“…HRCT accurately predicted 94% of cases of incus erosion. Incus is the most eroded ossicle in our study similar to reports by Amit Shankhwar et al 13 and Rohit Vallabhaneni et al 14 Sonika Kanotra et al 15 Datta et al 16 and Rai et al 17 observed slightly low sensitivity of 87% and 85%. HRCT accurately predicted in 43% of cases of malleus erosion which was found to be eroded intraoperatively as well.…”

This was a prospective study, done in our institution from January 2016 to August 2017 with a sample size of 90, after due clearance from the institutional ethical committee. Written informed consent was obtained from all patients prior to the study procedure or data collection. Patients of all age group with ear complaints, such as hearing loss, pain, vertigo, ear discharge and tinnitus referred for HRCT temporal bone were included. Patients with a recent history A B S T R A C T Introduction: Diseases of the ear are a common clinical problem, encountered in every day. Clinical examination alone is not sufficient in present days, owing to prevalence, complications and recurrence of various pathologies of the temporal bone, imaging plays a major role in the management and influences the treatment. High-resolution computed tomography (HRCT) offers an excellent resolution, allowing a better understanding of the aetiology, pathology, disease course with early detection of complications. The prospective study aimed to study pathologies of the temporal bone along with their complications on HRCT and to correlate with their surgical findings. Material and Methods: A prospective study done with a sample size of 90 patients with ear complaints, such as hearing loss, pain, vertigo, ear discharge and tinnitus and referred for HRCT temporal bone were included. Ear trauma and head injury, pregnant women and those unwilling to give consent were excluded. HRCT was done using a GE 128 Slice CT scanner and were followed up for surgical or medical methods of management. Images are reconstructed in the ultra-sharp bone algorithm for image reconstruction, analysed for reporting. The intraoperative findings such as middle ear soft tissue density, ossicular erosion, erosion of scutum, tegmen tympani and facial canal, fistulous communication between the middle ear and lateral and posterior semicircular canal. Above findings were analyzed using standard statistical methods. Results: There is an excellent radio-surgical correlation in diagnosing and differentiating cholesteatoma from granulation tissue, identifying malleus erosion, incus erosion, tegmen tympani erosion, scutum erosion, EAC erosion, sigmoid plate dehiscence, high riding jugular bulb, mastoid status/erosion. Moderate to poor radio-surgical correlation was noted in identifying LSCC fistula, stapes erosion and facial canal erosion. Conclusion: HRCT is a valuable imaging modality through which pre-operative assessment of temporal bone pathologies can be done efficiently with reasonable accuracy, cost and precision for making surgical decisions. Hence it helps the surgeon to decide the course of action in particular clinical problem.

“…The use of single plane may lead to mistakes because the structures parallel to the plane of section are not visualized. 10 With the more prevalent use of HRCT scanning, considerable morbidity may be avoided. Because of the ability to see middle ear structures with great clarity, more limited and more directed procedures can be done to eradicate disease while preserving function.…”

INTRODUCTIONCholesteatoma is a long-standing infection of the middle ear cleft. It is a three-dimensional stratified squamous epithelial sac confirming to the middle ear cleft, containing keratin debris and having the capacity for progressive and independent growth at the expense of the underlying bone, displacing or replacing the middle ear mucosa, and has a tendency to recur after removal.1 It has a destructive nature that erodes the bone and causes rapid bone destruction. Cholesteatoma have characteristics of growth, migration and osseous erosion and are thus locally destructive, the only treatment is their full surgical removal since there is no effective clinical treatment for eradication of the disease so far. 2Chronic ear discharge and decreased hearing are most common clinical presentation in cholesteatoma disease. Other symptoms are tinnitus, earache, ear bleeding. Other warning symptoms are headache, high grade fever, vomiting, giddiness and facial asymmetry suggestive of intratemporal and intracranial complications. ABSTRACTBackground: Cholesteatoma is a long-standing infection of the middle ear cleft having erosive properties. Chronic ear discharge and decreased hearing are most common clinical presentation. Multi-directional tomography of high quality can provide a detailed understanding of the interpretation of anatomical structures visualized by HRCT. Knowledge of the anatomical variations and changes induced by pathology in the temporal bone are the guiding marbles for surgery. Methods: This is a prospective study consisted of 100 cases of chronic suppurative otitis media of unsafe type requiring ear surgery admitted in the E.N.T. department of P.D.U. Civil Hospital Rajkot in 2 years from December 2015 to December 2017. A total no. of 100 patients of both gender between 5 to 80 years has been included in the study. Results: In this study, 58% patients were females while males were 42%. Left ear (46%) was involved more as compared to right ear (40%). Most of the patients belonged to 11-20 (25%) years of age group. Mean age is 24.5 years. Most common symptoms were ear discharge (98%) and decreased hearing (83%). Conclusions: HRCT guides the surgeon on the possible surgical hazards before the surgery and helps in earlier management and operative complications. The use of CT in the case of chronic suppurative otitis media does provide valuable information. HRCT scanning is a unique method of detection of early cholesteatoma as well as detection of cholesteatoma in hidden areas. In addition, HRCT scanning serves as a road map to assist the surgeon during cholesteatoma surgery.

“…These findings were similar to Tripti. 12 On normal side, x-ray of the mastoids revealed pneumatised mastoid in 61.1%, diploeic in 2.8% and sclerosed mastoid in 36.1% of the cases. HRCT temporal bone revealed pneumatised mastoid in 61.1%, diploeic in 5.6%, and sclerosed mastoid in 33.3% of the cases.…”
