About Chitogel

Enhance post-operative care and the patient experience

Chitogel is a global medical device company offering a leading edge wound healing gel for use in endoscopic sinus surgery.

Our first product to market, the Chitogel Endoscopic Sinus Surgery Kit, is currently distributed in the United States of America, Australia and New Zealand so far.

Optimising wound healing after sinus surgery is critical to achieving long term, positive patient outcomes. It requires a product that supports rapid and complete wound healing, minimises adhesions, preserves structural integrity and addresses patient comfort.

Chitogel is a clinically proven hydrogel, designed to meet these needs and improve the outcomes of endoscopic sinus surgeries. These outcomes are supported by 10+ years of research and clinical evidence, 18+ published studies and successful patient and surgeon testimonials.
