Anti-scarring medical gel for sinus surgery

Sinus sufferers around the world could benefit from a new gel, which prevents scarring after surgery. The wound dressing, which improves healing, controls bleeding and prevents adhesions (scars that can form at the surgical site) following sinus surgery, is the brainchild of an international team of medical researchers. Derived from a polymer named chitosan and extracted from crab shell and squid, the gel has been successfully trialled in sheep and humans over the past four years. It is s expected to benefit millions of people around the world who undergo endoscopic surgery for blocked sinuses.
