BACKGROUND To identify predictors for development of mastoiditis after intensity-modulated radiation therapy (IMRT) in nasopharyngeal carcinoma (NPC). METHODS Data for 146 NPC patients treated with IMRT was retrospectively reviewed under institutional ethics committee approval. Clinical factors associated with mastoiditis were analyzed. Dose-volume histogram analysis was performed for the Eus...

AIM Surgical anatomy concerning the posterior craniovertebral region in fresh human cadavers was studied to provide most accurate information for the surgical approach. MATERIAL AND METHODS In thirty-two fresh human cadavers, the distance from the posterior tubercle to the sulcus of vertebral artery (VA), the thickness and length of the third segment of VA (V3), the distance of C1/C2 facet to...

UNLABELLED Computed tomography-based measurements of mastoid surface area and volume have not been described for adult Brazilian individuals. These measurements add to the understanding of middle ear physiology, related diseases, and their impact on mastoid pneumatization. OBJECTIVE To check the ratio between mastoid surface area and volume. METHOD This contemporary cross-sectional cohort s...

SummaryMalignant tumours of the mastoid are rare, the majority being squamous cell carcinomas. We report two cases whose clinical presentation mimicked mastoid abscess with intracranial complications. The first case is a twenty year Nigerian lady who presented to the Emergency Room of the Otorhinolaryngology Department with a one month history of headache, low grade fever, left facial palsy, ne...

OBJECTIVE Congenital mastoid cholesteatomas are rare lesions of the temporal bone. The clinical presentation of these lesions is variable, making them difficult to identify preoperatively. We evaluated our series of mastoid congenital cholesteatomas (CCs) in an effort to better define the clinical presentation, imaging characteristics, and surgical challenges specific to this lesion. STUDY DE...

The incidental finding of an enlarged mastoid foramen on the right posterior mastoid region of temporal bone is reported, together with a discussion of its clinical significance. A 67-year-old female underwent the pre-implant assessment of a maxillary left edentulous region. A cone-beam computed tomographic (CBCT) image was acquired and referred for consultation. Axial CBCT slices revealed a un...

A 36-year-old male who had history of hearing loss since childhood presented with a chronically discharging right ear. HRCT temporal bones revealed non-dependent opacification in the epiand meso-tympanum with medially displaced head of malleus, erosion of incus and the tegmen tympani suspicious for an attic cholesteatoma. In addition, there was a serpiginous structure seen extending across the ...

Abstract Evaluating the effectiveness of different bone conduction (BC) transducers with controlled coupling force to elicit cervical and ocular vestibular evoked myogenic potentials (cVEMPs, oVEMPs) in healthy subjects by comparing response rates, amplitudes, latencies, thresholds asymmetry ratios. Prospective experimental study including participants. VEMPs were measured stimulation modes; BC...

Cochlear implant (CI) surgery in the setting of an open mastoid cavity is evolving. Two strategies are commonly pursued: a staged approach, clearing the disease, closing the meatus or the external auditory canal (EAC), and reevaluating in 3 to 6 months prior to implantation, or a single-stage procedure with mastoid obliteration without EAC closure. Meatal closure is often employed in the settin...

Two-stage methods for reconstruction of congenital microtia have been widely utilised. To obtain a desirable auriculocephalic angle and provide a nutrient support to the constructed auricle, elevation of reconstructed ears using a costal cartilage graft, the anteriorly based mastoid fascial flap transfer and a skin graft was performed as the second operation for nine microtia patients. In this ...
