NihalPublication Metadata only Benign Chondroid Syringoma: Atypical Presentation of a Rare Eccrine Tumor(ELSEVIER SCIENCE INC, 2011) TEZEL, ERDEM; Sirinoglu, Hakan; Ersoy, Burak; Tezel, ErdemChondroid syringoma is a rare eccrine tumor that is often benign but has the potential for malignant transformation and distant metastasis. Histopathological analysis may not be definitive, and any patient with atypical features, an accelerated clinical course, or high suspicion for malignant transformation is a candidate for immediate surgical intervention and close follow-up. The purpose of this article is to review the clinical features of this rare tumor with a special emphasis on its atypical presentation. (C) 2011 by the American College of Foot and Ankle Surgeons.

Although various techniques for ear reduction and helical rim reconstruction have been reported in the literature, an ideal method is yet to be defined. Double helical rim advancement flaps with scaphal resection presented in this report represent a practical technique for correcting macrotia and reconstructing helical rim defects. The amount of full-thickness resection at the helical rim is planned according to the desired reduction or extent of tumor. After helical excision, an incision that transects all the layers of the ear is carried out along the helical sulcus inferiorly and superiorly to yield two advancement flaps. Using scissors, a crescent from the scapha is excised through the full thickness of the ear. The flaps are approximated and sutured to the scapha by means of stitches that pass through skin and cartilage. The described technique has been performed successfully since 1998. It has been used for 12 cases of macrotia, 28 cases of tumor surgery, and 7 cases of ear reduction for asymmetric ears. No major complications have been encountered. Three cases are reported as examples of the procedure. Double helical rim advancement flaps with scaphal resection represent a versatile and safe technique that can be used for ear reduction, helical rim reconstruction, and correction for discrepancy in size of ears.Publication Metadata only The effects of the size of liposuction cannula on adipocyte survival and the optimum temperature for fat graft storage: an experimental study(ELSEVIER SCI LTD, 2009) TEZEL, ERDEM; Erdim, Melike; Tezel, Erdem; Numanoglu, Ayhan; Sav, AydinBackground: Determining the most advantageous size of liposuction cannula and injection needles in terms of adipocyte viability could help to increase fat graft survival. When recurrent injections are necessary, storing fat tissue which is harvested during the first operation could be a practical solution if it is stored at an appropriate temperature providing the highest amount of viable fat cells. Methods: Fat tissue was removed from the abdomen of 10 consecutive female patients by 6-, 4- and 2-mm-diameter liposuction cannulas. Fat tissue harvested with the 6 mm cannula was injected through 14, 16 and 20 g needles and collected in separate tubes. An additional three tubes of fat samples were prepared from fat tissue obtained with the 6 mm cannula to be stored at +4, -20 and -80 degrees C for 2 weeks. Viability of the fat grafts was evaluated by fat cell isolation with collagenase digestion and staining with supravital dye and counting adipocytes with a haemocytometer. Results: The viability of fat grafts harvested with the 6 mm cannula was higher than grafts obtained with smaller cannulas. The viability of fat grafts injected through 14, 16 and 20 g needles were similar to each other. The viability of fat grafts stored at +4 degrees C was similar to fresh tissue whereas freezing fat grafts caused significant toss of viable adipocytes compared to fresh tissue. Conclusions: The use of larger liposuction cannulas for fat tissue harvesting provides more viable fat grafts. A temperature of +4 degrees C could be proposed as an effective and easily available way of storing fat grafts for at least 2 weeks.
