In recent years, carbon nanotubes have been utilized for a variety of applications, including nanoelectronics and various types of sensors. In particular, researchers have sought to take advantage of the superior electrical properties of carbon nanotubes for fabricating novel strain sensors. This article presents a single-walled carbon nanotube(More)
PURPOSE It is assumed that preoperative use of a bone-anchored hearing aid (BAHA) test-band will give a patient lower gain compared to real post-operative gain because of the reduction of energy through the scalp when using a test-band. Hearing gains using a BAHA test-band were analyzed in patients with unilateral hearing loss. MATERIALS AND METHODS(More)
CONCLUSION Our findings suggest that migrainous vertigo (MV) has a substantial vestibulo-spinal abnormality that can be uncovered by posturography. Patients with MV also showed a difficulty in using multisystem information, especially somatosensory information. Caloric and sensory organization tests (SOTs) have complementary roles in assessing(More)
OBJECTIVE We aimed to determine whether abnormalities in outer hair cell (OHC) function were related to tinnitus through interaural comparison of distortion product otoacoustic emissions (DPOAEs). STUDY DESIGN Cross-sectional study. SETTING Tertiary care university teaching hospital. PARTICIPANTS Twenty-seven patients with unilateral tinnitus and(More)
We evaluated the short-term efficacy of Epley, Semont, and sham maneuvers for resolving posterior canal benign paroxysmal positional vertigo (BPPV) in a prospective multicenter randomized double-blind controlled study. Subjects were randomly divided into three groups: Epley (36 patients), Semont (32 patients), and sham (Epley maneuver for the unaffected(More)
OBJECTIVE To compare audiologic performances of cochlear implantation (CI) in children with X-linked deafness with those of CI in age- and sex-matched children with normal cochleae. PATIENTS We identified 4 patients with X-linked deafness and selected 10 age- and sex-matched deaf patients with normal cochleae between April 1999 and April 2012. MAIN(More)
The HSN test is a simple examination that can be easily performed by clinicians, however only a few studies have analyzed the 2-dimensional characteristics of HSN in patients with MD. The objective of the study was to characterize different types of 2-dimensional head-shaking nystagmus (HSN) in patients with Meniere's disease (MD). Sixty-five patients with(More)
BACKGROUND AND OBJECTIVES Gingko biloba extract is known for enhancing blood circulation, scavenging free radicals, and antagonizing against platelet-activating factor. This study evaluated the effect of Gingko biloba on the noise-induced temporary threshold shift of hearing. MATERIALS AND METHODS Temporary threshold shift was induced by exposing mice to(More)
BACKGROUND AND OBJECTIVES The purpose of the study was to compare the mastoid air-cell volume of the patients with superior semicircular canal dehiscence syndrome (SCDS) and that of the control patients with otosclerosis and temporal bone (TB) fracture. SUBJECTS AND METHODS Ten patients with SCDS were enrolled and 10 patients with bilateral otosclerosis(More)
