“…In parallel, Wiese and co-workers conducted research into poly(methyl methacrylate) (PMMA)-based hydrogels, which had an increased swelling ratio [13,15,16]. Further clinical applications were reported by Berge et al [17], who facilitated direct closure of a radial forearm flap donor defect, and by Ronert et al [18,19], who used the device for breast reconstruction after mastectomy and achieved coverage of a post-auricular defect following the excision of a large pigmented nevus. In 2007 Kobus published a preliminary report using selfinflating tissue expanders in two-stage cleft palate repair [20].…”

“… 6 , 7 Exposure of the bone grafts for vertical ridge augmentation, as shown in Figure 1 , is a major cause of prerestorative complications that range from significant volume reduction in the final healing stages to complete loss of the bone graft. 6 , 8 – 15 Osmotically controlled hydrogel tissue expanders (HTEs) have been shown to offer a promising new method, 16 applicable both for skin 17 – 20 and oral mucosa (for the purpose of bone grafting). 7 , 21 However, rapid expansion of an HTE can lead to ischemia and subsequent necrosis of the expanding skin or oral mucosa, leading to loss of the device and exposure of alveolar bone.…”

Background:There are few methods for expanding oral mucosa, and these often cause complications such as tissue necrosis and expander eruption. This study examines mucosal blood perfusion following insertion of a novel shapeable hydrogel tissue expander (HTE). The canine model used subgingival insertion of HTE following tooth extraction and alveolar bone reduction. The primary goal of this study was to gain understanding of epithelial perfusion and reparative responses of gingival mucosa during HTE expansion.Methods:Nine Beagle dogs underwent bilateral premolar maxillary and mandibular tooth extraction. Three to four months later, HTE-contoured inserts were implanted submucosally under the buccal surface of the alveolar ridge. After removal and following a 6- to 7-month period of healing, new HTE implants were inserted at the same sites. The area was assessed weekly for tissue perfusion and volume of expansion. Biopsies for histological analysis were performed at the time of expander removal.Results:Within 2 weeks following the second insertion, blood flow returned to baseline (defined as the values of perfusion measurements at the presurgery assessment) and remained normal until hydrogel full expansion and removal. Volume expansion analysis revealed that the hydrogel doubled in volume. Histological assessment showed no macrophage or inflammatory infiltration of the mucosa. No superficial fibrosis, decreased vascularity, or mucosal change was seen.Conclusion:Maintenance of adequate tissue perfusion is a clinically important aspect of tissue expander performance to reduce risk of device loss or injury to the patient, particularly for areas with a history of previous surgeries.

“…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.
