“…Our study confirmed that CT is substantially reliable in the determination of the status of the ossicular chain. These results are in concordance with other studies [8,11,14,15,19,21]. Pre-operative knowledge of the status of the ossicular chain would allow the surgeon to be ready for ossicular chain reconstruction and to better advise the patient on the degree of hearing attainable after surgery.…”

Chronic suppurative otitis media (CSOM) presents with a typical history of recurrent otorrhoea with tympanic membrane perforation. The diagnosis of cholesteatoma is usually made on otologic examination. High resolution computed tomography (HRCT) is indicated to evaluate the extension and the complications of cholesteatoma. The aim of the work was to study the role of HRCT in detecting, evaluating diagnosing and managing CSOM. All patients presenting with CSOM who were planned for mastoid exploration surgery in department of ENT, Gauhati Medical College and Hospital within a period of 2 years-from 1st January, 2013 to 31th December, 2014, were taken up for the study. HRCT mastoids done routinely before cholesteatoma surgery, but with improved resolution, to characterize all middle ear structures and complications of the disease prior to surgery, might guide as road map during mastoid explorations for unsafe CSOM. The important role of HRCT lies on the early detection of cholesteatoma, and more conservative surgical procedures can be used to eradicate the disease.

“…Due to its anatomically close proximity to the medial wall of the attic, the lateral semicircular canal is the most frequently eroded. 1 , 4 , 10 , 11 However, a false impression of the canal fistula may be encountered. Thus, axial CT sections must be reinforced by coronal images for evidence of cortical thinning.…”

“…Middle ear cholesteatoma, which is more often acquired than congenital, has been recognized clinically and radiologically for many years. 1 , 2 , 3 Acquired cholesteatoma is the main complication of chronic otitis, resulting from ingrowth of the keratinizing squamous epithelium, from the external acoustic meatus to the middle ear through the tympanic membrane. 1 , 3 The hallmarks of cholesteatoma are a soft tissue mass-like opacity in the middle ear cavity and mastoid antrum associated with smooth bony erosion of the ossicles and expansion of adjacent structures.…”

BACKGROUNDHigh resolution computerized tomography (HRCT) is valuable for detection of early erosive changes suggestive of cholesteatoma. The aim of our study was to determine characteristic CT findings in patients with middle ear cholesteatoma.METHODSWe conducted a retrospective review of CT scans and surgical and histopathological reports in 64 patients with middle ear cholesteatoma (35 male, 29 female; age range, 7–80 years, median age, 22 years). CT scans were evaluated for the presence of intra-tympanic non-dependent soft tissue density, the extent of middle ear involvement, bone expansion and thinning, and bone erosions involving the ossicles and adjacent structures.RESULTSMiddle ear cholesteatoma was more common in male patients and in patients aged 20–35 years. All patients had soft tissue density in the middle ear. Fifty-nine (92%) had expansion of the aditus and mastoid antrum, 59 (92%) had erosions of the ossicles, with involvement of the long process of the incus in 48 (75%), 55 (86%) had an eroded scutum, 55 (86%) an eroded facial nerve canal, 57 (89%) an eroded Koerner’s septum, which was totally destroyed in 19 (27%), 48 (75%) had tegmen erosion, and 63 (98%) had erosions of the antral walls. The correlation of pre-operative CT with surgical and histopathological findings was 97%.CONCLUSIONMiddle ear cholesteatoma is a distinct clinical entity with characteristic findings that may be suggested by CT imaging. These findings should alert the clinician to the possibility of cholesteatoma, which will guide in the surgical approach and treatment plan.

“…5). Computed tomography is also helpful in imaging repaired fistulas of the lateral semicircular canal, and in showing the bony density of the reconstructed part of the canal [7,8,9,10]. Magnetic resonance can sometimes be helpful in differentiating inflammatory changes, cholesteatoma, and tumor in those cases in which accurate diagnosis cannot be achieved with CT alone [11].…”

CT and MRI of the semicircular canals in the normal and diseased temporal bone

et al. 2000

View full text Add to dashboard Cite

Imaging of the semicircular canals specifically is part of the imaging process of the temporal bone in general. The semicircular canals are easily seen on CT images and 3DFT-CISS-weighted MR images, both performed with 1.0-mm-thick slices, or even thinner slices. In selected cases, the T1-weighted images give unique information on the semicircular canals. This article briefly reviews the variety of semicircular canal anomalies that are most frequently present and can be routinely seen on CT and MR examinations of the temporal bone. It also provides a list that can be used by the radiologist in clinical practice to decide which technique, CT or MR, should be used to detect specific anomalies at the level of the semicircular canals.
