“…[3] The extent and course of the fracture line, in relation to the long axis of the temporal bone, and the related complications are important in estimating the prognosis [Figures 6 and 7A, B]. [14] Occasionally the history of injury may not be available and the fracture may be very subtle; getting the correct clinical information and careful analysis of HRCT will avoid the pitfall.…”

Middle ear disease is a common clinical entity; imaging, especially High resolution Computed Tomography (HRCT), plays a crucial role in diagnosis and assessing the disease extent, helping to decide appropriate management. Temporal bone imaging is challenging and involves thorough understanding of the anatomy, especially in relation to HRCT imaging. Most of the middle ear pathologies appear as “soft tissue” on imaging. Careful analysis of the soft tissue on the HRCT is crucial in achieving the right diagnosis; clinical information is essential and the imaging findings need correlation with clinical presentation and otoscopic findings. The purpose of this pictorial essay is to enlist the pathologies that present as soft tissue in middle ear and to provide a structured and practical imaging approach that will serve as a guide for confident reporting in daily practice.

Chronic Suppurative Otitis Media (CSOM) is a chronic inflammation of middle ear cleft. It presents with discharging ear and decreased hearing. The diagnosis is mostly on clinical examination with otoscope or oto endoscope. Computerised Tomography (CT) of mastoids is done to evaluate the extent of the disease and its complication. High resolution CT is now the investigation of choice for temporal bone disease. This study emphasizes on the importance of CT scan in diagnosis of inflammatory ear diseases and most importantly identifying pitfalls or complications which a surgeon can come across during surgery. The aims and objectives of this study is (1) to establish the efficacy of CT in the diagnosis of the complications and surgical management of chronic inflammatory pathologies of middle ear. (2) To find subgroups of CSOM where CT is particularly useful. In this series, a total of 25 cases presenting to our OPD at Govt. ENT Hospital between 2013 and 2014 have been diagnosed and findings of surgery correlated with HRCT scan of temporal bones done preoperatively. In this study, 64 % of the patients were male and incidence of CSOM with patients undergoing surgery belonged to the age group 21-30 years (32 %). The most common presenting symptom was ear discharge (92 %) and decreased hearing (96 %). The most common type of pathology in this study was attic perforation (36 %) and granulations (40 %) followed by cholesteatoma (36 %) and mucosal edema (16 %). Not all cases presented with complications, facial palsy (12 %) and mastoid abscess (8 %) were among few complications seen. 14 patients (56 %) of 25 cases underwent simple cortical mastoidectomy followed by 9 cases (36 %) for modified radical mastoidectomy and atticotomy for 2 cases (8 %). CT scan findings correlated well with surgical findings for cholesteatoma, middle ear mass and bone erosions. Where as for ossicular integrity and facial canal dehiscence, there was a discrepancy.

“…Radiologic findings of external and middle ear diseases in CGD patients are similar to those of patients with normal immunity. In particular, necrotizing otitis externa, an infection that occurs in the cartilage and bones of the external auditory canal, develops mainly in immunocompromised patients (12). On the CT scan, the skin of the external auditory canal and the auricle are thick with contrast enhancement.…”
