Tissue Expansion - an overview | ScienceDirect Topics
The rate of expansion is limited by the relaxation and growth of the tissue overlying the expander. Pain and palpable tightness over the expander are clinical indicators that guide the rate of expansion. The patient is ready for the second surgical procedure when the expanded tissue is adequate to produce the desired effect. If the flap is to be advanced, it must be measured to …

10/07/2021·In some tissues, expansion rate does not balance cell production rate, so that individual cell size decreases even though total tissue size increases, for instance during early embryo development (Yoshida et al., 2014) or in the subapical region of growing root tips (Erickson & Sax, 1956; Moreno-Ortega et al., 2017). Cells may also divide without any …

19/08/2020·As a result of this robust edge motion, the areal expansion rate of the tissue is dictated by its perimeter-to-area ratio. To further emphasize the decoupling of the boundary and internal dynamics of epithelia, consider that the key findings in Figure 1 neither predict nor depend upon the radically different internal dynamics we observed within ‘small’ and ‘large’ tissues.
Retrospective analysis of tissue expansion in ...
Tissue expansion is a widespread and accepted concept in reconstructive surgery, but is also afflicted with a variety of complications. In burn patients, this technique allows large areas of burn scar to be replaced by tissue of similar texture and colour to the defect. We retrospectively reviewed our results with tissue expanders in 57 burn patients over a period of 8 years …

Tissue Expansion and Scar Revision - Dr. Shady Hayek
Tissue expansion generally produces excellent results when reconstructing some areas of the face and neck, the hands, arms, and legs. Expansion offers a near-perfect match of color, texture, and hair-bearing qualities. Because the skin remains connected to the donor area’s blood and nerve supply, there is a smaller risk that it will die. In addition, because the skin doesn’t …
