“…CT imaging has also been instrumental in analyzing anatomical variations in the nose and paranasal sinuses, highlighting its significance in capturing fine bone architecture and soft tissue structures (Makhdoomi et al, 2021). Furthermore, the use of CT scans for temporal bone analysis has been emphasized in the literature, indicating its crucial role in providing detailed and accurate imaging for diagnostic and surgical purposes (Polanski et al, 2018).…”

Background This study explored the morphological anatomy of otic prominences in camels using advanced computed tomography (CT). Nine adult cadaver camel heads underwent CT scanning to generate detailed images of the otic prominences, mastoid process, styloid process, stylomastoid foramen, external acoustic meatus, bulla tympanica, and muscular processes. The morphological anatomy of otic prominences was studied in nine skulls. Results The anatomical features were analyzed, revealing a compact and closely collected configuration of otic prominences. Unique characteristics of the mastoid process, bulla tympanica, and styloid process were observed, challenging the conventional descriptions. Conclusions This study underscores the value of CT scans in enhancing anatomical studies and provides insights into comparative veterinary anatomy, facilitating the evaluation of various conditions and disorders in camels.

“…Therefore, the use of deep learning algorithms may help in detecting subtle otosclerotic foci in routine HRCT scans [ 25 ]. Another solution would be to include the antefenestral region in all structured HRCT reports and check lists [ 26 , 27 ], which will drive readers to address the presence versus absence of otosclerosis in all scans.…”

Objectives: Several studies reported low detection rates of otosclerosis in high-resolution computed tomography (HRCT), especially when the scans were reviewed by non-specialized general radiologists. In the present study, we conducted a retrospective review of the detection of otosclerosis in HRCT by general radiologists and the impact of inadequately filled radiological request forms on the detection rate. Methods: Retrospective analysis of hospital records, HRCT reports, and radiological referral notes of 40 patients who underwent stapedotomy surgery for otosclerosis. HRCT imaging data sets were retrospectively reviewed by a blinded experienced neuroradiologist, whose reading served as the gold standard. Results: General radiologists reading HRCT scans had an overall detection rate of otosclerosis of 36.1% in this cohort (13 of 36 available HRCT reports). The neuroradiologist had a much higher detection rate of 82.5% (33 of 40 cases). Interobserver agreement between the general radiologists and the subspecialist neuroradiologist was poor (Cohen’s kappa κ = 0.26). General radiologists missed the diagnosis in 15 of the 33 CT-positive scans, corresponding to a missed diagnosis rate of 45.4%. There was a highly significant association between a missed diagnosis and the lack of an explicitly mentioned clinical suspicion of otosclerosis in the request forms (Pearson’s chi-squared test, p < 0.005). Conclusion: The diagnosis of otosclerosis is frequently missed by radiologists on HRCT scans of the temporal bone in a clinical setting. Possible reasons include a relative lack of experience of general radiologists with temporal bone imaging as well as the failure of clinicians to unambiguously communicate their suspicion of otosclerosis.

“…The multiplanar reconstruction (Axial, coronal and sagittal view) helps surgeon to identify the anatomical and pathological overview of the temporal bone, thus it assists surgeon to plan the surgery. [1][2][3] Since there is difficulty in identifying the different structures of temporal bone while reading the HRCT of temporal bone, so we developed our own Dhulikhel Hospital Checklist protocol for evaluation of Temporal bone CT scan prior surgery. (Table 1) We hope this protocol will help every otologist to read CT scan without any difficulty.…”

The temporal bone is very complicated anatomical structure. Any disease process within this structure mandates thorough anatomical knowledge of the corresponding structure. The High resolution computed tomography (HRCT) temporal bone is the best way to look inside this complex bone. The importance of knowledge about how to read and look inside the CT scan temporal bone lead us develop the Dhulikhel Hospital Check list protocol. This protocol will help aspiring otologist and otolaryngologist to read and know details about the underlying structures.
