EVALUATION OF ANATOMICAL VARIATIONS OF VESTIBULAR AQUEDUCT DIMENSIONS IN TEMPOR AL BONE CT SCAN
Authors
Abstract:
Various dimensions of the human vestibular aqueduct were evaluated in two groups, patient and control, and these measurements were compared. Both groups were examined clinically, followed by audiometric evaluation and temporal bone high resolution CT scan. It was found that in approximately one third of the patient group (with idiopathic SNHL), the vestibular aqueduct was 1.5 mm or larger. Also, the midpoint diameter of the distal limb was larger than in the control group (p<0.01). But there was no relation between the various dimensions of the vestibular aqueduct and mastoid pneumatization.

OBJECTIVES/HYPOTHESIS Patients with enlarged vestibular aqueduct (EVA) often demonstrate an air-bone gap (ABG) at low frequencies on audiometric testing. The mechanism for this has not been well elucidated. We investigated vestibular aqueduct (VA) size and ABG in patients with EVA, and assessed the relationship between VA diameter and ABG. STUDY DESIGN Retrospective review. METHODS We asses...

چکیده: یکی از دوره های مهم تاریخی ایران به لحاظ تأمین استقلال ملی مذهبی و حتی تأثیر آن بر فرهنگ و مذهب ایرانیان، دوره صفویه است. رسمیت دادن و رواج مذهب شیعه توسط شاه اسماعیل اول، یکی از مهمترین اقدامات این دولت محسوب می شود. بنابراین برای اجرای این سیاست، وی منصب صدارت را به عنوان منصبی مذهبی- حکو متی ایجاد کرد .این منصب از دوره ی تیموریان ایجاد شده بود ولی در اواخر این دوره اهمیت بیشتری یافت...

B. Ozgen M.E. Cunnane P.A. Caruso H.D. Curtin BACKGROUND AND PURPOSE: Measurement of the vestibular aqueduct on CT scans of the temporal bone is important for the detection of large vestibular aqueduct syndrome; typically this is done in the axial plane. We sought to determine the usefulness of reformats performed in the 45° oblique plane for evaluating the vestibular aqueduct. In addition, we ...
full textThe Human Vestibular Aqueduct: Anatomical Characteristics and Enlargement Criteria.
HYPOTHESIS The human vestibular aqueduct (VA) shows great anatomical variations, and imaging can be difficult, so we need more data on the normal anatomy of the VA for better radiologic evaluation of large vestibular aqueduct syndrome (LVAS). BACKGROUND The normal anatomy of the human VA was analyzed in micro-dissected human temporal bones. METHODS The study is based on two sets of human te...
