OBJECTIVE The purpose of this study was to elucidate the rotation axes of the slow and quick phase of the caloric nystagmus using the video-oculographic technique. METHODS Subjects were placed in a supine position and cold-water stimulation was applied to the right ear canal. The eye movements were recorded in complete darkness by a high-speed infrared(More)
In order to record and analyze the rapid eye movement non-invasively in human subjects, a four times high-speed video camera (4TC) with a new computer software was developed and utilized. Nine healthy volunteers and four patients with vestibular dysfunction participated in this study. Caloric stimulation was applied to the healthy subjects and the eye(More)
CONCLUSIONS The cochlin-tomoprotein (CTP) detection test can be used to make a definite, objective diagnosis of traumatic perilymphatic fistula (PLF), and therefore offers valuable information on patient selection for surgical treatment. OBJECTIVES Penetrating middle ear injury can cause traumatic PLF, which is a surgically treatable otologic emergency.(More)
CONCLUSIONS By testing 125 samples, we confirmed that Cochlin-tomoprotein (CTP) is present in the perilymph, not in cerebrospinal fluid (CSF). Perilymph and CSF exist in two distinct compartments, even in the case of a malformed inner ear with a bony defect in the lamina cribrosa, as described here. Cochleostomy might have suddenly decreased the perilymph(More)
OBJECTIVE The pathological localization of vestibular neuritis is still controversial. Analyses of the spontaneous nystagmus support the temporal bone studies, which indicated the location of the pathology to be in the superior vestibular nerve. However, based on the data from the head impulse testing the pathology is in the vestibular nerve including the(More)
