Comparative evaluation of the Komodo Dragon (Varanus komodoensis) and the green Iguana (Iguana iguana) skull by three-dimensional computed tomographic reconstruction

Abstract

The purpose of this paper was to do a comparative evaluation of the skull of two species of lizards, the Komodo dragon (Varanus komodoensis) and the Green Iguana ( Iguana iguana), by three-dimensional computed tomographic reconstruction. Images provided by this method give excellent anatomic detail of the skull. Therefore, essential differences in the configuration of the orbit and the lateral bones of the neurocranium were visualized in lateral and dorsal reconstructed images. The images obtained by tridimensional computed tomographic reconstruction can be a valuable diagnostic aid for the clinical evaluation of several head disturbances in lizards.

Namen prispevka je bil s tridimenzionalno računalniško tomografsko rekonstrukcijo opraviti primerjalno oceno lobanje dveh vrst kuščarjev, komodoškega varana (Varanus komodoensis) in zelenega legvana (Iguana iguana). Slike, pridobljene s to metodo, prikažejo odlične anatomske podrobnosti lobanje. Zato so bile na stranskih in dorzalnih rekonstrukcijah slik vidne bistvene razlike v zgradbi orbitalnega področja in stranskih kosti nevrokranija med obema vrstama kuščarjev. Slike, pridobljene s tridimenzionalno računalniško tomografsko rekonstrukcijo, so lahko dragocena diagnostična pomoč pri klinični oceni večih napak glave pri kuščarjih.
