Morphological analysis of the vestibular aqueduct by computerized tomography images.

Objective: In the last two decades, advances in the computerized tomography (CT) field revise the internal and medium ear evaluation. Therefore, the aim of this study is to analyze the morphology and morphometric aspects of the vestibular aqueduct on the basis of computerized tomography images (CTI).

Material And Method: Computerized tomography images of vestibular aqueducts were acquired from patients (n=110) with an age range of 1-92 years.

[Anatomical basis for infraclavicular brachial plexus block].

Background And Objectives: This study shows the constant infraclavicular fossa presence, aiming at using it as a pathway for infraclavicular brachial plexus block. Determining the point where brachial plexus fascicles may be located within the fossa, the authors have proposed measurements from the anterior surface of the clavicle and the angle formed by the deltoid muscle and the clavicle (deltoclavicular angle). The first measurement allows the in-depth location of the site crossed by the brachial plexus.
