OBJECTIVES/HYPOTHESIS To define the surgical treatment and outcomes of von Hippel-Lindau (VHL) disease-associated endolymphatic sac tumors (ELSTs), we analyzed consecutive VHL patients who underwent ELST resection. STUDY DESIGN Retrospective investigation of consecutive VHL patients who underwent resection of ELSTs at a clinical research center between 1999 and 2010. METHODS Analysis of ser...
There are large individual differences in susceptibility to noise exposure. Most hearing impairment begins with dip type hearing loss, and continual evoked otoacoustic emissions (C-EOAEs) are frequently seen in ears with dip type hearing loss. The present study was performed in order to ascertain the relationship between dip type hearing loss and C-EOAE. Brass band members in two junior high sc...
Multiple Sclerosis (MS) is a demyelinating disorder of Central Nervous System. It involves 8th cranial nerve and its central nuclei and is an uncommon cause of the sensorineural hearing loss. For determining the prevalence of hearing loss (HL) especially retrocochlear type in MS, a cross-sectional study was designed using Pure-Tone Audiometry (PTA), Otoacustic Emissions (OAEs), Auditory Brainst...
Photoacoustic microscopy has achieved submicron lateral resolution, but its axial resolution is much lower. Here an axial resolution of 7.6 μm, the highest axial resolution validated by experimental data, has been achieved by using a commercial 125 MHz ultrasonic transducer for signal detection followed by the Wiener deconvolution for signal processing. Limited by the working distance, the high...
