The anatomical structure of the murine nasal cavity was resolved by x-ray computer tomography and the data sets of the CT-scans were used to construct anatomical prototypes that were manufactured by 3D-printing, stereolithography or vacuum moulding. In the present study we show the successful construction of such anatomical 3D models and their use to establish intranasal application techniques under 3R criteria to minimize the use of laboratory animals.}, year = {2018}, journal = {Berliner und Münchener Tierärztliche Wochenschrift}, volume = {131}, month = {06/2018}, publisher = {Schlütersche Verlagsgesellschaft mbH & Co.
