The feasibility and possible effects of palatal soft-tissue expansion in palatal repair were studied. A prospective longitudinal animal experiment was performed in 75 growing cats assigned to 5 groups. In 31 cats, a midline defect was made, and bipediced flaps were raised at the age of 8 weeks (stimulated Langenbeck operation) in order to create palatal scars. At the age of 14 weeks, custom-mad...

RM Zucker, M Sapijaszko. Latex allergy in association with tissue expansion. Can J Plast Surg 1995;3(3):163-165. This case report outlines the sequence of events in an intraoperative anaphylactic reaction as the pockets for tissue expanders were bing developed. Previous expansion had been carried out uneventfully suggesting previous sensitization. Subsequent testing revealed significant latex a...

BACKGROUND Wound healing complications can occur after calvarial vault expansion due to tension on the scalp flaps. OBJECTIVES To compare wound healing outcomes in patients with craniosynostosis undergoing calvarial vault expansion with and without intraoperative tissue expansion of the scalp. METHODS The present analysis was an institutional review board-approved, retrospective cohort stud...

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 ...

The goal of this manuscript is to establish a novel computational model for skin to characterize its constitutive behavior when stretched within and beyond its physiological limits. Within the physiological regime, skin displays a reversible, highly nonlinear, stretch locking, and anisotropic behavior. We model these characteristics using a transversely isotropic chain network model composed of...

Living tissues undergo deformation during morphogenesis. In this process, cells generate mechanical forces that drive the coordinated cell motion and shape changes. Recent advances in experimental and theoretical techniques have enabled in situ measurement of the mechanical forces, but the characterization of mechanical properties that determine how these forces quantitatively affect tissue def...

Skin expansion is one of the major developments in reconstructive surgery. The use of tissue expansion has been popularized among plastic surgeons and has become the treatment method of choice for many congenital and acquired defects in a wide variety of diseases in adults and then later in children. The authors analyze their clinical experience in the treatment of burn scars and complex defect...
