1. The Anatomy and Anatomical Variations of the Round Window Prechamber and Their Implications on Cochlear Implantation: An Anatomical, Imaging, and Surgical Study
Abstract Introduction Over the last decades, there has been a tremendous increase in the number of cochlear implant recipients and, consequently, there is a recent increase of interest in the proper understanding of the anatomy of the round window (RW), which is the most important anatomical land mark during cochlear implant surgery. Objectives The present

2. Imaging Analysis of Onodi Cells on Cone-Beam Computed Tomography
Abstract Introduction Onodi cells are the most posterior ethmoid air cells, and extend superolaterally to the sphenoid sinus. The identification of Onodi cells is essential to because they can have some significant anatomic variations and relationships to vital adjacent structures, like the optic canal, the sphenoid sinus, and the internal carotid artery.

3. Retroperitoneoscopic approach for highly complex posterior renal hilar tumors
ABSTRACT Objectives: To show our single-center experience in retroperitoneoscopic approach for highly complex posterior hilar tumors. Minimally invasive nephron sparing surgery for renal hilar tumors is extremely challenging due to their anatomic location, close to the main renal vessels and the collecting system (1). Transperitoneal approach is feasible, b

4. The anatomic analysis of the vidian canal and the surrounding structures concerning vidian neurectomy using computed tomography scans
Resumo Introdução: O tipo de abordagem endoscópica para a neurectomia do vidiano pode ser definido pela avaliação do canal do vidiano e das estruturas adjacentes aos seios esfenoidais. Objetivo: Investigar as variações e a morfometria do canal vidiano com enfoque nas suas correlações funcionais, pois são parâmetros anatômicos cruciais para o pl

5. Method to Determine the Root Canal Anatomic Dimension by using a New Cone-Beam Computed Tomography Software
Resumo Este estudo discute um método para determinar a dimensão anatômica do canal radicular usando o software e-Vol DX. A metodologia consiste em inicialmente estabelecer as posições corretas que serão medidas, definir o ponto na borda da estrutura anatômica e ajustar a posição intermediária na escala de cinza na imagem em tomografia computadoriza

6. Differentiation between palatal rugae patterns of twins by means of the Briñón method and an improved technique
Abstract Palatal rugae patterns are anatomic structures considered unique to each person. Monozygotic twins present similarities, however, Rugoscopy in particular, may contribute to their individualization for forensic purposes. The aims of this study were: to study the palatal rugae classifications of Briñón; to propose improvements to facilitate use of t

8. Exploratory Analysis of the Distribution of Lignin and Cellulose in Woods by Raman Imaging and Chemometrics
The determinations of cellulose and lignin are important in wood analysis from both perspectives: chemistry composition, commercial and industrial application of woods. In this context, Raman image spectroscopy was applied in the determination of cellulose and lignin distribution in wood surfaces of Swietenia macrophylla King (Mahogany) and Eucalyptus hybrid

9. Influence of radiopacifier additives on calcium aluminate cement properties
The aim of this study was to determine the best radiopaque additive to be incorporated to calcium aluminate cement (CAC) to promote radiopacity. Measurements of optical density were carried out on white MTA and CAC with and without additives such as: polymeric dispersant, plasticizer and various radiopacifiers. The effects of the radiopacifying addition on s

11. Morphological characterization of the nasopalatine region in human fetuses and its association to pathologies
The nasopalatine region is composed of structures such as the vomeronasal organ and nasopalatine duct. The nasopalatine duct may provide the communication of the mouth to the nasal cavity in human fetuses and can be obliterated in an adult human. Knowledge on the development of the nasopalatine region and nasopalatine duct in humans is necessary for understa
