“…13 In the current CT scan study, three of the six tumors observed were glomus tympanicum tumors, more commonly in female patients than male (2:1), in line with literature. 10 The other tumors observed in this study were middle ear malignancy and EAC malignancy.…”

“…While magnetic resonance imaging may be better than CT for delineating tumour edges and intracranial extent; CT scans are best for evaluating bony destruction and erosion, which is a hallmark of jugulotympanic glomus tumours. 10 Other vascular abnormalities like high jugular bulb or an aberrant carotid artery can masquerade with a similar presentation as glomus but CT scan features are helpful in ruling out these abnormalities. 11 Primary malignant tumors of EAC are rare with squamous cell carcinoma (SCC) being by far the most common EAC malignancy.…”

INTRODUCTIONDue to the complex anatomy of the temporal bone, conventional radiological methods like X-ray mastoid have limited ability to delineate the details of the temporal bone and cochlea-vestibular anatomy and disease pathology. The availability of modern highresolution computerized tomography (HRCT) scanners has resulted in ability to demonstrate the detailed temporal bone anatomy and identify significant structures and has revolutionalized the role of radiology in diagnosis and management of temporal bone diseases. 1 HRCT is particularly helpful in evaluating the anatomy and pathology of external auditory canal, middle ear cavity, vestibular aqueduct, tegmen tympani, sigmoid sinus plate, vertical segment of facial nerve canal, sinodural angle, carotid canal, jugular fossa, infra and supralabrynthine air cells and temporomandibular joint; both soft tissue extension and significantly sensitive ABSTRACT Background: Conventional radiological methods like X-ray mastoid have limited ability to delineate the details of the complex temporal bone and cochlea-vestibular anatomy and disease pathology. This can be overcome by the use of High resolution computed tomography (HRCT) evaluation of the temporal bone. HRCT is helpful in evaluating the anatomy and pathology type and extent of disease, thereby helps in preoperative planning. Methods: The CT scan of forty five patients attending the outpatient department of otorhinolaryngology in a tertiary care centre between August 2014 to August 2017 was evaluated in this study. Each CT scan was interpreted by an otolaryngologist and a radiologist and interpretation was by consensus. The data collected was evaluated and results are reported as rates and proportions (%). Results:The study evaluated CT scan of 45 patients of which 35 were male patients and 10 were female patients with age ranging from 5 years to 75 years. Most of these patients belonged to the 21-30, 31-40 age groups [9 (20%) in each group]. Infections of middle ear cleft (all with cholesteatoma), fractures of the temporal bone, anomalies and tumors of the external auditory canal and middle ear were the pathologies observed in these CT scans with infection (otomastoiditis) [23 (51.1%)] being the most common pathology observed. Conclusions: Pre-operative CT scan may not only help in identifying the nature, extent of infectious disease including ossicular, bony erosions; it may also identify anomalies in the temporal bone and surrounding structures. Thus, HRCT temporal bone will help the surgeon in planning effective surgical strategy, reducing morbidity during the surgery.

“…Jugulotympanic paragangliomas-comprising glomus jugulare and glomus tympanicum tumors-may also involve the round window. 48,49 Glomus tympanicum tumors arise from the tympanic nerve (Jacobson nerve) and grow within and along the cochlear promontory; if large enough, they may extend into and occlude the round window niche. 48 Glomus jugulare tumors begin within the jugulare foramen.…”

The round window serves to decompress acoustic energy that enters the cochlea via stapes movement against the oval window. Any inward motion of the oval window via stapes vibration leads to outward motion of the round window. Occlusion of the round window is a cause of conductive hearing loss because it increases the resistance to sound energy and consequently dampens energy propagation. Because the round window niche is not adequately evaluated by otoscopy and may be incompletely exposed during an operation, otologic surgeons may not always correctly identify associated pathology. Thus, radiologists play an essential role in the identification and classification of diseases affecting the round window. The purpose of this review is to highlight the developmental, acquired, neoplastic, and iatrogenic range of pathologies that can be encountered in round window dysfunction.

“…It also allows assessment of the bony structures of the middle ear, the inner ear and the jugular foramen. MRI, on the other hand, perfectly describes relation of the tumor to the surrounding soft structures, vessels and invasion both intra-and extracranial [5,6,7]. The main goal of paraganglioma treatment is complete tumor resection.…”

Objective: The aim was to determine the clinical characteristics and analysis of surgical treatment of patients with glomus tympanicum hospitalized in the Department of Otolaryngology of Warsaw Medical University. Material and methods: Between 2000 and 2015, 27 patients were hospitalized. Age ranged 28–79 years old. The study analyzed data from the clinical examination and the type of surgical technique. Results: The most common symptoms were tinnitus and hearing loss. Resection of the tumor was performed by anterior tympanotomy in 3 (11,1 %), CWU mastoidectomy in 21 (77,8%), CWD mastoidectomy in 1 (3,7%), lateral petrosectomy in 2 patients (7,4%). Conclusion: Glomus tympanicum were more common in women than in men. The most common symptoms were unilateral tinnitus and hearing loss. The most of the paraganglioma were operated in the second stage. Glomus tympanicum were usually resected via CWU mastoidectomy.
