Eleven patients with dural fistulas involving the transverse and sigmoid sinuses were treated by transvenous embolization with coils or liquid adhesives. Seven patients underwent preoperative embolization of the external supply followed by direct surgical exposure of the sinus: liquid adhesives were used in four patients and coils in the remaining three. Four of these patients had complete obli...
BACKGROUND AND PURPOSE The size of vestibular aqueducts (VAs) seen on CT studies varies. The current practice of calling a VA enlarged when it exceeds a certain threshold (eg, 1.5 mm at the midpoint) is arbitrary. Our hypothesis was that statistical analysis of the range of VA widths in a normal-hearing population would lead to a mathematic definition of the upper-limit-of-normal VA width. MA...
If a drastic change in hearing has occurred in a child following a minor head trauma, change in barometric pressure, or physical exertion, large vestibular aqueduct syndrome (LVAS) should be considered. Most audiologists are unaware of LVAS or do not suspect it, in part due to the presence of a conductive component. LVAS can be seen in conjunction with Mondini's dysplasia or may appear by itsel...
OBJECTIVE To determine the incidence of high jugular bulb in a group of patients with definite Ménière's disease, and to investigate whether the position or size of the jugular bulb is significantly different in the affected ear than in the unaffected ear. METHODS Retrospective review of patient charts, audiograms, and computed tomography scans to determine the position and size of the jugula...
Although enlarged vestibular aqueduct syndrome (EVAS) has been reported to be one of the most common anomalies associated with sensorineural hearing loss, the mechanism of such loss is unclear, and there are no established criteria for diagnosis. We report 4 patients with sensorineural hearing loss that were diagnosed during the last year in our department of EVAS. We review the diagnostic crit...
