Abstract:

<p><strong>Background:</strong> Cholesteatoma is a serious health hazard which can give rise to alarming intracranial and extracranial complications as it can progressively enlarge and invade into neighbouring structures. Thus, early diagnosis and prompt management of a suspected cholesteatoma is necessary. High resolution computed tomography (HRCT) temporal bone scan clearly defines the extent and location of soft tissue density in middle ear with adjoining bony erosions. The aim of the study was to determine the role of HRCT temporal bone in early detection of cholesteatoma

Introduction: Accurate preoperative imaging of the temporal bone in patients receiving cochlear implants is important. High resolution computed tomography (HRCT) and magnetic resonance (MR) imaging are the 2 preoperative imaging modalities that provide critical information on abnormalities of the otic capsule, pneumatisation of the mastoid, middle ear abnormalities, cochlear ducts patency and presence of cochlear nerve. Materials and Methods: The HRCT and MR imaging in 46 cochlear implant patients in our department were reviewed. Results: Majority of our patients [34 patients (73.9%)] showed n

BACKGROUND Chronic otitis media (COM) of squamosal type is associated with cholestatoma with potential complications. Clinical examination and high resolution computed tomography (HRCT) scans are necessary to assess the disease site and extension. The purpose of the study was to compare the preoperative HRCT findings with the intraoperative surgical findings in squamosal type of chronic otitis media as well as various parameters in HRCT temporal bone and intraoperative findings.

Abstract:

BACKGROUND The complicated middle and inner ear anatomy challenge the diagnostic ease in radiological evaluation of the temporal bone. Their tiny dimension and close neighbouring of the structures limited the successful imaging facilities for long periods of time. Conventional radiological procedures have been inadequate for diagnostic imaging but recently multidirectional tomography and high-resolution computed tomography (HRCT) has gained importance. Inflammatory and infectious diseases of the temporal bone are a major indication to perform highresolution CT. Such studies allow one to evalua

High-resolution computed tomography (HRCT) has been the radiologic test of choice to evaluate the facial nerve. The necessary HRCT projections, slices, and enhancement techniques to visualize each segment have been outlined. We have developed a radiologic protocol that uses MRI in conjunction with HRCT, applying the strengths of each to evaluate the facial nerve. We have evaluated 15 patients and have found that MRI is
