Self-inflating Tissue Expanders for Plastic Surgery, Ophthalmology and Dental

For the treatment of alopecia at a 4 year old child, tissue was gained with an osmed tissue expander Rectangle 300 ml. Picture 1 shows implanted expander after expansion. Picture 2: Expander has been removed and defect has been covered with gained skin.
Osmosis expanders are stable, dry devices, made of a crosslinked, physiological well tolerated hydrogel. Physical absorption of body fluid conducts an increase of volume (3 to 12 times depending on the indication) and an expansion of the tissue. The gained tissue can be used for defect coverage or the hollow space for the insertion of implants.

Due to the hydrogel’s material properties all forms and sizes are possible. The variety of forms and a continuous growth allow further treatments than with conventional expanders. Especially small expanders have opened new opportunities in the fields of ophthalmology (anophthalmus), plastic surgery (breast reconstruction, tubular breast, Alopecia, cleft palate, naevi, reconstruction of small and big deformities, scars, skin cancer and more) and dental (prior to augmentation of edentulous ridge).

Until now, more than 10.000 hydrogel expanders and implants have been used by surgeons worldwide. Very low complication rates (significantly smaller than 5%, while conventional expanders have a complication rate over 20%) and material advantages indicate that osmotic expanders and implants have the potential to succeed also in further applications. There are 45 publications about self-inflating tissue expanders.

Advantages: short surgical time, less pain, no injection needed, no pressure peaks, local anesthesia possible, minimal invasive, each size and shape is possible, new indications especially for children.

osmed tissue expanders are specially developed for indications in the fields of ophthalmology, plastic surgery and dental. osmed tissue expanders are offered in 8 forms each with different sizes: Round, Rectangle, Ellipsoid, Cylinder, Cupola, Pin, Sphere and Hemisphere.
