It will be able to differentiate the infection/inflammation from the cholesteatoma and it will show the status of the membranous labyrinth. However, in case of suspected infection/inflammation and/or complications such as fistulisation to the lateral semicircular canal, MRI including delayed post-gadolinium T1-weighted sequences and non-echo planar diffusion-weighted (non-EP DWI) sequences is required. Facial nerve canal and lateral semicircular canal integrity can be evaluated as well. It will be able to demonstrate ossicular and epitympanic erosion and will nicely show tegmen delineation. In case of a clear-cut clinical and otoscopical image of a cholesteatoma, CT will do as primary and sole imaging technique prior to first-stage surgery. Moderate intensity on T2-weighted images, clearly lower than the hyperintensity of inflammation. Lack of enhancement on post-gadolinium T1-weighted sequences Information obtained this way, when combined with imaging findings, provides an accurate and trustworthy diagnosis, allows avoiding misinterpretation and ensures appropriate treatment. Usually, patients with temporal bone pathology first undergo clinical examination, often with audiology tests. Also, in non-inflammatory conditions of external and middle ear computed tomography (CT) or magnetic resonance imaging (MRI) would provide a diagnosis and/or necessary information for surgery in a significant number of cases. Therefore, especially in complicated and recurrent conditions, imaging plays an important role imaging findings may fundamentally influence the treatment. However, the prevalence of ear infections increased significantly between 19, and this may suggest that the current approach to preventing and treating middle ear inflammation is not adequate. In the majority of these cases, proper diagnosis is made by clinical examination alone and patients will not benefit from additional diagnostic imaging studies. In children and teenagers, inflammatory conditions of the middle ear are the most frequent reasons to prescribe antibiotics and perform surgery. Pathology of the external and middle ear is the third most common reason of visiting a general practitioner or a family doctor.
