“…Isotropic tissue expanders have also been used in the surgical correction of nasal hypoplasia and in the field of dental reconstruction [21,22]. In two recently published clinical series using isotropic osmotic tissue expanders in a variety of predominantly scar revision procedures, the authors concluded that the devices should be used with a degree of caution on account of the high procedural complication rate, due, in part, to the uncontrolled rate of expansion [23,24].…”

“…This hydrogel expander absorbs body fluid, which leads to a gradual swelling of the device to a definite volume and size, thus stretching the overlaying skin and stimulating growth [2,3]. Similar devices have also been used in surgical reconstruction for burns, scars [4,5] and cleft palate [6]. More recently, anisotropic self-inflating hydrogel expanders have been introduced, where the direction of expansion could be controlled [2,3].…”

Mechanical properties of expanded skin tissue are different from normal skin, which is dependent mainly on the structural and functional integrity of dermal collagen fibrils. In the present study, mechanical properties and surface topography of both expanded and nonexpanded skin collagen fibrils were evaluated. Anisotropic controlled rate self-inflating tissue expanders were placed beneath the skin of sheep's forelimbs. The tissue expanders gradually increased in height and reached equilibrium in 2 weeks. They were left in situ for another 2 weeks before explantation. Expanded and normal skin samples were surgically harvested from the sheep (n = 5). Young's modulus and surface topography of collagen fibrils were measured using an atomic force microscope. A surface topographic scan showed organized hierarchical structural levels: collagen molecules, fibrils and fibers. No significant difference was detected for the D-banding pattern: 63.5 ± 2.6 nm (normal skin) and 63.7 ± 2.7 nm (expanded skin). Fibrils from expanded tissues consisted of loosely packed collagen fibrils and the width of the fibrils was significantly narrower compared to those from normal skin: 153.9 ± 25.3 and 106.7 ± 28.5 nm, respectively. Young's modulus of the collagen fibrils in the expanded and normal skin was not statistically significant: 46.5 ± 19.4 and 35.2 ± 27.0 MPa, respectively. In conclusion, the anisotropic controlled rate self-inflating tissue expander produced a loosely packed collagen network and the fibrils exhibited similar D-banding characteristics as the control group in a sheep model. However, the fibrils from the expanded skin were significantly narrower. The stiffness of the fibrils from the expanded skin was higher but it was not statistically different.

“…In the classical expander's regular injections of the expanders is a difficult part for the children. The self-inflating expanders are a good choice for the problems [14,15]. After planning for the local tissue transfer, the expanders are inserted by a small incision at the margin of the nevi into the expanding area and allowed for the wound healing in its normal way.…”

Congenital hairy nevi or giant congenital melanocytic nevi (GCMN) especially that of the face pose a great challenge to reconstructive surgeons. These unsightly lesions can be psychologically damaging to both parent and child. A variety of treatment options exist for the management of such cases. In this review article, we present two children who had a GCMN of their face managed with self-inflatable tissue expanders (osmotic tissue expanders [OTEs]) for single stage excision, and reconstruction is presented. The uses of self-inflating tissue expanders are now a regular choice for tissue cover in wide areas and in children.
