A simple autologous fibrinogen glue for otologic surgery

Area of Science:

• Biomaterials Science
• Surgical Innovation
• Hematology

Background:

• Autologous fibrinogen concentrates are crucial for developing effective tissue adhesives.
• Current methods may have limitations in accessibility or viral safety.
• Otologic surgery requires specialized hemostatic and sealing agents.

Purpose of the Study:

• To present a simple, hospital-laboratory-adaptable method for concentrating autologous fibrinogen.
• To detail the preparation and application of an autologous fibrinogen-thrombin tissue glue for otologic surgery.
• To highlight the safety benefits of using autologous materials, preventing viral transmission.

Main Methods:

• Modification of the standard cryoprecipitate technique for fibrinogen concentration.
• Preparation of a coagulum-type tissue glue using patient's fibrinogen, thrombin, and calcium.
• Application of the autologous tissue glue in otologic surgical procedures.

Main Results:

• The described method allows for easy concentration of autologous fibrinogen in a standard hospital lab.
• The resulting autologous fibrinogen-thrombin glue is effective for otologic surgery applications.
• Use of autologous fibrinogen completely mitigates the risk of transmitting hepatitis or AIDS viruses.

Conclusions:

• A simple and safe method for preparing autologous fibrinogen concentrate for tissue glue is established.
• This technique offers a practical solution for otologic surgery, enhancing patient safety by eliminating viral transmission risks.
• The presented approach provides valuable insights for the preparation and utilization of autologous tissue glues.
