Measured dimensions for the tube of heathland sheep and blackface sheep.

<p>Due to the small width at the isthmus, reliable measurements of the height of the silicone models were not feasible.</p><p>Min and max values (spread) are given instead of the standard deviation. The p-values refer to the respective comparison between DVT data and the silicone model. DVT – digital volume tomography. ET – Eustachian tube.</p><p>Measured dimensions for the tube of heathland sheep and blackface sheep.
