“…Sometimes MIP help in the delineation of the details of prostheses. Several authors have already shown for CT that anatomical structures of the middle ear can be better depicted by angulated MPR [20][21][22]. This knowledge can be transferred and applied in post-processing of CBCT data.…”

• Middle ear prostheses became more filigree, leading to poorer visibility on CT. • High spatial resolution and paraxial reconstructions are necessary requirements for imaging evaluation. • CBCT and MDCT can identify type and positioning of titanium prostheses. • Metal artefacts play a minor part in filigree titanium prostheses. • Regarding visualisation of prostheses details, cone beam CT aids the evaluation.

Virtual endoscopy of the middle ear

Virtual endoscopy is a computer-generated simulation of fiberoptic endoscopy, and its application to the study of the middle ear has been recently proposed. The need to represent the middle ear anatomy by means of virtual endoscopy arose from the increased interest of otolarygologists in transtympanic endoscopy. In fact, this imaging method allows the visualization of middle ear anatomy with high detail, but it is evasive and is essentially used for surgical guidance. Virtual endoscopy provides similar perspectives of the tympanic cavity but does not require the tympanic perforation. In the study of the middle ear, specific attention is given to the retroperitoneum. This region contains elevations of the medial wall (pyramidal eminence and ridge, styloid eminence and ridge, subiculum, ponticulus) and depressions (sinus tympani, posterior sinus tympani, facial sinus, fossula of Grivot, oval window fossula), which can be effectively displayed by virtual endoscopy. Virtual endoscopy is foreseen as a useful tool in preoperative management of patients who are candidates for middle ear surgery, since it can predict with high detail the patient's specific anatomy by imaging perspectives familiar to otosurgeons.

Twenty-six ears (of 25 patients) with congenital dysplasia of the external and middle ear were studied with two different types of imaging technologies in order to find out if it is possible to improve the anatomical overview of the dysplastic middle ears by combining the imaging methods. All the 26 ears were studied with computed tomography (CT), which gave cross-sectional images of the tympanic cavity. A fiberoptic video-endoscope (FVE) was introduced through the nose and via the Eustachian tube into the middle ear so that the topographic view of the anatomical structures of the middle ear could be visualized. Some structures were visualized better with FVE than with CT and vice versa. We concluded that the combined information obtained from these two imaging technologies provided a better understanding of the structural anatomy of a congenital dysplastic middle ear.
