The natural choice for post-operative care

Chitogel’s unique ability to support wound healing is a direct result of its three main ingredients, all of which are derived from natural sources. These ingredients are:

Chitosan, Dextran & Glycerol.

Chitosan Succinamide

Chitosan is well-known for its haemostatic properties and to prevent scarring.3 3Chandra RK, Conley DB, Haines GK, 3rd, Kern RC. Long-term effects of FloSeal packing after endoscopic sinus surgery. American journal of rhinology. 2005;19(3):240-243.4 4Kokkevold PR, Lew DS, Ellis DG, Bertolami CN. The effect of chitosan on lingual haemostasis in rabbits. J Oral Maxillofac Sug 1991;49858-863. Chitosan is made from chitin, which is found in a large number of natural sources, including crustaceans, insects, annelids and molluscs.

Chitosan has been shown to prevent adhesions with multiple studies showing the efficacy in adhesion reduction.5 5 Costain DJ, Kennedy R, Ciona C, McAlister VC, Lee TD. Prevention of postsurgical adhesions with N, O-carboxymethyl chitosan: examination of the most efficacious preparation and the effect of N, O-carboxymethyl chitosan on postsurgical healing.

Clinical results show that where Chitogel has been used post surgery, compared to using no packing materials at 12 months post-surgery, patients experienced:1 1Ha T, Valentine R, Moratti S, Hanton L, Robinson S, Wormald P-J.

  • Significant ostial area improvement.
  • Reduction in incidence of oedema & granulation.
  • Reduction in adhesions.

A recent clinical study demonstrated the use of Chitogel following ESS reduces the rate of revision surgery, leading to health system efficiencies and cost savings.16 16Barber JM, Bouras G, Robinson GS and Robinson SR. Chitogel improves long-term health economic outcomes following endoscopic sinus surgery in severe chronic rhinosinusitis patients. Front. Health Serv. 2024;4:1196499.

Assuming a cohort of 100 patients, the use of Chitogel over a 2-year period can result in:
  • 32% reduction in revision surgeries.
  • 40 hours of surgical and theatre time savings.
  • NZ $753,000.00 in health system cost savings.
