic vessels after the pedicled flap harvested and insetted in the groin. The early restoration of lymphatic drainage and the optimal aesthetic outcome supports the combined approach offered by trans-flap LVAs as a valuable therapeutic option for severe and persistent lymphocele.

Purpose: In the 1990s, skin island flap supplied by the vascular axis of the sensitive superficial nerves had been introduced. For example, neurocutaneous flaps supplied by the vascular axis of the sural nerve and saphenous nerve have been used. But the flap supplied by the vascular axis of superficial peroneal nerve has not been used commonly. Because there have been few anatomical reports about the superficial peroneal nerve accessory artery(SPNAA), we could not apply the neurocutaneous flap supplied by SPNAA. The aim of this study is to investigate the anatomy of SPNAA, number and location of its perforators, and septocutaneous perforators from the anterior tibial artery in anterior intermuscular septum. Methods: So, we dissected a total of eight cadavers. Measurements were made of the positions of the dissected arteries and perforators from the head of the fibula. Results: In all cadavers the superior lateral peroneal artery was originated from the anterior tibial artery and contributed SPNAA. Arising from the anterior tibial artery an average of 5.63 cm inferior to the fibular head, it varied from 10 cm to 16 cm in length. SPNAA gave off an average of 4.38 perforators to supply lateral aspect. In one case the inferior lateral peroneal artery was present and arose from the anterior tibial artery 18 cm inferior to the fibular head. There were an average of 3.38 direct septocutaneous perforators from the anterior tibial artery. Conclusion: Septocutaneous perforators from SPNAA mainly exist from proximal 1/6 to 3/5 of lower leg. In the distal 1/3 of lower leg where the accessory artery was disappeared, exist mainly direct septocutaneous perforators from the anterior tibial artery. Our results can be helpful to applications of the neurocutaneous flap using SPNAA or fasciocutaneous flap based on direct septocutaneous perforators.

This study identified the loss of minimum fluidization velocity and pressure in accordance with the superficial velocity of $NiO/MoO_3/MoS_2$, a rare metallic oxide and high value-added material in the lab-scale fluidized bed reactor (L=0.25 m, D=0.05 m). The average pressure loss in L/D 1, 2, and 3 of $NiO/MoO_3/MoS_2$ within the scope of superficial gas velocity between 0.07 and 0.45 m/s based on the L/D 1, 2, and 3 of the specimen was shown to be 290~1952 Pa at decreasing flux and 253~1925 Pa at increasing flux. The comparison between the theoretical value proposed by Wen and the test data showed a difference between 0.021~0.36 magnification. Based on these results, this study was able to determine the operation conditions where rare metallic oxides could be applied in real phenomena.

Many reports have been published on complications related to middle cerebral artery (MCA) aneurysm surgical clipping procedures. We report an emergency intracranial in situ bypass surgery case which was performed as a rescue procedure after aneurysmal neck laceration during clipping of an MCA large aneurysm. In this case, we performed in situ M3-superficial temporal artery (STA) interposition graft-M3 bypass procedure. If a STA-MCA anastomosis is not available under MCA flow obstruction, we can consider an emergency in situ MCA-MCA bypass procedure with or without an STA interposition graft.

The superficial femoral artery (SFA) is a relatively rare location for lower limb aneurysmatic disease. In the literature, this disease is described an association between a relatively high growth rate and/or the rupture of aneurysms and chemotherapeutic agents. We report a case of the rupture of a giant SFA aneurysm in a patient during chemotherapy for acute lymphatic leukemia.

During coronary artery bypass surgery, there are several discrete maneuvers that facilitates localization of the invisible left anterior descending coronary artery. In some cases with intramyocardial left anterior descending artery, long-term patency of a bypassed graft may depend on anastomosing the internal mammary artery graft to the more proximal and superficial site of the intramyocardial left anterior descending artery. We describe an easy technique to locate the proximal superficial left anterior descending artery with a distal coronary arteriotomy and retrograde insertion of a coronary probe.

This study was done with 105 cases of dermatomycosis of dermatological patients who had visited the dermatology clinic in Taejon city. Of dermatophytosis, the decreasing orders of clinical location by the incidence were Tinea pedis (44.8%), Tinea cruris (30.5 %) and Tinea corporis (10.5%). The organisms identified from dermatophytoses were 6 genus: the decreasing orders of frequency were Trichophyton spp. (43.5%), Candida spp. (12.9%), Microsporium spp. (3.2%) and Epdermophyton flocosum(1.6%). The most common causative organisms was Trichophyton spp.
