SUMMARY We report the CT and MR findings in a patient with malignant peripheral nerve sheath tumor in the parapharyngeal space who had neither a family history nor stigmata of neurofibromatosis. A high-resolution CT scan of the temporal bone revealed bony erosion and widening of both the foramen ovale and the bony portion of the eustachian tube. A temporal bone MR image showed an intensely enha...

Intracardiac echocardiography (ICE) is increasingly being used to guide electrophysiologic (EP) procedures, improve procedure safety and reduce fluoroscopy. However, many practitioners have limited ICE experience. Anatomy labeling expected increase physician confidence streamline their workflow. We developed a fully automated deep learning-based approach predict label anatomic locations structu...

Abstract Background Results of previous trials about PFO closure as a treatment for migraine are still doubtful and inconclusive. We sought to evaluate the long–term (>10 years) effectiveness by means patent foramen ovale (PFO) closure. Methods From 2006 2010, 86 patients (68 female, mean age 40.0 ±3.7 with disabling, medication–refractory were enrolled in prospective study over 48–month...

Types E very acoustical system has an underlying level of noise. High-fidelity buffs refer to the signalto-noise ratio. The human auditory (acoustic) system is no exception. Other normal physiological noises include the sound of the pulse in the inner ear, the opening of the eustachian tube, the noise of respiration , and the like. Pathological tinnitus, on the other hand, is noise associated w...

Although it has been reported that smoking has deleterious effects on the middle ears of smokers, including their eustachian tubes, investigators have failed to find differences in the tympanometric characteristics of smokers and nonsmokers. In the present study, however, we found that the Valsalva-induced tympanometric peak pressure shifts of young smokers were less than those measured among y...
