In the subject of this case report, a self-inflating hydrogel expander was implanted as a treatment for posttraumatic enophthalmos in a fully sighted eye. The intervention caused hypertropia with diplopia, restriction of eye movements, visual field defects, and colour desaturation as a result of excessive swelling of the expander. Once the expander volume was adjusted, clinical signs regressed, and the aesthetic results were excellent. Following the implantation of self-inflating orbit expanders, it is advisable to carry out immediate follow-up during the expander's swelling period, and long-term follow-up is also advised to rule out late sequelae, as a position-dependent secondary glaucoma could occur.

Hydrogels are currently widely used in regenerative medicine and wound repair due to their superior biocompatibility, reliable mechanical strength, and good morphological memory. We aimed to prepare a self-expanding hydrogel that can be used as a skin expander for the repair of large soft skin tissue defects. Self-expanding hydrogels were prepared by chemical cross-linking, which consisted of water-soluble chitosan (CS), acrylamide (AM), methylene bisacrylamide (NMBA), etc.

Article Synopsis
- Self-inflating hydrogel expanders are effective in treating congenital anophthalmia and blind microphthalmia, resulting in significant increases in palpebral fissure height and length.
- A review of 161 patient records revealed a few complications, including expander migration, but these were rare and manageable with further surgical interventions.
- Patients with a relative axial length of less than 0.5 are more likely to require additional expansion procedures after initial treatment.
Soft tissue expansion using self-inflating osmotic hydrogel expanders prior to bone augmentation: healing and complications. Evidence-based review.

Aim: This review aims to assess complication rates, soft tissue gain, and bone gain associated with the use of self-inflating osmotic hydrogel tissue expanders (SOHTEs) for soft tissue expansion (STE).
Methods: A comprehensive search on Pubmed and Google Scholar databases was conducted to identify human studies using SOHTEs for STE; last searched in March 2023. Expansion phase details and expander variables were documented.
Hydrogel based soft tissue expanders for orodental reconstruction.

Tension-free flap closure to prevent soft tissue dehiscence is a prerequisite for successful bone augmentation in orodental reconstructive surgery. Since soft tissue contour follows the underlying jaw bony architecture, resorption of alveolar (jaw) bone limits the availability of soft tissue for wound closure following major bone reconstruction, required to facilitate oral rehabilitation with endosseous dental implants following tooth loss. Although there are several clinical procedures to increase soft tissue volume, these techniques are complicated and technically demanding.

One of the greatest challenges for ocularists is prosthetic fitting in children, especially in children with congenital anomalies such as clinical anophthalmia or functionless (blind) microphthalmia. The most frequent reason for prosthetic fitting in children is a condition following enucleation for retinoblastoma, followed by trauma and congenital pathologies. The standard treatment after enucleation or evisceration begins intraoperatively with the selection of an suitable implant and the use of a conformer at the end of the operation to shape the prosthetic cavity.
