Differential diagnosis of NLCS includes nevus sebaceous, skin tag or fibroepithelial polyp, neurofibroma, lymphangioma, lipofibroma, focal dermal hypoplasia (Goltz syndrome), lipomatosis, and Michelin tire baby syndrome.[2,4] Histopathological examination helps in the differentiation. There is absence of fat cells in the dermis in skin tag. In lipofibroma skin, appendages are absent in the derm...
Autogenic fat graft usually suffers from degeneration and volume shrinkage in volume reconstruction applications. How to maintain graft viability and graft volume is an essential consideration in reconstruction therapies. In this presented investigation, a new fat graft transplantation method was developed aiming to improve long term graft viability and volume reconstruction effect by incorpora...
OBJECTIVE We investigated the use of autologous platelet-rich plasma (PRP) to improve the success rate of fat graft myringoplasty in perforated tympanic membranes of rats. MATERIALS AND METHODS A total of 20 healthy Wistar albino female rats were divided into two groups. In Group 1, the left tympanic membranes were perforated and grafted with a fat graft that was harvested from the inguinal r...
Figure 1. Patient presenting at age 6 after several surgical attempts at closure. She has unstable skin graft over allogenic dermis graft. A 6-year-old girl had undergone multiple operations for an omphalocele but still retains a very large ventral hernia. She presented with an eventrated abdomen with unstable, scarred closure (see Fig. 1). A reconstruction using intermuscular tissue expanders ...
BACKGROUND AND OBJECTIVES In theory, infrared vibrational bands could be used for selective photothermolysis of lipid-rich tissues such as fat, sebaceous glands, or atherosclerotic plaques. STUDY DESIGN/MATERIALS AND METHODS Absorption spectra of human fat were measured, identifying promising bands near 1,210 and 1,720 nm. Photothermal excitation of porcine fat and dermis were measured with a...
CONCLUSION: In both groups, fat grafting for pedal atrophy positively impacted pain and function. These measures demonstrated a persistent improvement, though fat volume returned to baseline. This finding may be attributed to the observed increase in dermal thickness. Together, these results suggest that fat grafting may thicken or stabilize the dermis, contributing to improved clinical outcome...
Skin image segmentation semi-automatic algorithm for highfrequency ultrasound probes with 75 MHz has been designed. The method includes a specific image filtering procedure followed by multiframe active contour algorithm to detect borders between the epidermis and the dermis and between the dermis and subcutaneous fat tissue.
