Article Synopsis
  • The study evaluates the AncesTrees software's accuracy using cranial measurements from 114 Brazilian skulls, focusing on European, African, and admixed individuals.
  • The software showed the highest accuracy (73%) for European individuals but struggled with mixed individuals, often classifying them as European.
  • To improve ancestry estimation in Brazil, a more representative database of Brazilian anthropometric data is needed due to the population's high level of admixture.

Article Synopsis
  • The cerebellar interpeduncular region, especially the middle cerebellar peduncle (MCP) and interpeduncular sulcus (IPS), is crucial for surgery due to various vascular and tumor-related issues.
  • A study was conducted using cadaveric heads and human brainstems to analyze the surface and vascular anatomy of these areas to identify safer surgical entry points.
  • Findings suggest that accessing the middle thirds of the IPS and MCP is safer than the upper and lower thirds, as they have fewer blood vessels and important nerve tracts crossing through them.

Article Synopsis
  • This study investigates the "safe entry zones" (EZs) in the brainstem, which are crucial for accessing brainstem pathologies during surgery.
  • The research involved analyzing 26 human brainstems to define safe working areas and distances for various EZs based on key brain structures.
  • Results showed that the transolivary EZ has the largest safe working area, while the supracolicular EZ is identified as the most effective route for accessing specific brain regions like the midbrain tectum and fourth ventricle.

Objective: The cerebellar interpeduncular region (CIPR) is a gate for dorsolateral pontine and cerebellar lesions accessed through the supracerebellar infratentorial approach (SCITa), the occipital transtentorial approach (OTa), or the subtemporal transtentorial approach (STa). The authors sought to compare the exposures of the CIPR region that each of these approaches provided.

Methods: Three approaches were performed bilaterally in eight silicone-injected cadaveric heads.

Background: Patients with Down syndrome (DS) present functional and anatomical alterations that may negatively impact their health and quality of life. Down syndrome patients have been shown to have a high prevalence of temporomandibular disorder (TMD), but little is known about the diagnosis, treatment and prevention in these individuals.

Objective: To evaluate the impact of a home-based multidisciplinary programme on muscular TMD in DS adults.

The cricoid cartilage serves as an anatomical reference for several surgical procedures for access to the airway. Additionally, it serves as an attachment point for muscles that move the vocal folds. We present a case where the cricoid cartilage arch is divided into distinct superior and inferior arches, with a fibrous membrane between them.

Article Synopsis
  • Surviving a gunshot wound to the head is rare, especially in the past when medical treatments were not as advanced, making this specific case from a 1946 skull in a museum collection particularly unusual.
  • This study explores the injury's details through various assessments including trauma classification and CT scan imaging to understand the nature of the wound and the circumstances of the incident.
  • The findings suggest the injury was likely caused by a low-velocity bullet, indicating a high probability of a suicide attempt, but the potential for homicide posing as a suicide also remains a possibility, emphasizing the educational value for forensic anthropology.

Background: Many clinical and experimental studies have been done to analyze the anatomical and functional aspects of the internal auditory canal (IAC) in human beings since there are great inter-individual variability and structural variations that may occur regarding the other adjacent structures.

Objectives: The purpose of this study was to characterize the morphology of the internal auditory canal (IAC) during development using high resolution computed tomography (CT) and to analyze its dimensions, which will be determined by measuring the nearby areas and structures using a system of digital image processing.

Patients And Methods: CT images of the IAC of 110 normal subjects aged 1 to 92 years (mean age, 46.

The objective of this paper was to study the morphology of the articular disc and analyze the immunohistochemical expression of the marker of type IV collagen in the articular disc of the temporomandibular joint (TMJ) of human fetuses of different gestational ages. Twenty TMJ from human fetuses aging from 21 to 24 weeks of intrauterine life were studied. The TMJ were supplied by the Federal University of Uberaba.

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.
