The microarchitecture of collagen fibers in preauricular dermis specimens that were obtained during two-phase rhytidectomy were visualized and recorded using the scanning electron microscope. Examination of photomicrographs revealed that both spatial arrangement and degree of convolution of the collagen fibers were completely different in the specimens of the two phases. The results are interpreted in terms of the viscoelastic properties of the skin.

UI	MeSH Term	Description	Entries
D008855	Microscopy, Electron, Scanning	Microscopy in which the object is examined directly by an electron beam scanning the specimen point-by-point. The image is constructed by detecting the products of specimen interactions that are projected above the plane of the sample, such as backscattered electrons. Although SCANNING TRANSMISSION ELECTRON MICROSCOPY also scans the specimen point by point with the electron beam, the image is constructed by detecting the electrons, or their interaction products that are transmitted through the sample plane, so that is a form of TRANSMISSION ELECTRON MICROSCOPY.
