Plastination is a technique to preserve the dissected specimens. In luminal cast plastination technique, internal structures of specimens having lumen such as tracheobronchial tree, blood vessels and bony labyrinth are studied by filling with silicone or resin. Objective: To observe the branching pattern of tracheobronchial tree of ovisaries using luminal silicone cast plastination technique. Materials and Method: Fresh five specimens of ovisaries trachea and lung were collected from slaughter

Results: Out of 5 specimens, one specimen showed the presence of an additional bronchus on right side. In other specimens, trachea bifurcates into two primary or principal bronchi and then to secondary and tertiary bronchi. Conclusion: Plastinated specimens are easy to handle compared with formalin preserved specimens. The cast obtained by this technique can be used for teaching purpose as well as can be exhibited in the museum which reveals the fine intricate structure of the organ.
