With the availability of high-resolution computed tomography (CT), a great deal of attention has been paid to the anatomy of the paranasal sinuses. But while investigators have focused on the osteomeatal complex and its relation to chronic rhinosinusitis, there has been little discussion of the superior turbinate. Although a few anatomic studies have tried to quantify pneumatization of the superior turbinate, the prevalence of this finding on radiography is not well addressed in the literature. We prospectively studied 100 consecutively presenting patients who underwent coronal CT of the paranasal sinuses (200 sides) for the evaluation of symptoms of chronic rhinosinusitis at an academic tertiary referral center to determine the prevalence of pneumatization of the superior turbinate. We found evidence of pneumatization in 44 of the 200 sides, for a prevalence of 22%. In all, pneumatized superior turbinates were found in 27 patients (27%)—bilaterally in 17 (17%) and unilaterally in 10 (10%).

Objectives: This is a qualitative study to explore the utility of gray-scale inversion or the “invert” function of high-resolution computed tomography (HRCT) scans in the diagnosis of temporal bone anatomy and pathology. Methods: This is a case series describing an innovative application of an existing image processing tool to visualize temporal bone anatomy and pathology. Illustrative patients at a tertiary referral center with otologic symptoms and findings leading to HRCT scans of the temporal bone were included. Diagnostic HRCT scans were evaluated utilizing the gray-scale inversion function (invert function). Results: Nine illustrative cases which demonstrate conditions such as persistent stapedial artery, membranous stapes footplate, total ossicular prosthesis migration into the vestibule, third window syndrome such as superior semicircular canal dehiscence (SSCD) and cochlea-facial nerve dehiscence, otosclerosis, and ossicular chain discontinuity are included. The enhanced visualization was confirmed surgically in 3 cases, and 1 had physiological confirmation using cervical vestibular evoked myogenic potentials (cVEMP). Conclusions: Gray-scale inversion can be used to improve visualization of temporal bone anatomy and pathologic changes when diagnoses are in doubt. The invert function is a useful adjunct in the armamentarium of both radiologists and otologists when evaluating HRCT of the temporal bone.

<p class="abstract"><strong>Background:</strong> <span lang="EN-IN">Cholesteatoma is relatively common and potentially dangerous disease of the ear. It is characterised by local destruction and osseous erosion leading to complications. High resolution computed tomography (HRCT) is the imaging modality of choice for evaluation of middle ear structures and pathology. The aim of this study is to evaluate role of preoperative HRCT in the diagnosis of the disease, its extension and complications and plan for surgery.</span></p><p class="abstract"><strong>Methods:</strong> <span lang="EN-IN">This prospective study was conducted at a tertiary referral teaching hospital and 40 cases of cholesteatoma were selected and their pre-operative HRCT temporal bone findings and intraoperative findings were correlated.  </span></p><p class="abstract"><strong>Results:</strong> <span lang="EN-IN">This study showed good correlation between preoperative HRCT findings of cholesteatoma, and intraoperative findings. </span></p><p class="abstract"><strong>Conclusions:</strong> <span lang="EN-IN">We conclude therefore the preoperative HRCT temporal bone is useful guide for the surgeon for the diagnosis and management of cholesteatoma.</span></p>

Respiratory system diseases are one of the main problems in contemporary occupational medicine and exceed one fifth of all occupational diseases. Objective of the review was search and analysis of literature on diagnosis of silicosis as an important occupational disease of respiratory organs, by computed tomography and high-resolution computed tomography, from evidence-based medicine viewpoint.
