a Non-anatomical resin drainage channels (arrows) created by CAD modelling extending medially from the tympanic segment of the facial nerve, and (b) at the superior aspect of the superior semicircular canal, seen on multiplanar reconstructed CT imaging. These channels are placed in locations to allow millifluidic post processing (see step: 3D printing and post processing) while not interfering with surgically important anatomical landmarks
