Reliability and accuracy of three imaging software packages used for 3D analysis of the upper airway on cone beam computed tomography images.

Objectives: The aim of this study was to assess the reliability and accuracy of three different imaging software packages for three-dimensional analysis of the upper airway using CBCT images.

Methods: To assess the reliability of the software packages, 15 NewTom 5G (QR Systems, Verona, Italy) CBCT data sets were randomly and retrospectively selected. Two observers measured the volume, minimum cross-sectional area and the length of the upper airway using Amira (Visage Imaging Inc.

Consensus or controversy? The classification and treatment decision-making by 491 maxillofacial surgeons from around the world in three cases of a unilateral mandibular condyle fracture.

Purpose: Many studies are available in the literature on both classification and treatment of unilateral mandibular condyle fractures. To date however, controversy regarding the best treatment for unilateral mandibular condyle fractures remains.

Material And Methods: In this study, an attempt was made to quantify the level of agreement between a sample of maxillofacial surgeons worldwide, on the classification and treatment decisions in three different unilateral mandibular condyle fracture cases.

Positional changes of the masseter and medial pterygoid muscles after surgical mandibular advancement procedures: an MRI study.

This study evaluated whether surgical mandibular advancement procedures induced a change in the direction and the moment arms of the masseter (MAS) and medial pterygoid (MPM) muscles. Sixteen adults participated in this study. The sample was divided in two groups: Group I (n=8) with a mandibular plane angle (mpa) <39° and Group II (n=8) with an mpa >39°.

Aetiology and incidence of maxillofacial trauma in Amsterdam: a retrospective analysis of 579 patients.

Introduction: The incidence of maxillofacial fractures varies widely between different countries. The large variability in reported incidence and aetiology is due to a variety of contributing factors, including environmental, cultural and socioeconomic factors. This retrospective report presents a study investigating the aetiology and incidence of patients with maxillofacial fractures in Amsterdam over a period of 10 years.
