OBJECTIVE Because of the intricate anatomy of the temporal bone, we examined the feasibility and reliability of cranial surface anatomic fiducials to register computed tomographic images of the temporal bone by using a frameless image-guided system. METHODS One-millimeter thick computed tomographic slices and the smallest possible field of view were used(More)

It is known that Meniere's disease is attributable to endolymphatic hydrops, caused(More)
OBJECTIVE To report the authors' experience with transtympanic electrocochleography during the past 10 years. STUDY DESIGN Retrospective case review. SETTING Otology/neurotology referral center. PATIENTS Transtympanic electrocochleography was performed on 2,421 ears of 2,140 patients from May 1990 to April 2000. INTERVENTION Clicks and tonebursts(More)
OBJECTIVE This study aimed to compare the summating potential and action potential ratio (SP:AP) in patients with Meniere's disease before and after various surgical and medical treatments as an indication of change in endolymphatic hydrops to study the progression of Meniere's disease. STUDY DESIGN The study design was a retrospective case review. (More)
Despite a body of literature focusing on the functionality of modern and stylistically distinct projectile points, comparatively little attention has been paid to quantifying the functionality of the early stages of projectile use. Previous work identified a simple ballistics measure, the Tip Cross-Sectional Area, as a way of determining if a given class of(More)
