Plastination of human tissues is one of the techniques that involve preservation by replacing water and liquids with polymers which are subsequently hardened. Luminal cast plastinated specimens are not only suited for our routine anatomical teaching and serve as base images for animation, but also provide excellent source to understand the three dimensional anatomical structure and its variations. The present study is being done to create an awareness of the simple technique with very low cost in preparation of luminal cast plastinated specimens of trachea-bronchial tree using general purpose silicon sealants in sheep lungs. These specimens contribute to our teaching aids to understand the three dimensional concept of trachea- ronchial tree in lungs and also additional information to our existing knowledge to arrive at a diagnosis of various bronchopulmonary anomalies, before any surgical interventions.
