1. Cone beam computed tomography with oral contrast for accurate diagnosis and surgical planning of pharyngeal leakage and fistula: a case series
Abstract Objective: Pharyngocutaneous fistula is one of the severe complications related to head and neck surgeries. Detecting the accurate three-dimensional location of both the fistula and leakage is essential for surgical treatment. Videofluoroscopy is usually used for locating these; however, its imaging is two-dimensional. We evaluated pharyngeal leaka

2. Cone beam computed tomographic evaluation of infraorbital canal protrusion into the maxillary sinus and its importance for endoscopic surgery
Abstract Objective: The aim of this retrospective study is to investigate the prevalence of Infraorbital Canal Protrusion (ICP) degree into the maxillary sinus and its relationship with variations in adjacent structures on Cone Beam Computed Tomography (CBCT) images. Methods: 350 CBCT images (700 Infraorbital Canal [IC]) were evaluated retrospectively. ICP

3. 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.

9. Pre-eruptive intracoronal resorption on cone beam computed tomography: two case reports
RESUMO A reabsorção intra-coronária pré-eruptiva (RIP) é uma alteração rara que ocorre na coroa de dentes não erupcionados. O objetivo desse trabalho é documentar dois casos raros de RIP em caninos inclusos nas imagens de tomografia computadorizada de feixe cônico (TCFC). As imagens de TCFC de alta resolução (Prexion 3D) foram solicitadas cuja in

12. Internal configuration of maxillary molars in a subpopulation of Brazil’s Northeast region: A CBCT analysis
Abstract The present study aimed to evaluate the internal configuration of the maxillary molars of a population from the Northeast region of Brazil. Cone-beam computed tomography (CBCT) exams from 512 patients (1501 teeth) were evaluated regarding the anatomical configuration of the root canal system, according to Vertucci’s classification. The images were
