This prospective case review was performed with the aim to compare and asses the diagnostic values of cone-beam computed tomography (CBCT) and high-resolution computed tomography (HRCT) in the preoperative evaluation of otosclerosis. A total of 43 patients with histologically confirmed stapedial otosclerosis, who underwent unilateral stapedectomies were(More)
Generation of reactive oxygen species (ROS) in synaptosomes was investigated in the presence of different substrates. When pyruvate was used as a substrate an increased rate of hydrogen peroxide formation was detected by the Amplex Red fluorescent assay, but aconitase, which is known to be a highly sensitive enzyme to ROS was not inhibited. In contrast,(More)
HYPOTHESIS Different diseases without exact histopathologic classification can cause stapes ankylosis. BACKGROUND Otosclerosis is a complex bone remodeling disorder of the otic capsule due to persisting measles virus infection and consecutive inflammatory reaction. In fact, clinical and demographic features of otosclerosis have reference to stapes(More)
HYPOTHESIS Otosclerosis is an inflammatory bone remodeling disorder of the human otic capsule, which might be characterized by a disturbed balance between cell survival and apoptosis due to an increased expression of inflammatory cytokines, mainly tumor necrosis factor-[alpha] (TNF-[alpha]). BACKGROUND Histologic features of otosclerosis have been well(More)
The present study is intended to explore the effects of the KTP laser on various types of implant, used in middle-ear surgery. A laboratory study was undertaken to evaluate the interaction between the KTP laser (KTP-532 Orion Laser, Laserscope, UK) and individual middle-ear implants. A variety of middle-ear implants were used: a silicone sheet, Teflon,(More)
CONCLUSION This study is the first to establish that bone morphogenetic protein 5 (BMP5) plays a role in the pathogenesis of otosclerosis. These results confirm that elevated expression levels of BMPs, members of the transforming growth factor (TGF)-β superfamily, contribute to the pathologically increased bone turnover in early, active stages of(More)
Infections in the neck layers and spaces are potentially life-threatening diseases causing further complications, like mediastinitis, airway obstruction, or sepsis. Despite of the need for a conservative approach, they still regularly require surgical intervention. Records of 17 patients with severe neck infections that were treated by wide external(More)
Tuberculosis remains one of the most challenging infectious diseases, which rarely manifests in the middle ear cleft exclusively. Typical symptoms of tuberculosis have become more and more confusing due to the genetic evolution of different Mycobacterium species. In the diagnosis of tuberculous otitis media (TOM), clinical suspicion plays a fundamental(More)
