BACKGROUND: Education in laser microsurgery is generally acquired under the supervision of an experienced surgeon. During training phases, however, increased complication rates may occur. Viable models for training are therefore important. METHODS: Larynx models should be anatomically accurate in size, form and texture, and be able to simulate normal as well as pathological findings. RESULTS: The main component is gelatin. Elasticity and thermal qualities can be modified by additives. We have been able to develop a synthetic larynx model for CO(2)-laser surgery that closely resembles the physical and tactile qualities of human tissue. Further modification of the material produced cutting characteristics for CO(2)-laser similar to human tissue. CONCLUSION: The new larynx model allows the simulation of typical surgical situations. Surgeons in training can practice even difficult surgical procedures at low costs and without putting patients at risk, before carrying out the procedure on patients.
